嘿嘿，孩子们，今天我们来看看虚拟语气的另外几种用法吧：

　　4.有时，虚拟条件句中，结果主句和条件从句的谓语动作若不是同时发生时，虚拟语气的形式应作相应的调整。

　　①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。如：

　　If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会成为一个工程师了

　　If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。

　　②从句的动作与现在事实相反，而主句的动作与过去事实不符。如：

　　If he were free today, we would have sent him to Beijing. 如果他今天有空的话，我们会已经派他去北京了。

　　If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。

　　③从句的动作与过去发生的情况相反，而主句的动作与现在正在发生的情况相反。如：

　　If it had not been raining too much, the crops would be growing much better. 如果天不下太多的雨的话，庄家会长得更好。

　　If he had been working hard, he would be working in the office now. 要是他工作一直努力的话，他现在已进了办公室了。

　　5、 当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件从句要用倒装语序，即将were, should, had等词置于句首，这种多用于书面语。如：

　　Should he agree to go there, we would send him there. 要是他答应去的话，我们就派他去。

　　Were she here, she would agree with us. 如果她在这儿的话，她会同意我们的。

　　Had he learnt about computers, we would have hired him to work here. 如果她懂一些电脑知识的话，我们会已经聘用他来这里工作了。

　　6、非真实条件句中的条件从句有时不表达出来，只暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句，在多数情况下，条件会暗含在短语中，如without…., but for….等

　　But for his help, we would be working now. 要不是他的帮助，我们还会在工作呢。

　　Without your instruction, I would not have made such great progress. 要是没有你的指导，我不会取得如此大的进步。

　　We didn’t know his telephone number; otherwise we would have telephoned him. 我们不知道他的电话号码，否则我们就会给他打电话。

　　7、 有时，虚拟条件句中，主、从句可以省略其中的一个，来表示说话人的一种强烈的感情。

　　①省略从句

　　He would have finished it. 他本该完成了。

　　You could have passed this exam. 你应该会通过这次考试了。

　　②省略主句

　　If I were at home now. 要是我现在在家里该多好啊。

　　If only I had got it. 要是我得到它了该多好啊。、

　　答案：D 一般情况下虚拟语气还有混合条件虚拟语气，虽然是对过去的假设，但是主句用得却是现在事态，因为后面有一个now

　　2. He is a stupid man. But he acts as though he ___C____ a wise man.

　　     A. is  *B. wore C. should be  D. seems like

　　答案：C  as if/though后面引导的句子用主语+were 这里的were不能换成is/was ，无论主语是单数还是复数都不能
