Question

—I hear Jane has gone to the Holy Island for her holiday.

—Oh, how nice! Do you know when she ________?

A. was leaving                  B. had left

C. has left                        D. left

Answer 1

D

解析:

因為Jane已經度假去了，“離開”此地就當然是在此之前的過去某個時間了，所以用一般過去時，選D。另外，when通常都不與完成時連用，排除B和C，A也與語境不符。
