While watching the Olympics the other night, I came across an unbelievable sight
题型：不详难度：来源：
The event was swimming and started with only three men on the blocks．For one reason or another, two of them false started, so they were disqualified．That left only one to complete．It would have been difficult enough, not having anyone to race against, even though the time on the clock is important．
I watched the man dive off the block and knew right away that something was wrong．I"m not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality．When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle．The crowd started to laugh．Clearly this man was not a medal competitor．
I listened to the crowd begin to laugh at this poor man who was clearly having a hard time．Finally he made his turn to start back．It was pitiful．He made a few desperate strokes and you could tell he was worn out．
But in those few awful strokes, the crowd had changed．
No longer were they laughing, but beginning to cheer．Some even began to stand and shout “Come on, you can do it!” and he did．
A clear minute past the average swimmer, this young man finally finished his race．The crowd went wild．You would have thought that he had won the gold, and he should have．Even though he was recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors．
Just a short year ago, he had never even swum, let alone race．His country had been invited to Sydney．
In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog．

While such vigilant(警觉的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.
It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).
A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.
小题1:Why do doctors recommend routine cancer screening for elderly people?
| A．It is believed to contribute to long life. |
| B．It is part of their health care package. |
| C．The elderly are more sensitive about their health. |
| D．The elderly are in greater danger of tumor growth. |

| B．It helps increase their life expectancy. |
| C．They are doubtful about necessity. |
| D．They think it does more than good. |
| A．It applies to women over 50. |
| B．It is a must for adult women. |
| C．It is optional for young women. |
| D．It doesn’t apply to women over 74. |
| A．They want to protect themselves against medical disputes. |
| B．They want to take advantage of the medical care system. |
| C．They want data for medical research. |
| D．They want their patients to suffer less. |
| A．The more, the better. |
| B．Prevention is better than cure. |

Wycherley from the University of South" Australia in Adelaide, the lead author on the study says it’s possible that the body may spend more energy and bum more calories while dealing with protein, compared to carbohydrates. Another explanation for the link his team observed is that eating protein helps preserve muscle mass and muscle mass bums more calories, even when the body is resting, than other types of mass. He says people in the studies tend to get protein from a variety of animal and vegetable sources. Vegetable sources of protein include beans.
It is not obvious why a higher protein-to-carbohydrate ratio might help people lose more pounds——and one obesity researcher not involved in the new analysis questioned whether the trials were strong enough to make that conclusion. “The studies are generally far too short to tell effect,” Dr. James Levine from the Mayo Clinic in Scottsdale, Arizona, told Reuters Health in an e-mail. But given the limitations of the present evidence, Levine said, “It makes no real difference which of the weight-loss ways one chooses.”
小题1:According to Wycherley’s analysis, dieters should take in more ______.
| A．fat | B．carbohydrates | C．protein | D．calories |
| A．It bums more calories to deal with carbohydrates. |
| B．Protein helps keep muscle mass which bums calories. |
| C．Vegetables contain more protein than animals. |
| D．No more calories are burned while the body is resting. |
| A．Doubtful. | B．Supportive. | C．Curious. | D．Agreeable. |
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste. and transport. But things had to be different in London because seven years ago it bid for the Olympics through the concept of “a One Planet Olympics”.
What is most impressive is that London used the construction of the Olympic Park as an opportunity to clean up polluted areas — 2 million tons of contaminated (被污染的) soil were removed and 200 old factory buildings, were torn down, according to sustainablebusiness.com. But that’s not all —. 99 percent of the debris (废瓦砾) were reused to build the Olympic Park. For example, part of the Olympic Stadium’s roof is made from 2,500 tons of steel tubes recycled from old gas pipelines.
As well as using recycled materials, all venues were built with green building techniques. The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed. Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent, according to sustainablebusiness.com.
The effort that London made to deal with waste also deserves praise. Water used for drinking and watering plants was from collected rainwater or recycled wastewater. In this way. about 30-40 percent less water was used in total. Waste food packages were either recycled or processed and turned into renewable energy.
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport. For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions.
The clean anti-doping (反兴奋剂) result also added to the greenness of the Games. The International Olympics Committee (IOC) said that the devices used this time were the most accurate and advanced. Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games.

| B．London has possessed the most advanced techniques to deal with waste. |
| C．Public transport is made good use of in London during the Olympic games. |
| D．The anti-doping result in the London Olympics turned out to be dissatisfactory. |
小题5:What is the best title of the passage?

| B．How to use recycled materials |
| C．London’s green games |
| D．London’s public transport |
Living in an exciting social environment was found to reduce fat in mice"s belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body"s nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team"s findings appear in the journal Cell Metabolism, said, "I"m still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It"s not just a sedentary(久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said，"Loneliness is a potential factor for cancer and death; it"s equal to cigarette smoking to a certain extent. Social activities are very vital.
小题1:What information can we get from the first two paragraphs?
| A．Brown fat stores calories and makes us fatter |
| B．It doesn"t take long to turn white fat into brown. |
| C．Social excitement helps gain more weight |
| D．Brown fat can burn energy to produce heat. |
| A．Levels of brown fat can be increased by socializing. |
| B．The mice lacking social life lose more weight. |
| C．The research findings haven"t been published so far. |
| D．Dr Matthew During wasn"t convinced of the result. |
| A．the fat in mice"s belly was reduced because of the relaxing environment |
| B．a sedentary lifestyle and high calories foods influence people"s social life |
| C．surfing the Internet may influence people"s face-to-face communication |
| D．cancer and death are mainly caused for lack of social life |
| A．Brown fat is beneficial to people"s health. |
| B．Socializing is unnecessarily important in people"s daily life. |
| C．White fat can be changed into brown fat. |
| D．Socializing contributes to people"s losing weight. |
In 1997, Avian Influenza caused widespread panic in Hong Kong．It is said that the Avian Influenza originated from Shenzhen. Some Hong Kong people blamed the chicken farm staff on the mainland for the outbreak. The staff was accused of not thoroughly checking the health condition of the chicks under their care. It resulted in Hong Kong people"s anger towards chicken farm staff in Shenzhen, whose supposed negligence(疏忽)contributed to the later spread of Avian Influenza in Hong Kong．
Worse still, in Germany, people have been warned not to eat cucumbers until tests can identify the source of a deadly E. coli outbreak. The scare has spread across Europe, with 16 people so far having been killed．In many people"s minds, European countries have the strictest standards and checking procedures on their food safety. But the E. coli cucumber incident brought home the reality that it was not an effective defense against such an outbreak．
These diverse food safety issues from various parts of the world are enough evidence that food safety problem is not endemic in China. In fact, food safety is not even directly related to the development level of a place, thanks, no doubt, to the connectivity of our age. If we do not maintain our vigilance(警惕), people"s confidence in food safety can be destroyed instantly—even in a developed country
小题1:Which of the following is true according to the passage?
| A．Nowadays, food safety incidents spread inside one country |
| B．In 1997, Avian Influenza caused great fear in Hong Kong |
| C．16 Germans died of deadly E. coli after eating cucumbers |
| D．Food safety is only related to the developing countries |
| A．serious | B．common | C．urgent | D．unique |
| A．food safety problems spread from one country to another |
| B．the staff of a Shenzhen chicken farm caught Avian Influenza |
| C．the strictest standards protected European people from getting E. coli |
| D．China is a country where food safety problem is related to people"s age |
| A．Food Safety Problem Is a Global Issue |
| B．Cucumbers Are Popular in European Countries |
| C．Avian Influenza Originated from Shenzhen |
| D．Food Safety Issues Are Various from Country to Country |
