1、2两句放在一起讲
两句的句意都是指别人原来不必要做的事而在现实中已经做了,在1句中a选项的意思中带有批评的味道,语气较重.2句中所指之事实已经做的了所以选b
3句我认为是虚拟语气的用法,所以选d
NEED用法
1need(需要)作及物动词,后面可接不定式或名词化的动名词作宾语.接不定式时表示主动;接名词化的动名词时有被动的含义,相当于不定式的被动语态.
You need to finish your homework.
你得完成你的作业.
2need(必须)作情态助动词,用在否定句和疑问句中.此时need本身不变形,后面的动词也要用原形.
You need not worry about this.
你不必为此担心.
Need he come here?
他有必要来吗?
3need(需要,必要)作名词,且可构成短语如:be in need of(需要...),a friend in need(患难之交),in need(家境困难).
There is no need to worry at all.
根本没有必要担忧.
I''ll come when you are in need of help.
在你需要帮助的时候我会来的.
4作助动词用:
用在否定句和疑问句中.否定形式常缩写为needn''t.
没有人称变化,即第三人称单数时不加-s.
后接动词原形,可指现在或将来.
need+have+p.p.表示对过去某事是否必要的看法,常含有责备之意.
