need to do sth实义动词

needn`t do sth情态动词
don`t need实义动词
“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 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

(sb) need to do 的主语是人
（sth)need doing = need to be done 主语是物
too much 修饰不可数名词
too much time, too much money
much too 修饰形容词和副词
much too difficult

need to do 需要做某事

E.G:I need to wash my clothes.
My clothes need washing.
need doing = need to be done
I need to mend my bike.
My bike needs mending...

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。
e.g. There is too much snow and ice. 冰雪太多。
It’s much too cold.天太冷。
