Question

-My father with my grandparents _______ Shanghai.
-Really? _______ will they come back?

A．have been to; How soon	B．has been to; How long
C．has gone to; How soon	D．has gone to; How long

Answer 1

C

试题分析：句意：我的爸爸和我的爷爷奶奶去上上海了。真的吗？他们多久能回来？have gone to…“去哪后没有回来”；have been to…“去了哪之后回来了”。How soon“多久以后”，通常对in+一段时间提问；how long“多长时间”，对一段时间进行提问。故选C。
