1、Unit 2,Para. 1 运动医学专家经过多年的观察，发现耐力运动员，特别是女性，经常会缺铁。普渡大学研究人员进行的一项新的研究表明：即使是适度的锻炼，也可能会降低女性血液中的铁含量。,Para. 4 缺铁在女性中是很常见的，每四个十几岁的少女中有一人缺铁，每五个18至45岁的女性中有一人缺铁。而在积极锻炼的妇女中这一比例更高，女耐力运动员中，缺铁者比例则高达80%。莱尔说，这意味着“太多女性忽视了自己摄入的铁含量。” 育龄女性危险最大，因为月经是铁流失的重要原因之一。此外，许多保健意识太强的女性也很危险，因为她们拒绝食用牛肉或羊肉，而这些肉中含有的铁最易被吸收。而且，由于女性常常为了控制
2、体重而节食，从而未能摄取足够的含铁丰富的食物，结果可能导致缺铁。,Para. 10 如果铁含量低，就要去看医生，以确定是否该通过调整饮食或服用铁质补剂来校正不足。一般说来，解决问题的最好方法是在食谱中增加含铁丰富的食物，因为铁质补剂可能存在严重缺陷。 “服用铁质补剂可能使人想呕吐，有时甚至还会引起中毒。最好的铁来源，以及唯一最易为身体所吸收的铁来源，是肉、鸡和鱼。其他较好的铁质来源包括枣、豆类和一些多叶绿色蔬菜。”,Unit 2,1. Sports medicine experts have observed for years that endurance athletes, particu
3、larly females, frequently have iron deficiencies. Now a new study by a team of Purdue University researchers suggests that even moderate exercise may lead to reduced iron in the blood of women.,4a. Iron deficiency is very common among women in general, affecting one in four female teenagers and one
4、in five women aged 18 to 45, respectively. But the ratio is even greater among active women, affecting up to 80 percent of female endurance athletes. This means, Lyle says, that “too many women ignore the amount of iron they take in”.,4b. Women of childbearing age are at greatest risk, since their m
5、onthly bleeding is a major source of iron loss. Plus, many health-conscious women increase their risk by rejecting red meat, which contains the most easily absorbed form of iron. And because women often restrict their diet in an effort to control weight, they may not consume enough iron-rich food, a
6、nd are liable to experience a deficiency.,10a If iron levels are low, talk with a physician to see if the deficiency should be corrected by modifying your diet or by taking supplements. In general, its better to undo the problem by adding more iron-rich foods to the diet, because iron supplements ca
7、n have serious shortcomings.,10b. Supplements may produce a feeling of wanting to throw up, and may be poisonous in some cases. The best sources of iron, and the only sources of the form of iron most readily absorbed by the body, are meat, chicken, and fish. Good sources of other forms of iron inclu
8、de dates, beans, and some leafy green vegetables.,Unit 3,Para. 1 海德中学的办学宗旨是：如果你向学生传授诸如求真、勇敢、正直、领导能力、好奇心和关心他人等美德的话，学生的学习成绩自然就会提高。该校的创始人约瑟夫高尔德声称学校的教学很成功。海德中学位于缅因州巴思市，每年的学费高达1.8万美元，因其教导问题少年有方而闻名遐迩。,“我们并不把自己看作一所专为某一类孩子而开设的学校，”马尔科姆高尔德说。他是约瑟夫的儿子，毕业于海德中学，现任海德中学校长。“我们把帮助孩子培养一种生活方式看作自己的职责，办法是倡导一整套能影响所有孩子的价值观
9、念。”,Para. 12a 在解释自己的教育方法时，乔高尔德指出，对传统的教育体制不能只是改革。他说“无论怎样改革”，用马和马车“是改革不出汽车的”。 海德中学认为“每一个人都有自己的独特潜能”，这种潜能的基础是品格而不是智力或财富。良知和苦干受到推崇。,Para. 12b 成功由不断进步来衡量，而不是由学习成绩来评定。学生必须相互负责。为了避免美国中学使用的其他品格培养方案所引发的争议，高尔德解释说，“全力以赴”这一概念并不是要强迫学生接受某一套道德原则或宗教观念。,Unit 3,Para 1 The Hyde School operates on the principle that if
10、 you teach students the merit of such values as truth, courage, integrity, leadership, curiosity and concern, then academic achievement naturally follows. Hyde School founder Joseph Gauld claims success with the program at the $18,000-a-year high school in Bath, Maine, which has received considerabl
11、e publicity for its work with troubled youngsters.,2. “We dont see ourselves as a school for a type of kid,” says Malcolm Gauld, Josephs son, who graduated from Hyde and is now headmaster. “We see ourselves as preparing kids for a way of life by cultivating a comprehensive set of principles that can
12、 affect all kids.”,Para 12a Explaining his approach to education, Joe Gauld says the conventional education system cannot be reformed. He notes “no amount of change” with the horse and carriage “will produce an automobile”. The Hyde School assumes “every human being has a unique potential” that is b
13、ased on character, not intelligence or wealth. Conscience and hard work are valued.,Para 12b Success is measured by growth, not academic achievement. Students are required to take responsibility for each other. To avoid the controversy of other character programs used in US schools, Gauld says the c
14、oncept of doing your best has nothing to do with forcing the students to accept a particular set of morals or religious values.,如何做好防震准备 Para. 1a 从理论上说，人们希望知道地震什么时候发生，破坏程度会如何。在日本和中国，人们长期以来一直相信地震是可以预测的。在日本，科学家在陆地上和海洋中铺设电线，以监测它们的运动。而中国人的传统做法是观察动植物以获取地震的警示信号。,Unit Six,Para. 1b 例如，中国人注意到，地震之前母鸡的行为会有所异常：
15、它们夜晚不肯进笼。他们还注意到，蛇会爬出地穴而冻死，狗会狂吠不已，甚至那些平常很安静的狗也会叫个不停。日本的阪神地震发生之前，有报告说大批鱼群游到了水面。,Para. 1c 有些鸟，如鸽子，也显得特别聒噪，据说地震前它们飞行的方式也与往常不同。也许最有趣、也最容易测量的，是地震前地下水发生的化学变化。实验数据似乎表明，地震前地下水中氡的含量会增高。,Para. 7a 尽管科学家们仍无法预测地震，但对地壳中的大板块如何移动，板块间的压力如何，地震如何发生，某地区发生地震的一般概率为多少，他们了解得越来越多。在不久的将来，精确预测地震将成为可能。,Para. 7b 然而，即使可以预测，居住在地震频
16、发区的人们还是应尽力预防灾难，办法是建造能够抵抗地表运动的房屋，同时做好个人准备。在挽救生命和防止家庭损失方面，这些预防措施会发挥很大的作用。教育人们如何在地震中求生，应该是所有政府规划和地震研究项目的重点所在。,Para. 1a Ideally, people would like to know when an earthquake is going to happen and how bad it will be. In both Japan and China, people have long believed that earthquakes can be forecast. In Japan, scientists have wired the Earth and sea to detect movements. The Chinese have traditionally watched animals and plants for warning signs of earthquakes.,How to Prepare for Earthquakes,Para
