八上 U3 知识点 一、过去进行时

表示:过去进行时表示过去某一时刻正在进行的动作,还可表示过去某阶段正进行的动作。 构成:主语 + was/were + doing 例如:



昨天7点到8点Tom 正在理发 练习:

1. 昨天晚上9点我正在图书馆学习。

___________________________________________ 2. 上一周的这个时候我正在做饭。

___________________________________________ 3. It was raining at 7 o’clock last night.(改为否定句) ___________________________________________

4. The boy was playing the piano when I came in.(改为一般疑问句) ___________________________________________

5. 划线提问) ___________________________________________

6. Mr.Green_____ (fly) a kite with his son at this time yesterday. 7.What______you_____(do) at ten o’clock yesterday morning? 二、when与while的区别 1. 两者都有“当??的时候”。when 既可指时间点有可指时间段,while只指时间段。When引导的动词既可以是延续性的也可以是非延续性的, 所以所引导的时间状语从句,主句用过去进行时,从句用一般过去式。如:

主句从句) 当UFO降落的时候我正在沿着大街散步。

2. While从句中的动词必须是延续性的,因此从句必须用过去进行时,主句可以是过去式也可以是过去进行时。如: 从句), the phone rang(主句). 当她正在学习的时候,电话铃响了。 练习:


1. 2. Don’t use your phone you are driving a car. 3. What were you doing Miss Wang come in? 4.We were watching TV the electricity was off. 5. 6. It snowed we arrived in Tokyo. 7. She left her hometown 用动词的适当形式填空。

1. I (write) a letter to my friend last night.

I (write) a letter to my friend at this time last night. 2. He (not do) his homework yesterday evening. He (not do) his homework at 9 yesterday evening. 3. We (play) the cards when someone knocked the door. 4. When I (come)in, he (do) between 8 and 10 yesterday morning? (make) a phone at that time.

8. He ( talk) with others when the teacher came in . 9. While my mother (see) them yesterday.

三、正确运用及区分下列词汇 1、follow的用法:

follow的形容词为following,意为“下列的”;常用于follow sb. to do sth.“跟随某人去干某事”。

典例:(1) What are you going to do in the _____(follow) week? (2) We followed Uncle Wang _____(visit) his company last week.

2、happen与take place的区别: happen与take place 都意为“发生”,但happen强调偶然性,take place强调计划性。happen还可用于happen to do sth.“碰巧干某事”sth. happen to sb.“某事发生在某人身上”。 典例:

(1) A traffic accident _____ to him yesterday.

A. happen B. happened C. took place D. take place (2) He happened ______(be) out when I called him yesterday. (3) What ______ ______ him yesterday? 他出什么事了? (4) Great changes _____ in our hometown in 2000.
