speak of和speak的区别是什么?详细说明用法.

1：refer to强调的是参考,涉及,指的是,暗示.
Are you referring to women?你指的是女人?
2：speak of 说到... 通常是用在重复他人说的话.比如你说起关于女人的事,我会说：
Speaking of women... 说起女人...【常用在句首.】
3：come to【一般用在从句中】,也表示提到.
When it comes to women...(一提到女人...）

没人敢提及它.
dared 用过去式,表示是过去没人敢提及,现在可能敢了.
但这里没有时间状语,感觉怪怪的.
还是
No one dare speak of it.
更好吧

Talk of the devil and he will appear.
