一、句型 enough to do sth.表示“足够...以至于做某事”,不定式是结果状语.
二、enough 既有形容词属性也有副词属性,在意思上没有区别,都表示“充足/ 足够”这个概念.在具体时使用要注意以下两点:
1、作为形容词是用来修饰名词的,既可以放在名词前也可以放在名词后,如:
* 有足够的食物供大家吃.
--There is enough food for everybody.
-- There is food enough for everybody
* 我们有足够的钱花.
-- We have enough money to spend.
-- We have money enough to spend.
2、作为副词可以修饰形容词或副词,但是只能放在被修饰词后,如:
* He was fool enough to agree.他同意了,真够傻的(他足够傻以至于同意了).(修饰形容词 fool)
* We were glad enough to leave.我们很高兴离开(我们足够高兴以至于要离开).(修饰形容词 glad)
* Be good [kind] enough to reply early.请早日赐复/劳驾尽早回复(请足够慈善以至于早日回复)
* He didn't run fast enough to catch the train.他跑得不够快,没赶上火车(他跑得不够快以至于 没赶上火车).(修饰副词 fast)
