A portable lung which could help those with breathing problems lead a normal life is being developed by scientists.
The Swansea University scientists say it could take many years before the device(裝置) , the size of a spectacle box (眼鏡盒) , is available . Lung patients , who have seen how it would work , have welcomed the research.
Its research suggests that one person in every seven in the UK is affected by lung disease---- this equates to approximately 8 million people. As of 6 March 2009, 217 people were on the waiting list for a lung transplant（移植） according to figures by NHS Blood and Transplant .
Now scientists in Swansea are developing a portable artificial lung which could transform (改觀) the lives of patients . Researchers claim that in the long term the device could offer an alternative to lung transplant , giving hope to those who suffer from conditions such as emphysema(肺氣腫) and cystic fibrosis.
The device mimics the function of a lung---by getting oxygen into and carbon dioxide out of the blood stream . Professor Bill Johns came up with the idea after his son died of Cystic Fibrosis . It is important that we make something that will help people , who instead of being confined (局限) to a wheelchair with an oxygen bottle , can actually walk around and do things for themselves , he said.
Although the research has been welcomed by leading charities(慈善) , caution has also been voiced over the length of time it will take before a portable lung will become available .
“We have to stress that this is several years away from being used , even in a trial stage,” said Chris Mulholland , head of the British Lung Foundation.
Patient Elizabeth Spence from Swansea has been refused the double lung transplant she needs but remains hopeful that one day the new device could save her . “ My body will reject the lungs , so this possibly could be an answer--- another way of getting new lungs without actually having the transplant,” she said.
小題1:Which of the following about the portable lung would the author agree?
A．It can help a lot in lung transplants
B．It was once on display
C．It works differently from the normal one in the body
D．It’s just like an oxygen bottle.
小題2:It seems as if _______ really matters before the portable lung is put into use.
A．supportB．moneyC．timeD．trial
小題3:What’s the author’s attitude towards the portable lung ?
A．Negative.B．Doubtful.C．Curious.D．Objective.
小題4:Which edition can you probably find the passage ?
A．Science.B．Culture.C．Economy.D．Education.

小題1:B
小題2:C
小題3:D
小題4:A

試題分析：文章介紹了一種新發(fā)明——便攜式肺器官。這是一種只有眼鏡盒大小的裝置，可以模仿人體肺部功能把氧氣輸入血液，同時把二氧化碳排除人體血液系統(tǒng)。這給肺病患者帶來了很大希望，但是專家稱此裝置還需要很長一段時間才能投入使用。
小題1:B推理判斷題。從文章第二段Lung patients , who have seen how it would work , have welcomed the research .可知肺部患者見過這種裝置的運(yùn)作過程，由此推斷這種發(fā)明曾經(jīng)展示過，故B選項(xiàng)正確。
小題2:C細(xì)節(jié)理解題。從文章倒數(shù)第二段“We have to stress that this is several years away from being used , even in a trial stage,”可知即使是試驗(yàn)階段也得需要幾年的時間才能被使用。
小題3:D推理判斷題。A消極的；B懷疑的；C好奇的；D客觀的。從文章的整體內(nèi)容可知，作者只是介紹這種裝置，引用或轉(zhuǎn)述別人的話，而沒有加入個人的觀點(diǎn)看法，由此可知D選項(xiàng)正確。
小題4:A推理判斷題。文章內(nèi)容是關(guān)于一種新型醫(yī)療裝置，并且文章開頭提出。。。is being developed by scientists，由此判斷文章是選自科學(xué)版面。故A選項(xiàng)正確。

