conj. 除非,如果不 prep. 除…之外,除非: 例句: Nothing will come of it,unless disaster. 此事除了引起灾祸以外不会有什么结果. 短语: unless and until直到…才 unless的用法例句 Nothing will come of it,unlessdisaster. 此事除了引起灾祸以外不会有什么结果. You never play wellunlessyou practice more. 你若不多加练习永远都弹不好. Nothing could stop me from waiting for you to come backunlessdeath. 除了死亡再没有别的事物能够阻止我等待你回来. 我们很多时会在特定条件下,才决定做或不做一件事.中文用的连接词一般是「除非」和「否则」.例如: 除非挂起八号或以上风球,否则演唱会将如期举行. 「除非」带有反义 上句实际要说的是,如果出现某个条件,某件事不会进行.挂八号或以上风球,演唱会「不会」如期举行.然而,采用「除非」和「否则」的结构,却是反过来说,某个条件「不」出现的话,某件事继续进行.「不」挂八号以上风球,演唱会如期举行.可以说,「除非」是带有反义的. 英文的unless也有这个作用,以文首的中文句子为例: The concert will be held as scheduled unless typhoon signal no.8 or higher is hoisted. 试比较: The concert will be held as scheduled if typhoon signal no.8 or higher is not hoisted. 这就说明了「只要」后面的条件不出现,前面的事可以进行.试举另一个例句更清楚说明: She will keep on singing unless she is told to stop. 她会一直唱下去,除非有人叫她停止. 试比较: She will keep on singing if she is not told to stop. 想表达肯定语气 就不用unless 另一个用法是,我们表明不会做一件事,除非某个条件出现.那么主句应该用否定语.即是说,我们并未或不打算进行这件事.例如: I will not go to Beijing unless the company pays for the trip. 我不会去北京,除非公司支付旅费. 以上句为例,如果想在主句表达肯定的语气,就不能用unless,可以写成: I will go to Beijing only if the company pays for the trip. 我会去北京,假如公司支付旅费. 然而,应用时必须留意句子动词的时态.虽然以unless所说的条件,都是未出现或未发生的,但必须用简单现在式(simple present),不能用将来式或其他时态. I will not go to Beijing unless the company pays for the trip.(不能用will pay) 其实unless 和if 都是连接词,意思不同,但同样说出一些条件(condition),用法相似. 以上是应用unless时一些必须注意的情况,宜紧记,以免出错.

unless引导什么从句是什么意思

unless的定义:unless意为“除非;如果不”; unless引导的条件状语从句规则:若主句为一般将来时,那么从句常用一般现在时表将来——主将从现; unless引导的条件状语从句可与if……not引导的条件状语从句进行互换。 扩展资料   Unless I"m mistaken, she was back at work yesterday.   除非是我记错了,她是昨天回来上班的。   Unless we start making some sales, we"re done for.   如果我们还卖不出去,那我们就完了。   I sleep with the window open unless it"s really cold.   天气若不很冷,我总开着窗户睡觉。   Unless something unexpected happens, I"ll see you tomorrow.   如果不出意外,我明天去看你。   They refused to release their hostages unless certain conditions were met.   除非某些条件得到满足,否则他们不会释放人质。

unless的用法和例句

一、unless的基本用法连词unless:意为“除非……如果不……”,“除了……”,多引导一个否定意义的真实条件句,有时也可引导非真实条件旬。unless引导条件句时(1) 主句为肯定句。如:Unless I visit every bookstore in town.I shall not know whether I can get what l want.如果我不到城里每一家书店去看看,我就不知道是否能买到我想要的书。You will miss the bus unless you hurry up.你要不快点就会错过班车。You"ll fail in chemistry again unless you work harder.如果你不再加把劲,你化学考试还会不及格。(2) 主句为否定句。如:Unless you oil the motor regularly.it won"t run smoothly.要不是你经常给发动机上油。它就不会转得那么顺畅。I wouldn"t be saying this unless I were sure of the facts.要是我对这些事情没有把握,我就不说这话了。You will never get anywhere unless you have set your goal.如果你不设定目标,你哪儿也去不了。二、应注意的一些问题1.unless不能与if....not换用的情况unless在意义上相当于if...not,因此在有些场合中unless与if...not可互换使用。如:Unless I am mistaken.I"ve seen that man before.=If I am not mistaken。I"ve seen that man before.如果我没搞错,我以前见过那个人。Unless the strike has been called off,there will be no trains tomorrow.=If the strike has not been called off。there will be no trains tomorrow.除非罢工结束了,明天才会有火车。

