In current market, almost every enterprise have to face the fierce competetion to stay alive. Excellent service plays an important role in enhancing the company’s competence. There are many problems existing for companies to offer service. For instance, the service quality is poor or provided not in time, all of which cause bad effects on company’s image. Perhaps some companies will prolong their working time to solve such problems. However, I don't assume this solution can really eliminate these existing problems. Because extended time means employees will be forced to sarcrifice their leisure time, which might results in tention and far as I’m concerned, I think it is advisible to improve the quality of service instead of merely increase working time. For most customers, they put great attachment on the quality of service. For example, our national brand Haier offer excellent after- sale service, which have gained vast praise as well as , I think premium service can benefit both companies and the customers. Therefore, companies should pay more attention to the improvement of their service.我感觉你的要点太多，所以前两点写在第二段里，后两点写在第三段里，而且举了个海尔的

Cars in America(美国的汽车)Cars in AmericaCars are an important part of lifein the United States. The car made the UnitedStatesanationon helped to make the United States what it is are three main reasons why the car became so popular in the United States. First of all the country is a huge one and Americans like to move around in it. The cars provide the most comfortable and cheapest form of second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the United States as they are in other parts of the world. Nowadays there is a good system of air service provided by planes. But it is too expensive to be used third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don't like to wait for a bus, or a train or even a plane. They don't like to have to follow an exact the freedom a car gives them is what Americans want most to decrease of gas supplies has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas.美国的汽车汽车是美国生活的重要组成部分。汽车使得美国成为轮子上的国家，它也帮助美国成为现在的样子。汽车在美国如此盛行有三个主要原因。首先这个国家地域辽阔，而美国人喜欢在其间来回走动。汽车提供了最舒适最便宜的交通方式。汽车如此盛行的第二个原因是美国从未真正发展过有效廉价的公共交通这一事实。美国的长途火车从未像世界上其它地方那么普及。如今飞机提供了空中服务的良好体系。但是飞机太贵了，不能频繁使用。而第三个原因是最为重要的。美国人的独立精神是使得汽车盛行的真正原因。美国人不喜欢等公共汽车、火车甚至飞机。他们不喜欢必须遵循精确的时间表。汽车给予他们的自由正是美国人最想得到的。汽油供给的减少已经给美国人带来了巨大的问题。但答案不是发展更大型的公交体系。真正的解决方式必须是一种新型的汽车，那种不需要使用很多燃料的汽车。Car PollutionEach year there is an increasing number of cars on the roads as millions of new cars are produced. One out of six Americans works at making cars, driving trucks, building roads or filling up gas. Americans couldn't live without cars!Most Americans would find it hard to imagine life without a car. However, some have realized the serious problem of air pollution caused by cars. The polluted air becomes poisonous and dangerous to way to get rid of the polluted air is to make a car without pollution. But to build a clean car is easier said than done. Progress in this field is way is to replace car engines with something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model for prevent the world from being polluted by cars, we have to make some changes in our lives. Americans, for example, have to cut down on the number of their total are encouraged to use bicycles, which are thought to help keep the air this change does not come easily. A large number of workers may find themselves without jobs if a car factory cioses down. Thus the problem of air pollution would become less important than that of unemployment. Although cars have led us to a better life, they have also brought us new problems.汽车污染上路的汽车数量逐年增长，同时，每年都会生产出几百万辆新车。在美国，每六个人中就有一个从事与汽车相关的工作：造车、开车、修路、加油等等。离开汽车，美国人无法生活!大部分美国人简直无法想象没有车的生活会是什么样子。但是一些人也已经意识到汽车造成的空气污染已成为严重的问题。被污染的空气具有毒性，并且危害健康。解决空气污染的方法之一就是制造无污染汽车。但是生产清洁汽车说来容易做来难。目前，这一领域的进展十分缓慢。另一个方法就是使用其他东西替代汽车发动机。发明家正在研制蒸汽汽车和电车。但是许多厂家认为我们可以使用的实用型汽车的诞生可能还需要几年时间。要想阻止全球化的汽车污染，我们需要对自己的生活方式做出适当的改变。例如，在美国，需要缩减汽车总量。鼓励人们使用有助空气清洁的自行车。但这种改变不能一蹴而就。一旦汽车工厂关闭，就会有大量工人失去工作。与失业相比，空气污染似乎就不再那么重要了。尽管汽车为我们带来了更加舒适的生活，同时，它也带来了新的问题。
