过去进行时
1.意义：表示在过去某一时刻或某段时间内正在进行的动作

3.例句：
He was cooking in the kitchen at 12 o’clock yesterday .昨天12点，他正在厨房烧饭。
She was writing a letter when I came in .我进来时，她正在写封信。
What were you doing all day yesterday 昨天一整天你都在做什么？
Step4:以奥运会的开幕导入,学生结合实际来回答问题。
--- What were you doing when the Olimpic Games began ---I was Ving … .
Step5: 奥运会让我们兴奋，而有一样东西一直以来让我们感到神秘，请同学们看图片：
UFO: Unidentified Flying Object 不明飞行物
One day, a UFO visited a small city. What happened Let’s have a look.
Look at the people in the city, where were they when the UFO arrived
Read the sentences in 1a and finish it.
区分in front of & in the front of
Finish 1b, listen and circle the correct responses.
Step6:Role play:结合1a, 1b完成对话。
A: Where were you when the UFO arrived
B: I was… .
A: Were you …
B: Yes, I was. / No, I wasn’t.
Step7:2a listening
先自读句子，熟悉句意，老师点明需要注意的词或短语：bought a souvenir, land on Center Street, got out of… .
Listen and number the statements in the order you hear them.
Step8:2b Creful plete the following sentences with “when” or “while”.
The boy was walking down the street ______a UFO landed.
The girl was shopping ______ she saw the alien get out.
______ the alien was buying a souvenir, the girl called the police.
______ the alien was visitng the museum, the boy called the TV station.
Check the answers: when when while while
学生找规律：可能会发现when 后面都是一般过去时，而while 后面都是过去进行时。
告诉学生准确的区别：when 后常用非延续性动词，而while后必须是表示动作或状态的延续性动词 。所以我们见到的while后从句都是表状态的主系表结构或表动作的进行时态，when后常是一般过去时。
根据以上区别要求学生改写句子：
______the boy was walking down the street, a UFO landed.
______the girl was shopping, she saw the alien get out.
The alien was buying a souvenir _____the girl called the police.
The alien was visiting the museum ______the boy called the TV station.

When the UFO arrived, S1 was sleeping.
