A woman wears a face mask to protect her from polluted air in Lanzhou, China, in December．
A new study showed air pollution might put people more at risk for heart disease than scientists had thought．Kristin Miller, a doctoral student at the University of Washington, said chances of getting the disease were related to not only which city a woman lived in, but also where in the city．The study found that the effects of air pollution were often larger within cities than between cities．
The new findings make experts suspect that current pollution limits may be inadequate．Scientists examined rates of heart attack, stroke （中风） and other cardiovascular （心脏血管的） events in women with long-term exposure to air pollution．
The study involved women over the age of fifty who had no sign of cardiovascular disease at the start of the research．The study followed the women for as long as nine years to see how they would develop cardiovascular problems．
The researchers also examined levels of fine particles （粒子，微粒） in the air in 36 areas across the country．That information came from the Environmental Protection Agency．The extremely small particles came from industrial smoke and traffic, along with things like wood-burning fireplaces in houses．
In the study, every ten-microgram increase in pollution was linked to a twenty-four percent increase in the risk of a cardiovascular event．But it was related to a seventy-six percent increase in the risk of death from cardiovascular disease．
But just how do particles in the air damage the cardiovascular system? The particles may cause the lungs to swell and release chemicals from the pollutants into the blood．The chemicals then could damage the heart．
1．The passage mainly talks about______．
A．the effects of pollution on women
B．how to protect women from air pollution
C．how air pollution damages a person’s heart
D．the relationship between air pollution and heart diseases
2．The case of the woman wearing a face mask shows ______．
A．people are paying more and more attention to their health
B．the woman is afraid of getting heart disease
C．Lanzhou city is more heavily polluted than other cities
D．air pollution is becoming more and more serious
3．We can learn from the passage that _______．
A．air pollution is more serious than scientists thought
B．the control of air pollution is effective in some cities
C．people throughout a city have the same risk of getting heart diseases
D．air pollution affects women more than men
4．The study implies that ______．
A．air pollution has a bigger effect on older women than younger women
B．small particles in the air mainly come from industrial smoke
C．the rise in air pollution may lead to a higher death rate from cardiovascular disease
D．air pollution has been affecting people for as long as nine years in the city of Lanzhou

For most pregnant women, exercise is the last thing on their minds. After all, keeping slim while you’re expecting isn’t exactly the top priority— rather, it’s making sure your baby gets enough nutrients to grow. But in a small new study, researchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exercise may be good for a growing fetus’ health — and may even help a baby get a healthier start in life.
The finding is a bit surprising, because exercise is known to lower the risk of insulin resistance（胰岛素抵抗），a condition eventually leading to diabetes（糖尿病）. Although insulin resistance is a detriment in healthy adults, it turns out to be helpful for proper fetal（胎儿）development. In pregnant women, this condition means nutrients get shunted to the growing baby.
The question is: could a mother’s exercise put her developing baby’s food supply at risk? Past studies looking at the effect of exercise on birth weight have been inconclusive, and none have really investigated the influence of exercise on the mother’s sensitivity to insulin. So the University of Auckland’s Dr. Paul Hoffman and his team decided to study 84 first-time mothers, who were of normal weight on average, and track any effects aerobic exercise(有氧运动) might have on their insulin sensitivity and, ultimately, on their babies’ birth weight. Researchers asked some women to exercise on a stationary bicycle for at least 40 minutes per session, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exercise. When the two groups and their babies were compared, the team found that women who bicycled regularly gave birth to babies who were on average 150g lighter than those born to the non-exercising mothers. In both groups, however, the babies were of healthy weight, and there was no difference in the mothers’ weights.
Generally speaking, babies on the lower end of the normal weight range are considered healthier and less prone to developing diabetes and obesity than heavier ones, so this was an encouraging result. Even more reassuring was that regular exercise did not seem to affect the flow of nutrients to the growing babies in the womb.
1. According to the new study, a pregnant woman’s regular exercise may _______.
A. bring benefits to a baby’s growth
B. lower the risk of insulin resistance
C. put her baby’s food supply at risk
D. help her keep slim and healthy
2. What does the underlined word “detriment” mean in the second paragraph?
A. Something that brings good.
B. Something that brings damage.
C. Something that brings obstacles.
D. Something that brings development.
3. What is the purpose of the experiment carried out by Dr. Paul Hoffman?
A. To investigate the influence of exercise on pregnant women.
B. To find out what aerobic exercise can benefit a baby’s growth.
C. To make sure of the effects exercise may have on babies’ birth weight
D. To compare the differences between mothers who exercise and who don’t
4. Which of the following statements is true according to the passage?
A. Lighter babies are generally believed to be healthier than heavier ones.
B. Non­－exercising mothers will definitely give birth to heavier babies.
C. No studies have looked at the effect of exercise on birth weight before.
D. Some women studied were asked to exercise regularly while some don’t.
5. Which of the following may be the best title for the passage?
A. All mothers should take aerobic exercise.
B. Moms who exercise give birth to lighter babies。
C. Exercise reduces the risk of insulin resistance.
D. Heavier babies are more likely to develop diabetes.

