问题补充：

--- Yes, it is that I’d like to take a walk．
A. such a nice weather
B. so a nice weather
C. such nice weather
D. so nice weather
答案：
A. such a nice weather
B. so a nice weather
(答案→)C. such nice weather
D. so nice weather
解析：考察such和so用法。Such后面要接名词或者名词短语，而so后面要接形容词或者副词。但是当such后面接a/an+形容词+单数名词时=so+形容词+a/an+单数名词。本句指的名词weather是一个不可数名词，不能用a修饰。句意：—天气真好啊！—是的。天气如此之好，我想出去散步、故C正确。
