题目内容
17.You mean I was absent?No!I___at noon and I have been in the office since.( )A. | came back | B. | have come back | C. | was back | D. | have been back |
分析 你意思是我缺席了?不!我是中午回来的,而且自从那时我一直在办公室.
解答 答案A
由于and后的并列句是现在完成时,时间状语是since+过去时(at noon).所以came back的动作发生在过去,即at noon.故用一般过去式.所以选择A项.
点评 考查时态.主要要根据时间状语或句子意思判断时态,然后选择合适的谓语动词.
