Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution. It’s bad to all living things in the world.
Polluted air from cars, planes and factories is so thick that it is like a quilt(被子) over a city. This kind of quilt is called smog(煙霧). Many countries are making rules to fight pollution. Factories must now clean their water before it is thrown away. And they mustn’t blow dirty smoke into the air. We need to do many other things. We can put waste things in the dustbin and not throw it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.

New Energy in the Twenty-first Century Energy from the wind.
All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.
Energy from the water
When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大壩) to use this kind of power, and building dams is very expensive.
Energy from the earth
There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地?zé)岬? San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.
Energy from the sun
Solar panels(鑲板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.

The police find most criminals (罪犯) because somebody tells them who the criminals are. They find other criminals by using science and their computers. When there is a bank robbery (搶劫), the police first look through their computers for the names of the bank robbers that they know about. Then they go and talk to any of these robbers who are not in prison (監(jiān)獄). They ask them where they were when the robbery happened. If any of these people cannot give a good answer, the police will often use science to find out if one of them is the robber.
Many criminals leave something of themselves at the places of the crimes like a fingerprint or a hair. Or they take something away on their shoes or clothes, like dirt or animal hair. If they leave behind some of their blood or their hair or a piece of skin, it will have their DNA inside it.
Everyone’s DNA is different and their fingerprints are also different. So, if a criminal cuts himself during a robbery or leaves his hair, or even a small piece of skin, scientists can find out what his DNA is. The police can then ask the person they think is the robber to give them his hair or some blood and see if it has the same DNA. Many criminals are in prison today because of this kind of evidences .
根據(jù)上文內(nèi)容判斷正 ( T ) 誤( F )
小題1:Usually the police find criminals because they use their computer.
小題2:The police do not usually ask criminals who are in prison about a crime because these criminals could not have done it.
小題3:The most useful evidences that criminals leave at the places of their crimes are things with their DNA in them.
小題4:Many criminals usually take something away only on their shoes after the crimes.
小題5:The story is about a bank robbery.

  Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life.
Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregivers. This is how babies learn to connect and communicate with other human beings.
One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby.
The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again.
Another study shows how mothers can strongly influence social development and language skills in their children.
Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children’s activities and did not interfere (干涉) unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression (消沉).
The children of depressed women did not do as well in tests as the children of women who did not suffer from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.
These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring, even when they suffered from depression.
小題1: According to the passage, which of the following is NOT the factor that influences intelligence development in babies?
A.The environment.B.Mother’s sensitivity.
C.Education before birth.D.Their peers (同齡人)
小題2: What is the purpose of the experiment in which newborn babies heard the stories?
A.To prove that babies can learn on the first day they are born.
B.To prove that babies can learn before they are born.
C.To show mothers can strongly influence intelligence development in their babies.
D.To indicate early education has a deep effect on the babies’ language skills.
小題3: Which group of children did the worst in tests of language skills?
A.The children of women who did not suffer from depression.
B.The children of depressed but caring mothers.
C.The children of depressed mothers who cared little for their children.
D.The children with high communication abilities.
小題4: What is the main idea of the passage?
A.Scientific findings about how intelligence develops in babies.
B.Scientific findings about how the environment has an effect on babies’ intelligence.
C.A study shows babies are not able to learn things until they are five or six months old.
D.Scientific findings about how babies develop before birth.

“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).
Close your eyes and imagine you are living in the next two centuries or more. You'll be living in a world filled with smart robots, which will be helping you to take care of your children, or your elderly parents in your home. You'll live much longer thanks to the medicine made by genetic (基因的) science. And mankind may be going farther in space than ever before-you will be living on the moon or Mars.
How should we view the changes that wait for us in the future? Should we be optimistic (樂觀的)about the years ahead, or worried about what the future holds? Some scientists and experts are having a discussion about how technology, science and society will develop in the future.
"I'm looking forward to the day when more technology will come to my life," says John Searle, a professor at the University of California Berkeley Philosophy, "because I think further research in such areas as genetics, physics, chemistry and medicine will help us to overcome poverty, improve health, and make life longer."
Hugh Herr, at MIT's Biomechatronics Group, considers very powerful weapons as concern over the future. Another is the growing role of technology in our lives."Machines’ taking over what humans do is not a good thing," Herr says.
That is a similar concern shared by Daniela Cerqui, a social and cultural scientist. "I am afraid that the long-term future we are building will have no space left for human beings," says Cerqui. "The main values of our society are related to information that must progress as quickly as possible, and computers are much better than humans in these tasks ."
小題1: The second paragraph mainly tells us ________.
A.how science will develop in the future
B.how people will live in a modern society
C.what life would be like in the future
D.what computers will bring to our society
小題2:From Paragraph 4 we can infer that ___________.
A.John Searl is optimistic about the future
B.we should wait to see the changes in the future
C.John Searl worries much about what the future holds
D.further science research will be helpful for making life longer
小題3: The underlined word "That" in the last paragraph refers to________.
A.The poverty problem in the future
B.Machines’ taking over what humans do
C.The technology of weapons
D.The health problem of humans
小題4:The best title for the passage can be “___________”.
A.The Future--Full of Hope or Concern
B.Great Changes Will Take Place in the Future

Would you like to have an electric car? We will see this kind of cars soon in America. These quiet, clean cars run on electricity. Carmakers will start selling electric cars in 2011.
The world’s population will jump from 6.8 billion to 9 billion by 2050. The need for cars will jump with it. But the oil(石油) won’t keep up with the number of cars on the road. So the price of oil will go up.
Electric cars aren’t perfect just yet. It can take eight hours to charge(充電) a car for only 100 miles of driving. And the distance(路程) that cars can go depends on driving conditions(條件). How far it travels depends on the weather and traffic.
Price is a problem, too. Electric models cost much more than oil-powered cars. The good news is that electric-car technology is getting better. As it does, the prices of this kind of cars are dropping.
To charge the car, the US Department of Energy is paying for at least 10,000 charging stations around the country. Private businesses are also getting ready for it. It will cost about $3 for each charge.
Carmakers are coming up with other ways to make the car cleaner and cheaper. Cars may run on clean diesel(柴油). So who knows what will power the car you may be driving in 10 years? The chances are that it will be something that’s clean and easy.
