题型：不详难度：来源：
Our sense of smell, which we normally take for granted, is nowadays being increasingly used for purposes which might surprise us if we realized them.
One area in which smells are created to achieve particular results is marketing. For some time producers have taken advantage of our sense of smell with regard to household goods.
When pleasant smells are passed through a store’s air conditioning system, people tend to spend more time in the store and buy more. For example, the smell of chocolate is used in sweet stores, while the smell of leather and perfume are used in clothes stores.
In a test, people looked at the same types of shoes in two rooms—one filled with purified air, the other with a smell of mixed flowers. Eighty-four percent of the people preferred the shoes in the room with the smell of flowers. In fact, many said they would have paid up to US $ 10 more for a pair.
Smells also have other uses. Research has shown that certain smells can help to calm anxious people and increase their feeling of safety. Smells such as that of flowers and pine forests might therefore be used to relax patients in doctors’ and dentists’ waiting rooms, and to make the environment more pleasant and less stressful to them.
Some companies are experimenting with different smells to produce different efferent effects on their workers according to the time of day.
For example, early in the morning they might put the smell of lemon in the air conditioning system to wake people up. In the middle of the morning, when the atmosphere tends to become more tense, the smell of wood could be used to calm people down. Before lunchtime the smell of melting butter would encourage people to go to lunch on time. After lunch, when people often begin to lose attention, the smell of mint would increase their watchfulness.
While some of these uses of smells may e helpful and effective, not everyone would agree with their use to control customers in stores. It has been suggested by consumers’ organizations that one way to avoid this new subconscious（无意识）pressure to buy is to go shopping when people are less likely to be influenced by smells.

Not so long ago, if you avoided drinking water during a workout（训练）, you were considered tough. Today, most experts 36 , you would be considered unintelligent.
Even in you don’t sweat much or feel 37 and even if there is a nice breeze, 38 experts say drinking water- or something 39 is necessary before, during and after all warmer-weather 40 .
Only a few years ago, many coaches 41 players from drinking anything during the game----they thought it was 42 for them to rinse(漱口) their mouths, 43 swallowing anything might slow them down.
Now, there’s 44 plenty of water on the sidelines for athletes to drink. The National Hockey League even 45 goalkeepers to put water bottles on top of their nets.
These new practices 46 be lost on the recreation(消遣) athlete. Some 47 advise you to drink about two cups of water 15 minutes or so after you 48 exercising and the same amount every 15 minutes. In some types of exercises-running, for example-others encourage drinking a cup or two of water 49 the workout.
Don’t drink any more, experts say too much fluid makes 50 and exercise uncomfortable. In 51 continuous hot-weather exercise, 52 can sweat and breathe away 1.8 kilograms of 53 an hour.
Drinking water does two things: restore some 54 and allow you to keep sweating so the skin can be kept 55 . Doctors say drinking six or eight cups a day can help digestion.

If you"re 70 and overweight, you may live longer
A few extra pounds might help you live longer if you"re past your prime(壮年) but otherwise healthy, a new study finds.
Physicians routinely follow guidelines issued by the World Health Organization. Because weight depends on height, they use a standard measure called body mass index (BMI), which is calculated as the weight in kilograms divided by the height in meters squared.
Healthy weight is defined as a BMI anywhere between 18.5 and 24.9 in adults, whereas 25 to 29.9 is overweight and 30+ is obese.
The new study suggests that in the elderly, these boundaries may be too narrow. While no one is questioning that extra fat poses health risks in young and middle-aged adults, it may reduce the impact of frailty and old age, geriatrician(老年医学专家) Dr. Thomas Yoshikawa told Reuters Health.
So far, nobody knows exactly how BMI affects lifespan in older people. Some researchers speculate that it acts as an energy reserve that can help the elderly cope with illness.
For the study, Australian researchers followed more than 9,000 men and women who were between 70 and 75 years old at the beginning. The participants reported their height and weight as well as various factors related to health and lifestyle. About 33 percent of the women and 44 percent of the men were overweight.
Over 10 years, more than 2,000 of the participants died. Women who had an active life and didn"t smoke were the most likely to be alive at the end of the study.
But neither health nor lifestyle could fully explain why overweight people of both sexes survived longer than their normal-weight peers, who fared no better than obese individuals. In terms of survival, the best BMI was between 26 and 27, well within the overweight range.
The new results agree with earlier research showing that fat may be beneficial in old age.
1．We can learn from the passage that_________．
A. the heavier one is, the better
B. we shouldn’t lose weight when old
C. one should keep his weight within the recommended range
D. we shouldn’t worry about our weight if we are slightly fatter than normal when old
2．According to the passage, if a person is 1.5 metres in height and 67.5 kg in weight, his BMI is________.
A．30 B．25 C．45 D． 28
3. What does the author want to tell us most?
A. Fatness has little to do with diseases in old age.
B. Fatness is not always bad.
C. Fatness may be beneficial instead of harmful in old age.
D. Overweight people of both sexes survive longer than their normal-weight peers.

