这道题为什么选C?

Question

___ the child expresses his interest in an activity, the stronger it will become.
A. The more frequent B. The frequenter
C. The more frequently D. The frequentlier
这道题我选的是A，可是答案是C，为什么A不对？请详细解释一下，谢谢！

Answer 1

因为frequent是形容词，frequently是副词，前半句按正常语序可以写为：The child expresses his interest more ____ in an activity，空格处显然该填个副词。所以答案是C

Answer 2

it will become stronger -形容词
the child expresses his interest in an activity ___--副词

这种强调句基本都倒装了，你恢复正常语序就好理解了

Answer 3

横线处需要一个副词来修饰动词express，排除AB。副词或形容词的比较级前面要加more来表达！
