【例1】(福建模擬)only after my friend came_________.
a.did the computer repair b.he repaired the computer
c.was the computer repaired d.the computer was repaired
提示:only加狀語放在句首，句子要用倒裝語序。故排除b、d兩項(xiàng)。computer與repair之間應(yīng)該為被動(dòng)語態(tài)。選項(xiàng)c符合上述要求。
答案:c
講評(píng):注意掌握特定的句型結(jié)構(gòu)。
【例2】(重慶模擬)i was on the highway when this car went past followed by a police car.they _________at least 150 kilometers an hour.
a.should have been doing b.must have been doing
c.could have done d.would have done
提示:must have been doing表示對(duì)過去正在發(fā)生的事情的肯定的推測(cè)，意為“必定正在……”因?yàn)樯暇湔f“我看到一輛警車緊跟著飛速而去”，所以下文我自然對(duì)此作出的推測(cè)相當(dāng)肯定。其余選項(xiàng)均無此用法。
答案:b
講評(píng):考查情態(tài)動(dòng)詞表示推測(cè)。從語境分析，此處推測(cè)過去那時(shí)一定在做某事。
