Drinking wine in moderation improves the IQ and may boost mental agility in old
题型：不详难度：来源：
A study of the effects of alcohol on the middle aged and elderly found the average IQ of men who drink wine (whether made from grapes or rice) was 3.3 points higher than that of men who do not imbibe.
Similarly,the IQ of women drinkers showed an improvement of 2.5 points over their teetotal sisters.The findings are part of an ongoing study by Japan’s National Institute for Longevity into the links between human intelligence and what we eat and drink.
The tests measured general knowledge,powers of judgment and concentration in drinkers and non-drinkers over 40,all living in Aichi prefecture,central Japan,and sharing the same income level-roughly￡50 000 a year—and educational background.All were university graduates.
But while wine-drinkers appeared to be brighter,the same was not true of those who drank deer,shochu (a local gin) and whisky.
“The benefits of wine and sake (rice wine) in raising IQ could be due to substances they contain,such as polyphenol,which are believed to slow the ageing process,” Hiroshi Shimokata,head of epidemiology research,said.
It was premature to conclude,he added,that drinking wine or sake slowed the deterioration of brain functions in the elderly,or warded off senility.The research does,however,suggest that this is one way to stay mentally alert longer.
But there is a sobering caveat:drinking too much may make you dimmer.“People who drink more than 540 milli-litres (a little over a pint) of sake or wine a day had lower intelligence quotients than those who did not drink at all,”Hiroshi Shimokata said.“Moderation is very important.”

If you were to eat more than 1800 calories per day,the surplus turns into fat.It takes about 3600 excess calories to make a pound of fat.Let"s say that you were to eat,on average,2000 calories per day.That extra 200 calories per day is going to turn into fat.However,you will eventually hit a point of equilibrium(平衡，均衡) because as you gain weight,you need more calories to maintain that weight.So,a person eating an average of 2000 calories per day will hit equilibrium at (2000/12) 166.67 pounds.
So let"s say that you eat,on average,2000 calories per day and reach equilibrium at 166 pounds.Then you go on a crash diet where you eat only 1000 calories per day for 60 days.You lose 16 pounds and reach your target weight of 150 pounds.But then you go right back to eating 2000 calories per day again.The graph below shows your eating pattern before,during and after the diet:
Note that the graph assumes that you,like most people,eat a random number of calories per day.Some days you are “good” and eat less,and some days you are “bad” and eat more,but the assumption is that it averages out to 2000 calories per day over the long run.
This graph shows what happens to your weight before,during and after the diet:
The diet really takes the weight off.But the weight comes right back when you return to your “normal” eating pattern.The weight appears to come back so quickly because when you are at your lightest,you tend to gain more weight each day.The lighter you are,the fewer calories you need.If you only need 1500 calories per day and you"re eating 2000,you"re going to gain weight faster than if you need 1800 and you"re eating 2000.
小题1:The passage is mainly about_________.
| A．how to lose weight effectively |
| B．why the weight comes back so quickly once a person stops dieting |
| C．why a person puts on weight |
| D．how to keep a healthy diet |
| A．1440 | B．1800 | C．2000 | D．1000 |
| A．A person who weighs 200 pounds. | B．A person who weighs 180 pounds. |
| C．A person who weighs 150 pounds. | D．A person who weighs 100 pounds. |
| A．Ways to keep the weight off. | B．Ways to go on a diet. |
| C．Diseases caused by overweight. | D．Proper diet to keep healthy. |
In one study,researchers in the United States examined information on more than 1000 people.The people had taken part in a long-term study of sleep disorders.
Some people slept less than five hours a night.They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less of the hormone leptin.Experts say ghrelin helps make people feel hungry;leptin makes you feel full.
The scientists say these hormonal changes may be a cause of obesity in Western societies.They note the combination that limitation is common and is widely available.
The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researchers say loss of sleep may increase hunger especially for high-calorie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep.
Researchers from Stanford University in California and the University of Wisconsin did the study.They found that the best amount of sleep for weight control is 7.7 hours a night.
The Public Library of Science published the findings in its journal Medicine.Internet users can read the full study,free of charge,at plos.org.
小题1:Which of the following shows the right way in which lack of sleep causes weight gain?
| A．more ghrelin and less leptin→feeling hungry→eating more |
| B．feeling hungry→eating more→more ghrelin and less leptin |
| C．burning more energy→feeling hungry→eating more |
| D．more leptin and less ghrelin→feeling full→less exercise |
| A．weight;sleep | B．sleep;food | C．hunger;food | D．weight;work |
| A．have your ghrelin level rise and leptin level drop |
| B．have your leptin level rise and ghrelin level drop |
| C．have your ghrelin and leptin levels properly balanced |
| D．feel neither hungry nor full |
| A．make a news report | B．offer a piece of medical advice |
| C．make an advertisement | D．keep a record of the research findings |
In the study,researchers had twenty women wear two pairs of shoes with three-inch heels,one with a narrow heel and the other with a thick one.The scientists compared how much pressure was put on the women’s knees by both types of shoes.The women also walked bare-foot to test normal pressure.The scientists found that both types of shoes applied equal amounts of pressure to the knees.Compared with walking barefoot,the heels increased pressure on the inside of the knee by 26 percent.Increased pressure on the knee eventually leads to arthritis,experts say.
The idea that high heels are bad for your health isn’t new—scientists have warned women for years that they contribute to problems ranging from corns to hammer toes,tendonitis,knee pain,sprained(扭伤)ankles and back problems.But in 1998,Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis,a painful joint disease that destroys cartilage(软骨)surrounding the knee.The first study looked only at stiletto heels,and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.“This study confirms what we all intuitively（直觉地）know that high-heeled shoes of any kind are not good for our health,”said Dr.Glem Pfeffer,a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.
小题1:We learn from the passage that women choose chunky heels because _________.
| A．they want to walk comfortably |
| B．chunky heeled shoes are cheaper than stiletto heeled pairs |
| C．chunky heels do less harm to knees |
| D．chunky heels are not painful at all |
| A．pressure on the foot is caused by high heels |
| B．the pressure is abnormal while walking barefoot |
| C．arthritis is always caused by pressure on the knees |
| D．both types of shoes have the same harm to the knees |
| A．people got to know the high heels are bad for health recently |
| B．people have known the high heels are bad for health for years |
| C．people haven’t known the high heels are bad for health yet |
| D．people will be warned that the high heels are bad for health soon |
| A．they feel more comfortable |
| B．they are related to knee osteoarthritis |
| C．they are worn by many women |
| D．they are different from stiletto heels |
| A．Talking Healthy Knees into Consideration |
| B．High-heels Do Harm to Knees |
| C．Chunky Heels and Stiletto Heels |
| D．When Wearing High-heels |
The number of survivors in need of food aid after the Indian Ocean disaster has climbed to 5 million people.They stretch from Somalia to Thailand,and the figure could rise further,the United Nations has said.
Relief teams hope to reach all of the estimated 700 000 hungry in Sri Lanka within three more days.It could take longer before enough food aid gets to the nearly 1 million people in need in hard-to-reach parts of Indonesia.Another serious problem is the need for purified water.
Although aid had poured in from all over the world to the disaster areas,“Logistics is the big problem here—just getting the stuff out to people who need it,”said Ron Libby,emergency management specialist at the USA agency for International Development.
Relief efforts are hindered by the difficulty of delivering aid to the more than 1000 islands scattered across hundreds of kilometers of ocean.
For those who survived the tsunami"s force,disease is now the No.1 problem.Five million people are short of water,food and basic sanitation across the region.World Health Organization(WHO) crisis chief David Navarro said 50 000 more people could die from disease and other causes,as has been the case in previous humanitarian emergencies.
WHO said it had already received a handful of reports of malaria(疟疾) and dengue fever(登革热) and hundreds of reports of diarrhea(腹泻) and infected wounds.It said millions of water purification tablets had been sent to Asia,along with sanitation engineers to rebuild water sanitation infrastructure.
Psychologists are warning that mental health problems caused by the tsunami could prove harder to resolve than the physical damage.
Some survivors say they are plagued by recurring nightmares about walls of water.Many locals are afraid to return to beachside homes.Officials also warn that suicide rates could rise dramatically as parents struggle with guilt at losing children.
Psychologists estimate that 20 to 30 per cent of people who face traumatic events eventually develop symptoms,such as alcohol abuse,lack of concentration at work and an inability to develop close relationships.
Although the Thai Government has offered to build temporary beachside housing,many refugee families are refusing to come down from the hills.Others are afraid to go back to jobs on the sea.
Over 150 000 people were killed by the tsunami,but hundreds and thousands more have been left with no means to earn a living.
In the village of Akirapettai in India,all that is left is the twisted wreckage of the fishing fleet.Dakshina Murti,a fisherman,not only lost three family members,but also lost his boats,his nets,everything.
“Everything"s gone,”he says.With no government aid so far,all he has is a wreck.There are several million people who suffered the same experience.Homes have been destroyed,as well as wharves,docks,and sheds.
For now,rebuilding the economy remains a distant concept.
小题1:This passage is mainly about _________that happened around the Indian Oceans.

