Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.

WASHINGTON(Reuters)?People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer (胰腺癌), an unusual but deadly cancer, researchers reported on Monday.
People who drank mostly fruit juice instead of sodas did not have the same risk, the study of 60,000 people in Singapore found.
“Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits,” said Mark Pereira of the University of Minnesota, who led the study.
“The high levels of sugar in soft drinks may be increasing the level of insulin(胰島素) in the body, which we think contributes to pancreatic cancer cell growth,” President said in a statement.
Writing in the journal Cancer Epidemiology, Biomarkers & Prevention, Pereira and his colleagues said they followed 60,524 men and women in the Singapore—Chinese Health Study for 14 years.
Over that time, 140 of the volunteers developed pancreatic cancer. Those who drank two or more sweetened soft drinks a week had an 87 percent higher risk of being among those who got pancreatic cancer.
Pereira said he believed the findings would apply elsewhere.
“Singapore is a wealthy country with excellent healthcare. Favorite pastimes(消遣) are eating and shopping, so the findings should apply to other western countries.” he said.
But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious.
“Although this study found a risk, the finding was based on a relatively small number of cases and it remains unclear whether it was a causal(因果的) connection or not.” Said Mayne, who serves on thee board of the journal, which is published by the American Association for Cancer Research.
Pancreatic cancer is one of the deadliest form of cancer, with 230,000 cases globally. In the United States, 37,680 people are diagnosed with pancreatic cancer in a year and 34, 290 die of it.
【小題1】We can infer from Pereira’s word that_________
| A．the healthcare in Singapore should be greatly improved |
| B．2 soft drinks a day are considered harmful to health |
| C．87 out of 140 volunteers developed pancreatic cancer |
| D．sugar might not be the only cause of pancreatic cancer. |
| A．Satisfied | B．Doubtful | C．Worried | D．Hopeful |
| A．The Deadliest Forms of Cancer |
| B．Drink Fruit Juice Instead of Sodas |
| C．A Study in University of Minnesota |
| D．Sugary Soft Drinks Lead to Cancer |

Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across Americas farmland. It has little to do with the usual challenges, such as flood, rising fuel prices and crop-eating insects. The country's farmers are getting older, and there are fewer people standing in line to take their place. National agricultural census (普查) figures show that the fastest-growing group of farmers is the part over 65. Merrigan is afraid the average age will be even higher when the 2012 statistics are completed.
Merrigan, a former college professor, is making stops at universities across the country in hopes of encouraging more students to think about careers in agriculture. Aside from trying to stop the graying of America's farmers, her work is made tougher by a recent blog posting that put agriculture at No.1 on a list of "useless" college degrees. Top federal agriculture officials are talking about the posting, and it has the attention of agricultural organizations across the country.
“There couldn't be anything that's more incorrect," Merrigan said. "We know that there aren't enough qualified graduates to fill the jobs that are out there in American agriculture.
In addition, a growing world population that some experts predict will require 70% more food production by 2050, she said.
“I truly believe we're at a golden age of agriculture. Global demand is at an all-time record high, and global supplies are at all-time record lows," said Matt Rush, director of the Texas Farm Bureau. "Production costs are going to be valuable enough that younger people are going to have the opportunity to be involved in agriculture”.
The Department of Agriculture has programs aimed at developing more farmers and at increasing interest in locally grown food. The National Young Farmers' Coalition has also been pushing for state and federal policy changes to make it easier for new fermers.
Ryan Best, president of Future Fanners of America, has been living out of a suitcase, traveling the country and visiting with high school students about careers in agriculture. The 21 -year-old Best hopes his message-that this is a new time in agriculture-will motivate the next generation to turn around the statistics.“Never before have we had the innovations (創(chuàng)新）in technology which have led to agriculture in this country being the most efficient it has ever been” he said. “There’s really a place for everybody to fit in”
【小題1】What is the new challenge to American agriculture?
| A．Fewer and older farmers. | B．Higher fuel prices. |
| C．More natural disasters. | D．Lower agricultural output. |
| A．To draw federal agriculture officials' attention |
| B．To select qualified agriculture graduates. |
| C．To clarify a recent blog posting. |
| D．To talk more students into farming careers |
| A．the government will cover production costs |
| B．global food supplies will be even lower |
| C．investment in agriculture will be profitable |
| D．America will increase its food export |
| A．To re-analyze the result of the national census. |
| B．To increase production. |
| C．To bring down the average age of farmers. |
| D．To invest more in agriculture. |

