People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill(减肥药), because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔)each day. Low-calorie Diets Do Not Work
The reason people cannot lose weight by starving themselves is that their metabolism(新陈代谢)will detect any major drop in calories and it will then adjust(调整)itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2,500 calories per day and not gain any weight.
Low-fat Diets Do Not Work
Many people in today’s society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low fat lifestyle.
Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.
What is the main reason why people are overweight?

A．They eat the wrong foods at the wrong time.

B．They eat food with lots of calories.

C．They don’t take any weight loss pills.

D．They burn many calories every day.

The article is written in order to _______.

A．tell readers not to buy low-fat or non-fat food

B．tell readers how to lose weight

C．tell readers about an important scientific discovery

D．call on people to lose weight and stay healthy

To realize the aim of your weight loss plan, you should ________.
a. do exercise every day
b. eat meals at the right time
c. eat fruits and vegetables
d. eat low-fat or sweet food
e. eat the proper foods at each meal

A．a, b, c, d

B．a, b, d, e

June 26, 2000 — the Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遗传的) map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging human life. But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.
For the last few years, the genetic advances in the developing field of biotechnology have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密码) have opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes(基因) connected with terrible diseases as yet, and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections(传染), and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.
1.Why did the scientists work hard at mapping the human genome?
A. Because the human genome can destroy many illnesses.
B. Because the human genome's completion can help them get rid of many diseases.
C. Because they wanted to be better known than others.
D. Because the human genome can provide a lot of chances of work.
2.Which of the following is NOT true?
A.If the genes can be found, scientists can study many new ways to cure illnesses.
B.The scientists have made great progress in connecting the genes with the cancers.
C. Many medical companies show great interest in drawing the human genome map.
D. The United States began the Genes Study early in the 19th century.
3.The author suggests that the Human Genome Project can cause _______.
A. the policy makers to feel very worried and careful
B. the scientists to work harder.
C. many people to find work easily.
D. a lot of companies to produce many new drugs.
4.The main idea of this article is about _______.

In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65 percent increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991and 2008.
The study, published in the online issue of the American Journal of Preventive medicine,found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2008. The most common types of rock climbing –related injuries were fracture(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%).Climers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quartes of the injuries occurring as the result of a fall. The severity of related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury, explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalizaton rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.
1.Which body part is most likely to get injured for a climber ?
A.The arm        B.The ankle     C. The knee     D. The hand
2.How many women climbers in American got injured while climbing a rock between 1991 and 2008 ？
A.About 40,000   B.About 30,000    C.About 20,000 D.About 10,000
3.The severity of climbers’fall-related injures is mainly related to ______.
A.the height of the fall.           B.the climber’s age.
C.the climber’s health condition    D.the climber’s climbing experience.
4.The underlined word “demonstrates” in the last paragragh can be replaced by ________.

A teenager says he convinced the White House that he was Iceland’ s president and managed to schedule a call with George W.Bush , but was found out before he got to talk to the US president.
“My call was transferred around a few times until I got hold of Bush’s secretary and managed to book a call meeting with Bush the following Monday evening ,” Vifill Atlaso, 16, told Reuters.

“They told me the CIA had called the National Commissioner of the Icelandic Police and asked if the police could try and find out where I received that phone number from,” said Atlason.
The teenager said he was unable to recall where he had discovered the telephone number of the White House.
“I know I’v had it on my phone card for at least four years now and that an Icelandic friend gave it to me, but I don’t remember who,”he said.
At a White House news conference on Monday, Bush’s spokeswoman Dana Perino said her understanding was that Atlason had called a public line “that anybody can call”, according to a transcript(记录).

Television, which made its first serious appearance in 1939, did not become common until the early 1950s. Since then, millions of children have grown up in front of the set, and many people now worry about the effect that TV has on the young, and on society in general. Educators, psychologists, and crime experts wonder if television should be abolished(取消). Many ordinary parents wish it had never been invented. Why are they so afraid? Is television as harmful as they think it is?
Like almost anything else, television has its good and its bad sides. One should surely thank its inventors for the joy and interest that they have brought into the lives of the old, the sick, and the lonely -- all those who, without it, would have no pleasure and no window on the world.
In truth, television has opened windows in everybody's life. No newspaper has ever reached so many people and shown so clearly what was happening right now in their own country and everywhere else. TV not only gives the news instantly, it also shows it in pictures more powerful than words. It can be said that TV has brought reality to the public. Millions of people now have seen the effects of a battle, a flood, a fire, a crime, disasters of every sort on the screen.
Unfortunately, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world. They want to imitate what they see. They do believe that the violence they see is normal and acceptable. By the time they are out of high school, most young people have watched about 15,000 hours of television, and have seen about 18,000 killings or other acts of violence. All educators and psychologists agree that the "television generations" are more violent than their parents and grandparents,
According to the same experts, the young are also less patient. Used to TV shows, where everything is quick and entertaining, they do not have the patience to read an article without pictures; to read a book that requires thinking; to listen to a teacher who doesn't do funny things like the people on children's programs. And they expect all problems to be solved happily in ten, fifteen or thirty minutes. That's the time it takes on the screen.
It is certain that television has deeply changed our lives and our society. It is certain that, along with its benefits, it has brought many serious problems. To these problems we must soon find a solution because, whether we like it or not, television is here to stay.

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hunted animals. They used to paint pictures of the animals they wanted to catch and kill. Pictures of this kind have been found on the walls of caves in France and Spain. No one knows why they were painted there. Perhaps the painters thought that their pictures would help them to catch these animals. Or perhaps human beings have always wanted to tell stories in pictures.
About 5,000 years ago, the Egyptians and other people in the Near East began to use pictures as kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet.
The Egyptians used to record information and to tell stories by putting picture-writing and pictures together. When an important person died, scenes and stories from his life were painted and carved on the walls of the place where he was buried. Some of these pictures are like modern comic strip stories. It has been said that Egypt is the home of the comic strip. But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it.
By the year 1,000 BC, people who lived in the area around the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letters of the Greek alphabet. The Romans copied the idea, and the Roman alphabet is now used all over the world.
These days, we can write down a story, or record information, without using pictures. But we still need pictures of all kinds: drawing, photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the street, and on the walls of the places where we live and work. Pictures help us to understand and remember things more easily, and they can make a story much more interesting.
1. Pictures of animals were painted on the walls of caves in France and Spain because ______.
A. the hunters wanted to see the pictures
B. the painters were animal lovers
C. the painters wanted to show imagination
D. the pictures were thought to be helpful
2. The Greek alphabet was simpler than the Egyptian system for all the following reasons      EXCEPT that _______.
A. the former was easy to write
B. there were fewer signs in the former
C. the former was easy to pronounce
D. each sign stood for only one sound
3. Which of the following statements is TRUE?
A. The Egyptian signs later became a particular alphabet.
B. The Egyptians liked to write comic-strip stories.
C. The Roman alphabet was developed from the Egyptian one.
D. The Greeks copied their writing system from the Egyptians.
4. In the last paragraph, the author thinks that pictures ___________.
A. should be made comprehensible             B. should be made interesting
C. are of much use in our life                 D. have disappeared from our life
