【典例精析】
1.（2007 全国卷II， 8） _______ he had not hurt his leg, John would have won the race.
A. If B. Since C. Though D. When
【解析】A 有题干可知，“若不是他伤了腿，约翰就能赢得比赛了”，运用了虚拟语气，故用if。
2.（2008山东卷, 24） Thank you for all your hard work last week. I don’t think we ____ it without you.
A. can manage B. could have managed
C. could manage D. can have managed
【解析】 B 此题考查情态动词表示虚拟意义的用法。I don’t think…是否定前移。意为：我认为没有你我们本不能做成这件事的。此题关键是要根据句意知道是虚拟语气，其基本形式是情态动词（过去式）+have done,所以其他选项皆可排除。
【答案】B
3（09福建）. But for the help of my English teacher, I____the first prize in the English Writing Competition.
