29. Some people believe that the Earth is being harmed (damaged) by human activity. Others feel that human activity makes the Earth a better place to live. What is your opinion? Use specific reasons and examples to support your answer.
When it comes the issue whether human activity can harm the earth or not, different people hold different views. If I were faced with the same question, I would probably say that it could harm the earth, especially to the environment. In the following discussion, I would like to reason and provide evidence to support my opinion.
The most important reason I cannot neglect is pollution. As we all know, one of human activities is that human cut trees, then they build houses and factories. These activities pollute the air seriously. Beijing, the capital of China, has undergone several sandstorms these years. Why? Because people cut trees that were planted in the suburb of Beijing in order to cultivate the crops. Nowadays, more and more people drink bottle water not the water flowing from faucets. Why? Because our rivers were polluted with the chemical material discharged by factories. We need use suntan oil to protect our skins when we are out. Why? Because the ozonosphere was destroyed by human activity. If you can understand this, you can understand my view better.
Another head and chief important reason I have chosen to put here is that human activity causes greenhouse effect. Don’t you realise that the weather is more and more warm these years? Why? Because people construct a lot of mansions and roads these years. They use glass as wall to built high rises, they use concrete to pave roads. All these construction materials cannot absorb but reflect the sunlight to the air. And most people like to use air conditions in summer, this action also make the air warm. If the weather was continuously warm, it could melt the iceberg and glacier that would bring a terrible disaster to the world. Don’t you think this example is persuasive?
Last but not the least reason is that human activity could make animals and plants extinct. There are many animals we can only see from the zoo not from the nature. Why? Because human activity destroy their living places and they cannot find enough food in the forest. The only safe place to them is the zoo. Don’t you think it is awful?
To sum up, given all the reasons discussed above. We can safely reach the conclusion that the earth is being harmed by human activity. The only thing we can do is to protect the nature lands instead of to develop them.
5. A company has announced that it wishes to build a large factory near your community. Discuss the advantages and disadvantages of this new influence on your community. Do you support or oppose the factory? Explain your position.
When it comes the issue whether building a large factory near the community is good or not, different people hold different view. When I were faced the same question, I would probably disagree to build a large factory near my community. In the following discussion, I would like to reason and provide evidence to support my opinion.
The most important reason I cannot neglect is environment pollution. A large factory would bring polluted smoke, polluted water and polluted residue to my community. Nowadays, more and more people drink bottled water not the water flowing from faucets. Why? Because our rivers were polluted with chemical material discharged by factories. We sweep the floor and wipe the table every day, but they become dirty just after a short time. Why? Because the factory emits the black smoke which makes the air full of dust through chimney. Can you bear the same thing happening on your home? If you could understand this, you could understand my view better.
Another head and chief important reason I have chosen to put here is noise. As we all know, the product lines of the factory run 24 hours every day. That means you must bear the noise from the factory all day and all night. If you were a person easy to wake up by noise, you couldn’t get a good sleep every night. That must influence your study and work in the following day. And I get knowledge from a magazine, permanent noise is also a killer to human. Noise is harmful to our health that can cause us nerve, worry and depression. Do you want to live in a quite place or a noisy place? The answer is obvious so that you must agree my opinion.
Last but not the least reason is traffic problem. Just think about it, a large factory must hire many people to work in it. That means there will be a lot of vehicles parking in your community even occupy your parking lots.
Admittedly, building a factory has some advantages, such as solves the problem of employment, brings the tax to the community. But the disadvantages carry more weight than the advantages. So we can safely reach the conclusion that building a factory in the community is not a wise choice.
113. The government has announced that it plans to build a new university. Some people think that your community would be a good place to locate the university. Compare the advantages and disadvantages of establishing a new university in your community. Use specific details in your discussion.
When it comes the issue whether establishing a new university in your community is a good thing or not, different people hold different view. If I were faced the same question, I would probably agree this suggestion. In the following discussion, I would like to reason and provide evidence to support my opinion.
The most important reason I cannot neglect is that establishing a new university can bring many career chances to the people in our community. Just think about it, when you built a new university, you must hire a lot of construction workers, such as brick layers, plumbers, carpenters, gardeners and so on. After you built the university, you must hire a lot of university clerks to manage this university, such as secretaries, administration clerks and so on. Also you must hire professors to teach students. One university can solve thousands of people’s careers. It is good not only to our community but also to the society. If you can understand this, you can understand my view better.
Another head and chief important reason I have chosen to put here is that a university building in community can bring convenience to inhabitants. We can exercise in the university gym. We can surf the web in the university computer lab. We can study in the university library. Everything is free or only costs you a little money. Also you can hire a university student as a tutor to help your children’s homework. For example, I lived near a university when I was young. I liked to go to the university with my friends at the weekend, because the campus was so large that we could play soccer or basketball in the playground. Don’t you think this example is persuasive?
Last but not the least reason is that a new university can bring profit to community. Students are consumers, they spend much money on their life and study. Just think about, you can open a bookstore or a restaurant near the university that can bring you considerable earning. Also you can rent your rooms to students that can increase you income.
To sum up, given all the reasons discussed above. We can safely reach the conclusion that establishing a new university in our community is a good thing to us.
167. Your school has enough money to purchase either computers for students or books for the library. Which should your school choose to buy -- computers or books? Use specific reasons and examples to support your recommendation.
With the introduction of computers to the modern world, book, the traditional medium, are more and more challenged. Libraries often face the dilemma of whether to invest on computers or on books. With all aspects carefully considered. I think to invest on computers would be a better choice.
When equipped with computers, a library may run more efficiently than ever. Students or faculties may get useful information as fast as the computer can. A student may find it easier to type in only a key word and get the desired results, which, if done with books, may well need a long time scanning among many related books; A researcher may feel it more convenient to find an article on those CD series than in a paper book. With the development of computer technology, such as the increase of CPU rate, memory, or embedding of cache on the main-board, the efficiency of data retrieval can only be accelerated, whereas a man’s reading speed is normally limited to some extent.
The efficiency of getting information is the readers’ major concern. While for the librarians, what they care most is how to store as much as possible information within limited space.
A computer has a large storage capacity. When a book with 750,000 Chinese characters is stored as electronic text, it only takes about 1M bytes on the hard disk. When stored on a normal CD with 640M capacity, when these CDs are packed in locks, much precious space will be spared for other uses.
Unlike a book, a mortal physical medium, a computer may keep all data on its disk safe and sound. It is very easy for us to copy, backup, or transfer those data to record able CDs or other recording materials.
The last but not the least, Internet may provide these computers with more capabilities of future information exchanges.
Books, certainly, have their own merits. People have enough reasons to cherish this traditional medium. Books are easy to carry, more affordable and conveniently read without extra consumption of any other type of energy. However, for a modern library, computers, equipped with much more important merits like high efficiency large capacity, durability and Internet accessibility, can be more reasonably treated as a wiser choice.
