provied 至于句首是什么语法现象

provied 应该为：provid
用来当引导状语从句的特殊连词
provid的现在分词和过去分词形式均可用作连词
如：
Providing/Provided that they think they are getting a bargain they will buy clothes they will never wear,furniture they have no space for.
只要他们觉得他们检了便宜货,就会买来永远不会穿的衣服和没有地方放的家具.)
其中的provied or providing(that)均表示"倘若"
此外还有：
如:Granted /granting that he has enough money to buy the house,it doesn't mean he is going to do
倘若他有钱买房子,并不意味着他将要买房子,此句中的granted or granting(that)均表示"即使,假定"
