can save your money depends on many things.Where you live is one factor and the type of home you have is another.Things like insulation (绝缘材料)，present energy costs，and the type of system you buy are added factors.Using solar energy can help save our precious fuel.As you know，our supplies of oil and gas are very limited.There is just not enough on hand to meet all our future energy needs.Sooner or later Mother Nature will say thats all.The only way we can delay hearing those words is by starting to save energy now and by using other sources，like the sun.We wont have to worry about the suns running out of energy for another several billion years or so.Besides，the sun doesnt offer as many problems as other energy sources.For example，fossil fuel (矿物燃料) adds to already high pollution levels.With solar energy，we will still need sources of energy，but we wont need as much.That means we can cut down on our pollution problems.With all these good points，why dont we use more solar power？There are many reasons for this.The biggest reason is money.Until now，it was just not practical for a home owner to put in a solar unit.There were cheaper sources of energy.All that is changing now.Solar costs are starting to equal the costs of oil and electricity.Experts say that gas，oil and electricity prices will continue to rise.The demand for electricity is increasing rapidly.But new power plants will use more gas，oil or coal.Already in some places the supply of electricity is being rationed (限量供应)Solar energy is now in its infancy (初期)It could soon grow to become a major part of our nations energy supply.1Whats this passage mainly about?ASomething about solar energy and pollution.BSolar energy.CEnergy and pollution.DEnergy and money.2Solar energy can help us_.Aescape punishment from natureBbecome home ownersCget rid of present energyDsave our precious fuel3The sun is an endless source of energy，and it will not run out of energy for_.Aseveral million yearsBseveral hundred yearsCseveral billion yearsDseveral thousand years4Which of the following statements is TRUE?AEnergy from coal would not pollute our living environment.BEnergy from natural gas would not pollute our living environment.CEnergy from the sun would not pollute our living environment.DEnergy from oil would not pollute our living environment.5Solar energy is now in its infancy，_.Abut in the future it will become an important part of our nations energy supplyBso we will build more power plantsCand the supply of electricity will be rationed throughout the countryDso we dont need itcontract

experiment科学试验，符合句意。4D祈使句用动词原形开头，故选D项。5Dadd.to.把添到/加到上。6Aput sth.in order把事物按顺序排列。7Bequipment设备，是不可数名词，electrical equipment电器，符合句意。instrument仪器，是可数名词；technology指总的科学技术；technique指具体的技术，都不合题意。
