    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(能量) 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 do harm(危害) to them. The heat and light from the sun come in just the right quantities(数量) for life on the earth.
