【归纳总结】

在复合句中充当时间状语的从句叫时间状语从句,它用来说明主句动作发生的时间。时间状语从句通常由when, while, before, after, since, till/until, as soon as, whenever等连词引导。本期我们先学习由when, while, beforeafter引导的时间状语从句。

when/while引导的时间状语从句

whenwhile都可表达……之意,但两者在用法上有所不同:

when引导的时间状语从句中的谓语动词既可以是瞬间动词,也可以是延续性动词。如:

I will tell you about that thing when I meet you. 我见到你的时候会告诉你那件事情的。

When I was in high school, I was always a top student in my class. 我上高中时,一直是班里的尖子生。

while引导的时间状语从句中的谓语动词通常是延续性动词。主从句的动作一般同时发生。如:

Mum was preparing for dinner while I was cleaning the room. 我打扫房间的时候妈妈在准备晚饭。

before/after引导的时间状语从句

before意为……after意为……。如:

Write the phone number down on a piece of paper before you forget it. 在你忘记这个电话号码前把它写在一张纸上。

I will call you after I hear from Jack. 我收到杰克的信后会打电话给你。

注意:

当主句和从句的主语一致时,可以省略从句中的主语,构成when/while/before/after + V-ing结构。如:

Don’t leave the door of the kitchen open while   (you are) cooking. 你做饭的时候别开着厨房门。

Before entering the room, you should take off   your shoes. 进屋之前你应该脱掉鞋子。

          D. arrives

. 同义句转换。每空一词。

Miss Yang asks about my studies    she meets me.

  6. The boys ran out of the classroom just at the time the bell rang.

      The boys ran out of the classroom            the bell rang.

Key:

1-4 BCAD                   

5. whenever                 

6. as soon as

【归纳总结】

since, till/until, as soon aswhenever引导的时间状语从句。

sincetill/until引导的时间状语从句

since意为自从……以来,一般情况下,从句中的谓语动词用一般过去时,主句中的谓语动词用现在完成时。如:

Jack has made a lot of friends since he went to junior high. 自从上初中以来杰克已经交了很多朋友。

till/until意为直到……时;到……为止,表示动作或状态一直持续到某一时刻。用在句中时两者常常可以互换。但在句首时,通常用until。如:

Until 2016, my uncle lived in Canada. 2016年为止,我叔叔一直住在加拿大。

当表示过去情况时,主从句均用一般过去时;当表示将来情况时,主句用一般将来时,从句常用一般现在时。如:

Millie listened to the radio till/until she fell asleep. 米莉听广播一直到睡着。

Take it easy, Tony. Your aunt will wait for you at the airport until/till she meets you. 放心吧,托尼!你阿姨会一直在机场等你,直到她接到你。

当主句中的谓语动词是瞬间动词时,必须用否定形式,即not … until结构,意为直到…………”。如:

I won’t give you this toy until my mother buys me a new one. 直到我妈妈给我买一个新玩具我才会把这个给你。

as soon aswhenever引导的时间状语从句

as soon as意为……,强调主句的动作紧跟着从句的动作发生。如果主句用一般将来时,从句常用一般现在时。如:

I’ll send you an email as soon as I finish the work. 我一完工就给你发邮件。

whenever意为每当;任何时候,相当于every time。如:

My parents are by me whenever I need help. 每当我需要帮助的时候,我的父母都在我身边。