The Food and Drug Administration is, again, threatening to impose(征税) milk and meat from cloned animals on a public that opposes the technology and its products.
Respected polls report that more than 60% of Americans think animal cloning is immoral, and that most people said they wouldn’t knowingly eat the products even if the FDA approved them. But because the FDA would allow cloned meat and milk to be sold without identifying labels, consumers wouldn’t be able to avoid them. The FDA has consistently tilted toward those who want cloned milk and meat in our food. Agency officials have repeatedly asserted that science shows cloned milk and meat are safe for humans. But the FDA has never published the complete scientific studies it says support that claim.
The argument that cloning is safe for animals is unconvincing. Cloned meat and milk offer no public economic benefits. Having cloned cows produce more milk wouldn’t reduce milk prices. US farmers produce more milk than we drink, and the government is required to buy the surplus. Since 2000, dairy support programs have cost taxpayers more than $ 5 billion.
Most important, this first decision to advance animal biotechnology raises ethical issues beyond the FDA’s expertise（专家意见）. Techniques used to clone animals will advance the ability to clone humans－and create animals with human genes. Neither the agency nor animal scientists are qualified to tell us whether and when it is ethically acceptable for humans to alter the essential nature of animals. We need a national discussion, including ethicists and religious leaders, to consider the wisdom of cloned and transgenic animals. Given the risk of unintended consequences, we should proceed cautiously. The president should halt further FDA action on cloning and set in motion(运作) a process for beginning this broader discussion.
1. The author’s attitude towards cloning is __________.
A. standing in the middle      B. opposed     C. approving     D. supportive
3. In US many people buy cloned foods __________.
A. to support the new technique
B. because FDA approved them
C. because they cannot tell which is cloned food
D. because they cannot read the labels.
3. From the text we know that cloning technique ___________.
A. developed well enough to clone human beings
B. may cause unintended bad results to human beings
C. will bring more unexpected economic benefits
D. is supported by ethicists and religious leaders
4. What’s the best title of this passage?
A．Public Is Against Cloned Food     B．Benefits of Cloned Food
C．Cloned Food Is Illegal            D．Technique in Cloned Food

第Ⅱ卷 (非选择题共35分)
第四部分写作 (共两节，满分35分)
第一节任务型阅读(共10小题；每小题1分，满分10分)
认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
注意：每个空格只填1个单词。请将答案写在答题卡相应题号的横线上。
Attention deficit (不足) hyperactivity (活动过度) disorder is known by the letters A. D. H. D. with A. D. H. D. might have trouble paying attention. They might not seem to listen and might forget things. They might not be able to stay seated or play quietly. They might talk too much and act and speak without thinking about the results of their behavior. These are among the signs named on the web site of America's Centers for Disease Control and Prevention.
Doctors usually identify the disorder in children. But experts say the behaviors often last into adulthood. Researchers have been looking for the cause or causes of attention deficit hyperactivity disorder. Now, a brain-imaging study offers more evidence that could lead to new ways to treat it. Researchers say they observed shortages in the brain's reward system in patients with A. D. H. D. The study found that levels of some proteins were lower than normal. Nora Volkow, director of the National Institute on Drug Abuse, says the lack of attention and self-control that mark A. D. H. D. could be caused by problem in the flow of dopamine (多巴胺) . She says people might have difficulty completing an activity if they cannot expect some kind of reward in return. Researchers studied the pathways on which dopamine travels in 53 adults with A. D. H. D. Doctor Volkow says the researchers then compared the pathways to those of 44 adults without the disorder. "There was a lower concentration of dopamine markers in the brain of individuals with A. D. H. D., specifically in the areas of the brain that are involved with reward and motivation. And the dopamine levels were directly linked to the severity, of the patient's inattention" she says.
The study used brain images taken at Brookhaven National Laboratory in New York State. Gene -Jack Wing is chairman of the Brookhaven medical department. He says the finding might also help explain why people with A. D. H. D. are mere likely to abuse drugs or overeat. He says they might be attempting to increase their dopamine levels to make up for the deficits in their reward system.

