Question

Every means _________tried but without any result

Every means _________tried but without any result.
A. have been B. has been C. are to be D. is to be

Answer 1

根据without much result没有多少结果表唯察明句子是完成时，是指液茄已经完成的时态，又因为主语埋橘是every means 每一种方法，其实是单数，所以用has been

Answer 2

解:此处应选B。
means是一个固定单词配闷(不是mean的复数形式)，它的意思是手段；方式；方法，单复数同行。根据题干可知，every+c.n(单)+谓语动词(单培圆弯)可知，D是腔猜错误用法。所以结合分析，应选B。

Every means __has been_______tried but without any result.

选桐启梁 B  has been 

每个方法都局运试旁笑过了，就是没有任何成效。

Answer 4

has been，讲得是名词里的单复同形问题
