Grammar:过去进行时

  Step1:复习巩固、激情导入

  复习:现在进行时的构成、用法

  导入:复习了现在进行时之后,在此基础上我们将进一步学习本单元新的语法:过去进行时

  Step2:出示目标、明确任务

  1.掌握现在进行时的概念、结构、句式;

  2.灵活运用现在进行时;

  Step3:自主学习、合作探究

  过去进行时

  (一)定义

  过去进行时,是表示过去某个具体时刻正在进行的事情或动作。

  (二)结构

  was/were +doing (现在分词)

  (三)用法

  1、过去进行时表示过去某段时间内持续进行的动作或者事情。常用的时间状语this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while例如:

  We were watching TV from seven to nine last night.

  What was he researching all day last Sunday?

  My brother fell while he was riding his bicycle and hurt himself.

  It was raining when they left the station.

  When I got to the top of the mountain, the sun was shining.

  2. 过去进行时可以表示在过去某个时间点发生的事情。时间点可以用介词短语、副词或从句来表示。如:

  What was she doing at nine o'clock yesterday?

  When I saw him he was decorating his room.

  3. 在复合句中,如果主要动作和背景动作都是延续的或同时发生的,那么主从句的动词都可用过去进行时。例如:

  While he was waiting for the bus, he was reading a newspaper.

  他边等车边看报。(两个动作都是延续的)

  He was cleaning his car while I was cooking.

  他擦车时我在做饭。(两个动作同时进行)

  4. 通常不能用于过去进行时的动词主要有:agree, be, believe, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。例如:

  误:I was knowing the answer.

  正:I knew the answer. 我知道答案。

  误:I wasn't understanding him.

  正:I didn't understand him. 我不明白他的意思。

  典型例题:

  1) Mary ___ a dress when she cut her finger.

  A. made B. is making C. was making D. makes

  答案C. 割伤手指是已发生的事情,应用过去时。同时,when表时间的同时性,“玛丽在做衣服时”提供事情发生的背景,因此用过去进行时。

  2) As she ___ the newspaper, Granny ___ asleep.

  A. read; was falling B. was reading; fell C. was reading; was falling D. read;fell

  答案B.句中的as = when, while,意为“当……之时”。描述一件事发生的背景时,用过去进行;一个长动作发生的时候,另一个短动作发生。句意为 “在她看报纸时,奶奶睡着了。”句中的 fell (fall的过去时),是系动词,后跟形容词,如:fall sick。

  Step4:师生互动、展示提升

  考题1 As she ____the newspaper ,Granny ____ asleep .(95)

  A. read /was falling B .was reading /fell

  C. Was reading /was falling D. read/fell

  分析时间从句的动作长,而“入睡”动作短,故前者用过去进行时,而较短动词用一般过去时,选B

  考题2 Tom ___ into the house when no one ___ .

  A. slipped/was looking B. Had slipped /looked

  C. slipped/had looked D. was slipping /looked

  分析此题先要理解好when ,表“此时”,说明主句中slipped是较短行为,而look是较长行为的片断,即汤姆溜进房子,此时没人瞧见,故选A为正确。

  Step5:巩固练习、检测验收

  Exercise: Student Book P29 II:1-5
