Until的详细用法总结

Until的详细用法总结 你们知道until用法吗?我们一起来学习学习吧,下面就和大家分享,来欣赏一下吧。 Until的用法 比较until和till 此两个连词意义相同。肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可以。正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。 肯定句: I slept until midnight. 我一直睡到半夜时醒了。 Wait till I call you. 等着我叫你。 (在肯定句中可用before代替Lets get in the wheat before the sun sets.) 否定句: She didnt arrive until 6 oclock.

她直到6点才到。 until 用法上的三个难点 一、 1. until用在肯定句,谓语动词通常是延续性动词,如stand, stay, talk, wait等,表示主句动作终止的时间。如: ③I waited until he cam e back.我一直等到他回来。 ④The war lasted until 1945.战争持续到1945年。 如果用在否定句,谓语动词通常是瞬间性动词,如open, start, leave, arrive, finish, stop等,强调主句动作开始的时间。如: ⑤I didnt leave the boy until his mother turned up.直到这孩子的母亲来,我才离开。 ⑥The noise of the street didnt stop until it wa s midnight.街上的噪音直到半夜才停止。 2.连词until引导的从句中谓语动词的时态 1)until后面的从句中不能用一般将来时,应该用一般现在时代替。所谓的“主将从现”。 He will stay here until his mother comes back.

until与not...until...及It is not until...that...的用法详解

1.until (即是介词又是连词)要区分开哪种情况是介词及连词 介词prep. 1.直到...时,到...为止 Will this fish keep until tomorrow? 这鱼能搁到明天吗? 2.(用于否定句)在...之前,直到...才 She didn't go to bed until eleven o'clock. 她直到十一点才上床睡觉。 连接词conj. 1.直到...时,到...为止 You can wait here until help comes.你可以在这里等,直到有人来帮你。 2.(用于否定句)在...以前,直到...才 She didn't go to bed until her daughter came back. 她一直等到女儿回来才去睡觉。 You can't leave until I come back.。直到我回来你才可以离开 ■“not…until””意思是:“直到……才……”表示在这个界限之前一直没有发生这个动作 ■“until””意思是:“直到……”表示这个动作一直延续到这个界限出现时。 ■将“not…until””句型翻译成了否定句,如上句:直到我回来你不可以离开×) ■wait、keep是延续性动词,所以用肯定形式;而go to bed、leave是非延续性动词,所以用否定形式。 ■用“until”还是“not…until”要看谓语动词是延续性还是非延续性动词 ■until用做连词时,要注意以下几点 not…until 到…才…”

■对not…until的强调结构为“It is / was not until…that…”虽然两者都有not进行了否定,但中文要译成肯定“直到……才……” ■It was not until yesterday that I noticed it. =I didn’t notice it until yesterday. 直到昨天我才注意到此事。 It was not until I saw Mary that I felt happy. =I didn’t feel happy until I saw Mary 直到见到玛丽我才高兴起来。 ■ ■ ■Not until…until It was _____ I went there _____ I began to know something about the matter. 直到我到那里我才了解那件事。 A. until; when B.until; that C.not until; that D.not when;that (正确为C) ①Not until the teacher came in did the students stop talking. 直到老师进来学生们才停止讲话。 ②Not until next week will the sports meet be held.直到下周才开运动会。 主句倒装时要注意以下几点: 1.主句倒装时注意主句中的谓语动词是is/are/am/was/were时,将此be动词提到主 2.句的主语前面; 3.主句中的谓语动词是实意动词,时态为现在/过去时,将do/does/did提前到主语前, 完成时将have/has/had提到主语前; 4.主句中的谓语由情态动词构成时,将情态动词如can/may/must/could等提到主句的主语前。 5.主句中时态为将来时,将will等提到主句中的主语前面。

