In theoffice I never seem to have time until after 5:30 p.m.,__________ many peoplehave got home.
A. whosetime B.that
C.on which D.by which
试题答案
答案：D
提示：这是一个非限制性定语从句。介词by的意思是“到那时为止”。这句话的意思是：“在办公室里，我似乎直到下午5：30才有空，那时，许多人都已回到家了。”又因其后为完成时态，所以用by which，介词on后接具体日期，如：on Sunday, on the mooring of July 1,onJune 1等。
