Mathor can't imagine what she is doing at the moment .为什么要用what she is doing 进行时啊
问题描述：
Mathor can't imagine what she is doing at the moment .
为什么要用what she is doing 进行时啊
答
imagine doing sth
答
at the moment 是在那时的意思
答
Mother can't imagine what she is doing at the moment .
我们大家都知道运用过去时还是现在时一般都是根据时间状语确定的,
那我们这句话的时间状语是at the moment “此刻；当时” 很明显是进行时啊!
翻译过来就是：母亲不能想象她当时正在做什么.
整个句子中mother是主语,imagine是谓语,what she is doing 是宾语从句,at the moment是状语
答
at the moment是此时的意思，也就是现在，所以前面应该是动词的ING形式
