1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-date雅思8分作文范文(课堂所需要)打印版雅思8分作文解决方案Intelligent machines such as robots are widely applied to take the place of human beings. Please discuss the advantages and disadvantages.The technology of i

2、ntelligent machines improves amazingly with the help of artificial intelligence. Robots, known as steel-collar workers, are widely employed in different aspects, such as marine research, space exploration and some modern assembly lines. Robots bring about advantages undoubtedly, and meanwhile, they

3、are not as versatile as expected. (49 words)The advantages of robots are innumerable. The employment of robots on assembly lines saves a lot of labor forces. Robots are widely used in developed countries. In Japan, one out of ten thousand workers are robots, which not only improve the working effici

4、ency, but also enhance accuracy. That is the reason why robots are so popular in automobile industry and electronic production line. (63 words)Another merit is that robots can take the place of human beings and work in the dangerous environment or the places not accessible for us. Human beings have

5、extended their cognition to the outer space, where there are considerable unpredictable dangers. Robots can work in any kind of situation, no matter how awful the environment is. In hospital, robots work as professional doctors doing operation on the patients. Furthermore, robots can work around the

6、 clock, never knowing what tiredness is. (80 words)However, the disadvantages of robots are undeniable. Firstly, all the robots and other intelligent machines are designed by human beings. What robots do is follow the instruction and pre-set programming by human beings. If there is something wrong w

7、ith the electric circuit or programs, robots will become good-for-nothing machines. Besides, robots cannot work creatively when confronted with complicated situation. (59 words)In short, robots are subsidiary to human beings. However competent they are in various kinds of field, robots will never ta

8、ke the place of human beings and play a decisive role in our work and life. (36 words) (287 words totally)Scientists use living animal to carry our research. Some people think it is interesting, while some other people think it is cruel. What do you think? Concerning the issue whether scientists sho

9、uld use living animals for scientific research, people hold different views. Some people claim that it is cruel, while some other people argue that it is beneficial to the development of science. As far as I am concerned, I am in favor of carrying out experiments on animals. Firstly, scientists can

10、do initial experiments on animals to test the effect of new medicine. Scientists have founded so many milestones on the way to medical development. But they can not find effective treatment to some diseases like cancer and AIDS, which are fatal to peoples health. Through experiments on animals, scie

11、ntists can not only understand the pathology of some diseases, but also try the effect of medicine and find the most effective treatment to these diseases, making great breakthroughs in the field of medicine. Secondly, using living animals in the laboratory, the teachers in the university or some re

12、search institutes can demonstrate the anatomic knowledge to the students majoring in medicine, rendering students a direct understanding of biological knowledge, which can improve the level of medical research and make great contributions to the medical science. Without experiments on living animals

13、, genetic technology would not have developed so quickly. Actually, most scientists attribute their success and breakthroughs to experiments on animals. Finally, some animals can provide human beings with essential organs for transplantation. Genetic technology will change the genes of some animals.

14、 In the near future, organs of animals will take the place of artificial organs like heart pumps, prolonging patients life. However, researches on living animals face a moral problem because animals are also creatures in the nature, which possess equal rights as human beings. On second thoughts, it

15、is worthwhile for the purpose to accelerate the development of science and the progress of human civilization. (299 words)The development of science and technology benefit our life. However, scientists cannot find effective solutions to the problems they created. To what degree do you agree or disag

16、ree with this opinion?The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which w

17、e must some solutions.Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the mo

18、st effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before. Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everyw

19、here they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel. Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples heal

20、th. Thanks to the endeavors scientists have made, these diseases become treatable.However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space explorat

21、ion has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce.Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and techn

22、ology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent. (286 words totally)What disadvantages will people meet if they cannot use computers? What should our government do?Computer plays a very important role in peoples work and life. We

23、 cannot imagine what our world would be like without computer. With the popularization of computer knowledge, computer is widely used in every aspect of peoples work and life. If a person cannot use computer, he will be confronted with a lot of trouble and difficulty.Firstly, most machines and equip

24、ment are controlled by computer nowadays, for example, automobile industry, manufacturing, power station and even airplanes. If a person cannot use computer, he will have difficulty in operating machines. It is hard to imagine that a pilot can fly an airplane without intimate knowledge of computer.

25、Without computer knowledge, people can not fit in with the rhythm of our society.Secondly, people can acquire rich information on computer through Internet. Internet, which abounds in innumerable valuable information, provides people with a lot of information about world events, arts, movies and the

26、 latest development of science and technology. If a person cannot use computer, he will be out of fashion and lag far behind the others. Finally, computer plays a very important role in education. For instance, students have to revise their thesis when they are fulfilling their thesis. Without a com

27、puter, the revision work will be tedious and frustrating. In addition, students can study long-distance courses on computer through Internet, which can enlarge their knowledge.Taking into account of the disadvantages motioned above, I think the government should do something to popularize computer k

28、nowledge. On the one hand, the government and the authorities concerned should popularize computer knowledge in primary schools and secondary schools, laying a solid foundation of computer knowledge for students. On the other hand, the society and the communities should organize some training courses for the people who cannot use computer. To sum up, the popularization of computer knowledge will not only benefit the people who cannot use computer but also the whole society. (318 words) -
