In November of 1995, Leslie was working for the Department of Social Services in North Carolina. Her job is to take children out of dangerous home situations and place them in foster homes (寄养家庭). During her first such task, Leslie saw that the children she had come to pick up were carrying all of their things in plastic bags. They didn’t have suitcases (手提箱) for their clothes. Wanting to help these children, Leslie asked her mother if she could have the family’s old suitcases to give to them. Leslie’s 10-year-old sister Abby asked how many foster children there were in the area and found out that there were 300. Most of those children had to carry their things from place to place in plastic bags. Leslie’s care and the thought of those 300 children made young Abby take action. Abby decided to ask people to give away their old suitcases to these foster children. She began making and hanging posters, speaking at churches, and asking other children for help. But after a few weeks, she had not received any ones. Abby decided to buy some suitcases with her mother’s help. That’s how Abby Burnside set up her program, Suitcases for Kids. By March of 1996, Suitcases for Kids had collected and sent 175 suitcases to the foster children. Finally, Abby’s efforts were not iced by the media. Her story was in newspapers and magazines and Abby appeared on popular television shows. As the story became known, Abby’s local chapter (分支机构) received more and more suitcases, until it collected 4,000 suitcases in 1996. Soon, Abby was traveling to different states to help set up new Suitcases for Kids chapters. By the end of 1996, there were Suitcases for Kids chapters in 19 different states. After two full years, Suitcases for Kids had set up chapters in all 50 states. By its sixth year, the little organization reached international attention, having chapters in more than ten countries. Now thousands of children around the world can carry their things in suitcases instead of plastic bags just because a 10-year-old girl decided one day that she just wanted to help. 64. Was Leslie’s work to help the foster children? 65. What did the children use to carry their things at first? 66. Why did Abby decide to take action? 67. In which year did each state have Abby’s chapters? 68. What made Abby help the children successfully? Learning to understand your mother well is what you should do. Here are the best tips towards a better relationship with her. They are not necessarily surprising, but they have worked for many people. Try them.
中国古代科学家5位 1、张衡（公元78—139 年），字平子，南阳西鄂人（今河南省南阳市石桥镇夏村），张衡观测记录了两千五百颗恒星，创制了世界上第一架能比较准确地表演天象的漏水转浑天仪，第一架测试地震的仪器——候风地动仪，还制造出了指南车、自动记里鼓车、飞行数里的木鸟等等。张衡共著有科学、哲学、和文学著作三十二篇，其中天文著作有《灵宪》和《灵宪图》等。为了纪念张衡的功绩，人们将月球背面的一环形山命名为“张衡环形山”，将小行星1802命名为“张衡小行星”。郭沫若对张衡的评价是：“如此全面发展之人物，在世界史中亦所罕见，万祀千龄，令人景仰。” 2、沈括（1033－1097），字存中，北宋科学家杭州钱塘人。沈括的科学贡献遍及天文、数学、物理、地质、气象、生物、医学等各领域。梦溪笔谈》全面总结了宋朝以前我国科学技术成就，在世界上享有极高声誉。在数学上，他发明了“隙积术”和“会圆术”，“隙积术”比国外计算高阶等差级数的公式早500 多年，“会圆术”是我国球面三角学的发展奠定了基础。