(A)    will    begin    at    9    a.m.    and    continue    until    the    supply    lasts

(E)    will    begin    at    9    a.m.    and    continue    as    long    as    the    supply    lasts
我选了b，答案是e

我的理解：
B错因为：1 改变了原有的意思：原来是表示将在9点开始


                                                                 2用until不对，造成句子歧义，as    long    as    好，清楚

cicilla

continue不能用进行时态，用进行时态必然错。

不是NN，和大家讨论！这道题应该也考察了动词分词的用法。

SVO，doing sth。doing表伴随，伴随结果或者伴随动作。本题中continue and begin是平行的，用分词伴随逻辑上不合理。

我选择E，呵呵！if a significant number of these debts will be repudiated,  the solvency of some of the world’s largest multinational banks is at stake.

d为何不行

因为AB涉及到逻辑主语的问题，答案只能在CDE中进行选择。CDE的区别在于：

1、时态上的不同；2、miracle单复数不同；3、连词although, even if区别

从区别2看，E错，从剩下的第1点来看，D不正确，时态上应该是would have found。其实对于3的区别，我也有点疑惑，就不说了！嗬嗬！