For many young people, the dream of a lifetime is to travel the world, explore different cultures and landscapes, taste new foods and flavors, and listen to the distinctive sounds of international music and languages.
Unfortunately, few young people have the money or freedom to make this dream come true. But if you can't go out into the world, surely second best is to let the world come to you. And, this year's Shanghai World Expo is exactly where that's happening.
From May 1 to October 31, there will be 194 countries and 50 international organizations on display at the 5-square-km Expo site. Seventy million domestic and international visitors are expected to visit it by the end of October. So, if you can go, you'll be surrounded by people with a wide range of backgrounds, nations, and cultures.
The Expo's theme is "Better City, Better Life". The United Nations estimates that, this year, 55 of the world's people will live in urban settings. This poses a dilemma (困境) for the world's cities: How can they accommodate such a large number of people in a sustainable (可持续的) way? Can they remain places of natural beauty and cultural importance?
Well, that's the challenge the 2010 Expo participants are confronting in a variety of ways. Japan will show off an "eco-breathing" structure to power its building with natural energy like sunlight, rainwater and wind. Germany's pavilion is named "Balancity", which is described as a "balance between innovation (创新) and nature, society and its individuals, work and recreation" (娱乐)
The first themed Expo was held in 1933, and since that time World Expos have featured a participatory and interactive style. The Shanghai Expo is no exception. Young people will have the opportunity to take part in forums to discuss themes like new technology, green energy and conservation.
A trip to the Expo is guaranteed to be much less expensive than a trip around the world. Still, the costs can add up. However, young people can save money by purchasing group or student tickets, which may be available at reduced rates. Many of the participating pavilions offer free samples and treats for the visitors. In addition to handing out free chocolates, the Belgian pavilion will give away a free diamond each week to a visitor who can answer questions related to Belgium.
If you're planning to head to the Shanghai Expo between May and October, don't forget to bring a camera, a notebook, and an open mind (and comfortable shoes). For nearly six months, representatives of the world are coming together to share their best and latest ideas for the future. It's sure to be a memorable experience.

Cuts
Bleeding can usually be stopped by applying pressure to the cut for 2 or 3 minutes. The cut can then be carefully inspected. If it has bled freely any germs will normally have been washed away by the blood.
Apply a plaster dressing firmly, bringing the edges of the cut together so that it knits quickly. Keep dry for 1 to 2 days.
If the cut is deep and the edges cannot be pulled together with a dressing consult the doctor or the practice nurse. A tetanus (破伤风) injection may be needed.
Grazes
Dirt will often enter a graze caused by falling on a hard or rough surface. It must be cleaned out carefully with an antiseptic solution. (消毒液)
After cleaning, leave the graze uncovered. Exposure to the air will cause a scab to form. This will gradually fry and fall off.
It is not a good idea to apply a dressing. This may stick to the graze or make it complete wet and infected.
Bruises
Bruises are very common in children. They normally get better in 7 to 10 days Parents sometimes worry that a bone may be broken, but if in doubt consult the doctor.  If a child gets up at once after a fall and moves about normally, it is unlikely that a bone has been broken.
Severe bruising can be treated by： Rest for 24 to 48 hours .In the case of a badly bruised leg, the limb should be raised. Lying in bed is the easiest way to do this.
A bad compress may ease a bad bruise if applied at once. This is made by leaving some material in water and applying it to the bruise.
Insect bites
These are common in the summer .They look like spots about 1/4’’across .They are very itchy (痒) and usually appear on exposed parts, e.g. arms and legs.
The itching can be relieved by calamine lotion (护肤药水).
Burns and scalds
Minor burns and scalds cause redness of the skin. Immediate treatment by pouring cold water over a burn is often helpful. If burns cause the skin severe hot or break the skin, the doctor should be turned to.
Sunburns should, if possible, be prevented by avoiding long exposure and covering exposed areas as much as needed. It may be treated by calamine lotion to relieve the pain.