unless什么意思

unless的意思有:除非;除非在…情况下;若非;如果不。一、词语读音。英 [u0259nu02c8les] ,美 [u0259nu02c8les] 。二、词语词性。连接词(conj)。三、词语用法。连词unless意为“除非……如果不……”,“除了……”,多引导一个否定意义的真实条件句,有时也可引导非真实条件旬。unless引导条件句时,主要用于下列情况。1、主句为肯定句。如:u2002Unlessu2002Iu2002visitu2002everyu2002bookstoreu2002inu2002town.Iu2002shallu2002notu2002knowu2002whetheru2002Iu2002canu2002getu2002whatu2002l want.如果我不到城里每一家书店去看看,我就不知道是否能买到我想要的书。2、主句为否定句。如:u2002Unlessu2002youu2002oilu2002theu2002motoru2002regularly.itu2002won"tu2002runu2002smoothly.要不是你经常给发动机上油。它就不会转得那么顺畅。扩展资料:unless是从属连词,引导条件状语从句,含有否定意义,相当于if条件状语从句的否定形式。所以unless在意义上相当于if...not,因此在有些场合中unless与if...not可互换使用。如:Unlessu2002Iu2002amu2002mistaken.I"veu2002seenu2002thatu2002manu2002before.也可写为:lfu2002Iu2002amu2002notu2002mistaken. I"veu2002seenu2002thatu2002manu2002before。意思是:如果我没搞错。我以前见过那个人。但在有些情况下,二者不可互换使用。u20021、当unless引导非真实条件句时,一般不可改用if...not。如:Theyu2002couldn"tu2002affordu2002tou2002liveu2002inu2002suchu2002anu2002expensiveu2002apartmentu2002unlessu2002theyu2002wereu2002rich。除非他们很富有,否则就住不起这么昂贵的公寓。以上例中,unless从句均表示与事实相反的情况。如果把unless换成if...not(…ifu2002they wereu2002notu2002rick,…ifu2002theu2002policeu2002hadu2002notu2002hadu2002au2002helicopter)就与原句意义完全相反了。2、if...not引导的条件分句可以重叠使用,unless则不可,因为unless表示唯一条件,不能用and连接两个unless引导的从句。如:Sheu2002won"tu2002loseu2002weightu2002ifu2002sheu2002doesu2002notu2002keepu2002au2002dietu2002andu2002ifu2002sheu2002doesu2002notu2002takeu2002exerciseu2002everyu2002day。意思为:除非她坚持节食、每天锻炼,否则是不能减肥的。3、当if引导名词性从句时,unless不可以代替if...not,因为if=whether(“是否”)。如:Itu2002isu2002unimportantu2002ifu2002heu2002willu2002notu2002attendu2002theu2002graduationu2002ceremony。意思为:他是否参加毕业典礼无关紧要。4、当unless作介词(“除……以外”,“除非”)时,if...not不能与其互换使用。如:Nothingu2002willu2002comeu2002outu2002ofu2002it.unless disaster。意思是:这件事除了引起灾祸之外,不会有什么结果。

unless是什么意思

高考英语词汇:unless与if...not的用法

两者都可表示否定的条件,有时可换用。如:   Come tomorrow unless I phone [if I don"t phone]. 要是我没有打电话,明天就来。   You won"t catch the train unless you hurry [if you don"t hurry]. 你要是不赶快,你就赶不上火车了。   但是在下列情况下,通常要用 if ... not 而不用 unless:   1. 当所述条件要引出一种新的想法或情况(而不是结束已存在的想法或状态)时。如:   I"ll be angry if I"m not invited to the party. 如果不邀请我参加晚会,我会生气的。(即“不邀请我去参加晚会”会导致一种新情况——“我会生气”)   I will be surprised if he doesn"t have an accident. 他要是不出事,我倒感到奇怪了。(即“他不出事”会导致一种新情况——“我感到奇怪”)   2. 当要引出一个表示假想的(imaginary)条件句时。如:   If he weren"t so silly, he would understand. 他要不是那样傻的话,他就会明白了。(实际上他很傻)   If I hadn"t stopped her, she would have jumped down. 要不是我阻止了她,她就跳下去了。(实际上我阻止了她)   注:偶尔可见到 unless 用于假想条件句,但有不少语法家反对这一用法,建议学生不要模仿。顺便说一句,unless 有时用于引出一个补充前言的话(此时通常用破折号而不用逗号且不能用 if ... not 替换),此时若谈论的是过去的情况,注意不要与表示想象的条件句相混淆。如:   I couldn"t have got to the meeting on time — unless I had caught an earlier train. 我不可能及时赶到会场,除非我赶上了较早的一班火车。(事实是“我”没有及时到会)   若将上句中的 unless 换为 if ... not,则意思有很大差别:   I couldn"t have got to the meeting on time if I had not caught an earlier train. 要是我没有赶上早一班火车,我就不可能及时到会了。(事实是“我”及时到会了)

unless意思?

unless中文翻译的意思是:除非。

until unless 区别

until 是直到 unless 是除非

unless可以用于虚拟语气(条件状语从句中的虚拟条件句)吗?

unless是从属连词,引导条件状语从句,含有否定意义,相当于if条件状语从句的否定形式。If引导的条件状语从句有两种,真实和非真实,当unless=ifnot时可以引导虚拟条件句,当从句所表达的条件是有可能实现的、有可能是真实的条件时,用真实条件句,如果从句所表达的条件是不可能实现的、与客观事实完全相反的条件或假设时,用虚拟条件句。这句话中是有可能实现的:除非朱丽叶一起做,否则我们就决定不做了。主句中用了过去完成时,从句根据说话的语义,用过去式所以选Ddid希望对你有帮助哦~

unless后动词用什么形式

unless引导条件状语从句,主将从现,主句用将来时,从句用一般现在时theconcertwillbeheldasscheduleunlessthereisatyphoon.=theconcertwillbeheldasscheduleifthereisnotatyphoonshewillkeeponsingingunlesssheistoldtostop.otherwise作连词,意为“否则;不然”,相当于or或ifnot。otherwise是虚拟语气的用法,其后用情态动词+do/havedone如:we"llgoearly,otherwisewemaynotgetaseat.我们得早点去,要不然就没有座位了。iwasillthatday,otherwiseiwouldhavetakenpartinthesportsmeet.那天我病了,否则我会去参加运动会的。

用unless怎么造句?

unless是连词,引导条件状语从句,意为“除非。。。;如果不。。。”,相当于“if...not...”。 学生们用它造句的难点在于,常常不知主句部分用肯定还是否定,此时,只要把unless从句变为“if...not...”的形式,意思就清楚了。例如: I won`t go to her party unless I am invited. = I won`t go to her party if I am not invited. “除非被邀请,否则我不会去她的聚会”= “如果没有被邀请,我就不会去她的聚会”再比如: You will miss the train unless you harry up. = You will miss the train if you don`t hurry up. "如果不快点的话,你会赶不上火车。"PS:unless引导的条件状语中,可用一般现在时表将来,即我们常说的“主将从现”。 希望可以帮到楼主,学习加油哟~

unless引导的条件状语从句,时态是主将从现还是时态一致?

