“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising good shapes and new look to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA (Food Drug Administration) can require proof under the Food, Drug and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually, Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
【小题1】It can be inferred that ads mentioned in the text are_____.

A.objectiveB.costlyC.unbelievableD.illegal
【小题2】The Relaxacisor is mentioned as______.
A.a product which was designed to produce electricity
B.a product whose distributor was involved in a legal case
C.a successful advertisement of a beauty product
D.an example of a quality beauty product
【小题3】The author intends to______.
A.make consumers aware of the promoters’ false promise
B.show the weakness of the law on product safety
C.give advice on how to keep young and beautiful
D.introduce the organization of FDA
【小题4】Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.
D. The promoters usually just care about profits.

Antidepressant(抗忧郁)drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin(血清素). Drugs such as Prozac are known as selective serotonin re-uptake inhibitors(or SSRIs). Their aim is to increase the level of this  “feel-good” chemical in the brain.

But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. “ We need to be much more cautious about use of these drugs,” says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada.

Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before.

“After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production,” he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years.

Most disturbingly of all, Andrews' review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs.

“Serotonin is an ancient chemical,” says Andrews. “It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm.”

Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews’ review highlights some important problems, yet it should also be taken with a pinch of salt. “This report is doing the opposite of what drug companies do,” he says. “Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews' study is useful in that it is always worth pointing out that there is a downside to any medicine. ” Professor Lightman adds that there is still a great deal we don't know about SSRIs-not least what they actually do in our brains.

When it comes to understanding why the drugs work only for a limited part of patients, U.S.  scientists think they might now have the answer. They think that in many depressed patients, it’s not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit.

URBANA, ILL. (AP)--Mike dropped out of college to support his pregnant(怀孕的) girlfriend and now works as a manager of a trucking company, Lynn graduated with honors from Harvard University and was hired as a lawyer with a top law firm in a major city. What do these two people have in common? Ten years ago they were both high school valedictorians (致告别辞者).

A University of Illinois study follows the lives of 81 valedictorians and salutatorians (致词的学生代表) who graduated a decade ago from public and private high schools in the state.

Tales of Success and Failure

The study found tales of success and failure. The research on 46 women and 35 men found that some were doctors and scientists, one was a drug addict, another was a waitress with emotional problems.

"There is a popular idea about people who do well in school doing well in life," said Terry Denny, professor of education. Denny conducted the study with Karen Arnold, a former graduate student of Denny' s who is now a professor at Boston College. Denny and Arnold contacted the 81 students before graduation, and then followed up with interviews nearly every other year. They also sent them questionnaires in the mail.

Varied Careers

One-third of the students are lawyers, or have a doctorate. Nineteen are in business and 15 are engineers or computer scientists. Others include a farmer, a stock broker, and an aerobics instructor.

Arnold says many of the students have only average positions in the work world and that "most are not headed for greatness in their careers." Denny, however, says that it is too early to make such predictions. "Who expects someone to be on the Supreme Court at the age of 28 or to be the discoverer of an important scientific invention right after college?" he said. "These students are just getting started in life. They are just beginning to find out what life is all about."

1.What can we conclude from Paragraph 1?

A.Mike got married before he went to college.

B.Lynn was honored by a law firm in the city.

C.Mike was not so lucky as Lynn after graduating from college.

D.Mike and Lynn both graduated first in their high school class.

2.According to the article Denny is probably older than Arnold because      .

A.Denny was her professor

B.Arnold did well at school.

C.Denny interviewed some students

D.Arnold helped Denny in the research

3.What is probably the best title for the article?

A.Successful Careers for College Graduates

B.Success in Education Predicts Success in Later Life

C.High School Honors Not Always Key to Life Success

D.A study on Successful Jobs and College Graduates

4.Who probably wrote this article?

A.College graduates

B.Reporters

C.Professors and researchers

D.Teachers
