18、述與過去事實(shí)相反的情況要用would have done，故D項(xiàng)正確。] 2．D　[句意為：——天氣又熱又干燥。——是的。要是稍微下點(diǎn)兒雨，現(xiàn)在的情況就會(huì)更好一些！那樣我的蔬菜就不會(huì)死掉了。由條件句中的had rained可以推出這是與過去事實(shí)相反的虛擬語氣，但是主句有時(shí)間狀語now，所以用了與現(xiàn)在事實(shí)相反的虛擬語氣would be；最后一句話也是與過去事實(shí)相反的虛擬語氣，故用wouldn’t have died。] 3．A　[句意為：如果我知道這個(gè)電腦程序，就會(huì)節(jié)省大量的時(shí)間和精力。由上句“Had I known”可知，從句為與過去事實(shí)相反的虛擬條件句，省略了if。那么主句謂語形式應(yīng)為w

19、ould have done。] 4．B　[should表示“假如，萬一”。如：If you should need any help，here’s my number.萬一你需要幫助的話，這是我的電話號(hào)碼。] 5．D　[句意為：要是沒有他們的幫助，我們不可能及時(shí)完成那個(gè)計(jì)劃。but for要是沒有……，句子應(yīng)用虛擬語氣。又因計(jì)劃已經(jīng)完成了，所以用“情態(tài)動(dòng)詞＋現(xiàn)在完成時(shí)態(tài)”表示對過去發(fā)生的事情的猜測。] 6．D　[在聽完第一個(gè)說話者的話之后“我不知道Ann在住院”這個(gè)情況就已經(jīng)成為過去，所以要用一般過去時(shí)，因此可以排除B、C兩項(xiàng)；我去看她這個(gè)動(dòng)作發(fā)生在將來，是臨時(shí)決定要去做某事，沒有計(jì)劃和安排性，所以用will，不用be going to結(jié)構(gòu)，由此可以排除A項(xiàng)。故此題應(yīng)該選D項(xiàng)。] 對點(diǎn)訓(xùn)練 1．A　2.D　3.A　4.A　5.A
