②英句解析
The old library building on Chestnut Street,which has been vacant for over a year now,was supposed to be made into a community center to serve the senior citizens as well as the younger people of Riverdale.栗树街上的老图书馆已经空了一年多，原计划改成一座社区交谊中心，为里弗代尔的老年人和年轻人服务。
句子主干：【The old library building /老图书馆，主语】【was supposed /谓语，用了一般过去时和被动语态】【to be made into a community center/改成一座社区交谊中心，是动词不定式短语做"was supposed"的状语】老图书馆原计划改成一座社区交谊中心。
划分句子成分：The old library building 〖on Chestnut Street／栗树街上的，是介词短语做后置定语，修饰"The old library building"〗〖which has been vacant for over a year now/老图书馆已经空了一年多，是定语从句做后置定语，修饰“The old library building”。在此从句中，which指代“The old library building”，为此从句中的主语，注意：这个从句的句型为主系表哈〗was supposed to be made into a community center〖 to serve the senior citizens as well as the younger people of Riverdale／为里弗代尔的老年人和年轻人服务的，动词不定式短语做后置定语，修饰"a community center"〗
