In order to keep the balance of ecosystem, every possible means _______to deal with the problems of the over-exploiting of natural resources.
A.has tried
B.has been tried
C.have taken
D.have been taken
题型:单选题
难度:中档
来源:不详
答案
B
试题分析:考查主谓一致和语态。Means(方式,方法)是一个单复数同形的名词。本题means前面有every修饰,说明本句中的means是一个单数形式,故谓语部分使用单数形式,排除CD。句意:为了保持生态的平衡,每一种可能的方式都已经被使用了来处理过度使用自然资源的问题。故使用被动语态。B项正确。
点评:Means(方式,方法)是一个单复数同形的名词。Every后面要加单数名词,如every one等;all后面要接复数名词。本题的means前面加了every说明该词在本句中是单数形式,故谓语动词也使用单数形式。
