两道score800的语法题~十分纠结~~版主现身吧~真不懂了

If the industrial concern had not made the monthly payment, the credit bureau would have downgraded its credit rating.

A. had not made the monthly payment, the credit bureau would have
B. had not made the monthly payment, the credit bureau had
C. should not have made the monthly payment, the credit bureau would have
D. did not make the monthly payment, the credit bureau would have
E. is not making the monthly payment, the credit bureau will have

answer:A  可是D哪错了，没有条件句必须过完时态的说法吧？

The International Space Station recently received two new solar panels, the largest solar arrays ever constructed, which would be increasing the space station’s power fivefold, and are essential to further station science experiments and will reflect enough light back to Earth to make the space station one of the brightest objects in the night sky.

A. which would be increasing the space station’s power fivefold, and are essential to further science experiments and will reflect enough light back to Earth
B. which will increase the space station’s power fivefold, are essential to further science experiments, and will reflect enough light back to Earth
C. so that the space station’s power is increasing fivefold and this is essential to further science experiments and then they will reflect enough light back to Earth
D. scientists say will increase the space station’s power fivefold and will be essential to further science experiments, and it will happen that they reflect enough light back to Earth
E. causing there to be a fivefold increase in power at the space station, and more science experiments, and also causing enough light to be reflected back to Earth

answer:B  这个就更无语了，感觉哪个都不对，句子结构就都有问题啊？B的are不成run-on了？

再补充一题，真是变态啊~~
Buildscape users can now better manage materials with real-time access to pricing, purchasing and inventory information 24 hours a day, 7 days a week from any location, whether rooftop building site with a strong clear signal or underground parking site with no signal at all.

A. whether rooftop building site with a strong clear signal or underground parking site with no signal at all
B. whether a rooftop building site with a strong clear signal or an underground parking site with not any signal at all
C. be that location would be from a rooftop building site with a strong clear signal or from an underground parking site with no signal at all
D. be it a rooftop building site with a strong clear wireless signal or an underground parking garage with no signal at all
E. be them rooftop building sites with strong clear wireless signals or underground parking garages with no signals at all

正确答案：D   这用法真没见过......

加问一下，表对过去的虚拟必须是,if had done ,  would have done？？没有did的形式？？？

咋看都不是800分的题!都是基础题! 第一道题目就一个虚拟语气,if had done ,  would have done ,这是高中就学过的语法知识! 一个点就排除全部! 第二道就是考了一个平行结构!逗号是可以加的! 最后一个不懂!

uh...第一题我觉得应该是A...虚拟语气针对过去情况的话，主句应该是would have done，虚拟条件句要用had+过去分词。

第二题时态没有问题，用一般过去时、一般现在时、一般将来时都没有问题，但是就是不能用A里面的would be increasing，将来进行时awkward，且逻辑上increase和reflect的时态应该一致。
increase用了一般将来时 will increase 表示了现在仅是received，还没有构建好，还没有发挥increase的功效。
其他几个选项都有大错。

第三题，略微倾向于A，不觉得A里面的whether用法有误。
见下例：
Shipwrecks are more likely to be found undisturbed at great depthsthan in shallow coastal waters, where archaeological remains are exposed to turbulence and are accessible to anyone in scuba gear, whether archaeologist, treasure hunter, or sport diver.

be it的用法比较老了，是whether it be的倒装式，whether it be用了subjunctive form不知道GMAT里面接受与否，whether在GMAT里面出现甚多，但从未出现过用whether it be，而都是用了whether it is的，所以be it的用法，GMAT接受与否仍然是个悬念。
补充语法大全中的一题：
134. As rare as something becomes, be it a baseball card or a musical recording or a postage stamp, the more avidly it is sought by collectors.
(A) As rare as something becomes, be it
(B) As rare as something becomes, whether it is
(C) As something becomes rarer and rarer, like
(D) The rarer something becomes, like  
(E) The rarer something becomes, whether it is
key: E
由此，我想难道是因为A选项列举的内容不如D清晰所致？这绝非GMAT题的考法……
或许whether的用法仍需高人提点一二。

对于第一题，OG12-67中有解释，

Conditional constructions require specific verb
tenses. For a past condition, the subordinate
clause introduced by if uses the past indicative,
and the main clause uses the conditional if x
happened, theny would happen.

主句应该领先从句一个时态

第一题，答案给的是A，搞错~不过还是不懂
第二题 忽然明白了，一直以为are essential to further science 是去修饰主句的，但现在看来应该是都属于which从句，三个并列修饰 largest solar arrays 的，还是没注意意思啊~ 可是这个时态....

第三题 形式很怪哎~~~怎么读也感觉不爽，为什么非要这么说呢？AB用whether也没问题吧？

第一题我选D

第二题如果非要说B的话我觉得唯一能解释通的就是are 前面的which省略了

第三题选 D
I like flower, be it yellow or red.见过类似用法,

？？？不懂.....再来人啊，版主现身说说吧~~~~

crazyxxx

第一题貌似解释不同吧
if过去虚拟, 主句过去完成时,想表达什么?
貌似B不对吧.
