被吹到的那棵树已经被移走了,表示树被吹倒是过去发生的动作,A表示正在进行,显然不可以选,而B既可以表被动又可以表示过去发生的动作,所以选B

过去分词短语做trees的定语 本身已又被动的意义,不必加being

分词作定语,那些在风暴中被吹倒的树。被吹倒,所以用blown down.
你选的being blown down,虽然也是被动,但含一个“正在…”的含义,这里与语境不符。

D 表示将怎么样,表示将来,所以不选
A 是正在被刮倒,说话的当时树显然已经倒了,不是正在倒.
B是表示已经倒下的树

being done 强调的是“正在进行的被动状态”,过去,现在,将来,都可以用,比如At this time tommorrow ,my car will be being repaired.
而 blown down 更强调的是“被动”
