阅读下列材料

  材料一:台湾高山族耕田图

  材料二:徐州古丰县,有村曰朱陈。去县百余里,桑麻青芬氲。机梭声札札,牛驴走纷纭。女汲涧中水,男采山上薪。县远官事少,山深人俗淳。有财不行商,有丁不入军。家家守村业,头白不出门。——白居易《朱陈村》

  材料三:松江旧无暑袜店,暑月间穿毡袜者甚众。(明)万历以来,用尤墩布为单暑袜,极轻美。远方争来购之,故郡治西郊,广开暑袜店百余家。合郡男妇,皆以做袜为生。从店中给筹取值,亦便民新务。——〔明〕范濂《云间据目抄》

  材料四:机器制造创于泰西(西方资本主义国家)而效行于中国……天津麦面盛行,今秋又有宁人(指朱其昂)购来磨面机器一座,在紫竹林招商局下开张磨坊,名曰“贻来牟机器磨坊”。日计焦煤若干,及用机器司务两人外,又需小工十余人,开销似乎过费。然事半功倍,出面极多;且面色纯白,与用牛磨者迥然不相同。——1878年12月14日《申报》