Till能否用于句首

龙源期刊网 https://www.sodocs.net/doc/0e15833107.html, Till能否用于句首 作者:刘春丽 来源:《新课程·中旬》2013年第05期 摘要:在教学中为能充分准确地给学生展示语法until和till的用法,分别从教辅资料和网上教学视频中收集资料,却意外地在一知名学校的视频中发现不妥之处。为此,通过查阅其他教辅资料和观看多个网络视频后得出,某知名学校的教学视频有误,继而反省并警示自己须审慎对待教辅,教学应准确科学。 关键词:until/till;教学;句首 一、遇到的疑惑 最近的教学中遇到一个疑惑,即until和till谁能用于句首的 用法问题。我们用的是《百年学典·高中全程学习导与练》,关于这两个词的用法如下:till和until(till不可位于句首),在肯定句中,主句的谓语动词是延续性动词,而在否定句中,主句的谓语动词是瞬间性动词。如:He waited until/till his mother came back.(他一直等到他妈妈回来。)I didn’t go to bed until I finished my homework.(直到做完作业我才上床睡觉。)为了更好地呈现这一语法点,我利用网络在某视频教育频道教育列表下的考试辅导一栏里面找了些视频材料,其中在一个PPT里发现有疑问地方,此下为该视频的文字摘录: till可用于句首,而until通常不用于句首,通常用于句中。 e.g. I had heard nothing of what happened until you told me. ***“not...until”的四种不同句式 1.正常句式 We didn’t go home unt il we finished our homework. 2.Until在句首 Until we finished our homework,we didn’t go home. 解释:因为从句的位置可以放在主句前,所以a中的句子可改换成b中的句子,但改换后我们发现,until放在了句首的位置,因为until不能用于句首,所以这个句子是错的,解决办法是把主句中的否定词not提前到until前面,所以我们有下面这个句子: Not until we finished our homework did we go home.

2021届新高考英语语法讲义时间状语从句中until till用法知识点整理总结

2021届新高考语法讲义时间状语从句中until till用法知识点整理总结 今天我们继续学习时间状语从句的引导词until和till,以及具有怀旧意味的not…until结构的用法。 01 until/till用法概述 until和till都是“直到…”的意思,从字面上来看,二者都表示一个动作持续到一定时候。那么与二者连用的动词都必须是延续性的。 之前我们讲过,延续性有两种情况:一是动词本身是延续的;二是短暂性动词的否定状态。 如: He stayed in her room until/till midnight. 他在她的房间待到了深夜。 He didn't leave her room until/till midnight. 他直至深夜才从她的房间离开。 02 在肯定句中 until/till在肯定句中表示“直到…”,主句的动词必须是延续性动词,表示一个动作直到某个时间才停下来。如: You may stay here until/till the rain stops. 您可以在雨停之后在离开。

The child remained silent until/till the movie ended. 电影结束之前,那个孩子都很安静。 03 在否定句中(not…until/till结构) 我们一般将n o t…u n ti l/ti l l结构翻译成“直到…才”。句子中必须要用短暂性动词,这样用n o t进行否定后就变成了延续性动词。如: T h e ch i l d di dn't f a l l a sl e e p u n ti l h i s m o th e r ca m e b a c k. 妈妈回来后,那个小孩才睡着。 此外,当not提前时,要用倒装结构,如: Not until you mentioned it, did I have any idea of it. 直到你提到它,我才想到它。 04 until和till的小区别 until和till基本可以换用,但until可以位于句首,till则不可以。如:Until he told me the news, I had no idea of it. 直到他告诉我,我都不知道这个消息。

until用法归纳

使用注意事项: ◇注意事项一 until用于肯定句中,表示主句的动作一直持续到从句动作发生或状态出现时为止。一般可译为“……直到……为止”。在这种用法中,主句的谓语动词必须是持续动词(非瞬间动词),如live, wait , last, love, like, stay, work, continue 等。 until用于否定句中,表示主句的动作在从句的动作发生之前尚未发生,或者说主句的动作在从句的动作发生之后才开始。一般可译为“直到……才”。 ◇注意事项二 until后面的从句中不能用一般将来时,应该用一般现在时代替。所谓的“主将从现”。 He will stay here until his mother comes back. They will study at the school until their parents come to take them home. ◇注意事项三(该考点为高中内容) till和until的意思基本相同,用法也基本一样,但until语气较重,多用于较正式的文体里。till多用于英式英语,until多用于美式英语;till不能用在句首,也不能用在not开头的短语或从句里,而until可以。在这种情况下应用倒装语序。 Until he came home, we knew the news. 在他到家之前,我们不知道这消息。Not until nine o’clock yesterday evening did we fi nish the work. 直到昨晚九点,我们才完成这项工作。 ◇注意事项四(该考点在初中阶段基本不涉及)

