Step6.Listening Listen to a piece of news that an UFO landed in the neighborhood, and let the students fill the blanks with “when” and “while”. Step 7.Grammar Focus 2: the differences between when and while Go over the sentences in the listening task and try to find out how to use“when, while”. First let students say out their opinions completely, and then the teacher sums up the rules. (一)when 和 while 都有“当时候”的意思。when 既可示某一时间点,也可以表示某一 段时间。在 when 引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的， 可与主句中的谓语动词同时发生,也可在其后发生。 例如:1. I was just reading a book when she came into my room.她走进我房间时,我正在看书。 2. Were you writing when the teacher came in? 老师进来的时候,你在写信吗? 3. When he was a child ,he was always fishing with his father.他小时候就常常和他父亲一 起钓鱼。 (二) while 只能表示某一段时间,不能表示某一时间点。在 while 引导的时间状语从句中,其谓 语动词只能是延续性的,而且也只能与主句中的谓语动词同时发生或存在。 例如:1. While Jim was mending his bike, Lin Tao came to see him.正当吉姆修自行车时,林涛 来看他。 2. You cant do your homework while youre watching TV.你不能一边看电视一边做家 庭作业。 (三)另外,when 和 while 的区别还在于: while 引|导的时间状语从句多用于进行时态,而 when 引导的时间状语从句多用一般时态。 例如:1. While they were talking, the bell rang 正在他们谈话的时候,上课铃响了。 2. I was doing my homework when my mother came back home yesterday evening.昨天 晚上妈妈回家的时候,我正在做家庭作业。 Step8. Practice Do some exercise to consolidate the usage of when and while. Step 10 Groupwork Suppose: An UFO landed in the neighborhood last night .Make a interview in group to learn about what they were doing when the UFO landed. And then write a report to CCTV.
