We use them to talk about two or more actions that happen at the same time.Step 3：Ask four students to read out the examples on page 71 and spend more time to explain them. Ask some able ones to give their own sentences .Step 4：Explain the context of the exercise at the top of page 72. Millie is asking Daniel about what he did last night. Ask students to read through the conversation and complete with while and as.【要点点击】1. while / as的用法(1). while用作连词，意为“在期间”“当时候”。它表示某个动作正在进行时另一个动作发生了；还可以表示某个动作还在进行的同时，另一个动作也在进行之中。它只表示时间段，所以while引导的从句的动词必须用持续性动词或状态动词。其时态一般限于进行时或状态动词的一般时。如：我父亲在看报时睡着了。My father _ asleep_ he was _ the newspaper. 我在做练习时，同桌在读书。_ I am doing the exercises, my deskmate _ _.while还可以表示“然而”，用作两个人或物的比较。如：我喜欢音乐而我的哥哥喜欢体育。I like music _ my brother _ sports. (2).as作连词，引导时间状语从句，意为“当时候”，强调at the same time，不指先后，而指同时发生，尤指短动作或事件同时发生。当你离开时，请随身带件雨衣。_ you leave, please take a raincoat with you. 当我下车时，有人走上前来。_ I got off the bus, someone came near.as作连词，可引导原因状语从句，意为“因为”，语气较because弱。因为他有一些练习要做，他没和我们一起去。_ he had some exercises to do, he didnt go with us. as作连词，可引导方式状语从句，意为“按照”“如同”。如：You must do everything as I do.你必须如同我做的一样来做每一件事。When at Rome, do as Romans do. 入乡随俗。（在罗马时就要像罗马人那样做）Please do as I told you. 请按照我告诉你的去做。注意：while和as引导的时间状语从句在时态上必须和主句保持一致。2. 副词比较级和最高级的变化形式与形容词的相同，有规则和不规则两种。构成法原级比较级最高级直接加r/-stlatelaterlatest加er/-esthardharderhardest去y为ier/-iestearlyearlierearliest加more/ mostcarefullyslowlymore carefullymore slowlymost carefullymost slowly3. 不规则变化原级比较级最高级wellbetterbestbadlyworseworstmuchmoremostlittlelessleastfarfarther/furtherfarthest/furthest4. as副词原级as，“与一样”，表示同级比较，否定句中可用soas ：Sandy 和Millie跑得一样快。 Sandy runs _ _ _ Millie.他在测试中做得没有我好。He didnt do as/so _ as I in the test.5. 副词比较级than，“比更”他们现在生活得比以前幸福。They live _ _now _ before.6. 副词比较级and副词比较级，“越来越”你学习越来越努力了。You study _ _ _.雨下得越来越大。It is raining _ _ _ _._ _ _.7. the+副词比较级，the副词比较级，“越就越”我越看到他，越不喜欢他。The more I see him, the less I like him.8.（the）+副词最高级比较范围（三者或三者以上）“最”Jack是所有学生中跳得最高和最远的。Jack jumps （the）_ and _ of all the students.【达标检测】( ) 1.This road is _ road in Tai Cang.A. the two widest B.a second widest C.the second wider D. the second widest( )2.Lucy fell asleep_ she was listening to music.A. before B. while C. after D. as soon as ( )3.I am not feeling _ today.

Herbert answers, Im coming! and goes right back to sleep. Im not at all like my brother. I dont like to go to bed at night but I dont mind getting up in the morning. I usually wake up before my mother calls me. I jump out of bed and go into the bathroom to take a shower. I get dressed, brush my teeth, comb my hair, and get ready to go downstairs for breakfast as soon as my mother calls.But not Herbert. He just sleeps. A military band (军乐队) in our bedroom could not wake him up. I call him and say, Get up! Mum will be up here to pull you out of bed if you dont get up immediately! But he just sleeps. After calling a few more times my mother has to come upstairs and pull Herbert out of bed. Its that way every day with my little brother. Perhaps some day hell learn to get up on time, but I really dont think so.（ ）1. The most terrible thing in life for my little brother is going to school.（ ）2.
