英语情态动词 :
9. A.此题易误选为B或C.这是因为受了思维定势的影响引起的,因为前面句子中的must这个词,许多人就想当然地选择了B项。其实,这里应该选择A项,句意为:你必须每月回来一次。好的,我会的。
10. C.maybe是副词,意为可能;也许,在句中作状语。may be是两个不同的词,其中,may是情态动词,be是连系动词,在句中作谓语。
11. A.neednt表示没有必要;may意为可以.
12. A.考查情态动词。由后文但他还不能肯定可知,他可能会来,所以选A.can表示推测的可能,多用于否定句或疑问句中,must是有把握的肯定推测,一定.
13. A.考查情态动词。mustnt千万不,绝不能,一定不要;cant不能;shouldnt不应该;neednt不必要。
英语情态动词 :
14. D.考查情态动词。请求允许用may或can.
15. C.考查情态动词。否定回答must,表示不必用neednt,排除A和B.又表示允许可以,用may或can,所以A正确。若用must与前面neednt相矛盾。
