Question

—Tom says he is too tired to go on.

—He can’t be. He ____ for an hour.

A. just worked　 B. has only been working

C. has just worked D. had only been working

 

Answer 1

B

句意: ——汤姆说他太累了不能继续工作了。——他不可能太累, 他刚刚工作了一个小时。说话者表示“到目前为止, 他刚刚……”, 故用现在完成时, 此外说话者又表示“抱怨”的语气, 故用完成体, 所以, 本题应该用现在完成进行时。
