The computer,___help we human beings have stepped into the information age,is regarded as an
接上：important invention in the 20th century.
A.which B.whose C.with its D.with whose
请问这个句子该怎么分析?我选A怎么不行?with whose help we human beings...这句话是不是有问题?我看得很奇怪,句中的we是不是应该是us才对?要不然句中不是有两个主语了吗——whose和we.还有,whose能和介词搭配吗?
