A.had just been dreaming
B.have just been dreaming.
C.are just dreaming
D.had just dreamt
答案是选B,
答
从过去到现在一直进行，要用现在完成进行时，译为他们一直梦想的
答
没有选才对啊，主句用了一般现在时的被动，what的定语从句应为they was just dreaming.才对啊。[ttimes为times]， 既然被叫醒数次，就不可能一直在做梦。而是刚才正在梦到的。
答
翻译
在这个试验中,他们一个晚上被叫醒几次,要求说出他们刚刚正在做什么梦?
因为是 “正在做”==》所以用 being ==》排除D
因为从睡着到被叫醒是一段时间==》所以用现在完成时 （过去完成时表示过去的过去,这里不能用）==》排除 A.C
所以选 B
