Who my dictionary?I don’t know.It on your desk just now.
Who my dictionary?
I don’t know.It on your desk just now.
A took had been
B has taken ,was
C has taken ,has been
D took was
Who ?my dictionary?
I don’t know.It ?on your desk just now.
A took had been
B has taken ,was
C has taken ,has been
D took was
答案：B has taken ,was
解析 just now.用过去时
再问： 如果强调刚刚还在桌上 为什么不能用has been呢？还有为什么不能用AD呢？A是到刚刚那段时间还在桌上，过去完成时。
再答： 解析：1、Who ？？my dictionary？（这一句话，表示词典不在这而了） 2、I don’t know.（表示现在：我不知道。） 3、It ？？on your desk just now. （just now刚才，表示过去，有强调过去，按照英语语言习惯：just now用于一般过去时句中。） 另外，语言都有一个约定俗成原则，力求简单明了。 1、能用一般现在时表达清楚，尽量避免用其它形式表示（现在进行时，现在完成时等等） 2、能用一般过去时表达清楚，尽量避免用其它形式表示（过去进行时，过去完成时等等） 3、能用一般将来时表达清楚，尽量避免用其它形式表示（将来进行时，将来完成时等等） 希望对你学习有帮助。
