3. 虚拟语气表建议:He suggested that we should leave at once.
4. 虚拟语气表要求:The teacher required that they should keep the

重点二 虚拟语气在条件句中的运用
【真题实战】
If the bus to the airport hadn't been late , we _________________(catch) the plane. (2018年)
解析:选D,此题可通过从句的hadn’t been late判断出从句提出与过去事实相反的假设,此为虚拟条件句,因此主句的谓语应使用would /could /should /might+have+动词过去分词的形式。句意为:如果去机场的巴士没有晚点,我们就会已搭上飞机了。
caught B. had caught
C. would catch D. would have caught
重点二 虚拟语气在条件句中的运用
英语中的条件状语从句可分为真实条件句和虚拟条件句。真实条件句表达一种真实的条件和可能实现的结果,而虚拟条件句的从句提出一种与客观现实不相符或不存在的假设,主句产生的结果因而也是虚假的。虚拟条件句按照时间的不同,可分为以下三种:
类别 结构 例句
与现在事实相反 从句 If+主语+动词过去式(be用were) If she had time, she would do it.
If Tom asked me, I would lend him the money.
If I were you, I would give
