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(kāi)這兒兩天了，他們還沒(méi)回來(lái)。“not only…but also…”如果連接并列主語(yǔ)，句中謂語(yǔ)動(dòng)詞要根據(jù)“近主原則”確定，所以排除A；時(shí)間狀語(yǔ)是for two days，表一段時(shí)間，所以句中謂語(yǔ)動(dòng)詞要用延續(xù)性動(dòng)作動(dòng)詞，離開(kāi)（leave）的延續(xù)動(dòng)作動(dòng)詞是be away，故選C。
