'); })(); 在英语中,Enough一词使用频率之高是人人皆知的,它的基本意思是“充分的,足够的,充分的”,它既可作形容词、副词用,也可作代词用。下面小编就来详细介绍下 enough的用法说明,希望对大家有用。?  enough的用法说明如下:?  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) Will 12 apples 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 enough 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。
