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.

Apartado 519 Panama, Republica de Panama June, 2002Customer Relations Dept.Univox Audio Systems, Inc.7789 Grove Blvd.Palo Alto, CA 94302Dear Sir / Madam, I’m writing to you concerning a Univox CD player(Model CDP4500) that I purchased several months ago from one of your dealers (经销商) here in Panama City: Discount Audio. From your ads, I was led to believe that your audio equipments are the best available on the market. That’s hard to believe, considering that I’ve had nothing but problems with my CD player from the day I bought it. For one thing, the tracking (跟踪) mechanism doesn’t work properly; I can never tell for sure what part of the CD is playing. And now there’s a problem with the volume(音量) control; sometimes it works and sometimes it doesn’t. I took the player to the service department at Discount Audio. When I picked it up, they said they’d fixed the tracking mechanism as best they could, but it still doesn’t work properly. I’m sick and tired of all the problems I’ve had with your product. I hope you will understand my concern. I look forward to hearing from you about what you can do to help solve this problem. Faithfully yours, Roberto Suarez What was the first problem he had The ______ didn’t work well.

Interview The importance and focus of the interview in the work of the print and broadcast journalist are reflected in several books that have been written on the topic. Most of these books, as well as several chapters, mainly in, but not limited to, journalism and broadcasting handbooks and reporting texts, stress the "how to" aspects of journalistic interviewing rather than the conceptual aspects of the interview, its context, and implications. Much of the "how to" material is based on personal experiences and general impressions. As we know, in journalism as in other fields, much can be learned from the systematic study of professional practice. Such study brings together evidence from which broad generalized principles can be developed. There is, as has been suggested, a growing body of research literature in journalism and broadcasting, but very little significant attention has been devoted to the study of the interview itself. On the other hand, many general texts as well as numerous research articles on interviewing in fields other than journalism have been written. Many of these books and articles present the theoretical and empirical (经验的) aspects of the interview as well as the training of the interviewers. Unhappily, this plentiful general literature about interviewing pays little attention to the journalistic interview. The fact that the general literature on interviewing does not deal with the journalistic interview seems to be surprising for two reasons. First, it seems likely that most people in modem Western societies are more familiar, at least in a positive manner, with journalistic interviewing than any other form of interviewing. Most of us are probably somewhat familiar with the clinical interview, such as that conducted by physicians and psychologists. In these situations the professional person or interviewer is interested in getting information necessary for the diagnosis and treatment of the person seeking help. Another familiar situation is the job interview. However, very few of us have actually been interviewed personally by the mass media, particularly by television. And yet, we have a vivid acquaintance with the journalistic interview by virtue of our roles as readers, listeners, and viewers. Even so, the understanding of the journalistic interview, especially television interview, requires thoughtful analyses and even study, as this book indicates. The passage is most like a part of a journalistic interview.
