优质解答

1.There being no cause for alarm(这种结构称为独立主格结构,一般充当状语,there被当作了逻辑主语）
相当于Because there was no cause for alarm
如：
Weather permitting（=If weather permits),I will go out.
There being many students in the classroom,the teacher began his lesson.
2.现在进行时的被动语态：
The flag is being raised now.正在升旗.（旗正在被升上去）
B C rise不及物动词,没有被动
D 及物的.应该用被动
用rising就对了.
