天山7-Q14:

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

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也有选C，我选D，为什么agreement后面用is而不用are，为什么if the deal后面用were而不用was。

a merger agreement 是单数啊，一份兼并协议，当然用单数咯！

if the deal后面用were而不用was应该是表虚拟吧！个人意见　不确定啦～～
