        Different weather makes people feel different. It influences (影响) 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 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. 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.

　　Every night the stars seem to move slowly round the sky in a great circle(圆周)．But one star is dif-ferent from others．It looks as if it never moved．To us, it is always in exactly the same place all thetime．It is called the Pole Star(北极星)．It is not a very bright star, but it is very important．Sailors use the Pole Star to find out where they are moving to．

　　The amazing(令人惊奇的)thing is that the stars are all so far away．If you travelled in the space-ship for a hundred years you would still not reach the nearest star!

　　A star is really a great ball of burning gas(燃烧的气体)，like the sun．Some stars are much bigger than the sun, But they are all so far away from us that they just look like dots(圆点)of light．

　　On the clearest night you can count about 2 000 stars．This may seem a lot, but with a telescope you can see many more．The better the telescope, the more stars you can see．Scientists tell us there are millions and millions of stars．No one know exactly how many there are．
