2.共用题干 第二篇A Very Slow RideThe surface of the earth may seem very stable to you.But you might be amazed if you knew some of the things that are going on under that surface.The earth has an outer shell of rigid pieces called tectonic plates(地壳构造板块).The plates include both ocean floor and dry land.Some have whole continents on top of them. The continents on top of the plates are just going along for a slow ride,moving only about four inches per year. But even this small movement causes three types of big interactions.One type is ocean ridges.These ridges develop in places where two plates are moving away from each other. As the plates separate , hot magma(岩浆)flows up to fill the space. New crust(地壳)builds up on the plate boundaries and causes ocean ridges. These ridges form long mountain ranges,which only rise above the ocean surface in a few places.Another type of reaction-trenches-occurs between two plates that are moving toward each other.As the plates meet,one bends downward and plunges underneath the other. This forms deep ocean trenches.The Marianas Trench off Guam in the western Pacific Ocean has a depth of more than 36,000 feet.This is the lowest point on the ocean floor. If the leading edges of the two colliding plates carry continents,then the layers of rock in the overriding plate crumple(变皱)and fold. A plate that carried what is now India collided with the southern edge of the plate that carried Europe and most of Asia.This caused the Himalayas,the world's highest mountains.The third reaction is transform faults(转换断层).These faults occur where two plates that are traveling in opposite directions slide past each other.Severe earthquakes can occur. The San Andreas Fault in California is a good example of this type of movement.The San Andreas Fault is an example ofA:a severe earthquake.B:a California rock formation.C:two plates moving apart.D:two plates sliding past each other.

    Practice 2   (The candidate chooses one topic and speaks about it for one minute.)  A Promotion: how to develop a promotion program for a new product.  B Recruitment: how to recruit a new sales representative.  C Training: what are the goals of a training program for sales representatives.

    正确答案: 【参考范例】
    If you choose A:
    To develop a promotion program for a new product involves various aspects, each of which requires careful planning. First of all, we should identify the target audience of the program, since different ways of promotion apply to different groups of audiences. As far as the product is concerned, characteristics of it and the brand image should be taken into consideration. Secondly, we must establish a specific communication objective, which will help to find effective ways to arouse customers’ awareness of the new product. As for budget, it should also be taken into fully account. It has to be ensured that the expenditure of the program is within the advertising budget. Thirdly, given the above consideration, communication channels need to be decided. It is vital to select a proper media for advertisements. Since pricing strategy plays a key role in the promotion program, it must be made carefully. At last, make sure to collect information on initial stages in time from the market, which will provides us with the main resources to make an evaluation of the feedback from the market.
    If you choose B:
    Several steps need to be taken in order to recruit a new sales representative. First and foremost, the selection standards need to be set. For instance, what kind of education background should the applicant have? How many years of working experience must he or she has? Criteria of this kind in the preliminary selecting process are very significant. What should draw our equal attention is that the applicant should be a person with an extrovert personality. He or she is expected to be hard-working, convincing and persuasive in order to meet the goal. Next, appropriate channel should be chosen to make those potential applicants well informed of the job opportunity. Job fair, head-hunter and campus interview are all good options. Last but not least, a face to face interview is indispensable to assess the applicant’s ability to communicate, as well as his or her general competence to do the job. Besides, a comprehensive appraisal of the applicant is strongly recommended.
    If you choose C:
    The objectives of the training program for the sales representatives are various according to different needs. First of all, some brief information about the company should be offered, for example the company’s history, organizational structure, financial structure and so on. It is also necessary to emphasize the current situation of the company. Sales representatives must have a good understanding of the company’s main products, its annual sales volume, the sales target of this financial year and something of that kind. Secondly, sale representatives should also be given a brief introduction of the people in the company, such as are the chief officers of the company, immediate managers in the representative’s department as well as colleagues in his or her working group. Finally, it comes to customers. We should put high value on the types and characteristics of the customers. It is also expected that their needs and wants are exactly transmitted to the sales representatives. With that kind of information in mind, the sales representatives will become more adaptive when selling products.