For years we have been told that encouraging a child’s self-respect is important to his or her success in life. But child experts are now learning that too much praise can lead to the opposite effect. Praise-aholic kids who expect it at every turn may become teens who seek the same kind of approval from their friends when asked if they want to go in the backseat of the car.
The implication(含義) of saying “You are the prettiest girl in class,” or talking about the goals she scored but not her overall effort, is that you love her only when she looks the best, scores the highest, achieves the most. And this carries over to the classroom.
Social psychologist Carol Dweck, PHD, tested the effects of over-praise on 400 fifth graders while she was at Columbia University. She found that kids praised for “trying hard” did better on tests and were more likely to take on difficult assignments than those praised for being “smart”.
“Praising attributes(品質(zhì)) or abilities makes a false promise that success will come to you because you have that quality, and it devalues effort, so children are afraid to take on challenges,” says Dweck, now at Stanford University, “They figure they’d better quit while they’re ahead.”
【小題1】The underlined words “Praise-aholic kids” refer to kids who are ______.
| A．tired of being praised | B．worthy of being praised |
| C．very proud of being praised | D．extremely fond of being praised |
| A．better-known | B．better-organized |
| C．more persuasive | D．more interesting |
| A．praise for efforts should be more encouraged |
| B．praise for results works better than praise for efforts |
| C．praising a child’s achievements benefits his or her success in life |
| D．praising a child’s abilities encourages him or her to take on challenges |

Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"I think we are knocking at the door of immortality(永生)," said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that’s a conservative estimate".
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（納米技術(shù)）make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years."
However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology(老齡學(xué)) Center. "At present people who could get to that point are not in good health at all."
【小題1】By saying "we are knocking at the door of immortality", Michael Zey means ________.
| A．they believe that there is no limit of living |
| B．they are sure to find the truth about long living |
| C．they have got some ideas about living forever |
| D．they are able to make people live past the present life span |
| A．people can live from 120 to 180 years |
| B．it is still doubtful how long humans can live |
| C．the human body is designed to last about 120 years |
| D．it is possible for humans to live longer in the future |
| A．a(chǎn) great push |
| B．the idea of living beyond the present life span |
| C．the idea of living from 200 to 300 years |
| D．the conservative estimate |
| A．Living Longer or Not |
| B．Science, Technology and Long Living |
| C．No Limit for Human Life |
| D．Healthy Lifestyle and Long Living |

People diet to look more attractive．Fish diet to avoid being beaten up，thrown out of their social group，and getting eaten as a result．That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists．
The research team have discovered that subordinate(低一等的) fish voluntarily diet to avoid challenging their larger competitors．"In studying gobies we noticed that only the largest two individuals，a male and female，had breeding（繁殖）rights within the group，" explains Marian Wong．"All other group members are nonbreeding females，each being 5-10% smaller than its next largest competitor．We wanted to find out how they maintain this precise size separation．"
The reason for the size difference was easy to see．Once a subordinate fish grows to within 5-10% of the size of its larger competitor，it causes a fight which usually ends in the smaller goby being driven away from the group．More often than not，the evicted fish is then eaten up．
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish．Whether they did so voluntarily，by restraining how much they ate，was not clear．The research team decided to do an experiment．They tried to fatten up some of the subordinate gobies to see what happened．To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights，over having a feast．
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group．Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves，so keeping their competitors small．
While the habits of gobies may seem a little mysterious，Dr．Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical（等級的）societies remain stable．
The research has proved the fact that voluntary dieting is a habit far from exclusive to humans．"As yet，we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature，" the researchers comment．"Data on human dieting suggests that，while humans generally diet to improve health or increase attractiveness，rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal．"
【小題1】When a goby grows to within 5-10% of the size of its larger competitor，it _________．
| A．leaves the group itself | B．has breeding rights |
| C．eats its competitor | D．faces danger |
| A．the fish beaten up | B．the fish driven away |
| C．the fish found out | D．the fish fattened up |
| A．fought over a feast | B．preferred some extra food |
| C．challenged the boss fish | D．went on diet willingly |
| A．Fish dieting and human dieting． | B．Dieting and health． |

Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives.
【小題1】What’s the main idea of the passage?
| A．An auto revolution is on its way. |
| B．Google has developed a driverless car. |
| C．The Carbot has passed its early testing stages. |
| D．Science fiction has turned into reality. |
| A．it uses radar, lasers and video cameras |
| B．it knows speed limits, traffic patterns and road maps |
| C．the computer has a better sense of direction than drivers |
| D．the software responds to emergencies faster than a human driver |
| A．it can drive all by itself |
| B．it can avoid any traffic accident |
| C．it doesn’t pollute the environment |
| D．it is the most fashionable car nowadays |
| A．unfriendly | B．desperate | C．critical | D．optimistic |

