11.If you think that running marathons will help you live a long and healthy life,new research may come as a shock.According to a recent scientific study,people who do a very  strenuous  workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000joggers and non-joggers for 12years.The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die.The best speed to jog at was found to be about 5miles per hour.The research suggests that people who jog more than three times a week or at higher speeds of over 7mph die at the same rate as non-joggers.The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉).Over time,this can cause serious injuries.
Peter Schnohr,a researcher in Copenhagen,said,"If your goal is to decrease risk of death and improve life expectancy,jogging a few times a week at a moderate pace is a good strategy.Anything more is not just unnecessary,and it may be harmful."
The implications of this are that moderate forms of exercise such as t'ai chi,yoga and brisk walking may be better for us than"iron man"events,triathlons and long-distance running and  cycling.According  to  Jacob  Louis  Marott,another researcher involved in the study,"You don't actually have to do that much to have a good impact on your health.And perhaps you shouldn't actually do too much."

32.The underlined word"strenuous"in Paragraph 1is closest in meaning to"A".
A.hard           B.regular
C.practical      D.flexible
33.The author presents some figures in Paragraph 2toC.
A.suggest giving up jogging
B.show risks of doing sports
C.provide supportive evidence
D.introduce the research process
34.According to the scientists,why is too much exercise harmful?A
A.It may injure the heart and arteries.
B.It can make the body tired out.
C.It will bring much pressure.
D.It consumes too much energy.
35.What can be inferred from the text?D
A.No exercise at all is the best choice.
B.More exercise means a healthier life.
C.Marathons runners are least likely to die.
D.Proper exercise contributes to good health.

分析 最新的一项科学研究显示:从事剧烈运动的人与根本不锻炼的人死亡几率是一样的,而适度的锻炼会有益于健康.

解答 32.A  词义猜测题.此处指像马拉松一样的锻炼,所以strenuous 应与hard意思相近,表示"艰苦的,费力的".regular"定时的";practical"实用的";flexible"灵活的".
33.C  写作目的题.作者在第二段中采用了列数字的方法,是为了提供支持的证据,能更有力地说明第一段的研究结论.
 34.A  细节理解题.根据第二段的最后两句"The scientists think    that this is because strenuous exercise causes structural changes    to the heart and arteries(动脉).Over time,this can cause    serious injuries"可知,剧烈运动会导致心脏和动脉结构发生变化,从而有损健康.
35.D 推理判断题.根据最后两段可知,过度锻炼不仅没有必要,而且还可能有害,适当的锻炼会有助于健康.

点评 阅读理解题测试考生在阅读基础上的逻辑推理能力,要求考生根据文章所述事件的逻辑关系,对未说明的趋势或结局作出合理的推断;或根据作者所阐述的观点理论,对文章未涉及的现象、事例给以解释.考生首先要仔细阅读短文,完整了解信息,准确把握作者观点.

1.A study published in September suggests there is a surprising way to get people to avoid unhealthy foods:change their memories.Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities and food experiences."One week later,"Loftus says,"we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences."Some accounts included one key additional detail:"You got sick after eating strawberry ice-cream."The researchers then changed this detail into a manufactured (人为促生的) memory through leading questions"Who were you with?How did you feel?"By the end of the study,up to 41% of those given a false memory believed strawberry ice-cream once made them sick,and many said they'd avoid eating it.
When Loftus published her findings,she started getting calls from people begging her to make them remember hating chocolate or French fries.Unfortunately,it's not that easy.False memories appear to work only for foods you don't eat on a regular basis.But most important,it is likely that false memories can be implanted (灌输) only in people who are unaware of the mental control.And lying to a patient is immoral,even if a doctor believes it's for the patient's benefit.
Loftus says there's nothing to stop parents from trying it with their overweight children,"I say,wake up.Parents have been lying about Father Christmas for years,and nobody seems to mind.If they can prevent diseases caused by fatness and all the other problems that come with that,you might think that's a more moral lie.Decide that for yourself."

76.Why did Loftus ask the volunteers to answer some questions?C
A.To improve her computer program.
B.To find out their attitudes towards food.
C.To find out details she can make use of.
D.To predict what food they'll like in the future.
77.What did Loftus find out from her research?B
A.People believe what the computer tells them.
B.People can be led to believe in something false.
C.People tend to forget their childhood experiences.
D.People are not always aware of their personalities.
78.According to the study,people may stop having a certain food if theyD.
A.learn it is harmful for health
B.lie to themselves that they don't want it
C.are willing to let doctors control their minds
D.think they once had a bad experience of eating it

A.Whether it is moral.  B.Who it is best for.
C.When it is effective. D.How it should be used.
2.Bottled water has become the choice for people who are healthy and thirsty.Bottled water is all over the world.But some say the planet's health,and people's health may be suffering from it.
The idea that bottled water is safer for humans may not be true.The Natural Resources Defense Council of America said,"There is no promise that because water comes out of a bottle,it is cleaner or safer than water from the tap."Another New York City-based action group added that some bottled water is"really just tap water in a bottle-sometimes more clean,sometimes not."