沈括提出的地磁有偏角存在现象，比哥伦布1492年横渡大西洋时“首次”发现磁偏角现象要早400 年。李约瑟教授称沈括是中国整部科学史中最卓越的人物。赞许他的著作《梦溪笔谈》是中国科学史的里程碑。 3、郭守敬（1231——1316）字若思，顺德邢台人。元代天文学家，水利专家。先后制造了简仪、高表、仰仪、正方案等近20种天文仪器，很多仪器其设计的科学性和使用的准确性，在当时世界上也处于领先地位。大大提高了观测精度，对元、明时期天文研究的影响极为深远，郭守敬曾领导开展了全国范围的天文测量郭守敬根据观测的结果，于公元1280年3 月，制订了部准确精密的新历法《授时历》。这部新历法设定一年为365.2425天，比地球绕太阳一周的实际运行时间只差26秒。国际天文学会组织将美国在月球上发现的一座环形山和太阳系国际编号为2012的小行星，均以郭守敬的名字进行了命名。 4、徐光启（1562－1633年）字子先，号玄扈谥文定。上海徐家汇（今属上海市）人，明末著名的科学家，第一个把欧洲先进的科学知识，特别是天文学知识介绍到中国，终生从事研究天文、历法、水利、测量、数学、农学，较早接触并容纳西方文化，有《农政全书入《崇祯历书》和《几何原本》等著译，可谓我国近代科学的先驱者。 5、宋应星（公元1587—约1666年），字长庚，南昌奉新北乡（今宋埠乡）人。中国明朝著名科学家、诗人。着有《天工开物》。《天工开物》共有上、中、下3 卷，分为乃粒（粮食作物耕培）、粹精（谷物加工）、作咸（制盐）、甘嗜（制糖）、膏液（榨油）、乃服（养蚕与纺织）、彰施（染色）、五金、冶铸、锤锻、陶埏（陶瓷）、燔石（煤、石灰、矾石、硫黄、砒石）、杀青（造纸）、丹青（颜料与墨）、舟车、佳兵（兵器）、蘖（酒母、酒）及珠玉18部分，并附有123 幅图画。此书几乎论述了工农业所有部门的技术，反映了我国当时具有世界先进水平的许多生产技术和经验，对研究明代的科学技术和社会生产具有很高的价值，被欧洲学者称为“技术的百科全书”。 现代科学家5位 1、梁思成（1901——1972），广东新会人，梁启超长子。1924年，入美国宾夕法尼亚大学建筑系学习，获建筑硕士、美术学士学位。他代表中国参加了联合国大厦的设计，被普林斯顿大学赠予名誉博士学位。曾任北京市都市计划委员会
一模前任务型阅读专题练03 题组一 This time of year, thousands of college applicants wait for e-notices and auspiciously(吉利地)sized envelopes from schools, under terrible pressure from their parents, friends, teachers, and themselves. As to this, I offer some advice, which comes not only from a bit of experience, but also a bit of research: just cool out and continue, okay? Many parents and students think there is a world of difference between the lifelong outcomes of an A-minus student who gets into, say. Princeton, and an A-minus student who applies to Princeton but “only” gets into some less selective school, like Penn State or the University of Wisconsin. They assume that a decision made by faceless Ivy League admissions officers, to some extent, will mark the difference between success and failure in life. There are two important things to say about this stress. First, to put the anxiety into context, the kids applying to these schools are already doing quite well. Seventy percent of 29-year-olds don’t have a bachelor’s degree, and the majority of BAs are earned at non-selective schools that accept a majority of their applicants. Many of the applicants have already won life’s lottery. But if that doesn’t ease the nerves of the 40, 000 people waiting on Stanford or Penn, here is a more encouraging conclusion from economics. For most applicants, it doesn’t matter if they don’t get into their top choice, according to a paper by Stacy Dale, a mathematician at Mathematica Policy Research, and Alan Krueger, an economist at Princeton University. They tracked two groups of students—one that attended college in the 1970s and the other in the early 1990s. They wanted to know：Did students attending the most elite colleges earn more in their 30s. 40s. and 50s than students with similar SAT scores, who were rejected by elite colleges? The short answer was no. Or, in the author’s language, the difference between the students who went to super-selective schools and the students with similar SAT scores rejected by those schools and went