39 Sail to the Stars

Chapter 1 What Is an Astronaut? The word astronaut means "star sailor." Astronauts travel into space to study the moon, planets, and stars. You must train at a special school to be an astronaut. You also must be a test pilot, scientist, or engineer. test pilot: a person who tests a new aircraft Russian Astronauts Russian astronauts are called cosmonauts. This means "universe sailor." NASA stands for National Aeronautics and Space Administration. If you want to be an astronaut, you need to study at the National Aeronautics and Space Administration (NASA). That is where all American astronauts are trained. At Spacecamp, kids train like real astronauts.

第一章宇航员是什么? astronaut这个词的意思是“星际水手”。 宇航员进入太空研究月球、行星和恒星。 要成为一名宇航员，你必须在一所特殊学校接受训练。 你还必须是一名试飞员、科学家或工程师。 试飞员:测试新飞机的人俄罗斯宇航员俄罗斯宇航员被称为宇航员。 意思是“宇宙水手”。 NASA是美国国家航空航天局的缩写。 如果你想成为一名宇航员，你需要在美国国家航空航天局(NASA)学习。 这是所有美国宇航员接受训练的地方。 在太空营，孩子们像真正的宇航员一样训练。

Chapter 2 How are Astronauts Chosen? Every year, thousands of people apply to become astronauts. But only about 100 are chosen. These people go to the Johnson Space Center in Texas. For one week, they take tests and answer questions. apply: ask to be a part of These people all want to be astronauts. They are at the Johnson Space Center. At the space center, trainers look for people who work hard and work well with others. Then the trainers choose who might be a good astronaut. Every two years, NASA chooses only about 20 of these people to train as astronauts. Alan B. Shepard, Jr. was America's first astronaut in space.

第2章宇航员是如何被选中的? 每年，成千上万的人申请成为宇航员。 但只有大约100人被选中。 这些人去了德克萨斯州的约翰逊航天中心。 在一周的时间里，他们要参加测试并回答问题。 例如:这些人都想成为宇航员。 他们在约翰逊航天中心。 在航天中心，培训师寻找那些努力工作并能很好地与他人合作的人。 然后训练人员会选择谁可能成为一名优秀的宇航员。 每两年，美国国家航空航天局只从这些人中挑选大约20人进行宇航员培训。 小艾伦·b·谢泼德是美国第一位进入太空的宇航员。

Chapter 3 What Training Do Astronauts Need? Basic astronaut training takes one year. Students in basic training are called astronaut cadets. Astronaut cadets first learn about aircraft safety. They study math, science, and technology. Cadets also learn how to live without gravity and work in a spacesuit. Astronauts need training to learn how to float safely in space. Astronauts train in a KC-135 jet aircraft. In this aircraft, they discover how it feels without gravity. Astronauts train in simulators, too. Simulators look and work like spacecraft, but they don't leave the ground. Astronauts practice in simulators before they go on a real mission. practice: to do again and again to become better The KC-135 flies up and down. It can make people feel sick!

宇航员需要什么训练? 基本的宇航员训练需要一年时间。 接受基本训练的学生被称为航天员学员。 宇航员学员首先要学习飞机安全知识。 他们学习数学、科学和技术。 学员们还将学习如何在没有重力的情况下生活和穿着宇航服工作。 宇航员需要训练来学习如何在太空中安全漂浮。 宇航员在KC-135喷气式飞机上训练。 在这架飞机上，他们发现了没有重力的感觉。 宇航员也在模拟器中训练。 模拟器看起来和工作起来都像宇宙飞船，但它们不会离开地面。 宇航员在执行真正的任务之前会在模拟器中进行练习。 KC-135飞机上上下下地飞。 它会让人感到恶心!

These swimmers are watching the astronauts in white suits. Astronauts also train in a swimming pool. Here they learn to work in space suits. The water helps astronauts feel like they are floating in space. Suit Up Space suits keep astronauts' body temperatures normal. There is oxygen in the suits so astronauts can breathe. After a year of basic training, astronauts learn how to fly a space shuttle. Then new members are chosen for a space mission. They must learn to work together. Language DETECTIVE Space: Space has the s sound spelled with the letter c. Find another word with the s sound spelled with the letter c on page 4. About 10 weeks before a mission, a team of astronauts begins to train together. This team is from the space shuttle Atlantis.

这些游泳者正在观看穿着白色衣服的宇航员。 宇航员也在游泳池里训练。 他们在这里学习穿着太空服工作。 这种水能让宇航员感觉自己漂浮在太空中。 宇航服能使宇航员的体温保持正常。 太空服里有氧气，所以宇航员可以呼吸。 经过一年的基本训练后，宇航员学习如何驾驶航天飞机。 然后新成员被选中执行太空任务。 他们必须学会合作。 Space: Space的s音和c音一起拼。 在第四页找到另一个带有s音的单词，这个单词的拼写是字母c。 在执行任务前大约10周，一组宇航员开始一起训练。 这个团队来自亚特兰蒂斯号航天飞机。
