虚拟语气
if条件句中的虚拟语气
1．(2013·北京卷)If we________a table earlier，we wouldn’t be standing here in a queue.
A．have booked B．booked
C．book D．had booked
解析： 句意为：如果我们早些订位子，现在也就不用站在这里排队了。本题考查虚拟语气。分析语境可知if引导的从句是与过去事实相反的假设，因此选择D项。
答案： D
2．(2013·天津卷)If he had spent more time practising speaking English before，he________able to speak it much better now.
A．will be B．would be
C．has been D．would have been
解析： 句意为：如果他以前花更多的时间练习说英语，他现在就能说得更好些。本题考查虚拟语气。本句为错综时间条件句，即if从句与过去事实相反，主句与现在事实相反。与现在事实相反的主句谓语部分为“would/should/could/might＋动词原形”。
答案： B
3．(2013·江苏卷)I should not have laughed if I________you were serious.
A．thought B．would think
C．had thought D．have thought
