I was surprised little birds could eat many insects in a short time.

A. that so; so; such

B. that so; such; such

C. that such; so; so

D. that such; so; such

答案：

A. that so; so; such

B. that so; such; such

C. that such; so; so

(答案→)D. that such; so; such

解析：这题考查so，such的区别，such后面接形容词+名词，当形容词是many，much，little，few（两多两少）的情况，用so，但如果little表示“小”的时候，还是用such，根据句意：我很惊讶这么小的鸟能在这么短的时间吃这么多的昆虫。选D。
