    All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.
    Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible.
    Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
    Establish a pre-bedtime rule that will help focus you on sleep. You can try meditation（沉思）,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is the best for you.
    Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences（干扰）.

    His first fight was for the equal rights of black people in South Africa. Then, as the first black president he fought to unite the country and organize the government. Now Nelson Mandela has set his sights on a new enemy, AIDS.
    On March 19 the 82-year-old, former president, hosted his second AIDS-awareness concert. He warned that 25 million people in Africa were already infected with the fatal disease.
    Mandela was born in a small village in South Africa in 1918. He was adopted (收养) by the chief of his tribe (部族) and could have been a chief himself and lived a happy country life.
    But he refused to be a chief when his people lived under racial discrimination ( 种族歧视). He decided to fight for equal rights for all the people in South Africa. Before 1990, under the country’s Racial Segregation Law (种族隔离法), colored and white people lived separately. Black people were treated unfairly even when taking a bus. Blacks had to stand at the back of the bus to make room for white people even when there were only a few of them on board.
    For his opposition (反对) to the system Mandela was arrested (被捕) and spent 27 years in prison. He was freed in 1990 and become the president of the country after the first elections were held in which everyone could vote.
    Mandela was not only a political fighter who attacked with speeches. He was also a trained boxer (拳击手) and fought in the ring when he was young.
    “ Although I did not enjoy the violence of boxing, I was interested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat (撤退),” he wrote in his autobiography.
    As a skilful fighter, he chose music as his weapon against AIDS. He hopes to win another victory against AIDS.
    小题1:Nelson Mandela succeeded in doing the following except _____.
    A．winning the equal rights for the black people in South Africa
    B．uniting South Africa

    小题2:If Nelson Mandela hadn’t fought against racial discrimination, he _____.
    A．could easily have been the president of South Africa
    B．could still have lived a happy life
    C．could have been in a difficult situation
    D．would have been an excellent boxer
    小题3:It can be inferred that Nelson Mandela _____.
    A．continues to help the black people with the political struggle
    B．is taking a position in a music group
    C．is taking on the world’s greatest fight against AIDS

    Compared to the other parts of the body, our ears don’t ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones.
    Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from your parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.

    A healthy amount of sunshine may be the secret to staying young. British scientists have discovered.
    Vitamin D is produced naturally by the skin in response to(对…的反应) sunlight and may help to slow the ageing process and protect against heart disease, according to the study.
    Researchers from King’s College London studied 2,160 women aged between 18 and 79, looking at their telomeres--- a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible(易受伤害的) to certain illnesses.
    But the study found women with high levels of vitamin D had comparatively longer telomeres--- a sign of being biologically younger and healthier.
    The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.
    Lead researcher Dr Brent Richards said, “These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D.” This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer.”
    Professor Tim Spector, a co-author of the report, added, “Although it might sound absurd
    (荒唐的), it’s possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process.”
    Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body’s supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals(粥).
    Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.
    小题1: A certain amount of sunshine helps people stay young because _____.
    A．people feel happy and energetic in the sun
    B．sunshine protects people against heart disease
    C．vitamin D makes one’s skin look young and healthy
    D．vitamin D may help to slow the ageing process
    小题2:From Brent Richards, we know that _____.
    A．sunlight causes skin cancer to people with high level of vitamin D
    B．the study generally has a healthy effect on the general ageing process
    C．vitamin D can only be got from fish, eggs and breakfast cereals
    D．the higher levels of vitamin D people have, the more slowly people may age
    小题3:What can we infer from the passage?
    A. Telomeres are important signs of ageing of the DNA.
    B. Sunlight can be dangerous as it causes skin cancer.
    C. Sunlight does a great deal of good to our health.
    D. Vitamin D can also be gained from food.
    小题4: What is the best title of the passage?
    A．Secret of Staying Young
    B．Vitamin D Helps Slow Ageing
    C．Sunlight and Vitamin D
    D．Sunlight and Health

