Very hot weather is common in many parts of the world. Although hot weather just makes most people hot, it can cause medical problems and death.

Floods, storms and other terrible natural events kill thousands of people every year. And we hear much about them in news reports. We general hear little about heat（热）, which experts say may be nature’s most dangerous killer.

Health experts say that since the year 1900, very hot weather has killed more people in the United States than any other natural event. One year—the unusual hot summer of 1980 heat caused about 1,700 deaths in the United States. In 1955, more than 600 people died in another heat wave in one city—Chicago, Illinois.

Besides drinking lots of cool water, doctors say there are some other things to do to protect against the health dangers of heat. Stay out of the sun, if possible. Wear loose and light-colored clothes. Wear a hat while in the sun. Eat fewer hot and heavy foods. And, cook foods during cooler time of the day. If possible, rest more often.

Health experts say these simple steps can prevent the dangerous health problems caused by heat. They will prevent sickness, help you feel better and may even save your life.

Rich or poor, young or old, we all have problems. And unless we deal with our problems, we can easily become unhappy. Worrying about our problems can affect how we do at school. It can also influence the way we behave with our families. So how do we deal with our problems? There are many ways.

By learning to forget.

Most of us have probably been angry with our friends, parents or teachers. Perhaps they said something you didn't like, or you felt they were about a small problem. Time goes by, and good friendships may be lost.

When we are angry, however, we are usually the ones affected. Perhaps we have seen young children playing together. Sometimes they have disagreements and decide not to talk to each other. However, this usually does not last for long. This is an important lesson for us: we can solve a problem by learning to forget.

By regarding problems as challenges.

Many students often complain about school. They might feel they have too much work to do sometimes, or think the rules are too strict. We must learn how to change these “problems” into “challenges”. Education is an important part of our development. As young adults, it is our duty to try our best to deal with each challenge in our education with the help of our teachers.

By thinking of something worse.

By comparing yourself to other people, you will find your problems are not so terrible. Think about Stephen Hawking, for example, a very clever scientist, who regards his many physical problems as unimportant. He can't walk or even speak, but he has become very famous and successful. We are probably quite healthy and smart. Let's not worry about our problems. Let's face the challenges instead.
