单选题"What does the middleman do but add to the price of goods in the shops?" The sentence comments on the middle operations between manufacturers and final customers. The middle action usually attracts a lot of attention from the public and the press. Generally speaking, the operation now talked about is what is often called wholesaling. The wholesaler buys goods in large quantities from the manufacturers and sells them in smaller parcels to retailers, and for this service his selling price to the retailer is raised several percent higher. For example, a wholesaler might purchase 5,000 pairs of work gloves and then sell 100 pairs to 50 different retailers. But his job is much more difficult because retail demand is not necessarily in accordance with manufacturers' production. Therefore, he adjusts or regulates the selling amount of goods by holding stock until required so that changing demand doesn't have an effect on the production, to some extent. Nonetheless, he has to bear the whole risk. The manufacturer can then keep up a steady production amount, and the retailer has no need to hold heavy stocks, who can call on the wholesaler for supplies any time. This wholesale function is like that of a valve (阀门) in a water pipe. The middleman also bears part of the risk that would otherwise fall on the manufacturer and also the retailer. The wholesaler provides a purely commercial service, for which he is well rewarded too. But that doesn't mean that it is the wholesaler who adds to the cost of goods. It is true that one could eliminate the wholesaler but one of his functions should be left: that of making sure that goods find their way to the people who want them. Some large wide-world famous discount chains, such as Wal-Mart Store and IKEA, serve as their own wholesalers. These companies go directly to factories and-other manufacturing outlets, buy in large amounts and then warehouse and ship the goods to their stores.

单选题Motivation is necessary in order to succeed. Whether you are working out to feel and look better, participating in the "Day of Silence" to support a cause, or working hard in school to get good grades and get accepted at one's college of choice, everything that people do has a motive behind it. However, motivation is a quality that many high school students seem to lack. Maybe it is because they feel as though the information that they are learning will never be useful to them, that they think their teachers are terrible, or that they simply "hate school." But no one else is forcing you to do your work. You've decided to take it on. It all comes down to what you want and what you are willing to do in order to get there. Minor setbacks often discourage people from trying. For example, if a student fails a French quiz, it could lead to him to not studying for a French test, and thereby not scoring well on it. Instead of allowing "feelings of inadequacy to get you down, think about all the things you do have and let those push you to succeed. Don't worry about or dwell on things that go wrong. Concentrate on your successes. Both UT Austin and Virginia Tech are readable and understandable websites for self help. The UT Austin site presents suggestions in bullet form and separates general motivation skills from academic ones. The Virginia Tech site also suggests ways to increase motivation, and then has a checklist. This list makes it easy for students to target the source of their poor motivation. Both sites seem to be aimed at college students, but they are perfectly suitable for high school students as well. Both websites were well presented and clear. However, in order to improve the Virginia Tech website, I would include a suggestion box after the checklist so after completing the list, after reading the suggestions from this box, one could have some sort of plan of action.

Standing on the rim of the Grand Canyon, gazing across this giant wound in the Earth's surface, a visitor might assume that the canyon had been caused by some ancient convulsion (剧烈震动). In fact, the events that produced the canyon, far from being sudden and cataclysmic (剧变的), simply add up to the slow and orderly process of erosion. Many millions of years ago, the Colorado Plateau (高原) in the Grand Canyon area contained 10,000 more feet of rock than it does today and was relatively level. The additional material consisted of some 14 layered formations of rock. In the Grand Canyon region these layers were largely worn away over the course of millions of years. Approximately 65 million years ago the plateau's flat surface in the Grand Canyon area bulged upward from internal pressure; geologists refer to this bulging action as upwarping; it was followed by a general elevation of the whole Colorado Plateau, a process that is still going on. As the plateau gradually rose, shallow rivers that meandered (蜿蜒而流) across it began to run more swiftly and cut more definite courses. One of these rivers, located east of the upwarp, was the ancestor of the Colorado. Another river system called the Hualapai, flowing west of the upwarp, extended itself eastward by cutting back into the upwarp; it eventually connected with the ancient Colorado and captured its waters. The new river then began to carve out the 277-mile-long trench that eventually became the Grand Canyon. Geologists estimate that this initial cutting action began no earlier than 10 million years ago. Since then, the canyon forming has been cumulative. To the corrosive force of the river itself has been added other factors. Heat and cold, rain and snow, along with the varying resistance of the rocks, increase the opportunities for erosion. The canyon rainfall running off the high plateau creates feeder streams that carve side canyons. Pushing slowly backward into the plateau, the side canyons expose new rocks, and the pattern of erosion continues.

单选题From her wheelchair, a child raises rounded arms above her head to form a blossoming flower. Nearby, a blind boy gently waves a flowing scarf as his body sways back and forth. Welcome to Infinite Dreams, a southern California program that each year helps more than 1,000 children with disabilities learn ballet, jazz, and other forms of movement. For founder Zina Bethune, a professional dancer and actress who works with a team of six instructors, this is a deeply felt mission. "I've walked a very fine line between the abled and disabled worlds all' my life," says Bethune, a former soloist with the New York City Ballet who starred on Broadway in Tommy Tune's production of Grand Hotel. Born and raised in New York City, Bethune, 47, started formal ballet training at age 6 with legendary choreographer George Balanchine. But during adolescence, a host of medical problems mined her chances of becoming a prima ballerina. But she ignored them and her pain and continued to dance. Faced with all sorts of difficulties, she never gave up. By the time she was 34, Bethune had went gone two hip replacements. Bethune, who has been married for 18 years to a former dancer, started Infinite Dreams in southern California in 1983. "Dance is spiritual," she says. "And these children's spirits are not disabled." Funded through grants and private donations, the group offers hour-long weekly sessions in schools and performs at arts festivals throughout the year. "Participation, not perfection, is emphasized," notes Bethune, who is currently trying to make her program available nationally. Adjustments to the dance steps are made as needed. Russell Bartel, 14, a star student with spina bifida and little feeling in his lower legs, pirouettes not by turning on his toes but by spinning on his back. "What we try to make clear," Bethune says, "is that their individual version of any step is valid. That's their dance." From that understanding often springs a newfound sense of confidence. "I can do a lot more than I ever thought I could." Bartel says. "It makes me feel great./
