问题描述:

She must be looking forward as much to ________ from him as he himself is to ________ from her.
She must be looking forward as much to ________ fromhim as he himself is to ________ from her.
A.hear…hearing B.hearing…hear
C.have heard…hearing D.hearing…hearing

look forward to doing sth.是一个固定搭配.
这里的to是介词,所以后面的do形式为doing第二个空怎么解析?第二空前面有省略。
She must be looking forward as much to hearing from him as he himself (is looking forward) to hearing from her.
句子中省略了括号里的内容.第二空的to其实也是介词
