【误以为正确】这道题可真是时态中的极品考题啊!首先把BC选项给排除,phosphate amount 不是规范表达,表示数量的词后面的of不能省略;其次,从句意来理解,1972年这个agreement发布,生效,那就只能对这个时间点之后的事情发生作用,不能对过去发生的事情起作用,雇用现在时
had been不对,因为dump的行为持续到了agreement之后,所以不可能是过去的过去,只能是现在时或过去时
两点:1.要减少的是 phosphates ,而不是 phosphates 的量; 2.要减少的是将来的量,不是过去已经倾倒的量,过去既成事实这个无法改变; 举例: (A) In 2010, I decided to reduce the number of calories that I had eaten. (prior to 2010??? How can I retroactively do this?) 2010年的时候我决定去减少我之前吃进去的卡路里的量...已经吃进去怎么减,难道。。 (D) In 2010, I decided to reduce the number of calories that I ate/eat (from that point forward)
应该是are allowed
Since the dumping continued after the date of the agreement, the past perfect verb had been allowed should instead be the present are allowed (if the agreement remained in effect when the sentence was written) or the past were allowed (if the agreement was no longer in effect when the sentence was written). Since were allowed does not appear in any of the options, we can assume that the correct verb tense is are allowed.
过去完成时的表达不符合逻辑 1972年的合约不能减少1970年前排放到五大湖里的量
减少只能是减少以后的量,不能减少以前的量,所以不能用had p.p
A:订立【法规条文】,所修改的东西一定是【从订立起始点,以后生效的东西】所以had beend 是个错误时态; 1972年的法律不能减少市民在那之前 被允许倾倒的垃圾的量 ;也就是说法规的内容的时态 或者和订立是相同,或者比订立时晚
法律法规规定的事情应该用一般现在时,选D
要减少的是将来的量,不是过去已经倾倒的量,过去既成事实这个无法改变。reduce说的是从那以后,所以had been错。
reduce说的是从那以后,所以had been错
为什么说决策类的一般从句用现在时而不用过去完成时呢,我觉得是因为: 你的决策不能改变过去已发生乐的事件,但是可以改变从那一刻开始往后的。
纠结A,D。要减少的是将来的量,不是过去已经倾倒的量,过去既成事实这个无法改变; 举例: (A) In 2010, I decided to reduce the number of calories that I had eaten. (prior to 2010??? How can I retroactively do this?) 2010年的时候我决定去减少我之前吃进去的卡路里的量...已经吃进去怎么减,难道。。 (D) In 2010, I decided to reduce the number of calories that I ate/eat (from that point forward)【时态】
