2012年6月听力长对话
长对话第一篇：
The dolphins were supposed to press the left-hand lever followed by the right-hand one.
followed by the right-hand one在句子中充当什么成分??后置定语么？为什么要用 followed，ed形式？？
长对话第二篇：
One of the things visitor notices about Harrogate is the large area of open parkland right down into the middle of the town.
能否解释一下right down into 的语法结构？