In the past ten years, many scientists have studied the differences between men and women. And they all got the same answer: The sexes(性別) are different, because their brains are different. And this, the scientists say, makes men and women see the world in different ways.
Boys, for example, generally are better than girls at mathematical ideas. Boys also generally are better than girls at the kind of hand and eye movements necessary for ball sports. Girls, on the other hand generally start speaking earlier than boys. And they generally see better in the dark than boys and are better at learning foreign languages.
What makes men and women better at one thing or another? The answer is the brain. The brain has two sides connected by nerve(神經(jīng)) tracks. The left side generally is used for mathematics, speech and writing. The right side is used for artistic creation(創(chuàng)造) and the expression for emotions(情感). In men and women, different areas in each side of the brain develop differently. In boys, for example, it’s the area used for mathematics. In girls, it is the area used for language skills. Another interesting difference is that the two sides of a man’s brain are connected by a smaller number of nerves than the two sides of a woman’s brain are.
小題1:Which of the following is the best title of the article?
A．Research on the Brain
B．Men and Women are Different in Brain
C．People’s Different Brains
D．Who Are Better, Boys or Girls
小題2:__________ men and women think differently.
A．The different brains make
B．Sex makes
C．The different experiences make
D．The influences(影響) of society make
小題3:According to the article, girls are generally better than boys at __________ in your school.
A．mathematicsB．physicsC．EnglishD．chemistry
小題4:Which of the following is true?
A．The left side of brain in boys generally develops better than that in girls.
B．The left side of brain in girls generally develops better than that in boys.
C．Men are better than women in all things.
D．The area in girls used for language skills develops better.
小題5:60. The number of nerves connecting the two sides of the brain in men __________.
A．is the same as women’s
B．is different from women’s
C．is larger than women’s
D．is twice as large as women’s

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”
小題1:What can we learn about Dr. Marcy from the passage?
A．He is fond of watching Jupiter.
B．He is from a scientist family.
C．He dislikes working with Paul Butler.
D．He is interested in finding life in outer space.
小題2:Which of the following is true of the recent discovery?
A．The planet is not as protective as Jupiter.
B．The planet is close to star 55Cancri.
C．The planet proves to be a gas planet.
D．The planet is as large as Jupiter.
小題3:Dr. Marcy and Dr. Butler began to find new planets in ____.
A．1995B．1985C．2002D．1981
小題4:Dr. Marcy thinks that life may exist in the 55Cancri system because ____.
A．he has found the system similar to the solar system.
B．he has discovered an Earth-like planet there.
C．he has discovered a rocky planet there.
D．he has found signs of life in the system
小題5:“But we stuck with it”( in Paragraph 3) means ____.
A．they felt discouragedB．they carried on with it
C．they failed in their attemptD．they made some progress

It is thought that crying is hardly an activity encouraged by society. Tear, whether they are of sorrow, anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears (落淚者) is likely to apologize, even when a great tragedy was the cause. The observer of tears is likely to do everything possible to put an end to the emotional tears. But judging from recent studies of crying behavior, both those responses to tears are often inappropriate and may even be counterproductive (適得其反).
Humans are the only animals clearly known to shed emotional tears. Since evolution has given rise to few purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance (increase) survival.
Although some observers have suggested that crying is a way to ask for assistance form others (as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vocal cries would have been quite enough, more likely than tears to gain attention. So, it appears, there must be something special about tears themselves.
Indeed, the new studies suggest that emotional tears may play a direct role in alleviating stress, University of Minnesota researchers who are studying the chemical composition of tears have recently isolated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance.
Other researchers are investigating the usefulness of tears as a means of diagnosing human ills and monitoring drugs. At Tulane University’s Teat Analysis Laboratory Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse, to study the causes of “dry eye” syndrome（綜合癥）and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.
小題1:What does the phrase “both those responses” in Paragraph 1 refer to ?
A．Crying out of sorrow and shedding tears for happiness.
B．The embarrassment and unpleasant sensation of the observers.
C．The tear shedder’s apology and the observer’s effort to stop the crying.
D．Linking illness with crying and finding the chemical composition of tears.
小題2:From the passage we can infer that        .
A．it is unnatural for people to shed tears
B．we can reduce our stress by shedding tears
C．shedders of tears can’t get help by crying loudly
D．unlike animals, humans can shed tears for survival
小題3:What does the passage mainly talk about?
A．Roles of emotional tears.
B．functions of shedding tears.
C．Unwelcome shedders of tears.
D．Research on the effects of tears.

