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. Paragraph 4

Future Kitchen In a house, the kitchen is most likely to change in the future. The refrigerator may be able to talk to the owner when some part of it wears out. So before it stops working, the refrigerator itself" may let you know that there’s a problem. In addition, your fridge will also be able to tell you what are inside it. You don’t need to stand in front of an open refrigerator and look for what you want. When you have taken out the food from your refrigerator, your table may suggest recipes based on what you put on it. How is this possible The reason is the tiny computer chips, called RFIDs. They will be put in all the equipment in your kitchen, and even in furniture. Besides refrigerator and table, other equipment in your kitchen will benefit you because of the chips. The washing machine will know how to wash plates cleaner. And you will be able to control your oven with your cell phone. You put your dinner into the oven before you leave home, and your phone will tell the oven when to start cooking, so that the meal has been ready when you get home. When you go to a grocery store, the RFIDs will also help you a lot. You put the chips in your shopping bag before leaving home, and then they wild tell you what you already have in your refrigerator. And the chips will charge your credit card, so that you don’t need to wait for a long lime before the cash desk any more. If you love all the things today’s kitchen can do for you, you’ll love what tomorrow’s kitchen will do for you. The writer’s attitude towards future kitchen is ______.
The Hammersmith Hospital in West London, home of the Royal Post-graduate Medical School has been the scene(发生地点) of many innovations in medicine. It is now home(中心地,根据地) to the most expensive and ambitious medical technology project ever in Britain, which this year will make the Hammersmith the world’s first fully digital hospital. The paper-free office brought about by computerization and modern information technology is familiar to(为……所熟悉) many office workers today. It has taken longer for the same technology to be applied to medical imaging(医学影像学), because of the immense computing power and high cost o the equipment required. But now the Hammersmith is becoming the first hospital in which all imaging data-- X-rays, ultrasonic ,CT and MRI images--are stored not on cumbersome, inflammable films but as digital data on optical discs. The first consequence of this can be seen in the air-conditioned computer room in the new building, where two compact(坚实的,结实的) cabinets each about as tall as a man and 0.6m wide are ready to store every X-ray and scan made at the Hammersmith in the next 16 years on optical discs(光盘). Space saving is the most obvious but not the most important advantage of the digital h6spital. A consultant conducting a clinic with a workstation linked by fibre optics(光纤) to the data store has no need of cumbersome trolleys loaded with patients’ X-rays. The new technology considerably reduces the exposure to ionizing (电离的) radiation needed to get pictures doctors need, corresponding to reducing the slight but inevitable health risk that come with repeated X-rays. X-rays record their images on fluorescent(荧光的) plates, lasers read off and store the data and the plates are wiped clean to use again. This requires less radiation than conventional(常规的) imaging. The ability to enhance imaging also reduces the need for extra exposures. Another advantage is that any stored image can be sent to any of the hospital’s 138 workstations in four seconds(soon that will come down(降落) to two seconds). Soon it will be possible to send it direct to other hospitals, or to computer screens in GP’s(全科医生) clinics. PACS(图像存档通讯系统) is the most expensive single medical technology project ever funded in UK. Most of the money has come from the Department of Health, which has realized that it will benefit patients at the Hammersmith Hospital and those referred from elsewhere, in terms of(按照) better, quicker and safer diagnosis and treatment. Another technique uses radio a belled(用放射性同位素示踪的) white blood cells to guide doctors to the sites of hidden abscesses(脓肿) or other trouble spots. In the most innovative technique of all, interventional(干预的,介入的) radiology, doctors use tiny instruments at the ends of fine catheters(导管), inserted deep into the body under local anaesthetic, to perform a growing amount of microsurgery, viewed by surgeons—and patients if appropriate—in extremely clear detail. Every scrap(碎片,段) of unwanted image is electronically edited off the screen by the computer. The Hammersmith Hospital is also pioneering interventional radiography, in which doctor carry out microsurgery at the same time as they image the patients’ organs in minute detail. The blocking or unblocking of arteries to prevent damage due to bleeding or thrombosis(血栓形成) is among the conditions now being treated in this way. A "digital hospital "means______.

Diet, Alcohol Linked to Nearly One Third of CancersDiet is second only to tobacco as a leading (1) of cancer and，along with alcohol，is responsible for nearly one third of cases of the disease (2) developed countries, a leading researcher said on Tuesday.Dr. Tim Key, of the University of Oxford, told a cancer conference that scientists are still discovering how certain foods contribute to (3) , but they know that diet, alcohol and obesity (4) a major role."Five percent of cancers could be avoided (5) nobody was obese," he said.While tobacco is linked to about 30 (6) of cancer cases, diet is involved in all estimated 25 percent and alcohol (7) about six percent.Obesity raises the (8) of breast, womb, bowel and kidney cancer, while alcohol is known to cause cancers of the mouth, throat and liver. Its dangerous impact is (9) when combined with smoking.Key told the meeting of the charity Cancer Research UK (10) other elements of diet linked to cancer are (11) unknown but scientists are hoping that the EPIC study, which is comparing the diets of 500, 000 people in 10 countries and their risk of cancer, will provide some (12) Early results of the study have revealed that Norway, Sweden and Denmark have the (13) consumption of fruit and vegetables among European countries while Italy and Spain have the highest. Eating at (14) five portions of fruit and vegetables a day is recommended to reduce the risk of cancer.Key, principal scientist on the EPIC study, said it is looking at dietary links to some of the most common cancers (15) colorectal, breast and prostate. 51（）