Sports can help you keep fit and get in touch with nature．However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment．
Some sports are resource-hungry．Golf, as you may know, eats up not only large areas of countryside, but also tons of water．Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition．This causes major environmental effects．For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas．
There are many environment-friendly sports．Power walking is one of them that you could take up today．You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse．Simple and free, power walking can also keep you fit．If you walk regularly, it will be good for your heart and bones．Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control．
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials．But the final goal should be “green gyms”．They are better replacements for traditional health clubs and modern sports centers．Members of green gyms play sports outdoors, in the countryside or other open spaces．There is no special requirement for you to start your membership．And best of all, it’s free．
1．The author thinks the golf is resource-hungry because of the following EXCEPT that_____．
A．Golf wastes large areas of countryside
B．Golf runs out of much water
C．Keeping golf court in good condition needs too much energy
D．Golf is bad for people’s health

A．show us the function of major sports
B．encourage us to go in for green sports
C．discuss the major influence of popular sports
D．introduce different types of environment-friendly sports

.Can you imagine your doctor warning that taking a bath could be unhealthy? In the early 1800s, many doctors thought that bathtubs(浴缸) could carry diseases, so they advised against their use. The advice wasn’t based on personal experience, because few of the doctors owned bathtubs. The White House did not even have a bathtub until 1851.
In the 19th century, only one home out of six had a bathroom. A child took only one bath a week. On Saturday nights, children all lined up for their turns to wash in a wooden bathtub in the kitchen. Mothers had to boil the water on the stove and carry it over to fill the bathtub. It’s no wonder that children could not jump into a bathtub as they do today.
When the first bathtubs were introduced, even their makers weren’t sure whether the new fashion would last. They advertised their products as water containers that “could be used as bathing tubs”.
The bathtub became popular in America shortly after World War I. By then most middle-class families had indoor taps. At first most bathtubs were made of wood, but as the popularity of the product increased, so did the creativity of bathtub makers. Before porcelain(瓷) bathtubs there were rubber ones like the plastic swimming pools kids use today. In the past few years owners often invited guests to see them. They told their friends how wonderful baths in these bathtubs could be.
Now doctors no longer warn that bathtubs carry diseases. Instead, they tell their patients about the benefits of frequent bathing in the bathtubs. Maybe one of the best reasons why doctors encourage frequent trips to the bathtub is that bathed patients smell better!
47. Many doctors in the past were against using bathtubs because ______.
A. they didn’t have their own bathtubs
B. they thought bathtubs could carry diseases.
C. the children might hurt themselves in the bathtubs
D. bathtubs were too expensive for the common families
48. Why couldn’t children jump into a tub in the 19th century as they do today?
A. It was unhealthy to do so.      B. The bathtubs were not enough.
C. Mothers were always busy.     D. The bathtubs were made of wood.
49. Which of the following is true according to the text?
A. Some different materials can be used to make bathtubs.
B. In the 19th century only one home out of seven had a bathroom.
C. The bathtub became popular when they were introduced to the market.
D. Children prefer the bathtubs made of plastic to those made of porcelain.
50. It can be inferred from the last paragraph that ______.
A. all the doctors have bathtubs in their homes
B. the doctors have realized the advantages of bathtubs
C. the doctors will make lots of money by advertising bathtubs
D. the patients should take a bath before going to see a doctor

