题目内容

According to the survey conducted by some scientists, it is common to have difficulty sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift（轮班）work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap (小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications (药物治疗) may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.

Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.
Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.
小题1:We may learn from Paragraph 1 that_________.
A．the decline of exercise rates is newly discovered
B．the study suggests 31% of female adults get too little exercise
C．the good enough data has been collected from only one country
D．the industrial revolution has changed the way people live to some degree

A．have little time to exercise
B．hate to get regular exercise
C．take more exercise to lose weight
D．exercise more than men in their country
小题3:The underlined word “slothful” in Paragraph 3 most probably means_________.
A．powerfulB．richC．lazyD．unpopular
小题4:What can be the best title for the text?
A．Worldwide Lack of Enough Exercise
B．New Health Discovery

D．Benefits of Taking Exercise
Putting in water fountains(饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage(饮料) consumption.
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.
Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.
小题1:According to the text, the journal Pediatrics__________.
A．may cover the subject of the health of children
B．mainly deals with the water drinking problem
C．is mainly about the mental health of kids
D．must be a journal entitled(授权) by a school
小题2:What do we know about the survey from the text?
A．The teacher were also encouraged to drink water.
B．The students surveyed were all overweight.
C．It surveyed children in the countryside.
D．It lasted for a whole school year.
小题3:The fifth paragraph is mainly about __________.
A．the technique used in the surveyB．the benefits of the survey
C．the process of the surveyD．the result of the survey
小题4:What can be learned from the last paragraph?
A．Drinking water definitely decreases appetite.
B．Further research is needed to confirm the finding.
C．The experts will encourage all the students to drink water.
D．Why students drinking more get less pounds will be clear soon.
Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened for new tumors (肿瘤) or doesn’t it?
While such tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it s important to weigh the health benefits of screening against the risks and costs of routine testing.
In many cases, screening can lead to additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained (根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social groups.
It’s hard to uproot deeply-held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy.
A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening—especially considering the explosion of the elderly.
It’s not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves from medical disputes. We need to think about the wise use of health care, which means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.”
小题1:Routine cancer screening for the elderly people makes sense because ______.
A．it is believed to contribute to a long life
B．it is part of their health care package
C．they are more sensitive about the health
D．they are in greater danger of tumor growth
小题2:How do some researchers now look at routine cancer screening for the elderly?
A．It adds too much to their medical bills.
B．They are doubtful about necessity.
C．It helps increase their life expectancy.
D．They think it does more harm than good.
小题3:What is the traditional view about women screening for breast cancer?
A．It is a must for adult women.
B．It applies to women over 50.
C．It is intended for young women.
D．It doesn’t apply to women over
小题4:Why do many doctors advise routine screening for cancer?
A．They want to take advantage of the medical care system.
B．They want to protect themselves against medical disputes.
C．They want data for medical research.
D．They want their patients to suffer less.
小题5:What does the writer say is the general view about health care?
A．Better care, longer life.
B．Prevention is better than cure.
C．Better early than late.
D．The more, the better.
Have you ever been bitten? Of course you have. You are surrounded by living things which might, or do, bite. Even when you rest your head on your pillow, bedbugs are probably nibbling away(蚕食) at you. They live happily inside most pillows.
Take a walk outside and you are a target for “man’s best friend. ” Hundreds of dog-bite victims visit US emergency rooms daily. Many bites are terrible. To avoid the dogs in your neighborhood, you might want to hike into the desert or the woods. There, you run the risk of bites from rattlesnakes, scorpions, and blood-sucking ticks. Not to mention bears, wolves, coyotes, and mountain lions.
Speaking of housing, watch out when you touch the corner of your house or garage. Shy but deadly, the black widow spider and the brown recluse spider make themselves comfortable in quiet areas of your closets or garage. One bite from either of them can make you very sick; occasionally, people die from such bites. Unfortunately, many people fear all spiders, not just the few dangerous ones. They squash them or run from them at first sight, not realizing that most spiders are actually beneficial to man.
If you’re concerned about bites, don’t forget about rabid(患有狂犬病的) animal bites. Any warm-blooded animal can get infected with rabies. Although humans in the US rarely get attacked by rabid animals, the disease is painful and dangerous. You will most likely die if you are not treated properly within 48 hours of being bitten.
小题1: How does the author introduce the topic of this passage?
A．By asking questions.B．By giving examples.
C．By offering suggestions.D．By doing experiments.

A．①④B．②③C．③⑤D．②④
小题4:What can we infer from the 3rd paragraph?
A．All spiders are dangerous and one bite from each of them can be very serious. .
B．The black widow spider is actually beneficial to humans.
C．Spiders always make themselves comfortable in quiet place in your house.
D．One should squash a spider at first sight to keep safety.
小题5:In the author’s opinion, __________.

