A. so; either
B. such a; either
C. such a; both
D. such ; either
答案：
A. so; either
B. such a; either
C. such a; both
(答案→)D. such ; either
解析：此题重点考查so…that …和such …that…的区别。such…that作“如此…以致”解，连接一个表示结果的状语从句。与so…that 意思相同，但用法不同。如：so…that这一结构中，so后边可加形容词或副词， 而such后边要用名词（这个名词前面可以带形容词，也可以不带）。Either of +名词复数表示两者中任何一个
