"ever since"和"since"都表示从过去的某个时间点到现在的持续。然而，它们之间有一些语义和用法上的差异。1. 强调："ever since"强调从过去某个事件开始直到现在持续不断的过程。它强调自那时以来一直持续发生的动作或状态。例如：I"ve been a fan of this band ever since I heard their first album."since"表示从某个过去时间点开始，到现在为止。它侧重于从某个时间点开始的概念，而不是整个过程的持续性。例如：I"ve been a fan of this band since 2010.2. 用法："ever since"通常用于强调从过去的某个事件开始到现在的持续性，可以用于现在完成进行时、现在完成时等时态。例如：He has been studying ever since he arrived.（自从他到了以后就一直在学习。）"since"可以用作连词，引导从句，表示自某个时间点开始；例如：It has been raining since this morning.（从今天早上开始就一直在下雨。）"since"还可以作为介词，后接某一具体时间点；例如：I haven"t seen her since last week.（自从上周以来我就没见过她了。）总之，"ever since"和"since"都表示从过去某个时间点到现在的持续过程，但"ever since"更强调持续性，而"since"则侧重于从某个时间点开始。在用法上，"since"可以作为连词和介词，而"ever since"主要用于强调过程。

由于二者均表示从某时间点开始，其动词的延续性及时态需进行认真的辨识：1、前者无需考虑动词的延续性还是短暂性，都作“自从，或从…起”讲：I have got a few opportunities to catch up with my classmates ever since I was ill.2、后者则需分以下三种情况加以区别：2.1 从句谓语动词为 be，且表成长某阶段或年龄时，则相当于 ever since：I have lived here (ever) since I was a child.2.2 从句谓语动词为延续动词，且为现在完成时，则无需介怀：She has never come to see me since I have lived in the city.2.3 从句谓语动词为延续动词，且时态是过去一般时，需在该动作结束后才能开始：I have made great progress since I was ill. （可不是自从生病了就进步了哈）3、最经典的语法例句，常见于小说：It is twenty years since I lived here.

完成时。ever since可作为副词，解释“此后”（就一直……），是完成时的标志。He fell ill at Christmas and has been ill ever since.他在圣诞节生病了此后就一直不适。 ever since释义：自从；从那时到现在；自…以后；从…起 ever since的用法 1.ever since的结构：(作为连词)=since完成时态----ever since+主+动词简单过去式 例：I have known him ever since he was a child. 他从小我就认识他了。这种用法同since差不多，不过ever since比since用得少。 再如：We have lived in Shanghai ever since we came to China.(自从我们来到中国之后就住在上海。) 2.以上所说的ever since作为连词。ever since也可作为副词，解释“此后”(就一直...)。例： 1)He fell ill at Christmas and has been ill ever since. 他在圣诞节生病了此后就一直不适。(has + be ill) 2)He left home last year and has been away ever since. 他去年离家走了，此后一直在外面。(has+be away) 3)He fell off his horse a week ago and has been in bed ever since. 一周前他从马背上跌下来，从那以后就一直躺在床上。 4)He went to Turkey in 1950 and has lived there ever since. 他在1950年去土耳其，此后就一直住在那里。

since 自……以来.表示动作从过去某一点时间一直延续到说话时间为止.主句中通常为延续性动词的现在完成时,since从句中一般用短暂性动词的一般过去时. It has been just a week since we arrived here. 我们到这儿刚刚一星期. ever since 从那时起直至现在,此后一直.表示说话者强调主句动作或状态持续时间长,语气比since强. Ever since they got married in 1950,they have lived happily. 自一九五零年结婚以来,他们一直生得很幸福.

一、意思不同1、ever since：自从，打…以后一直。2、since：从…以来。二、用法不同1、ever since：since用作副词表示“以前”时还可和long，ever连用。long since意为“好久以前”，not long since意为“就在不久前”，ever since意为“从那时起，此后一直”。三、侧重点不同1、ever since：ever since用在句尾时，所表达的时间应在上文中交待出来或是听话者知道的那个时间。2、since：since引导的状语从句的谓语动词是终止性的过去时，则从句表示的时间是“从动作开始的那一时刻起”

ever since 作为连词=since 完成时态---- ever since +主+动词简单过去式 例：I have known him ever since he was a child.他从小我就认识他了.这种用法同since 差不多,不过 ever since 比 since 用得少.再如：We have lived in Shanghai ever since we came to China.(自从我们来到中国之后就住在上海.) then本身是个过去的时间点,since then表示从那个时间点到现在的情况,一般是现在完成时.比如 I have not gone there since then.

