热点60 煤炭资源等与能源安全
一、阅读理解

Right now, the biggest source of energy(能源) in the world is fossil fuel(矿物燃料). Fossil fuels are oil, gas, and coal (煤). More than 80 percent of the world’s energy comes from fossil fuel. There are many problems with fossil fuel. One problem is that when fossil fuel is burned, it pollutes the air. Also, when we take fossil fuel from the Earth, we often cause a lot of harm. Another problem is that we’re running out of it.
A big source of energy for many countries is nuclear power(核能).Thirty-one countries use nuclear power. A lot of ships also use it.
Nuclear power has some advantages(优点). First of all, we can’t run out of nuclear power. Nuclear power does not make the air dirty. Also, if a country has nuc lear power, it doesn’t need to buy as much oil from other countries.
However, there are also a lot of problems that come with nuclear power. For example, nuclear accidents are very serious. In 1986, there was a nuclear accident in Russia. In the next 20 years, about 4,000 people got sick and died. In 2011 there was another very serious nuclear accident in Japan. That was several years ago, but Japan is still trying to clean up the nuclear waste from the accident.
Many people don’t want nuclear power in thei r countries. They say that it’s not safe. A lot of people in the United States, Russia, France, Japan, India, and many other countries want their countries to use safer and cleaner ways to get electricity(电力). Sometimes they get together to show their strong disagreement with nuclear energy.
Many people hate nuclear energy, but more and more countries are using it. One reason for this is that the world is using more and more energy. We just don’t have enough fossil fuel. However, if we use nuclear power, then we may have more serious problems in the future.

Thousands of years ago, people didn’t know that the Earth moved. They thought the sun really did move across the sky. The Greek God Helios was said to drive the sun across the sky with his chariot. But now, the way people think has changed. Nowadays, it is the sun that drives a “chariot” around the sky.
What do I mean by this? Well, quite simply, there is now a plane (or “chariot”) that is powered by the sun. It has special parts on its wings. These parts absorb power from the sun. They get so much power that the plane can still fly even at night. In Greek mythology, Helios had to take a break at night. It seems we’re finally even more powerful than the gods themselves.
This plane is called Solar Impulse. It will fly across the US next month. This is very important for the future of the world.
Why is solar energy important? Well, other kinds of energy are known to cause problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal and gas to make energy. The heat and chemicals created by burning these things give us power. But if we use power from the sun, we don’t have to burn
anything and there will not be any pollution.
Solar energy is not ready yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. The Solar Impulse plane could pretty much keep flying forever. Of course, the sun’s light will fina lly run out too one day, but not for another 5 billion years. That’s a pretty long flight.
5. The Solar Impulse ________.
A. has to take a break at night
B. is powered by chemicals
C. has already flown across the US
D. is a special kind of plane
6. What can we learn about solar energy in this passage?
A. People can use solar energy forever.
B. Solar energy is the most popular energy.
C. Using solar energy makes the Earth cleaner.
D. Creating solar energy is hard but important.
7. What does the underlined wo rd “absorb” in Paragraph 2 probably mean?
A. look for
B. take in
C. give away
D. make up
8. What’s the passage mainly about?
A. The special plane of solar energy.
B. The ways of making use of energy.
C. The story of the Greek God Helios.
D. The uses and advantages of solar energy.
【答案】5. D 6. C 7. B 8. D

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do
when it runs out? Perhaps we will go back to use horses, carriages and bicycles.
In the Second World War, some people didn’t use gas made from petroleum（石油）in their cars. They made gas from wood and plants instead. The car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all our trees to make gas; we ne ed our trees for other things, too.
Besides different types of gas, we can also use electricity（电）to run our cars, but first we must make electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines（涡轮机）and make electricity more easily and cheaply. We are also able to get power from the ocean tides（海潮）. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.
Which of these ways will be used to run our cars in the future?
9. When might people have to go back to use horses and carriages?
A. When they are poor.
B. When they run out of oil.
C. When they need more exercise.
D. When there aren’t any big trees in the world.
10. What did some people use to make gas in the Second World War?
A. Water.
B. Coal.
C. Wood and plants.
D. Tides.
11. How many ways are suggested to make electricity in the passage?
A. 2.
B. 5.
C. 4.
D. 3.
12. According to the passage, which of the following statements is TRUE?
A. There is more petroleum than we can use now.
B. Trees are needed for some other things besides making gas.
C. We got electricity from ocean tides in the old days.

