Different weather makes people feel different.It influences health, intelligence(智力) and feelings.

　　In August, it is very hot and wet in the southern part of the United States.People there have heart trouble and other kinds of health problems during this month.In the Northeast and the Middle West, it is very hot at some times and very cold at other times.People in these states(州) have more heart trouble after the weather changes in February or March.

　  The weather can also influence intelligence.For example, in a 1983 report by scientists, IQ(智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower.The wind can help people have more intelligence.Very hot weather, on the other hand, can make it lower.Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).

　　Weather also has a strong influence on people’s feelings.Winter may be a bad time for thin people.They usually feel cold during these months.They might feel unhappy during cold weather.But fat people may have a hard time in hot summer.At about 18℃, people become stronger.

　Low air pressure(气压) may make people forgetful(健忘).People leave more bags on buses and in shops on low-pressure days.People feel best at a temperature of about 18℃.

Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather’s problem.

　　I wonder if there is any girl or boy who does not like to see a rainbow (彩虹) in the sky. It is so beautiful.

　　There is a story, saying that whenever you see a rainbow you should run at once to the place where it touches the ground, and there you would find a pot of gold. Of course it is not true. Neither you could find the pot of gold, nor could you ever find its end. No matter how far you run, it always seems far away.

　　A rainbow is not a thing that we can feel with our hands as we can feel a flower. It is only the effect (结果) for light shining on raindrops. The raindrops catch the sunlight and break it up into all the wonderful colours which we see.

　　It is called a rainbow perhaps because it is made up of raindrops and looks like a bow (弓).

　　That is why we can never see a rainbow in a clear sky. We see rainbows only when there is rain in the air and the sun is shining brightly through the clouds. Every rainbow has many colours in the same order. The first or the top colour is always red, next comes orange, then green, and last of all blue. A rainbow is indeed one of the wonders of nature.

Two magazines recently listed the best cities to live in. Here are two of the cities listed as "the world's best."

　　SAN JOSE, COSTA RICA The city has comfortable weather all year round (15℃ to 26℃). Housing is not very expensive in San Jose. Also, many of the city's older neighborhoods are very beautiful and have small hotels and cafés. Beautiful mountains are around the city. Lots of people go sightseeing there every year. But air pollution is a problem in the city center.

　　HONG KONG, CHINA This lively city-once a small fishing village-is today an international business center. It is an interesting mix of East and West, old and new. Modern tall buildings are next to small temples (庙宇). Popular nightclubs are close to traditional teahouses. Busy people fill the streets at all hours of the day. But outside the city, there are parks for walking or relaxing. Hong Kong is famous for its wonderful native dishes. There's also food from Europe, North America, and other parts of Asia. However, this small city has a large population of nearly seven million! That's why housing is very expensive. Traffic and air pollution are also a problem.
