问题描述：
It is such a fine weather .和It is such fine weather 哪个对
答
第二个对.
weather是不可数名词,所以其前面不能加不定冠词a.
补充二楼如下：
1）如果修饰可数名词单数,则：such a/an + 形容词 + 名词 = so + 形容词 + a/an + 名词
如：such a clever boy = so clever a boy
2）如果修饰可数名词复数,则so many/few + 名词 或 such + 其他形容词 + 名词
如：so many people；such good books
3）如果修饰不可数名词,则so much/little + 名词 或 such + 其他形容词 + 名词
如：so little water；such fine weather
