2.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
(E) reduces the amount of phosphates allowed for dumping by municipalities

    答案是A,没问题.
    问题是: B,C中the phosphate amount 和the amount of phosphates差异在那里呢??为什么the phosphate amount不好呢???

    其次E中如果将for dumping改为to dump是否可以接受呢?? 就是说into the Great Lakes 优先修饰municipalities，但是是否可以理解为跳跃修饰???

谢谢solome的解答, 你能将the phosphate amount 这种修饰是不清晰归类??

     归结为一种错误, 应该是什么呢??

我昨天晚上回去琢磨了,可能是这样,不知道对不对:

       要表示A的B的时候，不能直接用名词A+名词B表达， 应该是 B 介词 A

       就是说英语表示“的”， 不能名词连用

       比如这里：the phosphate amount 意思上是说磷的量，就该表达为the amount of phosphates

        再比如the population change就不行，应该是the change in population

       SOLOME还能找到类似的例子吗？？能否验证一下我的解释对不对？？

极度感谢g4yLee，很有道理

     其实我也有疑虑，名词修饰名词多的就是，所以想求证，到底在什么情

     况下名词修饰名词可行，什么时候不可行？？SOLOME能解答吗？？YZYINYIN怎么看？？
