雅思大作文范文：电脑与老师

Computer is widely used in education, andsome people think teachers are not playing animportant role in the classroom. To what extenddo you agree?

Computer, as the most powerful tool in theinformation age, is widely applied in people’s work,study and daily life. A growing number of peoplethink optimistically that computer will replaceteachers in the classroom and play the leading role instudy. As far as I am concerned, it will not take theplace of teachers now and for good.

One of the main reasons is that computer workspursuant to the prescribed programs. It cannot work creatively and solve the queries fromstudents. Suppose a new problem arises in study, computer will be at a loss and unable toexplain the questions put forward by students. Although there is good news about theinternational chess games between computer and human beings, computer will never winbecause it is only a product of human intelligence.

Another reason is that computer cannot express feelings and emotions in communication.Communication plays an important role not only in constructing personal relations, but also inunderstanding each other clearly. Study is not a mere process of acquiring knowledge. It is,more important, an indispensable sector for people to communicate with each other andbuild interpersonal relations. Without feeling, everybody would become a cold creature andmake the world unbearable.

Last but not least, computer cannot take the place of teachers to organize teachingactivities and keep good order in the classroom. A good organizer can activate the atmosphereof study, triggering students’ study interest. In addition, study can only proceed in thecircumstance of good order. Otherwise, the classroom will become meaningless.

In brief, computer plays a role in students’ study. But it will never take the place of teachersin the classroom, for computer is a tool after all, which has many disadvantages.

With the rapid development of modern science,computers have been playing a more important rolein our daily lives. It is such a worldwide trend thatthere is no exception for Chinese.

Many people regard the computer as the magicmachine. It can solve many problems quickly andefficiently, and best of all, it can translate all kindsof languages. By using the computer you can just put ail the original versions into it and thenyou will get the fast translation. So some parents raise doubts about the necessity for theirchildren to learn foreign languages so hard any more.

At first thought, it seems that the computers can really help us to do so. But if you look in-sue the matter deeply, you may find a different answer. First of all, machines can never replacemankind. Computers are created by man and are controlled by human brains. We can neverrely too much on machines; otherwise we will become the slave of them one day. On thecontrary, we need to enrich our knowledge as much as possible so that we can catch up withthe fast pace of the world. It is very necessary to learn more languages so as to upgrade ourabilities to follow the progress of the world.

And furthermore, it will do good to children if they learn more languages. Both their brainand their thinking modules can benefit from it. When they grow up, they can easily acceptvarious kinds of cultures and communicate with foreigners, which can favorably enhance themutual understanding and develop international brotherhood.

So, we can clearly see that, though computers can be good translators, people still need tolearn more languages with a view to improving their abilities and facilitating their futurecommunication with people from other cultures.

An argument occasionally these days is thatsome people often think machine translation can takeplace of the children's study of a foreign language.As far as I am concerned, I can't totally agree withthis opinion.

It first comes to the point that machinetranslation is not high efficiency. The humanlanguage is so complex that nowadays no such machine can translate one language to anothersufficiently and totally. The machine can only provide some words or pieces of half-bakedsentences. So we human beings, especially children, may not rely on this kind of machine, atleast recently.

On the other hand, if the real machine that the whole sentence can be translated completelyturn to reality, children should not be taught not study a foreign language. The reason is thelanguage (especially speaking) is made up of not only the grammar and words but also tonesand mood. And when children are studying a language, he is not discovering an unknown area,but wild his logic and ideation. Additionally, even if the machine will be out of work one dayoccasionally in future, he can talk with other foreigners freely.

Frankly, the loss of language sensitivity is much popular these days. Many people'sspeaking and grammar is terrible. Children often study wrong speaking from annoying TVprograms and untrained broadcasters. The invention of translation machine will make it worse.The problem whether to teach the boys and girls foreign languages or not needs to be treatedseriously.

In a word, in modern society the translation machine is stealing our sensitivity of thelanguage. People should do something to prevent the loss of language ability, especially in thechildhood.
