美国独立后，工业发展速度加快，特别是资源密集型工业。19世纪中叶开挖了连接伊利湖与安大略湖间的人工运河，并且开通了匹兹堡与苏必利尔湖间的铁路运输，东北部工业区崛起。该图为美国东北部区域图。完成问题。
小题1:19世纪中叶前，匹兹堡主要工业部门及主导区位因素组合，最有可能的是
A．汽车工业----科技发达
B．煤炭工业----煤炭资源丰富
C．钢铁工业----煤铁资源丰富
D．机械工业----市场需求量大小题2:第二次世界大战后，该区域缩小钢铁工业生产规模的原因不可能是
A．区域产业升级

小题2:D
本题考查世界著名的区域发展。
小题1:材料中显示19世纪中叶前，匹兹堡市对外交通还不便利，五大湖西部的铁矿石还不能大量运到此处，而图中显示该地煤炭资源丰富，则当时该地主要工业部门可能是依托煤炭资源的煤炭工业；
小题2:钢铁工业不是劳动力密集型工业，其规模变化与劳动力缺乏关联度不大。
Shaking It Off  One day, a farmer’s donkey fell into a dry well(井). The poor animal cried for hours before his finally found him. The farmer tried hard to pull him out from the well but failed. He felt for the donkey but after carefully thinking about the situation, he that he would save neither the donkey nor the well.
