Nobody could live without the sun. The sun gives us light and heat, and light and heat give us life. Without the sun, we would be in darkness.
Without light or heat, the earth would be very cold and there would be all snow and ice. Then all plants and animals would die.
We don't see the sun at night, because our earth is always turning round the sun, and only one side of the earth sees the sun.
When we see the sun on the side of the earth, it is day to us.
【参考译文】
离开太阳没有人能生存。太阳给了我们光和热，而光和热给了我们生命。没有太阳，我们就会在黑暗中。
没有光和热，地球会太冷，所有的东西都变成了雪和冰。那么所有的植物和动物都会死亡。
晚上我们见不到太阳，因为地球总是绕着太阳转，只有地球上的一面能见上太阳。
当我们在地球的一面见到太阳时，那就是白天。
