2课后作文答案

<<新视野大学英语>>课后作文练习参考Book 2Unit 1Time is a Precious ResourceAs a popular saying goes, "Time is money.” In fact, time is more precious than money. When money is spent, you can earn it back if you want to. However, when time is gone, it will never come back. As the pace of modern life continues to accelerate, the time at our disposal is quite limited.But there are a lot of things to be done in our lives. We should make full use of our time to fulfill what is useful to us. For instance, as students we should devote most of our time to our academic studies. In this way we can acquire new knowledge and skill necessary for our future carrier.In my opinion, wasting time means wasting our valuable life. But many of us don't realize this. They think time is inexhaustible. I'm not in favor of such of a view. Hence, my conclusion is that we should never put off what can be today until tomorrow.English is becoming more importantAs it's known to all, English is widely used in international affairs and is becoming more and more important. English has become an international language used in different countries and different ways.China has joined in WTO successfully and it has been committing itself to opening and modernization. It means more and more foreigners will come to China for traveling and businesses. There is no doubt that we will have more chances to encounter foreigners on the way. Besides, many Chinese people will have more opportunities to work in a foreign companies and countries. English can help them communicate with foreigners. In addition, English enables us to learn advanced technology in western countries.All in all English is playing a very important role in our life. It is necessary for us to learn English well. Thus we can make our country stronger and more beautiful.Unit 2Fight against Gun CrimesToday the crime rate in some cities of our country is rising. Many citizens often complain about the thefts, robberies and even gun crimes that have taken place in the areas they live in and appeal to the governments at all levels to take effective measures to reduce the crime rate.Faced with criminals, some people are so frightened that they shamelessly give up the fight and other people turn a blind eye to them. However, some people are brave enough, to risk theirlives to fight the criminals. Their fearless actions prevented the criminals from doing evils, saved the victims, and protected the public properties.To reduce the crime rate, we all the people should first receive a law education. Criminals must be severely punished. Meanwhile we should set up a foundation to reward those who fight criminals. It is also important to call on people to learn from those heroes and encourage more people to stand up to crime.Against Populating ExplosionThe large number of our population has become one of the most serious problems of our society. According to a recent survey of the National Bureau of Statistics, there are more than 1.3 billion people in our country which account for about 1/5 of all the people in the world. The same survey also predicts that our population will grow quickly in the years to come.Overpopulation has brought about a series of negative effects to our economic development and social security. In the first place, too many people impose a heavy burden on our environment. As a result, we suffer from a shortage of fresh water and natural resources. In the second place, as the supply of labor greatly exceeds the demand of the society, many people become employed. This is a source of social unrest. Last but not the least; we have to meet the needs of the people, which cause environment pollution to our lakes and land.Serious though the problem seems, we have to take some measuresto tackle it. On the one hand, the government should carry out more strictly the poli cy of family planning, thus reducing the total number of population. On the other hand, all the people should realize the harms of overpopulation. With the concertedefforts of all the parties concerned, we’re sure to solve the problem in the future.Unit 3Smoking helps Thinking?Walking on the street, you will find many people smoking regardless of the others around. They say that smoking helps them think more clearly, give them energy and make me feel better if they’re worried or stressed.On the other hand, it is almost known to all that smoking is bad for people's health. Scientific researches show that smoking can lead to heart disease, cancer and other problems. The World Health Organization says diseases linked to smoking kill at least two millionfive-hundred-thousand persons each year.Measures have been taken to help people keep away from the harm of smoking. Government should help people learn about the health hazards of smoking and become successful ex-smokers. The danger of smoking should be warned of everywhere. In many cities, smoking is forbidden in public places. And newspapers are asked not to publish advertisements for cigarettes. World "No Tobacco Day" is observed every year as the biggest campaign against smokingPollution is inevitableWhen you turn on TV, you will hear many pieces of news on pollution. Pollution exists everywhere in our daily life.There are many kinds of pollution, such as water (air) pollution, soil erosion, garbage (esp. plastic waste), acid rain and so on. All vehicles and industrial machines emit harmful gases. Some factories send off waste water into our clean rivers and make it unfit to drink. Some land cannot grow plants.To solve the above problems, much knowledge and research work is needed. Scientists as well