　　　[示例]考题1　No one ____ say that he could see the Emperors new

　　clothes.

　　A. dare B. Needs C. Dared to D. need to

　　解析　根据提干要求表示过去的情况即那时没有人有胆量敢说他没看见皇帝的

　　新衣裳，因此应选Ｃ，因dare表示过去式是实义动词才合乎题意。

　　 考题２　You ____ bring many books back until next month.

　　A. need to B. Dare to C. Dare not D. neednt

　　分析　据题旨意，句子后用了until介词＋时间的介词短语作时间状语，那么前

　　面的动词bring是终止性动词应使用否定式表示没必要，而dare not意为不敢，

　　不合题意，所以正确答案是Ｄ。

　　 考题３　Tom wanted me to play truant this afternoon with him ,

　　but I ____ do so.

　　A. dared not B. Didnt dare to C. Not dare D. dare not

　　分析　据该题意也是说过去的情况，在Ａ项中dare作为情态动词不能用过去式，

　　Ｃ和Ｄ项均不合题意。答案Ｂ，是表示过去式，dare在这里作为实义动词前面

　　用助动词的过去，后面to 可以跟不定式，可断定适合题意，所以该题答案选Ｂ。

　　 考题４　Father sent me the book , so I ____ to him for it.

　　A. neednt write B. Neednt have written C. dare not write

　　D. dare not have written

　　分析　据题意：父亲把书寄来了，我本没必要给他写信，但信已写了。所以该选

　　项的Ｂ答案，此答案neednt接动词的完成式表示过去本来没必要做的事，而做

　　了，所以与该题达意。
