第4题：
Some young soldiers who had recently joined the army were being trained in modern ways of fighting,and one of the things they were shown was how an unarmed man could trick an armed enemy and take his weapon away from him．First one of their two instructors took a knife away from the other,using only his bare hands;and then he took a rifle away from him in the same way．After the lesson,and before they went on to train the young soldiers to do these things themselves,the two instructors asked them a number of questions to see how well they had understood what they had been shown．One of the questions was this:“Well,you now know what an unarmed man can do against a man with a rifle．Imagine that you are guarding a bridge at night,and that you have a rifle．Suddenly you see an unarmed enemy soldier coming towards you．What will you do?”
The young soldier who had to answer this question thought carefully for a few seconds before he answered,and then said,“Well,after what I have just seen,I think that the first thing I would do would be to get rid of my rifle as quickly as I could,so that the unarmed enemy couldn't take it from me and kill me with it!”

问答题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.解析： 暂无解析 -

问答题Practice 7 A: What is important when...? Maintaining customer interest in a company’s products ●Quality goods ● Excellent after-sales service ●Feedback B: What is important when...? Considering transport management ●Timing ●Cost正确答案： 【参考范例】
If you choose A:
As everyone knows, it is of great importance for a company to maintain customer interest in their products, which can help the company keep the sales increasing. I think a company should make every effort to retain its current customers. First, it should always confirm that it provides its customers with quality goods and good after-sales services. Second, it should place enough emphasis on the feedback from its current customers and take prompt action to meet their needs and demands. Third, if possible, some incentives to its old customers should be provided to maintain this part of customers. All in all, a company should try every possible way to keep its current customers who are satisfied with its products and services, and meanwhile it should stay ahead of the market.
If you choose B:
Any distribution of products from producers to whole-salers or from wholesalers to retailers requires transportation. Sometimes, the cost of transporting some products can outnumber the cost of producing them. Therefore, an efficient form of transportation can give rise to lower costs and higher profits for the company. For each form of transportation, timing, cost, and availability should be estimated. This assessment permits the company to choose an optimal method of transportation. The most common forms of transportation used to distribute are truck, rail, air, water, pipeline.解析： 暂无解析 -

问答题Practice 2 A: What is important when...? Choosing a business-training course ●Fees ●Size of group ●Subjects covered B: What is important when...? Choosing a magazine to buy regularly ●Contents ●Cost ●Printing quality正确答案： 【参考范例】
If you choose A:
When choosing a business-training course, first of all I’d like to see if our company could afford the expenses. If the business training course is too costly, the company will have to reconsider the value and effect of that course.
In addition, the size of the goup shoud also be considered. If I were the decision-maker, I would select a small-sized group. Size of group will determine the quality of training to a great extent. A small group will provide each trainee with more opportunities.
Subjects covered also need to be noticed. If the training course covers a wide range of subjects, it will be instructive for the trainees in different aspects, since the more subjects are covered, the more knowledge they will gain.
If you choose B:
When choosing a magazine to buy regularly, contents are the first thing to consider. It is for sure people will look at what’s in a magazine before they decide to buy it. To a large extent, the quality of a magazine depends on its contents.
Another factor is the cost. The cost of a magazine will stir up warm response from the market. If the cost is relatively lower than that of the same category, as a rule, readers would prefer the cheaper one.
In addition, printing quality is the face of a magazine. Generally, copperplate printing is widely applied to high grade magazines, for low cost plain paper would downgrade their images.解析： 暂无解析 -

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.解析： 暂无解析 -

问答题Practice 7 Task Sheet: A: WHAT IS IMPORTANT WHEN...? Aiming to improve career prospects ● Reading business articles ● Learning a foreign language ●…______ B: WHAT IS IMPORTANT WHE...? Deciding how to transport goods ● Destination ● Speed______ ●… C: WHAT IS IMPORTANT WHEN...? Purchasing new machinery ● Level of automation ● Maintenance requirements ●…正确答案： 【参考范例】
If you choose A:
When aiming to improve career prospects, you need to realize the importance of reading business articles. You need to understand what is going on in the business world, what is the latest trend in making deals. Learn more about financing and the industry you are in. Try to familiarize yourself with more management skills concerning time management, project management, HR management, PR management, etc.
Secondly, learn a foreign language will also help improve career prospects. Grasping a foreign language means that better communication with foreign investors and clients. You will be able to read business articles published in foreign newspapers/magazines. When attending international conferences, you will have no problem in understanding keynote speeches at such conferences.
If you choose B:
When deciding how to transport goods, first of all, you need to figure out how far away the destination is so that you can better decide on the means for transporting goods. For instance, shipping is often considered the most economical way to transport goods of large quantities to far destinations. As the express highways develop rapidly in our country, transportation by truck has won increasing popularity as it can offer door-to-door delivery services for most destinations within the country.
Another factor to be taken into account when deciding how to transport goods is speed. Although the fastest way is by air, transportation by air has also its disadvantages since it is more expensive than other means of transportation and transporting goods in very large sizes is very difficult.
If you choose C:
When purchasing new machinery, it is important to know about the level of automation, that is whether it is fully automated or partly automated. In case that it is only partly automated, you need to think about how to operate it and whether the workers need to be trained to operate it. If it is necessary to offer some training, you need to consider the selection of trainers. Moreover, the training cost and who will pay for it needs to be taken into consideration.
Furthermore, it is necessary to know whether it is easy to maintain the machinery and the relevant requirements, like how often does it require a routine maintenance check, how often does it require an overhaul, whether it is easy to get spare parts or replacement parts, whether spare parts are included in the overall price for the machinery, etc.解析： 暂无解析 -

