OG12 74 用语义也不能理解

fanlynx

74.    A 1972 agreement between Canada and the United States reduced the amount of phosphates that
municipalities had been allowed to dump into the
Great Lakes.
(A)    reduced the amount of phosphates that municipalities had been allowed to dump
(B)    reduced the phosphate amount that municipalities had been dumping
(C)    reduces the phosphate amount municipalities have been allowed to dump
(D)    reduced the amount of phosphates that municipalities are allowed to dump
(E)    reduces the amount of phosphates allowed for dumping by municipalities正确答案为D，LZ选的A
从语法上来说A没有问题啊，had been前面有一般过去时
从语义上，LZ是这么理解的
that从句修饰那个amount，那个通过协议减少的amount是协议签订前被允许的amount，也就是过去的过去
所以我觉得A反而更好啊~
那位NN快来指出我哪里想错了啊~~~

水一下。 这题自己也看过几遍了。很能够理解lz的想法啊！！说得不好见谅啊~
XDF 讲义说。“政府法令 具有持续性 应该是得用 一般时态的”

OG解释说，had been allowed 这个时态 说明 过去一段时间 允许 倾倒 磷肥, 现在已经不允许了。
但是，因为倾倒磷肥 这个动作 在协议（agreement）之后任然继续，所以用一般现在时。
og 中解释第二句，Since the dumping continued after the date of the agreement, the past perfect verb HAD BEEN ALLOWED should instead be the present ARE ALLOWED .........

ps: that 似乎应该修饰 phosphates 吧？ that 应该紧跟先行词。

白勇的语法全解上面 答案还是 错误的A 和lz选的一样！
白勇是这么写的
第一步：时间标志 1972 决定了谓语动词reduce 必须使用一般过去时态。排除C、E
“D选项 定语从句的一般现在时 are allowed to ... 与主句的一般过去时态 reduced sth., 时态不协调。 排除 D  这个 说错啦！！
第二步：定语从句就近修饰名词 amount, Municipalities had/have been dumping amount to the Great Lakes. 动作 dump 和动作对象 amount, 逻辑搭配不合理。 排除 B、C。

白勇的答案 和 OG 上的不一致。 应该还是以OG 为准的吧！

先道个歉....发完了贴没有及时回复~~该打该打~一定改掉这个坏习惯
嗯明白了！
我不知道为什么一直觉得that是修饰amount的
大概是钻到死胡同里出不来了然后自己的答案还越想越对。。。。。汗。。。
谢谢！

og解释： Since the dumping continued after the date of the agreement, the past perfect verb bad 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(if the agreement remained in effect when the sentence was written) or the past were allowed (if the agreement was no longer in effect when the sentence was written).

我的理解：定语从句修饰的是pho。。 不是amount of P。即定语从句意思是：被允许倒的P，而非lz所说：之前被允许倒的量。
所以agreement之后还在倒，不能用完成时。
