Have you ever wondered why birds sing? 1 After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy.
2 Their singing is actually a warning to other birds to stay out of their territory. Do you know what a "territory" is? A territory is an area that an animal, usually the male, claims(声称) as its won. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. 3 If so, you have actually scared the stranger away without having to fight him. 4 But he expects an outsider almost all the time, especially at nesting(筑巢) season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird' s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
5 Most of it has to do with attracting males and setting up territories.
| A．A bird does the same thing. |
| B．Maybe you thought that they were just happy. |
| C．Shouting loudly is just like a bird's screaming. |
| D．You can see that birds have a language all their own. |
E. Probably this would be enough to frighten him away.
F. However they sing most of the time for a very different reason.
G. So, just like human beings, birds sing for almost the same reasons.
Jim suffered heart problems. In conversation he expressed little joy and it seemed that his life was drawing to a close.
When his heart problems led to operation, Jim went through it successfully, and a full recovery was expected. Within days, however, his heart was not beating properly. Jim was rushed back to operation, but nothing was found to explain the cause of his illness. He died on the operating table on the day before his 48th birthday
Dr. Bruce Smoller, a psychologist, had had many conversations with him, and the more he learned, the stranger he realized Jim's case was. When Jim was a child, his father, a teacher, suffered a heart attack and stayed home to recover. One morning Jim asked his father to look over his homework, promising to come home from school at noon to pick it up. His father agreed, but when Jim returned his father had died. Jim's father was 48.
“I think all his life Jim believed he killed his father,” Dr. Smoller says. “He felt that if he had not asked him to look at his homework, his father would have lived. Jim had been troubled by the idea. The operation was the trial he had expected for forty years. “ Smoller believes that Jim willed himself not to live to the age of 48.
Jim's case shows the powerful role that attitude plays in physical health, and that childhood experiences produce far-reaching effect on the health of grown-ups. Although most cases are less direct than Jim's, studies show that childhood events, besides genes, may well cause such midlife diseases as cancer, heart disease and mental illness.

The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.
Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.
Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.
The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business
To raise money for the idea, he toured the city’s private companies which fund new business and found a supporter in the finance group Mint. He introduced his idea to four of Mint’s directors and won their support. Mint has committed around £500,000 to MyHabs and taken a share of 30 per cent in Mr. Dunlop’s business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.
Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.
For music events, the cardboard houses will be ordered online and put up at the sites by the Myhabs team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior (外部的) advertising space.
The biggest festivals attract tens of thousands of participants, with Glastonbury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.
11. “Eco-friendly tents” in paragraph 1 refer to tents _______.

It is difficult for doctors to help a person with a damaged brain
Without enough blood, the brain lives for only three to five minutes More often the doctors can’t fix the damage Sometimes they are afraid to try something to help because it is dangerous to work on the brain The doctors might make the person worse if he operates on the brain
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

C. have the blood cooled down D. operate on the brain
A. a, b, c, d B. c, a, b, d C. c, b, d, a D. b, c, d, a
10. Which of the following is not true?

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.
