2017年科技类雅思作文范文篇
雅思考试每年都有很多场,考试的.内容会适度有所改变,但是热点却不会有太多的选择。下面就为大家送上三篇2017年科技类雅思作文范文,供大家参考。
2017年科技类雅思作文范文篇一These days, many people are afraid of nuclear technology because of the dangers associated with its use. In my opinion, although it is true that nuclear weapons pose the greatest threat to life, the use of nuclear technology for peaceful purposes also carries some serious risks.
Nuclear power stations provide an important source of cheap power for many industrialised nations and some developing countries. However, there is always the danger of radiation leaking from these plants. Even though safety precautions are taken, there have been numerous disasters such as the explosion of a nuclear plant in Russia not long ago.
Nuclear technology is even used to help cure some diseases such as cancer. Radiation can be applied to the body to burn away cancerous cells. This is, however, a dangerous procedure, and the application of radiation is almost always painful and not always successful.
The most worrying aspect of nuclear technology, though, is its use for military purposes. Enough atomic bombs have already been built to completely destroy the planet, and the real danger is that one day some country will start a war with these weapons. Too many countries now have the technology required to make such bombs, and there is currently much debate about how to control the situation.
In conclusion, nuclear technology certainly has positive uses, but is, nonetheless, dangerous. However, it would have been better if it had never been used to create nuclear weapons. If life on Earth is to continue.
2017年科技类雅思作文范文篇二There have been immense advances in technology in most aspects of people's lives, especially in the field of education. Nowadays, an increasing number of students rely on computers to research for information and to produce a perfect paper for school purposes. Others have decided to leave the original way of learning to get knowledge through online schools. These changes in the learning process have brought a special concern regarding the possible decrease of importance of teachers in the classroom.
Some people believe the role of teachers started to fade because computers have been helping some students to progress in their studies quicker than when compared with an original classroom. For example, in the same classroom, students have different intellectual capacities, thus some would be tied to a slow advance in their studies because of others’ incapacity of understanding. In this way, pupils could progress in their acquisition of knowledge at their own pace using computers instead of learning from teachers.
However, the presence of a teacher is essential for students because the human contact influences them in positive ways. Firstly, students realize that they are not dealing with a machine but with a human being who deserves attention and respect. They also learn the importance of studying in group and respect other students, which helps them to improve their social skills.
Moreover, teachers are required in the learning process because they acknowledge some student's deficiencies and help them to solve their problems by repeating the same explanation, giving extra exercises or even suggesting a private tutor. Hence, students can have a bigger chance not to fail in a subject.
In conclusion, the role for teachers in the learning process is still very important and it will continue to be in the future because no machine can replace the human interaction and its consequences.
2017年科技类雅思作文范文篇三For over fifty years, a number of nations have been involved in the exploration of outer space. This research has been very costly, of course. Has this money been well-spent or wasted?
Some people believe that all or most space research should be eliminated because of its incredible expense, not only in terms of money, but also in terms of scientific and human resources. These people point out the fact that it cost billions of dollars to send astronauts to the moon, but all they brought back were some worthless rocks. These people say that the money and effort now being wasted in outer space could be spent for homeless people, improving the education system, saving the environment, and finding cures for diseases.
However, other people believe that space research has provided many benefits to mankind. They point out that hundreds of useful products, from personal computers to heart pacemakers to freeze-dried foods, are the direct or indirect results of space research. They say that weather and communication satellites, which are also products of space programs, have benefited people all over the globe. In addition to these practical benefits, supporters of the space program point to the scientific knowledge that has been acquired about the sun, the moon, the planets and even our own earth as a result of space research.
I agree with those people who support space research and want it to continue. Space research, as shown, has already brought many benefits to humanity. Perhaps it will bring even more benefits in the future, ones that we can not even imagine now. Moreover, just as individual people need challenges to make their lives more interesting, I believe the human race itself needs a challenge, and I think that the peaceful exploration of outer space provides just such a challenge.
