请教两道题:GWD7-Q26,GWD7-Q40

GWD7-Q26:

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

答案给的是E,我选了A,有only if 不是要用虚拟式吗?不明白...\

GWD7-Q40:

Since February, the Federal Reserve has raised its short-term interest rate target five times, and because of the economy’s continued strength, analysts have been predicting for weeks that the target will be raised again in November.

1. because of the economy’s continued strength, analysts have been predicting for weeks that the target will

2. with the economy’s strength continuing, analysts predicted for weeks that the target

3. because the economy continues strong, analysts predicted for weeks that the target would

4. due to the economy’s continued strength, analysts have been predicting for weeks that the target

5. due to the fact of the economy’s continued strength, analysts predicted for weeks that the target will

答案是A,我选了D,后来baidu了一番发现也有人说正确答案是D的,因为要省略would orz

彻底迷糊中,请各位告诉偶一下,究竟是怎么回事 谢谢

40题：

due to表示造成的原因，结果不得不如何如何

since ...决定后面用完成时

D的target后面缺would

40题：

A，because of表达不如because简洁，analyst后面的时态不佳

B，with修饰作用和analysts不匹配 continue一般不用进行时，或者分词形式

C is the best

D，due to表示原因不如because，analyst后面时态不佳

E，due to表示原因不如because，will与前面predicted不匹配

OG里面有两题是predict，后面都是that引导从句，并用will

注意这里前面时predicted，所以后面用了would

26题：

A、B，but only if表达意义不确切

C、D，if从句时态不正确

E is the best，will .. only if do

结构：X will happen if Y happens，注意两者要时态统一，要么都是现在时态，要么都是过去时态。

本段话的时态处理很有意思：一共出现了四种时态，过去完成时，一般过去时，一般将来时，一般现在时。

26.Only if 本来就是连词，无需再加but, 排除A,B

D用的是过去进行，没有道理，不选，剩下C.E, C用的是被动，E是主动，当然主动优先啦。

only if表示条件，不需用虚拟。

40题答案是A吗，我这儿的答案是C啊，楼主用的是哪版啊？？

我认为40题是选D.

1.and后面的句子应该与前句平行,所以时态必须是完成时;

2.predict从句虚拟语态,后面应该接would并省略.

不知道这样分析对不对.

due to只能作表语  sth. is due to some reason

印象中 due to放在句首的从来都不是正确答案
