自然科学已经渗透到我们生活的各个方面，它在改善我们的 吃、穿、住、行等方面起着非常重要的作用。一起来了解一下！
Science exists in every aspect of our modern life.It is the noise of machines, cars, factories, and so on, which awakens us every day in the morning.The food we eat, the clothes we wear, the books and papers we read and the games we play—all have something to do with the application (应用) of science.
