摘　　要：美丽的地球,植物、动物和人类的家园,是环绕太阳的第三颗行星和第五大行星。其他一些行星上也有大气、季节甚至水,但只有在地球上,所有这些元素才以正确的方式结合了起来。地球是太阳系中唯一已知有生命存在的地方。地球上的大多数地方都有四季更替,这是由地球的旋转和倾斜引起的。北半球的冬天,是南半球的夏天,反之亦然。地球周围有一层气体,保护它免受太阳的危害。大气中主要是氮气——约78%,还有氧气。Beautiful Earth, home to plants, animals and humans, is the third planet from the Sun. It's the fifth largest planet. Some of the other planets have atmospheres, seasons and even water, but only Earth combines all these elements in just the right way. Earth is the only place in the solar system1 where life is known to be found.Most of the places on Earth experience four seasons, caused by the earth9s rotation and tilt3. When it's winter in the northern hemisphere4, it's summer in the southern hemisphere, and vice versa". The Earth is surrounded by a blanket of gases that protects it from the sun. The atmosphere is mostly nitrogen'-about 78 percent. The atmosphere also contains oxygen.
