Setting the scene
Science is probably humanity's greatest achievement. Scientific discoveries have changed the way we live. Alexander Graham Bell invented the telephone that revolutionized the way we communicate. The Wright brothers invented the airplane that made long distance commuting easier. More recently, Bill Gates and Steve Jobs have made desktop computing and iPhones part of our everyday life. It is nearly impossible to imagine living without them.
科学可能是人类最大的成就。科学发现改变了我们的生活方式。亚历山大·格雷厄姆·贝尔（Alexander Graham Bell）发明了电话，彻底改变了我们的沟通方式。赖特兄弟发明了使长途通勤更容易的飞机。最近，比尔·盖茨和史蒂夫·乔布斯（Steve Jobs）使台式机计算和iPhone成为我们日常生活的一部分。几乎不可能想象没有他们的生活。
Almost everything that we encounter on a day-to-day basis is, in some way, related to science. Even when we are sleeping, science is there to explain why we need to sleep and what takes place while we are sleeping. Because of this, science education is essential to life. In this unit, you will learn the characteristics of science and how our daily life is related to science.
在某种程度上，我们每天遇到的几乎所有事物都与科学有关。即使我们在睡觉，科学也可以解释为什么我们需要睡觉以及我们在睡觉时发生了什么。因此，科学教育对生活至关重要。在本单元中，您将学习科学的特征以及我们的日常生活与科学的关系。
