The word began with the Roman word for the sun and their god of the sun, who was called Sol. Solar energy is a safekind of energy. It doesn't make pollution or have dangerous leftovers. That is why scientists and investors areexperimenting with ways of harnessing（治理利用）thesun 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 aplant. Sunshine is not easy to store, either. You can't fill a tank with it or put it in the wood box. You can notmove it through a pipe or a wire. You can not just turnit on.(4)、What are the problems facing scientists who wantto use solar energy?A It is not easy to collect.B It is not easy to store.C It is not easy to find out.D both A and B.学生答案：D得分:2.5分172.5分Sixteen-year-old Maria was waiting in line at the airpor t in Santo Domingo.
