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

試題分析：根據語境可知此句的主語是Mary，是單數，故謂語動詞也要用單數形式，故排除A和C。時間狀語for a week意思是一周的時間是段時間，故謂語動詞必須要用延續性，故選B。
點評：有關主謂一致的知識點要特別注意兩點：1.由and或both…and連接兩個單數形式的名詞詞組作主語時，一般謂語動詞用復數形式。2.由as well as，together with，besides, like，along with，with but，except，accompanied by，rather than，including連接兩個名詞作主語，謂語單復數形式應由連接詞前的名詞而定。