差不多的,主将从现是用在条件状语和时间状语中的,if和unless引导的条件状语从句而已算是其中一种;主将从现常见的有以下四种情况:一、条件状语从句的主句是一般将来时,那么从句常常用一般现在时如:WhenIgrowup,I"llbeanurseandlookafterpatients我长大后要当一名护士,照顾病人二、如果主句是祈使句,那么从句通常要用一般现在时如:Don"tlaughatmewhenImakeamistake.我犯错误的时候不要笑话我。三、如果主句是含有情态动词的一般现在时,根据需要从句多用现在进行时如:Youshouldbequietwhenyouareinthereadingroom在阅览室时应保持安静四.如果if的条件状语从句遇到变换间接和直接时,祈使句应用notto....如;Shesaidnottoclosethewindow常见的时间状语从句的连词有:assoonas,when,while,as,until等用在unless或if中可以是下面的用法:Iwillnotgoboatingifitrainstomorrow.Unlessyouhavefinishyourhomework,Iwon"tallowyoutowatchTV.

英语用unless造句

you will not succeed,unless you work hard.

unless和until的用法?

unless和until的用法区别.一、作为从属连词含义不同,引导从句性质不同unless与until均为从属连词,unless表“除非”,强调条件,引导条件状语从句;until表“直到”,强调时间的延续,引导时间状语从句.1.I didn"t know the news until my teacher told it to me.2.I couldn"t know the news unless my teacher told it to me.3.—Was his father very strict with him when he was at school?—Yes.He had never praised him until he became one of the top students in his grade.析:句1动词didn"t know表明该句强调时间的延续,表“我不知道这消息”的状态一直延续到“老师告诉我”,因此应用until引导时间状语从句.句2动词couldn"t know表明该句强调条件,表“我不可能知道这消息,除非老师告诉我”,因此应用unless引导条件状语从句.句3表明“他爸爸从来没有表扬他”的状态一直延续到“他变成年级最好的学生之一”,因此也应用until引导时间状语从句.二、作为从属连词引导的从句常用一般现在时表示将来unless引导的条件状语从句和until引导的时间状语从句常用一般现在时表示将来.例1:除非邀请你否则别进来.误:Don"t come in unless you will be invited to.正:Don"t come in unless you"re invited to.例2:除非他来,我们不可能去.误:Unless he will come,we won"t be able to go.正:Unless he comes,we won"t be able to go.三、作为从属连词引导的状语从句可转换为省略式创新句型unless引导条件状语从句和until引导时间状语从句时,如果主从句主语一致(或主从句主语不一致,但从句主语为it),从句谓语部分含有be,可将从句主语和动词be省略,构成省略式创新句型.例1:I won"t come to see you unless I am asked to.除非你邀请我,我才会来看你.析:因为主从句主语一致,从句谓语又含有am,所以可将从句主语I和动词am 省略,构成省略式创新句型:I won"t come to see you unless asked to.例2:The soldiers will not cross the river unless they are ordered to.除非接到命令,战士们不会过河.析:因为主从句主语一致,从句谓语又含有are,所以可将从句主语they和动词are省略,构成省略式创新句型:The soldiers will not cross the river unless ordered to.注意:until也可作为介词.例如:I have remembered her until now.直到现在我还记得她.来自北京四中网校

unless的反义词?

unless 由un和less组成。un是否定前缀,若将un去掉,则为less。按理说unless和less为相反的。这是一种反义词的对立感以及矛盾感。故反义词是less

unless和until区别在哪里?

1、意思不同unless=if not....除非,如果...不。until=before.....在...之前。2、侧重不同unless,表示一种条件关系,即从句表示为主句动作所发生的条件,具备从句的提供的条件就会出现主句所表现的结果。until,表示一种时间关系,主句动作在从句所表示时间之前不发生。3、用法不同unless,强调条件,引导条件状语从句。until,强调时间的延续,引导时间状语从句。

求unless 用法。

unless 是“除非”的意思,通常放在句首或句末。句式: 主句+unless+从句 ,主句从句都可以是完整的句子。 但在下列情况下二者不能换用: 1)表示“由于未发生B而发生A”的句子只能用if…not, 而不用unless。例如: I"d be glad if she doesn"t come this evening. 如果今天晚上她不来我将很高兴。 2)if…not可以引导一个虚拟条件句,unless一般不引导虚拟条件句。例如: If she weren"t so silly, she would understand. 例句: Nothing will come of it, unless disaster. 《21世纪大英汉词典》 You will not make a good teacher, unless you feel teaching is your vocation . 除非你觉得教书是你的天职,否则你不会成为一位好老师。 dict.veduchina.com Sufferers have trouble concentrating on any task unless they receive constant feedback, stimulation and reward. 除非得到经常反馈、刺激、奖励,童患者很难专心致志于任何任务。

unless和until的区别

unless 是除非...否则..的意思 until 是直到...才.. 的意思它们是两个不同的意思. until 表示:prep.在…以前;到…为止 unless 表示:conj.除非,如果不 扩展资料   一、作为从属连词含义不同,引导从句性质不同   unless与until均为从属连词,unless表“除非”,强调条件,引导条件状语从句;until表“直到”,强调时间的延续,引导时间状语从句。   1. I didn"t know the news until my teacher told it to me.   2. I couldn"t know the news unless my teacher told it to me.   二、作为从属连词引导的从句常用一般现在时表示将来   unless引导的条件状语从句和until引导的"时间状语从句常用一般现在时表示将来。   三、作为从属连词引导的状语从句可转换为省略式创新句型   unless引导条件状语从句和until引导时间状语从句时,如果主从句主语一致(或主从句主语不一致,但从句主语为it),从句谓语部分含有be,可将从句主语和动词be省略,构成省略式创新句型。   例1:I won"t come to see you unless I am asked to. 除非你邀请我,我才会来看你。   析:因为主从句主语一致,从句谓语又含有am,所以可将从句主语I和动词am 省略,构成省略式创新句型:I won"t come to see you unless asked to.

unless的用法,怎么用

unless除非=if not

unless什么意思?

