For better eyesight, doctors advise limiting the hours of screen time and encourage having enough eye resting time.
However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia(近視). An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.
The research team found that the prevalence(流行)of myopia among children in Sydney was lower than children in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore.
Indoor and outdoor sports activities both make the eyes focus on more distant objects, which prevents the eyes from changing shape. But outdoor activities may better help avoid myopia than indoor sports activities.
Jane Gwiazda, who does research in sight problems, says: “Natural light is good for eye growth. And extra vitamin D from the sun might contribute to eye growth.”
Many doctors suggest that every child get its first eye test done when he/she is about two and half years old, and even if his/her sight seems perfect.
It is necessary for myopic children to wear glasses to prevent headaches, trouble reading or injuries. It is also important that schools invite doctors to test their students’ eyes.
If that is not possible, school teachers should at least encourage parents and children to have regular eye examinations and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors.

Narayana Hrudayalaya, a complex of health centers based in southern India, offers low-cost, high-quality specialty care in a largely poor country of 1.2 billion people. By thinking differently about everything from the unusually high number of patients it treats to the millions for whom it provides insurance, the hospital group is able to continually reduce costs. Narayana Hrudayalaya’s operations include the world’s largest and most productive cardiac (心臟病的) hospital, where the average open-heart surgery runs less than $2,000, a third or less what it costs elsewhere in India.

Narayana Hrudayalaya’s origins date back to 2001, when it built its massive cardiac center on the outskirts (市郊)of Bangalore. But it has expanded since then into what founder Dr. Devi Shetty calls a "health city," a series of centers specializing in eye, trauma, and cancer care. Narayana Hrudayalaya now manages or owns hospitals in 14 other Indian cities.

Expanding access is paired with a ongoing focus on efficiency. Typically, says Shetty, private hospitals in India focus on patients who can easily afford treatment. "We did it the other way around," he says. "This hospital is for poor people, but we also treat some rich people. We don’t look at people who are sgabbily dressed and have trouble paying as outsiders. "  Narayana Hrudayalaya’s flagship hospital has 3,000 beds and negotiates for better prices and buys directly from manufacturers, cutting out distributors.

In addition to cost-cutting, Narayana Hrudayalaya finds creative ways to make the economics work. The company started a micro-insurance program backed by the government that enables 3 million farmers to have coverage for as little as 22 cents a month in premiums(保險(xiǎn)費(fèi)). Patients who pay discounted rates are in effect compensated by those who pay full price

Doing something--doing more, actually--is the point. By 2017, Shetty, 58, plans to expand from 5,000 beds throughout India to 30,000. Before becoming one of India’s best-known health-care entrepreneurs, Shetty was its best-known heart surgeon. He was interrupted in surgery one day during the 1990s by a request to make a house call. "I said, 'I don’t make home visits,'?" Shetty says, "and the caller said, 'If you see this patient, the experience may transform your life.'?" The request was from Mother Teresa. Inspired by the her work with the poor, he then set out to create a hospital to deliver care based on need, not wealth.  "One lesson she taught me," he says, quoting a saying he keeps framed in his office, "is 'Hands that sew are holier than lips that pray.'?"

1.Narayana Hrudayalayastarted a micro-insurance to _______.

A.cut down on the cost of the treatment       B.get the support of the government

C.make the company run smoothly            D.a(chǎn)ttract more people to its hospital

2.We can infer from the passage that _______.

A.the cost of medicine care in India is very low

B.Shetty wouldn’t have succeeded without Mother Teresa

C.Shetty and his colleagues are likely to make home visits now

D.Shetty has expanded his hospitals to most of other cities in India

3.Why did Shetty build the massive cardiac center in 2001?

A.He wanted to build a health city.

B.He was motivated and decided to help more people.

C.He intended to develop his career in different areas.

D.He meant to help more poor people get free treatment.

4.How would you understand the underlined sentence in the last paragraph ?

A.It’s doing something and doing more that really matters.

B.It’s not easy to take positive action to contribute to society.

C.Healthcare workers are the holiest persons in the world.

D.Praying alone is of no significance in face of difficult situation.

C.

Here are two letters from our readers expressing their concern about school assessment (評(píng)價(jià)):

(l)

Students should be allowed to study without worrying about grades (學(xué)習(xí)成績(jī)). Fortunately, most educators realize that students have different interests and abilities. However, grade-based assessment is still very common. Grades often hold back creativity. Competing for better grades causes many students to turn down opportunities to go in for music, drama and sports. Grades are also an unfair measure of a student’s ability. I do not demand, as some extremists do, that grades should no longer be recorded. However, I do believe that less importance should be placed on. grades. I hope that someday grades will become optional(可選擇的) at Village High School.

Magdalena Smith, President

Drama Club

(2)

Let’s face the facts about grades. Grades perform three basic functions( 功能). First, grades get students to work at their highest level of competence  (能力 ). Second, they act as an encouragement for hard-working students and as a warming to those who are not. Finally, grades are an effective standard by which to measure students' achievement. Good grades help students to get jobs and to get into university.

I've spoken with a number of students who have jobs, and most of them say that they were hired mainly because of their grades. My grades helped me get a part-time job and will help me into university next year. I think grades are extremely important at Village High School.

The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.

Sometimes advertising is intentionally misleading. A few years ago a brand of

bread was offered to dieters (節(jié)食者) with the message that there were fewer calories in every slice. It turned out that the bread was not dietetic (適合于節(jié)食的), but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.

  On the positive side, emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.

  Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it? Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.

56. Advertising can persuade the consumer to buy worthless products by _________.

  A. stressing their high quality

  B. convincing him of their low price

  C. maintaining a balance between quality and price

  D. appealing to his buying motives

57. The reason why the bread advertisement is misleading is that ________.

  A. thin slices of bread could contain more calories

  B. the loaf was cut into regular slices

  C. the bread was not genuine bread

  D. the total number of calories in the loaf remained the same

58. The passage tells us that _______.

  A. sometimes advertisements really sell what the consumer needs

  B. advertisements occasionally force consumers into buying things they don’t need

  C. the buying motives of consumers are controlled by advertisements

  D. fire insurance is seldom a worthwhile investment

59. It can be inferred from the passage that a smart consumer should ________.

  A. think carefully about the benefits described in the advertisements

  B. guard against the deceiving nature of advertisements

  C. be familiar with various advertising strategies

  D. avoid buying products that have strong emotional appeal

60. The passage is mainly about ________.

  A. how to make a wise buying decision

  B. ways to protect the interests of the consumer

  C. the positive and negative aspects of advertising

  D. the function of advertisements in promoting sales

Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

    Psychologists have known that one person’s perception (知覺) of another’s “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping (打敗) evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses (假定), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form. The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

“We are grounded in our physical experiences even when we think abstractly,” says Bargh.

1. In Bargh’s experiment, the students were asked to _______.

  A. evaluate someone’s personality

  B. write down their hypotheses

  C. fill out a personal information form

  D. hold coffee and cold drink alternatively

2.We can infer from the passage that _______.

  A. abstract thinking does not come from physical experiences

  B. feelings of warmth and coldness are studied worldwide

  C. physical temperature affects how we see others

  D. capable persons are often cold to others

3.What would be the best title for the passage?

  A. Drinking for Better Social Relationships

  B. Experiments of Personality Evaluation

  C. Developing Better Drinking Habits

  D. Physical Sensations and Emotions
