too to 的用法

A.too...to...结构意为“太 而不能 ”,形式上是肯定式但表示否定之意,故不定式“to+v.(原形)”不能再用否定词not。例如:

1.你年龄太小而不能上学。

【误】You're too young not to go to school.

【正】You're too young to go to school.

B.too...to...结构中的too是副词,其后修饰的是一个形容词或副词,不可换用 very,so,quite,rather等表程度的副词。例如:

2.昨天他们来得太晚没能赶上早班火车。

【误】They came very(so,quite,rather)late to catch the early train yester- day.

【正】They came too late to catch the early train yester- day.

C.too...to...结构是个简单句,可转换为so...that...复合句,但两者不可混用。例如:

3.我刚才累得走不动了。

【误】I was so tired to walk on just now.

【正】I was so tired that I couldn't walk on just now.

【正】I was too tired to walk on just now.

D.too...to...结构的主语在逻辑上为后面不定式的宾语时,不定式必须省略相应的人称代词。例如:

4.这盒子太重了我搬不动。

【误】This box is too heavy for me to carryit.

【正】This box is too heavy for me to carry.

E.too...to...结构也可转换为not...enough to...形式,此时的不定式表示的却是肯定之意。例如:

5.这冰太薄不能在上面滑。

【正】The ice is too thin to skate on.

【正】The ice isn't thick enough to skate on.
