I got up early, but I __________ so,because I had no work to do that morning.
A. needn’t do B. needn’t have done C. didn’t need do D. didn’t need to do
此题应选B。为了弄清此题,首先我们要知道need有情态动词和实义动词两种用法。一般说来,这两种用法在意义上差别不大,但在用法差别较大:
他必须去那儿吗?
正:Need he go there? (need为情态动词)
正:Does he need to go there? (need为实义动词)
但有时候两种用法在意思上也有较大差别:
1. a. He needn’t be told. 没有必要告诉他。
b. He doesn’t need to be told. 不需要告诉他了。 (即:他已知道了)
2. didn’t need to do / needn’t have done:前者表示因为没有做某事的必要,所以没有去做; 后者表示某事已经做了,但后来觉得没有必要去做,含有责备或遗憾之味:
I didn’t need to get up early this morning,so I stayed in bed until 9 a. m. 今天早上我不必早起,所以我一直睡到上午9点才起床。
That computer was expensive,and what’s more,I
didn’t need to buy such a good one. 那台电脑很贵,况且我也没有必要买那样好一台电脑。
I was the first to get there. I needn’t have gone there so early. 我是第一个到那儿的人,我本来不必去那么早的。
