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 every 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 students were very high when a very strong wind came, but after the strong wind, their IQ was 10%
below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面),
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 18C, 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. There are a  "good weather" for word and health. People feel best at a temperature
of about 18 centigrade (摄氏度).

     What do Napoleon, Clinton and Wang Nan have in common? They are all left-handed. 　　
     Today, about 15% of the number of people is left-handed. But why are people left-handed? The answer
is the way the brain (大脑) works. The brain has two halves-the right half controls the left side of the
body, and the left controls the right side of the body. So right-handed people have a strong left-brain and
left-handed people have a strong right brain. 　　
     The two halves of he brain are about the same size. But each side controls different things. The left side
controls language, math and logical (逻辑的). When you remember new words, or when you put things in
order, you use your left side. 　　
     The right side of the brain controls your love of art, colors and music. It is also good at recognizing (识别)
faces. 　　
     This does not mean that all artists are left-handed and all accountants (会计) are right-handed. Some
right-handers have a strong right brain, and some left-handers have a strong left-brain.

     Some people want to be sent into space after their death, others want to lie deep under the sea. But
most people want to go into the freezer (冷藏库). These are believers in cryogenics (低温冷冻学). 　　
     Now some diseases can't be cured, but they may be cured sometime in the future. So some people
hope that their bodies can be frozen after they die. When a cure is found，warm up his or her body, bring
it back to life and take the cure. Once the body is frozen, it is kept in liquid nitrogen (液态氮) at a
temperature of 328 degrees below zero. 　　
     Now around a thousand people are going to take cryogenic treatment (处理), though most scientists
say it won't work. If we freeze huge creatures (生物) like humans, every one of their cells (细胞) will be
broken. Can they be brought back to life in the future?

     Plants are very important living things. Life could not go on if there were no plants. This is because
plants can make food from air, water and sunlight. Animals and men can't make food from air, water and
sunlight. Animals get their food by eating plants and other animals. Therefore, animals and men need plants
in order to live. This is the reason why we find so many plants around us. 　　
      If you look carefully at the plants around you, you will find that there are many kinds of plants. Some
plants are large while others are small. Most plants are green.

are of different shapes and colors.

stalks, some have short leaf stalks, others even have no leaf stalks. The leaf edges are also different. Some
leaves have smooth (平滑) edges. Some have wave-shaped edges. Others have edges like the teeth of

     For several years, Americans have enjoyed teleshopping - watching TV and buying things by phone.
Now teleshopping is starting in Europe. In a number of European countries, people can turn on their TVs
and shop for clothes, jewelry, food, toys and many other things.
     Teleshopping is becoming popular in Sweden, for example. The biggest Swedish company sells
different kinds of things on TV in 15 European countries, and in one year it made＄100 million. In France
there are two teleshopping channels, and the French spend about＄20 million a year to buy things through
those channels.
       In Germany, until last year teleshopping was only possible on one channel for 1 hour every day. Then
the government allowed more telepshopping. Other channels can open for telebusiness, including the largest
American teleshopping company and a 24－hour teleshopping company. German businesses are hoping this
new teleshopping will help them sell more things.
      Some people like teleshopping because it allows them to do their shopping without leaving their homes.
With all the problems of traffic in the cities, this is an important reason. But at the same time, other
Europeans do not like this new way of shopping. They call teleshopping "junk on the air". Many Europeans
usually worry about the quality of the things for sale on TV. Good quality is important to them, and they
believe they cannot be sure about the quality of the things on TV.
     The need for high quality means that European teleshopping companies will have to be different from
the American companies. They will have to be more careful about the quality of the things they sell. They
will also have to work harder to sell things that the buyers cannot touch or see in person.

     Have you ever heard your own voice? "Of course," you say.
     Has anyone else ever heard your voice? Again you say, "Of course."
     But that's not quite true. Nobody else has ever heard your voice-the way you hear it. When you talk,
you set up sound waves (声波). The air outside your head carries the sound waves to your outer ears.
But, of course, the sound of your voice begins inside your head. The bones (骨头) of your head pick up
the sound waves, too. They carry the sound waves straight to your inner (里面的) ears. You get the sound
from the outside and the inside too. Other people get just the sound waves from the outside. That's why
they don't hear your voice the way you do.
