your pocket and take it out when you want to watch a show. Imagine a guitar so tiny that you can"t see it
with the human eye, but you can hear sound when its strings are pulled.
Nanotechnology (纲米技术) is the science that deals with doing things in a very small way, and it is
being studied and developed all over the world. Many scientists say nanotechnology will produce the next
industrial revolution (工业革命) .
Perhaps nanotechnology will have the biggest influence on medical science. Imagine manobots (纲米机器人) in medicine. Thousands or even millions of tiny machines can be sent into the human body with
specific tasks. For example, they can be designed to find and destroy cancer cells or viruses (病毒). Other machines may stay in the human body for ever to help organs (器官) that are not working properly.
When could all of these happen? Scientists predict that most of these are possible in the next 30 years. Thousands of scientists around the world are working on these micro - machines. Nanotechnology is just around the corner.

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 that IQ of a group of students
was 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, 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 180C, people become stronger.
Low air pressure may make people forgetful. People leave more bags on buses and in shops in low pressure days.
There is "good weather" for work and health. People feel best at a temperature of about 180C.
Are you feeling sad, tired, forgetful or unhappy today? It may be the weather"s problem.

Traveling to the planets will be man"s next step. It will be more difficult than traveling to the moon and

In 1997, an American spaceship reached Mars, the second nearest planet from the earth. A wonderful robot slowly walked on the planet and worked hard. It sent a lot of information back to the earth. The
most exciting piece was that there used to be a lot of water on Mars. The American scientists asked, "Is
there any life on Mars?" Unluckily, no life was found there, but American scientists do not lose heart.
Russian spaceships have found that it is so hot on Venus that there must be no life there.
Spaceship of the future will be bigger and "faster. They will be able to carry people for travels to the
moon or other planets.
Man may in the future find planets l ike the earth and make them home. But there is still a long, long
way to go. Man should learn to know that the earth will be his only home for a long time and begin to love and take good care of it.
