尽管科学家努力确保万无一失，但是意外还是可能发生。苏联“联盟11号”和美国“挑战者”号航天飞机上的所有宇航员都在执行任务时死亡。这些灾难让每个人都感到悲伤和失望，但是探索宇宙的渴望却从未停止过。是因为人们坚信太空探索的重要性，哪怕面临巨大的风险。仍在工作的一个例子是国际空间站。它绕地球运转，并有来自不同国家的宇航员在宇宙飞船上，为太空提供了持续的人类存在。

Unit 1 | Reading and ThinkingWHY DO WE CELEBRATE FESTIVALS我们为什么庆祝节日？Festivals are celebrated all around the world. They have a wide range of origins, such as the seasons of the year, religions, famous figures, and important events. Every festival has its different customs and unique charms. However, no matter how different they may seem, all over the world, the spirit of sharing joy, gratitude, love, or peace is common in all festivals.世界各地都庆祝各种节日。
节日的由来五花八门，比如时节、宗教、著名人物及重要事件。
每个节日都有其不同的习俗和独特的魅力。
然而，无论它们多么迥异，在世界各地，分享快乐、感恩、友爱或和平的精神存在于所有节日之中。
Of all the traditional festivals, the harvest festival can be found in almost every culture. This important agricultural festival takes place after all the crops have been gathered in. People celebrate to show that they are grateful for the year’s supply of food. In ancient Egypt, the harvest festival was celebrated during the springtime—the Egyptian harvest season. It featured a parade and a great feast with music, dancing, and sports. Today, in some European countries, people decorate churches and town halls with flowers and fruit, and get together to celebrate over a meal. During the Mid-Autumn Festival in China, families gather to admire the shining moon and enjoy delicious mooncakes.在所有的传统节日中，丰收节几乎可见于每一种文化之中。

⼈教版⾼⼀英语必修三Unit4课⽂翻译⼈教版⾼⼀英语必修三Unit 4课⽂翻译Unit 4 Astronomy:the science of the stars —Reading—HOW LIFE BEGAN ON THE EARTH地球上⽣命的起源No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a "Big Bang" that threw matter in all directions. After that, atoms began to form and combine to create stars and other bodies.没有⼈确切知道地球是怎样开始形成的，因为在很早很早以前它就形成了。
然⽽，⼀种普通为⼈们所接受的理论是：宇宙起源于⼀次⼤爆炸，这次⼤爆炸将物质投射到四⾯⼋⽅。
然后，原⼦开始形成并结合成恒星和其他天体。
For several billion years after the "Big Bang", the earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface.⼤爆炸后好⼏⼗亿年过去了，但地球还只是⼀团尘埃。
