It引导的时间状语从句总结与练习

高考It +be+ 时间+ 从句”结构 总结一 在“It +be+ 时间+ 从句”结构中,引导从句的从属连词有before, that, since, until (till ), when 等。这一结构是近几年高考常考的知识点,现将它们的用法小结如下: 一、It +be (not )+ 时间段+before 从句。 其中的主句是肯定式时,意为“过多长时间才……”;主句是否定式时,意为“没过多久就……”。例如: 1. It was not long before the whole country rose and drove the Austrian soldiers from their homeland. 不久,全国人民便奋起反抗,把奥地利军队从他们的国土上赶了出去。 2. It may be five or six years before the new medicine is tested on human beings. 要过五六年时间这种新药才能在人身上做试验。 3. It was two months before he designed the bridge. 过了两个月,他设计出了这座桥梁。 二、It +will be (was )+ 时间段+until 从句 若主句中用一般将来时,则从句中用一般现在时,意思是从现在起到从句中谓语动词表示的动作发生时还有多长时间;若主句中用一般过去时,则从句中也用一般过去时,意思是从过去某一时间起到从句中谓语动词表示的动作发生还有多长时间。例如: 1. It will be ten days until my birthday comes. 到我生日还有十天。 2. It was only five minutes until her husband came back from work. 当时离她丈夫下班只有五分钟了。 注意:结构“一”与结构“二”在肯定句中几乎可以通用。但是,若从句中谓语动词表示的将来动作一定或预期肯定会发生,则多用until 引导从句;若从句中谓语动词表示的将来动作在客观上并非一定要发生时,则多用before 引导从句。 三、It +is / has been (was )+ 时间段+since 从句 在这一结构中,主句常用一般现在时、现在完成时或一般过去时。如果since 引导的状语从句中的谓语动词为非延续性动词,则表示“自从状语从句中的动作发生以后,时间过不了多久”。例如: 1. It is two years since Jim came to China. 吉姆来中国两年了。 2. It has been three years since they got married. 他们结婚已经三年了。 如果since 从句中的谓语动词为延续性动词,则表示“自从从句谓语动词表示的动作结束以来,时间已过了多久”。例如: 3. It is / has been a year since he smoked. 他戒烟已经一年了。 四、It +is / was + 时间点+when 从句 在这一结构中,时间之前没有介词,从句为when 引导的时间状语从句。从句常用一般过去时,意为“当某事发生时,时间是……”。例如: 1. It was October 1st, 1949 when the People's Republic of China was founded. 中华人民共和国成立于1949 年10 月1 日。 2. What time was it when you got to school 你几点到的学校。 五. It is /was + 时间状语+that 从句

时间状语从句最全总结(初中)

时间状语从句 一. 概念:在复合句中,由时间连接词引导的状语从句叫做时间状语从句。 二.种类: 1.由when, while, as引导的时间状语从句。 (1).when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。动作既可和主句的动作同时发生又可在主句的动作之前或之后发生,并且when有时表示“就在那时”。 When she came in, I stopped eating.她进来时,我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当我住在农村时,我常常为他担水。(延续性的动词) (2)while强调主句的动作与从句的动作同时持续地进行,用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词,或者主句的动作发生在从句动作的进行过程中,主句中的谓语动词通常是非延续性动词。并且while有时还可以表示对比While my wife was reading the newspaper, I was watching TV. I met her while I was at school. I like playing football while you like playing basketball. (3)as引导时间状语从句时表示“当……时,一边……一边……”,侧重表示两个动作同时发生(包括一个主语同时进行两个动作),或者一种动作随着另一种动作的变化而变化。He jumps as he goes along. 他边走边跳。 As we was going out, it began to snow.当我们出门时,开始下雪了。(as强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间) 2.由before和after引导的时间状语从句。 before引导的时间状语从句表示主句动作发生在从句动作之前。从句不用否定的谓语形式。从句位于主句之后时,before有时译成“才;就”。还要注意主句和从句的时间关系。当主句用将来时,从句总是用现在时;从句用过去时,则主句多用过去完成时,以此来体现动作发生的先后顺序。 after表示主句动作发生在从句动作之后,主句和从句的时间关系正好与before相反。如:It will be four days before they come back.他们要过四天才能回来。 My father had left for Canada just before the letter arrived. 我父亲恰好在信到达之前去加拿大了。 After we had finished the work, we went home.完成工作之后,我们回家了。 3.由till或until引导的时间状语从句。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。till不可以用在句首,而until可以放在句首。 I didn't go to bed until(till) my father came back.直到我父亲回来我才 上床睡觉。 I worked until he came back.我工作到他回来为止。 I didn't work until he came back.他回来我这才开始工作。 4.由since引导的时间状语从句。“自从……以来”,或“自从……以后”, since引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。主句通常用现在完成时态,从句谓语动词用一般过去时,。但在It is +时间+since从句的句型中,主句多用一般现在时。 I have been in Beijing since you left. 自从你离开以来,我一直在北京了。

初中英语知识点总结:时间状语从句

在复合句中,由时间连接词引导的状语从句叫做时间状语从句。时间状语从句通常由when, while, as,after,before,since,until等词引导。 一、时间状语从句种类 1、引导的从句表示主从句的动作同时发生,或从句的动作在主句之前。when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。例如: When she came in, I stopped eating.她进来时,我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him.当我住在农村时,我常常为他担水。(延续性的动词) We were about to leave when he came in.我们就要离开,就在那时他进来了。 2、While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。例如:While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词,was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。(对比) 3、As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生;as也可以强调“一先一后。例如:We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”)As we was going out, it began to snow.当我们出门时,开始下雪了。(as强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间) 4、由before和after引导的时间状语从句,表示两个动作一前一后发生。 例如:It will be four days before they come back. 他们要过四天才能回来。 After you think it over, please let me know what you decide.你仔细考虑过以后,告诉我你是怎样决定的。 5、由till或until引导的时间状语从句。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。till不可以用在句首,而until可以放在句首。例如: I didn't go to bed until(till)my father came back.直到我父亲回来我才上床睡觉。 I worked until he came back.我工作到他回来为止。 6、由since引导的时间状语从句表示“自从……以来”。 I have been in Beijing since you left. 自从你离开以来,我一直在北京了。 7、由as soon as引导的时间状语从句表示“一……就”。例如: As soon as I reach Canada, I will ring you up. 我一到加拿大,就给你来电话。 二、时态问题 在状语从句中,有“主将从现”的规定,即主句用一般将来时,从句用一般现在时表示将来时。例句:I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。(这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,决不可用will arrive) 常见考法 对于时间状语从句的考查,多以单选和完形填空的形式,从连词的意义角度让大家选择连词,或从时态的角度设题,考查学生灵活运用的能力。 典型例题:I'm sure he will jump up when he the good news. A . know B will know C. knows D knowing 解析:本题考查学生时间状语从句的时态问题。时间状语从句中,主句若是一般将来时,从句应用一般现在时表示将来时。从句的主语是单三人称,所以排除A 。
