10.As long as the sun shines, the earth will not run out of energy. The sun pours more energy on earth than we can ever use. Most of that energy comes to us as heat and light. Energy from the sun is called solar energy.
Anything to do with the sun is called "solar". The word began with the Roman word for the sun and their god of the sun, who was called Sol. Solar energy is a safe kind of energy. It doesn't make pollution or have dangerous leftovers. That is why scientists and investors are experimenting with ways of harnessing（治理利用）the sun to do some of the jobs fossil fuels have been doing.
But to make the sun do work like that, they have to solve some problems. They have to collect the sun's energy. Collecting sunshine is not easy, unless you are a plant. Sunshine is not easy to store, either. You can't fill a tank with it or put it in the wood box. You can not move it through a pipe or a wire. You can not just turn it on.

正误判断题：
If you travel by air across the center of Africa or South America, you fly over forests for thousands of kilometers. These great forests are the oceans of trees. There are thousands and thousands of different kinds of plants and animals.
However, the world's forests are getting smaller all the time. We are cutting down the trees because we need wood, and we need more farmland. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear?
