红颜色为正确答案,绿颜色为我的答案.本题考虚拟语气.我觉得D优于A.请教!!!!

D不是虚拟。

A是一种比较少见的虚拟句，即虚拟条件句+真实主句，通常GMAT考的是虚拟条件句+虚拟主句。

D错误，因为没有真实条件句+虚拟主句的用法.

我还有个疑惑，就是为什么后面的是倒装呢，一般虚拟的话，should提前，从句倒装，主句就不倒装了

下面是例子

1) Should you be interested (if you are…),I have a book on the subject you might like to see.
2) Should you need any help (=if you need any help), you can always phone me at the office. (LONGMAN)

3) Should one of a pair die, the remaining fish cannot swim off in search of a mate, nor is one likely to arrive.(大全RC)

4)Should the environment ever become too extreme to support human life, naturalists predict that mice would be able to adapt and survive.此句把从句中的条件句前置了。

那为什么这个句子倒装呢

自己的判断顺序:

主谓一致干掉BC, "if+将来时"干掉E, "there is的不简洁+reputation of的awkward&wordy+would be的时态不对称"干掉D.

记得不是很清楚了， 不过高中英语里面好像有讲过， if从句省略if则需要部分倒装

完全同意AVANTASIA的思路

自己的判断顺序:

主谓一致干掉BC, "if+将来时"干掉E, D的问题在于there be，一般在GMAT中，there be +具体名词，所以看到there be +其他乱七八糟的东西，先打一个问号.

另外，对于这题，我也没有看的很懂，但用排除法可以搞定。我想说的是排除时一定确定必错。

BC主谓不一致是必错，

E，if+将来时必错

D的问题在于there be，但吃不准，但A无明显错误，所以我选A

事实上，有时感觉语法提也是一种逻辑的思路

同意rhod的看法，（Ｄ）还原出来就是

the solvency of some of the world's largest multinational banks would be at stake,if there is a repudiation of a significant number of these debts.

条件句用现在时，而主句用过去将来时，这是不符合虚拟语气用法的
