“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 ______.

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?
A.Children.B.Parents.C.Doctors.D.Researchers.

小題1:B
小題2:A
小題3:D
小題4:B

We know the effect calories have on your body.For each pound of weight that your body carries,it takes about 12 calories per pound per day to keep it alive.If you weigh 150 pounds,you therefore need about (150×12) 1800 calories per day to keep yourself alive and maintain that same weight.
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.
小題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
小題2:According to the text,a person weighing 120 pounds needs _________calories per day to keep the same weight.
A.1440B.1800C.2000D.1000
小題3:Suppose all the following people take in 3000 calories every day.Who will gain weight fastest?
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.
小題4:What will the writer continue to discuss at the end of the text?
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.

How can you find out what is going on inside a person' s body without opening the patient up? Regular X-rays can show a lot. CAT scans can show even more. They can give three-dimensional(三維) view of body organs(器官).
What is a CAT scan? CAT stands for Computerized Axial Tomography(層面X線照相術(shù)). It is a special X-ray machine that gets a 360 - degree picture of a small area of a patient's body.
Doctors use X-rays to study and examine diseases and injuries within the body. X-rays can find foreign objects inside the body or to take pictures of some organs inside if special things as dyes or special liquids are added to the organs to be X-rayed.
A CAT scanner, however, uses a beam(光束) of X-rays to give a cross-sectional view of a particular part of the body. A fine beam of X-rays is scanned across the body and circled around the patient from many different angles(角度). A computer analyzes(分析) the information from each angle and produces a clear cross-sectional picture on the screen. This picture is then photographed for later use. Several cross-sections, taken one after another, can give a clear "photo" of the entire body or of any body organs. The newest CAT scanners can even give a clear picture of active, moving organs just as a fast-action camera can "stop the action" giving clear pictures of what appear only mistily(模糊) to the eye. And because of the 360 - degree pictures, CAT scans show 3-dimensional views of organs in a manner that was once only seen during surgery or autopsy (examining a dead body).
小題1:According to the first two paragraphs, doctors can see the inside of a patient's body by ______.
A.giving the patient an operation
B.checking body organs
C.getting a 360-degree picture of a small area of a patient's body
D.examining the CAT
小題2:From the last paragraph, we can infer that ______.
A.the newest pictures become more misty
B.many pictures can be taken at the same time
C.the information about the scanned patient is not highly valued
D.some pictures of the scanned parts of the body are developed for further examinations in the future
小題3:The best title of this passage might be ______.
A.Modern X-rayB.Three-dimensional View
C.Fast - moving CameraD.CAT Scan

A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol(膽固醇)levels.
小題1:The passage is mainly about _________.
A.the high incidence of heart disease in some countries
B.the changes in people’s diet
C.the effect of fish eating on people’s health
D.the daily fish consumption of people in different cultures
小題2:We can infer from the passage that there are fewer heart disease deaths ________.
A.in countries of the yellow-skin race
B.in highly-developed countries
C.in the countries with high consumption of fish
D.in the countries with good production of fish
小題3:The phrase “this relationship” in paragraph 6 refers to the connection between _________ and the level of heart disease.
A.the amount of fish eatenB.regular fish-eating
C.the kind of fish eatenD.people of different areas
小題4:From the passage we know the author is most probably ______.
A.a(chǎn) heart doctorB.a(chǎn) science researcher
C.a(chǎn) supporter of healthy eatingD.a(chǎn) university student

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.
1.The medical article quoted in the first paragraph indicates            .
the way in which alcohol can help the heart      
how a couple of cocktails daily can stop heart problems
why alcoholic drinks are dangerous to one’s health 
that reports on the advantages of alcohol were misled
2.Experiments showed that nondrinkers had .
A.larger amounts of good cholesterol
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

  Exchange a glance with someone, and then look away. Do you realize that you have made a statement? Hold the glance for a second longer and you have made a different statement. Hold it for 3 seconds, and the meaning has changed again. For every social situation, there is a permissible time that you can hold a person’s stare without being friendly, rude, or aggressive. If you are on a lift, what stare-time are you permitted? To answer this question, consider what you typically do. You very likely give other passengers a quick glance to size them up and to assure them that you mean no harm. Since being close to another person signals the possibility of interaction, you need to send out a signal telling others you want to be left alone. So you cut off eye contacts. That is what sociologist Erving Goffiman calls “a dimming of the lights”. You look down at the floor, at the indicator lights, anywhere but into another passenger’s eyes. Should you break the rule against staring at a stranger on a lift, you will make the other person extremely uncomfortable, and you are likely to feel a bit strange yourself.
  If you hold eye contacts for more than 3 seconds, what are you telling another person? Much depends on the person and the situation. For instance, a man and a woman communicate interest in this manner. They stare at each other for about 3 seconds at a time, and then drop their eyes down for 3 seconds, before letting their eyes meet again. But if one man gives another man a 3-second-plus stare, he signals, “I know you”, “I am interested in you” or “You look peculiar and I am curious about you.” This type of stare often produces hostile feelings.
  60. It can be inferred from the first paragraph that ______.
  A. every glance has its significance
  B. a glance carries more meaning than words
  C. a stare longer than 3 seconds is unacceptable
  D. staring at a person is an expression of interest
  61. If you want to be left alone on a lift the best thing to do is ______.
  A. to look into another passenger’s eyes
  B. to keep a distance from other passengers
  C. to avoid eye contacts with other passengers
  D. to signal you don’t mean to do harm to anyone
  62. By “a dimming of the lights”, Erving Goffiman means ______.
  A. closing one’s eyes         B. turning off the lights
  C. stopping glancing at others     D. reducing stare-time to the minimum
  63. The passage mainly discusses ______.
  A. the limitations of eye contacts
  B. the exchange of ideas through eye contacts
  C. proper behavior in different situations in people’s daily life
  D. the role of eye contacts in communication between people

Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires—not that you cannot satisfy your tastes but that you don't have enough tastes.
Real riches consist of well-developed and hearty capacities (能力)  to enjoy life.  Most people are already swamped(淹沒) with things. They eat, wear, go and talk too much. They live in too big a house with too many rooms, yet their house of life is a hut.
Your house of life ought to be a mansion (豪宅) , a royal palace.  Every new taste, every additional interest, every fresh enthusiasm adds a room.  Here are several rooms your house of life should have.
Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry.
Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library.
Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.
Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the had days, if you could, and did, play a bit.
Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.
小題1:The author intends to tell us that____________.
A.true happiness lies in achieving wealth by fair means
B.big houses are people's most valued possessions
C.big houses can in a sense bring richness of life
D.true happiness comes from spiritual riches
小題2:The underlined sentence in the second paragraph probably implies that__________.
A.however materially rich, they never seem to be satisfied
B.however materially rich, they remain spiritually poor
C.though their house is big, they prefer a simple life
D.though their house is big, it seems to be a cage
小題3:It can be learned from the passage that __________.
A.more money brings more happiness
B.a(chǎn)rt is needed to make your house beautiful
C.literature can enrich your spiritual life

My daughter Allie is leaving for college in a week. Her room is piled with shopping bags filled with blankets, towels, jeans, sweaters. She won’t talk about going.
I say, “I’m going to miss you,” and she gives me one of her looks and leaves the room. Another time I say, in a voice so friendly it surprises even me: “Do you think you’ll take your posters and pictures with you, or will you get new ones at college?”
She answers, her voice filled with annoyance, “How should I know?”
 My daughter is off with friends most of the time. Yesterday was the last day she’d have until Christmas with her friend Katharine, whom she’s known since kindergarten. Soon, it will be her last day with Sarah, Claire, Heather... and then it will be her last day with me.
 My friend Karen told me, “The August before I left for college, I screamed at my mother the whole month. Be prepared.”
 I stand in the kitchen, watching Allie make a glass of iced tea. Her face, once so open and trusting, is closed to me. I struggle to think of something to say to her, something meaningful and warm. I want her to know I’m excited about the college she has chosen, that I know the adventure of her life is just starting and that I am proud of her. But the look on her face is so mad that I think she might hit me if I open my mouth.
 One night — after a long period of silence between us — I asked what I might have done or said to make her angry with me. She sighed and said, “Mom, you haven’t done anything. It’s fine.” It is fine — just distant.
 Somehow in the past we had always found some way to connect. When Allie was a baby, I would go to the day-care center after work. I’d find a quiet spot and she would nurse — our eyes locked together, reconnecting with each other.
 In middle school, when other mothers were already regretting the distant relationship they felt with their adolescent daughters, I hit upon a solution: rescue measures. I would show up occasionally at school, sign her out of class and take her somewhere — out to lunch, to the movies, once for a long walk on the beach. It may sound irresponsible, but it kept us close when other mothers and daughters were quarrelling. We talked about everything on those outings — outings we kept secret from family and friends.
 When she started high school, I’d get up with her in the morning to make her a sandwich for lunch, and we’d silently drink a cup of tea together before the 6:40 bus came.
 A couple of times during her senior year I went into her room at night, the light off, but before she went to sleep. I’d sit on the edge of her bed, and she’d tell me about problems: a teacher who lowered her grade because she was too shy to talk in class, a boy who teased her, a friend who had started smoking. Her voice, coming out of the darkness, was young and questioning.
 A few days later I’d hear her on the phone, repeating some of the things I had said, things she had adopted for her own.
 But now we are having two kinds of partings. I want to say good-bye in a romantic way. For example, we can go to lunch and lean across the table and say how much we will miss each other. I want smiles through tears, bittersweet moments of memory and the chance to offer some last bits of wisdom.
But as she prepares to depart, Allie has hidden her feelings. When I reach to touch her arm, she pulls away. She turns down every invitation I extend. She lies on her bed, reading Emily Dickinson until I say I have always loved Emily Dickinson, and then she closes the book.
Some say the tighter your bond with your child, the greater her need to break away, to establish her own identity in the world. The more it will hurt, they say. A friend of mine who went through a difficult time with her daughter but now has become close to her again, tells me, “Your daughter will be back to you.”
“I don’t know,” I say. I sometimes feel so angry that I want to go over and shake Allie. I want to say, “Talk to me — or you’re grounded!” I feel myself wanting to say that most horrible of all mother phrases: “Think of everything I’ve done for you.”
Late one night, as I’m getting ready for bed she comes to the bathroom door and watches me brush my teeth. For a moment, I think I must be brushing my teeth in a way she doesn’t approve of. But then she says, “I want to read you something.” It’s a brochure from her college. “These are tips for parents.”
I watch her face as she reads the advice aloud: “ ‘Don’t ask your child if she is homesick,’ it says. ‘She might feel bad the first few weeks, but don’t let it worry you. This is a natural time of transition. Write her letters and call her a lot. Send a package of candies...’ ”
Her voice breaks, and she comes over to me and buries her head in my shoulder. I stroke her hair, lightly, afraid she’ll run if I say a word. We stand there together for long moments, swaying. Reconnecting.
I know it will be hard again. It’s likely there will be a fight about something. But I am grateful to be standing in here at midnight, both of us tired and sad, toothpaste spread on my chin, holding tight to—while also letting go of—my daughter who is trying to say good-bye.
