With environmentalists pointing to the use of coal, oil and other fossil fuels as adding to the problem of global warming, the world is rushing to find other more environmentally friendly energy sources. Many countries are looking to nuclear power as the answer to their energy needs. Those who support using nuclear power point to the fact that the process for creating nuclear power produces huge quantities of electricity without producing any greenhouse gases. It seems to be the safest and most environmentally safe method for producing the largest amount of power, much more than solar or wind energy sources.
However, despite the many advantages of nuclear power, there are many groups who strongly advise against the use of nuclear power. Some groups point to concerns about possible terrorist attacks on nuclear plants or possible nuclear accidents that might result in widespread disaster. However, strange as it seems, many of the strongest voices against nuclear power are actually environmentalists, who oppose nuclear power because they claim it results in more greenhouse gases.
It may seem impossible, but in fact both facts are true: nuclear production itself produces no greenhouse gases, but nuclear power does, in fact, lead to the production of many greenhouse gases. How is this possible? The actual production of nuclear power does not let off any greenhouse gases at all; this is the fact that most governments and nuclear power companies point to, and it is, indeed, correct. However, those who oppose nuclear power point out the bigger problem: building and maintaining the nuclear power stations, mining the material used to produce the nuclear power and getting rid of the nuclear waste all create greenhouse gases, the very thing that nuclear power is supposed to avoid. The final point that environmentalists point out is that nuclear power is not a long-term solution to energy. One day uranium, the resource needed for producing nuclear power, will be at an end, the same problem the world is facing with coal and oil today.
1.What are many countries relying on to satisfy their energy needs according to the passage?
A. Coal. B. Oil.
C. Nuclear power. D. Other fossil fuels.
2.What disadvantages relating to the use of nuclear power are mentioned in the passage?
A. No greenhouse gases.
B. Killing more plants.
C. Widespread disasters and more greenhouse gases.
D. Making other energy sources not function well.
3.What’s the writer’s attitude towards the use of nuclear power?
A. Optimistic. B. Indifferent(漠不关心).
C. Pessimistic. D. Objective（客观的）.
4.Why do some environmentalists point out that nuclear power is not a long term solution to energy?
A. Because the resource for producing nuclear power will come to an end someday.
B. Because they think nuclear power gives off too many greenhouse gases.
C. Because the world is facing coal and oil shortages now.
D. Because more and more people are opposed to the use of nuclear power.

Nowadays, the most effective way to get power comes from burning fuels such as coal, oil and natural gas. They are less costly than other forms of energy. But burning fuels releases carbon dioxide, known as CO2 gas. Scientists agree that increasing amount of CO2 in Earth’s atmosphere is partly to blame for the rising temperature. It's clear the change in the atmosphere can have a big effect on the weather condition around the world.
However, keeping extra CO2 from entering the atmosphere is a difficult process. It’s not enough to advise people to burn the fuels in a clean way. As a result, scientists are looking for the best method for capturing the gas and storing it away from the atmosphere. Some of this research is taking place in Norway. The Technology Center in Mongstad (TCM) is the largest facility in the world for major testing of the CO2-capturing technology.
Tore Amundsen is its chairman. He says TCM has produced important information since it opened. The center is connected to a nearby electric power plant. It treats the waste gas from the plant using the chemical solvent (溶剂) which attracts the CO2 molecules. Then researchers take the solvent with the CO2 molecules and boil it. In this way, they can separate CO2 from the solvent and use the solvent again to capture more CO2. TCM can help capture 90 percent of the CO2 from the waste gas. With the current state of technology, it will increase the cost of electricity between perhaps 30% to 40% when the technology is applied to a power plant.
Experts say the best way to store the captured CO2 gas is to place it below the surface of the ground. Scientists can use the pumping technology to put it into areas left empty after the removal of oil or natural gas. But TCM does not pump the CO2 it captures. Instead, it releases the gas into the atmosphere. Tore Amundsen says only highly developed industrial nations can afford the pumping technology. So far, only Canada has a power plant that pumps CO2 gas. In total, there are just a few similar power plants in the world.
1.What can we learn about the CO2 gas?
A.It is usually found in coal.
B.It leads to world climate change.
C.It is a new kind of energy.
D.It does good to the atmosphere.
2.Scientists want to deal with CO2 gas by_________.
A.sending it into the atmosphere
B.finding clean fuels to use
C.collecting it with technology
D.stopping people from burning fuels
3.Which of the following is TRUE about TCM?
A.It works well in treating the waste gas.
B.It’s the only center to study the CO2 gas.
C.It was set up by Tore Amundsen.
D.It helps the power plant save a lot of money.
4.According to experts, the captured CO2 gas________.
A.can be used with oil or natural gas
B.should be put underground
C.must be allowed to go into the air
D.should stay in the chemical solvent