C．Humans in the US can be bitten by rabid animals frequently.
D．Hundreds of rabid animal-bite people visit emergency room daily in the US.
The World Health Organization (WHO) planned to study the relationship between the eating habits of the people and the disease. Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries. They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa. The diseases were similar and could therefore all be named kwashiorkor. The diseased children are usually from one to four years old. As the illness progresses, the child’s stomach becomes swollen by liquid collecting in the body. The skin changes color and may break out in open sores（疼痛）. The hair changes color and starts to fall out. The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time. Stomach liquids are no longer produced.
The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat. Their mothers, after stopping their breastfeeding, gave them foods full of starches（淀粉）instead of greatly needed proteins. They found that the addition of milk to the food of the children suffering from kwashiorkor saved many lives.
The unbelievable thing about kwashiorkor is that the very existence of the disease—which has been killing thousands of children for centuries—was not even recognized in Latin America as recently as ten years ago. The deaths of those children were mistakenly listed as due to other diseases. It was the WHO’s work in Africa that led to the discovery of the problem in Central America.
小题1:From the passage we learn that kwashiorkor is a disease caused by __________ .
A．poor living conditionsB．lack of proteins in food
C．breastfeedingD．lack of food
小题2: It is difficult to discover kwashiorkor because ____________________ .
A．it has no symptoms at all
B．it is hard to identify signs of it
C．it doesn’t last long enough for careful observation
D．it is hardly different from other diseases
小题3:What is mentioned as a simple but reasonable way of curing this disease?
A．Taking a special medicine.
B．Avoiding any food containing starch.
C．Having more meat or milk.
D．Taking medicine full of proteins.
小题4:What’s the best title for the article?
A．Milk and Meat Are Daily Necessities
B．Kwashiorkor and Improper Eating Habits
C．A New Form of Illness in Africa and Latin America
D．A Case of Eating Habits
In today's fast-paced (快节奏) society, few people take time to enjoy the midday meal．Most of us just rush right through it. We grab a quick salad, or buy a sandwich and eat at our computers, Sometimes, if there is a deadline around the corner, we just skip lunch．
The development of technology hasn't done our eating habits much good either．We are constantly distracted by e-mail, social media, and 24 - hour news．Even when we do sit down for lunch, we are more connected to our hand - held electronic devices．
Long working hours can cause all kinds of health problems, and many developed countries have put in place labor laws specifically regarding the lunch break．These laws give employees the right to take a break during a long work shift, but it's up to them whether they do so or not．
Frank Partnoy, a former Wall Street trader, says that employers should encourage workers to take time off for lunch．This is because long lunch breaks can benefit both individuals and society.
Writing in The Guardian, Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective（认识）． A break from work allows us to think strategically and outside the box．It also puts our daily tasks into a broader context（背景）．
What we eat at lunch is also important．In Partnoy' s opinion, a fast food lunch is more harmful than not having lunch at all．  And it's not just about calories and unhealthy food．Recent studies show that fast food also has negative effects on how we think．
However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down, something that hardly can be achieved in a noisy and over — packed fast food chain．
Despite these benefits, some employees might still be unwilling to take time off for lunch．Partnoy's suggestion? Make skipping lunch difficult: Employers could ask workers to fill out a form stating their reasons for skipping the meal．
小题1:What does the underlined phrase "skip lunch" mean in the first paragraph?
A．have a quick lunchB．don't have lunch
C．work while having lunchD．take a lunch break
小题2:Which of the following is true according to the text?
A．Modern technology results in good diet habits．
B．Electronic devices make our life comfortable．
C．Many people are too busy to have a good lunch．
D．Laws have passed to make workers have lunch．
小题3:According to Frank Partnoy, long lunch breaks            .
A．are time for the workers to relax their mind
B．make the employees work longer hours
C．are for employees to have a quick lunch
D．make the workers eat a proper lunch at home
小题4:In Partnoy's opinion, a fast food lunch                .
A．saves a lot of time for a rest
B．affects people's way of thinking
C．is better than having no lunch
D．makes workers sit down and think
小题5:What might be the author's purpose in writing the text?
A．To warn us not to eat fast food．
B．To introduce Frank Partnoy's opinion．
C．To encourage us to work more efficiently．
D．To show the importance of a proper lunch．

What happens inside the skull of a soccer player who repeatedly heads a soccer ball? That question motivated a challenging new study of the brains of experienced players that has caused discussion and debate among soccer players, and some anxiety among those of us with soccer-playing children.
For the study, researchers at the Albert Einstein College of Medicine in New York selected 34adults, men and women. All of the volunteers had played soccer since childhood and now competed year-round in adult soccer leagues. Each filled out a detailed questionnaire developed especially for this study to determine how many times they had headed a soccer ball in the previous year, as well as whether they had experienced any known concussions (脑震荡) in the past.
Then the players completed computerized tests of their memory and other learning skills and had their brains scanned, using a complicated new M.R.I. technique which can find structural changes in the brain that can't be seen during most scans.
According to the data they presented at a Radiological Society of North America meeting last month, the researchers found that the players who had headed the ball more than about 1,100 times in the previous 12 months showed significant loss of white matter in parts of their brains involved with memory, attention and the processing of visual information, compared with players who had headed the ball fewer times.
This pattern of white matter loss is "similar to those seen in traumatic (外伤的) brain injury", like that after a serious concussion, the researchers reported, even though only one of these players was reported to have ever experienced a concussion.
The players who had headed the ball about 1,100 times or more in the past year were also generally worse at recalling lists of words read to them, forgetting or fumbling the words far more often than players who had headed the ball less.
小题1:The passage is most probably a______.

C．story for soccer playersD．text for doctors
小题2:In which way can we find the structural changes in the brain?
A．Computerized test.B．Questionnaire..

C．nothing to do with the brain injuryD．one's memory improved
小题4:What is likely to be the cause of memory loss?
A．Playing soccer frequently.B．Tests of their memory.
C．White matter loss.D．Information processing.
小题5:The underlined word "fumbling" is closest in meaning to______.
