Q28:

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.

1. a corporation commits a crime whenever one of its employees commits a crime, if the employee acted
2. a corporation is committing a crime whenever one of its employees committed a crime, if those employees were acting
3. corporations commit a crime whenever one of its employees does, on the condition that the employee acts
4. corporations commit crimes whenever an employee of those corporations commit a crime, if it was while acting
5. the corporation whose employees commit a crime, commits a crime, whenever the employee acted

   Answer:

此题给的答案是A, 但我看不明白.
a corporation...whenever...,if...and if....这算什么结构?

毫无疑问"a corporation..."是主句, "whenever..."是状语从句. 然而两个"if..."算什么成分?
从句套从句?第一个if前似乎多了个逗号.
三个从句并列?应该把并列的部分放到同一个if从句中才对呀.

E似乎没错嘛!  the corporation (whose employees commit a crime), commits a crime, [whenever the employee acted
   within the scope of his or her authority] and [if the corporation benefited as a result]意思是说"当职员的行为在其职权范围内 并且 如果公司从中获利,   那么该公司(其职员有犯罪行为的公司)就犯罪了".

其中主句是 "the corporation commits a crime", 从句是两个并列条件: "whenever..."和"if...", 而"whose..."是corporation一词的定语从句.
而且从句中的"act"就是指代主句中的"commit a crime".
都讲得通.

请NN们给把把脉!

E中的whose employees与the employee不对应,故错.

A正确,是并列结构.
