【题目】It is difficult for us to imagine ______ life was like for slaves in the ancient world.
A．where B．what C．which D．why
在线课程【答案】B
【解析】句意：对我们来说很难想象古代世界奴隶们的生活是怎么样的。本题考查名词性从句连接词。动词imagine后面含有一个宾语从句______ life was like for slaves in the ancient world，空格处作宾语从句中like的宾语，能作宾语的只有B、C项，但which表示“哪一个”，与句意不符，故选B。
