1. not…at all 用于否定句,意为“根本不、 一

点也不”。如: It wasn’t difficult at all. 这一点也不难。 There was nothing to eat at all. 根本没什么可吃的。 To try and fail is better than not to try at all. 尝试而失败也比不尝试好。

注:在否定句中,at all 可位于句末, 也可跟在否定词后。如: He isn’t tired at all. / He’s not at all tired. 他一点也不累。

另外,在口语中单独说 not at all, 可用来回 答感谢或道歉。如: A:Thank you very much. 多谢你了。 B:Not at all. 不客气。 A:I’m sorry to keep you waiting. 对不起,让你久等了。 B:Oh, not at all. 噢,没关系。

1. 我一点也没生气。 I am not angry at all. 2. 他们一点也不喜欢牛奶。 They don’t like milk at all. 3. 休一点也不喜欢语文。

2. at least 至少 例如: We should brush our teeth at least twice a day. 我们每天应该至少刷两次牙。 A good cigarette will smoke at least ten minutes. 一支好烟至少可以抽10分钟。 反义短语:at most 至多

3. although 虽然;尽管 例如: Although my uncle is old, he looks very strong and healthy. 我的叔叔虽然老了,但他看上去还是很 健壮。 注意: although引导的从句不能与but, however连用,但可与yet, still连用。

_______ he is ill, _______ he goes to school. A. Although, but B. /, / C. Although, / D. But, although C although 表示“仍然”,不能和but同时 使用。 I’m not very strong, ____ I usually exercise . A. because B. and C. although C 前后意义有转折。

4. It is + adj. to do sth. 干某事是?? 例如: It is interesting to play computer games. 玩电脑很有趣。 -It is very important _____ C make a plan before a new term. -Yes. You must try to make it carefully. A. of B. for C. to

5. spend v. 花费;消耗 例如: How did you spend your summer vacation? 你是如何度过暑假的? I spent 5 yuan on this book. 这本书花了我五十元。

辨析 take, spend, pay
例如: It usually takes me half an hour to do my homework. 做作业通常花费我半小时的时间。 Students often spend one and a half hours (in) doing homework. 学生们经常花一个半小时的时间做作业。 I paid 10 yuan for this book. 我买这本书付了十元钱。

根据以上例句可知: It takes sb. some time to do sth. 意为“花 费某人??时间来做某事”。 spend 的主语必须是人,而spend …on sth. 意为“买某物花了??钱”。spend +时间 +(in) doing意为“花费多少时间来做某事”。 可以与it takes sb. some time to do sth. 来进行 句型转换。 pay 的主语必须是人,而“花钱买某物” 为pay … for。

It usually takes me a few minutes to make my bed. (改为同义句) spend a few minutes I usually ________ making my bed. _________
