62. 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 dumpB. 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答案：D 我的困惑是A。我感觉A才是对的 OG的解释是：Since the dumping continues into the present, the past perfect verb "had benn allowed" should instead be the present "are allowed" 我认为： 1、既然是continues into the present,那更应该用一个完成时态才对。 2、时态修饰的应该是allow，而不是dump。时态应该根据allow来调整才对啊。 3、agreement降低的排放量应该是agreement达成以前所允许的，而不是”现在"允许的排放量。如果选D，那就是 agreement在过去降低了现在允许的排放量，逻辑错误啊。 期待牛人解答 答案：D 我的困惑是A。我感觉A才是对的 OG的解释是：Since the dumping continues into the present, the past perfect verb "had benn allowed" should instead be the present "are allowed" 我认为： 1、既然是continues into the present,那更应该用一个完成时态才对。 2、时态修饰的应该是allow，而不是dump。时态应该根据allow来调整才对啊。 3、agreement降低的排放量应该是agreement达成以前所允许的，而不是”现在"允许的排放量。如果选D，那就是 agreement在过去降低了现在允许的排放量，逻辑错误啊。 期待牛人解答
