单选题Inaword,thehours________thechildr

单选题 In a word, the hours ________ the children spend in their own way relationship with television people undoubtedly affect their relationships with real life people．A.in whichB.on whichC.whenD.that

D解析考查对句式结构的分析。主语为the hours，而谓语为affect，空格处所缺的词引导定语从句，修饰the hours，先行词在句中作spend的宾语，所以使用关系代词that。

这个问题我还想问问老师呢
