下面两幅图分别示意不同时期建设的甲、乙两个钢铁基地，两个钢铁基地都符合当时工业布局的原则。据此回答下列小题。

感恩:生命中的心灵之花
①“滴水之恩，涌泉相报”，这是一句并不深奥的话，可是真正理解并做到的人能有多少呢？生活中关于翻脸不认人或以怨报德的“白眼狼”的传说，每每有所耳闻，令人徒然唏嘘不已。于是，说某某人“不知好歹”、“良心被狗吃了”的斥责与评论，就在口头传播中无形地为某人画了像，其人品足以让他失去亲友的关爱与尊重，让他的事业和生活面临很多困难。
②现在谈论感恩这个话题，具有相当广泛的社会意义。一方面，不少成年人被“金钱万能”所左右，自私自利，只认钱不认人，只讲索取不讲回报，淳朴之风、感恩之心日渐式微；另一方面，独生子女过分受宠，衣来伸手、饭来张口，不知体贴和心疼父母，虽然能背诵“谁知盘中餐，粒粒皆辛苦”、“慈母手中线，游子身上衣”这样的古诗，可是自我中心意识在家人的不断纵容中强化。因此，感恩教育要将学校教育、社会教育、家庭教育结合起来，决不是仅仅靠书本知识就能奏效的。在价值多元化的状况下，如何弘扬感恩美德，培育青少年感恩的人格并自觉形成感恩的伦理观，这是构建和谐社会的深层次内容之一。  
③感恩不是浅层次的庸俗的“投桃报李”，更不是表面的甜言蜜语。它是人类在生命延续过程中的心灵之花，散发出沁人心脾的芳香；它是人性中真善美的乐章，将爱心传递，使人的理智与情感本身具有了审美的意义；它是为人父母者的幸福与欣慰，是为人子女者的本分与情操，是人与人之间的虔诚。假如没有感恩，人类的繁衍与生存就成为纯粹生物学意义上的基因复制，陷入鸡生蛋、蛋生鸡的简单怪圈。这样，就诞生不了朱自清的美文《背影》，就品味不了朱德感人肺腑的《母亲的回忆》，也欣赏不了童话般的校园歌曲《外婆的澎湖湾》。
④由此看来，感恩实在是不用勉强的，它是我们人生的必修课，更是一个高尚的人应该具有的境界与素质。
⑤父母养育子女，并非“施恩图报”，父爱母爱如山高比海深。那么，子女对父母的感恩就是绿叶对根的情意，孝敬在言行上，也在心灵深处。有智者说，看一个人品行如何首先就看他是否孝敬父母，一个人如果连父母都不孝敬，那就既不能做朋友，也不能扛重任。诚哉斯言！
⑥感恩，就是孝敬父母，就是怀念恩师，就是报效祖国，就是对于成长的一种回馈。感恩，将使我们的心灵永远温暖如春 。

     “When I grow up, I want to be...”

        Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school.

        However, it seems career options aren't only based on personal taste. In a survey carried out by teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the U．K. in May 2011 by job website monster.co.uk, in which medicine was the top choice among U．K. teenagers aged between 13 and 17.

        Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high­profile professions is often seen as a sign of upward social mobility.

        It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the U．K. tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models “for their wealth”. Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”．

        However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens' survey discovered, a variety of unconventional jobs—coffee shop owner, gourmet (美食家), waiter at a fast food restaurant—are among teenagers' career choices. They can be equally interesting and rewarding jobs.

       With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.
