-- Why do you look so worried ?
-- My MacBook Pro broke down and my paper _____ unfinished ever since.
A.leftB.was leftC.has been leftD.has left
C

試題分析:考查時(shí)態(tài):句意:--你為什么看起來(lái)這么擔(dān)心?-- 我的MacBook Pro壞了,我的論文自從那時(shí)還留在那里沒(méi)有完成。從ever since可知是現(xiàn)在完成時(shí),從paper和leave的關(guān)系,可知是被動(dòng)。選C。
點(diǎn)評(píng):時(shí)態(tài)題的考查關(guān)鍵是抓住句子的上下文含義和句中的時(shí)間狀語(yǔ)。要根據(jù)時(shí)間狀語(yǔ)來(lái)選擇合適的時(shí)態(tài),在平時(shí)的學(xué)習(xí)中要注意積累有關(guān)時(shí)態(tài)的用法和各種時(shí)態(tài)的特殊之處。如since, so far等經(jīng)常與現(xiàn)在完成時(shí)連用。
