可以啊，没有什么问题的
Simon is very regretful. If he had been more careful, he _____ such a big mistake. A．hasn"t .
D 试题分析：句意:西蒙是很后悔的，如果他再仔细点，他就不会犯这么大的一个错误。这里是虚拟语气，根据had been可以看出是对过去的虚拟，故主句用would have done的形式，根据句意故选D。点评：本题难度适中。虚拟语气是近几年高考的热点，虚拟语气的情况复杂，形式多样，需要考生牢记它们的不同的用法，再根据不同的语境分析句子应该用哪种情况的虚拟。这里是从句和主句都是对过去的虚拟。即学即练：Tell John not to leave the house unless he _____that the lights ______ .A. will make sure, turn off B. makes sure; are turned off C. will make sure; will turn off D. makes sure; will be turned off解析：B。第一空在条件状语从句中用一般现在时代替一般将来时；第二空所有的灯被关掉。
Hasbeeninvited和hasinvited用法区别
been，invited意思是已经被邀请了，这是现在完成时的被动语态。而invited是被邀请的意思，这有两层含义，第一层含义是被动，第二层含义是过去式现在完成时和过去时的区别是现在完成时强调已完成的动作对现在还有影响，而过去时只是强调这个动作在过去某个时刻已经完成了。
在句首时Having been invited和invited的区别？
都是非谓语，一个是强调被动+完成，另一个强调被动，区别是多了个强调完成，请多学习谓语为什么用完成，自然就懂非谓语为什么用完成，千万不要直接根据先后关系判断，主要看句型和语境。
had been invited 和were invited有什么区别？
选择A。该句的意思是大部分被邀请参加贝蒂生日宴会的客人是她的同学。注意：这里用到了定语从句，而定语从句又是对Most of the guests在起限定作用。邀请的主语是Betty,宾语是guests，guests是是被邀请的，所以原句可以这么理解，Most of the guests ___(who were )invited___ to Betty"s birthday party were her classmates. 定语从句的主语谓语可以省略，所以省略了就是原文的Most of the guests ___ invited___ to Betty"s birthday party were her classmates. had been invited 和were invited 的区别：had been invited 强调被邀请的过去完成的状态，而were invited 则表示被邀请的过去的状态。是时态的不同，导致选用的形式不同。
you"ve been reading articles about the tremendous damage done to life and pr
可以这样理解：you"ve been reading articles主干，后面about引导的成分来补充说明articles ，the tremendous damage 可以看成是主语，do可以看成是谓语，to life and property 可以看成是宾语，by earthquakes为宾语补足语，但是about引导的成分不是一个句子，故要用非谓语动词，把do变成done，用to是因为damage，表示受到damage的对象是life和property，其实如果改成about也可以，那样变成了damage的内容是life和property。所以这里的done to是分开的，不是什么固定搭配

农村出现了前所未有的繁荣--- the countryside appears a prosperity that had never been seen before
不能这么说。原因：1. 后面的句子用的是过去完成时态had done，过去完成时表示的是“过去的过去”，也就是说必须有“一般过去时“，才可能出现”过去的过去“这样相对性的概念。所以，前面的句子必须用一般过去时。简单说，过去完成时必须和一般过去时搭配才能使用。2. appear 的使用不妥当。有两种改的方法：1. The countryside showed a prosperity that had never been seen before.2.A prosperity that had never been seen before appeared in the countryside.
下面这句话中“complaining that he had been ill-treated by the police.”是做目的状语还是伴随状语？
1.第一个问题：complaining后面的句子做连接状语，表示前面动作进行完后，再做下一个动作。用ing形式，就不用逗号了，说明两个动作间隔很短，且接在一起。2.主句是A foreignor wrote to the Ombudsman complaining that he had been ill-treated by the police。而simply because he was a foreignor则是原因状语从句。
