gwd-9-19

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]

为什么E错？看了老贴，没有人问，是因为whose 么？

if...and if...的平行正如joe11所言。whenever与if就是不平行嘛，mm不要太在意平行的好不好，结构与成分完全一致的平行是ETS最prefer的。参见og有一道讲“年轻人与他们的祖辈有着共同的目标”和“有些人以前该死但没有死活到了晚年”（题号记不得了）这两道题，mm一定会对平行有更深刻的理解。

这里还有个问题是数的一致余冠词的用法。the corporation whose employees commit a crime, commits a crime, whenever the employee acted。前面是复数，那后面这个冠词the必须指代前面涉及过的单数employee。再看A a corporation commits a crime whenever one of its employees commits a crime, if the employee acted ,是不是指代得很清楚呢？不要忽略了a/an/the/one这些小词与名词的数，考点密集呵
