illness called food poisoning. food poisoning is usually not serious, but some types are deadly. the symptoms of food poisoning usually begin within hours of eating the poisoned food. fever is one of the most common symptoms.certain microorganisms(微生物)cause most types of food poisoning. bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. after entering the body, these tiny living things release(释放)poisons that make people sick.some chemicals can also cause food poisoning. they are often added to food while it is being grown, processed, or prepared. for example, many farmers spray chemicals on crops to kill weeds and insects. some people may have a bad reaction to those chemicals when they eat the crops.some plants and animals contain natural poisons that are harmful to people. these include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.when people handle food properly, the risk of food poisoning is very small. microorganisms multiply rapidly in dirty places and in warm temperatures. this means that people should never touch food with dirty hands or put food on unwashed surfaces. food should be kept in a refrigerator to

not eat wild mushrooms or other foods that grow in the wild. some of these foods may contain natural materials that are poisonous to humans. in addition, some types of fish can be poisonous.most

know, teenagers are going through a special period of development both physically and psychologically. they are curious about and puzzled by the unexpected changes in their body and mind. whats more, exposed to a world of adults, it is only too natural for them to begin imitating adults behaviors in secret. boys begin to smoke and girls begin to spend time doing their hair and care more about what to wear. some even begin to date with a girlfriend or boyfriend without letting their parents know. they are doing this in secret because they are still unsure whether it is right to do so and afraid that, if found out by their parent, they will get misunderstood and even punished. in fact, in many cases, parents can not deal with such matters well but hurt their childrens feelings badly, making children unwilling to communicate with them any more. when this happens, it hurts terribly feelings of the family as well. therefore, it sounds reasonable and acceptable that teenagers should keep their secrets to themselves instead of sharing them with their parents, who should give them the freedom in dealing with secrets.写作内容1. 以约30个词概括上面文章的要点；2.
