90.Since 1986, when the Department of Labor began to allow investment officers’ fees to be based on how the funds they manage perform, several corporations began paying their investment advisers a small basic fee, with a contract promising higher fees if the managers perform well.
(A) investment officers’ fees to be based on how the funds they manage perform, several corporations began
(B) investment officers’ fees to be based on the performance of the funds they manage, several corporations began
(C) that fees of investment officers be based on how the funds they manage perform, several corporations have begun
(D) fees of investment officers to be based on the performance of the funds they manage, several corporations have begun
(E) that investment officers’ fees be based on the performance of the funds they manage, several corporations began
答案是D。如果看since这个时态标记,用现在完成时是没有问题的。但是记得begin是个瞬间动词,可以用现在完成时吗?
请教
我个人认为,BEGIN是可以用完成时的,只要不和FOR A PERIOD 这样的表示一段时间的短语连接即可。
有没有字典的解释?因为我手边没有好的字典
谢谢。