    A number of scientific studies have suggested that repeatedly heading a football could increase the risk of developing dementia (痴呆症) in later life.
    In 2002, former England international footballer Jeff Astle died aged 59. A coroner (验尸官) said that Astle died from a brain disease likely to have been caused by “repeated small damages to the brain” related to heading a heavy leather football.
    Dr. Scott Delaney, research director of emergency medicine at McGill University Health Center in Montreal, Canada, has also researched soccer-related head injury and agrees that head-to-head or elbow-to-head blows are the real risk.
    In 2007, Delaney carried out a study on footballers aged between 12 and 17 that showed they were half as likely to be concussed (使脑部受到震荡) wearing headgear (帽) than without.
    He said youngsters have a higher risk of head injury than adults because their heads are thinner and less able to absorb shock. To make matters worse, their neck muscles aren’t as well developed and they often lack the correct heading technique that can help throw away the force of the ball.
    Delaney recommends that children wear headgear when playing football and says his two eldest children wear head protection playing the sport. But he admits that children can be unwilling to be the first to wear head protection—especially when their football heroes play without it.
    While headgear can protect footballers from being concussed during a match, no one knows the long-term effects of repeated “sub-concussive” blows to the head.
    Delaney says that while there is indirect evidence that a career in soccer can lead to dementia, no one has yet found a sure link between the two. He says proving a link would mean monitoring hundreds of footballers for three or four decades—and that would take a lot of funding.
    小题1:Which might be the best title of the passage?
    A．Playing football may lead to brain damage.
    B．Repeated small damages to the brain.
    C．Footballers should wear headgear when playing. .
    D．Evidence to dementia.
    小题2:According to Delaney’s research, what is the most risky injuries to head?
    A．Long-term effects of blows.
    B．Wearing head protection.
    C．Underdeveloped neck muscles.
    D．Head-to-head or elbow-to-head blows.
    小题3: Children are unwilling to wear headgear because they think _____ .
    A．headgear is harmful to their headsB．headgear influences their skills
    C．they should follow their idolsD．they mustn’t lead the fashion
    小题4:It can be inferred from the last paragraph that _____ .
    A．Delaney has studied dementia for three or four decades
    B．few footballers would like to be studied in the research
    C．funding is important in order to carry out the research.
    D．no one can find the link between playing football and dementia

    In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat if you pick them up within 5 seconds after dropping them.      
    But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria（细菌）to make you sick.
    Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.
    One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.
    But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna（一种大红肠）on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.
    So, forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. And this time, be careful not to drop it!
    小题1:In which part of a newspaper can you most probably find this passage?
    A．CultureB．HealthC．AdvertisementD．Technology
    小题2:After dropping a piece of toast, a person who follows the “5-second rule” will         .
    A．throw away dirty toast immediately and go away
    B．pick up the toast as quickly as possible and eat it
    C．eat the toast within 5 seconds and feel pleased
    D．get another piece of clean toast quickly and eat it
    小题3:The scientists in South Carolina did the experiment to __________ .
    A．see how quickly bacteria can pollute food
    B．show that the 5-second rule is correct
    C．see how harmful bacteria are to people’s health
    D．show that bacteria grow at different speeds on different foods

    Doctors have known for a long time that extremely loud noises can cause hearing damage or loss.The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little mire than one second to be affected.
    An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
    The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.

    A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.
    Researchers from the University of Yale based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanomas (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
    Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.
    But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
    The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles (雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.
    The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
    小题1:The underlined word “flaws” in the 2nd paragraph most probably means           .
          
    A．evidencesB．factsC．faultsD．failures
    小题2:People with fair skin and freckles           .
          
    A．seldom use sunscreenB．are more in danger of skin cancer
    		C．can be free from the harm of the sunD．often expose themselves to the sun
    小题3:We can learn from the passage that          .
          
    A．sunscreen users get skin cancer more often
    		B．the volunteers have proved the effect of sunscreen
    		C．the new study was based on the experiences of volunteers
    		D．the number of skin cancer patients is increasing in America
    小题4:Which of the following can be the best title for this passage?
          
    A．Sunscreen to Prevent Skin Cancer
    B．Sunscreen to Increase Skin Cancer
    		C．Skin Cancer Caused by Sunscreen
    		D．Skin Cancer Caused by Freckles
