OG12 74请教

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.

我觉得标红句说得十分清晰，Ron举的例子完全是在偷换概念。“之前允许吃的萝卜数”和“之前吃的萝卜数”完全是两个概念。对此，Ron没有进一步解释。而之后的Tim，也被这个学生反复打脸。


所以我真心认为哈，别纠结这道题了。这道题选A肯定是优于D的。

A错误的原因是过去完成时表示一个动作发生在过去的另一个动作之前。所以这里的意思是allow在reduce之前已经完成了，明显是不符合逻辑。

嗯，我最后也是这么理解的。毕竟OG的正确答案是不会错误的。

可以用[法规规定的都是客观事实，所以要用一般现在时]，这个说法排除d吗?

这题可把我纠结死了 我还是想不明白...  另外一点我也想问 为什么不能用reduces，1972年的合约在现在也是生效的啊，怎么能通过1972就排除一般现在时

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？

我第一次做，凭语感，选择的是D。看到一个版本的答案是A，觉得很奇怪

正如前面有人从OG 的解释里找出来的。 had/have + 完成时，有种动作完成的感觉。你不能降低过去的已经被允许过的量。因此选择D。