as common people attach primary importance to environmental protection.Without environmental protection, human beings would not last long. If there were serious desert expansion andsoil erosion, we would have no land to farm and no food toeat. If there were polluted air, water, we would get (suffer from) diseases and bec ome weak. If there were endless hunting of animals, we would kill human beings ourselves in the end.It is a duty for each person on the earth to protect his environment. Living surro undings are so significant for us that everyone should pay attention; no littering an d no spitting everywhere, etc.Unit 4Brazil Government has to Change its Policy of Colonizing the Amazon.The occupation pattern which prevails in the Amazon continues to be centered on big-business projects, fiscal incentives, and speculative capital, as was the case in the 1970s. Colonization has never been developed in the regions at least not by the government. It is necessary for the Brazil government to change its policy of colonizing the Amazon. There are many reasons.First, colonization projects aim at a combination of three objectives: (i) occupying virgin territory, (ii) social promotion of rural workers, and (iii) increasing agricultural production. However, these objectives are not compatible with one another, as the Brazilian experience has shown. The attempt to achieve them simultaneously has been translated into frustration in terms of colonization results. Second, the official colonization projects are characterized by scarcity of capital while land and labor are abundant.One of the alternatives would be to transfer colonization to private initiative or to adopt a strategy that would mix public and private initiatives. Others point out that the scarcity of low-cost credits is one of the factors which have prevented this undertaking from succeeding, besides its location far from fertile lands.Mixed Marriage Encounters more ProblemsWith the development of the economy and society, people get more chances to communicate with foreigners. Thus there are mixed marriages or interfaith marriages.Mixed marriages include those marriages that reach across otherwise “restricted” race, religious, and community boundaries set up by society, churches, and culture.Compared with common marriages, mixed marriages encounter more problems. There exist many differences in many ways, for example living habits, customs, religions and ways of thinking. When the mask of romanticism and novelty is dropped, they will find themselves, through the development of a loving maturity, as husband and wife, and as the father and mother of children. With time, their identities will re-establish their original foundations, those handed down to them by their original social environments.Knowing they are different, the mixed couple will tend to think more deeply about their marriage than the non-mixed couple. In order to keep their relationship and love between them, each should set his feet into the other’s shoes. They’d better have regular formal discussions about the direction they are headed. If each one tends to compromise, everything will be easy.Unit FiveFailing to Take Proper Measures to Protect the EnvironmentToday more than ever we are concerned about the environment and wonder whether humanity is heading for some ecological catastrophe. Pessimism prevails. We are warned by many scientists and environmental organizations that environmental destruction on a global scale, including global warming, ozone depletion, the reduction of tropical forests, desertification and ocean pollution, is threatening the existence of human beings and other living things on the earth. And if we don’t turn away from our present patterns of production and consumption, the very survival of humanity will be endangered.Many people agree with such views. However, some scientists hold the view of environmental optimism. They argue that many environmental problems are being exaggerated and that although problems do exist, advances in technology will be able to address them before serious consequences arise. They believe that there are no shortages of energy resources, that fewer people are starving today; that species are not disappearing at alarming rate, that growth is the solution to environmental problems like pollution and global warming.The debate, no doubt, will continue and everyone has to rely on their own wisdom to decide where they stand. But considering the seriousness of the issue, it is perhaps better that we err on the side of caution. We have only one earth, and it is our obligation to preserve it both for the sake of ourselves and for the sake of future generations.Difficulties Living in a New CountryWith the deepening of reform and opening-up of our country, many people dream of going abroad. They insist that the modern research facilities, world famous professors and excellent environment in those foreign colleges and universities can help lay a perfect foundation for their future development.It is true that living in a new country will bring them exciting and desirable fun. However, There are also some challenges they will encounter in a new country. Many people argue that living in a new country is too expensive. They also point out that there are language and cultural barriers. Their views may clash with the different beliefs and traditions existing in differentcountries. Furthermore, they cannot see their parents and friends for a long time. Sometimes they will feel lonely and homesick.Just as the old saying goes, “every advantage has its disadvantage.”Both opinions