重点语法：enough...to...和too...to...的用法精讲练
语法知识精讲
enough...to... 和 too...to... 的用法
这两个结构都用于表达“程度与结果”的关系，但含义和用法截然不同。
1. enough...to...（足够……以至于……）
表示“达到某种程度，能够做某事”，是肯定意义。
结构：
- 形容词/副词 + enough + to do sth
- enough + 名词 + to do sth
例句：
- He is old enough to drive. （他年龄足够大，可以开车了。）
- She runs fast enough to win the race. （她跑得足够快，能赢得比赛。）
- We have enough time to finish the project. （我们有足够的时间完成这个项目。）
否定形式：not enough...to...（不够……以至于不能……）
- The boy is not tall enough to reach the shelf. （这个男孩不够高，够不到架子。）
2. too...to...（太……以至于不能……）
表示“超出某种程度，导致无法做某事”，是否定意义。
结构：
- too + 形容词/副词 + to do sth
例句：
- He is too young to drive. （他太小了，不能开车。）
- The box is too heavy to carry. （这个箱子太重了，搬不动。）
- She was too tired to continue working. （她太累了，无法继续工作。）
特殊情况：
- 如果句子主语和不定式（to do）的主语不同，可以加 for sb：
- The coffee is too hot for me to drink. （咖啡太烫了，我没法喝。）
3. 对比 enough...to... 和 too...to...
| 结构 | 含义 | 例句 |
| enough...to... | 足够……可以…… | She is strong enough to lift the box. |
| too...to... | 太……以至于不能…… | She is too weak to lift the box. |
4. 常见考点
1. enough 的位置：
- 形容词/副词后（old enough）
- 名词前（enough money）
2. too...to... 本身就含否定，不能再加 not：
- He is too not old to drive. （错误）
- He is too young to drive. （正确）
3. so...that... 替换：
- He is too tired to walk.
= He is so tired that he can’t walk.

1．He was too _______ to cut himself with the knife.
A．careful B．carefully C．careless D．care
【答案】C
【详解】句意：他太粗心了，以至于用刀割伤自己了。A.careful小心的，形容词；B.carefully仔细地，副词；C.careless不小心的，不仔细的， 粗心的，形容词；D.care照料，照顾，动词。根据too后面跟形容词或副词，该句的动词是be动词，此处用形容词而不接副词。故排除B和D；根据句意可知，此空是不小心的，不仔细的， 粗心的意思，故排除A，故选C。