It is not proven that bottled water is better than tap water.Nick Reeves from the Chartered Institution of Water and Environmental Management said,"The high mineral content (含量) of some bottled water makes them not good for feeding babies and young children."Also,most bottled water doesn't have fluoride (氟化物),which can make teeth stronger.Kids are drinking more bottled water and less fluoridated tap water,and some say that's behind the recent rise in bad teeth.
Storing is another problem.Placed near heat,the plastic bottles can produce bad chemicals (化学物质) into the water.
According to the Environmental Protection Agency,some 2.7 million tons of plastic are used worldwide to bottle water each year.The plastic can take between 400 and 1,000 years to break down.
In terms of energy use,plastic bottles are also not cheap.One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles,they would have saved about 72 million gallons of gas.
So,if you are worried about the effect of bottled water on the Earth,you can take the following steps.
●Drink from your tap.Unless your government warns against this,it should be fine.
●Get a container (容器).Carry your tap water in a steel or a lined drinking container,and clean it between uses.
●Keep it cool.Don't drink from a bottle that has been sitting in the sun,don't store it near chemicals,and don't reuse plastic bottles.
●Choose glass containers over plastic if possible.When finished,recycle!
48.What is the main idea of the article?D
A.Drinking tap water is the only choice for people.
B.Glass containers are better than plastic bottles.
C.Plastic bottles are harmful to the environment.
D.Bottled water may not be as good as we think.
49.What can we learn about plastic bottles from the article?C
A.They break down in less than 300 years.
B.They can be used for many other things.
C.They are a risk to the environment.
D.They are cheap to make.
50.According to the article,we can know that bottled water isB
A.no problem for the environment       
B.more expensive than tap water
C.always safer than tap water           
D.better for babies
51.Which of the following about tap water is NOT mentioned in the article?A
A.There are a lot of problems storing tap water.
B.Bottled water can be just tap water in a bottle.
C.It may be better for your teeth.
D.It may contain fluoride.
16.A Good Night's Sleep
Sleep plays a vital role in good health and well-being throughout your life.While you're sleeping,your brain is forming new pathways to help you learn and remember information.Although we all know the importance of getting a good night's sleep,not all of us know the best way of getting it.A sleep expert,Phil Atherton,gave some top tips for getting the most out of the night,which will leave you ready for action in the morning.
According to Phil Atherton,not eating a large meal before bedtime is important for getting a good night's sleep.The time difference between eating and sleeping should be at least three hours.So you'd better avoid eating any food three hours before bed,as it will lower your blood sugar during sleep and help minimize damage from too much sugar floating around.
It's also important to find ways to prepare your body for sleep.You can follow a routine like trying not to expose yourself to too much artificial light within 1hour before bed,as your brain uses light to help set internal"body clock".Although it might seem unnatural to schedule your sleep,the purpose is to send a signal to your body and mind that it's time to sleep.
Another way to prepare your body for sleep is to get into a relaxed state by taking a bath or listening to soft music.Both of them will help to take the mind off the daytime pressures.
Having a suitable bed,especially a suitable mattress (床垫),is necessary for a good night's sleep.Sleep is a personalized activity,and we all adopt different sleeping positions.Finding the mattress that suits you will reduce back pains that can result from a poor sleeping position.The bed should be four to six inches longer than its tallest user,allowing for space to move around.
The recent research is pretty clear that a good night's sleep in a major component of good health.Since the start of the 21st century,studies have linked a lack of sleep to many diseases,such as diabetes and obesity.Taking action now will lead to long-term benefits for you and those around you.
28.What does the author intend to tell us in the passage?B
A.When to start a sound sleep.
B.How to get a good night's sleep.
C.What to do with sleep problems.
D.Why to form a good habit of sleeping.
29.According to the author,before going to sleep,you'd betterD.
A.record your biological clock  
B.check your blood sugar
C.relieve your pain in the back  
D.free yourself from tension
30.What does the underlined word"it"in Paragraph 2refer to?A
A.Not eating food.
B.Taking a meal.
C.Not eating a large meal.
D.Having a good sleep.
31.Which of the following shows the organization of the passage?C

CP:Central Point P:Point Sp:Sub-point (次要点) C:Conclusion.
3.Health experts have long known that vitamin D is important for healthy bones and teeth.It may also help to protect the body against diseases such as diabetes and cancer.And now,researchers say vitamin D might help fight brain diseases called dementia (痴呆).
Dementia is a brain disease that damages thinking and memory processes,which scientists call"cognitive (认知) abilities."Dementia is difficult to treat.Taking care of someone who has dementia is extremely demanding.And the disease is very frightening to sufferers.Chris Roberts suffers from dementia.He says the worst part of living with this disease was getting lost while driving."The worst thing that I found was getting lost in the car,not just forgetting where I was going-I wouldn't know where I was."More than 47million people around the world suffer from dementia.The World Health Organization reports that 60percent of them live in low-and middle-income countries.
We get vitamin D from some foods like nuts,lentils (扁豆) and fatty fish.We also get vitamin D from the sun.But that is not dependable.In some parts of the world,there is not enough sunlight to provide enough vitamin D.Also,sunblock prevents the vitamin from entering the body.To add to the problem,the skin's ability to process vitamin D weakens as a person ages.
Researchers at Rutgers University in New Jersey are exploring the relationship between vitamin D and dementia.The team recently measured vitamin D levels and cognitive ability in older people.Nutritional sciences professor Joshua Miller led the team.He said cognitive abilities differed among the study subjects.He said tests showed that about 60percent of the group was low in vitamin D.
32.Which of the following is true about vitamin D?B
A.Vitamin D can decrease people's risk of heart diseases.
B.Vitamin D helps the body fight against cancer.
C.Vitamin D is mainly obtained from the sun.
D.The need for Vitamin D decreases as people age.
33.What does the underlined word"demanding"mean in Paragraph 2?D
A.Boring but rewarding.
B.Disturbing and frightening.
C.Disgusting and stressful.
D.Hard and tiresome.
34.What does Paragraph 3mainly talk about?B
A.How vitamin D affects people's health.
B.Where people get vitamin D.
C.Whether sunlight can produce vitamin D.