除非

unless后面可以直接doing吗

unless后面可以直接doing。解析:unless作介词,意思除...外,在一般情况下,动词+ing可以。unless一、含义:conj. 除非;如果不。prep. 除 ... 外。二、用法:unless所引导的条件状语从句常用一般现在时表示将来意义,主句多用一般将来时。unless在表示“除非”时,如其引导的从句谓语是be,而从句的主语跟主句的主语相同时,从句的主语和be就可省略。有时从句中主语为it时,也可省略it或从句中的有关成分。Let"s have dinner out—unless you are too tired.咱们出去吃饭吧——除非你太累了。近义词:but一、含义:conj. 但是。prep. 除 ... 以外。adv. 仅仅;只。pron. 无不。二、用法:but的基本意思相当于in spite of this或表示与所预料的不一样,意为“但是,然而,尽管如此”,不与though,although连用。but可用来表达诸如愤怒、吃惊等强烈的感情,用来加强语气,也可用在表示歉意的句子里,常不译出,还可用于改变话题,意为“无论如何”“反正”“好”。He"s still but a child.他仅仅是个小孩子。

unless怎么读

unless的发音为英语单词中的/ʌnˈlɛs/,读作"un-less"。下面将以不同角度进行详细解释。1.音标和发音unless是个连词,表示"除非"或"如果不"的意思,其中的音标为/ʌnˈlɛs/,其中"/ʌ/"为央元音,"/n/"为鼻音,"/ˈlɛs/"为重音+清辅音+前元音。要注意把"un"和"less"这两个单词连接在一起形成一个词,发音时不要断开。2.用法和示例unless通常连接两个句子,表示在某种条件下才能实现后面的动作。例如:"I won"t leave unless you come with me."(除非你跟我一起走,否则我不会离开)"Unless it rains tomorrow, we"ll go hiking."(如果明天不下雨的话,我们会去徒步旅行)3.替代词汇如果想使用其他单词代替"unless",可以考虑使用"if not"、"except"或者"but"等词。例如:"If not for your help, I wouldn"t have succeeded."等价于"I wouldn"t have succeeded unless you helped me."4.特殊情况的用法在某些情况下,"unless"也可以被用作副词或名词。作为副词时,可以表示否定的概念,类似于"except",例如:"I failed in everything unless in geometry."(除了几何学以外,我什么都没通过)作为名词时,可以指代某个条件未满足的情况。例如:"We"ll go ahead with the plan, unless there are any objections."(如果没有反对的意见,我们就会继续执行计划)5.与其他连词的区别"unless"和其他连词,如"if"、"when"和"although"等,结构上有很大的差异。"if"表示假设,通常表示对一件事情进行条件的限制;"when"表示时间点,表示在某个时刻才能完成后面的动作;"although"表示转折关系,表示前面的描述和后面的描述不一致。而"unless"则是一种特殊的条件连词,表示在某种条件下才能实现后面的动作。总之,"unless"是一个常用的英语单词,表示"除非"或"如果不"的意思。在掌握了正确的发音和基本用法后,可以通过理解替代词汇、特殊用法等更深层次的知识来更好地应用于实际场景中。