until用法

一、until ,till和not untill的区别 till / until在表达方式和意义上的特殊性:until是till的强调形式,但是它们表达的意义是相同的,都表示"直到某时"。不过,当主句是否定句时,它引出的意思是"直到(某时)(某动作)才(发生)" ,这时候常会出现"not until …"的结构,如果将"not until …"的结构放在句首,那么主句要写成倒装句。例如: He didn't go to sleep until 12 last night . 他昨晚直到十二点钟才睡觉。 They didn't realize their fault till we pointed it out to them . 直到我们向他们指出了他们的错误,他们才意识到。 Not until we pointed out their fault to them did they realize it . 直到我们向他们指出了他们的错误,他们才意识到。 但是,当主句是肯定句时,它引出的意思是"直到(某时某动作停止了)" 。例如: The students made much noise till the teacher came into the classroom . 直到老师走进教室学生们才停止了大声喧哗。 The young couple were very happy until they used up all their money . 那对年青夫妇直到花光了所有的钱才沮丧起来。 另外,until 可以放在句首而till则不行。我们可以说:Until they used up all their money, the young couple were very happy .我们却不可以说:Till they used up all their money, the young couple were very happy . 二、肯定与否定 1.肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。 2.否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可 以。 3.正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否 定式。 肯定句: I slept until midnight. 我一直睡到半夜时醒了。 Wait till I call you. 等着我叫你。 (在肯定句中可用before代替 Let's get in the wheat before the sun sets.)否定句:She didn't arrive until 6 o'clock. 她直到6点才到。Don't get off the bus until it has stopped. 公共汽车停稳后再下车。 I didn't manage to do it until you had explained how. 直到你教我后,我才会做。

until的用法

1、He is absent till/until now. 他到现在还没来 2、He didn't show up till/untill now. 他到现在才来 详解: till / until在表达方式和意义上的特殊性:until是till的强调形式,但是它们表达的意义是相同的,都表示"直到某时"。不过,当主句是否定句时,它引出的意思是"直到(某时)(某动作)才(发生)" ,这时候常会出现"not until …"的结构,如果将"not until …"的结构放在句首,那么主句要写成倒装句。例如: He didn't go to sleep until 12 last night . 他昨晚直到十二点钟才睡觉。 They didn't realize their fault till we pointed it out to them . 直到我们向他们指出了他们的错误,他们才意识到。 Not until we pointed out their fault to them did they realize it . 直到我们向他们指出了他们的错误,他们才意识到。 但是,当主句是肯定句时,它引出的意思是"直到(某时某动作停止了)" 。例如: The students made much noise till the teacher came into the classroom . 直到老师走进教室学生们才停止了大声喧哗。 The young couple were very happy until they used up all their money . 那对年青夫妇直到花光了所有的钱才沮丧起来。 另外,until 可以放在句首而till则不行。我们可以说:Until they used up all their money, the young couple were very happy .我们却不可以说:Till they used up all their money, the young couple were very happy . 此两个连词意义相同。肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可以。正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。 肯定句:

小知识点:not until的用法

Until和not until的用法以及until与till的区别Until既可以作介词(prep.)又可以作连词(conj.),意思就是说until后面既可以不接句子,又可以接句子。 till和until一般情况下两者可以互换,但是在强调句型中多用until。 并且要注意的是: 如果主句中的谓语动词是瞬时动词时,必须用否定形式; 如果主句中的谓语动词是延续性动词时,用肯定或否定形式都可以,但表达的意思不同。例如: 谓语动词是瞬时动词 I didn't go to bed until(till) my father came back.(否定) 直到我父亲回来我才上床睡觉。 It was not until the meeting was over that he began to teach me English.(否定) 直到散会之后他才开始教我英语。 谓语动词是延续性动词 I worked until he came back.(肯定) 我工作到他回来为止。 I didn't work until he came back.(否定) 他回来我这才开始工作。 Please wait until I arrived.(肯定) 在我到达之前请等我。 Until和till 英美国家的英语语法教师是这样来描述这两个字的分别的: Till是指直到某一特定事件发生的时候,而在那个时刻之后,该事情或状况仍将持续。 Until是指直到某一特定事件发生的时候,而讲话的人在自己心里认为,在那个时刻之后,该事情或该状况将中止(不怎么可能持续)。 实际上,很多人(包括外国人)写句子的时候不注意,也会犯混淆till until的错误的。 用在一些固定组合里的时候,till/until是不能替换的,from morning till night 就是一例。这也是它们的一种区别。 相同点: till / until在表达方式和意义上的特殊性:until是till的强调形式,但是它们表达的意义是相同的,都表示"直到某时"。 不过,当主句是否定句时,它引出的意思是"直到(某时)(某动作)才(发生)" ,这时候常会出现"not until …"的结构,如果将 "not until …"的结构放在句首,那么主句要写成倒装句。例如:

