Workers aren't allowed to go into a big underground computer center until they step up to a machine that takes a quick picture of the tiny blood vessels (血管) inside their eyes.

    Already, a Japanese company has fixed ways that recognize (识别) people's fingerprints in 360 new homes.The machines open the doors only for the 5of the houses.The new security ways are selling well because thieves and robbers are getting better at breaking into buildings and computers that are 6 by keys and locks.Since nobody can steal or copy a fingerprint, or one's eyes, the new machines are 7.

阅读材料，完成下列要求。

材料一：从19世纪60年代末期到90年代初，历时20多年，在中国出现的近代商办企业，可说是小农经济与家庭手工业经济汪洋大海中若干小岛。当这些初生企业的产品出现于市场的时候，外国侵略势力不惜采取降价倾销的办法予以打击。中国企业所需的原料也受到外国洋行抢购的威胁。在中日甲午战争以前，商办企业始终没有取得清政府的正式承认，在设厂、经营和产品销售方面，没有任何的法律保障，完全听任地方官吏随意处置摆布。而许多地方官吏，还对商界企业横征暴敛、敲诈勒索，大大加重了这些企业的负担。

材料二：20世纪初，张謇曾对实业作过这样的解释；“实业者，西人赅（包括）农工商之名。”并认为：“以棉铁为主要，以类于棉之稻麦，类于铁之煤为从要，其它如水利、如电、如铁路、如汽车为次要。”郑观应认为，中国商务之所以不能振兴，其原因“上在官而下在商。官不能护商，而仅能病商”，并提出了革除这一弊政的具体办法：一是设立商部，二是“重订税则，厘正捐章”；三是设商学；四是设立商务所；五是委任熟悉商务的大臣主持商政。
