Question

【題目】—When did the Greens come to China?

—They_____ China for seven years.

A. have been in B. have been to C. have come to

Answer 1

【答案】A

【解析】句意：-Green一家人是什么時候來中國的？-他們在中國呆了七年了。have been in呆在某地；have been to去過某地；have come to已經(jīng)來到某地。句中for seven years表示一段時間，故這里應(yīng)用have been in China，是系表結(jié)構(gòu)，表示狀態(tài)，可以持續(xù)。故選A。come是瞬間性動詞，不能和一段時間狀語搭配使用。
