77. A1972 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 Verb form; Idiom An agreement that occurred in 1972 is correctly described with the past tense verb reduced. Since The dumping continued after the date of the agreement, the past perfect verb had been allowed should insteadbe the present are allowed (if the agreement remained in effectwhen the sentence waswritten) or the past were allowed ^.f the agreementwas no longer in effectwhen the sentence was written). Since were allowed doesnot appear in any of the options,we can assume that the correct verb tense is are allowed. The phrase amount ofphosphates is clear and idiomatically correct, whereas phosphate amount is not idiomatic. The correct answer is D. 解析里面说，are allowed这里的时态要么是过去时要么是一般现在，为什么不能是现在完成时：reduced 是过去的时间，从签订了aggrement开始以后到现在一直have been allowed?