Till 和Untill 的用法区别

Till 和Untill 的用法区别 在很多情况下,这两个词是这可以互换使用的,也就是说,这两个词的意思非常相近。一般而言,till 用于肯定句,untill 用于否定句。但是,这两个词在意义上也是有细微差别的。 英美国家的英语语法教师是这样来描述这两个字的分别的: “Till” is used to mean the time up to a particular instance and the action can continue even after that. “Until” is used to mean the time up to a particular instance and the speaker has in mind that the action after this time does not almost happen. 翻译成中文来理解就是: Till是指直到某一特定事件发生的时候,而在那个时刻之后,该事情或状况仍将持续。 Until是指直到某一特定事件发生的时候,而讲话的人在自己心里认为,在那个时刻之后,该事情或该状况将中止(不怎么可能持续)。 这应该把一切都说得很明白了。 一、Till 用法示例: 1. People do not know the value of health till they lose it. 直到失去健康,人们才知道健康的可贵。 2. I'll wait till four o'clock. 我将等到四点钟。 3. We must stick to our task till it is finished. 我们必须继续工作, 直至做好为止。 4. Not till then did I realize the danger of the situation. 直到那个时候我才感到形势的危险。 5. Never put off till tomorrow what you can do today. 今日事今日毕。 6. The people next door play their radio from morning till night. 邻居从早到晚开着收音机。 7. The meeting adjourned till five o'clock. 会议延至五点召开。 8. Gee, I can hardly wait till it's dark. 哎呀,我简直等不到天黑了。 二、Until 用法示例

until的用法

Until的用法 until可用作介词或连词,意为“到……时候为止”、“到……时候才”或“在……时候以前不”。什么情况下表达什么意思,关键要看(主)句中的谓语动词是终止性动词还是延续性动词。 1. 如果(主)句中的谓语动词是终止性动词,应采用“... not ... until ...”结构,意为“……到……时候才……”。例如: You mustn’t eat anything until you see the doctor. 看过医生之后,你才能吃东西。 Don’t get off the bus until it has stopped. 车停稳了以后再下车。 2. 如果(主)句中的谓语动词是延续性动词,那么谓语动词用肯定式或否定式,它们所表达的意思有所不同。 1)如果谓语动词为肯定式,则until译为“到……时候为止”。例如: I watched TV until she came back. 我看电视一直看到她回来。 2)如果谓语动词为否定式,则until应译为“到……时候才”,即“在……以前不”。例如:I did not watch TV until she came back. (= I began to watch TV when/after she came back.) 直到她回来我才开始看电视。 3. 用终止性动词作谓语时,until既可以和not连用,又可以和never,nobody,nothing,few,little,seldom,hardly等含否定意义的词连用。例如: I had not seen him until 1990. (= I had never seen him until 1990.) 1990年以前我从未见过他。 Don’t put off until tomorrow what you can do today. (= Never put off what you can do today till tomorrow.) 今日事,今日毕。 4. 连词until引导的从句中谓语动词的时态。 1)主句的谓语动词为一般现在时或一般将来时时,until从句中的谓语动词为现在完成时,用来强调从句谓语动词表示的动作发生在主句谓语动词表示的动作之前。试比较: I won’t go to bed until I have finished my homework. 我要完成作业才睡觉。 2)主句中的谓语动词为一般过去时时,从句中的谓语动词为过去完成时,用来强调从句谓语动词的动作发生在主句谓语动词表示的动作之前。试比较: Li Lei didn’t come until the film had begun. 直到电影开演,李雷才来。 〔特别提醒〕till和until的意思基本相同,用法也基本一样,但until语气较重,多用于较正式的文体里。till多用于英式英语,until多用于美式英语;till不能用在句首,也不能用在not开头的短语或从句里,而until可以。例如: Until he came home,we knew the news. 在他到家之前,我们不知道这消息。 Not until nine o’clock yesterday evening did we finish the work. 直到昨晚九点,我们才完成这项工作。

until用法

until的用法 until的用法对初学英语者而言,因为常遇和常用,所以既是重点,也是难点,下面就对until的用法进行浅析。 ●until具有介词(prep.)(conj.) 当until作为介词时,后面跟名词。 He didn’t stop working until his death. 当until 作为连词时,后面引导一个时间状语从句。 He didn’t stop working until he died. ●难点1---当until作连词,引导时间状语从句。 时态根据语境不同,出现以下两种情况: 1)事情还未发生(仅表示一种打算)<>这时主句用一般将来时,until后的从句,要用一般现在时。 There will be a wonderful match tonight.I will watch it until it finishes.有时,在从句中还能用现在完成时代替一般将来时。 Don't get off the bus until it has stopped. 2)陈述过去发生过的事,那么主句与从句都用一般过去时。 Last night there was a wonderful match.I watched it until it finished.有时,陈述常发生的事,那么主句与从句都用一般现在时。 In the afternoon Jack reads books until his father comes back from the office. ●难点2---“until+某一时间点”谓语动词如果是瞬间动词,必须要用否定形式。例如:
