问题 A 1972 agreement between Canada and the United States reduced the amount of phosphates that municipalities had been allowed to dump into the Great Lake.

选项 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

答案 A

解析 B、C中phosphate amount的用法不对。B中的had been doing的时态与句意不符。D中,从句中的一般现在时与主句的过去时不一致。C、E中,reduces与A 1972 agreement所暗示的时间状语不一致,且E中的allow for意为“考虑到”,改变句意。