Unless 的用法

一、unless的基本用法连词unless意为“除非……如果不……”,“除了……”,多引导一个否定意义的真实条件句,有时也可引导非真实条件旬。unless引导条件句时,主要用于下列情况。(1)主句为肯定句。如:Unless I visit every bookstore in town.I shall not know whether I can get what l want.如果我不到城里每一家书店去看看,我就不知道是否能买到我想要的书。You will miss the bus unless you hurry up.你要不快点就会错过班车。You"ll fail in chemistry again unless you work harder.如果你不再加把劲,你化学考试还会不及格。(2)主句为否定句。如:Unless you oil the motor regularly.it won"t run smoothly.要不是你经常给发动机上油。它就不会转得那么顺畅。I wouldn"t be saying this unless I were sure of the facts.要是我对这些事情没有把握,我就不说这话了。You will never get anywhere unless you have set your goal.如果你不设定目标,你哪儿也去不了。二、应注意的一些问题1.unless不能与if""not换用的情况unless在意义上相当于if...not,因此在有些场合中unless与if...not可互换使用。如:Unless I am mistaken.I"ve seen that man before.=lf I am not mistaken。I"ve seen that man before.如果我没搞错,我以前见过那个人。Unless the strike has been called off,there will be no trains tomorrow.=lf the strike has not been called off。there will be no trains tomorrow.除非罢工结束了,明天才会有火车。但在有些情况下,二者不可互换使用。如:(1)当unless引导非真实条件句时,一般不可改用if...not。如:They couldn"t afford to live in such an expensive apartment unless they were rich.除非他们很富有,否则就住不起这么昂贵的公寓。They couldn"t have arrived at the site instantly unless the police had had a helicopter.除非警方有直升机,不然他们就不会即刻赶到事发地点。以上两例中,unless从句均表示与事实相反的情况。如果把unless换成if...not(…if they were not rick,…if the police had not had a helicopter)就与原句意义完全相反了。(2)if...not引导的条件分句可以重叠使用,unless则不可,因为unless表示唯一条件,不能用and连接两个unless引导的从句。如:She won"t lose weight if she does not keep a diet and if she does not take exercise every day.=She won"t lose weight unless she keeps a diet and takes exercise every day.除非她坚持节食、每天锻炼,否则是不能减肥的。(3)unless引导的条件句可用否定结构,而if...not引导的条件句不可再加以否定,因为两个not不能重叠使用,因此在unless引导的否定条件旬中,不能用if...not替代unless。如: Don"t ask me to explain unless you really don"t understand.除非你真不懂,不然别让我解释。The directors have a meeting every Friday.unless there is nothing to discuss.董事会每周五开会,无事讨论除外。You will get a good grade in the course unless you don"t do your homework.如果你(不是不)做作业的话,你就会有好的学业成绩。(4)当if引导名词性从句时,unless不可以代替if...not,因为if=whether(“是否”)。如:It is unimportant if he will not attend the graduation ceremony.他是否参加毕业典礼无关紧要。I doubts if he has not made a contribution to the environment.我怀疑他是不是没有为环保做过贡献。(5)当unless作介词(“除……以外”,“除非”)时,if...not不能与其互换使用。如:Nothing will come out of it.unless(=except)disaster.这件事除了引起灾祸之外,不会有什么结果。Nothing.unless a miracle,can save him.除非出现奇迹,否则他无法得救。2.unless从句中成分的省略unless从句的主语与主句的主语相同时,unless从句中的主语和谓语(或一部分)有时可省略。如:Unless(he is)in uniform。he doesn"t look like a policeman.如果不穿上制服,他看起来就不像警察。Unless(I am)compelled t0 stay in by bad weather,I go for a walk every day.若非天气不好被迫呆在家里,我每天都出去散步。Don"t leave the building unless(you are)instructed to do so.没有得到通知,不要离开大楼。The virus is capable of destroying an information stored in a computer unless(it is)detected and eradicated.病毒如不查出并清楚掉,会把存储在计算机里的资料全部毁掉。3.unless从句的时态主句是一般将来时态、祈使句或谓语中含有情态动词或主句是一般现在时,unless引导的真实条件句用一般现在时;如果强调从句动作发生在主句动作之前,从旬可用现在完成时。Don"t touch the instruments unless the teacher allows you.没有老师的允许,不要乱动仪器。Unless you know a word,you may consult a dictionary.如果你不认识哪个词,你可以查词典。但主句是过去将来时或过去时,unless引导的真实条件句常用一般过去时。如:The disease prevented him from remembering things unless he was reminded by another.这种病使他记不住事,只能靠别人提醒。4.“祈使句(肯定式)+or/otherwise+陈述句”与“unless条件句+主句”间的转换“祈使旬(肯定式)+or(else)/otherwise+陈述句”与“unless条件句+主句”间有时可以相互转换。如:Put on your raincoat or you"ll get soaked.=Unless you put On your raincoat,you"ll get soaked.If you don"t put on your raincoat,you"ll get soaked.把雨衣穿上,否则你就会全身湿透的。Store the meat in the fridge,otherwise it will go the fridge,otherwise it will go off.If you don"t store the meat in the fridge,it will go off.把肉放在冰箱里,不然就会坏掉。5.在unles引导的肯定形式的条件句中。通常用肯定词(some,already, still,too,as well等);在if...not引导的条件句中.通常用非肯定词(any.yet.ever.either.at all等)You ll never really know what happiness is unless you have something to compare it to.只有通过对比,才能了解幸福的含义。1 will inform her if you haven"t spoken to her yet.如果你还没跟她说,我通知她。不过在if…not引导的非真实条件句中,仍能用肯定词,因为这种条件句形式上是否定,意义上却是肯定。如:If he hadn"t already prepared his lesson,he wouldn"t be allowed to go.要是他没有做完功课,是不会允许出去的。(实际已做完功课)6.unless可用来引导出补充前言的句子unless引导出补充前言的句子,即对刚说过的话又突然想到要补充的内容。如:He hasn"t got any hobbies unless you call writing a hobby.他没有任何嗜好——除非把写作也算作嗜好。Let"s play chess unless you really have something urgent to do.下盘棋吧——除非你真有急事要办。

