Square up everything whatsoever that is has been necessary to buy 这句话的语法,我搞不懂
主干是怎么的,is 后面为什么又是has been necessary to buy?
has been necessary to buy什么时态,为什么现在完成时的被动语态又不像?

Square up everything whatsoever that is has been necessary to buy 这句话的语法,我搞不懂主干是怎么的,is 后面为什么又是has been necessary to buy?has been necessary to buy什么时态,为什么现在完成时的被动语态又不
这是一个祈使句,Square up是动词短语,后面的部分是一个宾语从句,everything 是宾语从句主语,whatsoever that is 是everything的定语从句.has been necessary to buy是主+系+表结构的现在完成时态,翻译成该买的就买,一次付清帐.
祝好!问好!

呀。。这不是现在完成时的被动语态,就是一个现在完成时

necessary是形容词词性,Square up everything 是主语,whatsoever that is 相当于是谓语成分,has been necessary to buy 则是宾语成分。或者有可能是同位语补充说明that is 是什么东西
