Unit 5 Good manners Grammar 知识点： 1. enough to的用法 我们可以用“be动词+adj. +enough+to +do”来描述某人的品质和能力，意为“…足够…做某事”，可以与“so+adj.+that…”句型转换。 （注意：实义动词+ adv.（副词） + enough + to do sth.） enough可以作状语、定语和表语。 The house is not big enough for us. (状语) Have you got enough money (定语) Six bottles should be enough. (表语) 2. too…to的用法 （1）我们可以用“be动词+too+adj.+to do”来表达一个否定的结果，意为“太...而不能...”。 （2）too…to…结构可与so …that…not…句型进行转换 （3）too…to…结构也可转换为enough to结构，通常enough to结构中使用的形容词是too…to…结构中使用的形容词的反义词,“too + adj. + to do = be + not + adj. + enough + to do”。 （4）too…to…结构中我们可以在动词不定式前加介词for引出逻辑主语。 （注意：实义动词+ too + adv.（副词）(for sb.) + to do sth.） 同步练习 一、根据句意及中文提示、英文解释或通过上下文，写出句子所缺单词 1.
