(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
B This version uses the passive construction in theconditional clause onlyif the output … is trimmed. This use of the passive voice makes this sentence vague; it is now unclearwho needs to trim the output of non-OPEC nations. Finally, the addition of but before only isredundant. 不明白的是这个被动语态下,哪里语义不清晰了。“it is now unclear who needs to trim the output of non-OPEC nations”这个who是指这些国家吗?
