Metals have many good properties,as has been stated before.
as has been stated before.
as怎么理解
为什么用完成时的被动 什么意义

Metals have many good properties,as has been stated before.as has been stated before.as怎么理解为什么用完成时的被动 什么意义
原句意为:金属,就如前面所陈述过的那样,有着许多好的特质
as has been stated before 是个非限制性定语从句.
as 代替整个主句“金属有着许多好的特质”这回事,作主语,谓语是陈述,一看就知道是被动关系;再从 before一关键词就可看出“完成”这一概念,故从句用现在完成时
请及时采纳,不懂继续问( 天天在线 )

他有很多财产,就象原来曾经陈述(证明)的一样。
as在本句意思是就象,正如的意思。
这些财产原来被证明过,是被动语态,原来证明对现在还有影响,所以用完成时的被动语态。
希望能帮到你,祝更上一层楼O(∩_∩)O
