Step2 Grammar
（一）过去进行时
1.含义：表示过去的某一时刻或某一时间内正在进行或发生的动作。
2.构成：was/were+v-ing。
3.标志：at that time, this time yesterday, all the evening, from 8:00 to 10:00yesterday, just then, at nine yesterday, when等表示明确有具体的时间状语。eg：
I was doing my homework at this time yesterday.
What was Tom doing at ten yesterday.
I was eating dinner when the phone rang.
4.具体的句型：
(1)肯定句：主语+was/were+v-ing eg：
They were having a meeting that time.
(2)否定句：主语+was not(wasn’t)/were not(weren’t) +v-ing
上句改写为：They were having a meeting that time._____________________
(3)一般疑问句式：Was/Were +主语+v-ing？
肯定回答：Yes，…was/were.
否定回答：No，…wasn’t/weren’t.
Eg：Was she reading a book when the teacher came in?
Yes,she was. / No, she wasn’t.
(二)when与while用法
1.when是“当……时候”，相当于at that time,既可以表示某一时刻又可以表示某一段时间，所以when引导的时间状语从句动词既可以是延续性的，又可以是非延续性的。when引导的时间状语如果是一般过去时，主句一般用过去进行时。而while也意为“当……时候””，相当于during the time，表示某一段时间历里的情况，故其引导的时间状语从句中的动词必须是延续性的。eg：
While I was watching TV, my mother came back.
=When my mother came back, I was watching TV.
2.while重在强调其后的动作与助于动作的对比，表示“与此同时”。eg：
She was listening to music while I was playing computer games.
3.when/while练习
1）_____ the teacher came in, we were talking and laughing.
2)I got home______ my mother was cooking dinner.

【学习过程】

1.爬树______2.跳下来__________ 3.惊恐的________ 4.火车站________
5.从…出来________6.跑掉______7.寻找______8.某事发生在某人身上________
Step2
情景导入：(1) I was reading the book. The light was off.
(用连词while把两句话连接起来:While I was reading the book, the light was off.)
(2)I was cooking. The door bell rang.
(用while把两句话连接起来:The door bell rang while I was cooking.)
Step3
自主探究：词组用法。
1、be scared to do表示“不敢做某事”，是主观原因。
例如：He is scared to go out at night.
2、be scared of doing 表示“担心出现doing所出现的情况、结果”，doing 是客观上造成的。例如：He is scared of failing in this maths test.
3、小节回顾
1) While 表示“在……过程中”，强调在一段时间内，所以While引导的从句中的谓语动词必须为延续性动词。
如：While was writing a letter ,the children were playing outside.
Mary 写信时孩子们正在外面玩。（此句中主句动词play为延续性动词，强调主句和从句的动作同时发生。）
when连接的状语从句是个特殊句型，前一个分句（谓语动词用过去进行时）+后一个分句（谓语动词用一般过去时）表示在前一个动作正在进行的过程中突然发生了后一个动作
如：I was walking along the road when I met a friend of mine.
