英语·八年级·下册（沪教版） 课时3语法 课时笔 A.It is adj.+for n./pron.+to +v. 句型“Itis+ad.+for sb.to do sth.”表示“对某人来说，做某事是…的”。其中的形容词是对所做 的事情进行描述，如difficult,easy,hard,important,necessary,dangerous,possible,convenient等。 如： It's very dangerous for children to cross the busy road by themselves. 对孩子们来说，独自穿过繁忙的马路很危险。 It's difficult for us to finish the work.对我们来说，完成这项工作很困难。 此类句型中，主语是一个不定式短语。为了避免因主语过长造成“头重脚轻”，所以常用t作形式 主语，而将真正的主语（不定式短语）放到后面。因此以上两句相当于： To cross the busy street by themselves is very dangerous for children. To finish the work is difficult for us. B.adj.enough to do sth. 句型“sb./sth.+be+ad.+enough to do sth.”意思是“某人或某物足够…，可以做某事”。注意 enough放在形容词后面，表示达到必要的程度。如： He is strong enough to lift the big stone.他强壮得足以举起这块大石头。 The room is not big enough to hold20 people.这个房间不够大，容纳不了20人。 拓展：此句型的否定形式可与to0…to.…(太…而不能…)，$s0…hat.（太…以至于…)句 型互相转换。如： The room is too small to hold20 people.这个房间太小了，不能容纳20人。 The room is so small that it cannot hold20 people..这个房间太小了，容纳不了20人。 C.It is adj.of n./pron.to do sth. 句型“Itis+ad.+ofsb.to do sth.”的意思是“某人做某事真是太…了”。其中的形容词是对人 的性格、品质进行描述，如kind,good,nice,clever,careless,,polite,foolish等。如： It's very kind of you to help me.你来帮我真是太好了。 It was clever of him to work out the maths problem.他真聪明，解出了这道数学题。 这个句型可以转换成：sb.+be+ad.+to do sth.如： You're kind to help me.
