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,疑问句,条件句.例如:1.You needn't do it again.你不需要重复做了.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.四、其一般疑问句的答语,肯定用must,否定用needn't.Need I go with her?我需要和他一起去吗?Yes,you must.是的,你需要去.No,you needn't.不,你不必去.编辑本段“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 例如:The room needs cleaning = The room needs to be cleaned.房间需要打扫了.另外,“need”作实义动词时后还可以直接跟名词.请看下面的例子:It is a question that needs very careful consideration.这是一个需要慎重考虑的问题 很简单的方法区别情态动词与实义动词:当need为情态动词时,意思是“必要”,否定为"needn't",后面大多接动名词,表示动作; 当need为实义动词时,意思是“需要”,否定为"don't need",后面大多跟名词.一、need表示“需要”或“必须”,通常用于否定句,疑问句,条件句。例如: 1.You needn't do it again.你不需要重复做了。 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。 四、其一般疑问句的答语,肯定用must,否定用needn't。 Need I go with her? 我需要和他一起去吗?

need作为动词有两种用法,可以作情态动词和实义动词,详细用法如下:
(1) 其后接动词原形
通常只用于否定句或疑问句,一般不用于肯定句;本身无词形变化。
如:Need he do it all at once? 他需要马上就做吗?
You needn’t make two copies. One will do. 你不用打印两份。一份就够了。
(2) needn’t可用作以must开头的疑问句的否定回答。
如:A:Must I go there now? 我必须现在去吗?
B:No, you needn’t. 不必了。(也可用 No, you don’t have to, 但不能用 mustn’t
注意以下一般疑问句的回答:
A:Need I type this letter again? 这封信需要我再打一遍吗?
B:No, you needn’t. 不,你不必了。
B:Yes, you must. 是的,你必须再打一遍。
B:Yes, you need.(此回答错误,因为用作情态动词的need不能用于肯定句中)
(3) 当要谈论过去情况时,其后要接动词完成时。
如:You needn’t have come in person. 你当时不必亲自来的。
Need you have paid so much? 你当时真需付那么多钱吗?
(1) 既可用于否定句和疑问句(需要借助助动词do的适当形式),也可用于肯定句(注意有词形变化),为及物动词,其后可跟名词、代词、不定式等。
如:How much money do you need? 你需要多少钱?
You don’t need to stay. 你没有必要留下。
This plan needs careful thought. 这个计划需要好好考虑。
We need to be especially careful. 我们需要特别小心。
(2) 当need表示客观上的需要时,其后可接不定式或动名词,注意:接动名词时要用主动形式表示被动含义。
如:这个句子需要解释。
正:This sentence needs explaining [to be explained].
误:This sentence needs to explain [being explained].
再比较以下句子,第二句中的 mending虽为主动形式,也表示被动含义:
我得把我的外套去补一下。
正:I need my coat mended.
正:I need my coat mending.
(1) 一般说来,用作情态动词和用作实义动词,在意思上没有多大差别,只是用法上差别较大。如:
He needn’t come. 他不必来。
He doesn’t need to come. 他不必来。
但是,在个别情况下两者在意义上也有差别。如:
He needn’t be told. 没有必要告诉他。
He doesn’t need to be told. 不需要告诉他了。(即他已知道了)
(2) 比较 didn’t need to do 与 needn’t have done:前者通常表示因为没有做某事的必要,所以没有去做;后者通常表示某事已经做了,但后来觉得没必要去做,含有责备或遗憾之味。如:
I didn’t need to get up early this morning, so I stayed in bed until 9 am. 今天早上我不必早起,所以我一直睡到上午9点钟才起床。
I got up early, but I needn’t have done so, because I had no work to do that morning. 我起床起得很早,但我本来不必起那么早的,因为我那天早上没什么事做啊。
need 作行为动词:可用于疑问句、否定句和肯定句。作为动词的need后可接动名词的主动式表示被动含义。 need 还可作名词:表示“需要, 必需, 必需品”等。
