选择题
It is only ______ you understand what your parents do to you ______ you can improve your relationship with your parents.
A．that; what
B．when; that
C．which; where
D．how; what
答案
答案：B
考查含有状语从句的强调句型。强调句型的结构为：it is+ 被强调的部分+ that+ 其它，此题中强调的是一个时间状语从句when you understand what your parents do to you，第二空用that，是强调句型的标志，所以选B。
