enough 的位置
enough 修饰形容词、副词时放在它们后面，修饰名词时放在前面。
adj / adv + enough ／ enough + 名词 ／ … enough to do
要点
- 修饰形容词、副词要后置：old enough，quickly enough，good enough。
- 修饰名词要前置：enough water，enough time，enough money。
- 「足够……做某事」= adj / adv + enough + to do：He is strong enough to carry the box.
- 否定式 not ... enough to do 表「不足以」：She is not tall enough to reach the shelf.
- enough 也能单独作代词：Have you got enough?
- enough 修饰名词时占的是限定词的位置，前面不能再加 a / the / my：enough time（不说 an enough time）。
- 句子的"做某事的人"与主语不同时，to do 前要挂 for：The box is light enough for me to carry.
- enough 后可跟 of + 名词，也能单独作代词：enough of the talk（别再说了）／ Have you got enough?
例句

我们的钱不够买那辆自行车。

他讲得不够响，我们听不清。
Is the food enough for ten people?
这些食物够十个人吃吗？
Is the box light enough for you to carry?
这箱子够轻，你搬得动吗？
We have enough time to finish the work today.
今天我们有时间把这活干完。
易错提示
- 中文说「足够好」，英文必须 good enough，写 enough good 就错了。
- to ... too ... to 与 adj + enough to 意思相反，可互相改写：He is too young to do it = He is not old enough to do it.
- 记「名前形后」四个字：修饰名词放前面，修饰形容词副词放后面 —— enough water 但 big enough。
- 别在 enough 与 to do 中间塞宾语或 for doing：enough money to buy the bike（不写 enough money for buying the bike）。
