In one word,the hours ___ the children spend in their one-way relationship with television people undoubtedly affect their relationships with reallife people.A.In which B.when C.which D.that
答案c.理由：先行词是hours,可以考虑用which/when;如果用which,那么先行词在从句中充当主语或宾语；如果用when,则先行词在从句中充当时间状语.从整个从句中来看,这个hours应该是充当spend的宾语的,所以选用which
