Health Education1. Health education is the part of health care that is concerned with promoting healthy behavior. A person’s behavior may be the main cause of a health problem, but it can also be the main solution. This is true for the teenager who smokes, the mother with the poorly nourished (营养) child, and the butcher (屠夫，卖肉的人) who gets a cut on his finger. By changing their behavior these individuals can solve and prevent many of their own problems.2. Health education does not replace other health services, but it is needed to promote the proper use of these services. One example of this is immunization (免疫) :scientists have made many vaccines (疫苗) to prevent diseases, but this achievement is of no value unless people to go receive the immunization.3. Health education encourages behavior that promotes health, prevents illness, cures disease, and contributes to recovery. The needs and interests of individuals, families, groups, organizations, and communities are at the heart of health education programs. Thus there are many opportunities for practicing health education.4. Health education is not the same thing as health information. Correct information is certainly a basic part of health education, but health education must also address the other factors that affect health behavior such as availability (可获性) of resouces, effectiveness of community leadership, social support from family members, and levels of self-help skills. Health education therefore uses a variety of methods to help people understand their own situations and choose actions that will improve their health. Health education is incomplete unless it encourages involvement and choice by the people themselves.5. Also, in health education we do not blame people if they do not behave in a healthy way. Often unhealthy behavior is not the fault of the individual. In health education we must work with families, communities, and even regional and national authorities to make sure that resources and support are available to enable each individual to lead a healthy life.

What Makes a Soccer Player Great Soccer is played by millions of people all over the world, hut there have only been few players who were truly great. How did these players get that way-was it through training and practice, or are great players "born, not made" First, these players came from places that have had famous stars in the past-players that a young boy can look up to and try to imitate. In the history of soccer, only six. countries have ever won the World Cup-three from South America and three from western Europe. There has never been a great national team-or a really great player-from North America or from Asia. Second, these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player, as was Pele. Most players begin playing the game at the age of three or four. Finally, many great players come from the same kind of neighborhood-a poor, crowded area where a boy’s dream is not to be a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer. For example, Liverpool, which produced the Beetles, had one of the best English soccer teams in recent years. Pele practiced in the street with a "ball" made of rags. And George Best learned the tricks that made him famous by bouncing the ball off a wall in the slums of Belfast. All great players have a lot in common, hut that doesn’t explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others. The word "tricks" at the end of Paragraph 2 is closest in meaning to ______.
On British NewspapersBesides the daily newspapers, there are a number of Sunday newspapers in Britain. Many of them are connected with the "dailies", though not run by the same editor and his members. The Sunday papers are larger than the daily papers and usually contain more articles concerned with comment (评论) and general information rather than news. The national daily and Sun day papers have the largest circulation(发行) in the world. Of the Sunday papers, the Observer and the Sunday Times are the best known.It is a regrettable fact that the number of magazines of a literary or political nature has dropped down since the war. This has probably been caused by the ever-wider use of radio and television. The most successful magazines are those published for women. Their covers are designed to catch the eye, and they certainly succeed in doing so! They offer their readers articles on cookery (烹饪法), fashion, needlework, and many other matters of women interest. They also provide advice to those in love, and adventures with handsome heroes. Some women’s magazines also include serious articles of more general interest.The visitor who looks at the magazines displayed in a large bookstall (书摊) which may be found in an important railway station will notice that there is a wide variety of technical or semitechnical(半专业的) books and magazines. There are magazines for the motorist, the farmer, the gardener, the nurse, and many others.There are many local and regional newspapers. It is common in Britain for a news agent(报刊经售人) to deliver (投递) the morning papers to his customers for a small extra payment, this service is usually performed by boys and girls who want to earn some pocket-money. The Observer carries more political articles than The Sunday Times.()
