Our teacher told us that we never forget it.
A. so an interesting joke
B. such an interesting joke
C. so interesting a joke
D. such interesting a joke

A. so an interesting jokeB. such an interesting joke(答案→)C. so interesting a jokeD. such interesting a joke解析：so后面要紧跟形容词，然后再跟名词，如果该名词为可数名词的单数形式，那么要在名词前加不定冠词；such要跟名词，如有形容词修饰，且该名词为可数名词单数时，其结构为:such+a/an+adj.+n.。

和我的回答一样，看来我也对了
