时间原因条件状语从句
掌门1对1教育高中英语 时间、原因、条件状语从句 一．when, while 和as 引导时间状语从句的区别用法（一）when 的用法when 从句的A事件，相当于另一个事件B发生的时间点。（也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，）所以when 多数情况下用的是一般过去时，则不用正在进行时。（口头练习） When I got to the airport, the guests had left. Why do you want a new job when you have got such a good one already? (二)while 的用法 while 从句的侧重点在于描述动作正在发生的状态，（它的意思是：当while 事件正在发生的时候，另一件事如何如何。）所以，while 从句一般用的是正在进行时。而另一件事的状态根据具体情况而定。（口头练习） 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看，while 表示的是一段时间，是一个过程。 趁热打铁。Strike while the iron is hot.（这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。） (三)as 的用法 as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。as 从句用的一般不用正在进行时，而只是一般过去时。可以翻译成“边……边……”。（口头练习） As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，常常翻译成“随着……”之意。 1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。 2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加，大气越来越稀薄。（少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边，边哭边叫喊。）
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

初中时间状语从句语法及练习
英语时间状语从句讲解 （一）when, while 和as 引导时间状语从句的用法 一、when 的用法 如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。 1. When he was a child he was always trying out new ideas. 3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ 4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。 when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，则不用正在进行时。因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。这种说法也可以参照。 实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。例如： 2. When he had finished his homework, he took a short rest. 3. Why do you want a new job when you have got such a good one already? 二、while 的用法 相比于when 来说，while 从句的侧重点就不一样了。while 从句的侧重点在于描述动作正在发生的状态，它的意思是：当while 事件正在发生的时候，另一件事如何如何。所以，while 从句一般用的是正在进行时。而另一件事的状态没有硬性的要求，根据具体情况而定。例如： 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin Tao came to see him. 3. While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。 从时间的角度来看，while 表示的是一段时间，是一个过程。这是while 的侧重点。因此，如果含有“一段时间”的含义的时候，就可以用while。 6. Strike while the iron is hot. 趁热打铁。 这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。 再例： —I'm going to the post office. —While you're there, can you get me some stamps? 三、as 的用法 as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。但与while 从句不同的是，as 从句用的一般不用正在进行时，而只是一般过去时。as 从句一般可以翻译成“边……边……”。例如： 1. As my mother sang those old songs, tears ran down her cheeks. 2. The students took notes as they listened. 学生们边听课边做笔记。 3. As we talked on, he got more and more excited. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，不像while 从句有强调while 动作本身的意思。因此，as 常常翻译成“随着……”之意。 例如： 1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。
