A listener has written from China for advice about how to lose weight. Michael in Shanghai says he is 26 and has fought against obesity (过度肥胖) for most of his life.

Obesity , a severe weight problem, is a complex (复杂的) condition. A doctor may advise taking medicine along with changing one’s the way that he or she behaves. Experts say that the most successful weight—loss plans include a well-balanced diet and exercise.

People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use. To lose weight, you can reduce the number of calories you absorb (吸收), increase the number you use, or both.

A recent study looked at four of the most popular dieting plans in the US. Researchers at Stanford University in California studied over 300 overweight women, mostly in their thirties and forties. Each woman went on one of the four plans: Atkins, The Zone, Ornish or LEARN. The women attended diet classes and received written information about the food plans.

At the end of the year, the women on the Atkins diet had lost the most, more than four and one-half kilograms on average. They also did better on tests for cholesterol levels and blood pressure.

Christopher Gardner, who led the study, says the Atkins diet may be more successful because of its simple message to eat less sugar. He also says that the advice to increase protein in the diet leads to more satisfying meals. He says that there was not enough money to study men, but that men would probably have similar results.

Last week, another report based on thirty-one studies suggested that only a small number of people have long-term success with dieting. Most dieters regained (重新获得) their lost weight within five years and often they become more overweight ( 超重的). But those who kept the weight off generally were the ones who exercised.

New York Times---( DINITIA SMITH )Tomorrow is the 433d anniversary of Shakespeare’s birth. A recent survey shows that more people are watching him, reading him and studying him than ever before.

Consider the recent yearly conference of the Shakespeare Association of America in Washington, where more than 600 people who study or admire Shakespeare from 18 countries took in topics like ‘‘Whither Attribution Studies,’’ ‘‘Unpopular Shakespeare’’ and ‘‘Sex Me Here,’’ a talk on breast-feeding and Lady Macbeth.

‘‘The national media is saying that fewer students’ taking Shakespeare,’’ Barbara Mowat, the editor of The Shakespeare Quarterly, observed in a speech at the conference. ‘‘But Shakespeare is thriving.’’ The association’s membership has increased by a third since 1990.

The Shakespeare business is so good these days that W. W. Norton is introducing a huge new collections of the plays into the already crowded field just in time for tomorrow’s birthday anniversary. Priced at $44.95, ‘‘The Norton Shakespeare: Based on the Oxford Edition’’ runs for 3,420 pages, offering introductions, illustrations and notes and three versions(版本) of ‘‘King Lear.’’

Today, movies and videos have made the plays even more accessible. Last year, ‘‘William Shakespeare’s Romeo and Juliet’’ was No. 1 at the box office when it opened, and it grossed nearly $50 million. In New York in January, crowds lined up in the freezing cold to see Kenneth Branagh’s four-hour ‘‘Hamlet.’’ The students select a scene and then have a violent discussion about it.’’ Influenced by films, professors are increasingly teaching students by having them perform the plays.

Why people from 18 countries came to Washington this year?

A. To celebrate Shakespeare’s 433d birth day only.

B. To watch some plays by Shakespeare as planned.

C. To celebrate Shakespeare’s birthday and study his works.

D. To discuss how to teach students using Shakespeare’s plays.

What does the underlined word “ field” in the fourth paragraph refer to?

A. Washington D.C.                              B. Shakespeare Association.

C. The birthday anniversary.                  D. The Shakespeare business.

Which of the many plays by Shakespeare was most popular the year before?

A. King Lear.                                            B. Hamlet.

C. Macbeth.                                              D. Romeo and Juliet.

What does the author want to prove by using so many examples about Shakespeare?

A. More and more people are becoming interested in Shakespeare.

B. Shakespeare business is being run well in America nowadays.

C. Plays by Shakespeare can be used at school for more studies.

D. Shakespeare belongs not only to Britain but also to the USA.

Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.

Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.

The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.

Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.

When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.

As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.

1.Doherty and his team of scientists did an experiment to evaluate       .

A.children’s and adults’ eye-sight

B.people’s ability to see accurately

C.children’s and adults’ brains

D.the influence of people’s age

2.When asked to find the larger circle,       .

A.children at 6 got it wrong 79 % of the time with no gray ones around

B.only adults over 18 got it right 95% of the time with gray ones around

C.children at 4 got it right about 79 % of the time with gray ones around

D.adults got it right most of the time with gray ones around

3.According to the passage, we can know that       .

A.a smaller orange circle appears bigger on a white background

B.an orange circle appears bigger than a gray one of the same size

C.a circle surrounded by other circles looks bigger than its real size

D.a circle surrounded by bigger ones looks smaller than its real size

4.Visual context may work when children get older than       .

A.4

B.6

C.10

D.18

5.Why are younger children not fooled?

A.Because they are smarter than older children and adults.

B.Because older people are influenced by their experience.

C.Because people’s eyes become weaker as they grow older.

D.Because their brain can hardly notice related things together.

An astronomer is making a case for launching pop singer Justin Bieber into suborbital(亚轨道的)space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager — he would come back down to Earth eventually, after all — but rather to help jump-start the emerging suborbital spaceflight industry.

It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. “If there’s more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good.”

Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport.

None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z.

Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists — but Shostak is thinking about ways to make it grow.

A celebrity launch isn't Shostak’s only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling(充满)with cameras both inside and out, to give the public dramatic views of every mission.

Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry’s success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.

1.Why may Justin Bieber be sent into suborbital space?

A.To show his bravery and make him a role model for teenagers.

B.To arouse the American public’s interest.

C.To help reform the spaceflight industry.

D.To film an advertisement about space.

2.What can we learn about suborbital spaceflight?

A.A trip will return to Earth before finishing a lap.

B.The whole trip will leave passengers weightless.

C.Each trip can take 500 passengers.

D.The trip will be too expensive even for celebrities.

3.What can we infer from the text?

A.SpaceShipTwo will be the first to fly.

B.Famous people will be the main passengers in the future.

C.The space trip is still in preparation.

D.Every space trip will be made into a film.

4.The last paragraph suggests that _________.

A.space is too mysterious to explore

B.the suborbital market is promising

C.the spaceflight industry is more successful than people think

D.developing the industry is risky

5.What is the main purpose of the text?

A.To predict a change in the space market.