    Practice 2  ‘Mini presentation’—about 6 minutes  In this part of the test you are asked to give a short talk on a business topic. You have to choose one of the topics from the three below and then talk for about one minute. You have one minute to prepare your ideas.  A  WHAT IS IMPORTANT WHEN…?  NEGOTIATING  ● COMPROMISE  ● DISPUTE  ●...  B  WHAT IS IMPORTANT WHEN…?  EMPLOYING TECHNICAL WRITERS  ● BEING ABLE TO WRITE WELL  ● MEETING TIGHT DEADLINES  ●...  C  WHAT IS IMPORTANT WHEN…?  MANAGING A COMPANY  ● COMMUNICATION  ● EXECLLENT MANAGER  ●...

    正确答案: 【参考范例】
    Mini-representation One:
    I think when managing a company one of the most important features is communication. Good communication is necessary at all stages of the business process, which can contribute to a successful business.
    Within individual companies internal communication occurs at, and between the various levels. Directors communicate with one another in term of the company’s overall strategy. They inform managers of their plans, and the managers then communicate with other employees to convey their messages. Negotiations are conducted with regard to pay and working conditions. Managers express their decisions and orders through good communication, which can achieve the aim of  improving morale and motivation. Employees also communicate with each other, for example, over production, wages and their spare activities.
    Reliable and effective communication is one of the key elements which lead to efficient management of a company.
    Question: Can you tell me other vital elements which result in efficient management of a company?
    Answer: Many requirements are important for the efficient management of a company, both internal and external. We need good communication, good staff and managers, smooth flow of the capital, the full cooperation between the company, etc.
    Mini-representation Two
    Firstly, it is of very importance to be able to write well. This means not only knowing the basic rules of spelling, grammar and punctuation, but also having the competence to condense and organise sophisticated information to make it accessible to the public. A good writer must also be capable of dealing with meeting tight deadlines. Secondly, as far as career prospects are concerned, after acquiring valuable experience, many technical writers have the opportunity of working on managerial roles. They may then have the responsibility for the work of other writers within a particular company, or they may prefer to become contractors. This means selling their services through an agency employing many freelance technical writers, whose services are charged to companies at an hourly rate.
    Question: What do you think which factor is more significant, being able to writer well or meeting tight deadlines? Why?
    Answer: I think neither of them can be ignored. We need technical writers not only being able to write well but also being competent to meet tight deadlines.

    问答题
    题目要求:  In this part of the test, you are asked to give a short talk on a business topic. You have to choose one of the topics from the three below and then talk for about one minute. You have one minute to prepare your ideas.Practice 1  (The candidate chooses one topic and speaks about it for one minute.)  A How to negotiate successfully when we are in business?  B In business, what important role does the communication take?  C What kinds of skills shall the technical writers have?

    正确答案: 【参考范例】
    If you choose A:
    It is a key skill in any business to negotiate successfully so as to reach agreements with other people or parties. The negotiation could be done with a buyer or a seller and it will always involve an element of compromise, no matter what. But, when entering negotiations, it is important to keep in mind that to negotiate and make agreements successfully is almost impossible unless you think you can afford to ‘lose’ or walk away from on offer. The result will be you avoiding asking more than what you suppose the other side will give without a dispute. Consequently, you will become a passive observer, while the other side will dictate the terms.
    If you choose B:
    Communication is one of the most important features in any business. Good communications are indispensable at any stage of the business process.
    Within individual company, internal communications happen at, and between the different levels. Directors will communicate with one another with regard to the company’s overall strategy. They communicate their plans to managers, and the managers then inform the other employees. Negotiations are usually conducted in terms of payment and working conditions. Managers try to boost morale and motivation with good communication. Employees also communicate with one another, over certain matters, for instance production and wages.
    Reliable and effective communication is instrumental when it comes to efficient management of a company.
    If you choose C:
    Firstly, technical writers should be able to write well, which means more than just knowing the basics of spelling, grammar and punctuation. The ability to condense, organize and generalize complicated information to make it easier to understand is also very important. A good technical writer must also be capable of handling tight deadlines. As far as career prospects go, with the valuable experience gained, many technical writers actually have the chance to take on management roles. Then they will be responsible for the work of other writers within a particular company; or they may want to become contractors, in other words, selling their services to companies at an hourly rate through an agency which employs many freelance technical writers.

