While there has been public debate about whether running is good for your health for a long time, experts agree that running has more benefits than the costs. Some people are concerned that the pressure on your knees and ankles can be detrimental. While this can be true, there are many things that you can do to reduce your risk of injury.
You should always go to a doctor for advice before you begin any type of exercise program. Then, a good pair of running shoes can be helpful as your feet hit the ground. They will help protect your ankles by providing stability to your feet. So it is good idea to visit a specialty(专业) running shoe store. The staff there can suggest shoes which are ideal for your running style.
In order to learn the proper form, you may get some advice from a friend who has been running for some time, or even join a running club. They can provide good tips as well as some support and encouragement for you.
Lastly, it is important to start out slowly. When it comes to getting in shape and losing weight , short bursts of speed followed by periods of slower movement would be proper. Aim for around 30 minutes of exercise a few days a week. As you get better, you can increase your speed. Always allow your body to rest in between heavy exercise as your muscles need time to bring energy back.
Follow these instructions and your running experience will be a great one!

A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.
David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.
And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.
These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.
Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.
Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
【小题1】What is the passage mainly about?
| A．Teens’ sleep is linked to their relationship with people around them. |
| B．Lack of adequate sleep puts teens at risk of many bad consequences. |
| C．Modern technology has something to do with teens’ sleep problems. |
| D．It is necessary for teens to join in sports and positive social activities. |
| A．Teens who feel like talking with their parents. |
| B．Teens who have friends sharing their dreams. |
| C．Teens who feel contented about themselves. |
| D．Teens who lack a sense of security at school. |
| A．a comparison | B．an introduction | C．a conclusion | D．an addition |
| A．continue their broken marriage | B．allow children to decide when to sleep |
| C．limit teens’ using new technology | D．force teens to have 10 hours’ sleep daily |

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(调查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

| A．stories and explanations |
| B．examples and investigations |

| D．facts and descriptions |
| A．Being focused while eating is a good way to have a good figure. |

Studies show that children who eat breakfast do better in school. It doesn’t take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast.
If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel (食物). By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day.
Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn’t true; the body expects to be refueled a few times a day, starting with a healthy breakfast. Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight.
A healthy breakfast should have some protein (蛋白质) and some fiber (纤维). Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested (消化) quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time.
【小题1】The first paragraph mainly tells us that ______.
| A．it is necessary to have a good breakfast every day |
| B．many adults are too busy to have breakfast every day |
| C．many adults go to work without having breakfast |
| D．many children go to school without breakfast |
| A．we need to have a cup of coffee | B．we don’t have a good breakfast |
| C．our brains don’t work any longer | D．we don’t have enough sleep at night |
| A．Having a good breakfast can help you to finish your work. |
| B．Eating a good breakfast is enough for the whole day. |
| C．Breakfast is really the most important meal in a day. |
| D．You will be happier if you have a good breakfast. |
| A．it is healthy only to have beans and eggs for your breakfast |
| B．you mustn’t have meat for your breakfast |
| C．you should eat sugary foods if you feel hungry |
| D．you should eat something which has protein and fiber for breakfast |

Below is some advice on how to prevent cancer:
8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon（结肠） cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate（石榴）Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.
3. Relax
Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of stressing about the past or future, focus on the present and relax!
4. Take Selenium（硒）
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate（前列腺） cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi（寿司）
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp（节省）on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
There’s no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物质） in their urine（尿） than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a percent lower risk of metastasis(转移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.
【小题1】To prevent yourself from catching colon cancer, you should eat ____ as often as possible.
| A．sushi | B．blueberries | C．pomegranates | D．Vitamin D |
| A．he is very fond of exercise every day. |
| B．he is addicted to smoking |
| C．he is always feeling extremely stressed or worried |
| D．he likes to have meals in restaurants |
| A．have a daily supplement of vitamins B and C |
| B．try to ignore the secondhand smoking |
| C．take in as many selenium-containing supplements as possible |
| D．having exercise as often as possible |

Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.
Opposite to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
【小题1】During the test, those who were tested were given ________.
| A．no breakfast at all | B．very rich breakfast |
| C．little food for breakfast | D．different breakfast or none |
| A．he will fall ill |
| B．he will fail to listen to his teacher |
| C．he will not make progress in his studies |
| D．his mind will work more slowly |
| A．breakfast has great effect on work and studies |
| B．breakfast has little to do with a person’s work |
| C．a person will work better if he has a simple breakfast |
| D．those working with brains should have much for breakfast |
| A．Poor breakfasts affect those who work with brains. |
| B．Morning diet may cause one to get fatter. |
| C．Reducing lunch and supper is of less value in weight losing. |
| D．Eating less in lunch and supper may help to lose weight. |

