Question

一Where is Mr. Black? I haven't seen him for a long time.

一He _________Switzerland. He _________there for several months.

A. has gone to; has been to    B. has gone to; has been

C. has been to; has been    D. has been to; has gone

Answer

B

【解析】句意：－布莱克先生在哪儿？我很久没见到他了。－他去瑞士了。他在那儿几个月了。Have gone to意思是去了某地，指去了，未回来；have been to意思是去过某地，指去过，已经回来；have been in意思是在某地。好久未见到他，说明他去了未回来，用have gone to；后句指他在那儿几个月了，用have been in，副词there前不加介词，用have been。故选B。