    Practice 5   (The candidate chooses one topic and speaks about it for one minute.)  A Advertising: the importance of using celebrities to endorse products  B Human Resources: how to retain high achievers on a company’s staff  C Business Strategy: the factors involved in influencing market trends rather than reacting to them

    正确答案: 【参考范例】
    If you chose A: (three possible answers)
    a. Many factors will influence consumers’ choices and desires, which are constantly changing, according to their needs and styles that have caught the popular imagination. Sellers of goods and services court, entice, and implore consumers. Using celebrities to endorse products has been one of the most effective advertising gimmicks. People tend to think negative advertising does not sway them but the truth is that it does. A great number of people always copy celebrities’ behavior. Celebrity endorsement serves a model for community.
    b. Using celebrities to endorse products is very important for advertising. If a celebrity endorses a product or service, he or she says that they use and like it in an advertisement. Celebrity endorsements show their formal support or approval for someone or something. If a famous person buys a product, many consumers tend to follow. It is even more so, when consumers are not confident enough about their ability to identify exactly what it is.
    c. The reason why many people always do the same as the famous people have done is that they trust celebrity. Although they may distrust advertisement, they will possibly trust the celebrity. Celebrities’ behavior has a great effect on consumers. Therefore, using celebrities to endorse products is beneficial to the company, for it gives the company an advantage, improves its reputation, and helps the company promote sales. Therefore, it is very significant for companies to use celebrities to endorse products, in advertising.
    If you chose B: (two possible answers)
    a. Retaining high achievers on a company’s staff has been used as a market-driven approach to talent retention. Although once rare in business, open competition for other companies’ people is presently an accepted fact. Fast-moving markets require fast-moving organizations to be continually refreshed with new talent. However, no one will be willing to see talent leave; whenever a good employee walks, the business takes a hit. It’s useless to hope that by tinkering with compensation, career paths, and training efforts, you can wall off your company from today’s labor market.
    b. Besides monetary compensation, an alternative to retain high achievers on a company’s staff is a market, which is a driven approach to retention based on the assumption that long-term across-the-board loyalty is neither possible nor desirable. By trying hard to figure out which employees you need to retain and for how long, you can take advantage of highly targeted programs to keep the required talent in place. Most companies today depend on compensation to build loyalty, which is only one of many effective retention mechanisms. Jobs can be redesigned to reduce turnover. For example, UPS retain many more drivers by shifting the tedious and laborious job of loading trucks to other employees.
    If you chose C:
    I think the factors involved in influencing market trends are as follows: Consumer, Cost, Convenience, and Communication. The key difference is that under modern marketing, profits are regarded as a function to provide customer benefits, whereas under the old marketing, profits were seen as a function of sales. To conclude, marketing is a concept, a business process as well as a set of activities. This total set of marketing activities, integrated into a unified program, are sometimes called the marketing mix, which today, in addition to profitability, typically includes a lot of broader objectives relevant to current social concerns. These concerns now concentrate on areas like protection of the physical environment, product safety, and equal employment opportunity.

    Practice 4  ‘Mini presentation’—about 6 mimes  In this part of the test you are asked to give a short talk on a business topic. You have to choose one of the topics from the three below and then talk for about one minute. You have one minute to prepare your ideas.  A  WHAT IS IMPORTANT WHEN…?  Analysing project feasibility  ● Market research  ● Implementation of the project  ●…  B  WHAT IS IMPORTANT WHEN…?  Dealing with cost control  ● Monitor asset usage  ● Improve productivity  ●…  C  WHAT IS IMPORTANT WHEN…?  Promoting a new product  ● Distribution channel  ● Perfect timing of launching  ●...