Feeling blue about the world? “Cheer up,” says science writer Matt Ridley. “The world has never been a better place to live in, and it will keep on getting better both for humans and for nature.”
Ridley calls himself a rational optimist—rational, because he’s carefully weighed the evidence; optimistic, because that evidence shows human progress to be both unavoidable and good. And this is what he’s set out to prove from a unique point of view in his most recent book, The Rational Optimist . He views mankind as grand enterprise that, on the whole, has done little but progress for 100,000 years. He backs his findings with hard facts gathered through years of research.
Here’s how he explains his views.
1）Shopping fuels invention
It is reported that there are more than ten billion different products for sale in London alone. Even allowing for the many people who still live in poverty, our own generation has access to more nutritious food, more convenient transport, bigger houses, better cars, and, of course, more pounds and dollars than any who lived before us. This will continue as long as we use these things to make other things. The more we specialize and exchange, the better off we’ll be.
2) Brilliant advances
One reason we are richer, healthier, taller, cleverer, longer-lived and freer than ever before is that the four most basic human needs—food, clothing, fuel and shelter—have grown a lot cheaper. Take one example. In 1800 a candle providing one hour’s light cost six hours’ work. In the 1880s the same light from an oil lamp took 15 minutes’ work to pay for. In 1950 it was eight seconds. Today it’s half second.
3) Let’s not kill ourselves for climate change
Mitigating(減輕) climate change could prove just as damaging to human welfare as climate change itself. A child that dies from indoor smoke in a village, where the use of fossil-fuel(化石燃料) electricity is forbidden by well- meaning members of green political movements trying to save the world, is just as great a tragedy as a child that dies in a flood caused by climate change. If climate change proves to be mild, but cutting carbon causes real pain, we may well find that we have stopped a nose-bleed by putting a tourniquet(止血帶) around our necks.
【小題1】What is the theme of Ridley’s most recent book?
| A．Weakness of human nature. |
| B．Concern about climate change. |
| C．Importance of practical thinking. |
| D．Optimism about human progress. |
| A．It encourages the creation of things. |
| B．It results in shortage of goods. |
| C．It demands more fossil fuels. |
| D．It causes a poverty problem. |
| A．oil lamps give off more light than candles |
| B．shortening working time brings about a happier life. |
| C．a(chǎn)dvanced technology helps to produce better candles. |
| D．increased production rate leads to lower cost of goods. |
| A．Cutting carbon is necessary in spite of the huge cost. |
| B．Overreaction to climate change may be dangerous. |
| C．People’s health is closely related to climate change. |
| D．Careless medical treatment may cause great pain. |
| A．Matt Ridley doesn’t think the world is a good place to live in. |
| B．Climate change won’t cause a child’s death. |
| C．Matt Ridley based his unique point of view on his long-term research. |
| D．People will have more freedom for the development of the world. |

Few of us haven’t read Cinderella, the story of a young woman living in poverty who meets the prince of her dreams. Some might not want to admit it, but there is a hidden Cinderella in everyone’s heart—we all wish we could achieve recognition or success after a period of obscurity(默默無聞)or neglect. 
Mary Santiago has that secret dream, too. Her story is featured in Another Cinderella Story, a film set in a US high school.
Mary is shy but loves to dance. Compared with other girls, she is invisible. However, her world changes completely when a famous teenage pop singer, Joey Parker, appears.
Joey is everything the rest of the boys in her class are not—kind, handsome and desirable. Mary and Joey’s paths cross at a ball. They meet and fall in love with each other. But when Mary has to rush back home, she leaves behind her MP3 player, which becomes the only clue Joey has to find the girl of his dreams. Of course, there is a wicked(邪惡的)stepmother, who turns out to be Dominique Blatt and she takes in Mary after her dancer mother dies. Dominique treats Mary like a maid and does everything she can to make sure Mary doesn’t get into the top dance school. Her two daughters are equally determined to stop Joey falling for Mary, even if that means embarrassing her.
The story, though it mostly follows Cinderella, does add a few modern day twists to the classic fairy tale. Refreshingly, the film, unlike many high school films, does not focus on looks, although the actors are all beautiful. There is also a lot less materialism in Another Cinderella Story than in many similar movies.
“The movie takes the fairy tale Cinderella as its jumping off point, ”writes movie critic Amber Wilkinson. “The focus is firmly on following your dream. ”
【小題1】The first paragraph is mainly to .
| A．build interest and lead us to Mary’s secret dream |
| B．remind us why Cinderella is popular all the years |
| C．inform us of the main topic of the whole passage |
| D．tell us how interesting the fairy tale Cinderella is |
| A．is brave in expressing her love |
| B．is attended to badly by the stepmother |
| C．has a dream of meeting a prince |
| D．is embarrassed by the pop singer |
| A．Joey is just like other boys in Mary’s class. |
| B．Mary’s mother influences her a lot in singing. |
| C．Not many people have a dream to be realized. |
| D．The MP3 player helps Joey in finding Mary. |
| A．a(chǎn)n introduction to a film |
| B．a(chǎn) review about a film |
| C．a(chǎn)n essay about dreams |
| D．a(chǎn)n advertisement of Cinderella |
| A．follows Cinderella with nothing new |
