Tom with his parents to America. They back in two weeks.
A. have gone; will come
B. has gone; will come
C. have been; have come
D. have been; come

A. have gone; will come(答案→)B. has gone; will comeC. have been; have comeD. have been; come解析：句意：汤姆还有他的父亲已经去了美国。他们两周后回来。结合语境可知前文描述的是现在已经完成的动作，故用现在完成时态。下文描述的是将来的动作，故用一般将来时态。Been to表示去过，已回来，故选B。

就是这个解释