    正确答案: 【参考范例】
    If you choose topic A
    As far as I am concerned, market research should be carried out before starting any project. It is evident that the needs of the consumers should be considered brfor the launching of any project . If a certain product is abundant in the market, it can be a bad idea to make more of that kind of product. On the other hand, if people have certain needs of some products, it is the perfect time to design the projects for a good market will be there.
    Of course, it is only with appropriate implementation can a positive impact be achieved., after the design is completed. For instance, financial support and well-trained personnel should be taken into consideration when implementing the project.
    Furthermore, profitability analysis is another factor to consider. Before we carry out any project, we should do some profitability analysis. A lot can be revealed from studying economic indicators. Economic indicators mean the consumer confidence index, employment cost index, producer price index, consumer price index and so on. All of them will show the prosperity of market.
    If you choose topic B
    The completion of production and the profit of the company is closely connected with cost control. We should make a through calculation of monitor asset usage as well as the productivity and unit labor cost to make full use of all the assets. Improving the production line will be a good way to improve productivity, which will reduce the storage time and save money. As for asset usage, it will be wise to monitor if every piece of them is fully used.
    We can also try to find substantial material for the sake of reducing the cost .By doing this, we can also ask for discount from the supplier. I am sure they will give favorable discounts to regular customers.
    The participation of all the employees will be needed in terms of cost control. Actually, every section can contribute in one way or another. For instance, by improving their professional skills the accounting staff can help with the cost control. All in all, the well-being of the company needs the efforts of every section.
    If you choose topic C
    When promoting a new product, we should consider several factors. First of all, the distribution channel of the product is of prime importance. It is suggested that the designing of the whole promoting campaign be based on that. In other words, it is a choice of designing a universal way to advertise the product or allowing the retailers to do it their own way.
    Secondly, perfect timing of the launching is also very significant. If there is the crash of similar products promoting in the same season, never take it lightly. An overflow of the product into the market is very likely to happen..
    In addition, an appropriate media in promoting new products also means a lot. If a right media is chosen, target consumers can access the advertisement of the new product much easier., Besides, different strategies can be applied when different products are to be advertised. For instance, we can think of some new way to make the product known and accepted.

A  WHAT IS IMPORTANT WHEN MOTIVATING STAFF?  ● FINANCIAL BENEFITS  ● CAREER DEVELOPMENT OPPORTUNITIES  ●...  B  WHAT IS IMPORTANT WHEN SATISFYING CUSTOMERS?  ● A GOOD AFTER-SALES TEAM  ● MORE CUMMUNICATION WITH CUSTOMERS  ●...  C  WHAT IS IMPORTANT WHEN PREPARING FOR A JOB INTERVIEW?  ● STUDYING THE JOB ADVERTISEMENT  ● STUDYING THE COMPANY  ●...

    正确答案: 【参考范例】
    Sample A:
    Well, I’m very interested in this topic—what’s important when motivating staff. As far as I am concerned, I think we should take three main important factors into consideration, that is, financial incentives, career development chances and an easy-going boss. Firstly, the most important factor should be the financial benefits. They may consist of good salary, bonus and other perks. As we know, instead of working for fun, most people work to live. And also as the saying goes, money can make the mare go, thus money is very important in develop staff’s motivationm. Secondly, career development chances are quite important. In reality, there is nobody who does not want to be promoted. If there are not any good career prospects in a job, staff will probably give up the job. Finally, an easy-going boss is also important. Nobody is willing to work with a difficult boss. In conclusion, financial incentives, career development chances and an easy-going boss are important in motivating staff.
    Sample B:
    Well, I’d like to talk about the important factors that are beneficial to improve customers’ satisfaction. Firstly, we need a group of outstanding after-sales service team. It is true that it is difficult to meet the demands of every customer, but our duties involve dealing with customers’ complaints and trying all manner of ways to solve their problems. In order to cultivate an efficient group of after-sales service team, we must arrange some staff training courses. Besides, we need to conduct researches on customers about whether they are satisfied with our products and in what aspects they are dissatisfied. On the basis of the result of the researches, we can make improvement. In a word, a excellent after-sales team and more communication with customers  can help improve customer satisfaction.
    Sample C:
    The objective of my talk is how to prepare for a job interview. I think the preparation mainly consists of studying the job advertisement, finding out information about the company and preparing yourself psychologically. First of all, you should study carefully the job advertisement so that you can match your qualifications, such as knowledge, abilities and skills, with the specifications required for the vacancy. You must make the interviewer believe that you have all the qualifications required, thus you are the right kind of person they are looking for. Secondly, you should know more about the company, for example its profile, requirements, existing problems, structure, campaigns and future plans. Finally, you should also prepare yourself psychologically and this will help you overcome stress. For example, rehearsing the interview with your friends is a good way of relaxation exercise that can put confidence in you.

