The Advantages and Disadvantages of Living in the 21st century(生活在21世纪的优缺点)Living in the 21st century offers certain advantages,such as a higher standard of living, but it also has some disadvantages, such as a polluted environment.To begin with, most people now have more money for less hard work. They earn higher salaries than before and enjoy better social security, such as social welfare for laid-off workers and disability insurance.Secondly, because of the advance in medical technology which leads to better medical care and treatment, people’s life expectancy is longer. Moreover, most people now can afford to buy foods of high nutrition and enjoy their leisure time.Thirdly, modern conveniences such as radio, TV, internet, various vehicles and labour-saving machines in the home, all greatly facilitate human communication, transportation and housework as well.Nevertheless, living in the 21st century also has its disadvantages. The most serious one is the increasingly polluted environment; air is filled with smog and water is contaminated by iehemicals from factories.Another main disadvantage is the personalization of human relattonships which mostly result from people’s ever-increasing contact with machines and numbers. Still one more disadvantageis the weakening of spiritual values. An undeniable fact is that a large number of people are solely interested in materialistic culture,while neglecting spiritual civilization. Limited by space, we have to skip the examples.In conclusion, although the 21st century has indeed given us a lot of advantages, it may not have made us wiser, because it has also made our earth dirtier, our people less humane, and our spirituali iife poorer, We shpuld continue to enjoy the benefits of technological advancement,however, we mustmake a concerted effort to preserve our natural environment for future generations. Moreover, we should take the time now to make our lives more meaningful in anihcreasingly impersonal, computerized world.二On responsibility .(关于个人责任)We Chinese place a high value on responsibility. It is traditional deal for us Chinese to take care of our parents. We owe them a great deal for the love they give us while we are growing up. It is right, then, when they are getting older with each passing day, we help them and see that they are well cared for. In this way, we give back some of the love and care they have given to us.As loyal Chinese citizens, we must have a strong sense of responsibility to our country. I t is our duty to keep China strong in the eyes of the world. Therefore, we shouldstudy and work hard for China’s strongness which also depends on the advanced science and technology. We must be willing to join the Army and defend our country, would we be threatened by an invader(侵入者). In short, to be a responsible citizen ,we must put our country’s welfare above our own needs. Finally, we must remember that we have a responsibility to the world we live in. It is important that we learn to live in peace with the other nations of the world and to protect our environment.If we carry out these responsibilities, we will be respected (受尊敬的)citizens of our country.三如何看待挑战For thousands of years, people have accepted challenges in different fields. There are not only physical challenges, but also social andintellectual(聪明的) challenges. Some people risk(冒…险) their lives in playing sports to see how well they can do. Others try to make and invent(发明) something to make life easier. They all enjoy challenges.Why do people enjoy these challenges? There are probably many reasons. One is curiosity. The other is the personal feeling of success, of achievement, and nowadays, for some people, it is a business.Today, we still have many challengers before us. Medical science faces the challenges of conquering manydiseases which still attack human beings. Engineers and planners must build new cities, design and produce new kinds of transportation. Scientists must develop new forms of energy. In short, we live in an age of challenges.四My View on Job-Hopping1. 有些人喜欢始终从事一种工作，因为……。

2. 有些人喜欢经常更换工作，因为……。

3. 我的看法。

Many people are inclined to do one job in their lives. In their opinions, people who change their jobs frequently are superficial and tactless. They believe that the only way to success is to stick to one job, for constant practice in a professional field helps make an txpert.But there are still many people who don’t agree. They argue that change means progress. If you are not satisfied with your present job, of course you have the right to replace it with a more challenging and better paid one. Every change is a step to further success. This idea may be. the reason why they change their jobs so often.For my part, I think it reasonable to change your job if you have a better opportuniry. But once you have found a position where you can fully display your ability, it is advisable to settle down to it and put all your efforts into it. Only in this way, can you get the true joy of achieving your goal.我对更换职业的看法许多人喜好终身从事一种工作。
