请老师帮我看看这题.It was __that they planned to have a picnic.
A.such fine weather B.so fine a weather C.such a fine weather as D.such a fine weather 那个答案是B项,为什么不能选A呢,weather 为不可数名词吧.

是这样的, such后面只能跟不可数的名词比如weather 是一定不能加a的,如果后面可数了那么一律跟单数.
所有C,D不能选
so .. a 是一种固定搭配,不管可数与否,都要这样用.这没有办法.
A选项也可以选,我想不出任何原因不能选A,这题出的有问题
