帮忙找一篇阅读理解开头是这样的Life on earth depends on the sun.
Life on the earth depends on the sun.Day after day,we see its light and feel its warmth.The sun is far away from the earth.It is ninety-three million miles away from the earth.The sun is a large star.The earth is very small among its planets.Every day the sun sends out a great deal of heat and makes us feel hot.But we receive only a small part of the heat,because the sun is so far away from us and its heat loses more of its energy when it reaches the earth.We also receive a very small part of its light.This is enough for the growth of trees,plants,and humans.On the other hand,much heat and light would be harmful to them.The heat and light from the sun come in just the right quantities for life on the earth.地球上的生命依赖于太阳.日复一日,我们看到太阳的光芒,感受它的温暖.太阳距离地球很遥远.太阳相距地球九千三百万英里.太阳是一个大星球.地球在行星中是非常小的.每天太阳散发出巨大的热能,使我们感受了热量.但我们只得到了一小部分的热能,因为太阳离我们太遥远,当它的能量到达地球时已失去了大部分.我们也获得了它的一小部分光亮.这对树木生长,植物生长和人类生长已经足够.从另一方面说,过分的光和热将是对他们有害的.发自太阳的光和热满足了地球上的生命
