Designer:Ji Ping
Section A 第一课时
一、Knowledge aims：
1、 A:What were you doing when the UFO arrived ?
B:I was standing in front of the library when the UFO arrived.
2、 A:What was the boy doing when the UFO landed?
B:He was sleeping late.
二、Important point：过去进行时 was / were + doing sth.
三、Difficult points：过去进行时时态的熟练运用，when 和while 的用法区别
四、Teaching and learning course：6课时
五、预案
Step1 自主学习
1.一个飞碟____________ 2.在理发店_________ 3.在盥洗室_________
4.在卧室__________ 5. 在厨房里____________ 6.出去_______________
7.一个外星人__________ 8.报警__________ 9.航天博物馆____________
10. 起飞________ 11.kid(现在分词)_________ 12.一次不寻常的经历_______________
Step2 语法认知
（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。
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
把上句改写为否定句： _____________________
(3)一般疑问句式：Was/Were +主语+v-ing？
把上句改写为一般疑问句，并做出肯定和否定回答：_____________________
肯定回答：Yes，______________ 否定回答：No，______________
(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前边动作同时进行，表示“与此同时”。eg：她一边玩电脑一边听音乐。
She was listening to music she was playing computer games.
用when与while填空
1）_____ the teacher came in, we were talking and laughing.
1
2
2)I got home______ my mother was cooking dinner.

6)太不可思议了。__________________________________
2.再读短文，回答问题。
1）When did the UFO land ? what was the writer doing ?

10.某事发生在某人身上______________ 11.从…到…的航班______________12.北京国际机场
五、学案
1、小节回顾
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.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: __________________________________________
(2)I was cooking. The door bell rang.
. 用when把两句话连接起来: __________________________________________
3.探究与拓展：
1）be scared to do表示“不敢做某事”，是主观原因。相当于be afraid to do
例如：他不敢在夜晚出去He is scared to___________________________________
5
6
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：他担心在这次数学考试中失败。He is scared of ___________________________________
2) 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。例如：He_________my name , when he got to the top of the mountain.
（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 _________me if I do something wrong
(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 _________him because he was far away.
