前言

阅读既是理解和吸收语言文化信息的重要手段之一，又是语言文化信息的最便捷的输入源。我国教育部新制定的全日制义务教育和普通高级中学《英语课程标准》对学生的阅读技能从三级到九级提出了明确的要求。在目前国内外的各种英语测试中，阅读理解所占的比重越来越大。为此，我们特向你推荐“中学英语拓展阅读丛书”(Timed Readings Plus)。本丛书含有以下3个子系列：社会科学(Social studies)、自然科学(Science)及数学(Mathematics)，由上海外语教育出版社从美国McGraw Hill Glencoe公司引进出版。社会科学和自然科学各有10个分册，社会科学每册有24课，自然科学每册有25课，每课两篇阅读材料；数学有5个分册，每册有15课，每课两篇阅读材料。本丛书语言地道，知识面广，信息量大，能有效训练学生的阅读理解能力，提高他们的阅读速度。每课的第一篇阅读材料篇幅长400单词左右，侧重训练学生的快速阅读能力；阅读理解题则主要检查学生是否能在快速阅读后掌握阅读材料中的事实和材料所传达的思想。每课中的第二篇阅读材料较短，着重训练学生的阅读技巧，如：从上下文中猜测生词的含义，找出作者的观点，得出中心思想，排列事件顺序，推断作者的论点等。因此，我们认为它是一套训练学生阅读速度及阅读理解能力并能同时开拓他们视野的拓展型丛书，适合外国语学校初二及以上年级学生和非外国语学校高中学生课内、外使用。怎样使用本系列丛书呢？我们有以下的一些阅读策略供大家参考。1．阅读时，要集中注意力。2．用一分钟阅读标题，并思考以下问题：我是否了解这一话题？我从这个话题中能学到什么？这个话题引起了我怎样的思考？3．重点阅读文章第一句和最后一句，因为第一句和最后一句往往是作者提出自己观点和总结全文观点的关键句子。4．快速阅读全文以获得材料所传达给你的信息。如遇到含有姓名、日期或数字等的内容，你应该放慢速度，以便记住这些内容。怎样才是一个快速阅读者？

章节摘录

For centuries people dreamed of space travel. This dream began to seem possible with the development of high-flying rockets in the early 1900s. A rocket travels through the air by shooting out a stream of hot gases. These gases come from the burning of fuel.In 1903 a Russian schoolteacher named Konstantin Tsiolkovsky created a plan for using rockets for space travel. His plan was the first one to include accurate scientific calculations. About 20 years later， a U. S. scientist named Robert Goddard built the first rockets that could reach high altitudes. In Germany in the 1920s， Hermann Oberth wrote a book that persuaded many powerful people that the new rockets made space flight possible. During World War II， German scientists designed large rockets that could travel long distances while carrying high explosives. After the war， scientists from Germany went to the United States and the Soviet Union to help design space rockets.Those two countries were soon in a race to space. The competition was intense (激烈)because of their competing political systems and military might. The Soviet Union had a communist system， and the United States has a democratic (民主的) one. The two rivals also had developed hydrogen bombs. People in the United States became concerned when the Soviets were the first to launch a space satellite， which was called Sputnik. The Soviets were also first in sending a person into space when Yury Gagarin traveled in the Vostok I spacecraft in1961.    The U.S. government became determined that its space program would be the first toput a person on the Moon. The U. S. space program built a series of Apollo spacecraft， which were powered by huge Saturn 5 rockets. In 1969， Apollo 11 took three men to the Moon. Neff Armstrong became the first person to set foot on the Moon.    After the Soviets lost the race to land people on the Moon， they built the first space station. The United States also built a space station. The space stations proved that people could live and work in space. The Soviet Union and the United States linked two spacecraft in space on a joint mission. This ended their “space race. “ Today a much larger space station， assembled (安装) with the cooperation of several countries， orbits Earth.
