ty affected winter weather patterns．However, the researchers were eager to stress that their findings did not suggest that the region was about to fall suddenly into a "little ice age"．The findings appear in the journal Environmental Research Letters．"We could get to the point where one-in-seven winters are very cold, as we had at the start of last winter and all through the winter before last," said co-author Mike Lockwood, professor of space environment physics at the University of Reading．
Using the Central England Temperature （CET） record, the world"s longest instrumental data series that dates back to 1659, the team said that in general temperatures during recent winters had been obviously lower than the longer-term temperatures．"The mean CET for December, January and February for the recent relatively cold winters of 2008 ~ 2009 and 2009~2010 were 3．50℃ and 2．53℃ respectively," they wrote．
"However, the mean value for the previous 20 winters had been 5．04℃．The series of lower winter temperatures in the UK during the last three years had raised questions about the probability of more similar, or even colder, winters occurring in the future．"Last year．Professor Lockwood and colleagues published a paper that found a link between fewer sunspots and atmospheric conditio
ns that "blocked" warm westerly winds reaching Europe during winter months, opening the way for cold easterly winds from the Arctic and Russia to sweep across the region．Professor Lockwood, while acknowledging that there were a range of possible meteorological factors （气象因素） that could influence blocking events, said the latest study moved things forward by showing that there was "impro
vement in the predictive skill" when solar activity was taken into consideration．小题1:We can know from the second paragraph that _____．
| A．research shows that Britain will soon fall into an ice age |
| B．Mike Lockwood"s research focuses on space environment physics |
| C．it was quite cold in Britain over the entire winter last year |
| D．so far one-in-seven winters have been very cold in Britain |
| A．average | B．stable | C．ungenerous | D．changeable |
| A．It was sunspots that blocked warm westerly winds reaching Europe． |
| B．Meteorological factors hardly have any influence on blocking events． |
| C．The latest study done by Professor Lockwood was of little practical value． |
| D．Considering solar activity or not affects the accuracy of weather forecasting． |
| A．Another big danger approaching the UK |
| B．Research finds out solar activity is to blame for the cold |
| C．UK faces more cold winters due to weaker solar activity |
| D．Changes in weather patterns should be responsible for low solar activity |

Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the connection between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. She said, "So this finding from our new study was quite a surprise. We didn"t really have any expectation of which direction it could go into."
To sort out the confusion, Hashibe and her assistants used statistical (统计学 ) techniques to, in effect, make one big study out of the earlier smaller studies. She explained, "Thanks to the earlier studies, we have a lot more power than earlier studies that looked at this. And we included 4,000 cancer patients who have cancer of the mouth and throat. And then 9,000 controls, people who do not have cancer. "
Those studies--in Europe and the United States--found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat. "We saw a protective effect for drinking more than 4 cups of coffee per day," Hashibe said. "This was the 40 percent decrease in risk. We did not see the same effect for drinking three cups or less per day."
Mia Hashibe said there was a weak connection between cancer risk and drinking coffee without caffeine. And she and her assistants found no proof that drinking tea provided the same protection as drinking Coffee. Their research is published in the journal Cancer Epidemiology, Biomarkers & Prevention.
Hashibe says it is not clear how coffee might protect drinkers from certain cancers. "There are a few chemicals that are known to be antioxidants （抗氧化物）in coffee. So we are thinking perhaps they are playing some sort of protective role against several cancers."

Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their relaxation.
Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.
The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.
A mountain climber continues to improve in skill year after year. A skier (滑雪者) is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment.
小题1: The main difference between a sport and a game lies in .
| A．activity | B．uniform | C．rules | D．skills |
| A．mountaineers depend on each other while climbing |
| B．teams compete against each other |
| C．it is an Olympic event |
| D．there are five climbers on each team |
| A．How to Climb High Mountains | B．Mountain Climbers |
| C．Challenging Sports Activities | D．Mountaineering |
List all the reasons why you want to quit. Every night before going to bed, repeat one of the reasons 10 times.
Decide positively that you want to quit. Try to avoid negative thoughts about how difficult it might be. Develop strong personal reasons as well as your health and responsibility to others. For example, think of all the time you waste taking cigarette breaks, rushing out to buy a pack, hunting a light, etc. Set a date for quitting --- perhaps a special day like your birthday, a holiday. If you smoke heavily at work, quit during your vacation. Make the date seriously, and don"t let anything change it. Begin to condition yourself physically; start a modest (适当的) exercise; drink more water; get plenty of rest.
Immediately after quitting...
The first few days after you quit, spend as much free time as possible in places where smoking is prohibited, e.g. libraries, museums, theatres, department stores, etc.

So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides. Organic farmers rely on many methods — such as crop rotation (农作物的轮作) and the use of resistant（有抵抗力的） varieties, because
they are necessary for organic farmers to compensate for the shortage of man-made chemicals.Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture publicized that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims （宣称） made for organic farming is always true”.
However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.
小题1:The first paragraph mainly tells us _____.
| A．organic farming has been performed only in Europe over the past 10 years |
| B．governments of European countries have cared less about organic farming |
| C．organic farming is far from being as popular as expected |
| D．European countries need organic food more than the other countries in the world |
| A．argue for | B．care for | C．struggle for | D．pay for |
A．It refers to farming with na tural materials, instead of chemical fertilizers. |
| B．It refers to farming with chemical fertilizers rather than natural fertilizers. |
| C．It refers to farming with soil rather than any other thing. |
D．It refers to growing crops with man-made f ertilizers and pesticides. |
| A．organic farming is safer than traditional farming for the environment |
| B．the idea that organic farming is safer has not been proven by science |
| C．organic farming is accepted by the UK’s House of Commons committee |
| D．organic farming is preferred to traditional farming |
| A．The UK’s agriculture minister is an organic farmer. |
| B．Organic farming is popular with young people. |
| C．Farmers make use of many different kinds of methods to improve the organic sales system. |
| D．Ninety-three percent of British shoppers don’t buy organic products. |
Experts in childhood nutrition aren’t surprised by an investigation this summer that shows 50％of parents who have overweight children don’t realize their children Weigh too much．Many parents deny their children’s weight because they don’t want to have to change their own eating and exercise habits，says Keith Ayoob, a doctor who works with overweight children and their families in New York City．
Parents frequently ask him whether their children have a thyroid(甲状腺) problem, but that’s rarely the case．“1t’s usually a dietary(有关饮食的) and lifestyle issue．It’s very difficult for parents to deal with their own food issues，”Ayoob says．An estimated 25 million children in the USA are overweight, which puts them at risk of developing diabetes(糖尿病), high blood Pressure and other health problems．A Consumer Reports magazine investigation released on July 25，2009 of 3．048 parents who have children aged 5 to 17 found that 91% say childhood obesity (肥胖) is a problem in the USA．
Only 36％of the parents
with heavy children say their family doctors have suggested their children lose weight；the other 64％say the doctors didn’t mention it．“Many parents simply don’t realize their children are overweight．”says Keith Ayoob．“The doctors never told them．Other kids in the class look like their children．and their kids seem pretty healthy
．”he says．He has parents go to the calculator on the Centers for Disease Control and Prevention website to figure out whether their children are too heavy．
