i have know _ack

我不认为以上句子是正确的。首先:have 和 know绝对不可能同时出现(一个句子两个谓语)。 其次,know(认识)是一瞬间的,我认识XXX已经有20年了只能说—— It"s been more than 20 years since I began to know david.

You have two brains,left brain has nothing right,right brain has nothing left!

总结起来就是:你个白痴!

i have no way

i have no way else的意思是:我没有别的办法; 但i don"t have other way的意思是:我没有其他的办法; 所以因该是写:i don"t have other way .

must与have to的区别

1. 强调重点不同两者都表示“必须”,但must侧重于说话者的主观看法,have to则侧重指客观需要,含有“不得不”或“被迫”之意。比较:You can borrow my car, but you must bring it back before ten. 你可以借我的汽车,但必须在10点以前开回来。I have lost my pen, so I have to buy one. 我的钢笔丢了,所以得去买一支。第一句用must,强调说话者的要求——你必须这样做,否则借车免谈;第二句用have to强调的是客观实际的需要——不得不买支新的,否则就没有笔用。2. 所用时态不同must 只有现在时一种形式(在宾语从句中可以表示过去),而 have to则有多种时态形式。如:He said she must go with me. 他说她必须同我一起去。We had to borrow a lot of money. 我们不得不要借一大笔钱。She has had to sell her house. 她不得不把房子卖掉。As a matter of fact, he"s having to sell his house. 事实上,他现在得卖房子了。除在宾语从句中表示过去可用 must 之外,其他表示过去的情况一般只用 had to。3. 非限定形式不同have to可以有分词、动名词、不定式等形式,而must则没有这些形式。如:I hate to have to get up in the morning. 我真不愿意早上非得起来不可。I don"t enjoy having to work with her. 我不喜欢必须与她共事。4. 动词搭配不同根据语义的需要,have to可以与情态动词搭配使用,而must本身作为情态动词,显然不能这样用。如:He may have to cancel the plan. 他可能需要打消这个计划。If we missed the train, we should have to wait an hour at the station. 假如我们赶不上这班火车,我们就得在车站再等一小时。5. 否定式的意义不同must 的否定式 mustn"t 意为“一定不要”“不允许”;而 have to 的否定式 don"t have to 意为“不必”(=needn"t)。比较(www.yygrammar.com):You mustn"t tell him about it. 你一定不要告诉他这件事。(这可能是秘密)You needn"t tell him about it. 你不必告诉他这件事。(他可能知道了)

must have been和mustbe的区别在哪儿?

must have been和must be的区别在have。因为本句是指对过去情况的推测,所以必须要用“情态动词+动词的完成式”。have在这里表示是动作已经完成。所以must have been是对过去的事实的肯定猜测,must be是对现在事实的肯定猜测。例句:Sorry I made such a fool of myself last night. I must have been drunk.翻译:对不起,我昨晚真是出丑了,我一定是喝醉了。must的用法1、must表示义务或强制,含意是“必须”“应当”;其否定结构表示“不许可”或“不应该”;用于一般疑问句时,表示征求对方的意见,其肯定答语用Yes, please或I"m afraid so,否定答语用needn"t或don"t have to; must在间接引语中表过去。2、must表示必然性,一般只用于肯定句中,有时表示“意愿”,带有感情色彩。

must be done和 must have done区别

must be done 意思是必须要做什么事 must have done 这是虚拟语气 必定做了…(表示对过去的推测

must have done的用法分过去和完成两种情况

must + 完成式(have done):推测过去所发生的事情和已经完成的动作: He must have arrived here last night. 他肯定是昨晚到达这里的. He must have had lunch. 他肯定吃过午饭了. must + 完成进行式(have been doing): 推测过去某一时刻正在进行的动作. It must have been raining at 8 yesterday morning.昨天早上六点钟时天肯定在下雨.

must have done和must be的区别?

musthavedone一定做过(表示过去做过的事对现在的影响)例:Youmusthavelied.你一定撒谎了。mustbe一定是表示一般的陈述例:Youmustbeastudent.你一定是个学生。PS:绝对权威!