问答题Practice 4 A: What is important when...? Choosing a conference center ●Facilities ●Accommodations ●Location B: What is important when...? Selecting an employee ●Qualification ●Personality ● Creativity正确答案： 【参考范例】
If you choose A:
When choosing a conference center, it is of vital importance to consider the facilities, since facility available is the hardware component of a conference center. If the facility is in condition,, our work won’t be held up.
Moreover, accommodation is another important matter. As a complex building, a conference center should cater to daily necessities, providing the guests with satisfactory food and bedrooms, which would leave them a pleasant recollection.
At the same time, location is a decisive factor for business. For a conference center, company-intensive downtown area would be an ideal choice. However, there’s also a trend of moving towards tranquil suburbs.
If you choose B:
When selecting an employee, we should check on his or her qualification first. Certificates and diplomas can be referred to, since they reflect the extent to which the candidate receives education. However, they do not necessarily stand for a candidate’s qualification. We’ve met with too many incompetent holders of advanced degrees in real life. It is unrealistic to depend on them to make a profit for the company. On the contrary, interviewees with practical experience would bring in more benefits for the company.
The second factor is the personality of the candidate. Everyone has a unique personality, which is a welcome phenomenon. However, a group of staff with similar personalities will meet with far less internal conflicts. Yet, there’s also a problem to worry about, since this unit might become a stagnantworking place where there is no room for vitality in the long run. Therefore, what is needed is a balance.
Moreover, we should attach great importance to an employee’s creativity. Mediocreyesmanwho is accustomed to echoing the views of others clearly belongs to redundantlabourer. The employee is expected to have innovative ideas and be creative.解析： 暂无解析 -

问答题Practice 6 A: What is important when...? Keeping excellent staff ● Attractive salary ● Comfortable company culture ●Opportunities to improve B: What is important when...? Selling a new product ●Discount ●Quality ● Advertising正确答案： 【参考范例】
If you choose A:
Firstly, the reward of a job is absolutely vital to many experienced staff for they made great contribution to the company. So an attractive salary is necessary. Otherwise, why would they apply themselves to piles of documents and pages of codes? Providing an attractive salary is very important to keep excellent and experienced staff.
Secondly, it is also sensible to form a relaxing and comfortable company environment for the staff. Working five days a week means that they spend quite a large part of their time in the company, and it is apparent that a pleasant atmosphere will be quite attractive.
Thirdly, companies can’t afford to neglect giving staff opportunities to improve their professional skills and other comprehensive abilities. Otherwise, staff will be concerned that one day they would be out-dated in terms of skills.
If you choose B:
When selling a new product, discounts should be taken into account. By giving his counterpart a favorable discount in selling a new product, a dealer will be able to reach an agreement with the other party more easily. .And their volumes of transaction are more likely to grow larger.
In addition, quality is equally important. As the life of the product, quality is a decisive factor. Mediocre products will damage the company’s reputation, and cause a loss of consumers at last.
Furthermore, an ingeniousadvertising campaign will catch the eyes of the masses due to the daily ad bombardment in their everyday lives.解析： 暂无解析 -

He or she also need to be familiar with the special terms and jargons for commercial negotiations, finance, law and so on. .
What’s more, the interpreter should be reliable. That is to say, he or she must be punctual for the meetings, keep information learned at the meetings confidential and interpret what is being discussed as accurately as possible.
If you choose C:
When introducing a new product range onto the market, timing is very important. The introduction should be made at an appropriate time, for instance when the market is matured for having this new product range, by which means there will be prospective customers for the products. In case that similar products are to be introduced onto the market by competitors, make sure that the introduction is made ahead in order to grab the utmost possible market share.
Furthermore, advance publicity is necessary for its significant role in paving the way for the introduction. Advance publicity can be implemented in a variety of ways. For example, hold a news conference to declare the introduction, do some advertising on TV/radio, in newspapers/magazines, or send samples of the new product to potential customers’ houses, etc.解析： 暂无解析
