分析这句话的时态问题
At least sorting out the things she should【have】 discarded years ago was now being made easier for her
1、其中的have为什么不是had,这里应该表示过去就应该被完成了的.
2、如果说情态动词should后加动词原形,所以had就变成have了,即should have.那这样又怎么能够看出它到底是现在完成时 还是过去完成时呢

|采纳率95.2%你首先得断句 sorting out the things 是主语 was 是谓语
去掉being made语法和意思也正确
但本句实际上是make sth easy 词组的被动 sth be made easy
又因为是进行时有了was 这个be动词 后面动词要加ing 所以是 sth was being made easy1年前查看全部

|采纳率88.2%如果你有那个银行的支票,支票底下有一长串号码,基本上分两部分,后面一组是你的账户号码,前面就是routing number,那是用来确定你的银行所在城市等信息.当然最简单的方法,直接打电话去问.
Routing number和Swift Code不一样.Swift Code用来确定各家不同的银行集团,用于国际间的汇款.Routing number似乎美国专用的,不仅用来确定银行,并且确定处理该业务的具体分行所在的城市.1年前查看全部
