Question

Though they are______little children , they have worked out _______many difficult math problems.

A．so; so

B．such; such

C．so; such

D．such; so

Answer 1

D

试题分析：such是形容词，修饰名词，意思是如此的这样的；so是副词，修饰形容词，副词，意思是如此这样。句意：尽管他们是这么小的孩子，他们已经解决了如此多的数学难题。结合语境可知前一空用形容词形容词修饰中心词children，后一空用副词修饰形容词many，故选D。
