华农外教期末考试题目(附参考解答)

1.Do you think we should worry about the environment?I think we should not worry too much about the environment, but we are supposed to care about it. It just like our body, we care about our health, many people will run every evening, they go to the gym to become fit and strong, they eat vegetable and fruit for health, andthe problem of environment is big and complex, it contains many aspects, but it’s also small and simple, because it just like the body of every one of us, as long as we care about the environment like we care about our health, we pay more attention to it, do something every day, like use less one-off items, don’t litter the battery and so on. We all know how to do, and we just need more attention, it’s not about worry, but about love and care2.What causes poverty?For a person, I think the reason is they are lazy, they can’t insist on what they want, and they are coward, when the opportunity comes, they always sit in there and wait, but did not try to seize it, which lead to the absence of their ability, the poverty in mind result in the poverty in economy. For the whole society or a country, I think the reason is complex, and some are historical reason, take China for example, before China’s founding, the world war and anti-Japanese war make China lost many people and money, and after China’s founding, the cultural revolution make China’ economy go backwards at least 20 years. Also the lack of welfare and education is important reason, without the welfare, the poor guys lose the life guarantee, and many poor children don’t have a equal opportunity to receive education, and it becomes a bad cycle, and make the poverty more serious.3.Do you think women are discriminated against?To some extent, yes. Take China for example, many parents prefer to have a boy but not girl, because they think a married daughter is just like water has been poured and she doesn’t belongs to her parents any more. And during work, some company will discriminate the pregnant women,They might miss the opportunity or be replaced for they gave birth to a child and have a holiday. And sexual harassment is also a discrimination, it’s a disrespect to them. But I think maybe these thing still happen but our awareness are changing andman y people are working hard for it, like Emma Watson’s speech called “HeForS he”, and everything is getting better.4.What do you think about the one child policy?In my opinion, Itotally support this policy. Maybe giving birth to a child is a right to the parents, but considering the China nation condition, currently there are 1.4 billion people in China, and if the country don’t control the growth of population, it will become horrible and bring the environment more pressure, the problem of society will be amplified, food and other resource will be limited, so I think the one child policy is indispensable for now, but it’s just a temporary policy, along with social development, the policy will be change.5.Are illegal drugs a problem in China?Yes.the problem is st ill serious. And it’s still serious, one of the reason is that China neighbor the Golden Triangle, which is main opium producing area in the world, so many illegal drugs will flow into China. Furthermore, it’s new thing for youth and attract them, once they take drugs, it’s really hard for them to get rid of. Recently some news is also reported that some stars took drugs and caught like Jackie Chen’s son. And the benefit of selling drugs is attractive, making them a millionaire for just several month, so many people prefer to take that risk to sell drug and it’s hard ban thoroughly. So it’s still a serious problem for China.6.What can we do about pollution?About the pollution, there are still many things we can do. About 4 years ago, the classification garbage can was set on the street and in the school In China. But for now, these garbage can has lost its function it supposed to be. Classification is just a simple behavior, but it can recycle about 30% garbage, it’s what we can do. Somebody think that the pollution mainly cause by industry, but actually, according to a report, the Domestic pollution account for about 59% of total amount of pollution. So saving water and food, avoid using the one-off items to reduce waste is also important for environment. And talking about industry, we can also do something, when we find some factories discharge the polluted water or harmful gas, we can make a call to report to relevant department, it’s simple, but it’s effective.7.Should the government help poor people?Of course yes. Because I think many people become wealthy doesn’t mean the society do so, only when the poor people have more money to keep their life, our society can become prosperous. Besides, gap between wealthy and poor is still serious, which will cause the dissatisfaction of poor people and harm to social stability. So considering the social harmony, the government are supposed to help poor people.8.Should rich people help poor people?Yes. In my opinion, whether China or the west, helping each other is advocated. it’s a moral excellence. And obviously, the rich people have more money and influence power, they have more capacity to help the poor guys, they can use their money and power to create more chance for poor people. and maybe it’s al so a social responsibility for them, they become rich not only for their hard work but also depend on the whole society, so they are supposed to take that responsibility in return. So I think the rich people should help the poor people.9.Why are there so many wars?I think some wars happen because of the religion, but it’s very few, the most radical, important reason of war is the conflict of interest. There areno permanent friend between two countries but permanent interests. So countries need to warring to grab interests or protect interests. Take the war in Iraq as example, why the America pay a heavy price to attack Iraq, they said it’s for anti-terrorism, but maybe oil reserves in Iraq is the more important reason, so as long as the interests exist, it’s hard to stop the war.10.Should rich countries help poor ones?Yes. In my opinion, the rich countries do need to offer some help to the poor ones. To some extent, rich countries should take that international responsibility, they are not only help the country but also help millions of poor people, it’s humanitarianism. But as an old saying goes,a country does not have permanent friends, only permanent interests. And the help is helpful for two countries to build a closer relationship, which is also a chance for the rich countries to develop its foreigntrade. And this relationship also create more communication between two countries and make the common prosperity.11.What do you think about the death penalty for serious crimes?In my opinion, death penalty should be abolished because I think the penalty was to stop the crime and reduce the similar crime as a warn, so putting in prison is enough for these purpose.And death penalty is to kill a people, no matter he is criminal or normal person, life is precious and nobody can take one person’s life, and it’s also a crime too. besides, it’s hard to avoid that the court will also has the wrong judgement and some people are wronged, once the death penalty was executed, it can’t be redeem any more. So I totally hope to the death penalty can be abolished.12.What do you think about beggars?In my opinion, if the beggar has the ability to earn his life, he should not to choose to beg to earn his living. And people are not supposed to give them money because it won’t really help them but make them rely more on people’s giving. But if the beggar can’t earn his living by his own for he is disabled or too old to work, I will give money to them, and I will feel pity for them and feel sad for our country because it mean the country still lack the guarantee for people’s fundamental life, which force them to beg, so in this respect, if we hope the beggar would lessen, the country need to do more.。

