217.
   (30418-!-item-!-188;#058&005391)     (T-3-Q17. ��ɽ-7-14)

Not one of the potential investors is expected to make an offer to buy First Interstate Bank until a merger agreement is signed that includes a provision for penalties if the deal were not to be concluded.

A. is expected to make an offer to buy First Interstate Bank until a merger agreement is signed that includes a provision for penalties if the deal were

B. is expected to make an offer for buying First Interstate Bank until they sign a merger agreement including a provision for penalties if the deal was

C. is expected to make an offer to buy First Interstate Bank until a merger agreement be signed by them with a provision for penalties if the deal were

D. are expected to make an offer for buying First Interstate Bank until it signs a merger agreement with a provision for penalties included if the deal was

最后基本能够锁定在AC之间，但是不明白A怎么被排除的？ 为什么C里用了原型be？

网上的解释是expect  to 后边连接原型，以便平行。

原文：

"Not one of the potential investors" is singular, so "is" must be used rather than "are". So D & E are out.

When using "if" in this case, were must be used always (for example "if I were....", "If you were...", "If he were... , "If it were"). So B is out.

Finally, in "is expected" is subjunctive, so it hould use the verb infinitive. In this case should be "is expected to make .... until .... be ....". (make and be parallel). So C is the choice. (A uses "make" and "is").

但仍旧怀疑。

not one=none 可以查Longman有的

1.主谓一致 得到A B C

2.根据逻辑意思 agreement是两方来签订的 这个句子的意思也是investors与Bank来签的 那么B肯定不对了 因为they指代investors 同样C中的they的指代

3.C就像楼主说的be毫无道理

选A

wenping0530

我会选择C

明显的a provision是一个条件，所以应该用with.

不好意思，看错了，答案就是A

A. is expected to make an offer to buy First Interstate Bank until a merger agreement is signed that includes a provision for penalties if the deal were

A中的THAT是修饰谁的？还是跟哪个搭配啊？

that就是修饰agreement