to less selective institutions was “indistinguishable from zero.” What does that mean? It means that, for many students, “who you are” is more important than where you go. It’s hard to show that highly selective colleges add much earning power, even with the ir distinguished professors and professional networks. In addition, the decision of admissions officers isn’t as important as the sum of the decisions, habits, and relationships students have built up to this point in their young life. For the elite colleges themselves, the Dale-Krueger paper had additional, fascinating findings. It’s found that the most selective schools do make an extraordinary difference in life earning for minority students from less-educated families who are more likely to rely on colleges to provide the training and job networks with great

中国古代科学家的故事 李时珍——中国古代卓越的药物学家。 （公元1518年）生于湖北一个世医家庭。少年时代，常跟父亲和哥哥采集草药，或帮父亲抄写药方，听父亲讲解药物学知识。当时科举盛行，他14岁中了秀才。但他热爱医药事业，对八股文不感兴趣。因此，考举人三次落榜后，放弃了科举入仕的道路，一心做医生。 在行医当中，他发现当时的本草书收药不全，名称混乱，多有谬误。于是，下决心编写一部新的本草书。他详细研究了古代有关的本草学、医学等各类书籍，长期深入民间向广大劳动群众学习，到深山老林采集药材，开辟药园栽培药物，通过27年的埋头苦干，终于在61岁时写成举世闻名的《本草纲目》。该书不仅对我国古代本草学作了一次历史性总结，也将以前的化学知识予以系统化，并使之达到一个新的认识水平。该书载药1 892种，其中无机物达266种，而且药物的分类更详细，对一些较为混乱的物质命名加以更正。 葛洪--中国古代的炼丹家 中国是炼丹术出现最早的国家。虽然炼丹家以追求炼制长生不老之仙丹为目的，但采用的方法和使用的原料使他们成为最先开始进行化学实验和化学研究的人。在我国历史上研究炼丹术的人中，最著名的要算晋朝的葛洪（约281～361）。 葛洪自号抱朴子，出生于一个没落的官僚贵族家庭。13岁时，父亲去世，家境每况愈下。但是，他发奋读书，无钱买纸笔，就用木炭练字。他博览群书，对经书、史书、医书、百家之言等都认真学习研究，因此成为一个学识渊博的人。他一生对炼丹感兴趣。虽做过“关内侯”的官，但最终还是辞官不做，专事炼丹、制药，兼做医生。他长期远离尘世，从事炼丹研究，了解了许多化合物如铜青（硫酸铜）、矾石（明矾）、密陀僧（氧化铅）的性质，并进行包括炼丹、炼汞等在内的许多化学转变。除炼丹外，他还把炼丹中观察到的化学变化详细予以记载。他一生著作颇多，有《抱朴子》内外篇共一百六十篇，还有《金匮药方》一百卷，《时后要急方》四卷。其中《抱朴子·内篇》是他的主要炼丹著作。 张衡 张衡(公元78—139年)，字平子，南阳西鄂人(今河南省南阳市石桥镇夏村)，曾任尚书和河间相等职。 是我国东汉时期伟大的科学家、文学家、发明家和政治家，在世界科学文化史上树起了一座巍巍丰碑。 在地震学方面，他发明创造了“地动仪”(公元132年)，是世界上第一架测定地震及方位的仪器，比欧洲早1700多年。在天文学方面，他发明创造了“浑天仪”(公元117年)，是世界上第一台用水力推动的大型观察星象的天文仪器，著有《浑天仪图注》和《灵宪》等书，画出了完备的星象图，提出了“月光生于日之所照”的科学论断。在文学方面，他是我国文学史上一颗光辉灿烂的明星。

So the man walked to India which he had never visited. And when he got there, he was excited to see a lot of fruit. It was much expensive than that in his own country. At last, he found a big basket of red, long fruit and it was the cheapest in the shop. He bought a kilo and started to eat it. But after he ate some of it, Oh, my God! His eyes watered, his mouth burned and his face became red. He jumped up and down, but he continued to eat the fruit! Some people who were looking at him shook their heads and said, “You’re crazy, man. Those are chilies! You can’t eat so many and they’re not good for you. They are not fruit!” Then the man said, “No, I can’t stop. I paid money for them, and now I’ll eat them. It’s my money!” And you think that man was stupid, right? In fact, we sometimes do a lot of things like that. We spend a lot on the work, business or jobs. And even though we know there’s no more hope that things will change, we will continue just because we’ve put money, time and love into it. So even if you’ve lost something, let it go and move on.
