1.A
remain是不及物动词,没有被动语态.所以不能用它的过去分词去做定语；
固定短语：be determined to do sth,换成状语时,只要去掉be动词即可,表示状态.
2.C
句中的could be heard...,暗示是“正在被打开和关上的桌子”所发出的声音,所以用being opened and cloese来修饰desks,表示动作的正在进行和被动关系；
选A表示“已经被打开/关上的桌子”,当然没有声音了；
B是“即将要被打开/关上的桌子”,当然也不能发出声音.
3.B
用形容词短语做状语,只强调延续的状态,而不是强调正在发生的动作.
4.B
用现在分词做结果状语,表示由主句动作可以顺其自然推理出来的结果.
如果用C,则强调“先造成12000多么旅客延误,然后再堵塞了约1400公里的道路”,这是不符合清理的.
即现在分词的完成式强调分词动作发生在谓语动词所表示动作之前.
