GWD-9-Q19:

In many nations, criminal law does not apply to corporations, but in the United Stated today, a corporation commits a crime whenever one of its employees commits a crime, if the employee acted within the scope of his or her authority and if the corporation benefited as a result.

A. a corporation commits a crime whenever one of its employees commits a crime, if the employee acted

B. a corporation is committing a crime whenever one of its employees committed a crime, if those employees were acting

C. corporations commit a crime whenever one of its employees does, on the condition that the employee acts

D. corporations commit crimes whenever an employee of those corporations commit a crime, if it was while acting

E. the corporation whose employees commit a crime, commits a crime, whenever the employee acted [A]

答案是A没有疑问 请问if从句后为何用过去时啊 这与主句时态不一致

谢谢

难道对于从句的虚拟语气 主句无需有相应的虚拟语气吗

谢谢

单独的虚拟条件句可以存在。

但是好像没有虚拟主句+真实条件句的组合。

对  one of +复数名词 后面的verb也是复数；  the one of ＋复数名词，后面的verb 是单数 ！

从这个语法点 A错了！  应该是 commit

其次， a corporation commits a crime whenever one of its employees commits a crime, if the employee acted  既然有定冠词the，那么employee应该是复数更合理，与前面的 its employees 对称

相反，B没有这两个问题。

也许were给人感觉不好，但是were在这里应该还是可以表达be 的作用，而不是因为在if后面有“如果。。却与实际相反的意思”而改变原意

总之，A的错误在那，我选了B

以下是引用paraglider在2004-12-9 16:29:00的发言：
我看C对，A 有问题。

C不可能对，one of its employees就跟companies不对应

skyalan的講法有點confusing...

1. one of the employees主詞是one不是employees, 應該用單數形式

2. 因為前面在講 "如果員工當中的有人犯罪, 這個人..." 定冠詞是為了point out this specific employee, 還是應該用單數

關於前面所提到的虛擬, if the employee acted跟緊接著的if the corporation benefited 是很完美的平行...

C. corporations commit a crime whenever one of its employees does, on the condition that the employee acts

这里的does能这样用么,表示commits的省略
