Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime(消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.
【小题1】According to the text, what kind of children may eat more unhealthy food?

A．Those who often do sports.

B．Those who often watch television.

C．Those who often have meals at home.

D．Those who often walk to school.

【小题2】The author thinks that children are becoming overweight because ______.

A．they can't choose what to eat

B．they are too busy to go out and play

C．their parents often cook meals for them

D．there are too many fast food shops around

【小题3】The word "steering" underlined in the last sentence most probably means ______.

A．forcing

B．guiding

C．driving

D．moving

【小题4】The main purpose of the text is to ______.

A．tell a story

B．provide facts

C．give advice

D．compare opinions

“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
【小题1】We need _____for a healthy diet.

A．Fruit provides us with energy and fibre.

B．Some healthy problems start because of a lack of water.

C．Drinking more water may stop people from overeating.

D．The amount of water a person should drink in a day.

As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
【小题1】The author says that the world population is increasing because _____.

A．there are many rich valleys and large fields

B．farmers are producing more crops than before

C．people are living longer due to better living conditions

D．new lands are being made into farmlands

【小题2】The author says that in areas with large populations, land might be more productively farmed if _____.

A．the land was divided into smaller pieces

B．people moved into the countryside

C．industrial methods were used in farming

D．the units of land were much larger

【小题3】We are told that there are now farms beyond the Arctic Circle. This has been made    possible by _____.

A．growing new types of crops	B．irrigation and dry-farming means
C．providing fertilizers	D．destroying pests and diseases

【小题4】 Why do some people use dams to hold back waters from great rivers?

A．To develop a new kind of dry-farming methods.

B．To prevent crops from floods.

C．To provide water and electricity in all seasons.

D．To water poor lands in bad weather.

阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。
A
“I sometimes get up at three or four in the morning and I surf the net.”
“I often check my e-mail forty times a day.”
“I often spend more than three hours during one time on the net.”
“I spend more time in chat rooms(聊天室) than with my ‘real-1ife’ friends.”
Do you know any people like these? They are part of a new addiction(瘾) called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose control(控制)of the time they spend on the Internet
For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.
Studies show that about 6 to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them.They spend more time in cyberspace than in the real world of friends and family.
Is “surfing the net” a hobby or an addiction for you? You may have a problem if
you have these symptoms(症状):
●You do not go to important family activities or you do not do school work because you like to spend hours on the Internet.
●You can’t wait for your next online time.

Every hour spent in watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research claims that a sedentary(久坐的) lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be associated with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."
【小题1】We can learn from the passage that_______

A．whether you watch TV or not has nothing to do with how long you will live

B．if an adult watches TV for six hours every day, he will die five years earlier

C．physical inactivity and obesity won't shorten your life

D．a sedentary lifestyle offers huge benefits.

【小题2】The word "it" in the second paragraph refers to

A．a sedentary lifestyle

B．eating

C．smoking

D．obesity

【小题3】What do we know from the last three paragraphs?

A．People in the United Kingdom watch TV longer than those in the United States.

B．That a sedentary lifestyle carries additional risks isn't supported by other studies.

C．Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%.

D．It is through these studies that we know a sedentary lifestyle carries additional risks.

【小题4】The passage is intended to _______.

A．inform the readers of a research on watching TV

B．warn the readers of the harm of watching TV and hope they do sports

C．tell the readers watching TV is also a good way to relax

D．tell the readers large amounts of people often watch TV

Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across America’s 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 farmers.
Ryan Best, president of Future Farmers of America, has been living out of a suitcase, traveling the country and visiting 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 (创新) 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.”
【小题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.

【小题2】Why is Merrigan visiting universities across the country?

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.

【小题3】According to Matt Rush, American agriculture will provide opportunities for younger people because ____________.

