单词精讲:
be to do sth
约定,注定,必定“要做什么.指的人是对未来的一种计划,安排。
如:They were to meet at the usual place.
他们约好在老地方见.
be about to do sth 正要做什么,如:
He was about to leave when the phone rang.
他正要离开就在这时电话响了.


  If it were me(虚拟语气的用法)
1、表示与现在事实相反的情况:  
从句:If 主语+过去时  
主句:主语+should/would/could/might+do  
eg:If I were you,I would take an umbrella.  
如果我是你,我会带把伞。(事实:我不可能是你)  
  If I knew his telephone number,I would tell you.  
如果我知道他的电话号码,我就会告诉你。(事实:不知道)  
  If there were no air or water,there would be no living things on the earth.  
如果没有水和空气,地球上就不会有生物。(事实:地球上既有空气也有水)  

  2、表示与过去事实相反的情况  
从句:If 主语+had+done  
主句:主语+should/would/could/might+have done   
eg:If I had got there earlier,I should/could have met her.
如果我早到那儿,我就会见到她(事实:去晚了)  
  If he had taken my advice,he would not have made such a mistake. 如果他听我的劝告的话,就不会犯这样的错误了(事实:没有听我的话)   

  3、表示对将来情况的主观推测  
从句:①if+主语+were to do 主句:①主语+should/would/could/might+do    ②if+主语+did/were ②主语+should/would/could/might+do  
   ③if+主语+should+do ③主语+should/would/could/might+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)  
  If there were a heavy snow next Sunday,we would not go skating.   如果下周日下大雪,我们就不能去滑冰了。(事实:下雪可能性很小)


  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。这种条件句叫错综条件句。  
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。  
eg: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  
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。

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,即把were,should,had等词置于句首,这种多用于书面语。eg: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。

6、 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。  
②省略主句 If I were at home now. 要是我现在在家里该多好啊。

7.注意,在虚拟语气的从句中,动词be的过去时态一律用were,不用was。       eg:If I were you,I would go to look for him. 如果我是你,就会去找他。