are acceptable in some sense. If you have the chance and financial resources, you should seize the opportunity to go abroad and broaden your eyes. On the other hand, if conditions do not permit, you can pursue your studies in top universities at home. What counts is not the place where they study, but what they can learn.Unit SixOnline LearningBeing online is no longer something strange in our life. To some degree, it has become part of our daily life. We can do a lot of things online, such as searching for information and communicating with friends far and near. But recently another helpful online activity has become very “in”. That is online learning.Why could online learning be so popular within such a short period of time? Among other reasons, the quick development of the Internet should be an essential one, which makes all our dreams of attending class in the distance possible. Another underlying reason is the quick development of both society and technology. Today, modern science and technology is developing with lightening speed. To catch up with this development we all feel an urgent and strong desire to study. However, due to the great pace of modern society, many people are too busy to study full time at school. Online learning just comes to their aid.Personally, I appreciate this new form of learning. It’s indeed a helpful complement to the traditional educational means. It can provide different learners with more flexible and versatile ways of learning. Most of all, with online learning, we can stick to our jobs and at the same time study and absorb the latest knowledge.Live and LearnTo live and learn is a good tradition as well as a merit of our nation. This tradition seemed to be revived in recent years. According to some statistics, more and more people are taking different kinds of training courses in their spare time. It goes without saying that the concept of “live and learn” will benefit not only individuals but society as well.We can easily find a lot of examples around us. It’s not difficult to find someone who is pursuing a second degree or diploma. More knowledge means more opportunities for better jobs and quicker promotion. In our age of information revolution, if we stop learning for a single day, we are surely to fall behind the wheel of social development. Therefore, only through never-ending learning can we recharge ourselves to get new skills for the future of ourselves and that of our country. For various reasons, some people lost the chance for learning or doing the things they are interested in. by taking certain courses they can fulfill their early dreams or their hearts’ desire.But we have to admit that there are some problems in adult education. For one thing, many people taking adult education only for the purpose of getting some certificates. I doubt whether they can really learn anything. For another, some people are quite blind in choosing courses. They don’t know what they really need or like. Instead, they just follow suit. In this case, scientificguidance and consultation become necessary.Unit SevenHis Good Name Brings Him Enormous SuccessNot everyone is fortunate enough to own a good name, but it is true that everyone wants to have one. That’s reasonable since statistics indicates that people with good names ha ve more opportunities of success.There are various reasons for this phenomenon. Firstly, a good name can help you make a great impression on others, because there is a trend to judge people by their names. As his name is, so is he! Secondly, a good name can give you more self-confidence. Social scientists say that what you are called can affect your life. What’s more, if you are satisfied with your name, you will feel comfortable with yourself and therefore put your potential into full play.So if you do not like your name given by your parents, if your name does not fit you, you can get rid of it by changing it. You are not stuck with the label. Movie stars regularly change their names, and with some determination, you can, too.What Lucky Numbers Have BroughtWith the development of science and technology, most people are scientific-minded. But there are still some people who believe in superstitions. They believe that lucky numbers can bring them good luck.In China, some people regard “6”, “8” and “9” as the lucky numbers. They try every means to use them as their door number, car number and even telephone number. Some young people prefer to hold their marriage ceremony on the date with an “8” or “9”. They think the number “6”stands for “to live peacefully and work satisfactorily”, and that the number “9” means “long and forever”. Some people take this numbers so heartily that they never mind paying a large sum of money for a telephone number with these figures in it.But, I don’t think that good luck has anything to do with “lucky numbers”. For example, in car accidents, many cars were cast with “lucky numbers”, but their owners still failed to escape from death. And those who held the lottery tickets with so many “8”s on them finally got nothing but a handful of waste paper. So we should abandon this kind of superstitious psychology and behavior. Just remember good luck only falls upon the sympathetic, generous and hardworking people.Unit EightIt is Never Too Late To Take Environmental MeasuresScientists and environmentalists have constantly warned us of the worsening state of our environment. Their view can be summarized in the list below: our resources are running out. The population is growing ever larger, ever more polluted. Large numbers of the planet’s species arethreatened