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

Office workers should know that long periods of sitting at your desk may be a killer. Scientists have shown a new threat from this lifestyle that they call  “muscular inactivity (肌肉迟钝)”．
Sitting still for long periods of time leads to the buildup of substances (物质) in the blood that are harmful to health. And exercise alone won’t drive them away.
Millions of people spend their days between car，office desk and the sofa in front of the TV. While the bad influences are well rocognized，it has been thought that they can be changed by regular trips to the gym or swimming pool.
Now researchers say that is not enough. In addition to regular exercise，office workers need to keep moving while they work，by making regular trips to the printer，coffee machine or to chat with workmates.
Elin Ekblom­Bak，an expert on health，says research shows long periods of sitting and lack (缺乏)  of “whole body muscular movement”  are strongly linked to obesity，heart disease and cancer，and a higher risk of death，regardless of (不管) whether they take enough exercise.
“Everyone knows about the health benefits of regular exercise. But what we haven’t realized before is that long­period sitting down carries an extra risk that cannot be dealt with by taking exercise，” Dr Ekblom­Bak said，adding that sitting still should be recognized as a risk to health.
“It is important to have a five­minute break from desk work every 45 minutes. Don’t email workmates—walk across the office to give them the message. Take a coffee break or put the printer in the next room. I am a desk worker and I try to do it. It is not difficult but sometimes you get lost in your work and you forget about it.”
However，more studies are needed to confirm the ill effects of sitting for too long and ways of fighting them. But at present they conclude that  “keep moving”  should be added to the advice to “keep exercising.”
【小题1】Nowadays，many office workers wrongly think that________.

A．long periods of sitting has bad influences on them

B．regular exercise benefits them after long periods of sitting

C．they are living a lifestyle called “muscular inactivity”

D．it’s unfair for them to sit in the office for too long

【小题2】What does the author suggest office workers should do?

A．Chat with workmates often.

B．Send emails instead of chatting.

C．Keep moving in the office regularly.

D．Take more exercise after work.

【小题3】The last paragraph suggests that the result of the study is________.

A．scientific

B．uncertain

C．unbelievable

D．convincing

【小题4】What would be the best title for the passage?

A．A new threat ：long­period sitting

B．Office workers should keep exercising

C．Taking exercise benefits a lot

D．Keep moving，it could save your life

If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory（记忆力） is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
【小题1】The main reason for one’s poor memory is that _______.

A．his father or mother may have a poor memory

B．he does not use his arm or legs for some time

D．they will become neither stronger nor weaker

【小题3】Which of the following is NOT true?

A．Your memory works in the same way as your arms or legs.

B．Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice.

C．Don’t learn how to read and write if you want to have a better memory.

D．A good memory comes from more practice.

【小题4】Some people can’t read or write, but they usually have better memories, because _______.

 A new survey finds that more than eighty percent of Internet users in the United States search for health information online. The survey found that searching online is one of the leading ways that people look for a second opinion though doctors are still the main source of health information.
Forty-four percent of people are actually looking for doctors or other providers when they search for health information online. Another finding of the survey: Two-thirds of Internet users look online for information about a specific disease or medical condition.
The Internet has also become an important source of emotional support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition. It was more popular among people with more serious health issues—one in four people living with chronic diseases (慢性病). And it was basically off the charts with people living with rare disease. They are so eager to find other people online who share their health concerns.
A disease is considered rare if it affects fewer than two hundred thousand people worldwide. The rise of social networking has made it easier for people with rare diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other. Dr. Jeff Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients.
“We provide the patient full access to their medical care. Anything I can see, the patient can see. All of their notes, all of their doctor visits are right there. All of their lab work is right there.” Dr. Livingston says the software has increased efficiency, reduced costs and improved relations with patients.
【小题1】From the first paragraph, we can know _________.

A．most online health information is reliable

B．more people now turn to the Internet for medical advice

C．people shouldn’t rely on the Internet for medical advice

D．doctors are no longer the patients’ first choice

【小题2】 The underlined words “off the charts” in Paragraph 3 mean _________.

A．very popular

B．not accessible

C．far away from

D．not attractive

【小题3】 By using social networking, patients with rare diseases can _________.

A．find effective cures	B．get emotional comfort
C．ask for financial support	D．consult doctors anytime

【小题4】 Which of the following is NOT true of Dr. Livingston’s software?

A．It cuts down medical expenses.

B．It decreases the time spent on medical care.

C．It takes doctors closer to their patients.

D．It gives patients a medical test online.