handy seamless transitions 怎么安装

有时候WEB开发人员认为CSS的动画比JavaScript的动画更难理解。虽然CSS动画有其局限性,但它的性能比大多数JavaScript库更加高效,因为它可以借助硬件加速啊!其效果绝对可以超出我们的预期。CSS animations和transitions再加上点JavaScript就可以实现硬件加速动画,而且其交互效果比大多数JavaScript库更高效。So,让我们快点开始吧!小伙伴们都等不及了!注意:Animations(动画)和Transitions(过渡)是不同的CSS Transitions(过渡)被应用于元素指定的属性变化时,该属性经过一段时间逐渐的过渡到最终需要的值;而CSS Animations(动画)只是在应用时执行之前定义好的操作,它提供更细粒度的控制。在这篇文章中,我们将分别针对上述内容进行讲解。控制CSS Transition(过渡)在编程论坛中,关于transition(过渡)的触发和暂停有无数的疑问。使用JavaScript可以很容易的解决这些疑问。如何触发元素的transiton(过渡)?切换元素的类名可以触发该元素的transition(过渡)如何暂停元素的transition(过渡)? 在你想要暂停过渡点,用getComputedStyle和getPropertyValue获取该元素相应的CSS属性值,然后设置该元素的对应的CSS属性等于你刚才获取到的CSS属性值。以下是该方法的一个例子。<!DOCTYPE html><html><head><title>操作transtition</title><style type="text/css">.box {margin: 30px;height: 50px;width: 50px;background-color: blue;}.box.horizTranslate {-webkit-transition: 3s;-moz-transition: 3s;-ms-transition: 3s;-o-transition: 3s;transition: 3s;margin-left: 50% !important;}</style><script type="text/javascript" src="js/jquery.js"></script></head><body><h3>Pure Javascript</h3><div class="box"></div><button class="toggleButton" value="play">Play</button><h3>jQuery</h3><div class="box"></div><button class="toggleButton" value="play">Play</button><script type="text/javascript">var boxOne = document.getElementsByClassName("box")[0],boxTwo = $(".box:eq(1)");document.getElementsByClassName("toggleButton")[0].onclick = function(){if(this.innerHTML === "Play"){this.innerHTML = "Pause";boxOne.classList.add("horizTranslate");}else{this.innerHTML = "Play";var computedStyle = window.getComputedStyle(boxOne),marginLeft = computedStyle.getPropertyValue("margin-left");boxOne.style.marginLeft = marginLeft;boxOne.classList.remove("horizTranslate");}}$(".toggleButton:eq(1)").on("click",function(){if($(this).html() === "Play"){$(this).html("Pause");boxTwo.addClass("horizTranslate");}else{$(this).html("Play");var computedStyle = boxTwo.css("margin-left");boxTwo.css("margin-left",computedStyle);boxTwo.removeClass("horizTranslate");}});</script></body></html>执行效果:http://cdpn.io/GokAm同样的技术可以用在更高级的方法上。下面的例子也是通过改变类名来触发元素的transition(过渡),但这次可以跟踪当前的缩放率。<!DOCTYPE html><html><head><title>操作transtition</title><style type="text/css">.zoomPic {margin: 30px;width: 300px;height: 180px;background-color: blue;background-image: url(http://placehold.it/1200x720);background-repeat:no-repeat;background-position:50% 50%;background-size: 300px 180px;-webkit-transition: all 2.5s ease-in-out;-moz-transition: all 2.5s ease-in-out;-ms-transition: all 2.5s ease-in-out;-o-transition: all 2.5s ease-in-out;transition: all 2.5s ease-in-out;}.zoomPic.zoom {background-size: 1200px 720px !important;}</style><script type="text/javascript" src="js/jquery.js"></script></head><body><h3>Pure Javascript</h3><div class="zoomPic"></div><button class="zoom">Zoom</button><button class="pause">Pause</button><button class="zoomout">Zoom Out</button><h3>jQuery</h3><div class="zoomPic"></div><button class="zoom">Zoom</button><button class="pause">Pause</button><button class="zoomout">Zoom Out</button><script type="text/javascript">var zoomOne = document.getElementsByClassName("zoomPic")[0],zoomOneBgSize = window.getComputedStyle(zoomOne).getPropertyValue("background-size"),zoomTwo = $(".zoomPic:eq(1)"),zoomTwoBgSize = zoomTwo.css("background-size");// zoomOne:zoomdocument.getElementsByClassName("zoom")[0].onclick = function(){if(!zoomOne.classList.contains("zoom")){zoomOne.classList.add("zoom");}}// zoomOne:pausedocument.getElementsByClassName("pause")[0].onclick = function(){var computedStyle = window.getComputedStyle(zoomOne),backgroundSize = computedStyle.getPropertyValue("background-size");zoomOne.style.backgroundSize = backgroundSize;zoomOne.classList.remove("zoom");}// zoomOne:zoomoutdocument.getElementsByClassName("zoomout")[0].onclick = function(){zoomOne.classList.remove("zoom");zoomOne.style.backgroundSize = zoomOneBgSize;}// zoomTwo:zoom$(".zoom:eq(1)").on("click",function(){if(!zoomTwo.hasClass("zoom")){zoomTwo.addClass("zoom");}});// zoomTwo:pause$(".pause:eq(1)").on("click",function(){var computedStyle = zoomTwo.css("background-size");zoomTwo.css("background-size",computedStyle);zoomTwo.removeClass("zoom");});// zoomTwo:zoomout$(".zoomout:eq(1)").on("click",function(){zoomTwo.removeClass("zoom");zoomTwo.css("background-size",zoomTwoBgSize);});</script></body></html>

