1.so fast__that it is difficult for us to imagine its speed.

so / such...that结构中的so或such位于句首可以构成部分倒装句,表示强调so /such和that之间的部分.
2.__for the leadership of the party.we should not have succeed
A.had not it been
B.had it not been
选择 B
原句应该为If it had not been 这里是省略掉了If之后倒装的句式.也是英语常考题型.
3.__no air or water,there would be no life .
A.were there
B.is there
选择 A
同样是If引导的虚拟句的省略倒装形式,因为是虚拟句所以系动词用了were,原句应该为If there were no air and water省略If之后,were提前,所以选择A
