We can use the verb to be + adjective + enough + to-infinitive to describe a person’s personality and abilities.
Attention!
enough是副词,修饰前面的形容词。
enough位置在被修饰词的后面。
He is old enough to go to school.
Andy is strong enough to be a player.
Examples:
the adjectives that can be used to describe a person’s personality and abilities, e.g.:
good kind nice
clever careful rude
wise careless silly
honest polite brave
以上我们已经通过归纳总结和练习对本课的语法内容有了一定的了解,下面就让我们根据之前练习的考察情况进一步选择讲解该语法项的重难点。
Ⅰ. enough作定语,意为“足够的,充分的”, 位于名词之前。
I have enough money for the book.
我有足够的钱买这本书。
You have enough time to do it.
你有足够的时间来做这件事。
Ⅱ. enough作状语,意为“充足地,充分地”,修饰形容词或副词,放在形容词或副词之后。
That coat is dear enough.
那件大衣很贵。
Is this good enough
这个够好吗?
Ⅲ. enough作表语,意为“足够的”。
Six bottles should be enough.
六瓶应该够了。
enough的用法
“be + adj. + enough to do sth.”意为“足够……来做某事”。
☆当该结构的主语是指人时,用来描述该人的性格特征及能力 。
e.g. Betty is generous enough to buy souvenirs for all her classmates.
贝蒂很慷慨,给所有的同学买了纪念品。
Amy is old enough to wash her own clothes.
艾米够大了,可以自己洗衣服了。
enough to的用法
☆当该结构的主语是指事物时,用来描述某事物的特征,此时,enough后通常加“for sb.”。
e.g. The car is cheap enough for Tom to buy.
这辆车足够便宜,汤姆买得起。
Pay attention
1. enough是副词,修饰前面的形容词。enough用作副词时,位置在被修饰词的后面。
He is old enough to go to school.
Andy is strong enough to be a player.
Pay attention
2. 在使用本句型的时候,要注意主语和be动词的一致性。形容词前没有任何诸如very,quite等之类的修饰词。
The room is big enough to hold 20 people.
Example:
He is outgoing enough to make friends easily.
= He is so outgoing that he can make friends easily.
他很外向,很容易交朋友。
“be + adj. + enough to do sth.”句型可以和so …that …互换。

可以用“to be + too + adjective + to do”的结构来表达一个否定的结果,意为太......不能,不会。如:

他太累了,不能继续工作。

注意:
too…to结构和never一起使用是并不表示否定。
如:

活到老,学到老。
可以在不定式前加介词for引出逻辑主语。如:
1.The box is very heavy. The little boy cannot to carry.
= The box is too heavy for the little boy to carry.
这个箱子很重。这个小男孩搬不动。
2.The apple is very high. The child cannot reach it.

Attention!
Examples:
● He is not old enough to do the work.
=He is too young to do the work.
● The problem is too difficult for me to work out.
=The problem isn’t easy enough for me to work out.
enough to的句式为否定式时,enough to可以转换为too … to结构。但转换后的too … to结构中的形容词要用其相应的反义词。
1. He is too young to work.
= He is not old enough to work.
2. The girl is too short to see it.
= The girl is not tall enough to see it.
3. The question is too hard for me to answer.
