enough to do sth

enough to do。enough后面一般只加不定式，构成固定搭配，意思是足够做某事；足以......；足够……去做某事。  

例句：They need several men strong enough to do the work.

翻译：他们需要几个足够强壮的人来干这个活儿。

用法

adj.（形容词）

1、enough作形容词时，意思是“足够的，充分的”，在句中多作定语，一般修饰复数名词或不可数名词，可置于所修饰的名词之前，也可置于所修饰的名词之后。后者属于旧式用法。

2、当主语是it或是特定数量时，enough也可用作表语，其后常接for引起的短语或动词不定式。

严格来说，两者都可以应用，主要看情景而定。比如：
1. I am old enough to work now. 我已经长大到可以工作的年龄。
2. For me, it is enough doing so much for you！ 在我来说，为你做了那么多已经足够了！
一般而言，enough to do 运用到机会比较多。enough 后面也经常用 of ： I have enough of such harassment！(我受够了这些骚扰了！）

所以得看具体情况来使用。
希望帮到你。

都可以用。
