(时间:60分钟,满分:100分)
Grammar1---be+adj.+enough+ to-infinitive的用法。
★★★在enough to---短语中,enough 是副词,修饰形容词、副词或动词,位于所修饰词之后,意思是“十分地;充分地;足够地;充足地”,与不定式to连用,在句子中作状语,表示程度。如:
Is the room large enough to have a meeting? (修饰形容词)
Amy runs quickly enough to catch the bus.(修饰副词)
He knows the situation well enough.他对形势了如指掌。(修饰动词)
▲▲▲我们在使用enough时,还需要注意以下几点:
1.enough不能与no连用。如:
I have no enough money to buy a car.(X)
I don't have enough money to buy a car.(√)
2.enough用作形容词时不可被very修饰,但可以用quite修饰。例如:
We have quite enough time.我们有足够的时间。
3. 用在“主语+cannot/can never…+enough”句型中,“主语+can't/can never…+enough”句型形式上是否定句型,实际上表达的是肯定意义,表示“越……越……;无论怎样……也不过分”。例如:
You can never be careful enough. 你越细心越好。
We can't thank him enough.我们无论怎样感谢他也不过分。(我们怎么感谢他都不算过分。)
Grammar 2------be+too+adj.+ to-infinitive的用法。
We can use “ to be + too +adjective + to-infinitive” to express a negative result.意为:“太……而不能做某事”;“太 …… 以至于不能……”。即我们可以用“be + too + 形容词 + to do sth”结构来表达一个否定结构,意思是“太……而不能做某事”;“太 …… 以至于不能……”。如:
He is too tired to go on working.他太累了,不能继续工作。
He was too slow to write down all the main points. 他太慢了,没能记下所有的要点。
以上两种结构有时可以转换,注意其中的形容词要作相应的变化,即:enough前的形容词与too之后的形容词互为反义词,同时应改为not…enough to的形式。
He is too young to look after himself. 他年龄太小不能照顾自己。
= He is not old enough to look after himself.
拓展:
***so+adj/adv+that +句子(肯定句): “如此------以至于------能做某事”。
so+adj/adv+that+句子(否定句): “如此------以至于------不能做某事”。
such+adj+名词+that+句子(肯定句): “如此------以至于------能做某事”。
such+adj+名词+that+句子(否定句): “如此------以至于------不能做某事”。
such+ a/an +adj+单数名词= so +adj+a/an+单数名词。
She is so heavy that she can’t run fast.
=She is too heavy to run fast.
=She is not light enough to run fast.
=She is such a heavy girl that she can’t run fast.
=She is so heavy a girl that she can’t run fast.