with extinction. People often neglect environmental protection while developing economy. For instance, in order to make big profits, people often cut lots of trees. The deforestation destroys the ecological balance, and gives rise to disastrous consequences such as droughts and floods. To some extent, the faster the economy develops, the worse the environment becomes.There is a lose relationship between economic development and environmental protection. Without a good environment, it would be hard to develop our economy quickly since an unfavorable environment would hinder the further development of economy. On the other hand, with the rapid development and environmental protection are interdependent on each other.Then, faced with this situation, what should we do? From my point of view, first, we should make people aware of the importance of environmental protection. we should be more environmentally-conscious in our everyday activities . While we are developing our economy, we should attach great importance to our environment. Next, great efforts should be made to improve our environment. We should plant more trees, control the exploration of underground water and draw laws to protect our environment and to punish those who break them. Only in this way can we enjoy a clean and beautiful environment as well as a pleasant economic development.Never Let Yourself Be Overwhelmed by StressStress is a feeling of being unable to cope with the demands made on us. Its causes are varied. Long hours of work and study, hectic schedules, heavy responsibilities, quickened pace of life, job insecurity and misfortunes in the family are high on the list.Stress affects people in different ways and to different degrees, but most people suffer from its effects at one or more times during their lives. The most common symptom is insomnia, that is, the inability to sleep. As the pressure grows greater our health deteriorates, leading to an increased threat of heart disease, high blood pressure, etc.A great way to get rid of stress is, once in a while, break a habitual action and do something totally different without any planning. Other ways include saying‵no′to extra job requests, taking time off to be with family and friends, developing hobbies and helping others by doing volunteer work. Exercise is one of the most effective ways to relieve stress. Once people have learned to monitor stress, they can lead stress-free life.Unit NineMy Friend and I have Different Ways of Coping with StressIn recent years, we endure more and more stress. The pressure comes from both our leaders and our students. Our leaders expect that we make a lot of academic achievements, eg delivering excellent lectures, writing good articles; meanwhile our students can log on to the campus net and choose their favorite teachers.For the sake of our mental and physical well-being, it is necessary for us to relax ourselves. Going shopping is my favorite pastime. During the weekends I usually go to the supermarkets with my family members. There nobody urges me or presses me. Roaming among the shelves of goods I can take my time choosing our daily necessities, thus, for a while, completely getting rid of the heavy workloads.However, my friend has a different way to prevent herself from breaking down. In her free time, she likes to talk to me. She tells me of her troubles, worries and complaints. She usually pours her feelings out to me. Although I can offer nothing but comfort, after about an hour’seloquent talking, she usually feels relieved, consequently adapting herself to the quick pace of work.It is wise for us to think of ways to entertain and refresh ourselves. Otherwise we would have collapsed under such a heavy weight.Unit TenBrain Drain Becomes a Big Problem for the CountryDuring the 1960s and 1970s, politicians in India used to wave the slogan “stop brain drain” _____ a reference to the fact that the cream of India was leaving for the lucrative shores of England and America.Its institutes of technology, built with European and American aid, offered students free room and board, even salary. Indian taxpayers footed the bill in the hope that one day the graduates would help reconstruct the nation.But studying their textbooks late at night in the library of the Indian Institute of Technology the students would dream, not of India, but of America, the land of opportunity. Many students, indeed, left during those years, never to return.Over the next two decades, IIT graduates______ educated at the expense of Indian taxpayers_____ played a major role in founding California’s Silicon Valley.But the nation of India is slowly disintegrating. India’s population recently hit 1 billion, but its interior framework in water, transportation and health care is fast falling apart, its citizens breathe air that is dangerously polluted.German Bombers Hammered London with BombsIn Sept 1940, the Nazi bombers started to launch waves of heavy raids upon the city of London. On Sept 7, 1940, nearly four hundred German bombers roared into the ancient city, they cast dark and menacing shadows over the historic buildings of London. The invaders hammered the city with bombs in broad daylight. The bombers climbed, dived and turned, dropping thousands of bombs into the city, spitting fire in the skies above.Bombs crashed, fires burned, flames spread, houses collapsed, gas pipes burst, and dark smoke rose from the streets. Men, women and children felt the effect of the bombs. Radar sirens wailed, ambulances rushed from one place of agony to another and fire fighters faced the flames hour after hour.。
