GWD 7-26

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 will pare 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.

1. year, but only if non-OPEC nations, including Norway, Mexico, and Russia, were to trim output
   
2. year, but only if the output of non-OPEC nations, which includes Norway, Mexico, and Russia, is trimmed
   
3. year only if the output of non-OPEC nations, including Norway, Mexico, and Russia, would be trimmed
   

   
   

4. year only if non-OPEC nations, which includes Norway, Mexico, and Russia, were trimming output
   
5. year only if non-OPEC nations, including Norway, Mexico, and Russia, trim output

答案E

C怎么会顺眼呢？only if the output …… would be trimmed by a total of 500,000 barrels a day，trim是修剪降低削减的意思，翻译一下只有当产出每天被500，000桶石油削减……会有这种意思吧

A：前面已经有but表示转折了，还是不要的好；were to trim时态、用法都不够好

B：but；includes要用复数；is trimmed错

C：including短语修饰歧异；被动

D：includes要用复数；were trimming时态inconsistence

E：正确

c.year only if the output of non-OPEC nations, including Norway, Mexico, and Russia, would be trimmed

我觉得是这样的，你可能默认是including修饰的是nations，所以觉得是对的，但是按照og10讨论大家的一致认同和ets的prefer，如果是修饰nations，前面是不用逗号隔开的；这里，including在语法上就会有连个可能的修饰对象前面的of短语的中心词output，还有就是句子的动词would be trimmed，翻译过来的话，逻辑意思就不通了。