must have done与must have been doing区别

动词后+ED和动词后+ING举个例子,I am interested in the book. The book is interesting.一个以人做主语,一个以物做主语。加ed是修饰人的,而加ing则是令人怎样的形容词。加ed成名词我没听说过。加ing是成动名词吧。说的不好你可以看下面的:ing形式做定语,意义上接近一个定语从句,表示一个正在进行的动作或表示一个主动的动作 如: China is a developing country=China is a country which is developing) ed式的则通常表示已发生的或已结束的动作,ing则表示正在发生的 如:boiled water开过了的水,白开水。 boiling water沸水 fallen leaves已落在地上的叶子 falling leaves正在下落的叶子 当然也有意义上的区别,在一些特定的词语上,如interesting和interested,exciting和excited这类词,ed就表示个人的感情而ing则表示物体的性质 如:interesting game好玩的游戏,ing表示游戏的性质——好玩 excited boy 兴奋的男孩,ed表示男孩的感情 除了这些特定的词,好多动词都可以加 ed,ing的,这并不局限,你可以参照英语人教版高一unit20 Humour(讲ing)和高二unit2(讲ed)

must have done的问题?

"Must have done"通常被称为虚拟完成时,表示过去某个时间发生的事情。在这种情况下,"must"表示说话者对事情发生的推测或假设,而"have done"则表示发生在过去的动作或事件。当使用"must have done"时,它通常暗示过去的时间,但并没有具体指明。因此,它可以用于现在完成时的某些情况下,例如:对于发生在过去、但没有具体时间表明的动作或事件,例如:"She must have finished her homework by now."(她现在肯定已经完成作业了。)对于对某个过去事件的推测或假设,例如:"He must have missed the train."(他肯定错过了那趟火车。)对于过去的某个可能性或猜测,例如:"They must have gone to the beach last weekend."(他们上个周末可能去了海滩。)需要注意的是,"must have done"并不总是等同于现在完成时,它只是现在完成时的一种用法,强调的是对过去事件的推测或假设。

英语you must have had many things怎么翻译?

must have done 与may( might) have done的区别

情态动词+havedone表示对过去事情的猜测。musthavedone一定做过mayhavedone可能做过,或许做过might与may意思相同,但可能性更小。

have to do和must的区别

must表示主观的义务和必要,主要用于肯定句和疑问句,意思为“必须……,得……,要……”;由must引起的疑问句,肯定回答要用must或haveto,否定回答要用needn"t或don"thaveto,意思是“不必”;must的否定形式mustn"t表示禁止,意思是“不能,不许”。 表示肯定的猜测,常用于肯定句中,意思为“一定是,必然……”。 注意must表示推断或猜测的几种情况: Your sister must be a doctor in this hospital.(现在的猜测) 你姐姐一定是这家医院的医生。

couldhave/mighthave/musthave/shouldhave都有什么区别

could/might have 可能有,语气较弱must have 必须有,语气很强should have 应该有,语气较强

下面这句话中“must have taken”是虚拟语气的用法么?“must”可以用作为构成虚拟语气的情态动词么?

不是。虚拟语气是说 想象。 判定/推断(estimation)和想象(imagination)不同, 是完全区分的概念, 判断是根据实际条件/正常情况来的,想象是根据虚假条件/极不可能的情况来的。那么这些 组合 都有 两种用法 表示 判断 或者 是想象。 我们可以用 情态动词+have+done 推断(could have,should have,might have,may have)/判定(would have,must have)过去的情况,此时依据的是 真实条件/正常情况。也可以用它们来进行 想象,此时依据的条件是 虚假的 if clause,without,或者是有转折的条件but..., 这时候就会和真实情况产生违背,因为只有不同 才会去想象。用你的话做个例子I thought you must have finished your home work last night.说这句话你是根据正常情况来判定的话,那他极大概率是完成了。此时叫判定(推断)又比如 10 years ago i would have been a little girl. (判定) 这明显是和事实符合的。如果是根据 虚假条件,转折条件,这就会和现实相违背。I thought you must have finished your home work last night if u had not been taken out by ur sister. 此时这就叫想象。当然并不是所有的话,都必须有 if 什么的,但是通过当时情景 可以知道 他说这句话是什么意思。 比如she would have apologized to u. 这句话,你打电话和对方说,表示你根据正常情况判断,她会跟你道歉,现实是 她很大概率确实道歉了,也有可能没道歉。但是 这个 “she”要是死了走丢了,此时你说这句话的含义是,你在想象一个虚假的条件she woulda apologized to u (if she were here/ if she were still alive). 这就是现实里 她并没道歉。其实我很不清楚 为什么很多人说话 用到 这些 组合的时候 总是会在乎 客观是不是真的发生了。完全没有关系