According to the Xinhua News Agency, on August 28, 2003. The Tibet Autonomous Region which enjoys over 3000 hours of sunlight every year has become the most important place in the country in terms of solar energy development and use. Thanks to the development of solar energy, electricity has become available to 200,000 people in Tibet. Solar energy is also used for heating and cooking. Using solar energy can save Tibet 135,000 tons of coal every year. Do you know what solar energy is? What is solar cooking?
Solar energy is often used to heat houses directly (the sun enters through the windows, and makes the rooms warm). Solar energy is also often used to heat water (a solar collector is put in direct sunlight, and heats the water in the water tank).
Solar cookers use no electricity or gas, need no firewood, and produce no air pollution. The simplest type of solar cooker is a box cooker: an insulted box painted black on the inside and covered with glass or plastic. Sunlight enters the box and heats the food inside. A simple cooker can be made out of cardboard, and can reach temperatures over 250F. A higher-quality cooker can reach temperatures up to 425 F.
Besides cooking food, solar cookers can also be used to purify drinking water, and heat water for laundry. Solar energy can make people’s lives much better.

Have you ever heard of “a ball of energy”? People often use it to describe a very active child. But today we tell about an invention called the sOccket that is a real soccer ball of energy. Julia Silverman explains that in fact the sOccket is a portable generator (便携式发电机).
Julia Silverman and Jessica Matthews developed the sOccket as part of a group project for an engineering class at Harvard University, the USA. There are mechanisms (装置) in a sOccket. When you kick, hit or throw it, energy is then kept in it by these mechanisms instead of disappearing into the environment. Then the user can put something directly into the ball, like a lamp, or a mobile phone charger (充电器) so that they can get energy from it. For every fifteen minutes of the game play, the sOccket can provide enough electricity for an LED lamp for three hours. The ball can store up to 24 hours’ electricity.
It was reported that nearly one and a half billion people in the world had no electricity to use last year. And most of them live in sub-Saharan Africa and in India and other countries in Asia.
Julia and Jessica both had experiences in developing countries before they began the project. They knew that power shortages are a serious problem in many areas. There is an energy crisis (危机) in the world. And besides that, there are a lot of health problems because what people use instead of the electricity are harmful choices like kerosene (煤油) lamps. They produce a lot of smoke.
Julia says the sOccket ball is one small solution to a big problem. They hope their sOccket ball will shine more light on the problem of power shortages. It offers people a chance to put their energy into the world’s most popular sport and get some energy in return.21. What does “a ball of energy” refer to in this passage?
A. A very active child.
B. A normal soccer ball.
C. A soccer ball generator.
22. How can the sOccket get energy?
A. By getting recharged.
B. By being kicked, hit or thrown.
C. By getting energy from the environment.
23. From the passage we can infer people in _______ are less short of energy or electricity.
A. Asian countries like India
B. sub-Saharan Africa
C. developed countries
24. Which of the following statements is NOT right?
A. The world has a serious problem of power shortage at present.
B. Julia Silverman and Jessica Matthews are famous American inventors.
C. Both Julia Silverman and Jessica Matthews have been to developing countries.
25. What can we know from the last two paragraphs?
A. The sOccket not only can produce electricity but also is good for health.
B. The sOccket has fully helped people to solve the problem of power shortages.
C. The sOccket makes it possible for people to get energy by doing different sports.
【答案】21. C 22. B 23. C 24. B 25. A

Natural resources come from the earth. And they are limited. This means that they will not 36 forever. Some are renewable, like trees, For example, you can plant a new tree when you 37 one down. Others are not renewable, like the coal. Once it is dug out of the 38 and used, it is gone. People realize the 39 that Earth's nature resources are limited, and they decide to do something to help save 40 . When you try to save one kind of natural resources, you had better use less of it, 41 it will be used up so fast. One way that people save the fuel, such as gasoline, is by riding a bicycle or walking when the 42
is short instead of driving. Water is a very important natural resource because we all need it to keep 43 . We can save water by making sure that our pipes and taps do not leak. We can also make 44 choices to save water, like only using the dishwasher or washing machine, not making the water keep running. Everyone can make contributions to 45 natural resources.
