The Organization of Petroleum Exporting Countries (OPEC) had long been expected to announce a reduction in output to bolster sagging oil prices, but officials of the organization just recently announced that the group willpare daily production by 1.5 million barrels by the beginning of next year, but only if non-OPEC nations, including Norway, Mexico, and Russia, were to trim output by a total of 500,000 barrels a day.

A.year, but only if non-OPEC nations, including Norway, Mexico

, and Russia, were to trim output

B.year, but only if the output of non-OPEC nations, which includes Norway, Mexico

, and Russia, is trimmed

C.year only if the output of non-OPEC nations, including Norway, Mexico

, and Russia, would be trimmed

D.year only if non-OPEC nations, which includes Norway, Mexico

, and Russia, were trimming output

E.year only if non-OPEC nations, including Norway, Mexico

, and Russia, trim output

这道题选E没有问题，我的问题在没有划线的部分（红色字体），为什么不是would而是will呢？谓语明明是过去式...

求指点

因为pare发生在“写这个句子时”的将来。如果是would的话，就说明写这个句子的时候已经发生过了。
