1、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 includeds 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.

E are expected to be making an offer to buy First Interstate Bank until they sign a merger agreement including a provision for penalties if the deal were.

答案是A，我的疑惑是IF从句用了虚拟语气，主句不是也应该用虚拟语气SHOULD/WOULD+动词原形么？

2、Several financial officers of the company spoke on condition that they not be named in the press reports.

A that they not be named

B that their names will not be used

C that their names are not used

D of not having their names

E of not naming them

答案A， 为什么会用BE原形呢。我觉得B或者C语法更正确啊。除了在情态动词和TO后面用BE原形还有哪些情况能用到BE原形啊。

以上两题请各位大牛赐教。感激不尽
