However, this is not true for education. At a simple level some subjects may be better taught using computers, but to explain important concepts a human teacher is still indispensable.Why computers do well, with examplesThere are some subjects in which a computer can be used successfully to teach. Elementary mathematics,elementary language leaning, any area which requires a student to memorize basic facts through repetition is well suited to computer learning. The computer can be programmed to provide an endless number of simple questions, and as the student answers these questions the facts are learned and reinforced.What computers cannot be, with an exampleHowever, in the learning and practice of more complex ideas, the computer is not adequate. A computer can evaluate an answer as right or wrong, but it cannot determine why. It cannot find out why a student is making mistakes, and then re-present important concepts in a different way so the student will understand. It cannot determine at what stage in a mathematicsproblem the student has made an error, it can only indicate that the final answer is wrong. Tasks involving reasoning cannot be taught by computers, as there are too many variables for a computer to deal with successfully.Conclusion re-states main ideasThus, while computers maybe useful as a tool for practicing simple skills, they are not an essential feature of modern education, because they cannot monitor a student’s grasp of concepts, nor evaluate a student’s reasoning. Until further developments in computers are made the human teacher will remain indispensable.E-books versus traditional booksThere is no denying the fact that e-books have been gaining increasing popularity in the past years with the development of information technology. Nowadays, more and more people read e-books instead of the traditional way. E-books versus traditional book, which are the winner?Some people claim that E-books are convenient to read on line as modern people have easy access to the Internet while having less and less time to frequent the bookstore. Besides, reading e-books saves money. Nonetheless, E-books are not goodfor intensive reading and comments.How are traditional books? Traditional books are good for collection especially what are valuable. And the paper books is one way of people communication. However, it is not convenient to save, search.To conclude, E-books and traditional books all have their own shortcomings and advantages. Although E-books are a very valuable tool that could be used as a profit center. Reading paper books can give people a sense of satisfaction since that they can know what they read clearly. Therefore, E-books will not win traditional books.The importance of physical exercisesIt is well known that life lies in movement. Life for us is precious, but fragile. Life lies in physical exercises, physical exercises can bring vitality. Nevertheless, in modern society, with the improvement of living standards, the modern people pay less attention to the physical exercises and spend less time in physical exercises. It is reported that the health of young people in China, college students in particular, is not as good as is supposed to be. They are so busy, they are busy playing computer games, busy with their school work, but not busy at physical exercises. Even someone suppose thattaking exercises is a total waste of time. It is so terrible.There are many reasons for this fact, but the mian reason is that they don't realize the importance of physical exercises. So we should tell them the benefits of sports. First, doing sports properly can promote the level of intelligence. Second, it is good for the physical and mental health. Third, it is effective in regulate mood.In a word, physical exercises are crucial, so we should spend our time in physical exercises which make ours life more healthier, more happy, more beautiful.Nactive effects of televisionThe effects of television watching.With the development of science and technology, the application of hi-tech products is influencing people's life more profoundly. The popularization of media, in particular, is closely related to daily life. It covers newspaper, radio, television and mails and so on. And we all have a personal experience owing to our direct and frequent contact with television, so we know well the positive and negative effects of television watching.On one hand, if we watch television properly and with a clear purpose, we can learn something useful, especially when we watch some programs that is beneficial to our brain.Therefore, we advocate that more advantageous television programs should be held. Programs that are spreading incorrect and misleading concepts should be banned. As a transmitter of culture and knowledge, the contents of television programs should be and must be healthy so as to create a harmonious environment for our life as well as for children' development.On the other hand, watching television excessively could result in serious fritter of time. Although watching television is a good way to kill time and ease mind, we should not rely too much on it. We could have done a lot of significant things if the time wasted on watching television could be utilized to do something down-to-earth. We might have learned a skill, such as guitar, piano, and painting and so on. Besides, some television programs are really too meaningless, watching it is a total waste of time.Besides, some series and movies played on the television contains erotic and violent scenes that are detrimental to children' growth. The governing sector should make every effort to get rid of such undesirable things which can cause psychological deformity among children and grown-ups as well. Therefore, children are usually accompanied by their parents when watching television.What is more, watching television is harmful to our health, especially to children' eyes and ears.Near-sight is a very common phenomenon around the world, for nearly all the children have an easy access to television or other kinds of equipments. According to a health report, one to two hours a day is appropriate for children, or they have to relax for a while every half an hour.In my opinion, watching television is no doubt a useful tool to kill time and get information about the outer world as long as we set a proper limit on the time we spent on it. And no harm could be done to us if we maintain a correct posture towards it.Development and environmentEnvironment and Development, Which is more important? Nowadays ,the problem of the environment has become one of the biggest concern as our living conditions are getting worse and worse .The most important reason is that people develop economy at the price of the environment ,we have to think about, environment and development, which is more important?Some people think that the urgent task is to develop economy on a large scale. They hold the opinion that ,many people, especially in rural areas, are living in poverty. As a result,many children drop out of school and a large amount of peoplecan't afford medical treatment. they believe that only byfurther developing our economy can we live happer, It's timefor us to protect the environment until we reach this goal.On the other hand, many people insist that environment protection should be a top priority. First, they claim that wehave only one mother earth, if our ecological environment isheavily polluted or ruined, we could not even survive on thisplanet. Second, they believe, as most parts of the world arebadly polluted.we should do our best to improve our environmentuntil its to late.As far as I am concerned, the environment is much more important.money is not the only source of happiness, whenpeople live in harmony with the nature ,they can get spiritual fulfilment.In my opinion ,earth is our only home,we have a lot to doto protect it. Firstly, we should let people fully realize the importance of environmental protection through education. Secondly, much more efforts should be made to put the environment protection policy into practice. Finally, thosewho destroy the environment intentionally should be severely punished.Fortunately, more and more people have realized these matters. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.。
