单选题Money is a key element in economic and business activities and has been the theme of many witty remarks. Benjamin Franklin once wrote, "Money makes money, and the money 61 makes, makes more money." To most of us, money is 62 but the currency of a country. But to some people, money is 63 the best friend or the worst demon.

单选题The most exciting kind of education is also the most personal. Nothing can 61 the joy of discovering for yourself something that is important to you. It may be an idea or a bit of information you 62 across accidentally—or a sudden 63 , fitting together pieces of information or working through a problem. Such personal 64 are the "pay off" in education. A teacher may 65 you to learning and even encourage you in it—but no teacher can make the excitement or the joy happen. That"s 66 to you. A research paper, 67 in a course and perhaps checked at various stages by an instructor, 68 you beyond classrooms, beyond the texts for classes and into a 69 where the joy of discover and learning can come to you many times. 70 the research paper is an active and individual process, and ideal learning process. It provides a structure 71 which you can make exciting discoveries, of knowledge and of self, that are basic to education. But the research paper also gives you a chance to individualize a school assignment, to 72 a piece of work to your own interests and abilities, to show others 73 you can do. Waiting a research paper is more than just a classroom exercise. It is an experience in 74 out, understanding and synthesizing, which forms the basis of many skills 75 to both academic and nonacademic tasks. It is, in the fullest sense, a discovering education. So, to produce a good research paper is both a useful and a thoroughly 76 experience! To some, the thought of having to write an assigned number of pages often more than ever produced 77 , is disconcerting. To others, the very idea of having to work 78 is threatening. But there is no need to approach the research paper assignment with anxiety, and nobody should view the research paper as an obstacle to 79 . Instead, consider it a goal to 80 , a goal within reach if you use the help this book can give you.

单选题Are you interested in seeing the beautiful fall foliage of New England but tired of traffic jams and overbooked hotels? Then this year forget the crowds in New England and see the beautiful colors of autumn in the Catskills. These rugged mountains in New York State, just 90 miles northwest of New York City, are famous for the legendary tales of Rip Van Winkle, and more recently for the summer hotels mat sprang up in the region during the 1940s, 1950s, and 1960s. Families trying to escape the heat of New York City found the Catskills to be the perfect place to stay for a month or so each summer. By the late 1950s there were over 500 resorts and hotels offering nighttime entertainment as well as all kinds of outdoor activities. Famous comedies like Jackie Gleason, Joan Rivers, and Sid Caesar all got their start touring the hotel clubs here. Since the introduction of air-conditioning and cheaper air travel, however, families have stopped coming to the Catskills in such large numbers, chasing instead more distant locations at different times of the year. Many of the Catskills hotels closed in the 1970s, but some remain and have expanded and changed their facilities to meet the needs of today's visitors. Currently, there are many activities available to the traveler besides witnessing the changing colors of the leaves. There is an all-organic sheep farm where visitors can see how a traditional sheep farm operates. There are also hundreds of miles of scenic drives in the area. Route 42, for instance, is an excellent site for spotting bald eagles. For more information on vacations in the Catskills, call the office of Public Information.

单选题 Few creatures on earth are as cute as the black lion tamarin, and few have as dramatic a story line. Pug-nosed and diminutive, with a comic fringe of hair, these monkeys dwell in trees in small tracts of forest in southeastern Brazil. Or they did until 1905, when they were declared extinct. No one saw a black lion tamarin again in the wild until 1970. Later, in the 1990s, some Brazilian researchers turned up a small set of isolated, inbred populations scattered over a wide region. Since that time, they have been engineering tamarin migration, doing everything they can to save the world's most distinctive primates. Although they are no larger than house cats, tamarins have brains big for their size and a family life organized like our own. They live in groups anchored by an adult male andadult female, along with their offspring. When a mother bears young, she usually produces twins, and although members of the group share in their upbringing, it is most often the father who carries them around in the trees, where the families feed on fruits, insects and bird's eggs. Unhappily for the lion tamarins, their tree-bound niche began to disappear after the Portuguese landed in Brazil and began clearing forest to make room for Rio de Janeiro, the settlements and farms. As is the case for so many threatened species, the breakup of their habitat sounded the death knell for tamarins, depriving them of the continuity of forest they require to remain abundant and safe from potential threats in any single vicinity. The animals avoid predators by hardly ever coming down from the trees, so even a narrow logging road through a forest can begin the breakup by preventing them from moving from one patch of forest to another. A simple solution was to build bridges across roads, allowing the monkeys to move from one forest to another. With some lumber and the researchers' work, habitats that had been separated became continuous again, improving opportunities for migrating and mating. The next step was to broaden the distribution of the population. The researchers captured two families of black lion tamarins and moved them to a new forest. After a year, the moves were declared a success: Not only had 80 percent of the tamarins survived, but they had also produced new offspring. So far, so good. The researchers had learned the animals could adjust to the new habitats, even if the insects there tasted a little different or the trees were a slightly different size. The techniques for saving species in the wild vary. Species with less stringent habitat requirements, like wild turkeys, have been rescued by moving them into new settings as well as outlawing their killing. More challenging to preserve are species that require a lot of land, like elephants, and species that have highly specific requirements for habitat and prey -- like black-footed ferrets. Ultimately, as in all challenges, knowledge is power to save wild species from extinction.
