enough的用法
一、作形容词
Ⅰ、作定语时,既可修饰可数名词,也可修饰不可数名词。
(1)Are there enough seats for ten persons? 有没有足够十人的座位?
(2)We have enough food for a week.我们有足够维持一周的食物。Ⅱ、作表语
只有当主语是代词数词和“数词+名词”时,enough才可作表语用,如果主语是名词,enough便不能作表语用了,如:
(1)That’s enough..Thank you.够了,谢谢。
(2)Five is enough.五个够了。
(3)Will12apples be enough?十二个苹果够不够?
如果enough之后跟其它修饰语(如不定式或for短语时),前面的主语不受限制。如:
(1)The time is enough to finish it.(=There is enough time to finish it) 有足够的时间完成这一工作。
(2)The food is enoug h for us two.(=There is enough food for us two)有足够我们俩吃的食物。
二、作代词,充当主语、宾语.
(1)Enough has been said on this subject 关于这个问题说得已经够多的了。
(2)-Do you need some more materials?你们还需要材料?
-No,thanks.Enough have been supplied for us.不要了,谢谢!我们已经够了。
(3)I have enough to do today. 今天我有足够多的事要做。
三、作副词
修饰形容词和副词,且必须放在它们之后,如:
(1)This room is large enough for us to sleep in.这个房间足够大,我们可以睡.(不可说enough large)
(2)He knows the situation well enough.对他情况了解得非常清楚。(不可说enough well”)
四、当enough和另一形容词同时修饰一个名词时,有两种不同的位置。
Ⅰ、enough放在形容词之后,此时,enough修饰形容词时,结构为“adj.+ enough+名词”,表示“足够…的…”,如:
(1)a large enough room一间足够大的房间
(2)a deep enough well一口足够深的井
(3)I don’t have big enough nails to mend the cupboard.我没有足够大的钉子修理柜子。
Ⅱ、enough放在形容词之前,此时,enough修饰名词,结构为“enough+adj.+名词”,表示“足够多的…”,如:
(1) enough large room足够大的房间
(2) enough deep well足够深的井
(3)I don’t have enough big nails to mend the cupboard.我没有足够大的钉子修理柜子。
五、与介词of构成短语enough of,使用时,须遵守如下规律:
1、enough of+既定词+名词(其中既定词为冠词,物主代词或指示代词)
2、enough of+代词
(1)Is there enough of the blue material?(=Is there enough blue material? 有足够的蓝色料子吗?
(2)I’ve had enough of your complaints.(=I’ve had enough complaints from you) 你的抱怨我已经听够了。
六、enough之后跟介词短语”for sb”和不定式“for sb to do sth”,如:
(1)He was lucky enough to succeed in his first attempt.他够幸运的了,第一次尝试就成功了。
(2)He spoke slowly enough for everyone to understand.他说话慢得每个人都能听懂。
(3)There isn’t enough ice cream for all the children.冰淇淋不够分给所有的小孩。
七、enough不能与no构成否定句,只能借助not以及其他否定词,如:
(1)We have not enough glasses for everyone.(不能说成no enough glasses.我们的杯子不够分给每个人。
(2)We had hardly enough food to go around at the picnic.(不能说成no enough food.我们的食物刚够分给参加野餐的人。
