(32分)阅读下列材料,回答问题:

材料一 由于中国人闭关自守、骄傲自满,三次灾难性的战争使他们受到了巨大的刺激:第一次是1840—1842年同英国的战争,第二次是1856—1860年同英、法的战争,第三次是1895年同日本的战争。在这些战争中所遭到的耻辱性失败,迫使中国人打开大门,结束他们对西方的屈尊态度,重新评价自己的传统文明。

——斯塔夫里阿诺斯《全球通史》

材料二 李鸿章认为:“吾中国之政教文物风俗,无一不优越他国,所不及者,惟枪耳,炮耳,铁路耳,机器耳。吾但学此,而洋务之战事毕矣。”“中国欲自强,则莫如学习外国利器。欲学外国利器,则莫如觅制器之器,师其法而不必尽用其人。欲觅制器之器与制器之人则或专设一科取士。”  

——《筹办夷务始末·同治朝》

材料三 该国(日本)近年改变旧制,……其变衣冠,易正朔,每为识者所讥。然如改习西洋兵法,仿造铁路火车,添置电报,开煤矿,自铸洋钱,于国计民生不无利益。并多派学生赴西国学习器艺,多借洋债,与英人暗结党援,其势日张,其志不小,故敢称雄东土,藐视中国,有窥犯台湾之举。

——1874年12月10日李鸿章奏折

材料四 从中 * * 党执政的第一天起,应该说就担负起100多年来受到严重阻碍的工业化重任。但是从1953年我国完成战后的经济恢复,转入大规模经济建设以后,资本(包括人力资本)和资源严重缺乏就开始困扰着中 * * 党。

Justin’s bedroom was so full of flat bicycle tires, bent tennis rackets, deflated(瘪掉的)basketballs, and games with missing pieces that you could barely get in the door. His parents pleaded with him to clean out his room.

“What use is a fish tank with a hole in the bottom?” his father asked. But Justin simply smiled and repeated his motto, “Never throw anything out, you never know when it might come in handy.”

When Justin was away from home, he always carried his blue backpack--a smaller version of his bedroom--a place to store the many objects that he collected. It was so worn and stretched that it hardly resembled a backpack anymore.

Justin had earned a reputation for figuring things out and getting people out of otherwise hopeless situations. Many of his classmates and neighbors sought him out when they needed help with a problem. On the first day of school, his friend Kenny, came looking for Justin.

“Do you think you have something in your bag that could help me remember my locker combination?” he asked. “I lost the piece of paper it was written on. I have a science class in two minutes and if I’m late on the first day it’ll make me look bad for the rest of the year.” Kenny looked really worried.

“Relax,” Justin said, taking his backpack off and unzipping the top. “Remember how you borrowed my notebook in homeroom to write the combination down? Well, I know how we can recover what you wrote.”

He took the notebook and a soft lead pencil out of his bag. The page that Kenny had written on had left faint marks on another page in the notebook. Justin held the pencil on its side and rubbed it lightly over the marks. Slowly but surely the numbers of the locker combination appeared in white, set off by the gray pencil rubbings.

“That’s amazing!” Kenny said. “I owe you one.” And he dashed off to open his locker.

It was just another day in the life of the boy whose motto was “Never throw anything out, you never know when it might come in handy.”
