探究与巩固河南科学技术出版社系列答案Waste can bring a lot of problems. Although China is rich in some resources（资源）， we are short of（缺乏）others, for example，fresh water（淡水）. It is reported that we will have no coal（煤or oil to use in 100 years. So if we go on wasting our resources，what can we use in the future and where can we move？Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life，we can do many things to prevent waste from happening，for example， turn off the water taps（水龙头） when we finish washing，turn off the lights when we leave the classroom，try not to order more food than we need and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.

Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel.

The new cars are different and they can run on many different kinds of fuels .
Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels . One kind of them runs on a special fuel cell which is filled with a gas called hydrogen(氢气). ___1.___? They are very clean , and don’t give off bad fumes(烟雾) when they run .
The man who makes fuel cell cars is excited about the technology .__ 2.___ Once we use oil up , it will take millions of years for more oil to form. Since gasoline is made from oil , that could be a problem for companies that make traditional cars , and for drives . __3.__
?? Buses that run on hydrogen fuel cell power are being tested on the road . They could become a common form of transportation in the near future
A. The fuel cell cars are also better in another way . B. However, it won’t be a problem for cars that run on fuel cells .. C. He says we will never run out the fuel, but we may run out of oil. |
4.What do you think of this kind of new cars ? Why ?
Oil is so important that it is sometimes called “black gold”. Almost half of our energy comes from oil. We use it to run our cars and factories and to heat our homes, offices and schools. Many everyday things are made from oil. Your shirt may have oil in the material. The soap you wash your hands with might also be made from oil. Your favorite plastic toy is made from oil.
Oil is hard to find, because it is trapped deep under the earth. Once the only way people knew there was oil someplace if it leaked（渗漏）out of the ground. Today, however, we have many ways of finding oil. One tool measures（测量）the pull of gravity. Places where gravity is weaker are more likely to have oil. Another tool is sound waves（声波）. Sound waves travel through different kinds of rocks at different speeds. We can use them to find the rocks that have oil in them.
We need a lot of oil, and we are using up the oil wells we know about. Soon we must find new ways of looking for this “black gold”.
1.Which of the following isn’t the
way to help find oil?
A. Sound waves travel through different kinds of rocks at different speeds.
B. People measure the pull of gravity to know if there is oil.
C. Sound waves tell us where the oil has leaked out of the ground.
D. People know there is oil if it leaks out of the ground.
2.Which of the following does the passage lead you to believe?
A. Oil was firstly found by measuring gravity.
B. Many things are made from oil.
C. We will never run out of oil.
D. Our lives would not be different if we didn’t have oil.
3.The main idea of the whole story is that ________________.
A. many things are made from oil
B. we must find new ways of looking for oil
C. people spend a lot of time looking for oil
D. oil is important for us but hard to find