ever since 的结构：(作为连词)=since 完成时态---- ever since +主+动词简单过去式。 ever since 作为连词。 ever since 也可作为副词，解释“此后”（就一直...） 扩展资料 　　例句： 　　He"s had a car ever since he was 18. 　　他从18岁起就有汽车了。 　　He"s been there ever since you left! 　　自从你离开，他一直都在那儿！ 　　He"s borne me a grudge ever since that day. 　　从那一天起他便对我怀恨在心。

一：1ever since you left me自从你离开了我 i"ve been try to hide the pain.我一直在掩饰内心的伤痛 用法,一般就是可用在句首,自从的意思.2主句用现在完成时,从句用一般过去时 eg. Ever since he moved to London, i haven`t seen him.ever since用在句尾时,所表达的时间应在上文中交待出来或是听话者知道的那个时间:"就从那时起,一直到现在" 二：since的用法主要有两点：一是表示“自从……以来”，二是表示“既然”之意。但如果只了解词的含义，而不了解其用法，在使用时就会造成错误。例如：I have not heard from him since I lived in Shanghai. 不少人会望文生义，将该句译为：“自从我住在上海以来，就再也没有收到他的信了。”而实际上这个句子的译文并非如此，那么正确的含义是什么呢？ 下面谈谈since作连词引导时间状语从句的用法。 一、若since引导的状语从句的谓语动词是终止性的过去时，则从句表示的时间是“从动作开始的那一时刻起”。如： He has studied very hard since he came to our school.自从他来到我们学校，他学习就非常努力。 We have been missing them since they left here自从他们离开这里，我们就一直很想念他们。 这是最常见的一种用法，此处不再多述。 二、若since引导的状语从句的谓语动词是持续性动词或表示状态的动词的过去时时，则从句表示的时间是“从那持续动作或状态结束时算起”。如： I haven"t heard any noise since I slept. Sleep 为持续性动词，sleep的动作结束时，即“醒来”时，这句应译为“我醒后还未听到任何声音”。 John is now with his parents in New York, it is already three years since he was a teacher约翰现在和父母一起住在纽约，他不当教师已经三年了。 本文开始出现的那个句子就可以译为“自从我离开上海，就再也没有收到他的信。”这种译法常被人们误用，我们不妨再多举几个例子看看： How long is it since you lived in Shanghai?你离开（没住在）上海多久了？ It is half a month since he was a League member.他退团（不当团员）半个月了。 It"s been quite some time since I was last in London我离开伦敦已很长时间了。 比较：He has written to me frequently since I was ill.自从我病愈以来，他屡次给我写信。（从句谓语为状态动词） He has written to me frequently since I fell ill.自从我生病以来，他就屡次给我写信。（从句谓语为终止性动词） 三、若since引导的状语从句的谓语为持续性动词的现在完成时，则表示动作和状态延续到现在（说话时刻），其表示的时间的起点应从动作发生之时算起。如： I haven"t heard from him since he has lived there。 这里has lived表示动作的持续性，时间的起点应从：“开始居住”时算起。因此此句可理解为“自从他（开始）住在那儿起，我就一直没收到他的来信”。 Since we have owned a car, we have gone camping every year。自从我们自己有了汽车，我们每年都去野营。 试比较：1. Since I"ve been at this school, we have had three headmasters.自从我到这所学校，我们已换了三个校长了。 Since I was at this school, they have had three headmasters.自从我离开这所学校，他们已换了三个校长了。 2.He has never been to see me since I have been ill. 自从我生病以来，他从未来看过我。 He has never been to see me since I was ill. 自从我病愈以来，他从未来看过我。 由此可见，since引导的从句持续动词的一般过去时和现在完成时所表示的意思恰好相反。换言之，前者以肯定的语法形式反映着否定的逻辑内容，而后者的形式与内容是一致的。 至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法，后者是口语说法。 应注意的是，在这种结构中，since引导的从句绝对不能用否定式的谓语动词来表示否定意义，下面两句都错了： It is a long time since he didn"t study English. It"s two months since you didn"t come to see me. 正确的说法为： It"s a long time since he studied English 他好久没学英语了。 You haven"t come to see me for two months. 你有两个月没来看我了

