单选题For those anxious about committing to a master's degree, there is the post-baccalaureate (学士后) certificate. Usually a four- to seven-course, self-contained certificate provides 25 academic study, or job-specific skills training, with a minimum 26 of time and money, and potentially significant payback. Nearly 51000 people earned the certificate in 2010—a 46 percent increase in five years. For men, having the certificate adds an average 25 percent in earnings; for women, who tend toward less 27 fields such as teaching and health care, the 28 is an average 13 percent, according to research from Georgetown University's Center on Education and the Workforce. About 3 percent of the workforce—or 4 million workers—have certificates. Certificates are market-driven. Colleges and universities, alert to evolving workplace requirements (and business opportunities in higher education), 29 gaps in education and training that appeal to adult students looking for a way to stand out or retool (重新安排) their careers. In some fields, especially health care, education, counseling, engineering and technology, certificates provide compulsory training for certain jobs or promotions, or make one 30 for higher pay scales. In other fields (arts management, interior design, public relations), the certificate shows interest and acquired knowledge in an area that is likely helpful in performing a job. Other certificates reflect 31 in areas so new, or quickly changing, that a demonstrated specialty can put a job applicant in front of the pack: homeland security, sports industry management. Some are purely 32 (African American studies), and some are training-specific (clinical research administration). If you can think of a specialty or job skill you want, there is probably a certificate, and a school-on-ground or online—that will qualify you in the subject. But it is a buyer-beware marketplace, education experts say. A certificate can run into the thousands of dollars (American University's 15-credit online digital media skills certificate costs $12000), so job 33 and schools should be researched before 34 on. A. academic B. boost C. distinguish D. eligible E. identify F. insisting G. investment H. involvement I. limitations J. prospects K. signing L. specialized M. specified N. strengths O. technical

单选题 中国长城(the Great wall)的历史可追溯到公元前5世纪。它建成于公元前5世纪到16世纪之间，目的是保护中国的北部边界。长城是中国历史的一个重要组成部分，对当今中国有着深远的影响。可以说，从某种意义上来看，长城就是历史。大多数人倾向于认为，长城是战争的产物(实际上是防御的产物)，因而其作用理应是和战争紧密相连。但是，情况并非如此。长城存在的大部分时期是和平时期而不是战争年代。大多数时候，长城与文化、外交政策和经济相关。

单选题Monkeys and chimpanzees, although they are weaker and less fierce than many other animals, possess brains which are 55 far along the evolutionary road as any creature other than man. Birds can perform marvels of aerobatics, they can catch insects on the wing with unparalleled skill, they can navigate in a remarkable manner half round the world and back—but they cannot think and reason. In technical terms it can be said that they are lacking in insight. The abilities which they do possess are built-in instincts derived from their genetic inheritance. Monkeys, on the other hand, can reason. They can easily remember a lighted door indicating the presence of food. They can remember what kind of food they are looking for. A monkey set the problem of reaching a banana, say, hung high up in its cage, can work out a system for getting it even if it involves piling up boxes to stand on and then knocking down the banana with a stick. A charming story is told about the psychologist Wolfgang Kobler, who had provided various boxes and other apparatuses by which he proposed to test a chimpanzee"s ability to think out a method of reaching a fruit hung nine feet in the air. The animal looked about it and sized up the problem. Then it took Kobler by the hand, led him to a position immediately under the banana, jumped up on to his shoulder and reached it down from there. But evolution, although it has brought monkeys to a remarkable degree of cleverness, has stopped short at a crucial ability, the possession of which places man at a clearly superior level. Their minds cannot cope with abstract ideas. For example, an ape can be taught to fill a can with water from a barrel and take the can of water to put out a fire so that it can reach into a box and get food. But if the whole set-up is arranged on a raft the animal will continue to draw its water only from the barrel. It can not grasp that any water, taken more, conveniently, say, from the pond on which the raft is floating, will pot out the fire just as well. The abstract idea that water puts out fire is beyond it.