Cricket
About the game:
Cricket is a game played between two teams, generally of 11 members each. Essentially, it is single combat, in which an individual batsman does battle against an individual bowler, who has helpers known as fielders. The bowler throws the ball from one end of the 22-yard pitch in an attempt to dismiss (send out) the batsman by hitting a target known as the wicket at the other end, or by causing the batsman to hit the ball into the air into a fielder's grasp. The batsman attempts to defend the wicket with the bat and to score runs, by striking the ball to the field boundary, or far enough from the fielders to allow the batsman to run to the other end of the pitch before the ball can be returned. There are always two batsmen on the field, each to take a turn as required. When all but one of the batting team, altogether eleven of them, have been dismissed, the teams' roles are switched. After all the players required to bat on both sides have done so either once or twice (which can take from a few hours to five days) the total number of runs accumulated determines the winner. But sometimes there isn't one.
Important terms of cricket:
Batsman: A player who uses a bat to hit, or guide the ball after it has been bowled, usually for the purpose of scoring runs.
Boundary: Indicates the outer limit of the playing area.
Bowler: Refers to a player who’s primarily good at throwing a ball to a batsman. The basic goal is to get the ball past the batsman and break the wicket behind him with it and thus cause the batsman to be dismissed.
Catch: If a fieldsman catches a struck ball before it touches the ground, that is a catch and the batsman is out.
Fielder: A player placed within the field, with the object of stopping the batting team from scoring runs, also called “fieldsman”.
Four: If the ball is hit to bounce or roll over the boundary, this is a "boundary four"; four runs are added.
Run: The method of scoring during a game of cricket. Also refers to a single unit of score.
Six: If the batsman hits the ball clear over the boundary on the fly, six runs are added to the score.
Umpire: A person appointed to rule on plays in cricket.
64. What’s the right order of the four kinds of people (1—4 ) on the cricket ground (see picture on the right ) ?
A. bowler; umpire; batsman; fielder          B. batsman; umpire; fielder; bowler
C. fielder; bowler; batsman; umpire          D. bowler; umpire; fielder; batsman
65. What happens when the batsman hits the ball, which first touches the ground inside the pitch and rolls quickly over the boundary to one of the viewers outside the cricket ground?
A. The batsman gets dismissed.             B. The batting side gets four runs.
C. The batting team gets six runs.           D. The bowler’s team gets four runs.
66. We can learn from the passage that ________.
A. the side which has all its batsmen dismissed wins the game
B. the side which dismisses all batsmen of the other side wins the game
C. the side which gets more runs than the other side wins the game
D. the side which dismisses more of the other side’s batsmen wins the game 

Burn Calories in Your Sleep?
The weight-loss world is full of assertions（断言）, rarely proved, that some pill can help you “burn calories while you sleep.” But a recent Dutch study reports that it can be done – simply by eating more lean protein（无脂肪蛋白质）.
Researchers report for the first time that consuming nearly a third of daily calories as lean protein – for example, lean meats without the skin – speeds up a person’s metabolism（新陈代谢） during sleep and that higher protein intake increases the burning of calories and fat during the day. Plus, when the study’s participants, who were all women of healthy weight, ate more protein, they felt fuller, more satisfied and less hungry than when they consumed a diet with the amount of protein, about 10 percent of calories.
The findings suggest that adding lean protein to your daily food “enables you to reach the same level of satiety（过饱）that you are used to with about 80 percent of your normal energy intake,” notes Margriet Westerterp-Plantenga. “That means you can eat about 20 percent less and still have the same satiety.”
What gives protein its caloric edge? It’s more difficult for the body to metabolize protein than either fat or carbohydrates（糖类）. The body also doesn’t store protein as efficiently as it does carbohydrates or fat. So protein is more likely to be burned and that in turn requires more oxygen and helps you feel satisfied in the hours after eating.
But the latest findings don’t mean it’s time to dust off those high-protein diet books. The current study limited fat to about 30 percent of daily calories, and included 40 percent of calories as healthy carbohydrates, including fruit and vegetables. For example, lunch included bread, soy milk, fruit yogurt, tuna in water, tomatoes, cucumbers, feta cheese and salad dressing.
54. According the first paragraph, we know that ______.
A. there’re few studies on weight-loss in the world
B. many studies on weight-loss only cheat customers
C. only few studies are useful for weight-loss
D. there’re few studies about lean protein
55. According to the passage, lean protein can help burn calories while you sleep because ______.
A.it can slow down a person’s metabolism   
B. it’s difficult for the body to metabolize
C.it will not make you feel full  
D. it’s easy to be stored in the body
56. The underlined phrase “dust off” in the last paragraph means ______.
A. get rid of                   B. put away     
C. get ready to rewrite          D. get ready to reuse
57. The passage is mainly to tell readers ______.
A. there is a good diet for weight-losers
B. you can burn your calories in your sleep
C. high-protein diet books will be popular
D. choosing right food is of great use
