The story was written in easy English even the seven-year-old boy could understand it.

A. very, that

B. so, that

C. such, that

D. too, to

答案：

A. very, that

B. so, that

(答案→)C. such, that

D. too, to

解析：very, that英语中无此搭配用法；so, that如此……以至于，so后面接形容词或者副词；such, that如此……以至于，such后面接名词；too, to太……而不能。句意：这个故事是以如此简单的英语写的，以至于七岁的孩子都能读懂。easy English中心词是English，名词，故选C。
