“I have to go,” she said, and with she hung up the phone.
A. it
B. that
C. which
D. what

A. it(答案→)B. thatC. whichD. what解析：考查代词辨析。that只指物，不指人，可替代可数名词或不可数名词，具有“特指”性质。指的是同类事物中的另一样东西，即同类异物。如：The library of our school is bigger than that of yours.(that代替的是另一个图书馆。)；it代替上文所提到的名词时，是指同类事物中的同一样东西，即同类事物。如：I have lost my pen. I'm looking for it.我丢了我的钢笔。我正在寻找它。此处的that代指前面所说的件事，题干中有and连接，排除which引导定语从句。从句不能与主句之间有连词连接，what只能引导名词性从句。故选B。

这个问题我还想问问老师呢
