When it comes to eating out, we can't help thinking of big meals in the restaurants, which usually contain much more fat and less fibers. Whether it is a business meeting over lunch or a fast food mea 题目和参考答案——青夏教育精英家教网—

Air pollution is damaging 60% of Europe’s prime wildlife sites in meadows, forests and bushes, according to a new report.
A team of EU scientists said nitrogen emissions(氮排放) from cars, factories and farming were threatening biodiversity. It’s the second report this week warning of the on-going risks and threats linked to nitrogen pollution.
Nitrogen in the atmosphere is harmless in its inert(惰性的) state, but the report says reactive forms of nitrogen, largely produced by human activity, can be a menace to the natural world.
Emissions mostly come from vehicle exhausts(排气), factories, artificial fertilizers(肥料) and animal waste from intensive farming. The reactive nitrogen they emit to the air disrupts the environment in two ways: It can make acidic soils too acidic to support their previous mix of species. But primarily, because nitrogen is a fertilizer, it favors wild plants that can maximize the use of nitrogen to help them grow.
In effect, some of the nitrogen spread to fertilize crops is carried in the atmosphere to fertilize weeds, possibly a great distance from where the chemicals were first applied.
The effects of fertilization and acidification favor common aggressive species like grasses, brambles and nettles. They harm more delicate species like mosses(苔藓), and insect-eating sundew plants.
The report said 60% of wildlife sites were now receiving a critical load of reactive nitrogen. The report’s lead author, Dr Kevin Hicks from the University of York’s Stockholm Environment Institute (SEI), told BBC News that England’s Peak District had a definitely low range of species as a result of the reactive nitrogen that fell on the area.
“Nitrogen creates a rather big problem that seems to me to have been given too little attention,” he said. “Governments are responsible for protecting areas like this, but they are clearly failing.”
He said more research was needed to understand the knock-on effects for creatures from the changes in vegetation accidentally caused by emissions from cars, industry and farms.
At the conference, the representatives agreed “The Edinburgh Declaration on Reactive Nitrogen”. The document highlights the importance of reducing reactive nitrogen emissions to the environment, adding that the benefits of reducing nitrogen outweigh the costs of taking action.
小题1:The underlined word “menace” is used to express that the reactive nitrogen, largely produced by human activity can be ___________.

A．Keeping Away From Nitrogen Emissions	B．Stopping Nitrogen Emissions
C．Air Pollution Damaging Europe’s Wildlife	D．Saving Europe’s Wildlife

Shopping is not as simple as you may think! There are all sorts of tricks each time we reach out for that particular brand（品牌）of product on the shelf.
Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged（包装）in greens, yellows or browns because we think of these as healthy colours. Ice cream packets（包装） are often blue and expensive goods, like chocolates, are gold or silver.
When some kind of pain-killer （止痛药） was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package — blue because we think of it as safe, and white as calm.
The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.
It is believed that the better-known companies spend, on average, 70 percent of the total cost of the product itself on packaging!
The most successful producers know that it’s not enough to have a good product. The founder of Pears Soap, who for 25 year has used pretty little girls to promote（促销）their goods, came to the conclusion: “Any fool can make soap, but it takes a genius（天才） to sell it.”

A．Choice of Good Products.	B．Disadvantages of Products.
C．Effect of Packaging on Shopping.	D．Brand Name and Shopping Tricks.

Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help.
First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling (肿大) and pain may occur. Unless the burn involves large portions of the body, it can be treated at home.
Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters (水泡) develop. Severe pain and swelling also occur. Second-degree burns require medical treatment.
Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention.
Follow these steps when treating minor burns at home:
1) If the skin is not broken, run cool water over the burn for several minutes.
2) Cover the burn with a sterile (消过毒的) bandage or clean cloth.
3) Take aspirin to relieve any swelling or pain.
Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps:
1) Remove the person from the source of the burn (fire, electrical current, etc.).
2) If the person is not breathing, begin mouth-to-mouth resuscitation (人工呼吸) immediately.
3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it.
4) Cover the burned area with a cool, moist, sterile banda

ge or clean cloth. Do not place any creams, ointments (药膏) or ice on the burned area or break blisters.
5) Monitor the patient for signs of shock, and treat accordingly.
小题1:The underlined sentence in the first paragraph probably means “______”.
A. They can be dangerous if you don’t treat them seriously
Ｂ. They range from slight burns to deadly ones
C. They seldom cause deaths even if not treated properly
D. They usually cause deaths if not treated properly

