Ⅳ.阅读理解
Solar energy for your home is coming.It can help you as a single home owner.It can help the whole country as well.Whether or not solar energy 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 that’s 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 won’t have to worry about the sun’s running out of energy for another several billion years or so.Besides，the sun doesn’t 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 won’t need as much.That means we can cut down on our pollution problems.
With all these good points，why don’t 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 nation’s energy supply.
1．What’s this passage mainly about?
A．Something about solar energy and pollution.
B．Solar energy.
C．Energy and pollution.
D．Energy and money.
2．Solar energy can help us________.
A．escape punishment from nature
B．become home owners
C．get rid of present energy
D．save our precious fuel
3．The sun is an endless source of energy，and it will not run out of energy for________.
A．several million years
B．several hundred years
C．several billion years
D．several thousand years
4．Which of the following statements is TRUE?
A．Energy from coal would not pollute our living environment.
B．Energy from natural gas would not pollute our living environment.
C．Energy from the sun would not pollute our living environment.
D．Energy from oil would not pollute our living environment.
5．Solar energy is now in its infancy，________.
A．but in the future it will become an important part of our nation’s energy supply
B．so we will build more power plants
C．and the supply of electricity will be rationed throughout the country
D．so we don’t need it

Ⅲ.1.A　[分数或百分数修饰名词作主语时，谓语动词的单复数取决于分数或百分数后面的名词的单复数。句子的主语surface是不可数名词，谓语动词用单数，陈述的是事实，用一般现在时。]
2．C　[形式主语只能用it；(化学)发生反应用react with。故答案为C项。]
3．C　[scientific科学的，作定语修饰experiment。scientific experiment科学试验，符合句意。]

7．B　[equipment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。 ]
8．C　[句中with复合结构“with the metals...at the top，and the metals...at the bottom”作定语，修饰a table；宾补由介宾短语充当；and连接的两个宾语后接了一个由that引导的定语从句。]
9．D　[keep...out of...是固定短语，意思是“使 ……不进入……，防止……进入……”。]
10．B　[there be 结构中，句子主语air是不可数名词，故用there is，所以选B项。]
