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.
3)They were dancing _____ we came to meet them.

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.)
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.
2) She&s shouting.
A shout,shout at,shout to 的用法
（1）shout 的意思是&大叫、呼喊&，指为了使人听见或引起注意而提高声音。
（2）shout at sb. 对某人大声喊叫，表示某人非常生气，冲着另一个人大喊大叫，态度不好。例如：
He&ll shout at me if I do something wrong ,so I should be careful enough not to annoy him.
(3)shout to sb.由于相隔距离远，声音小了听不见，因而高声喊叫某人。例&Come and help me ,please&she shouted to him because he was far away.
