“need”双重角色的用法及其区别
“need”既可以作情态动词,也可以作实义动词,但是它们的用法不同。
作为情态动词的“need”的用法与其他情态动词“can”,“may”,“must”的用法基本相同:在限定动词词组中总是位居第一,没有非限定形式,即没有不定式、-ing分词或-ed分词等形式;第三人称单数现在时没有词形变化;情态动词之间是相互排斥的,即在一个限定动词词组中只能有一个情态动词。下面是“need”作为情态动词的用法:
一、need表示“需要”或“必须”,通常用于否定句和疑问句。例如:
1.You needn't do it again.你不需要再做了。
2.He needn't worry about it.这件事他无需担心。
3.Need he do this homework first?他需要先做这些作业吗?
4.Need they fill in the form?他们需要填表吗?
二、在否定句中,可以用need的否定形式+不定式完成体。例如:
1.We needn't have worried.其实我们不必要慌。
2.You needn't have mentioned it.你本来不必提起这件事。
3.You needn't have said that when he asked.当他问的时候,你其实不必要说。
三、needn't后的不定式间或也能用进行式或被动语态。例如:
1.He needn't be standing in the rain.他不必要站在雨中。
2.We needn't be waiting in this place.我们不必要在这儿等。
3.The hedges needn't be trimmed thisweek.本周树蓠不必要整修。
“need”作为实义动词时,通常用法是:
人+need +to do
物+need +doing
物+need +to be done
另外,“need”后还可以直接跟名词。请看下面的例子:
1.We need to collect the parcel before we leave for England.去英国之前,我们需要收拾好行李。
2.We need to tell him the truth.我们需要告诉他真相。
3.My car needs repairing.我的汽车需要修理。
4.The flowers need watering.这些花需要浇水。
5.His leather shoes needs to be mended.他的皮鞋需要修补。
6.Her room needs cleaning.她的房间需要打扫。
7.It is aquestion that needs very careful consideraton.这是一个需要慎重考虑的问题
很简单, 我们老师就让我们记了两个短语
1.too much trouble 太多麻烦 too much+名词
2.much too tired 太累了 much too+形容词
===========================================
too many,too much和much too,在使用时容易混淆。下面谈谈它们的用法:
这三个词语的主要区别在于它们的中心词以及它们所修饰的词不同。三者之中的前一个词都是修饰词,用来加强语气,后一个词是中心词。因此,在使用时只需要考虑后一个词的用法就行了。分述如下:
一、too many的中心词是many,用法与many相同,用来修饰复数可数名词。例如:
He's got too many questions to ask you.他有很多问题要问你。
They bought too many eggs yes- terday.昨天他们买了太多的鸡蛋。
Today,_____trees are still be- ing cut down somewhere in the world.(1999年辽宁)
A.much too B.too much
C.many too D.too many
答案是D。今天,在世界上有些地方仍有很多树木被砍伐。
二、too much的中心词是much,用法与much相同,用来修饰不可数名词。例如:
We both have too much work todo.我们俩都有很多工作要做。
She spent too much money on clothes.她花太多钱买衣服。
The teacher told him not to spend too much time playing games.老师叫他不要花太多时间玩游戏。
I'm afraid that I've given you too much trouble.恐怕我太麻烦你了。
He can't hear you because there is _____noise here.(1999年黑龙江)
A.very much B.too much
C.much too D.so many

Look!There's _____ice on the lake.(1999年成都)
A.too much B.much too C.a lot
答案是A。瞧!湖上有很多冰。
另外,too much还可作名词性短语,用作宾语;也可作副词性短语,在句中用作状语,修饰动词。例如:
You've given me too much.你给我的太多了。
I have too much to do every day, so I am very busy.我每天都有很多事情要做,所以我很忙。
He talked too much at the meet- ing,didn't he?他在会上讲得太多了,是吗?
Don't eat too much.不要吃得太多。
三、much too的中心词是too,用法与too相同,用来修饰原级形容词或副词。例如:
You're walking much too fast. Slow down.你走得太快了,慢点。
I'm afraid that this cap is much too big for me.这顶帽子我戴恐怕太大了。
It's much too cold outside.You'd better put on your overcoat.外面太冷了,你最好把大衣穿上。
The sweater is very beautiful,but it's _____dear.(1999年吉林)
A.too much B.much too
C.many D.more
答案是B。这件毛衣很漂亮,但太贵了。

A.big B.bigger
C.biggest D.the biggest
答案是A。这些鞋子我穿太大了。
==================================
too many 后面接可数名词,too much 后面接不可数名词,much too 后面接形容词
need to do 需要做某事
need doing 是需要被做有被动的意思
E.G:I need to wash my clothes.
My clothes need washing.
need doing = need to be done

too much中的中心词是“much”,后面跟不可数名词,意思是“太多的……”。too是用来加强much语气的。
much too中的中心词是“too”,后面跟形容词或副词,意思是“非常,太”。much是用来加强too的语气的。
