Medical Journals

　　Medical 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 publish only online. A few medical journals, like the 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 case reports may be published in medical journals to educate physicians about particular illnesses and how to treat at 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 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.

Ford Abandons Electric Vehicles

　　The Ford motor company’s abandonment of electric cars effectively signals the end of the road for the technology, analysts say.

　　General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now announced it will do the same.

　　Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about l,000 of the cars have been produced, and less than 1,700 carts have been sold so far in 2002.

　　“The bottom line is we don’t believe that this is the future of environment transport for the mass market.”Tim Holmes of Ford Europe said on Friday,“We feel we have given electric our best shot.”

　　The Think City has a range of only about 53 miles and up to a six-hour battery recharge time. General Motors’EVI electric vehicle also had a limited range of about 100 miles.

　　The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles.

　　“There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on,”Roger Higman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.

　　Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines Offer Greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines“on vehicle emissions” in the US.

　　However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.

　　1. What have the Ford motor company General Motor’s and Honda done concerning electric cars?

　　A） They have started to produce electric cars.

　　B） They have done extensive research on electric cars.

　　C） They have given up producing electric cars.

　　D） They have produced thousands of electric cars.

　　2. According to Tim Holmes of Ford Europe，battery-powered cars _____ .

　　A）will be the main transportation vehicles in the future

　　B）will not be the main transportation vehicles in the future

　　C）will be good to the environment in the future

　　D）will replace petrol-powered vehicles in the future

　　3. Which auto manufacturers are still producing electric vehicles?

　　A）Toyota and Nissan

　　B）General Motor’s and Honda

　　C）Ford and Toyota

　　D）Honda and Toyota

　　4. According to the eighth paragraph, hybrid cars

　　A）offer fewer mileage than petrol driven cars.

　　B）run faster than petrol driven cars.

　　C）run more miles than petrol driven cars.

　　D）offer more batteries than petrol driven cars.

　　5. Which of the following is true about the hope of car manufacturers according to the last paragraph?

　　A）Low-emission cars should be banned.

　　B）Only zero-emission cars are allowed to run on motorways.

　　C）The legislation will encourage car makers to produce more electric cars.

　　D）The legislation will allow more low-emission to be produced.

New U．S．Plan for Disease Prevention

　　Urging Americans to take responsibility for their health, Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage communities to do more to prevent chronic diseases like heart disease, cancer and diabetes.

　　The initiative highlights the cost of chronic diseases 一 the leading causes of death in the United States — and outlines ways that people can prevent them, including better diet and increased exercise.

　　“In the United States today, 7 of 10 deaths and the vast majority of serious illness, disability and health care costs are caused by chronic diseases,”the Health and Human Services Department said in a statement．

　　The causes are often behaviora — smoking, poor eating habits and a lack of exercise.

　　“I am convinced that preventing disease by promoting better health is a smart policy choice for our future,”Thompson told a conference held to launch the initiatiative.

　　“Our current health care system is not structured to deal with the escalating costs of treating diseases that are largely preventable through changes in our lifestyle choices.”

　　Thompson said heart disease and strokes will cost the country more than $351 billion in 2003.

　　“These leading causes of death for men and women are largely preventable, yet we as a nation are not taking the steps necessary for US to lead healthier, longer lives，”he said．

　　The $15 million is slated to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more.

　　Daily exercise such as walking can prevent and even reverse heart disease and diabetes, and prevent cancer and strokes.

　　The money will also go to community organizations, clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening.

　　The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests for cervical cancer, mammograms for breast cancer, colonoscopies, and prostate checks．

　　if such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.
