典例剖析
[例1](2004年遼寧,26)Maybe you have been to many countries,but nowhere else ______ such a beautiful palace.
you find B.you could find
C.you can find D.could you find
剖析:第一個(gè)分句中使用現(xiàn)在完成時(shí)態(tài),第二個(gè)分句常使用現(xiàn)在時(shí),排除B、D項(xiàng);含有否定意義的副詞放在句首時(shí),該句要用部分倒裝,排除C項(xiàng)。
答案:A
[例2](2004年福建,28)-How do you ______ we go to Beijing for our holidays?
-I think we’d better fly there.It’s much more comfortable.
A.insist B.want
C.suppose D.suggest
剖析:根據(jù)本句的謂語用原形這一現(xiàn)象可知用suggest。按句子結(jié)構(gòu)的劃分,這句話是含有插入語的特殊疑問句。插入成分的動詞是suggest時(shí),主句的謂語動詞多用should+動詞原形,should可省略。insist一詞也有該用法,但與句意不符。如果用suppose之類的詞作插入語,此句的謂語應(yīng)該是將來時(shí)。
答案:D
[例3](2004年福建,32)-I’ll tell Mary about her new job tomorrow.
-You ______ her last week.
A.ought to tell B.would have told
C.must tell D.should have told
剖析:情態(tài)動詞+have+過去分詞說明的是過去。根據(jù)狀語last week和本句意義,應(yīng)該選should have told,意為“本應(yīng)該上星期告訴她,但你卻沒有”。
答案:D
[例4](2004年廣東,35)-Do you mind if I open the window?
-______ I feel a bit cold.
A.Of course not. B.I’d rather you didn’t.
C.Go ahead. D.Why not?
剖析:由I feel a bit cold看,答話者不愿開窗。A、C、D都表示“要開窗”的意思。
答案:B
