needs的用法

needs为副词,相当于necessarily, of necessity.must needs和needs must均可表示“必须,必定,不得不”,这层意义上可以通用;但must needs还可表示“偏偏,偏要”,含有讥讽、不满的意思,而needs must则一般无这层意思。例如:

I must needs go there now.

我现在非到那里去不可。(可用needs must)

Needs must when the devil drives.

情势所迫不得不那样。

She must needs go away when I want her.

我正需要她时,她偏偏离开了。(不可用needs must)

The telephone must needs ring when I went to bed.

我上床睡觉时偏偏有人来电话。(不可用needs must)

need指主语的主观特需情况而使之必要。need既可以作助动词,又可以作行为动词。作助动词时,need没有人称和数的变化,后接不带to的不定式(动词原形),否定式为needn't.作行动动词时,need同别的行为动词一样,有人称和数的变化,后接带to的不定式,否定式要在前面加don't(doesn't, didn't),疑问句用do (does, did) 提问。例如:

There need be no hurry, need there?

He need never know.(=He never needs to know.)

I need only add a few words.(= I only need to add a few words.)

比较:

Father sent me the book, so I didn't need to write to him for it.

父亲把那本书寄来了,所以我不必为此给他写信了。(信没写)

Father sent me the book, so I needn't have written to him for it.

父亲把那本书寄来了,所以我本不该为此再写信给他的。(信已写)

She didn't need to come.她不必来的。(实际也没来)

She needn't have come.她本来不必来的。(但却来了)

Note:

作助动词用时,need只用于疑问句中和否定句中,在肯定句中常用must, have to, should, ought to等。例如:

Need you do it right now? I needn't, but he must.

She doesn't need to be told.She has already known it.

(客观情况使得告诉她没有必要:她已经知道)

She needn't be told.We should keep it secret from her.

(主观上不愿告诉)

must not表示禁止,是说话人强有力的劝告或命令,意为“一定要,不准”。因此,在回答由must引导的问题时,如果是否定的回答,表示“不必,没有必要”,不能用mustn't,而要用needn't或don't have to.试比较:

You must not drive fast.你不能开快车。(路险或有速度限制)

You needn't drive fast.(时间充裕)

You must not tell others.(警告)

You needn't tell others.(没有必要)
