For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs, coupled with the aging of the baby-boom generation, a longer life span means that the nation's elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995. The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions, and in law and business as well. "In addition to the doctors, we're going to need more sociologists, biologists, urban planners and specialized lawyers," says Professor Edward Schneider of the University of Southern California's (USC) School of Gerontology (老年學(xué)).

Lawyers can specialize in "elder law," which covers everything from trusts and estates to nursing-home abuse and age discrimination (歧視). Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. "Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money," one professor says.

Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was "really bored with bacteria." So she took a class in gerontology and discovered that she liked it. She says, "I did volunteer work in retirement homes and it was very satisfying."

1."...Old is suddenly in" (Line 1, Para. 1) most probably means "________".

A. America has suddenly become a nation of old people

B. gerontology has suddenly become popular

C. more elderly professors are found on American campuses

D. American colleges have realized the need of enrolling older students

2.With the aging of America, lawyers can benefit ________.

A. from the adoption of the "elder law"

B. from giving special services to the elderly

C. by enriching their professional knowledge

D. by winning the trust of the elderly to promote their own interests

3.Why can businessmen make money in the emerging elder market?

A. Retirees are more generous in spending money.

B. They can employ more gerontologists.

C. The elderly possess an enormous purchasing power.

D. There are more elderly people working than before.

4.Who can make big money in the new century according to the passage?

A. Retirees who are business-minded.

B. The volunteer workers in retirement homes.

C. College graduates with an MBA or law degree.

D. Professionals with a good knowledge of gerontology.

5.It can be seen from the passage that the expansion of America's elderly population ________.

A. will provide good job opportunities in many areas

B. will place an unbearable burden on society

C. may lead to nursing home abuse and age discrimination

D. will create new fields of study in universities

Today, we know that the role of vitamins and minerals goes way beyond the prevention of deficiency diseases (維生素缺乏癥) to actually preventing cancer and heart disease, the most fearsome killers of our time. With this knowledge has come the widespread call for nutritional supplementation (營(yíng)養(yǎng)補(bǔ)充) — and a confusing group of vitamin, mineral, and supplements lining the supermarket shelves.

Far from contributing to better health, however, nutritional supplements threaten to turn a scientific breakthrough into a nutritional disaster.

Promoters of vitamins and minerals — especially vitamins A, C, and E— would have consumers believe that the little vitamin pill in the bottle is all they need for good health. Take your vitamins in the morning, and you’re covered. It’s okay to eat fast foods for the rest of the day or skip meals to achieve today’s fashionably skinny look. But vitamins and minerals are only one part of the nutritional puzzle. A diet rich in fiber (纖維) and balanced in carbohydrates and protein is essential for good health. You can’t get these things from a nutritional supplement. The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek.

And no supplement can compare to the quality of nutrition found in natural sources. For example, our bodies turn carotenes (胡蘿卜素) from plant foods into vitamin A. Many supplements contain a single carotene, but natural sources are rich in many different carotenes. Many supplements contain a form of vitamin E that is made from chemicals, when natural vitamin E is more readily absorbed and used by the body. And science is still discovering the wealth of nutrients in foods.

You’d be hard-pressed to find a supplement as nutritionally comprehensive and powerful as a balanced diet. Even if you could, you’d pay much more than if you got the same nutritional value from natural sources.

But perhaps the greatest danger presented by nutritional supplements comes from the very real risks presented by self-medication. Anyone can walk into the market and buy as many different supplements as desired. The reported benefits of high dosages of certain nutrients have led some people to believe that the more the better. Many take several vitamin and mineral supplements without regard to possible consequences.

Surprising new research suggests that vitamin C pills may speed up hardening of the arteries, the underlying cause of heart attacks. Researchers said their findings support the recommendations of health organizations, which urge people to avoid high doses of supplements and to get their nutrients from food instead.

As appealing as they’re made to sound, nutritional supplements are danger in disguise. If you’re looking for good health, don’t look on the supplement shelves of your supermarket. Look in the produce section instead.

1.What has given rise to the great need for nutritional supplements?

A. The knowledge of deficiency diseases.

B. The low prices of nutritional supplements.

C. The frighteningly high death rate from cancer and heart disease.

D. The information about the role of vitamins and minerals in health.

2.The “promoters” (Paragraph 3) most probably refers to ________.

A. businessmenB. doctorsC. scientistsD. fast food lovers

3.According to the passage, nutritional supplements ________.

A. are made from chemicals

B. are ineffective in supplying fiber

C. provide too much vitamin C

D. contain a kind of dangerous carotene

4.By describing nutritional supplements as “danger in disguise” in the last paragraph, the writer means that they are ________.

A. of little help

B. of poor quality

C. potentially harmful

D. extremely poisonous

Doing well in high school prepares students for life in college and beyond, so achieving student success is important. High school students learn valuable information from class lectures and homework, and by asking for help when it is needed. Being prepared for tests and engaging in school activities can help a student to achieve success in high school.

Complete any homework you are assigned on time. Then, if you need help understanding a concept you will have plenty of time to get help.

Create a study area in your home. This can be a quiet bench outside or a seating area in your room. If you like to listen to music while studying, listen to classical or relaxing music. Be sure to have plenty of lighting in the area to read your textbook or notes.

Keep a schedule. If you have extra-curricular activities like sports or school meetings, make sure to schedule your homework and study time around them. Keeping a schedule will allow you to get better grades while they are having fun in high school.

Eat breakfast. Having breakfast each morning before school will give you energy and brain function to pay better attention in class. Eat snacks during study sessions to keep alert and focused on your work.

Create a study group to help fellow high school students and get help if you need it. Studying with others will help reinforce concepts and information, and if you need help there will always be someone there to help you before you get behind in your studies.

Set up after-school hours with your teacher if you need extra tutoring. Visiting a teacher for one-on-one time before a test will help you nail down those last few concepts you need help with.