The market for sports shoes and garments(服装) is very competitive. Phil Knight (Founder and CEO) is often quoted as saying that ‘Business is war without b ullets.’The war is especially intense(激烈) in today’s economic declination. Over the past years, Nike has gained its success partly from the competency at research and development, as is evidenced by its evolving and innovative product range. However, the income of the business is still heavily dependent upon its share of the footwear market. Nike has no factories. It does not tie up cash in buildings and manufacturing workers. They then manufacture wherever they can produce high quality product at the lowest possible price. Interestingly, consumers that wear Nike product do not always buy it to participate in sport. Some would argue that in youth culture especially, Nike is a fashion(时尚) brand. Nike actively sponsors(赞助) activities such as the World Cup (soccer) and The Olympics to gain reputation in emerging markets such as China.1.

(1 point)The strength lies in the advantages that accrue from work specialization. Results in economies of scale, minimizes duplication, satisfy employees etc. (2 points)but people tend to lose sight of the best interests of the organization as a whole; no one function is totally responsible for the results. (2 points)A company divides its department into accounting, hr, producing, marketing employed the functional structure. (2 point)Divisional structure is made up of self-contained units. (1 point)It focuses on results, frees the headquarters staff from being concerned with operating details; but the major disadvantage lies in the duplication of activities and resources. (2 points)Companies like GE and PepsiCo have the divisional structure. (1 point)4.What are Mintzberg’s managerial roles?

Staff authority functions to support, assist, advise, and generally reduce some of the informational burdens of those with line authority.pare and contrast authority and power.●Authority comes from the position, not the person.●Power is the ability of an individual to influence decisions, which may not be reflected in their levelof authority. French and Raven suggested five bases of power: reward, coercive, legitimate, referent, and expert.●Authority is a two dimensional concept while the power is a three-dimensional one. One shouldmove up in the hierarchy to gain higher authority, but in order to be more powerful, managers could move up or move inward to have closer relationship with those people representing the power core.3.set an example to clarify each of five types of departmentalization that are available. Departmentalization types examples (departments in certain organization)Functional marketing, HR, R&D, financing etc.Product food, clothes, home appliances, etc.Customer personal clients, government, VIP etc.Geographic Great China, North America, EUProcess validation, registration, payment, etc.4.What is a matrix structure? What is its primary strength? What are its major disadvantages?●Matrix structure—an organization in which specialists from functional departments are assigned towork on one or more projects led by a project manager.●Primary strength—can facilitate coordination of a multiple set of complex and interdependentprojects, while still retaining the economies that result from keeping functional specialists groupedtogether.●Major disadvantages—creates confusion and has a propensity to sponsor power struggles.pare functional and divisional structure.Both are bureaucratic design of organizations.●Functional structure groups similar or related occupational specialties together. While divisionalstructure is self-contained, composed of autonomous units or divisions, with managers having fully responsibility for a product or service.●Advantages of functional structure accrue from work specialization. 1. putting like specialtiestogether results in economies of scale, minimizes duplication of personnel and equipment; 2. itmakes employees comfortable and satisfied since they have same interests.Chief advantage of divisional structure is that it focuses on results, also it frees the headquarters staff from operating details so that they can focus on long-term strategic planning.●Weaknesses of functional structure: organizational interests might be lost in pursuit of functionalgoals; no one function is totally responsible for results; members become insulated and have littleunderstanding about peers in other functions.The major disadvantage of divisional structure is the duplication of activities and resources.。
