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）.

Baths and bathing have been considered of an important medical therapy to man. In Greece there are the ruins of a bath tub and water system built over 3 000 years ago. The Romans had warm public baths. In some public baths as many 3 000 persons could bathe at the same time.
Treating diseases by bathing has been popular for centuries. Modern medical bathing, or hydrotherapy, first became popular in Europe and by the late 1 700’s also became popular in the United States.
For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to be clean was avoided, and perfume(香水) was used to cover up body and smell.
By the 1 700’s doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently.
In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “the great unwashed”. In one American city, for example, a person could only take a bath every 30 days! That was a law.
Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is important to health. Doctors know that dirty bodies increase that chance of disease.    
Therefore in the United States people generally bathe often.
【小题1】What does the word “hydrotherapy” underlined in the second paragraph refer to?

A．A bathing tub.	B．Medical bathing.

People who are outdoors in cold weather should avoid actions like suddenly lifting a heavy basket full of snow. Even walking through heavy, wet snow can strain a person’s heart.
Many people aren’t conditioned to the physical stress of outdoor activities and don’t know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don’t make certain preparations.
Hypothermia means the body temperature has fallen below normal. It occurs when your body can’t produce enough energy to keep the internal (内部的) body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia.
Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they’re in danger because they can’t notice the cold conditions as quickly as the young.
Besides cold temperatures, high winds,  snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness (湿气) causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body’s heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
Don’t drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body’s important organs.
【小题1】The underlined word “strain” in Paragraph 1 means ________.

A．injure

A．they like exercising outside in cold mornings

B．they can’t notice cold conditions if they are not told

C．their body temperature is generally lower than young people’s

D．their ability to keep a normal internal body temperature is not so good

【小题4】What is Paragraph 5 mainly about?

A．What causes the body to lose heat faster.	B．The advantages of drier conditions.
C．What else can steal body heat.	D．Dangers of high winds.

【小题5】Which of the following is NOT a result of drinking alcohol before going outdoors?

A．Feeling warm at first	B．The body’s heat is taken away
C．Blood vessels in the skin expand	D．The risk of hypothermia is reduced

Exercise is an important part of a healthy life. It reduces your risk of heart attack and is a good way to control body weight. It is also something you can do with other people, which can be great fun. So, it is important to find time to exercise and be healthier. As well as making time to exercises, another way is to build it into the natural rhythm (节奏) of your day.
· Go for a walk on your lunch break.
Try to find at least three different ways and change them throughout the week. It
might even be possible to find a place to walk inside, for those bad weather days.
· Talk to your employers about improving health at work.
Encourage your workers to cycle to and from work. You might also be able to
encourage them to set up a gymnasium. Sell the idea by pointing out that doing so
will improve productivity (生产率), and make workers happy.
· If you are a student.
Go for walks with friends to talk about your studies. Spend some time in the learning
resource centre reading about sport, exercise and health. The more you know, the
more choices you will have about how to be physically active. Most colleges have
sport and exercise programs that students can take part in. Find out which activities
are being held, and try those you think you might enjoy.

C．exercising with others will be better for one’s health

D．combining exercise with daily work can save time to keep healthy

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 heads	B．headgear influences their skills
C．they should follow their idols	D．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

Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to this hospital, which usually charges patients according to the number of days they stay and the facilities(operating room, tests, medicines that they use). Some hospitals belong to a city, a state or, in the case of veteran's hospitals, a federal government agency. Others are operated by religious orders(教会) or other non-profit groups.
Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service.
Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would-be physicians first attend college for four years, which can cost nearly $ 20 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $ 10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency(实习阶段) in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low.
Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.
Physicians work long hours and must accept a great deal of responsibility. Many medical procedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.
【小题1】 According to the passage, it is very unlikely that an American hospital is owned by ______.

A．a church

B．a corporation

C．a city

D．a state

【小题2】The expenses for becoming a doctor are spent on _______.

【小题3】According to the passage, how long does it take for a would-be physician to become an independent physician in the USA?

A．About seven years.

B．Eight years.

C．Ten years.

D．About twelve years.

【小题4】Sometimes several physicians set up a group medical practice mainly because _______.

A．there are so many patients that it is difficult for one physician to take care all of them

B．they can take turns to work long hours

C．facilities may be too much of a burden for one physician to shoulder

D．no one wants to assume too much responsibility

【小题5】 Which of the following statements could fully express the author's view towards physicians’ payment in the USA?

A．For their expensive education and their responsibility, they deserve a handsome pay.

B．It is reasonable for physicians to have a large income because their work is very dangerous.

C．Physicians should be better paid because they work long hours under bad conditions.

D．Physicians have great responsibility, so it is understandable that they should be well rewarded.

Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）,prompting researchers to ask: Are cats and dogs really safe for children？
A study finds that, contrary to many parents' fears, owning cats or dogs does not increase a child's risk of developing allergies, and in fact, may actually protect them. The study's lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was "very surprised" by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
And while researchers are not encouraging parents to buy dogs or cats just to reduce a child's allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.
【小题1】Why do the researchers feel “very surprised” by the results of the study?

A．Because the results are contrary to their expectation．

B．Because so many children are playing with cats and dogs．

C．Because parents are so much worried about their children．

D．Because children with animals may develop allergies easily．

【小题2】Compared with children who have pets，those who haven’t  ______.

A．will lose the chance to develop immune system

B．may suffer allergic diseases more often

C．will reduce the harm from bacteria

D．can keep doctors away

【小题3】It can be inferred from the passage that ______．

A．pets are ill-treated by their owners

B．less families would like to own cats and dogs

C．keeping pets is a good way to keep children healthy

D．the results of the study can make families with pets feel at ease

【小题4】The underlined word “it” in the fifth paragraph refers to________.

A．the early life

B．an allergic disease

C．immune system

D．something important

【小题5】What may be the best title of the passage?

A．How to protect your kids from allergies

B．Your pets may be helping your kids

C．Bacteria do good to your kids

D．Advantages of owning pets

Dr. Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind. But he had no idea at the time that 12 - year – old Ray had the ability to become his partner in cancer research.
Ray’s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner（吸尘器）. When he was ten, he speedily constructed the family color television from a kit. Later, he succeeded in assembling（组装） a complex stereo system after two experts had failed to do the job.
When Ray was ten, he convinced his parents to buy him a computer. In a short time, Ray was able to do amazing things with the computer. Ray shared his enthusiasm for computers with Dr. Tisman, who used a computer for his research. The two discussed computers and medicine frequently. Amazingly, Ray understood the biology and chemistry related to Dr. Tisman’s medical research without any previous instruction.
Ray then worked with Dr. Tisman after school. He helped conduct research with the equipment and kept it in working order. The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins. Ray analyzed patient test results by computer, while Dr. Tisman handled all patient contact. Together, they came up with solid research that helped advance cancer treatment.
In 1988, 14 - year - old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical Research（AFCR）, where Ray presented their initial research findings. Using terminology（术语） beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients.
A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman’s research. By then, he had become well - known for his devotion to finding cures for sick patients. Stories about him appeared in hundred of newspapers around the world. He appeared on television newscasts and talk shows.
Ray continued to spend most free hours working with Dr. Tisman. The two began studying the effects of vitamins on babies inside the womb（子宫）. However, Ray’s main interest remained cancer treatment, and he continues his research today.
【小题1】According to the passage, Ray______.

A．is a boy of many gifts

B．is very helpful to his parents

C．learned fast under Dr. Tisman’s instruction

D．stopped working with Dr. Tisman after his success

【小题2】What do we know about Dr. Tisman?
