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 doesnt 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 suns energy. Collecting sunshine is not easy, unless you are a plant. Sunshine is not easy to store, either. You cant 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.

Th、e two Mongolian brothers knew that hot air rose. If they could fill a large balloon _3_ hot air, they thought it would rise into the air and fly. They were right.

自然资源与公共资源在开发利用中有什么资源经济规律？

正确答案: 自有资源是指所有权和使用权都明确属于产权人的资源，产权人可以使个体，集体或国家。资源的拥有者会把资源看成总资产的一部分，当资源价格上升幅度大于银行利润时，产权人倾向于保留资源，当预计资源价格上升幅度低于银行利润率时，产权人倾向于尽快开采资源，二八卖资源所得的钱存入银行。
公共资源是指生产者可以自有利用、但所有权不属于生产者的资源。在一定的经济条件下，以公共资源形式存在的生物种群数量会稳定在一个水平上，在这个水平上对其进行开发利用的收益恰好等于其成本。这种经济与生物的双重平衡关系叫做生物经济平衡。
