need用法解析
need一词是中学英语“四会”(听、说、读、写)词汇之一,能够充分理解和正确运用它是教学大纲的必然要求.但由于其词性多变,许多学生对它满怀疑惑,特别是在需要将句子变为否定与疑问的时候不知是在其后加not呢,还是借助助动词.
虽然need一词的汉语意思都与“需要”有关,但就词性而言,它可用作实义动词、情态动词和名词;词性发生了变化,它的用法与在句子中所起的作用也随之改变.
一.用作实义动词
作为实义动词,need后面的宾语可以是名词、动名词、动词不定式或代词,这种情况下,need既可用于肯定句,也可用于否定句和疑问句,构成否定句和疑问句时要借助于助动词do或does.
1.need sth.
这是need最常见的用法之一,其后的宾语可以是名词,也可以是代词.如:
1).We need a great deal of money now.我们需要和多钱.
2).They don’t it any more.他们不再需要它了.
3).Does your father need any help?你爸爸需要帮助吗?
2.need doing 与 need to be done
need后面可跟动名词作宾语,这种情况下应注意两点:
①.主动形式的动名词doing具有被动的含义;
②.该动名词可以改为其动词不定式的被动形式而句子的意义不变.例如:
4).The door needs painting.
= The door needs to be painted.那扇门需要油漆一下.
5).Your car needs mending.
= Your car needs to be repaired.你的车需要维修了.
3.need to do sth.
作为实义动词,need后面需要接带to的动词不定式,表示有义务或责任去做某事.如:
6).What do we need to take for the picnic?野餐我们需要带些什么?
7).Will we need to show our passports?我们需要出示护照吗?
8).You need to take good care of your mother.你要好好照料你妈妈.
二.用作情态动词
作为情态动词的need具有情态动词的一般性质,要充分阐释作为情态动词的need的用法,务必首先说明白情态动词的特征.情态动词的主要特征:
①.没有人称和数的变化.不论主语是第几人称,不论主语是单数还是复数,情态都词都无形式变化;
②.不能单独充当谓语.情态动词必须与一个实义动词一起构成复合谓语,并且这个实意动词要始终是动词原形.
③.变为否定句时只需在情态动词之后加not.
④.变为疑问句时只需将情态动词提到主语的前面.
这是情态动词的共性,作为情态动词的need当然也具有这些共性.了解了这些还不够,还要掌握作为情态动词need的一个个性,就是它只能用于否定句和疑问句,或用于由if或whether引导的宾语从句中,一般不能用于肯定句.理解了这些之后,我们便可以如此区分need的词性了:只要need后面跟的是动词原形,它就是情态动词.这时,变否定,只需在其后加not;变为疑问句,只需把它移主语的前面.例如:
9).Need I type this letter again?我需要重新录入将这封信吗?
10).There is enough time.You needn’t hurry.有的是时间,你不必着急.
11).The president wondered whether he need send more soldiers.总统不知道他是否要增兵.
12).---Must I hand in my homework now?现在我必须交作业吗?
---No,you needn’t.不,你不必.
三.用作名词
need作为名词,含义为“缺乏,需要”;其复数表示“基本需要”.要掌握两个词组:in (great) need of(急需) 与meet the needs of(满足……的需要).例如:
13).There’s no need for you to try again.你不必再尝试了.
14).The factory is in great need of funds.那家工厂急需资金.
15).This house of the 1790’s can even meet the needs of the 21st century.这栋18世纪90年代的房子甚至能够满足21世纪的需要.
四.自我检测
现在可能你很想知道你是否完全掌握了need的用法,请做下列练习,进行一次自我检测,将正确答案填写在题前的括号中.

A.don’t need B.needn’t C.need D.doesn’t need
