Recently, a scientist did some experiments. He left a group of 4-year-olds in a room with a bell and a candy. If they rang the bell, he would come back and they could eat the candy. If, however, they didn’t ring the bell and waited for him to come back on his own, they could then have two candies.
In the videos of the experiments, he can see the children hiding their eyes, trying to exercise self-control so they can wait and get two candies. The results are different. Some broke down and rang the bell within a minute. Others lasted 15 minutes.
The children who waited longer went on to get higher academic scores. They got into better colleges and had better adult success. The children who rang the bell quickest were more likely to have received worse teacher and parental evaluations (评价) 10 years later and were more likely to have drug problems at age 32.
The experiments are worth noting because people spend a lot of time thinking about how to improve education, and how to become rich. But when the result is not good, they will come back to ask “How do we get people to get the sort of self-control that leads to success?” This is to enter the world of human nature.
So these experiments, along with everyday experience, tell us that self-control is most important. Young people who can sit through sometimes boring classes to get a degree can work hard in order to learn a language well. They can avoid drugs and alcohol. For people without self-control skills, however, school is a series of failed and painful experience. No wonder they drop out and their later life is a group of foolish ideas, such as drug use, stealing and so on.
1.The scientist did some experiments to ________.
A.find good ways of training children to learn
B.show that children’s education is important
C.test children’s self-control and later success
D.test children’s intelligence of ringing the bell

New research suggests that dogs might be able to help save diseased citrus trees.
A group of scientists trained dogs to use their sense of smell to detect a crop disease called citrus-greening. The disease has affected orange, lemon and grapefruit trees in the American states of Florida, California and Texas.
The dogs can detect the disease weeks to years before it appears on tree leaves and roots, the researchers report. A study on their findings was published recently in the Proceedings of the National Academy of Sciences. The report says using dogs is also faster, less costly and more exact than having people collect hundreds of leaves for lab analysis.
Timothy Gottwald is a researcher with the U. S. Department of Agriculture and a co-writer of the study. He told The Associated Press,” This technology is thousands of years old-the dog's nose. We've just trained dogs to hunt new prey. ”
Citrus-greening is caused by a bacteria (细菌) that is spread by a tiny insect that feeds on the leaves and stems of citrus trees. Once a tree is infected(感染), there is no cure. The disease has also hurt citrus crops in Central and South America and Asia. In one experiment involving grapefruit trees in Texas, trained dogs were correct 95 percent of the time in telling the difference between newly infected trees and healthy ones. ”The earlier you detect a disease, the better chance you have at stopping an epidemic(流行病）by removing infected trees, ”Gottwald said.
Matteo Garbelotto studies plants at the University of California, Berkeley. He says the new research shows that dogs can detect an infection well before current methods. Garbelotto has been involved in similar research but had no part in the new study.
Laura Sims is a plant scientist with Louisiana Tech University. She praised the steps taken to find out if the dogs were detecting the bacteria itself or a plant's reaction to an infection. To do that, the researchers infected different kinds of unrelated plants with the bacteria in a laboratory. The dogs were still able to pick out the infected plants.
Gottwald said, “You've seen dogs working in airports, detecting drugs and explosives. Maybe soon you will see them working on more farms. ”
1.According to the research, trained dogs can
A.help infected trees recover from diseases
B.recognize a crop disease in its early stage
C.cause fruit trees to grow faster than usual
D.reduce the cost of planting some fruit trees
2.What does the underlined part “new prey” in Paragraph 4 refer to?
A.Infected plants. B.Fruit trees. C.Tiny insects. D.Favourite foods.
3.Why did the researchers do experiments on unrelated plants?
A.To further prove the findings. B.To explore the plant diseases.
C.To present different opinions. D.To discover a plant's reactions.
4.How does Gottwald feel about the future use of this new method?
A.Doubtful. B.Confident. C.Uninterested. D.Curious.

Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.
The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with (处理,对付)these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “ diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes (中风) are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol (酒精) or tobacco (烟草), probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.
Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones (家畜). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors (祖先). We eat more sugar. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin C.
People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.
1.According to the passage, people in industrialized nations would be much healthier if they ate___________.
A. more food than humans living 10,000 years ago did.
B. as much food as humans living 10,000 years ago did
C. more kinds of food eaten by people living over 10,000 years ago.
D. more of the same kind of food eaten by people over 10,000 years ago.
2.New kinds of sicknesses have been found because __________.
A. the human body has changed compared with humans who first appeared on the earth.
B. the way we live has changed a little.
C. our body can’t deal with the changes in life style.
D. the way we live today is proper for the human body.
3.What is the main cause that people suffer from a lot of new sicknesses?
A. Ancient people did a great deal of physical exercise.
B. People today have a lot of alcohol.
C. People today have more tobacco.
D. Food today is quite different from that of ancient times.
4.According to some scientists , Stone-age people were much healthier than people today because they ate a lot of _____________.
A. milk and other dairy products. B. wild animals, fresh wild vegetables and fruits.
C. salt and sugar D. grain foods

Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for(满足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.
1. The passage tells us that Charles Darwin .
A. was a great English scientist
B. always liked doing the experiments that others thought difficult
C. thought even the simplest thing was important
D. didn’t get well with others
2.The underlined phrase “set aside” most probably means .
A. throw away B. store up
C. put to use D. realize
3. The author of the passage tries to .
A. convince us that Charles Darwin, Galileo and Newton are the greatest scientists in the world
B. draw the conclusion that basic sciences are simple things
C. prove that two sheets of paper, with the same size and shape, will fall at the same speed
D. draw our attention to everyday happenings around us
4.Which of the following is TRUE?
A. Darwin really did foolish experiments.
B. According to some people Darwin did foolish experiments.
C. It is believed by all the people that things could be important though they seemed to be simple.
D. Galileo and Newton worked out ancient Greek physics.

Most adults firmly believe that as kids reach their teens, they start to take crazy risks that get them in trouble. Do teenagers simply love taking all risks much more than adults? A recent study suggests otherwise.
Scientists designed a simple experiment involving 33 teenagers and three other age groups. In the experiment, the researchers tried to distinguish between two very different kinds of risk-taking. The first they called a willingness to take known risks (when the probability of winning is clear) and the second they called a willingness to take unknown risks (when the possibility of success is uncertain).
The study offered participants the opportunity to play two kinds of games. They had the chance to win money, with one game offering a known risk and the other offering an unknown risk. On each round of the game, each participant had to choose between taking a sure $5 and known or unknown risks of winning a lot more. If on one particular round they had picked the $5 for sure choice, then they got $5. But if on that round they had chosen to take a risk, the rules of the game will determine whether or not they had won. If they did win, they went home with between $8 and $125. And, of course, if they lost, they went home with nothing.
What the scientists found was really quite surprising. It turned out that the average teenager was very hesitant when risks were known—more careful than college students or parents-aged adults, and about as careful as grandparent-aged adults. This means that when the risks were known, teenagers were not risky in their behavior at all. Only when the risks were unclear did teenagers choose them more often than other groups. Under those kinds of conditions, they were much more willing to take a risk than any other group.
So, what does all of this mean? The research suggests that adults should probably focus more energy on trying to educate teenagers about risks than limiting them. Teenagers who understand the risks associated with a decision are more likely to be careful in their behavior.
1.This experiment was carried out by
A.dividing the teens into three groups
B.comparing the reactions to different risks
C.giving equal amount of awards to the participants
D.observing the emotional changes of the teenager
2.When facing known risks, teenagers tended to be ________.
A.ambitious B.cautious C.anxious D.curious
3.Which group in the study were more likely to take unknown risks?
A.Teenagers. B.College students. C.Parent-aged adults. D.Grandparent-aged adults.
4.According to the study, parents should focus on ________.
A.guaranteeing children to be careful B.setting age limits on dangerous activities
C.respecting teens to make their own choices D.guiding teens to learn more about the effect of risks
