Unit5 Good Manners重点语法：too...to...和enough...to...（精讲精练50题） ★语法讲解★ too…to太….的用法 1. “too+形容词或副词+to+动词原形”，通常翻译成“太…而不能…” The ice is too thin to bear your weight. The firm is too small to compete against large companies. 2.for sb引出不定式的逻辑主语 根据语境的需要，不定式前可以带有一个由介词for引出的逻辑主语。 The road was too narrow for cars to pass. He spoke rather too quickly for me to understand. enough to的用法 用作形容词.意思是“足够的,充分的”,修饰名词时放在名词前面,也可以放在被修饰的名词后面常用句式为：enough＋名词＋for sb./ sth.或者 enough＋名词＋（for sb.）to do. There is enough food for all the people. I have enough time to collect the stamps. 有些形容词不能被 enough 修饰,如 glad, pleased等;可以被enough 修饰的形容词有old, poor, rich， clever, strong, high, tall, wide, wise 等 如：他看见你很开心。 正:He is very glad to see you. 误:He is glad enough to see you. “形容词/副词＋not enough (for sb.) to do sth. 可以与“too＋形容词/副词＋(for sb.）to do sth.”相互转换,只是这两个句子中的形容词要互为反义词,前一句型要用否定句,它也可以与“so...that...”句型相互转换。 例如：箱子太重他搬不动。 The box is too heavy for him to carry. =The box is not light enough for him to carry. =The box is so heavy that he can't carry it. The money is enough for me to buy a gift for my mum. ★真题试炼★ 一、单项选择（每小题2分，满分100分） 1．---Are you _______ to do your favorite things? ---Yes. I have enough time _______ them.
