Research shows that humans switch from selfish to unselfish behaviour when they are watched. Do you?
A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box.
Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behaviour. Their report also referred to other research showing that this response of behaving well when watched is somehow coded into humans and people respond this way unconsciously, or without realising it.
It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.
The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption “I Want You”. It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.

“If there is one thing I’m sure about, it is that in a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.
The nature of what is news may change. What basically makes news is what affects our lives — the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do — as we develop a better understanding of how the brain operates and what our feelings really are.
It’s quite possible that in the next century newspapers will be transmitted (传送) electronically from Fleet Street and printed out in our own home. In fact, I’m pretty sure that how it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read — sports and international news, etc.
I think people have got it wrong when they talk about competition between the different media. They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn’t happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet, it’s never really pleasant to read something just on a screen.
1. What is the best title for the passage?
A. The Best Way to Get News B. The Changes of Media
C. Make Your Own Newspaper D. The Future of Newspaper
2. What will probably be on in the newspaper made by yourself?
A. Sports and international news. B. A menu of important news.
C. The most important news. D. What you are interested in.
3. From the passage, we can infer _______.
A. newspapers will win the competition among the different media
B. newspapers will stay with us together with other media
C. television will take the place of newspaper
D. the writer believes some media will die out
4. The phrase “feed off” in the last paragraph means _______.
A. depend on B. compete with C. fight with D. kill off

Nick Campbell sat at the side of the road and wondered what to do next. He looked at the second-hand Harley Davidson he’d bought from a back-street garage back home in Miami at the beginning of his trip six weeks before.
For years he had dreamt of crossing the United States from east to west by motorbike and he’d finally decided that it was now or never. He’d given up his job, sold his car and set off for the journey of his dreams. He’d been lucky, or so he thought, to find this old Harley Davidson and had bought it for a very reasonable price —— it had cost him just $600. But five kilometers from Atlanta, he had run out of luck. The motorbike had broken down.
He pushed the bike into town and found a garage. The young mechanic told him to leave the bike overnight and come back the next day. The following morning, to his surprise, the man asked if the bike was for sale. “Certainly not,” he replied, paid his bill and hit the road.
When he got to Kansas the old machine ran out of steam again. This time Nick thought about selling it and buying something more reliable, but decided to carry on. When the bike was going well, he loved it.
However, in Denver, Colorado, the bike broke down again so he decided to take it to a garage and offer it for sale. The mechanic told him to come back in the morning.
The next day, to his amazement, the man offered him $2,000. Realizing the man must be soft in the head, but clearly not short of money, Nick asked for $ 3,000. The man agreed and they signed the papers. Then the mechanic started laughing. In fact it was several minutes before he could speak and when he could he said, “That’s the worst deal you’ll ever make, boy."
He removed the seat. On the underside was the inscription (铭文):
‘To Elvis, love James Dean.’
1. Harley Davidson here refers to a _________.
A. car B. truck C. garage D. motorbike
2. Which of the following did Nick value most?
A. Harley Davidson. B. His job.
C. His dream to travel. D. His car.
3. The underlined word “soft” in the 6th paragraph is closest in meaning to ______________.
A. clever B. crazy C. honest D. kind
4. At the end of the story, Nick must have felt very __________.
A. sorry B. delighted C. excited D. moved

What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.
1．What makes a scientist according to the passage?
A. The tools he uses. B. His ways of learning.
C. The way he uses his tools. D. The various tools he use
2．“The scientist, however, goes one step further,” the author says this to show________.
A. the importance of information
B. the importance of thinking
C. the difference between scientists and ordinary people
D. the difference between carpenters and people with other jobs.
3．A sound scientific theory should be one that________ .
A. does not only work under one set of conditions at one time, but also works under the same conditions at other times
B. leaves no room for improvement
C. does not allow any change even under different conditions
D. can be used for many purposes
4．What is the main idea of the passage?
A. Scientists are different from ordinary people.
B. The theory of relativity.
C. Exactness is the core（核心）of science.
D. Exactness and way of using tools are the keys to the making of a scientist.

Schedules, as the 21st century people know, simply did not exist in the 17th and 18th centuries. We are upset if a plane arrives an hour late. Our ancestors weren’t upset if an April ship didn’t show up until June. They began to worry in July and were often happy when it showed up in August. When a long-distance ship finally did get to the port, the whole city became busy and excited. Businessmen hurried down to check the goods they had ordered. The ship would probably stay in port for at least three days, often a week, to take on businessmen, give the sailors a rest, find out about the latest news, weather conditions, and so on.
Travel time could only be approximate. One never knew when the winds would be good. So even though “average sailing time” was given, time could change considerably, shortening the voyage by up to 25% or putting it off by up to 500% or more! The average run from England to Boston was about a month and a half, but there were also voyages of three months. One voyage in 1640 lasted six months!
Travel time is not the same in both directions, due to the winds and currents. This is especially true in the Caribbean, where winds are from the southeast the entire year. Ships sailing west across the Atlantic spend longer than ships sailing east, and the contrary winds can prevent a ship from actually making it to the harbor even if it gets close. One ship was held off the North Carolina coast for 17 days before being able to land!
1. What can we learn from the first paragraph?
A. No sailor was allowed to have fun when the ship reached land.
B. People in ancient times didn’t care about other people’s safety.
C. The ship would leave for a voyage when all of the preparations were made.
D. A long-distance ship would create a lot of excitement in the place where it landed.
2. According to the passage, travel time can’t be fixed due to ___________ .
A. the people at the port B. average sailing time
C. the changeable climate D. the businessmen and the sailors
3. The underlined word “currents” in the third paragraph means __________ .
A. the movement of water B. the movement of winds
C. direction of the traveling ship D. travel time of ships

A．often gave others surprises	B．was full of imagination
C．was a gifted musician	D．invented the roller skates
