Question

Mary, along with her parents            Hainan for a week and they will come back soon.

A．have been to

B．has been in

C．have been in

D．has been to

Answer 1

B

解析試題分析：句意：瑪麗以及她的父母已經(jīng)呆在海南一周了，他們將很快回來(lái)。have/has been to曾去過(guò)某地，have/has been in呆在某地；并且Mary為第三人稱(chēng)單數(shù)的主語(yǔ)，所以謂語(yǔ)動(dòng)詞也要用第三人稱(chēng)單數(shù)形式，故選B。
考點(diǎn)：考查現(xiàn)在完成時(shí)。
