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.

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.
