9、“非真实的事情及情况”，这种事情很可能不会发生，只是想象中的当前的情况，以及并未发生的事情。表示说话人的愿望、假设、猜测或建议，而不表示客观存在的事实，即表示与事实相反的情况。其结构是：在从句中用动词过去时，在主句中用条件式：would+动词原形（If+ subject+ V.(ed) ,subject+ would +do ）If I were you, I would do it at once.如果我是你的话，我会马上做这件事。If we had longer holidays, we would be perfectly happy.如果我们的假期再长一些，我们会相当愉快。（2）if从

12、e gets home early this evening, he will cook for us.如果他今晚回来早，他将为我们做饭。If I am free this weekend, I will play basketball with my friends.如果这个周末我有空，我将和朋友一起去打篮球。3、If在下面句子里的意思是“是否”，引导宾语从句。例如：He doesnt know if he should bring a present.他不知道是否应该带礼物。4、What if用来表示询问或提建议。意思是“如果怎么办？”例如：What if aliens should in
