了不得，BY语法全解例题居然和OG12对着来

leosnoon

亲们注意了，BY太不靠谱了吧，公然和OG12对着来。我还是先看的BY再做的OG，害得我以为这道题错两次，而且第一次居然是选对了的，今天又翻起BY看错题的时候，居然发现他老人家有问题，郁闷ing
下面是白勇语法全解第四章第四小节例题3
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

(D) reduced the amount of phosphates that municipalities are allowed to dump

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

BY 首先就把D否定了，说的是定语从句的一般现在时 are allowed to...与主句的一般过去时reduced sth., 时态不协调。咋一看，还真有理，不过看了OG你就会发现同样是语法，中式思维和西式思维怎么相差那么大叻。。。

下面是OG12对这道原题的解释：
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 instead be the present are allowed (if the agreement remained in eff ect when the sentence was written) or the past were allowed (if the agreement was no longer in eff ect when the sentence was written). Since were allowed does not appear in any of the options, we can assume that the correct verb tense is are allowed. The phrase amount of phosphates is clear and idiomatically correct, whereas phosphate amount is not idiomatic.

A Had been allowed should be are allowed.

B The phosphate amount should be the amount of phosphates; the omission of some form of allow is incorrect since the agreement changed not the amount dumped, but the amount permitted to be dumped.

C Present tense reduces should be the past tense reduced; the phosphate amount should be the amount of phosphates; have been allowed should be are allowed.

D Correct. Th e past tense reduced is correctly used in this sentence to describe a past
action, and the present tense are allowed is used to describe the present situation.

E Present tense reduces should be the past tense reduced; allowed for dumping is an incorrect idiom; allowed for dumping by municipalities is awkward.

所以啊，不能迷恋题海，要回归OG剑谱，仅以此贴提醒大家做BY时留意。
