enough to句型的用法

Answer 1

enough to句型的用法

该结构的基本形式为“形容词或副词+enough to+动词原形”，其意为“足够地…可以…”：

He is old enough to take care of himself. 他大了，能照顾自己了。

Will you be kind enough to shut the door? 可否劳驾把门关上?

She is old enough to travel by herself. 她年纪够大，可以独自旅行了。

Is the river deep enough to swim in? 在这条河里游泳水够深吗?

【注】若enough前出现否定词，则不仅否定了enough，而且也否定其后的不定式：

He was not strong enough to do the work. 他不够强壮，不能做这工作。

He is not strong enough to lift the box. 他力气不够大提不起这个箱子。

另外，该句型有时可与so [such]…that结构转换：

He is rich enough to buy a plane. 他很有钱，可以买一架飞机。

→He is so rich that he can buy a plane. 他很有钱，可以买一架飞机。

有时该句型也可与too…to句型转换：

He is too young to go to school. 他太小，还不能上学。

→He is not old enough to go to school. 他还不够大，还不能上学。
