问题 In this experiment, they are wakened several times during the night, and asked to report what they________.
选项 A、had just been dreaming
B、have just been dreaming
C、are just dreaming
D、had just dreamt
答案B
解析 在这个实验中，他们在夜间被数次唤醒，并被要求报告他们刚刚做了什么梦。动词时态题。and后面的省略句补充完整应该是“they are asked to report+what从句”，主句的时态是一般现在时，他们做梦是醒之前正在做的，因此从句用现在完成进行时，故B为正确答案。A项选项是过去完成进行时，由于主句的时态是一般现在时，所以“做梦”这件事不是过去的过去，故排除；C项选项是现在进行时，不符合题意；D项选项是过去完成时，为错误选项。