People who are hit by lightning and survive often have long-term effects. These may include memory loss, sleep disorders, muscle pain and depression.
Experts tell people to seek the safety of a building or a hard-top vehicle any time they hear thunder, even if it is not raining. They say lightning can strike as far as sixteen kilometers from any rainfall. Lightning can travel sideways. And at least ten percent of lightning happens without any clouds overhead that you can see.
People who are outdoors should make sure they are not the tallest thing around. Bend low to the ground, but do not lie down. And do not stand near tall object. Get away from water and anything made of metal. A car is safe, but don’t touch any metal inside.
Safety experts say people in buildings should stay away from anything with wires or pipes that lead to the outside. The National Weather Service says if you plan to disconnect any electronic equipment, do so before the storm arrives. Do not use a wired telephone. Do not use water. All these can carry electricity.
Some people think a person struck by lightning carries an electrical charge afterward. Experts say this is not true. It is safe to begin emergency treatment
Each year about four hundred people in the United States are struck by lightning. Last year forty four people died. The average is close to seventy. The National Weather Service says that is more than the number of people killed by severe storms.
1.According to the passage, which of the following is TRUE?
A．Lightning can happen even if there is no cloud.
B．Lightning can’t strike very far.
C．Lightning can’t travel sideways.
D．Don’t stay in a car when lightning happen.
2.We can learn from the passage that________.
A．it’s better to turn off any electronic equipment before the storm arrives.
B．a wired telephone is not safe to use in rainy days.
C．a person struck by lightning is said to carry an electrical charge afterward.
D．severe storms kill more people than lightning does.
3.The underlined word ”depression” probably means”_______”.
A．excitement B．a state of being forgettable
C．silence D．a feeling of being sad
4.The passage is mainly about______.
A．where people should stay in case of lightning

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.
1.What does the underlined word “it” in the last but one paragraph refer to?
A. wealth B. hydrogen C. electricity D. fuel
2.What is the problem with using hydrogen as energy?
A. It has by-products.
B. It has to be separated from other materials.
C. It will make energy too cheap.
D. It is too far away from us.
3.Why does the author give the example in the last but one paragraph ?
A. To tell us that we produce energy while using hydrogen power.
B. To tell us that hydrogen power does not produce pollution.
C. To show hydrogen power can stop war.
D. To show hydrogen power is cheap.
4.What is the author’s attitude about the future?
A. skeptical B. negative C. indifferent D. positive
5.What is the passage mainly about?
A. war and energy B. the future of hydrogen as an energy resource
C. the disadvantages of oil D. How to end war

It’s the oldest trick in the book: threaten the kids with a piece of coal, and they’ll behave in the name of Santa Claus.Some people say that parents are purposely taking in their kids by lying to them about Santa. Is it purposely cheating or playing along with the fantasy? There are always those stories about the kindergarten teacher or parent who would tell the kids there’s no Santa Claus, and they’d all start crying on the lost dreams.But if another teacher goes into a third-grade class and says there is a Santa Claus, they’ll all laugh at her.What I say is that if they’re at the age when they’re still believing,why bother to end it?
Then how long should parents pretend? Studies indicate that after eight,75 percent of kids don’t believe.That’s the first “S” word that parents have to deal with—it’s not sex. It’s Santa.So the parent has to sit down and say it in a gentle way. “Listen,Santa did exist. He was a person who gave to others and now that you’re older, you can give to others and be Santa,too.”Do you think if a kid who believes in Santa walks into a third-or-fourth-grade class, his friends are going to tell him in a gentle way?No.They’re going to make fun of him, and the kid is going to run home crying ,saying you lied to him. We all remember how the news is broken to us, so if we all remember, then there’s some significance or we would have forgotten it. And it’s better to have a memory if someone doing it nicely than some kids laughing at you.
Santa is also used as an instrument of guilt, because Santa knows everything. So even if the kids did bad things and got away with them, Santa knew. Still, Santa alone is not a good behavioral tool. You can’t, say, in January, play the Santa card to your child—because Christmas is too far away.
1.According to the first paragraph, parents should__________.
A. telling the kids that Santa does not exist
B. lie to their children on the problem of Santa Claus
C. not tell the truth if their children believe Santa Claus exists
D. tell children in advance in case of being laughed at by classmates
2.Why could your kid possibly be made fun of in the fourth grade?
A. He tells a lie that he believes in Santa.
B. He says Santa does exist in this world.
C. He expects gentle talks from his friends.
D. He gives to others and acts as Santa does.
3.The underlined part in the last paragraph most probably means to__________.
A. play cards with children happily
B. talk the kids out of doing something bad
C. clarify the truth of Santa to the kids in a gentle way
D. let the children figure the problem out by themselves
4.The author’s intention in writing this text is to__________.
A. introduce the detailed story of Santa Claus in all aspects
B. prevent children from being laughed at by fellow classmates
C. help children to understand whether Santa Claus is real or not
D. instruct parents how to explain the existence of Santa Claus to kids
