were she here...

【问】 Were she here，she would support the motion.

如何分析这个句子?

【答】 这是一个无连词非真实条件从句，主要用于正式语体，其同义表达形式是：

If she were here...

同样：

Were the wire of a smaller diameter，its resistance would be increased.

＝If the wire were of a smaller diameter，its resistance would be increased.

如果金属丝的直径再小一些，它的电阻就会增大。
