the tape recorder
the tape recorder is one of the most welcome and popular electronic devices ever invented. there are many types of recorders. some may be as big as a hand box some may be as small as a watch. now a new type called walkman has come into being, which is so convenient that you can take it with you wherever you want to go. it is also very cheap, about forty or fifty yuan, and the most expensive one costs only several hundred, and it is very easy to handle even for a child. therefore, almost each family has one or two recorders.
this device is useful in many ways. it is not only widely used in our daily life, for example, filming, sporting, exercising, but also used in national security. it is an essential instrument for the young to learn foreign languages, for the old to listen to music or peking opera and for english teachers to make their class lively and interesting.
however, it can also become a nuisance if we use it improperly. it will have a bad effect on others or ourselves if we play it too long or too frequently. so we must make good use of it to promote our study and work.

computers
the computer is a wonderful machine. it is the most important invention in our modern time. today it is used a great deal in many ways. in the future the computer will probably touch the life of every one, even people in remote villages.
computers can do many kinds of work. for example, in big shops, information about the sale is put into a computer. during the night the computer works on the information from all the sales that day. the next morning, the manager has a report on everything that will soon be sold out. in scientific researches, a scientist can “ask” a computer some questions. this is almost like talking to another scientist.
in the past few years there have been great changes in computers. they now can do most of the things that people do, though most scientists have no idea about what computers of tomorrow will be like. will they make life better, or will they bring suffering to people? people today have to decide how to use the computers of tomorrow.

science and technology in modern life
human life cannot continue without science and technology. for many centuries, human society develops with the advance of science and technology. so the life we are living now is more civilized than that of our forefathers.
the development of science and technology has brought about many changes in people’s life. for example, the invention of television and the space rocket has opened a new era for mankind. through the use of tv people can hear and see the events, which happened or, are still happening thousands of miles away. owing to spaceship and the rocket, the dream of man’s landing on the moon has now come true.
science and technology also play an important role in our social construction. we may say that our social construction is like a skyscraper that cannot be built up without the help of science and technology. therefore, we should try our best to contribute to the development of science and technology so as to provide a more solid base to build our country.

what would happen if there were no power
ever since early this century, electricity has become an essential part of our modern life. it has played a decisive role in modern industry, agriculture, science and technology, national defense and education. nobody can deny that the development of our civilization depends on electricity.
if there were no electric power, our modern world would be in great trouble. for one thing, all the wheels would stop because the motors that power the machines would stop. for another, many of our industries would cease production. and all the electrical equipment such as washing machines, refrigerators, tvs would stop working. in short, our modern life would be impossible without electricity.
therefore, we should make better use of electric power. on the one hand, we should educate people to economically use electricity and not to waste the energy resources for the future. on the other hand, we must do our best to exploit more electric resources to meet the requirements of the human beings and to avoid energy crisis in the future.

my most favorite program
nowadays radios and tvs play a more and more important role in our daily life. there are many programs shown every day. some of them are very good. my most favorite program is called the animal world, which is provided by cctv every day night.
born and bred in the city, we can cot see any wild animals, and the program just compensates for it. it provides us with natural scenes and life of all kinds of wild animals with the explanation of the narrator. we also learn some knowledge about animals, even some plants. so, in my opinion, it is an interesting as well as instructive program. besides, the pictures are very beautiful and some of them are also very valuable. it’s really a great joy to watch it. if you don’t believe it, just watch it yourself.

newspapers
newspapers bring us news about current affairs. they help us know what is happening in the world. stories and sports columns are highly entertaining. and advertisements provide us with various kinds of information.
newspapers have several advantages over radios and tv. we can read them wherever and whenever we have time; we can keep them for later reference; we may cut out articles and trace developments in certain subjects.
today newspapers are not as important as they used to be, but they still play a role as a form of mass media. everyday more newspapers than books are read. their influence should never be underestimated.
however, the role of the daily press should be to broaden and deepen the reader’s view. instead of moving restlessly and dealing with one event briefly then quickly switching to another, the press should become less restless and dwell on fewer events.
