enough

1.注意下面各句里enough前面的名词前都没有a：

• He was fool enough to believe what the cheat said.
• He was gentleman enough to help her.
• He was scholar enough to read the inscription.
• He was not blunderer enough to repeat his mistake.

2.enough用在它所修饰的名词的前面或后面都可以，如We have enough manpower和We have manpower enough。但enough在用作副词的时候几乎总用在它所修饰的词的后面，如He is clever enough和He writes well enough。She is a good-tempered enough girl和She is a good-tempered girl enough两句里的enough的作用不同：在第一句里enough修饰good-tempered，在第二句里enough修饰good-tempered girl。

3.比较下面两句：

• I am glad to see you.
• We are strong enough to be able to resist aggression.

第一句里没有enough，第二句里有enough，就语法讲，to see修饰形容词glad, to be able to resist aggression修饰副词enough。第二句里的enough不可省去。

初学者往往在该在形容词和不定式的中间用enough的场合不用enough。哪里该用enough，哪里不该用enough，有下面的一条规则：可以用so...as to...（不定式）的场合该用enough，不可用so...as to...（不定式）的场合不该用enough。如We are so strong as to be able to resist aggression是可以说的，所以该用enough。I am so glad as to see you是不可说的，所以不该用enough。注意不可说...enough as to...（不定式），如不可说We are strong enough as to be able to resist aggression。

对于这条规则，也许要发生些疑问，因为有时好像用enough或不用enough都通。是的，下面每组里的两句都通：

• He is ready to accept the offer.
  He is ready enough to accept the offer.
• He is lucky(或fortunate)to have such a son.
  He is lucky(或fortunate)enough to have such a son.

但注意：第一组第二句里的to accept并不修饰enough，却是修饰ready, ready enough作very ready解，enough跟to accept并没有关系。第二组第一句是“他有这样的一个儿子是幸运的”。第二组第二句是“他幸而有这样的一个儿子”。两句的意思不同。注意下面每组里的两句意思不同。

• You were kind tocome.(你的到来证明你的好意。)
  You were kind enough to come.(你好意而来。)
• He is careful to pronounce the words correctly.(他很仔细地读对了这些单词。)
  He is careful enough to pronounce the words correctly.(他很仔细,所以这些词都读对了。)

下面各形容词通常在其和后面的不定式的中间用enough：

bad, brave, careless, clever, courageous, cruel, dangerous, foolish, good, high, honest, imprudent, large, long, low, old, old-fashioned, patient, poor, prudent, rich, sensible, shrewd, silly, strong, tall, weak, well, wide, wise, young

4.下面每组里的两句意思相同：

• He is a decent enough clerk.
  He is a decent clerk enough.
• She is a good-tempered enough girl.
  She is a good-tempered girl enough.

5.I cannot see enough of you是“我跟你见面愈多愈好”。参见can 7
