Ellen Parker was worried about her health. She could not walk very quickly and it was difficult for her to climb stairs. She was soon out of breath.
“I suppose I had better go to the doctor.” she thought.
She went to the doctor and told him her problem.
“I’m not at all surprised.” he said, “I know what your problem is.”
He examined her and then gave her some advice.
“If you don’t do what I say, Mrs Parker,” he said, “You will have a heart attack (心脏病发作). It could kill you.”
Ellen was very worried as she left the doctor’s. She knew that she had to take his advice but that it would not be easy and it would take time.
The next day she went shopping. The first shop she went into was a butcher shop (肉铺).
“I’d like ten pounds of steak (牛排), please.” she said.
“Certainly, madam.” the butcher replied and went into the cold room and found a large piece of steak. He brought the huge piece of meat back into the shop and placed it on the scale (称).
“That’s just ten pounds.” he said.
“That’s big enough.” Mrs Parker said.
The butcher worked out the price.
“At S｜4.99 a pound that will be S｜49.90, please. Would you like me to cut it up into smaller pieces for you?”
“Oh, I don’t want to buy the meat.” Mrs Parker said.
“If you don’t want to buy it,” the butcher replied angrily, “Why did you ask me to get it for you?”
“My doctor told me that I am too heavy and have to lose ten pounds. I wanted to see what ten pounds of meat looked like.”Why did Ellen Parker visit the doctor?

Running like the wind, roaring (咆哮) like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China.
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.
The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950's, there were over 4000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species.
Sixtysix of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves.
“Breeding has damaged the quality of the species”， said Pei Enle, deputy director of the Shanghai Zoo.
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.
“South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”， said Lu Jun, office director of the National Wildlife Research and Development Center. “We tried in Fujian Province, but it was not successful as there was not a complete ecochain(生物链) and there was a lack of space.”
The tigers should return to China in 2007 when the reservations in Fujian are ready.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
| A．Because it has lost its natural instincts. |
| B．Because there is not a complete ecochain. |
| C．Because there is no space for it. |
| D．Because uncontrolled hunting has destroyed its natural living conditions. |
How is the programme of sending several tigers to South Africa getting on?
| A．Its effect still remains to be seen. |
| B．Two tigers can already compete with their wild cousins. |
| C．Some of the tigers are already on the road to recovering their natural skills. |
| D．The tigers should be able to recover their instincts completely by 2007. |
By saying “but they are nothing like their wild cousins”， the writer means that________.
| A．they are no longer feared by other wild animals |
| B．they don't know how to hunt or kill |
| C．a complete change has resulted in the species because of breeding |
| D．to reintroduce them into the wild has become an urgent task |
What is the purpose of sending young tigers to South Africa?
| A．To help the tigers recover their ability to live in the wild. |
| B．To provide them with a better environment. |
| C．To get the tigers to go on a tour. |
| D．To find a complete ecochain for them. |
Which one is NOT the reason for South Africa being chosen as the training place?
| A．Because the tigers can hunt wild animals by themselves at the African base. |
| B．Because South Africans are skilled at dealing with the tigers. |
| C．Because there is a complete ecochain and enough space there. |
| D．Because the country has good natural conditions for the tigers to learn in. |
Since the 1970s, scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.BCI is a technology that can ________.
| A．help to update computer systems |
| B．link the human brain with computers |
| C．help the disabled to recover |

How did Tavella operate the wheelchair in the laboratory?
| A．By controlling his muscles. |
| B．By talking to the machine. |
| C．By moving his hand. |
| D．By using his mind. |
Which of the following shows the path of the signals described in Paragraph 5?
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |

Winter is a very special time in Northern Norway. Winter also means skiing, and Narvik can offer some of the best skiing in Norway. The view and light change frequently and no two days are the same. For many people, the northern lights are an unforgettable sight, and in Narvik the sky is especially clear and great for watching at night.
The tourist season lasts from February to April, although May can be fascinating too, often with fantastic dry snow and an unbelievable light lasting well into the evening.
Ski hire
It is possible for adults and children to hire skiing equipment such as snowboards. All equipment is prepared for us. If you would like to book your equipment, please email Narvikfjellet.
Cross-country skiing
There are 12 kilometers of cross country ski run in Narvik. You need to bring your own skis as there is no cross-country hire. However, equipment can be bought at local sports shops in and around Narvik.
Off-piste skiing（非场地滑雪）
In order to explore Narvik’s off-piste opportunities you need to know the dangers when choosing routes. It is suggested that you bring necessary equipment such as a shovel（雪铲）and a GPS locator. Ask Narvikfjellet for an experienced guide. With a guide you can explore Narvik’s special off-piste areas in a safe manner.
Sometimes it is nice to do something different and not everybody enjoys skiing. Then you can go horse-riding, or visit the local museums.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need.
We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place. The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard. Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place.
Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example. But this is not just about supermarkets. It is about all of us.
We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.The author uses figures in Paragraph 2 to show _______.
| A．the tendency of cutting household waste |
| B．the increase of packaging recycling |
| C．the rapid growth of super markets |
| D．the fact of packaging overuse |
According to the text, recycling ______.
| A．helps control the greenhouse effect |
| B．means burning packaging for energy |
| C．is the solution to gas shortage |
| D．leads to a waste of land |
What can be inferred from Paragraph 4?
| A．Unpackaged products are of bad quality. |
| B．Supermarkets care more about packaging. |
| C．It is improper to judge quality by packaging. |
| D．Other products are better packaged than food. |
What can we learn from the last paragraph?
| A．Fighting wastefulness is difficult. |
| B．Needless material is mostly recycled. |
| C．People like collecting recyclable waste. |
| D．The author is proud of their consumer culture. |
We know that sugary sodas aren’t good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse.
Americans drink far more sodas than people in other countries— as much as 170 liters per person per year. But the impact of this study isn’t limited to the United States. “Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well,” study author Dr Honglei Chen said in a statement.
The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had.
Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch(鸡尾酒), had a 38 percent higher risk than people who didn’t drink sweetened drinks. And all that extra sugar isn’t the actual problem. Researchers say that the artificial sweetener aspartame may be to blame.
The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results “are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes.”
But there’s a bright side for those who can’t live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn’t drink any coffee, according to the study. “Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk,” said Chen.What has the new study of more than 260,000 people found?
| A．Sugary sodas aren’t good for the physical health of old people. |
| B．Americans have a special tooth for sweet foods. |
| C．Sweetened soft-drinks may increase the risk of depression. |
| D．Sweetened soft-drinks have important physical consequences. |
What do we know about the process of the study?
| A．About twenty-six thousand people participated in it. |
| B．The oldest participants were below 80 when the study was over. |
| C．Most of the participants had depression when the study was over. |
| D．The study lasted more than ten years from the beginning to the end. |
It is implied in the passage that ______.
| A．more research is needed to confirm the new findings |
| B．the new findings aren’t consistent with any previous findings |
| C．cutting one’s sodas intake will surely reduce one’s depression |
| D．the new findings won’t have an impact on people’s drinking habits |
What should you drink in order to reduce the risk of depression?
| A．Sodas. | B．Unsweetened coffee. |
| C．Sugary coffee. | D．Fruit punch. |