    Practice 3  “Mini presentations”—about 6 minutes  In this part of the test you are asked to give a short talk on a business topic. You have to choose one of the topics from the three below and then talk for about one minute. You have one minute to prepare your ideas.  A: WHAT IS IMPORTANT WHEN...?  Selecting staff for overseas training:  ● Work experience  ● Command of the language of the target country  ●...  B: WHAT IS IMPORTANT WHEN...?  Conducting a market analysis:  ● Targeted customers/clients  ● Comparison with major competitors  ●…  C: WHAT IS IMPORTANT WHEN...?  Aiming to improve customer service:  ● Finding out customer needs  ● Dealing with complaints efficiently  ●…

    正确答案: 【参考范例】
    If you choose A:
    When selecting staff for overseas training, their work performance must be taken into consideration. Selecting staff members with outstanding work performance for overseas   training will set a good example for other staff members, which may encourage them to   improve their work performance.
    Moreover, it is also very important to consider their command of the language of the target country when selecting staff for overseas training. Staff members with a good command of the language of the target country will be able to understand instructions given by the overseas trainer well enough, participate in all training activities without language barrier, and communicate with the trainer or other trainees freely.
    If you choose B:
    When conducting a market analysis, it is very necessary to analyze the targeted customers/clients. This analysis may include collection and analysis of information about the targeted customers/clients in terms of gender , range of age, likes and dislikes and average income.
    Furthermore, it helps to make a comparison with major competitors providing same or similar products/services.  There are several aspects that may be compared, for instance, financial strength, cost efficiency, impact of advertising, product/service range and special features of products/services.
    If you choose C:
    When aiming to improve customer service, first of all we should find out customer needs. Different approaches can be taken to collect information concerning customer needs, for example, designing a questionnaire for collecting most information, training a team for collecting and analyzing the information, etc.
    In addition, dealing with complaints efficiently is also very important, which can be done in a variety of ways.
    We may set up a hot line for customers to make complaints and train a team for handling customer complaints. The members of the team should be patient, enthusiastic and have good telephone manners and interpersonal skills.
    It means a lot that every complaint is dealt with seriously by the team and the customer who makes a complaint is always informed of the final result.
    It is advisable that a record of all complaints made by customers and how they have been dealt with be kept so that effective ways can be suggested as for how to deal with these complaints.

    问答题
    题目要求:  In this part of the test, you are asked to give a short talk on a business topic. You have to choose one of the topics from the two below and then talk for about one minute. You have one minute to prepare your ideas.Practice 1  A: What is important when...?  Attending an interview  ●Punctuality  ●Manner  ●Appearance  B: What is important when...?  Working in a team  ●Having a team leader  ●Deciding people’s responsibilities  ●Sharing information

    正确答案: 【参考范例】
    If you choose A:
    When attending an interview, it’s a merit that we show up on time. For an interview due to start at nine thirty in the morning, the candidate is expected to arrive five minutes earlier. To be better prepared for the interview, if possible, he’d better pay a visit to the interview site in advance. By doing this, he will be able to figure out the shortest route and the approximate time to get there.
    In addition, remember that the interviewer is observing you even before your entrance into the room. Therefore, don’t forget to knock at the door first, no matter whether it’s shut or open. Furthermore, eye contact is necessary. Look straight into the interviewer’s eyes with politeness and self-confidence. At the meanwhile, greet him with a smile
    Furthermore, a person who is particular about his appearance is always welcome everywhere. With your hair neatly cut your beard nicely shaved and your face cleanly washed, you are more likely to leave a good first impression. At the same time, arm yourself with a starched shirt, an ironed suit and a pair of polished shoes. By doing that, you’re definitely a pleasant guy in the eyes of both male and female interviewers.
    If you choose B:
    When working in a team, first of all, a team leader is essential for the team. With the lead of a good team leader, the team can fulfill the tasks smoothly. Without a team leader, there will be no definite direction and employees may not know what to do and how to do the work in co-operation with each other.
    Secondly, it is important that every employee knows his/her responsibility. When clear-cut assignment of responsibility, employees can concentrate on their tasks and work more efficiently. As a result, the company’s objective can be eventually achieved.
    Thirdly, as a member of the team, every employee is entitled to know any information within the group. Therefore, information should be shared, and by doing this a lot of time and energy can be saved, which may otherwise be used to do much more work.

    正确答案: I’d like to talk about the guy I met during my internship at a local station. We were both working at the evening news section. His name was Jack and he was responsible for news editing while I was the assistant of the chief editor. On the first day of work, I simply spin around with lots of paper materials and tapes in my hands and couldn’t find my way. Jack leaded me to the office and helped me work out those papers. He was very competent and responsible. Besides, he was outgoing and warm-hearted with a big smile on his face. He was really a nice guy to work with. Before long, he became very popular among all the colleagues. Everybody enjoyed talking to him and being around him. I liked working with him too. He would strive to solve others’ trouble.
