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（動脈）．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 最新的一項科學研究顯示：從事劇烈運動的人與根本不鍛煉的人死亡幾率是一樣的，而適度的鍛煉會有益于健康．

解答 32．A  詞義猜測題．此處指像馬拉松一樣的鍛煉，所以strenuous 應與hard意思相近，表示"艱苦的，費力的"．regular"定時的"；practical"實用的"；flexible"靈活的"．
33．C  寫作目的題．作者在第二段中采用了列數(shù)字的方法，是為了提供支持的證據(jù)，能更有力地說明第一段的研究結論．
 34．A  細節(jié)理解題．根據(jù)第二段的最后兩句"The scientists think    that this is because strenuous exercise causes structural changes    to the heart and arteries（動脈）．Over time，this can cause    serious injuries"可知，劇烈運動會導致心臟和動脈結構發(fā)生變化，從而有損健康．
35．D 推理判斷題．根據(jù)最后兩段可知，過度鍛煉不僅沒有必要，而且還可能有害，適當?shù)腻憻挄兄诮】担?/p>

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 （人為促生的） 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 （灌輸） 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．a(chǎn)re willing to let doctors control their minds
D．think they once had a bad experience of eating it
79．What is the biggest concern with the method？A
A．Whether it is moral．  B．Who it is best for．

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 （化學物質(zhì)） 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．a(chǎn)lways 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 （床墊），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．

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 （癡呆）．
Dementia is a brain disease that damages thinking and memory processes，which scientists call"cognitive （認知） 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．
D．Why people's age influences the production of vitamin D．
35．Where can we most probably read the passage？C
A．In a travel brochure．
B．In a literature magazine．
C．In a science journal．
D．In a commercial advertisement．
