Internet data shows that younger adults have become the primary audience obsessed with television programs about altering people’s appearance. Once the domain of the female in her fifties, plastic surgery has become the obsession of the younger Internet users.
The recent tragic death of Stephanie Kuleba, an 18-year-old high school cheer-leader who died as a result of a plastic surgery, brought our attention to the pursuit of a more "ideal" body amongst teenagers. In fact, search data confirms this phenomenon. One of the most popular sites visited from the search term "plastic surgery" is the official site of the American Society of Plastic Surgeons (www. plasticsurgery. org). Over 25% of visitors to the site fell within the 18-to-24-year-old—that’s up from 19.6% two years ago.
Plastic surgery has become an American obsession. Checking other markets, such as the U.K. and Australia, the 18-to-24-year-old fascination with plastic surgery is a definitely U.S. phenomenon. Looking at other health related sites visited by 18-to-24- year-olds reveals just how obsessed this age group is with appearance. Unlike the older groups who visit sites related to diseases and keeping healthy, younger Internet users flock to sites that dwell on personal appearance, such as those focused on body-building, weight loss and skin-care. And definitely plastic surgery.
While surgery-themed television may be driving the interest of a younger audience, one factor appears to be key in moderating teens from altering their bodies: the failing U.S. economy. If we track the trend in searches on topics such as "plastic surgery", there has been a sharp decline in all plastic surgery topics over the last year. It may very well be related to the noticeable income group of visitors—U.S. households that earn less than $30,000 per year. In fact, if we look at the search patterns around popular surgeries, over the last year the term "cost" appear most commonly.
While older age groups continue to search for information on procedures such as face-lifts or liposuction, it’s the younger Internet users who in tough economic times are focusing on improving their outer beauty, though at a discount price.
While young people are surfing on the Internet, they are very interested in ______.

A:how to be physically and mentally healthy B:how to make themselves look young C:how to prevent and cure diseases D:how to have more attractive appearance

Fire can help people in many ways. But it can be very dangerous. Fire can heat water, warm houses, give light and cook. But fire can bum things, too. It can bum trees, houses, animals or people. Sometimes big fires can burn forests.
Nobody knows for sure how people began to use fire. But there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope (绳子) and brought fire down.
Today people know how to make a rue with matches (火柴) . Children sometimes like to play with them. But matches can be very dangerous. One match can bum a piece of paper and then it might bum a house. A small fire can become a big fire very fast. Fire kills many people every year. So you must be careful with matches. You should also learn to put out rues. (80) Fires need oxygen(氧气). Without oxygen they will die. Cover a fire with water, sand, or sometimes with your coat. This keeps the air away from a fire and kills it. Be careful with fire, and it will help you. Be careless with fire, and it will burn you.

A:Not everybody knows how people began to use fire. B:Nobody knows how to make a fire. C:It is an Australian who started a fire. D:We are not sure how people began to use fir

Inevitably, as you try to make progress you will need the help of others. Getting this help may have less to do with your formal position and authority and more to do with your strategy and approach, which can range from a simple favor to convincing others to accept a priority of yours as if it were their own.
Define what needs to be done. Indistinct goals lead to indistinct results. By defining all the tasks required, you increase the likelihood of success. Be sure to include status reports and deadlines as you define specific action items that are needed.
Ask an individual for help. When you make a general request for volunteers during a meeting, colleagues often interpret it as "whoever doesn’t have much of anything to do can work on this". Your chances of getting someone to volunteer thus tend to be slim. However, if you think about who might best be able to help with a task and then specifically ask that person for help, your odds of getting him or her to accept the task increase dramatically.
Thank others for their assistance. Always thank and acknowledge others for their help. The person will feel that his or her time and energy were appreciated. In addition, you will likely be able to call on the person again in the future for assistance. But remember to return the favor when he or she needs your help. Such give-and-take behavior could lead to a valuable alliance.
Distribute your honor. If you’re congratulated for a job well done, let your supervisors know who helped you do it. Giving credit where credit is due will not only ingratiate (讨……欢心) you with your helper, but it will impress the bosses into considering you for future promotion. After alt, the best managers remain those who are best at getting others to help them complete their work for the common good.

A:how to get a promotion B:how to get others' help C:how to make a progress D:how to get along with the colleagues

Modern Drugs Doctors, sixty years ago, could do little to help victims of polio. Serious cases usually ended in death. In 1955, a vaccine was developed that prevented the disease. Today, polio is no longer a major health problem. Many of the most important drugs that doctors prescribe today have been developed in the last 30 years. Modern drugs are complex, specific and powerful. People need to know more about drugs in order to use them safely. Early people discovered by accident that some of the plants growing around them seemed useful to heal sores, relieve pain, or even cure diseases. These plants were the first drugs. Now plants are still the source of some drugs. Quinine, for example, is a bitter-tasting drug used to treat the chills and fever of malaria and to reduce attacks of the disease. It is made from the bark of the cinchona tree, which grows in the Andes Mountains. The Indians of that region were the first to use the bark as a medicine. The Spanish people probably brought it to Europe in the early 1600s. Chemists learned how to get the pure drug from the bark and in 1944; it was made artificially in the laboratory. Other important drugs, such as hormones and vaccines, are obtained from animals. But most of the modern drugs come from chemical combinations worked out by research scientists. Most people never see drugs in their simple form as chemicals. Instead, they are seen as tablets, capsules or liquids that contain the drug and other ingredients. People use drugs to get different results. Some drugs attack the organism that causes a disease. They cure by killing the organism. Other drugs relieve what we call the symptoms of the disease: the headache, pain, fever or chills, and make the patient more comfortable. These constitute most over-the-counter drugs. People can get them in drug stores. What is the main idea of this passage?

A:The development of modern drugs. B:How to make drugs. C:How to use drugs safely. D:The development of drugs.