完成时。ever since可作为副词，解释“此后”（就一直……），是完成时的标志。He fell ill at Christmas and has been ill ever since.他在圣诞节生病了此后就一直不适。 扩展资料 　　ever since的用法： 　　1、ever since的结构：(作为连词)=since完成时态----ever since+主+动词简单过去式 　　例：I have known him ever since he was a child. 他从小我就认识他了。这种用法同since差不多，不过ever since比since用得少。 　　再如：We have lived in Shanghai ever since we came to China.(自从我们来到中国之后就住在上海。) 　　2、以上所说的ever since作为连词。ever since也可作为副词，解释“此后”(就一直...)。例： 　　1)He fell ill at Christmas and has been ill ever since. 他在圣诞节生病了此后就一直不适。(has + be ill) 　　2)He left home last year and has been away ever since. 他去年离家走了，此后一直在外面。(has+be away) 　　3)He fell off his horse a week ago and has been in bed ever since. 一周前他从马背上跌下来，从那以后就一直躺在床上。 　　4)He went to Turkey in 1950 and has lived there ever since. 他在1950年去土耳其，此后就一直住在那里。

ever since是从那时到现在 是since then哦 since then 是从那以后 祝你学习进步

ever since可以作介词、从属连词和副词。ever since+从句（用一般过去时），主句用现在完成时。ever since +名词，主句用现在完成时。主句（用现在完成时）+ ever since.

不一样，Ever since放句首是关系副词，引导从句；Ever since she was a little girl，she desired to be a moviestar.Ever since放句末只作副词；she has desired to be a moviestar ever since.表示一直的意思。

Ever since 可以译为“从那时起”；主句通常用“现在完成进行时”或“现在完成时”，从句一般用“一般过去时”。例如：He has been learning English ever since. 从那以后他一直在学英语。He has learned five languages since he went to Europe. 自从他去欧洲，他已经学了五种语言了。

ever since的读音为[ˈɛvər sɪns]。ever：永远；since：自从，自……以后；ever since表示一种时间上自……以来一直持续存在的状态或是某个动作的开始。常用于强调某个事件或者时间点，表达自那时候以来一直延续到现在的状态。I have been interested in photography ever since my college years.我自大学时代就对摄影感兴趣，一直持续到现在。ever since 和 since 的区别主要在时间上，ever since 表示从过去某个时间点一直持续到现在。而since仅仅表示从过去某个时间点开始，没有持续的时间限定。ever since 中的 ever 并不是表示“曾经”，因此不可将句子理解为“自从曾经……”。ever since可以翻译为“自从……以来一直……”或者“自从……之后一直……”，需要根据具体语境和含义来选择合适的翻译方式。扩展知识：英语（英语：English）是一种西日耳曼语支，最早被中世纪的英国使用，并因其广阔的殖民地而成为世界使用面积最广的语言。英国人的祖先盎格鲁部落是后来迁移到大不列颠岛地区的日耳曼部落之一，称为英格兰。这两个名字都来自波罗的海半岛的Anglia。该语言与弗里斯兰语和下撒克森语密切相关，其词汇受到其他日耳曼语系语言的影响，尤其是北欧语、北日耳曼语，并在很大程度上由拉丁文和法文撰写。

自...以来一直

意义不同。ever since强调从某个时间点开始一直持续，常用于表示某个动作或状态从过去一直延续到现在，since侧重于指从某个时间点以来，侧重于强调时间状语从句中的时间点。eversince通常用在口语中，而since更常见于正式的书面语中。此外，eversince和since还可以用于从一个事件或时间点开始计算时间的用法中。

ever since 自从……以来

由于二者均表示从某时间点开始，其动词的延续性及时态需进行认真的辨识：1、前者无需考虑动词的延续性还是短暂性，都作“自从，或从…起”讲：IhavegotafewopportunitiestocatchupwithmyclassmateseversinceIwasill.2、后者则需分以下三种情况加以区别：2.1从句谓语动词为be，且表成长某阶段或年龄时，则相当于eversince：Ihavelivedhere(ever)sinceIwasachild.2.2从句谓语动词为延续动词，且为现在完成时，则无需介怀：ShehasnevercometoseemesinceIhavelivedinthecity.2.3从句谓语动词为延续动词，且时态是过去一般时，需在该动作结束后才能开始：IhavemadegreatprogresssinceIwasill.（可不是自从生病了就进步了哈）3、最经典的语法例句，常见于小说：ItistwentyyearssinceIlivedhere.