Alaskan black bears hibernate for up to seven months a year, during which time they do not eat or drink, before waking up in virtually the same physical state they fell asleep in．
Now experts hope to develop methods of putting humans into a similar state which could help astronauts survive long missions and lead to new ways of treating severely ill patients．
While many studies have examined hibernation in mice and hedgehogs, little research has been done into the same condition in larger mammals such as bears．
But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the animals' body temperature, heart rate and muscle movements while they slept.
The research results showed that during a five-month hibernation the bears’ body temeratures varied between 30℃ and 36℃ in cycles that lasted between two and seven days—a pattern that was previously unknown in hibernating animals.
The research project leader said, "If our research could help by showing how to reduce metabolic(新陈代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply need to know how to turn things on and off to take advantage of the different levels of hibernation."
Craig Heller, of Stanford University, who contributed to the study, added: "There has always been a thought that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower metabolism or a state of hibernation. That's almost science fiction but you can see the logical basis."
小题1:We know from the text that .

D．scientists have already take advantage of the different levels of hibernation in space missions

In 2006, a large number of new Internet sites became popular around the world. Some of these are for communication, others for entertainment.
The blog is one form of communication that increased in popularity. Through these personal websites, people can share their lives, ideas and opinions on the Internet. People of all ages have their own blogs. For young people, they are a way to show their writing and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas with other teachers’, as well as experiences and concerns about their work.
YouTube is another Internet site that became more popular last year. This website lets anyone create, share and watch short videos. These include videos of people singing or dancing, or animals doing funny things. Three young men created YouTube almost two years ago as a personal video sharing service. They recently sold it to Google for more than one and a half billion dollars.
Games and entertainment also became a l

arger part of the Internet last year. One Internet social site is called Second Life. It is an online world in which computer u

sers create a new self and live a different life. They get married, build homes, operate businesses, buy and sell goods, work, play and attend school.
People also take part in fantasy sports leagues with the help of the Internet. A fantasy sport is a game in which each member of a group acts as the owner of a team. Each owner creates a team of real-life professional players to compete against other teams in the league. More than fifteen million American adults play fantasy sports. The industry earns more than one billion dollars each year from publications, memberships and other costs.

D．Fantasy sports, a game in which each member of a group acts as the owner of a team, is very popular around the world.

Members of the working class have blue-collar jobs. They are construction workers, truck drivers, mechanican, steel workers, electricians, and the like. What makes this class differ from the lower class is, first, longer periods of employment—and therefore, more fixed incomes—and , second, employment in skilled or semi-skilled occupations, not unskilled ones. Although unemployment hits all levels of the American economy, including those of skilled and semi-skilled workers, it is most common at the bottom of the class structure and increasingly less common at each level upward. They consider themselves to be respectable and hard-working and they look down upon members of the “low” class, whom they often consider to be lazy, dishonest, and too ready to exploit public assistance.
Most people in the working class have at least high school education. Many have some experience of college(especially community college), though few are college graduates. Unionization has helped the working class, but a rapidly changing economy and frequent periods of high unemployment make it difficult for most of its members to be able to increase their savings greatly. Purchasing a house for people in this class is extremely difficult, although a certain percentage may receive houses from their parents. (Home-owning rises with social class.)
A greater number of the members of the working class take relatively little satisfaction in their jobs, because much of their work is ordinary and boring. As a result, many seek their main satisfaction in recreational activities. Many members of this class would like to earn enough money to leave their jobs and start their own businesses, though few make it. Many place their expectations on their children, hoping that they at least will rise in the ladder of success.
小题1: Which of the following is true about the working class?

