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 should 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 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, scientists 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 research 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, 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. 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 is worthwhile for the purpose to accelerate the development of science and the progress of human civilization. (299 words)
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 most 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 everywhere 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 health. 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 exploration 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 technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent. (286 words totally)
With the rapid development of society, we have entered an era of information explosion. In order to acquire more knowledge, more and more people decide to further their study abroad. Studying abroad brings about many advantages. It widens students' knowledge and horizons, and meanwhile cultivates their independence and personalities.
Firstly, students can learn advanced knowledge and experience abroad. Since the reform and the policy of opening to the outside world, China has strengthened cooperation with many countries. As a result, the scientific and technological level has been improved very rapidly. However, compared with the developed countries in the world, we still have a very long way to go. Studying abroad provides opportunities to students, who can learn advanced knowledge and management experience, so as to enhance the scientific level in our country.
Secondly, studying abroad can cultivate students' ability to live independently and their characters. Students have to deal with many problems when they study abroad. They have to learn how to be accustomed to a new environment and how to get along with the teachers and classmates. During their study, they can acquire some interpersonal skills.
Finally, studying abroad can provide a good language environment to students and make it easy to pick up a language. Foreign language is a tool employed to communicate with each other. It can remove language barrier and make international cooperation much easier.
However, "Every coin has its two sides". Studying abroad also brings about many disadvantages. Firstly, students will be confronted with so many psychological problems. They often feel lonely and helpless in a new environment. Furthermore, the tuition is very high, which is a very heavy financial burden to the average people.
To sum up, the advantages of studying abroad outweigh the disadvantages greatly. We encourage students study abroad. When they accomplish their curriculum, they can make more contributions to the construction of our society. (313 words)
The improvement of peoples living standard owes too much to the rapid development of science and technology. However, people nowadays are confronted with so many problems, such as the deterioration of environment, air pollution and the explosive expansion of population. Some people claim that the damage to environment is an inevitable consequence of economic development. From my point of view, this is only an excuse for the ignorance of environmental protection. (71 words)
In order to make more profit, some manufacturers and factories are only keen on the pursuit of profits, caring nothing about the protection of environment and the recycling of waste water. For example, about fifty percent of people in Shenzhen possess a private car, and the ownership is increasing by 7,000 each month. The exhaust gas and irritating noise impair peoples health greatly. The prosperity of economy is obtained at the cost of peoples health and the damage to environment. (81 words)
The lack of awareness of environmental protection is another factor causing damage to environment. Some near-sighted local governments are only concerned about economic development but pay little attention to environmental protection, misunderstanding that economic development says for their achievements and that environmental protection only wastes money. (46 words)
If people and the authorities concerned have a long-term developing perspective, I think the damage to environment is avoidable. Along with the development of technology and peoples living standard, the government should take effective measures to handle the problems arising. Meanwhile, the manufacturers and factories should consider not only economic profit but also social benefit. If the government and people can join hands in solving environmental problem, we will enjoy an azure sky and flower fragrance in the near future. (80 words) (278 words totally)