Every time you go to the supermarket, you come away with your purchases in plastic bags. But wouldn’t it be kinder to the environment if you asked for paper bags instead?
The answer is not the easy as it might seem. Environmentalists say there are drawbacks to using both plastic bags and paper bags.
According to the American Plastics Council 80 percent of groceries in the US are packed in plastic bags.
“The numbers are becoming huge,” said Vincent Cobb, a businessman from Chicago who set up “reusable bags. com” on the Internet. He notes that consumers use between 500 billion and 1 trillion plastic bags per year worldwide.
Some experts believe that all these bags harm the environment. Plastic takes hundreds of years to break down and, as it does so, poisonous materials are released into the water and soil.
Further damage is caused if plastic bags enter the sea. For example, endangered sea turtles cannot tell the bags from jellyfish(水母), their main source of food, and often choke on them.
Floating plastic bags have been spotted as far north as the Arctic Ocean and as far south as the southern end of South America. One expert predicts that, within ten years, plastic bags will wash up in Antarctica!
However, this kind of bag does have its advantages.
“Plastic grocery bags are some of the most reused things around the house,” explained Laurie Kusek of the American Plastics Council.
According to the Film and Bag Federation, a trade group in the US plastics industry, paper bags use more energy and create more waste than plastic bags. Plastic bags require 40 per cent less energy to produce and cause 70 per cent less air pollution, the group explained. They also release as much as 94 percent less waste into the water than paper ones.
But paper bags do break down more quickly than plastic bags. They don’t endanger wildlife, either.
So what should we do? One possible solution would be to use biodegradable(能被生物分解的)plastic bags. But until biodegradable technology improves, it might be easier to pack things you buy in reusable cloth bags.
小題1:The best title of the passage is _____.
A．Paper Causes Less Pollution
B．Plastic Causes Less Pollution
C．Paper and Plastics Cause Pollution
D．Paper Bags Break Down More Quickly
小題2:The underlined word “drawbacks” might mean “_____”.
A．AdvantagesB．disadvantagesC．a(chǎn)ir pollutionD．waste
小題3:According to the passage, which of the following in NOT true?
A．Plastic takes longer to break down than paper.
B．Sea turtles usually mistake the plastic bags for jellyfish.
C．Paper bags require less energy than plastic bags.
D．You’d better pack things in reusable cloth bags.
小題4:Which of the following shows that paper bags are better than plastic ones?
A．Paper bags take less time to rot.
B．Paper bags cause less air pollution.
C．Paper bags are more reusable.
D．Paper bags cause less water pollution.

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.
小題2:How does Susan seem to feel about the findings of the study?
A．SatisfiedB．DoubtfulC．WorriedD．Hopeful
小題3:The best title of the text might be_______
A．The Deadliest Forms of Cancer
B．Drink Fruit Juice Instead of Sodas
C．A Study in University of Minnesota

Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(氣象學(xué)者) has done some estimates and the results might surprise you.
Let's start with a very simple white puffy cloud — a cumulus cloud（積云）. How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(懸浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn't in elephant-sized particles（微粒）, it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微調(diào)高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.
小題1:The weight of      is NOT mentioned in the passage.
A．a(chǎn) cumulus cloudB．a(chǎn) tornado
C．a(chǎn) hurricaneD．a(chǎn) storm cloud
小題2:How did Peggy LeMone feel about the result of her calculations?
A．She found it not convincing.
B．She thought it needed further calculations.
C．She was quite surprised at it.
D．She considered the calculations inaccurate.
小題3:What can be inferred from the passage?
A．A storm cloud weighs about 200,000 elephants.
B．The water in a hurricane weighs more than that in any other kind of cloud.
C．There are less than forty million elephants living on the earth.
D．The water in the cloud is in very tiny partials.
小題4:What is the best title for the passage?
A．How Much a Cloud WeighsB．How Much a Hurricane Weighs
C．Surprising ResultsD．Elephants in the Sky

