Why dont you go to sleep earlier this evening? 今天晚上你为什么不早点睡觉呢？(P25 1c) Why dont you ? 句型的用法Why dont you do sth 相当于Why not do sth? 意为“（你）为什么不做某事呢？”表示建议对方做某事。肯定回答：OK! / All right./ Great idea. / Yes, I think so .否定回答： Sorry, I / Im afraid not.例如： Why dont you go shopping / take a vacation ? = Why not go shopping / take a vacation ?

Im not good at writing letters. 我不擅长写信。 （P26 2b）be good at 的用法。be good at意思为“擅长”，后面接名词或动名词做宾语。例如： Helen is good at English / playing basketball. Helen 擅长英语/ 打篮球。辨析 ： be good to , be good with , be good for. (1) be good to意为“对友好”My friends are good to me when I was ill. (2) be good with 意为“与相处的好” He is very good with the children. (3) be good for 意为“对有好处/有益”Eating more vegetables is good for your health.练习： （1）English id my favorite subject, and Im good _ it. A. for B. to C. at D. of (2)我擅长下象棋。I _ _ playing chess. (3) 水果对我们的健康有好处。 Fruit_ our health.3. Well, you should call him so that you can say youre sorry. 哦，你应该给他打电话，这样你就可以对他说对不起。 （P26 2c）本句中so that 引导的“you can say youre sorry”是目的状语从句。so that 的用法so that 意为“以便，以至于”，引导目的状语从句，此时可与in order that 换用；从句中常含有情态动词 may, can/could, should, would 等I spend more time learning English every day so that(= in order that) I can make greater progress this year.今年为了取得更大的进步，我每天花费更多的时间学英语。（扩展）so that 意为“因此，所以”时，还可引导结果状语从句，此时不能与in order that 换用，主从句之间可以用逗号隔开。She didnt planned her time well, so that she didnt finish her homework on time.她没有把时间计划好，所以没能按时完成家庭作业。练习：The teacher asked me to read aloud _ all the students could hear me. A. in order to B. for C. because D. so that 4.
