Working MothersCarefully conducted researches that have followed the children of working mothers have not been able to show any long-term problems, compared with children whose mothers stayed at home.

Medical JournalsMedical journals are publications that report medical information to physicians and other health professionals.In the past, these journals were available only in print. With the development of electronic publishing, many medical journals now have Web sites on the Internet, and some journals are published only online. A few medical journals, likethe Journal of the American Medical Association, are considered general medical journals because they cover many fields of medicine. Most medical journals are specialty journals that focus on a particular area of medicine.Medical journals publish many types of articles. Research articles report the results of research studies on a range of topics varying from the basic mechanisms of diseases to clinical trials that compare outcomes of different treatments. Review articles summarize and analyze the information available on a specific topic based on a careful search of the medical literature. Because the results of individual research studies can be affected by many factors, combining results from different studies on the same topic can be helpful in reaching conclusions about the scientific evidence for preventing, diagnosing or treating a particular disease. Case conferences and ease reports may be published in medical journals to educate physicians about particular illnesses and how to treat them. Editorials in medical journals are short essays that express the views of the authors, often regarding a research or review article published in the same issue. Editorials provide a perspective on how the current article fits with other information on the same topic. Letters to the editor provide a way for readers of the medical journal to express comments, questions or criticisms about articles published in that journal. Letters to the editor enable readers of a medical journal to express comments on ______.
A. any medical event
B. articles published in the same issue
C. articles published in that journal
D. medical development
Adult Education1 Voluntary learning in organized courses by mature men and women is called adult education. Such education is offered to make people able to enlarge and interpret their experience as adults. Adults may want to study something which they missed in earlier schooling, get new skills or job training, find out new technological developments, seek better self-understanding, or develop new talents and skills.2 This kind of education may be in the form of self-study with proper guidance through the use of libraries, correspondence courses, or broadcasting. It may also be acquired collectively in schools and colleges, study groups, workshops, clubs, and professional associations.3 Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution. Great economic and social changes were taking place: people were moving from rural areas to cities; new types of work were being created in an expanding factory system. These and other factors produced a need for further education and reeducation of adults.4 The earliest programs of organized adult education arose in Great Britain in the 1790s, with the founding of an adult school in Nottingham and a mechanics institute in Glasgow. The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Philadelphia in 1727.5 People recognize that continued learning is necessary for most forms of employment today. For example, parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs. Adult education programs are springing up constantly to meet these and other needs. Paragraph 4 ______
Preserving Nature for FutureDemands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe. Studies by the Council of Europe, of which 21 countries are members, have shown that 45 percent of reptile (爬行类的) species and 24 percent of butterflies are in danger of dying out.European concern for wildlife was outlined by Dr. Peter Baum, an expert in the environment and natural resources division of the council, when he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the council"s diploma for nature reserves of the highest quality, and Dr. Peter Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks, and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a strong supporter of the view that natural environment needed to be allowed to survive in peace in their own right."No area could be expected to survive both as a true nature reserve and as a tourist attraction, "he went on. The short-sighted (眼光短浅的) view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future."We forget that they are the guarantee of life systems, on which any built-up area ultimately depends," Dr. Bantu went on, "we could manage without most industrial products, but we could not manage without nature. However, our natural environment areas, which are the original parts of our countryside, have shrunk to become mere(纯粹的) islands in a spoiled and highly polluted land mass." Recent studies by the council of Europe have indicated that ______.
A. wildlife needs more protection only in Britain
B. all species of wildlife in Europe are in danger of dying out
C. there are fewer species of reptiles and butterflies in Europe than elsewhere
D. many species of reptiles and butterflies in Europe need protecting
The Dangers of Second-hand SmokeMost people know that cigarette smoking is harmful to their health. Scientific research shows that it causes many kinds of diseases. In fact, many people who smoke get lung cancer. However, Edward Gilson has lung cancer, and he has never smoked cigarettes. He lives with his wife Evelyn, who has smoked about a pack of cigarettes a day throughout their marriage. 1 No one knows for sure why Mr. Gilson has lung cancer. Nevertheless, doctors believe that second-hand smoke may cause lung cancer in people who do not smoke because nonsmokers often breathe in the smoke from other people"s cigarettes. 2 The US Environmental Protection Agency reports that about 53,000 people die in the United States each year as a result of exposure to second-hand smoke.The smoke that comes from a lit cigarette contains many different poisonous chemicals. In the past, scientists did not think that these chemicals could harm a nonsmoker"s health. 3 They discovered that even nonsmokers had unhealthy amounts of these toxic chemicals in their bodies. As a matter of fact, almost all of us breathe tobacco smoke at times, whether we realize it or not. For example, we can not avoid second-hand smoke in restaurants, hotels and other public places. Even though many public places have nonsmoking areas, smoke flows in from the areas where smoking is permitted.It is even harder for children to avoid second-hand smoke. 4 Research shows that children who are exposed to second-hand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as are children of nonsmokers. The risk is even higher for children who live in homes where both parents smoke.People are becoming very aware of the dangers of second-hand smoke. 5 A. Recently, though, scientists changed their opinion after they studied a large group of nonsmokers.B. The Gilsons have been married for 35 years.C. This smoke is called second-hand smoke.D. However, second-hand smoke is dangerous to all people, old or young.E. As a result, they have passed laws which prohibit people from smoking in many public places.F. In the United States, nine million children under the age of five live in homes with at least one smoker.
