一道关于时态的问题

justabeginning

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。

还是有点不理解诶。。。英语中，通常间接引语都是由用过去时态的动词引导的。这时直接引语中的动词必须变成相应的过去时态。如：
------------------------------
直接引语              间接引语
------------------------------
一般现在时          一般过去时
现在进行时          过去进行时
现在完成时          过去完成时
现在完成进行时  过去完成进行时
一般过去时          过去进行时
一般将来时          条件语气
将来进行时          条件进行时
------------------------------
