關閉窗口 【分析】最佳答案選 D。insist后的從句謂語有時用“should+動詞原形”這樣的虛擬語氣，有時不用，具體要看該謂語動詞所表示的含義。一般說來，若該謂語動詞所表示的動作尚未發生，或尚未成為事實，則用虛擬語氣；若該謂語動詞所表示的動作已經發生，或已經成為事實，則要用陳述語氣。分析上題的句意，可知只有選D最合適。請做以下類似試題（答案選B）：
(1) The patient insisted that he _______ ill and _______ to the hospital.
A. wasn’t, wasn’t sent B. wasn’t, shouldn’t be sent
C. shouldn’t be, wasn’t sent D. shouldn’t be, shouldn’t be sent
(2) The man in prison insisted that he _______ nothing wrong and _______ set free.
A. should do, should be B. had done, should be
C. had done, had been D. should do, had been
(3) I advised that he ______ to the hospital at once, but he insisted that he ______ quite well then.
A. was sent; felt B. be sent; was feeling
C. he sent; feel D. should be sent; should feel
6. ______ smoking, he would not have got cancer in the lung.
A. Was he given up B. Had he given up
C. Did he give D. If he gave up
【陷阱】容易誤選 D。
【分析】正確答案應選B。之所以不能選D，是因為時態前后有矛盾。由于主句謂語是would not have got，這表明是對過去事實作出的假設，所以從句謂語應該是 had given up，而不是像D項那樣用一般過去時。另外，當虛擬條件句中有 had, should, were 等詞時，通常可以省略 if，并將 had, should, were 提前置于句首。又如：
Were they to cease advertising, prices would come down.= If they were to cease advertising, prices would come down. 如果他們停止做廣告，價錢會降下來。(www.hz123456.com)
