电脑与现代教育

Introduction shows main idea

Computers are now essential in many areas of life – modern banking, retail and information exchange among others. 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 examples

There 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 example

However, 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 mathematics problem 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 ideas

Thus, while computers may be 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.

保持进步

Who would disagree with the statement "progress is good"? Without progress , there would be no change. Without progress, there would be no change in our economy, our standard of living, or our health.

Progress is required to keep the economy moving forward. New products need to be developed; new services need to be created. Without progress, our economy would stand still. There would be no change. Without progress, there would be no supermarkets with fress produce brought in from all over the world.

Progress is required to improve our standard of living. Our homes today are more efficient and use less natural resources thanks to improvement in home construction techniques. Our clothes are warmer and safer thanks to developments in textile manufacturing. Our educational system is better thanks to the use of the computers and the Internet.

Progress is required to improve the health of the world population. Without progress, there would be no vaccines against deadly diseases like smallpox. Without progress, there would be increased infant mortality. Thanks to progress, our lives are longer and healthier.

Progress is a natural state. Without it, we would not evolve. Without it, our economy, our standard of living, and our health would deteriorate. Who could deny the necessity of progress.

A principal's job is not as easy one. I only hope that in the future, I can model my own leadership abilities on the ones I observed in school. I hope I can be as firm, fair, and foresighted as my principal.

乘坐飞机的优缺点

In this section, you are to write an essay of about 200 words within 40 minutes. Your essay should be based on the information given below.

现在许多人愿意乘飞机旅行。随着我国民航事业的迅速发展，全国各大城市兴建了许多现代化的机场。乘飞机旅行有许多长处(方便、快捷、省时、舒适等); 但是，空中旅行也有许多不足之处(机票价格贵，有的旅客不适应空中旅行，常常感到身体不适，甚至有人还担心发生空难)。请你简单阐述上述两个方面。最后请你说明你的看法。

Many people prefer to travel by air. This is because air travel has some advantages. In the first place, airplane, the miracle created by man, is the fastest means of transport. It takes the least time for one to travel by air from one place to another. Secondly, traveling by air is convenient and comfortable. Friendly air hostesses are affectionate and considerate. They look after passengers all the way to their destinations. Moreover, on long distance flights there are films and music for people to entertain themselves.

As a popular saying goes, "Everything has two sides." The same is true of air travel. It has some disadvantages, too. For one thing, air travel costs a great deal. The average Chinese are not rich enough to afford expensive air fares. So they prefer to take trains, which save a lot of money. For another, although passengers are assured of their safety, they are still worried about it during the journey because flying always involves more or less risk.

As far as I am concerned, the advantages mentioned above exceed the disadvantages. If I were given choice between travelling by air and travelling by train, I would certainly prefer the former. For me, time is money and it is the most important thing I have to take into consideration whatever I do.