ever since和since的区别为：指代不同、用法不同、侧重点不同。一、指代不同1、ever since:打··以后。2、since：从··以来。二、用法不同1、ever since:since用作连词作“自从···以来[以后或，现在］”解时，引导时间状语从句，在主句是现在完成时的情况下，如果since从句中谓语动词用一般过去时，则表示动作或状态的完成，计时的起点是动作或状态完成的那一时刻。2、since：since用作介词的意思是“从···以来，自从···之后”，其宾语常指过去的一个时间点，其含意通常指持续到说话时刻的动作或情况开始于什么时候。since之后常接名词、动名词作其宾语，since then意为“从那以后”。三、侧重点不同1、ever since：侧重于指从某个时间后一直持续。2、since：侧重于只是陈述从某时以后。

since作为介词后边接某一确定的时间点，主句谓语动词是持续性动词，常与现在完成时态、现在完成进行时态或过去完成时态连用。ever since后面可以不加任何东西，也可以加名词或者加从句。 since的用法 1、since+过去一个时间点（如具体的年、月、日期、钟点、1980, last month, half past six）。 I have been here since 1989. 2、since+一段时间+ago I have been here since five months ago. 3、since+从句 Great changes have taken place since you left. Considerable time has elapsed since we have been here. 4、It is+一段时间+since从句 It is two years since I became a postgraduate student. 5、用于句型“一段时间+has passed since+时间状语从句”中，译作“自从…以来, …（时间）已经过去了”。

eversince是“从那百时起，自那时以来”的意思。在句中，做介词或连词用均可以。要注意的度是，作连词时，所连接的主句与从句的谓语时态变化。如：IhaveknownhimeversinceIwasachild.我自孩提时代起就已经认识他了。主句用一般完成时态，从句用过去时态。知表示主语所发出的动作。Eleanorisalwaysapenny-pincheversinceshehasbeenyoung.埃莉诺从年轻时候起就一直是个非常吝啬的道人。主句用一般现在，从句用现在完成时态。表示主语的状态版或本质特性。I"vebeenonthegoeversinceeighto"clockthismorning.我从早晨八点钟起就一直忙个不停。在此句中eversince作介词权用，连接一个表时间的短语。供你参考，希望能帮到你。

ever since：自从……以来 表示动作从过去某一点时间一直延续到说话时间为止。 前面的主句用现在完成时，since后面的从句，用一般过去时。 例： I have known him ever since he was a child. 他从小我就认识他了。 We have lived in Shanghai ever since we came to China. 自从我们来到中国之后就住在上海。

由于二者均表示从某时间点开始，其动词的延续性及时态需进行认真的辨识：1、前者无需考虑动词的延续性还是短暂性，都作“自从，或从…起”讲：I have got a few opportunities to catch up with my classmates ever since I was ill.2、后者则必须这两个问题，分以下三种情况：2.1 从句谓语动词为 be，且表成长某阶段或年龄时，则相当于 ever since：I have lived here (ever) since I was a child.2.2 从句谓语动词为延续动词，且为现在完成时，则无需介怀：She has never come to see me since I have lived in the city.2.3 从句谓语动词为延续动词，且时态是过去一般时，需在该动作结束后才能开始：I have made great progress since I was ill. （可不是自从生病了就进步了哈）3、最经典的语法例句，常见于小说：It is twenty years since I lived here.

ince自……以来。表示动作从过去某一点时间一直延续到说话时间为止。主句中通常为延续性动词的现在完成时，since从句中一般用短暂性动词的一般过去时。It has been just a week since we arrived here.我们到这儿刚刚一星期。ever since 从那时起直至现在，此后一直。表示说话者强调主句动作或状态持续时间长，语气比since强。Ever since they got married in 1950, they have lived happily.自一九五零年结婚以来，他们一直生得很幸福。如果你认可我的回答，请及时点击采纳为【满意回答】按钮 手机提问者在客户端右上角评价点“满意”即可。 你的采纳是我前进的动力! 如还有新的问题，请另外向我求助，答题不易，谢谢支持……

ever since引导时间状语从句，主语用现在完成时,从句一般过去时； 用表示时间的连词连接一个句子作状语，这样的主从复合句就是时间状语从句。连接时间状语从句的连接词有：when, until, since...... 这里要注意一点的是，如果主句是一般将来时，从句只能用一般现在时表示将来意义。 扩展资料 　　He"s been in the doldrums ever since she left him. 　　自从她离开他以来，他一直很消沉。 　　He"s borne me a grudge ever since that day. 　　从那一天起他便对我怀恨在心。 　　I was bitten by a dog once and I"ve been afraid of them ever since. 　　我曾被狗咬过，自那以后就一直害怕狗。 　　He"s been there ever since you left! 　　自从你离开后他就一直在那里！

