标题: 大全002 （OG 11 版 62） [打印本页] 作者: kangkangv 时间: 2010-3-31 13:47 标题: 大全002 （OG 11 版 62） A 1972 agreement between Canada and the United Statesreduced 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 这题正确答案是D。 我选的是A。当时认为主从句时态要一致，而选了A。 OG 给出的解释是 由于dumping continues to the present，所以用现在时。但为什么不能认为 dumping 是在 reduced 之前发生的，用过去完成时呢？ 麻烦大家解答一下，谢谢：）作者: slamshady 时间: 2010-3-31 14:21
agreement是政府规定，其内容在被修改之前的任何时侯都是有效的，就像客观真理一样，所以要用现在时。。。这里的dump和reduce没有时间先后关系作者: TeamCancer 时间: 2010-3-31 22:40
这道题在白勇里的答案好像就是A，属于扯淡题，因为题目本身就有二义性