In the college-admissions wars, we parents are the true fighters. We’re pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice. I’ve twice been to the wars, and as I survey the battlefield, something different is happening. We see our kids’ college background as a prize demonstrating how well we’ve raised them. But we can’t acknowledge that our obsession(痴迷) is more about us than them. So we’ve created various justifications（辩解）that turn out to be half-truths, prejudices or myths. It actually doesn’t matter much whether Aaron and Nicole go to Stanford.
We have a full-developed panic; we worry that there won’t be enough prizes to go around. Fearful parents urge their children to apply to more schools than ever. What causes the hysteria(歇斯底里) is the belief that scarce elite（精英）degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All seems right but mostly wrong. We haven’t found any convincing evidence that selectivity or prestige matters. Selective schools don’t systematically employ better instructional approaches than less selective schools. On two measures—professors’ feedback and the number of essay exams selective schools do slightly worse.
By some studies, selective schools do enhance（提高） their graduates’ lifetime earnings. The gain is reckoned at 2-4% for every 100-point increase in a school’s average SAT scores. But even this advantage is probably a statistical fluke(偶然). A well-known study examined students who got into highly selective schools and then went elsewhere. They earned just as much as graduates from higher-status schools.
Kids count more than their colleges. Getting into Yale may signify intelligence, talent and ambition. But it’s not the only indicator and, surprisingly, its significance is declining. The reason: so many similar people go elsewhere. Getting into college is not life’s only competition. In the next competition—the job market and graduate school—the results may change. Princeton economist Alan Krueger studied admissions to one top Ph.D. program. High scores on the GRE helped explain who got in; degrees of famous universities didn’t.
So, parents, take it easy（lighten up）. The stakes (利害关系) have been vastly exaggerated. Up to a point, we can rationalize our pushiness. America is a competitive society; our kids need to adjust to that. But too much pushiness can be destructive. The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment. One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction. They may have been so conditioned to being on top that anything less disappoints.
1. Why does the author say that parents are the true fighters in the college-admissions wars?
A. They have the final say in which university their children are to attend.
B. They know best which universities are most suitable for their children.
C. They have to carry out intensive surveys of colleges before children make an application.
D. They care more about which college their children go to than the children themselves.
2. Why do parents urge their children to apply to more schools than ever?
A. They want to increase their children’s chances of entering a prestigious college.
B. They hope their children can enter a university that offers attractive scholarships.
C. Their children will have a wider choice of which college to go to.
D. Elite universities now enroll fewer student than they used to.
3. What does the author mean by “kids count more than their colleges” Line1, para.4?
A. Continuing education is more important to a person’s success.
B. A person’s happiness should be valued more than their education.
C. Kids’ actual abilities are more important than their college background.
D. What kids learn at college cannot keep up with job market requirements.
4. What does Krueger’s study tell us?
A. Getting into Ph.D. programs may be more competitive than getting into college.
B. Degrees of prestigious universities do not guarantee entry to graduate programs.
C. Graduates from prestigious universities do not care much about their GRE scores.
D. Connections built in prestigious universities may be kept long after graduation.
5. One possible result of pushing children into elite universities is that______
A. they earn less than their peers from other institutions
B. they turn out to be less competitive in the job market
C. they experience more job dissatisfaction after graduation
D. they overemphasize their qualifications in job application
