Question

【題目】I can't get into the office because I ________ my keys at home.

A.leaveB.am leavingC.have leftD.had left

Answer 1

【答案】C

【解析】

句意：我不能進(jìn)入辦公室，因為我把鑰匙落在家里了。

考查時態(tài)辨析。leave意為“落下”。A. leave一般現(xiàn)在時；B. am leaving現(xiàn)在進(jìn)行時；C. have left現(xiàn)在完成時；D. had left過去完成時。根據(jù)題意可知此處是說過去把鑰匙落下這件事對現(xiàn)在造成了影響，用現(xiàn)在完成時。故選C。
