沪教版八年级下册 Unit 5-8 重点语法归纳

八年级下册 Unit 5-8 重点语法归纳 Unit 5 Good manners 语法主题：enough to 和 too...to 的用法 考点1 enough to 的用法 含义：表示“足够……做某事”。 结构： 形容词/副词 + enough + to do sth. （注意：形容词或副词要放在 enough 之前） enough + 名词 + to do sth. （注意：名词放在 enough 之后） He is strong enough to carry the heavy box. (他足够强壮，能搬动这个重箱子。) I have enough money to buy a gift. (我有足够的钱买礼物。) 考点2 too...to... 的用法 含义：表示“太……而不能……”，具有否定含义。 结构： too + 形容词/副词 + to do sth. The boy is too young to go to school. (这个男孩太小了，不能去上学。) 【规划变化】句型转换 1. too...to... 与 not...enough to... 互换 The question is too hard for me to answer. = The question is not easy enough for me to answer. 2. too...to... 与 so...that... (否定句) 互换 He is too tired to walk. = He is so tired that he can't walk. 【易错点】 在 too...to... 结构中，如果主语是物，且不定式的宾语就是句子的主语，那么不定式后不再加宾语（代词）。 误：The water is too hot to drink it. 正：The water is too hot to drink.
