范文一

Human life can not continue without science and technology. For many years, human society has developed with the advance of science and technology while the development of science and technology has in turn brought the process to mankind.

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 space rocket has opened a new era for mankind. Through the use of TV people can hear the sound and learn the events happening thousands of miles away. Owing to the invention of spaceship and rocket, the dream of man s landing on the moon has now come true.

Science and technology also play an important role in our socialist construction. We may say, our socialist construction is just like a skyscraper, while science and technology are its base. Without the base, the skyscraper can t be built.

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.

Notes:

in turn: 转而;反过来

bring about: 导致;引起

owe to:把 归功于

come true: 实现

socialist construction ：社会主义建设

contribute to: 为 作贡献

范文二

How does light get from the sun to the earth? How does music get from the stage to the audience? They move the same way in waves!

Light and sound are forms of energy. All waves carry energy, but they may carry it differently. Light and sound travel through different kinds of matter. For example, light waves cannot move through walls, but sound waves can. That is why you can hear people talking in another room even though you cannot see them. The energy of some waves is destructive. An earthquake produces seismic waves.

Catch a wave. Ask a friend to stand a few feet away from you. Stretch a spring between you. Shake the spring to transfer energy to it. What happens? The spring bounces up and down in waves. When the waves reach your friend, they bounce back to you!

Light waves travel 300,000 kilometers (186,000 miles) per second! They can also travel through a vacuum. That is why light from the sun and distant stars can travel through space to the earth.

范文三

As is shown in the graph, China s food distribution has taken great changes from 1960 s to 1990 s According to this statistics of cereals, vegetable, meat, and fruits, the number of those who eat rice, flour or vegetable has greatly decreased in the past four decades. In contrast of this the number of those who eat oil or meat has sharply increased. From such dietary changes, we can perceive the rapid improvement of our people s living standard.

Why does this improvement occur? The direct reason is the fa(中国有多少个县？截至2020年9月1日中国一共有1347个县，另有117个自治县，县作为“县级行政区”，属于三级地方行政区。)ct that the Chinese people have attached much importance to their health care. Nationally, China s economic growth is booming, and more people are getting richer. Individually, everyone s consumption of food is increasingly varied. In particular, most of people are reluctant to eat much vegetable, but much meat and oil in their diets.

In my view, the changes of China s dietary distribution seem to be both positive and negative. The positive aspect is that China s economical growth has given rise to the higher level of dietary standard, with most of people living rich and happy. But the negative aspect is that, I m afraid, less eating vegetable will lead to poorer health, such as lacking vitamin nutrients in one s body. Therefore, we think it necessary for the Chinese to be aware of the balanced diets: Lots of vegetable and meat, which may gain us healthier bodies in the new century.

范文四

We might marvel at the progress made in every field of study, but the methods of testing a person s knowledge and ability remain as primitive as ever they were. It really is extraordinary that after all these years, educationists have still failed to devise anything more efficient and reliable than examinations. For all the pious claim that examinations test what you know, it is common knowledge that they more often do the exact opposite.They may be a good means of testing memory, or the knack of working rapidly under extreme pressure, but they can tell nothing about a person s true ability and aptitude.

As anxiety-makers, examinations are second to none. That is because so much depends on them. They are the mark of success or failure in our society. Your whole future may be decided in one fateful day. It doesn t matter that you weren t feeling very well, or that your mother dies. Little things like that don t count: the exam goes on. No one can give of his best when he is in mortal terror, or after sleepless night, yet this is precisely what the examination system expects him to do. The moment a child begins school, he enters a world of vicious competition where success and failure are clearly defined and measured. Can we wonder at the increasing number of drop-outs : young people who are written off as utter failures before they have even embarked on a career? Can we be surprised at the suicide rate among students?A good education should, among other things, train you to think for yourself. The examination system does anything but that. What has to be learnt is rigidly laid down by a syllabus, so the student is encouraged to memories. Examinations do not motivate a student to read widely, but to restrict his reading; they do not enable him to seek more and more knowledge, but induce cramming. They lower the standards of teaching, for they deprive the teacher of all freedom. Teachers themselves are often judged by examination results and instead of teaching their subjects, they are reduced to training their students in exam techniques which they despise. The most successful candidates are not always the best educated; they are the best trained in the technique of working under duress.

The results on which so much depends are often nothing more than a subjective assessment by some anonymous examiner. Examiners are only human. They get tired and hungry; they make mistakes. Yet they have to mark stacks of hastily scrawled scripts in a limited amount of time. They work under the same sort of pressure as the candidates. And their word carries weight. After a judge s decision on you have the right of appeal, but not after an examiner s. There must surely be many simpler and more effective ways of assessing a person s true abilities. It is cynical to suggest that examinations are merely a profitable business for the institutions that run them? This is what it boils down to in the last analysis. The best comment on the system is this illiterate message recently scrawled on a wall: I were a teenage drop-out and now I are a teenage millionaire.
