单选题These days a green building means more than just the color of the paint. Green building can also refer to environmentally friendly houses, factories, and offices. Buildings account for 65 percent of total U. S. electricity use. But green buildings can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, so that people can drive their cars less. That could be good for the environment, because cars use lots of natural re- sources such as gasoline, and give off pollution. Green buildings are often built on previously developed land, so that the buildings don't destroy forests or other wild habitats(栖息地). Marty Dettling is a project manager for a building that puts these ideas into action. The Solaire has been called the country's first green residential high-rise building. According to Dealing, "We've reduced our energy consumption by one-third and our water by 50 percent. Not everyone is leaping to move into a green building, however. Some people think that features such as solar panels cost more money than more traditional energy sources. Despite this, Dettling hopes that green buildings will become common in the future. "It's going to be big," she said.

单选题{{B}}Passage One{{/B}} When Columbus reached the New World, com was the most widely grown plant in the Americas. This plant's range extended from what is now southern Canada to lower South America. At that time some tribes cultivated it at sea level, others at elevation(海拔高度) of more than 11 000 feet. "Columbus had no way of knowing that corn was far more valuable than the spices(香料) and gold he had hoped to find." said Frances B. King, a professor at a university of Pittsburgh. Through human intervention, this plant has developed into several hundred races, or varieties. Their heights vary from 2 to 12 feet, and their maturity ranges from little more than 2 months to almost a year. Their ears vary not only in color, but also in size. Unlike other cereals(谷类), corn bears little resemblance to its wild ancestors. In fact, it differs from the appearance of its immediate ancestors more than any other cultivated plant known. From humble origins as a lowland grass, corn developed into the western world's important grain. As its high yields allowed communities to grow far beyond what early agriculture could feed, most scientists viewed corn as having largely fueled pre-Columbian growth and civilization. Now, new findings are greatly altering researchers' notions about the time when com revolution occurred. New dates for its emergence from Mesoamenrica do not support the widely held view. The evidence now suggests that the signs of corn in Americas can date back 5 500 years at least.

单选题Selling is the direct confrontation between the company and its customer. Management training and material tend to be devoted to “closing the sale”, "effective presentation skills", "use of visual aids" , and so on. The one aspect of selling which is often neglected is "prospecting(寻找可能的顾客)". In advance of any direct selling activity or, indeed, any promotion, it is important to take time and allocate resources to prospecting for clients. Prospecting identifies buyers and makes the best use of time available for selling. It is the quality, not the quantity, of prospects that matters. Market segmentation(条块化) will show the market segment most likely to yield buyers, e.g. manufacturing companies with a turnover in excess of ￡5 million within 50 miles of your offices. Building up a prime prospect file is the most valuable activity a salesperson can do. Once achieved, canvassing(游说顾客) is necessary only to "top up" the prospect reservoir when the level drops; that is, a prospect is converted to a customer, ceases to be a prime prospect and is replaced by another prime prospect. The prospect file will help only if it is kept up to date and used systematically. A follow-up or bring-forward system will force you to plan your time effectively. The selection of prospects can be done at the desk or by telephone. It involves a relatively low cost resource, compared with a field salesperson. The use of computers enables companies to develop a database of prospects which can be used interactively, depending on sales objectives or changes in strategy. By using a computerized marketing database, you can analyze important factors such as source of prospect/lead, date last called, change in staff. A new sales in a market sector can open the door to acquiring a number of new prospects in this sector.

单选题{{B}}16-20{{/B}} Two main techniques have been used for training elephants, which we may call respectively the tough and the gentle. The former method simply consists of setting an elephant to work and beating him until he does what is expected. Apart from any moral considerations this is a stupid method of training, for it produces a resentful animal who at a later stage may well turn man-killer. The gentle method requires more patience in the early stages, but produces a cheerful, good-tempered elephant who will give many years of loyal service. The first essential in elephant training is to assign to the animal a single mahout who will be entirely responsible for the job. Elephants like to have one master just as dogs do, and are capable of a considerable degree of personal affection. There are even stories of half-trained elephant calves who have refused to feed and pained to death when by some unavoidable circumstance they have been deprived of their own trainer. Such extreme cases must probably be taken with a grain of salt, but they do underline the general principle that the relationship between elephant and mahout is the key to successful training. The most economical age to capture an elephant for training is between fifteen and twenty years, for it is then almost ready to undertake heavy work and can begin to earn its keep straight away. But animals of this age do not easily become subservient to man, and a very firm hand must be employed in the early stages. The captive elephant, still roped to a tree, plunges and screams every time a man approaches, and for several days will probably refuse all food through anger and fear. Sometimes a tame elephant is tethered nearby to give the wild one confidence, and in most cases the captive gradually quietens down and begins to accept its food. The next stage is to get the elephant to the training establishment, a ticklish business which is achieved with the aid of two tame elephants roped to the captive on either side. When several elephants are being trained at one time, it is customary for the new arrival to be placed between the stalls of two captives whose training is already well advanced. It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions when it is eating normally, its own training begins. The trainer stands in front of the elephant holding a long stick with a sharp metal point. Two assistants, mounted on tame elephants, control the captive from either side, while others rub their hands over his skin to the accompaniment of a monotonous and soothing chant. This is supposed to induce pleasurable sensations in the elephant, and its effects are reinforced by the use of endearing epithets, such as 'ho! my son', or 'ho! My father', or 'my mother' according to the age and sex of the captive. The elephant is not immediately susceptible to such blandishments, however, and usually lashes fiercely with its trunk in all directions. These movements are controlled by the trainer with the metal-pointed stick, and the trunk eventually becomes so sore that the elephant curls it up and seldom afterwards uses it for offensive purposes.
