常见题型:choice、fill、short
例题 1
If he ______ (follow) the doctor's advice last week, he ______ (recover) by now. (用所给动词的适当形式填空)
解答
had followed; would have recovered
解析:
本题为混合虚拟条件句。从句时间状语为last week,表示对过去的虚拟,故用had followed;主句时间状语为by now,表示对现在的虚拟,故用would have recovered(强调结果持续到现在)或would recover(强调当前状态)。根据上海高考常见答案倾向于“would have recovered”体现完成性。

例题 2
It is strange that he ______ (refuse) such a good opportunity at that time. (用所给动词的适当形式填空)
解答
该空格位于“It is strange that...”引导的主语从句中。此类结构常用虚拟语气,形式为 should + 动词原形;当从句所述动作发生在过去时,则用 should have + 过去分词。句中 at that time 表示过去时间,refuse 所表示的动作已经发生,因此应填 should have refused。完整句子为:It is strange that he should have refused such a good opportunity at that time. 此处 should have refused 表达对过去已发生行为的惊讶或意外,含义相当于“他竟然拒绝了这么好的机会”。
解析:
该题考查名词性从句中的虚拟语气。It is strange that...句型中,从句谓语常用“should + 动词原形”,should可省略。但本句中有at that time表示过去时间,因此应使用should have refused(表示对过去事实的虚拟,带有“竟然”的意味)。