新概念英语第2册Lesson16~18重要语法

新概念英语第2册Lesson16重要语法   一、重要句型或语法   if条件句   在第一册第137-138课里已经学过了if引导的条件状语从句,当时侧重的是“主将从现”的原则的运用。本课的if条件句在“从现”的基础上,又增加了从句使用其他时态的情况,如:现在进行时(If he is working, I won"t disturb him.)。此外,还出现了与情态动词连用的情况,如:He will come tomorrow if he can.   二、课文主要语言点   If you park your car in the wrong place, a traffic policeman will soon find it. 1)注意park(熄火停车)和stop(临时停车)的区别。 2)wrong,错误的。与right相反。 3)注意交警的表达:traffic policeman。 4)句中的it指的是前半句中所说的“车子停错位置”。   You will be very lucky if he lets you go without a ticket. 1)let sb. go,放过某人。 2)ticket,罚款单。   However, this does not always happen. 这句话要注意联系前后文来理解,本句所说的这种情况(this)不常发生,指的是交警不总是很严厉。本句话可以作为套话来用,表达某种情况不常发生时用。   Traffic police are sometimes very polite. 1)police是警察的总称,用作复数。 2)本句话就验证了前一句话暗含的意思,即交警有时也很客气。   During a holiday in Sweden, I found this note on my car: "Sir, we welcome you to our city. This is a "No Parking" area. You will enjoy your stay here if you pay attention to our street signs. This note is only a reminder." 1)note,便条。 2)welcome sb. to somewhere,欢迎某人到某地。 3)This is a "No Doing" area,可以作为固定句型来用,表示某地禁止干嘛,如:This is a "No Smoking" area. 4)enjoy one"s stayy,相当于enjoy oneself。 5)pay attention to,注意到。 6)street sign,街道路牌。 7)reminder,提示。源自动词remind(提醒)。   If you receive a request like this, you cannot fail to obey it. 1)注意receive的拼写。不要把ei拼写成ie。 2)request,礼貌的请求。 3)cannot fail to do,不会不、肯定会做某事。这是双重否定的结构,更具强调效果。 4)obe,服从、遵守。   三、读写重点   注意尾重原理在if条件句中的运用,即:if条件句从语法角度来看,可前置也可后置,只是前置时,要注意一般句末要用逗号与主句隔开;但从读写角度来看,不能随意摆放if条件句,如果要强调条件句本身,就后置到主句后。 新概念英语第2册Lesson17重要语法   一、重要句型或语法   情态动词must   must主要的用法有:   1)表必须,如:   肯定句:He must finish the job now.   否定句:He needn"t finish the job now.   一般疑问句及其回答:Must he finish the job now? Yes, he must. / No, he needn"t.   2)表猜测,如:He must be over forty.   二、课文主要语言点   My aunt Jennifer is an actress. 1)Jennifer是my aunt的同位语,其补充说明作用。注意aunt存在英美语发音上的差异。 2)actress,女演员。原形为act,表示表演。actor,男演员。   She must be at least thirty-five years old. 1)句中的must表猜测,是对she当前的年龄的猜测,所以直接使用了must be的形式。 2)at least,至少。相反的表达为:at most。   In spite of this, she often appears on the stage as a young girl. 1)in spite of,尽管,是个介词短语,后面不能接句子。 2)appear on the stage,在舞台上表演。 3)as,表示作为、担任。   Jennifer will have to take part in a new play soon. 1)will have to,表示她将不得不。 2)take part in,参加。   This time, she will be a girl of seventeen. 1)this time后面用逗号隔开,起到强调作用,凸显这次她要扮演的角色。 2)a girl of seventeen,十七岁的女孩。类似的表达有:a boy of seven。   In the play, she must appear in a bright red dress and long black stockings. 1)in+衣服,表示穿着...衣服。 2)bright red,鲜红色。   Last year in another play, she had to wear short socks and a bright, orange-coloured dress. 1)注意wear(穿着,强调状态)与put on(穿上,强调动作)的区别。 2)orange-coloured,橙色的。也可以直接用orange来表示。   If anyone ever asks her how old she is, she always answers, "Darling, it must be terrible to be grown up!" 1)if anyone ever asks her how old she is,注意句中的how old she is的语序,虽然是问句,但因为用在宾语从句中,所以要用陈述句语序。 2)it must be terrible to be grown up,must表猜测。grown up,成熟的、成人的。   三、读写重点   注意解读Jennifer最后的一句话“Darling, it must be terrible to be grown up!”,表达出了Jennifer害怕青春逝去的担心。 新概念英语第2册Lesson18重要语法   一、重要句型或语法   have的用法   have作为实义动词的主要用法有:   1)表“有”,如:He has some magazines.   2)表“吃喝‘,如:He has a cup of tea every day.   3)表“患病”,如:He has a bad cold.   4)表“万能do”,其结构一般为:have a+含动作含义的名词,如:have a swim/talk/walk/rest等。   二、课文主要语言点   After I had had lunch at a village pub,   I looked for my bag.   1)have表“吃喝”时,一般后面会跟上吃喝的东西,但是如果是笼统说吃喝,则一般用eat或drink,如:have something to drink/eat。 2)可提问学生为什么句中的have lunch的have要用过去完成时had had lunch。 3)注意表地点的介词at的用法,因为a village pub是小地方,是某个点。 4)look for,寻找。可以在此汇总look的相关短语,如:look after/look up/look up to/look down on。   I had left it on a chair beside the door and   now it wasn"t there!   1)句中的leave表示“落下,忘了”。 2)注意区分beside(在旁边)和besides(除了...之外,还有)。 3)注意跟学生解释后半句虽然用的是now,但因为说的是钱包当时放在门边,之后就不见了,所以是过去的事情,要用一般过去时。   As I was looking for it, the landlord came in. 1)as相当于while,其引导的从句谓语动词一般都要用进行时。 2)注意landlord的构词方式属于合成法,即是由land(土地)和lord(主人)构成的。   Did you have a good meal?" he asked. 1)可提问学生为什么店主询问时要用一般过去时(因为店主问的是过去发生的事情,即刚才作者吃的饭如何)。 2)have a good meal,吃得好。   Yes, thank you," I answered, "but I can"t pay the bill.   I haven"t got my bag."   1)pay the bill,买单、付账。 2)have got,对比have的用法,have got更加口语化,且have got中的have是助动词。   The landlord smiled and immediately went out. 1)smile,微笑。注意与laugh(大笑)的区别。 2)immediately放在句首起到强调作用,说明店主很清楚发生这种事情一般都是怎么回事。 3)go out,出去。   In a few minutes, he returned with my bag   and gave it back to me.   1)in a few minutes,几分钟之后。 2)return,回来、归还。 3)give ... back to sb.,把某物还给某人。   I"m very sorry," he said. "My dog had taken it into the garden.   He often does this!"   1)可提问学生为什么句中的take要用过去完成时(因为店主针对的是他自己把包还给动作的过去时间来讲,而狗是在此之前把包叼进花园里的,是过去的过去)。 2)可提问学生为什么最后一句的动词do要用一般现在时does(因为often)。   三、读写重点   可多训练教材第82页难点部分的有关give的短语。

