以下是引用danni1221在2007/8/21 19:00:00的发言：

我觉得D没错，only if 后面用were表虚拟语气

我认为D的错误在于主谓一致错误。

year only if non-OPEC nations, which includes Norway, Mexico, and Russia, were trimming output

其实不用管那么多，直接看announced that后面的句子就行了，其实就是，if +一般现在时，主语+will ，这道题前后颠倒了一下，所以 A,C,D的时态都不对，而B中的only if 已经表达了转折的含义，就不需要but了，而且include修饰nations，应该用复数

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.

A.    year, but only if non-OPEC nations, including Norway, Mexico, and Russia, were to trim output
錯  were to 結構  (我也不知道怎麼用)

B.    year, but only if the output of non-OPEC nations, which includes Norway, Mexico, and Russia, is trimmed
錯  which includes 在ETS比較喜歡 including 但即使改 including 也錯 因為
     n of n, which which修飾哪一個不一定 同例子在pp8有 忘了哪了 類似  
     有 svo,like()with...,svo都有引起模糊
C.    year only if the output of non-OPEC nations, including Norway, Mexico, and Russia, would be trimmed
錯        IF 現在式,未來式      主動比被動好
D.    year only if non-OPEC nations, which includes Norway, Mexico, and Russia, were trimming output
錯 which錯   if ving錯
E.    year only if non-OPEC nations, including Norway, Mexico, and Russia, trim output
正確答案 including 簡潔 if v, sth will 結構合理  =sth will..., if  現在式

逆水潜龙

关于A，be to do sth在百度上能查到用法啊·不能证明在GMAT中它一定就错吧？
我想最主要都是用主将从现来解，不要轻易相信自己总结出的所谓不合理搭配·

"if x happens, y will happen" is the idiom.

明白了，想起Manhattan里有
If…Then constructions

(1) General Rule with no uncertainty

eg: IF Sophie EATS pizza, THEN she BECOMES ill.

IF Present, THEN Present.

=WHENEVER Sophie EATS pizza, she BECOMES ill

(2) General Rule with some uncertainty

eg: IF Sophie EATS pizza, THEN she MAY BECOME ill.

IF Present, THEN Can or May.

(3) Particular Case (in the future) with no uncertainty

eg: IF Sophie EATS pizza tomorrow, THEN she WILL BECOME ill.

IF Present, THEN Future.

=If Sophie HAS EATEN pizza, then she WILL BECOME ill.

(4) Unlikely Case (in the future)

eg: IF Sophie ATE pizza tomorrow, THEN she WOULD BECOME ill.

IF Hypothetical Subjunctive, THEN Conditional (would/could).

Conditional表示对不可能或不真实条件的假设

(5) Case that Never Happened (in the past)

eg: IF Sophie HAD EATEN pizza yesterday, THEN she WOULD HAVE BECOME ill.

IF Past Perfect, THEN Conditional Perfect.

(6)would不会出现在 if部分，should不会出现在 if…(then)句型

我开始一选了would,没有注意到if 从句不能用would 和should,悲催。manhattan都白看了。。。
