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：根據(jù)語境可知此句的主語是Mary，是單數(shù)，故謂語動詞也要用單數(shù)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(xù)性，故選B。
考點：主謂一致
點評：有關(guān)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(shù)形式的名詞詞組作主語時，一般謂語動詞用復(fù)數(shù)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(fù)數(shù)形式應(yīng)由連接詞前的名詞而定。
