— You should let your children take more after-school classes.
—_____, you are right. But they should also have more time to relax.
A.To my surprise B.To a certain degree C.What’s more
B
【详解】
句意:——你应该让你的孩子多上课外班。——在某种程度上你是对的。但他们也应该有更多的时间放松。
考查插入语。A. to my surprise 令我吃惊的是;B. to a certain degree 在某种程度上;C. what's more 而且。根据“you are right. But they should also have more time to relax.”可知,“你是对的”并不是绝对的,只是在某种程度上。故选B。
