One of the most widely accepted, commonly repeated assumptions (假设) in our culture is that if you exercise, you will lose weight. I exercise all the time, but I still have gut fat that hangs over my belt when I sit. Why isn’t all the exercise getting rid of it?
It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study — the Minnesota Heart Survey — found, more of us at least say we exercise regularly.
And yet obesity (肥胖) figures have risen sharply in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?
The popular belief that exercise is essential for weight control is actually fairly new. As recently as the 1960s, doctors routinely advised against too much exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases — those of the heart in particular. They less often develop cancer and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly over-evaluated.
“In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, exercise researcher at Louisiana State University. Many recent studies have found that exercise isn’t as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or, for that matter, from magazines like this one.
The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can make one hungry. That causes us to eat more, which in turn can negate (使无效) the weight-loss benefits we just gained. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder. From the passage we learn that ____.

Mary and Peter were having a picnic with some friends near a river when Mary noticed an object overhead. "Look!" she shouted to her friends. "That's a spaceship up there and it's going to land here."
Frightened by the strange silver-colored spaceship, most of the young peopl
e got in their cars and drove away quickly. Peter was fond of Mary and always stayed close to her. They, more curious than frightened, watched the spaceship land and saw a door open. When nobody 
came out, they went to the spaceship and entered inside. Peter followed Mary into the spaceship and did not hear the door closed behind him. The temperature fell rapidly and the two young people lost consciousness.
When they woke up, they were surprised to see that they were back by the river again. The spaceship had gone. Their car was nearby.
"What happened?" asked Mary.
Peter scratched (抓k.&s~5*u) his head, saying slowly, "Don't ask me. Perhaps we had a dream. Did you...Did you see a spaceship?"
"Yes," said Mary. "And we both went into it. Then..." she looked at her wrist. "That's funny. My watch has stopped. Oh, well, come on. It's time to go home."
Driving about fifty meters, they found their way blocked by a thick wall made of something like glass. They got out of the car and tried to find their way round the wall but discovered that they were inside a circular wall. It was like a mirror and prevented them from seeing through it.
On the other side of the wall, strange creatures walked past slowly. A few stopped to stare through the wall and read a new notice which, translated into English, said: "New arrivals at the zoo: a pair of Earthlings in their natural surroundings with their mobile house."

There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives (蜂窝). So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn (爆米花) .
Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!
If your friend cannot sto
p talking about something because she thinks it is important, you might say she has a bee in her bonnet (女帽). If someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.
Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction (生殖) say this is talking about the birds and bees.
Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still. If you make a beeline for something, you ______ .
| A．are as busy as a bee | B．go quickly and directly towards it |
| C．always go to the same place | D．buy something at a certain place |
The underlined expression “ it is the bee’s knees” _______ .

Liu Xiang, a 21-year-old Chinese athlete, got the gold medal of the fascinating men’s 110m hurdles before a crowd of 70,000 at the Olympic Stadium in the 28th Olympics in Athens late Friday local time. He clocked an excellent 12.91 seconds to equal the world record set by Britain’s Collin Jackson in 1993.
It is the first gold Chinese men’s athlete has ever won from the track and field in the Olympics history. China has won over 100 gold medals from the summer Olympic Games since 1984 but its male athletes only got one medal from Olympics’ most popular sport, the track and field.
The Shanghai native, with his father a truck driver and mother an out-of-work housewife, loved sports when he was very little. Liu was selected to the Junior Sports School of Putuo District of Shanghai to practice jumping as a fourth grader in the primary school. But after a bone test showing that he will not be able to become a tall man, Liu was asked to give up sports one year later, although he had won the national champion at that level.
In 1998 when he attracted coach Sun Haiping’s attention as a 15-year-old jumper, Sun was a well-known hurdle coach and he believed a star was born at the first sight of Liu. He visited Liu’s parents several times and finally persuaded them to let Liu transfer to the 110m hurdles.
After only three years, Liu launched his career in style in the IAAF Grand Prix in Lausanne in 2001 by breaking the world youth and Asian record with a time of 13.12.
But the first warning he sent to the world was his bronze-winning feat（战绩）at the world indoor championships in Birmingham, England, last year.
In 2004, Liu won the silver in the world indoor championships in Budapest in March. Two months later, he proved the winner in a race against American great Allen Johnson in the IAAF Grand Prix in Osaka, Japan, where he clocked a new Asian record and world’s season best time of 13.06 seconds.
He went on to win two Johnson-absent races in Lille, France, on June 26 and Zagreb, Croatia, three days later. He put up an exciting show at the Golden Gala meet in Rome on July 3, when he and Johnson clocked an identical time of 13.11. Race officials had to examine a photo finish to declare Johnson the winner. Liu did a better job of clearing the hurdles than Johnson, but Johnson’s stronger start ended up making the difference. The race boosted（提高） Liu’s optimism(乐观) for the Olympics, although Johnson bettered his season best time by 0.01 second in Lausanne, Switzerland, on July 6.
The world has put the Olympics a Johnson-Liu duel but surprisingly Johnson crashed out of the Games after falling at the ninth hurdle at round 2. Johnson’s early exit paved the way for Liu’s win. He finally took the gold medal and put a Chinese man’s name on the record book.
(chinadaily.com.cn /Xinhua) Updated:2004-08-28 02:57According to Paragraph One, which of the following is TRUE?
| A．Liu Xiang is the fastest of the mentioned athletes. |
| B．Liu Xiang has set a new world record in the event of the men’s 110m hurdles. |
| C．Both Liu Xiang and Jackson got a gold medal at the Athens Olympics. |

| C．Terrence Trammell got a gold medal from the men’s hurdles at the Sydney Olympics |
| D．Zhu Jianhua got a bronze medal from the men’s hurdles in the 1984 Los Angeles Games |

| B．Liu Xiang set a new world youth record when he was 17 years old |
| C．Liu Xiang has succeeded because of his coach Sun |
