我就不明白了,在OG11的基本语法规则里,他们描述现在完成时就说的是Describe an action that began in the past and continues into the present. 但是下面我用红笔标注的地方却明明白白写的是continues into the present! 这个怎么解释啊?我实在想不通! 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(A)>>
(E) reduces the amount of phosphates allowed for dumping by municipalities
该题的答案,ETS认为答案不是A,而是D.
ETS是这么解释的(下面原文照抄):
Verb form + Idiom
An agreement that occurred in 1972 is correctly described with the past tens verb reduced.Since the dumping continues into the present, the past perfect verb had been allowed should instead be the present are allowed.
A Had been allowed should be are allowed.
B The phosphbates amount should be the amount of phosphates;the meaning of the sentence is changed by the omission of any form of allow.
C The 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.The past tense reduced is correctly used in this sentence to describe a past action,and the present tense are allowed is used to describle the present situation.
E The present tense reduces should be the past tense redueced;allowed for dumping is an incorrect idiom;allowed for dumping by municipalities is awkward
The correct answer is D. |
