Monica is not ______ chess player as we expected her to be.

Monica is not ______ chess player as we expected her to be.
A、 so a successful
B、 as a successful
C、 such successful a
D、 so successful a
【正确答案】：D
【题目解析】：该题考查的是so和such的用法区别。such修饰名词通常是such+a/an+adj+n，如名词是不可数名词或者复数名词，则不可用不定冠词a/an；so后面只能跟形容词或副词，即so+adj、so+adv；该题中只有D选项满足条件。