Lesson 8 - 抽样分布与中心极限定理

请注意我们本来要找的是什么,我们要找的是 特定样本在样本均值分布的什么位置 ,不仅仅针对是这个简单的总体更是针对庞大的总体。 现在可以找到了因为现在我们知道对于均值分布,其中 每个均值都是样本量为 n 的均值 ,该分布的标准偏差就等于总体标准偏差除以平方根 n,这就叫做 中心极限定理 。 它不仅适用于这些简单的总体,更是适用于任何总体。 正是因为中心极限定理,我们的总体可以是任何形状 。 假设我们从中抽取一个样本并计算出均值,然后再抽取出一个样本并计算出均值,持续这么操作。 如果 画出均值分布图的话,形状会是相对正态的 ,其中标准偏差等于总体标准偏差除以样本量的平方根我们一直都叫它 SE In this section, we learned about how Inferential Statistics differs from Descriptive Statistics . Descriptive statistics is about describing our collected data . Inferential Statistics is about using our collected data to draw conclusions to a larger population . We looked at specific examples that allowed us to identify the In this section, we learned about how Inferential Statistics differs from Descriptive Statistics. Descriptive statistics is about describing our collected data using the measures discussed throughout this lesson: measures of center, measures of spread, shape of our distribution, and outliers. We can also use plots of our data to gain a better understanding. Inferential Statistics is about using our collected data to draw conclusions to a larger population . Performing inferential statistics well requires that we take a sample that accurately represents our population of interest. A common way to collect data is via a survey. However, surveys may be extremely biased depending on the types of questions that are asked, and the way the questions are asked. This is a topic you should think about when tackling the the first project. We looked at specific examples that allowed us to identify the We have already learned some really valuable ideas about sampling distributions: First, we have defined sampling distributions as the distribution of a statistic. This is fundamental - I cannot stress the importance of this idea. We simulated the creation of sampling distributions in the previous ipython notebook for samples of size 5 and size 20, which is something you will do more than once in the upcoming concepts and lessons. 选择不同的组合统计量会不相同 如果选择所有的组合将会出现下面的结果 如果将不同的组合产生的统计量进行绘图可得 以上的分布就为抽样分布 Second, we found out some interesting ideas about sampling distributions that will be iterated later in this lesson as well. We found that for proportions (and also means, as proportions are just the mean of 1 and 0 values), the following characteristics hold. 练习 The rest of this lesson will reinforce some of these ideas that you saw at work in this notebook, but you are already being introduced to some big ideas that will continue to show up again and again. As you saw in this video, we commonly use Greek symbols as parameters and lowercase letters as the corresponding statistics. Sometimes in the literature, you might also see the same Greek symbols with a "hat" to represent that this is an estimate of the corresponding parameter. Below is a table that provides some of the most common parameters and corresponding statistics, as shown in the video. Remember that all parameters pertain to a population, while all statistics pertain to a sample. 总体参数不会因样本的不同发生变化, 只有统计量会因样本的不同而不同. Two important mathematical theorems for working with sampling distributions include: The Law of Large Numbers says that as our sample size increases, the sample mean gets closer to the population mean , but how did we determine that the sample mean would estimate a population mean in the first place? How would we identify another relationship between parameter and statistic like this in the future? Three of the most common ways are with the following estimation techniques: Though these are beyond the scope of what is covered in this course, these are techniques that should be well understood for Data Scientist"s that may need to understand how to estimate some value that isn"t as common as a mean or variance. Using one of these methods to determine a "best estimate", would be a necessity. The Central Limit Theorem states that with a large enough sample size the sampling distribution of the mean will be normally distributed. The Central Limit Theorem actually applies for these well known statistics: And it applies for additional statistics, but it doesn"t apply for all statistics! . You will see more on this towards the end of this lesson. In the previous example, you saw how the Central Limit Theorem applies to the sample mean of 100 draws from a right-skewed distribution. However, it did not apply to a sample size of 3 draws from this same distribution.( 并不适用所有的抽样分布) 适用于: 不适用于: In the next concepts, you will see that the with large sample sizes the sampling distribution of certain statistics will never become normally distributed. So how do we know which statistics will follow normal distributions, and which will not? So, you might be wondering already why is the Central Limit Theorem such a big deal? In our new age of computers, it probably isn"t as big of a deal, but more on this coming up soon! Bootstrapping is sampling with replacement.(已放回方式进行抽样, 也就是说被抽取的个体有可能在下一次接着被抽到, 也有可能被一直抽到, 但是这个可能性非常小)Using random.choice in python actually samples in this way. Where the probability of any number in our set stays the same regardless of how many times it has been chosen. Flipping a coin and rolling a die are kind of like bootstrap sampling as well, as rolling a 6 in one scenario doesn"t mean that 6 is less likely later. 在推论统计学中, 使用统计量去推断总体参数, 假设我们让样本当作一个总体, 上图中的21个杯子, 虽然只有总体的一个样本, 但是假设它们是总体, 可以从中对其进行自助抽样, 在一个样本和另一个样本之间, 喝咖啡的人之间比例有什么变化. 从上图中可以看出, 两次的均值不同, 因为第二次虽然还是21个样本数, 但是每一个个体都是从新从原始的21个个体中抽取. You actually have been bootstrapping to create sampling distributions in earlier parts of this lesson, but this can be extended to a bigger idea. It turns out, we can do a pretty good job of finding out where a parameter is by using a sampling distribution created from bootstrapping from only a sample. This will be covered in depth in the next lessons. Three of the most common ways are with the following estimation techniques for finding "good statistics" are as shown previously: Though these are beyond the scope of what is covered in this course, these are techniques that should be well understood for data scientists who may need to understand how to estimate some value that isn"t as common as a mean or variance. Using one of these methods to determine a "best estimate" would be a necessity. Two helpful links: In this lesson, you have learned a ton! You learned: Sampling Distributions In this lesson you gained the fundamental ideas that will help you with the next two lessons by learning about sampling distributions and bootstrapping. These are going provide the basis for confidence intervals and hypothesis testing in the next two lessons.
