帮忙解释一下下面这个语法点吧
It can be seen that the purpose of study still is work efficiently that have not necessary relate to education level. 这个句子中work应该用什么形式?为什么
As far as I am concerned, the criteria of salary payment is worker’s ability and the contribution to society progress. 这个句子里中payment后应该用is还是are?为什么

应该用working.
前面有系动词is,后面又用副词efficiently修饰,所以只能采用动名词形式working.

应该用are.
因为句子主语是criteria,为复数形式,所以be动词也用复数形式are.