The bedroom door opened and a light went on, signaling an end to nap time．The toddle（初學(xué)走路的嬰兒）, sleepy-eyed, clambered to a swinging stand in his crib．He smiled, reached out to his father, and uttered what is fast becoming the cry of his generation: "iPhone!"
Just as adults have a hard time putting down their iPhones, so the device is now the Toy of Choice for many 1-, 2- and 3-year-olds．The phenomenon is attracting the attention and concern of some childhood development specialists．
Natasha Sykes, a mother of two in Atlanta, remembers the first time her daughter, Kelsey, now 3 but then barely 2 years old, held her husband's iPhone．"She pressed the button and it lit up．I just remember her eyes．It was like 'Whoa!' "The parents were charmed by their daughter's fascination．But then, said Ms．Sykes （herself a Black Berry user）, "She got serious about the phone．" Kelsey would ask for it．Then she'd cry for it．"It was like she'd always want the phone," Ms．Sykes said．
Apple, the iPhone's designer and manufacturer, has built its success on machines so user-friendly that even technologically blinded adults can figure out how to work them, so it makes sense that sophisticated children would follow．Tap a picture on the screen and something happens．What could be more fun?
The sleepy-eyed toddler who called for the iPhone is one of hundreds of iPhone-loving toddlers whose parents are often proud of their offspring's ability to slide fat fingers across the gadget's screen and pull up photographs of their choice．
Many iPhone apps on the market are aimed directly at preschoolers, many of them labeled "educational," such as Toddler Teasers: Shapes, which asks the child to tap a circle or square or triangle; and Pocket Zoo, which streams live video of animals at zoos around the world．
Along with fears about dropping and damage, however, many parents sharing iPhones with their young ones feel guilty．They wonder whether it is indeed an educational tool, or a passive amusement like television．The American Academy of Pediatrics is continually reassessing its guidelines to address new forms of "screen time．" Dr．Gwenn Schurgin O'Keeffe, a member of the academy's council, said, "We always try to throw in the latest technology, but the cellphone industry is becoming so complex that we always come back to the table and wonder- Should we have a specific guideline for them?"
Tovah P. Klein, the director of a research center for Toddler Development worries that fixation on the iPhone screen every time a child is out with parents will limit the child's ability to experience the wider world.
As with TV in earlier generations, the world is increasingly divided into those parents who do allow iPhone use and those who don't. A recent post on UrbanBaby.com, asked if anyone had found that their child was more interested in playing with their iPhone than with real toys. The Don't mothers said on the Website: "We don't let our toddler touch our iPhones ... it takes away from creative play." "Please ... just say no. It is not too hard to distract a toddler with, say ... a book."
Kathy Hirsh-Pasek, a psychology professor who specializes in early language development, sides with the Don'ts. Research shows that children learn best through activities that help them adapt to the particular situation at hand and interacting with a screen doesn't qualify, she said.
Still, Dr. Hirsh-Pasek, struck on a recent visit to New York City by how many parents were handing over their iPhones to their little children in the subway, said she understands the impulse (沖動). "This is a magical phone," she said. "I must admit I'm addicted to this phone."
小題1:The first paragraph in the passage intends to ______.
A．get us to know a cute sleepy-eyed child in a family
B．show us how harmful the iPhone is
C．lead us to the topic of the toddlers' iPhone-addict
D．explain how iPhone appeals to toddlers
小題2:According to the author, iPhones are popular with both adults and young kids because they are______.
A．easy to useB．beautiful in appearance
C．cheap in priceD．powerful in battery volume
小題3:The underlined word "them" in the seventh paragraph refers to ______.
A．televisionsB．cellphonesC．iPhonesD．screens
小題4:The tone of the author towards parents sharing iPhones with their children is ______.
A．negativeB．subjectiveC．objectiveD．supportive
小題5:The passage mainly tells us ______.
A．children's iPhone addict is becoming a concern
B．iPhone is winning the hearts of the toddlers
C．Apple is developing more user-friendly products
D．ways to avoid children's being addicted to iPhone games

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.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly bombarded with products that are hazardous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reverse damage to some extent.
