2020广西省军队文职招聘考试大纲《英语》考点：虚拟语气(5)

1、表示与将来事实相反

　　从句：①if+主语+were to do

　　②if+主语+should+do

　　③if+主语+过去式(be动词用were)

　　主句：主语+should/would/might/could+do

　　eg：

　　If he should come here tomorrow，I would talk to him.

　　如果他明天来这儿的话，我就跟他谈谈。(事实：来的可能性很小，不可能)

　　If there were a heavy snow next Sunday，we would go skating.

　　如果下周日下大雪，我们就去滑冰。(事实：下雪可能性很小，不可能)

　　If she were to be here next Monday，I would tell her about the matter.

　　如果她下周一来这儿的话，我就会告诉她这件事的始末。(事实：来的可能性很小，不可能)

　　2、有时，虚拟条件句中，如果主句和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。这种条件句叫错综条件句。注：往往有明显的时间标志。

　　①从句的动作与过去事实相反，而主句的动作与正在发生的事实不符。

　　eg：

　　If I had worked hard at school，I would be an engineer now.

　　如果我当时在学校学习刻苦的话，我现在就是一个工程师了

　　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，我们就已经派他去北京了。

　　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。