A．They are often offered jobs with high incomes.

小题3: Most people in the working class ________.

A．have at least some experience of college

B．receive houses from their parents

C．buy houses by themselves

D．have difficulty increasing their savings greatly

小题4: Many members from the working class are not satisfied with their jobs because _____.

A．they are not interested in their jobs.

B．they could not earn much money

C．they are not their own bosses

D．they could not rise in the ladder of success

Our bodies are wonderfully skillful at keeping balance．When the temperature jumps, we sweat to cool down．When our blood pressure falls, our hearts can do something．As it turns out, though, our natural state is always changing．Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons．And their insights （洞察力） are getting new ways for keeping away such common killers as heart disease and cancer．Only one doctor in 20 has a good knowledge of the scientific use of time in medicine．But according to a new American Medical Association, three out of four are eager to change that．“The field is exploding,” says Michael Smolensky．“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more．”
In medical school, most doctors learn that people with chronic conditions should take their medicine regularly．“It’s a terrible way to treat disease,” says Dr Richard Martin．For example, asthmatics （气喘患者） are most likely to suffer during the night．Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler （吸入器） four times a day or taking a pill each morning and evening．In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator （支气管扩张剂） can be as safe as several small doses, and better for preventing nighttime attacks．
If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease．Heart attacks are twice as common at 9 a．m．as at 11 p．m．Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day．“Doctors know that,” says Dr．Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it．” Most blood - pressure drugs provide 18 to 20 hours of relief （减缓）．But because they’re taken in the morning, they're least effective when most needed．“You take your pill at 7 and it's working by 9,” says Dr．William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection．” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night．
小题1:Researchers are finding that _________ ．

A．heart disease and cancer are the most common killers of human beings

B．only blood pressure and brain function are decided by cycles of sun, moon and seasons

C．the functions of human bodies have much to do with nature

小题2:According to the author, it is best for asthmatics to

take their medicine _________ ．

A．at certain time

B．each morning and evening

C．when the disease occurs

D．at midafternoon

B．Doctors in the U．S．used to be thirsty to know more about the new medical field．
C．The researchers' insights are providing new methods to prevent common killers．
D．The correct use of time in medicine attracts more attention in medical circle in the U．S．A．
小题4:The suggested title for this passage might be _________．

A．Medicine Is Everything	B．Treatment Is Everything
C．Timing Is Everything	D．Prevention Is Everything

Windsurfing is a sport that combines sailing and surfing．In 1948，twenty-year-old Newman Darby first

thought of using a handheld sail to contro1 a small boat．Darby did not apply for a patent(专利)for his design at first．However，he is recognized as the inventor of the first sailboard．
Californians Jim Drake，a sailor and engineer，and Hoyle Schweitzer，a surfer and skier received the patent for a sailboard．They called their design a windsurfer．The early windsurfer boards measured 3．5 meters long and weighed 60 pounds．Later in the l980s，Newman Darby did apply for and receive a design patent for a one—person sailboat．
In the late l940s，Newman Darby found he could control a 3-meter-long sailboat and make turns even without a rudder(舵)．In l964 he designed the first universal joint(万向接头)to go along with a flat bottom sailing boat．This sailboard was equipped with a universal joint，a board and a kite—shaped free sail and thus windsurfing was born．
Naomi Darby，Newman’s wife，was the first woman windsurfer and helped her husband build and design the first sailboard．She sailed while standing up，controlling the boat without the use of a rudder．She tilted(倾斜)the sail to change directions．This was something that had never been done before．
Hoyle Schweitzer began producing sailboards in the early 1970s．The sport became very popular in Europe．By the late 1970s，windsurfing fever had Europe firmly in its grasp with one in every three families having a sailboard．
The first windsurfing world championship was held in 1973．Windsurfing first became an Olympic sport for men in l984 and for women in l992．