自从。。。以来

ever since 和since then 在用于完成时的句子里的时候基本上是可以换用的，而且意思也基本相同，都是“从那时起”

ever since常与现在完成时态连用如They have lived in the city ever since last year.自从去年以来，他们就住在这个城市。

"ever since"和"since"都表示从过去的某个时间点到现在的持续。然而，它们之间有一些语义和用法上的差异。1. 强调："ever since"强调从过去某个事件开始直到现在持续不断的过程。它强调自那时以来一直持续发生的动作或状态。例如：I"ve been a fan of this band ever since I heard their first album."since"表示从某个过去时间点开始，到现在为止。它侧重于从某个时间点开始的概念，而不是整个过程的持续性。例如：I"ve been a fan of this band since 2010.2. 用法："ever since"通常用于强调从过去的某个事件开始到现在的持续性，可以用于现在完成进行时、现在完成时等时态。例如：He has been studying ever since he arrived.（自从他到了以后就一直在学习。）"since"可以用作连词，引导从句，表示自某个时间点开始；例如：It has been raining since this morning.（从今天早上开始就一直在下雨。）"since"还可以作为介词，后接某一具体时间点；例如：I haven"t seen her since last week.（自从上周以来我就没见过她了。）总之，"ever since"和"since"都表示从过去某个时间点到现在的持续过程，但"ever since"更强调持续性，而"since"则侧重于从某个时间点开始。在用法上，"since"可以作为连词和介词，而"ever since"主要用于强调过程。

ever since是“从那时起，自那时以来 ”的意思。在句中，做介词或连词用均可以。要注意的是，作连词时，所连接的主句与从句的谓语时态变化。如：I have known him ever since I was a child. 我自孩提时代起就已经认识他了。 主句用一般完成时态，从句用过去时态。表示主语所发出的动作。 Eleanor is always a penny-pinch ever since she has been young. 埃莉诺从年轻时候起就一直是个非常吝啬的人。 主句用一般现在，从句用现在完成时态。表示主语的状态或本质特性。 I"ve been on the go ever since eight o"clock this morning. 我从早晨八点钟起就一直忙个不停。 在此句中ever since作介词用，连接一个表时间的短语。 供你参考，希望能帮到你。

用法不同1、ever since：since用作连词作“自从…以来〔以后或,现在〕”解时，引导时间状语从句，在主句是现在完成时的情况下，如果since从句中谓语动词用一般过去时，则表示动作或状态的完成，计时的起点是动作或状态完成的那一时刻。2、since：since用作介词的意思是“从…以来，自从…之后”，其宾语常指过去的一个时间点，其含意通常指持续到说话时刻的动作或情况开始于什么时候。since之后常接名词、动名词作其宾语，sincethen意为“从那以后”。

People"s opinions are always different when they talk about job-hopping. Those who never change their job throughout their life maintain that they have accumulated enough experience to work smoothly and efficiently, so what"s the point in changing it and taking another job? They also firmly believe that anyone who wants to excel in his specialty has to work hard on the same post for years to acquire the required skill and knowledge. However, many others hold just the opposite view. On the one hand, they believe that if the present job can offer neither satisfactory working conditions nor future opportunities, they will not hesitate a moment to leave. On the other hand, they hold that life is but once and job-hopping can provide rich and exciting experiences. My own opinion is that job-hopping, in this fast-changing era of information, has become more than common and acceptable. If we want to keep pace with the times, we have to change for the faster, the higher and the stronger. If life is a journey, we have nothing to regret so long as we put meaning into it. So why not make a change?

miss意思是思念 想念，错过，失去。这句话可以翻译为我想你，或者我错过你了。

I"m Missing You和I miss you的区别为：意思不同、用法不同、侧重点不同。一、意思不同1、I"m Missing You：我想你了。2、I miss you：我想你，思念。二、用法不同1、I"m Missing You：miss的基本意思是没能达到某人的既定目标，可以表示“没打中”“没猜中”“没到手”“没拿到”“没赶上”“没看到”“达不到标准”“不守约”“不尽义务”“发觉不在”“惦念”“避免”“失败”等。2、I miss you：miss既可用作不及物动词，也可用作及物动词。用作及物动词时，可接名词、代词、动名词作宾语。miss还可表示渴望做到而未做到或无法做到，这时常接动名词作宾语。三、侧重点不同1、I"m Missing You：是现在进行时，表示正在发生。2、I miss you：是一般现在时，表示这一状态。

你的意思是∫e^x cose^x dx么那么凑微分即可得到∫cose^x d(e^x)再积分即sin(e^x)+c，c为常数显然选择c选项
