①Parents should pay attention to the TV programs.
②Their kids watch the TV programs
两种写法,都要把电视节目作为先行词：
a.主动句，可合写为：
Parents should pay attention to the TV programs which their kids watch.
b.被动句，可合写为：
The TV programs which their kids watch should be paid attention to by their parents.
两句中的which可换为that，或直接省略，原因是做宾语
