It was ____weather that they decided to go out for a picnic.

题目

It was ____weather that they decided to go out for a picnic.
A such fine B so fine the
A我敢肯定是正确的,但B也好像没错啊,so 后面的确有加形容词fine 难道是It was so fine the weather is that they decided to go out for a picnic.但怎么可能出现两个谓语is?

答案

可以说so fine a day,但不能说so fine weather或者so fine the weather.so+形容词之后必须是不定冠词加名词,或者只有形容词,没有名词中心词,如the weather was so fine.
语言习惯而已,记住就行.
