Question

【题目】—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一家人是什么时候来中国的？-他们在中国呆了七年了。have been in呆在某地；have been to去过某地；have come to已经来到某地。句中for seven years表示一段时间，故这里应用have been in China，是系表结构，表示状态，可以持续。故选A。come是瞬间性动词，不能和一段时间状语搭配使用。
