Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, s ay, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in suport of that theory. More important, the work provided the first solid indiction of how alcohol works to protect the heart.In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvard Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection: those who drank alcohol had higher blood levels of high?density lipoproteins, the so?called good cholesterol, which is known to prevent heart disease.
As evidence has mounted, some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to reommend a regular happy hour for everyone. The risks of teetotalling(絕對(duì)戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles—not to mention violent behaviour and traffic accidents. Moreover, some studies suggest that even  moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of a daily dose of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighbourhood bar or liquor store.

that reports on the advantages of alcohol were misled
2.Experiments showed that nondrinkers had .

B.smaller amounts of good cholesterol
C.higher blood pressure
D.lower blood pressure
3.According to the passage, moderate drinking            .
is recommended by most doctors for heart patients    
should be allowed on prescription
is still not medically advisable                     
is not related to liver problems
4.The main theme of this passage is .
the change in recent drinking habits                
the connection between cancer and alcohol
whether moderate drinkers outlive nondrinkers       
whether alcohol may be good for one’s health

1.  第一段第一句是一個(gè)問題,第二句是對(duì)這個(gè)問題的回答。然后在第三句話中作者又引用了新英格蘭醫(yī)學(xué)雜志上的一篇文章來進(jìn)一步支持這一理論,故B為正確答案。
2.  作者在第二段中先對(duì)實(shí)例進(jìn)行對(duì)比。在本段最后一句指出,明顯的保護(hù)源是飲酒者的高密脂蛋白中的含量更高,即所謂的好的膽固醇高,可抑止心臟病。由此推知不飲酒者的“好的膽固醇少”,這正是B的內(nèi)容。
3.   由最后一段可知,即使是適當(dāng)飲酒,也有兩種不同的態(tài)度:有些醫(yī)生建議心臟病患者每天喝上一點(diǎn),可大多數(shù)醫(yī)生并不準(zhǔn)備這么做。此外,有的研究報(bào)告指出適當(dāng)飲酒可能增加乳房和結(jié)腸癌的患病率。由此可知,C為正確答案。
4.  全文主要說明飲酒是否對(duì)健康有好處。

Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only pretty, but NASA scientists are finding them to be surprisingly useful in absorbing possible harmful gases and cleaning the air inside modern buildings.?
NASA have announced the finds of a 2-year study that suggested the common indoor plants may provide a natural way of helping fight against “Sick Building Syndrome(綜合癥)”.?
Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wloverton, a senior research scientist at NASA. ?
Based on preliminary evaluations(初步評(píng)估) of the use of common indoor plants for indoor air purification(凈化),NASA funded a study using about a dozen popular varieties of attractive plants to determine their effectiveness in removing several key pollutants linked with indoor air pollution. NASA research on indoor has found that living plants are so efficient at absorbing pollutants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations.?
While more research is needed, Wolverton says the study has shown that common indoor plants can remove certain pollutants from the indoor environment. “We feel that future results will provide an even stronger argument that common indoor plants can be a very effective part of a system used to provide pollution free homes and work places,” he concludes.?
“Combining nature with technology can increase the effectiveness of plants in removing air pollutants,” he said.
NASA research has always shown that living, green and flowering plants can remove several poisonous chemicals from the air inside buildings. You can use plant in your home or office to improve the quality of the air to make it a more pleasant place to live and work—where people feel better, perform better, and enjoy life more.
小題1:The main idea of the passage is _______.?
A.plants are very useful to human beings?

  Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind.
All foods including water — cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean (瘦的) meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is controlled.
Nowadays most foods are dried mechanically. The conventional method of such dehydration (脫水) is to put food in chambers (室) through which hot air is blown at temperature of about ll0'C at entry to about 43'C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated steel cylinder (圓筒), then put them into a chamber through which a current of hot air passes. In the first process, the dried material comes off the roller (滾筒) as a thin film which is then broken up into small, though still relatively flakes (薄片). In the second process it falls to the bottom of the chamber as small powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients (成分) are dried separately and then mixed.
Dried foods take up less room and weigh less than the same food packed in cans or
frozen, and they do not need to be stored in special conditions. For these reasons they
are invaluable to the climbers, explorers and soldiers in battle, who have little storage
space. They are also popular with housewives because it takes so little time to cook
them.
小題1:It can be inferred from the passage that ________.
A.the rattier fish contain as much water as the lean one
B.the rattier the fish is, the more water it may contain
C.a(chǎn) fatty fish holds less water than a lean one
D.the water content of fish has nothing to do with the content of their fat
小題2: The underlined word "conventional" in Paragraph 3 can most probably be replaced by _________.
A.particularB.scientificC.usualD.special
小題3:Which of the following statements is NOT true about drying food?
A.The removal of water in food helps prevent it from going rotten.
B.The open-air method of drying food has been known for hundreds of years.
C.In the course of dehydration, the temperature of hot current coming from entry to exit is gradually going up.
D.The process of drying liquids is much more complex than that of drying solid food.
小題4:The last paragraph mainly talks about __________.
A.the reason why housewives like dried food
B.the general convenience of dried food
C.the methods of storing food
D.the advantages of dried, canned and frozen food

“Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity,” researchers recently reported in the journal Hypertension.
“Sugar-sweetened soft drinks are a significant source of calorie intake in children,” said Feng J. He, a researcher at St George’s University of London, England. “It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people.” They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption.
Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. “We found that children eating a lower-salt diet drank less fluid,” said He. “From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day.”
The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. “If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week,” Dr He said.
In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. “Both high blood pressure and obesity increase the risk of having strokes and heart attacks,” Dr He said.
Dr He recommends that parents check labels and choose low-salt food products. “Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors (感受器) and do not cause any technological or safety problems,” Dr He said.
小題1:According to the passage, obesity is directly linked to ______.
A.high-salt foods
B.sugar-sweetened soft drinks
C.high blood pressure
D.strokes and heart attacks
小題2:Compared with previous studies, the recent one found that ______.
A.a(chǎn) lower-salt diet may mean less sugar-sweetened soft drink consumption
B.a(chǎn) low-salt diet keeps children out of high blood pressure
C.children face the risk of having strokes and heart attacks
D.low-salt food products do not do harm to people’s health
小題3:Which of the following statements would Dr He agree to?
A.The less salt people eat, the healthier people become.
B.Children should reduce fluid intake in their daily life.
C.No high-salt food products will be available in shops.
D.A low-salt diet may prevent both high blood pressure and obesity.
小題4:After reading the passage, who should take effective action?

Remember how great exercise was when you were a little kid? Back then, racing around the playground or skipping rope for hours, you weren’t thinking fitness, you were thinking entertainment. But in this age of high-tech home equipment and underused gym memberships, the simple joy of jumping rope has been forgotten, Rediscovering it will give you a total-body exercise you can find.
Although considered an excellent form of exercise, jumping rope has never gained widespread acceptance because of two fundamental reasons. First, most people recognize jumping rope as an excellent form of cardiovascular(心血管的)exercise, but they also believe that it is simply too difficult. In other words, they don’t think they’ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical outcome. Second, many view it as somewhat boring and overly repetitive not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun if you find a proper way to practice it. Instead of doing the usual two-foot bounce over and over again, people good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double-bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping.
Now researchers are learning that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres to perform in parallel to each other. In short, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life.
61. From the first paragraph we learn that_________.
A. jumping rope has faded from people’s memories
B. people now have more advanced equipment
C. racing around the playground was preferred
D. people now like to have exercise in a gym
62.Rope jumping has not spread widely because_________.
A. it benefits the cardiovascular system
B. it is neither easy nor enjoyable
C. it is considered boring and repetitive
D. it requires little equipment, time and space
63.The first sentence in the 3rd paragraph implies_________.
A. there is only one proper way to follow
B. the usual way should not be used
C. the easiest way is always the best
D. there are many ways to follow
64.According to the researchers, jumping rope_________.
A. only prepares the brain for learning
B. is suitable for students only
C. helps both brain hemispheres work together
D. can be dangerous for old people
65.What is the author’s attitude towards rope jumping?
A. He is arguing against it
B. He is in favor of it
C. He is sitting on the fence of it
D. He is not clear about it
