问题补充:
—I wonder if you could go with me to the supermarket.
—Sorry. I my experiment report all the morning and haven’t finished yet.
A. write
B. was writing
C. have written
D. have been writing
答案:
A. write
B. was writing
C. have written
(答案→)D. have been writing
解析:考查时态。本意的关键词是all the morning整个早晨,该时间状语常常与现在完成进行时连用。句意:—我想知道你是否和我一起去超市.—对不起。整个上午我都在写实验报告,我还没有写完。根据句意说明草早上开始到现在一直都在写实验报告。故使用现在完成进行时表示过去发生的倒装一直持续到现在。故D正确。
