a 1972 agreement between canada and the united states reduced the amount of phosphates that municiplities had been allowd to dump into the great lake A. reduced the amount of phosphates that municipaliteies had been allowed to dump D.reduced the amount of phosophates that municipalities are allowed to dump
请问为什么不选A? HAD BEEN ALLOWED这里为什么错呀 我理解是 过去在1972年前一直到1972BEEN ALLOWED的 为什么非要用ARE呢
时态问题。Reduced过去式修饰1972年发生的事儿,amount of phos是正确的。可以排除BCE. 重点在于区别 had been allowed 和 are allowed。 如果要用had been allowed的话,是在说这个条约减少了(在订立之前)的倾倒量。试问过去允许的倾倒量怎么可以在1972年,通过协议的方式减少呢?协议影响的应该只是订立生效之后的倾倒量。 确定了这一点之后,我们可以看到还有两个选择are allowed (说这句话的现在依然生效)和were allowed(说这句话的时候已经失效了)。但是选项中没有这一项选择。

Ron的解释:
That's the difference between A (wrong) and D (correct), so I can't really ...
我也很纠结这道题,同样错选了A,对于yanbin700说的也表示有一定的赞同,但提供一下另一个角度的考量,即便是allow这件事情,是不是本身也是具有持续性的呢?过去完成时表示一个动作/事情发生在过去,并持续到过去的某个时间为止,这里allow to dump这件事情也并没有因为这个agreement就停止,所以用过去完成时也并不合适?
继续续上文:
Ron的解释:
That's the difference between A (wrong) and D (correct), so I can't really write another sentence other than A & D. Here's a parallel example which might help to shed some light on the issue:
(A) In 2010, I decided to reduce the number of calories that I [size=14.0084px]had eaten. (prior to 2010??? How can I retroactively do this?)
(D) In 2010, I decided to reduce the number of calories that I [size=14.0084px]ate. (from that point forward)
结果被之后的一个学生[size=14.007px]challenge:
i don't have problem with actual D) but i think what you wrote is not similar to actual D) because your sentence somehow implies that you [size=14.0084px]stopped taking in reduced no. of calories. In fact, following sentence would be similar [size=14.0084px]"In 2010, I decided to reduce the number of calories that IEAT" as it shows you still take reduced no. of calories. This is similar to "are allowed" in actual D).[size=14.0084px]Do you think i am correct
Now onto actual A), it says "had been allowed" not "had been dumped". If A) said that [size=14.0084px]"agreement reduced the amount that had been DUMPED by municipalities" then i agree that it is wrong because amount dumped before agreement came into effect cannot be reduced. But, A) says "had been allowed" so doesn't it mean that whatever was allowed earlier changed after the agreement.[size=14.0084px]E.g. before 1972, municipalities had been allowed to dump 10 tonnes per day but after 1972 municipalities were allowed to dump 8 tonnes per day.