| C．the sign of the tsunami | D．the warning of the tsunami |
| A．is not more than 5 million | B．is less than 5 million |
| C．has reached 5 million | D．won"t reach 5 million |
| A．disease | B．food | C．water | D．house |
| A．Dengue fever | B．diarrhea | C．Malaria | D．mental health problem |
She was transferred to a specialized hospital in the San Francisco Bay area.Whatever therapies could be applied to her case were used.The therapists were charmed by her undefeatable spirit.They taught her about imaging—about seeing herself walking.If it would do nothing else,it would at least give her hope and something positive to do in the long waking hours in her bed.Angela would work as hard as possible in physical therapy,in whirlpools and in exercise sessions.But she worked just as hard lying there faithfully doing her imaging;visualizing herself moving,moving,moving!
One day,as she was staining with all her might to imagine her legs moving again,it seemed as though a miracle happened:The bed moved!It began to move around the room!She screamed out,“Look what I’m doing!Look!Look!I can do it!I moved,I moved!”
Of course,at this very moment everyone else in the hospital was screaming,too,and running for cover.People were screaming,equipment was falling and glass was breaking.You see,it was the recent San Francisco earthquake.But don’t tell that to Angela.She’s convinced that she did it.And now only a few years later,she’s back in school. You see,anyone who can shake the earth between San Francisco and Oakland can conquer a piddling little disease,can’t they?

| A．The girl got over her disease just by imagining. |
| B．It was because of her strong determination and constant efforts that she got walking again. |
| C．The girl was on top of the world when she moved the bed in her room. |
| D．Doctors believe imagining being healthy helps patients recover. |
| A．where there is a will,there is a way |
| B．a person who is strong enough to shake the earth can get over any disease |
| C．just as it is impossible for one to shake the earth,so it is to conquer a serious disease |
| D．though one can shake the earth,he can’t defeat a little disease |
| A．Did The Earth Move For You? |
| B．A Miracle Made by a Young Girl |
| C．A Young Girl Conquered Disease |
