Question

Not only his parents but also his brother _____ from here for two days. They haven’t been back.
A. have left
B. has left
C. has been away

Answer 1

C

試題分析：句意：不僅他的父母，他的弟弟也離開這兒兩天了，他們還沒回來。“not only…but also…”如果連接并列主語，句中謂語動詞要根據“近主原則”確定，所以排除A；時間狀語是for two days，表一段時間，所以句中謂語動詞要用延續性動作動詞，離開（leave）的延續動作動詞是be away，故選C。