must have stolen 和must be stolen的区别?

主动和被动语态。情态动词后必须是动词原型,时态可以通过后面的结构体现,比如,进行时mustbeworking,mustbeplaying,完成时musthavefinished,被动式mustbestolen,完成时的被动表达musthavebeendone

英文 must/ must have/ must be 用法与中文意思差异

英文 must 用法 你都知道了吗?英文 must 的中文意思是指「必定、必须」的意思,must 有强烈的语气,后面接be 动词时变成must be ,意思是「必定是」的意思。同时,还可以变成 must have 或是must have been。本篇文章要教学所有must 的用法,赶快学起来吧! 下面教学英文 must/ must have/ must be 用法与中文意思差异。 内容目录 英文 must 用法 Must 用法1.must 必定、必须 Must 是 modal verb,也就是情态动词的意思。情态动词是一个学术词语,用来表达可能、意愿、必要的动词。 例: You must go home today. 你今天一定要回家。 例: I must get some sleep. 我必须睡一会儿了。 例: You must call Jenny today. 你今天要打给珍妮。 注意,如果must 后面接not 的话,代表不允许的意思喔。 例: You must not talk to Jenny today. 你今天不准跟珍妮说话。 例: You must not talk to strangers. 你不能跟陌生人聊天。 Must 用法2.must be 必定是 Must 后面的动词如果是be动词,那就变成了「必定是」的意思。 例: You must be Jenny"s mother. 你一定是珍妮的妈妈。 例: You must be hungry. 你一定饿了。 例: It must be tough for you. 对你来说肯定很艰难。 Must 用法3.must have+ p.p 用法 must have 后面接名词,意思是「一定有…」的意思。 例: You must have a car. 你一定有一辆车。 must have 是个很常见的句型,must have 后面常常加过去分词,变成 must have+ p.p。 例: You must have seen my mother before. 你一定以前见过我妈妈。 例: The door is open; someone must have been here. 门是开的,一定有人来过了。 例: I cannot find my watch; I must have lost it. 我找不到我的手表; 我一定丢了。 例: She must have been very tired. 她一定很累了。 其实must have+ p.p 的句型是must 加上完成式,也就是指过去发生了什么事情,是一种推测的语气,算是放马后炮的意思。 Must 用法4. is a must 必不可少的东西 你可能会很常听到这样的一句话,xxx is a must . 代表 xxx 是一件必不可少的东西啦!此时 must 当成名词,意思是「必需品、必备品」的意思。 例: Computer is a must for him. 电脑对他来说是必不可少的东西。 例: If you live in the country a car is a must. 如果你住在乡下,汽车是必不可少的。 5.英文 must 的其他用法 跟must有关的用法还有must-read跟must-have,must-have 是形容词,意思是指「必须要有的、必备的」,must-read 同样也是形容词,意思是指「必读的」。 例: This is a must-read book. 这是一本必读书。 例: The mobile phone is now a must-have device for children. 现在手机已成为儿童的必备设备。 另外,must-have 也可以直接当成名词,意思变成了「必备品」。 看完上面例句,你应该发现must- 开头的,其实就是「必…的」意思。相同的用法还有must-see或是must-do。 例: This is a must-see movie. 这是一部必看的电影。 must, must be, must be 用法, must have, must have 用法, must 中文, must 用法, 一定 英文, 必定 英文