The research tracked the health of 101,000 US nurses over three decades.
Light-to-moderate smokers were twice as likely to die of sudden heart problems as those who had never smoked.
But those who quit smoking saw their risk begin to go back down within years, a journal of the American Heart Association reports.
_________
During the study, there were 315 sudden cardiac deaths（心脏性猝死）——where the heart unexpectedly stops working.
In people aged 35 or younger, this usually because of a heart condition that runs in the family.
But in people who are older than this—as most of the nurses in the study were —it can be the first sign of coronary heart disease, where the heart’s arteries become blocked by fatty deposits.
Of the 315 sudden deaths in the study, 75 were among current smokers, 148 were among recent or past smokers and 128 occurred in people who had never smoked.
Reason to quit
After taking into account other heart risk factors, such as high blood pressure, high cholesterol and family history of heart disease, Dr Roopinder Sandhu and his colleagues found the women who smoked were twice as likely as likely to die suddenly even if they smoked “light-to-moderate” amounts —between one and 14 cigarettes a day.
For every five years of continued smoking, the risk went up by 8%.
But women who quit saw their risk fall to that of someone who had never smoked, after 20 years of cessation.
Dr Sandhu, of the University of Alberta, Canad, said: “What this study really tells women is how important it is to stop smoking. The benefits in terms of sudden cardiac death reduction are there for all women, not just those with established heart disease.”
“It can be difficult to quit. It needs to be a long-term goal. It’s not always easily achievable and it may take more than one attempt.”
Ellen Mason, senior cardiac nurse at the British Heart Foundation, said: “This study shows that smoking just a couple of cigarettes a day could still seriously affect your future health.”
“As we approach the new year, many of us will be making resolutions and giving up smoking will be the top of the list for lots of people.”
“If you’re thinking of quitting and need a nudge, this research adds to the wealth of evidence that stopping smoking is the single best thing you can do for your heart health.”
A recent study in The Lancet of 1.2million Women found those who gave up smoking by the age of 30 would almost completely avoid the risk of dying early from tobacco-related diseases.
Latest figures suggest a fifth of women in England smoke.
【小题1】According to the research, light smokers____________.
| A．are not likely to suffer from heart problems |
| B．are more likely to suffer from heart problems than moderate ones |
| C．can go on smoking only if they don’t smoke much |
| D．have a high possibility of dying of heart disease |
| A．Nonsmokers wouldn’t die of sudden cardiac death |
| B．Most of the nurses concerned in the research were middle aged. |
| C．All age groups of people were involved in the research. |
| D．If the smokers had quit smoking, they wouldn’t have died of heart disease. |
| A．Raised risk | B．Ways of quitting smoking |
| C．Diseases related to smoking | D．Signs of heart disease |
| A．push | B．confidence | C．study | D．comparison |

Malaria, the world's most widespread parasitic(寄生虫引起的) disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
【小题1】According to paragraph 1, many people don't seek care because___.
| A．they can remain unaffected for long |
| B．it is unusual to seek care |
| C．they are too poor |
| D．there are too many people suffering from the disease |
| A．have to kill female mosquitoes |
| B．have ability to defend parasites |
| C．have their red blood cells infected |
| D．have sudden fever, followed by chills |
| A．Its outbreaks in cities with large populations. |
| B．Its ability to pass on the virus frequently. |
| C．Its resistance to global warming. |
| D．Its ability to defend itself and resist new drugs. |
| A．no drugs have been found to treat the disease |
| B．the alternative treatment is not easily available to most people |
| C．malaria has developed its ability to resist parasites |
| D．nobody knows what will be the drug to treat the disease |
| A．How can we know one is suffering from malaria? |
| B．How many people are killed by malaria each year? |
| C．Why are there so many people suffering from malaria? |
| D．What has been done to keep people unaffected for long? |

The Green Microgym in Portland，Oregon has all the usual stuff you'd expect-sweaty people，loud music，smooth exercise equipment-but it has some extras as well. Everywhere you look，there are power wires. And these aren't the typical kind that let you surf the Web while you ride a spin cycle-although. you can do that too．The gym uses special exercise equipment that captures（捕获）the energy you create while riding, converts（转换）it into electricity and channels it into the power outlets（插座）．
The idea of using exercise equipment to produce electricity is not new. A gym in Hong Kong has been doing this since 2007. But clean (and healthy）energy is just now starting to catch on in U. S. gyms·"We have seen a significant increase in interest in the past six months，which is a good sign that fitness centers are ready to spend money on green technologies，” says Mike Curnyn，co-founder of the Green Revolution，a Connecticut-based firm that wires bikes into a central battery that can store energy.
The Green Microgym，first opened in 2008，has more than 200 members and is doing so well that owner Adam Boesel opened another one five miles from the original．Although membership costs about the same as ordinary gyms，customers can earn gift certificates from local businesses for watts produced while exercising．An average workout creates 37. 5 watt hours，which is enough to power a phone for a week．
Boesel uses spin bikes made by Resource Fitness，a Seattle company he co-owns，that captures energy produced from the flywheel. Wires send the converted AC current（交流电流）into any standard wall outlet-for this reason，the product line's name is Plug Out-and the energy created is used before the building draws power from the grid（电网）．Unlike the Green Revolution equipment，Plug Out machines cannot store extra energy. A third company，the Florida-based ReRev，is adding converters to a specific brand of spin bikes. But since the converters add＄1，000 to the price of the equipment，the ReRev and Green Revolution machines are at a disadvantage．
Resource Fitness，by contrast，sells its equipment for the same＄1，200 price as non- electricity-producing machines，removing the question of how long it will be until the energy savings pay for the cost of the unit．The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters．It is also trying to price competitively with standard equipment so more gyms-and gym goers-will make the switch．
【小题1】Members of the Green Microgym earn gift certificates for_______．
| A．using the man-powered exercise equipment |
| B．saving electricity for local businesses |
| C．producing green electricity to power their phones |
| D．paying higher membership fees |
| A．they are easier to ride |
| B．they are more expensive |
| C．they don't have wires connected |
| D．they can not store extra electricity |
| A．People's unwillingness to go green． |
| B．The high cost of making it. |
| C．Safety problems concerning electricity. |
| D．Lack of certificates． |
| A．change to a different gym |
| B．use green exercise equipment |
| C．switch on the spin bikes |
| D．add a battery to the machine |
