Part I Reading Comprehension （30 %）
Directions: There are three passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and blacken the corresponding letter on the Answer Sheet. Passage One
―I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,‖ says microbiologist Robert Weinberg，an expert on cancer. ―But,‖ he cautions, ―some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available.‖
This year，50 percent of the 910 000 people who suffer from cancer will survive at least five years. In the year 2000, the National Cancer Institute estimates, that figure will be 75 percent.76) For some skin cancers，the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging – 13 percent for lung cancer，and 2 percent for cancer of the pancreas(胰腺)．
With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes(基因)，are inactive in normal cells. Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknown．If several oncogenes are driven into action，the cell，unable to turn them off，becomes cancerous．
77) The exact mechanisms involved are still mysterious, but the likelihood that 第 1 页 共 30 页
many cancers are initiated at the level of genes suggests that we will never prevent all cancers. ―Changes are a normal part of the evolutionary process,‖ say oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, ―We can’t prepare a medicine against cosmic rays.‖ The prospects for cure, though still distant, are brighter.
―First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells which are always responsible for a least part of the trouble. If we can understand how cancer works, we counteract its actions.‖
1. The purpose of taking the example of Pasteur is to __D___. A. predict that the secret of cancer will be exposed in a decade B. illustrate that the prospects for curing cancer are bright C. prove that cancer will be cured in ten years
D. indicate that there is still a long way to go before cancer can be conquered 2. By the year 2000, it is possible that___D___. A. there will be a remedy to cure all the cancer.
B. 90 percent of the skin-cancer patients today will still be living
C. the survival statistics will be fairly even among patients with various cancers D. there won’t be a drastic increase of survival rate of all cancer patients 3. Oncogenes are cancer-causing genes___B___. A. that are always in operation in a healthy person
B. which remain unharmful so long as they are not activated C. that can be driven out of normal cells D. which normal cells can’t turn off
4. The word ―dormant‖ in the third paragraph most probably is replaced by__D___. A. sleepy B. potencial C. dead D. inactive 5. It can be included that__D__.
A. once someone understands the causes of cancer, the cure will rapid follow B. it is known that how to activate a dormant oncogene C. the prospect for curing cancer is not bright at all.
D. we can’t counteract cancer’s action unless we know how cancer works Passage Two
Kelley McKee of Steelton, Pennsylvania, never had any intentions of taking Distance Education courses. She had already obtained a certificate at a business school. She was married, had children and worked as a legal assistant. But her life changed forever when she broke her neck and became paralyzed. She was just 27 years old.
A certificate offers a shorter course of study than a degree. Certificates can serve as steppingstones to a degree. 78)A certificate typically requires at least 12 semester 第 2 页 共 30 页
credits of coursework. With program faculty approval, credits completed in a certificate program may be used in a degree program. Distance education
Distance Education is instructional delivery that does not constrain the student to be physically present in the same location as the instructor. Historically, distance education meant correspondence study. Today, audio, video, and computer technologies are more common delivery modes.
Studying 4 years at a college or university, known as \education, will generally lead to the Bachelor's Degree. Master's degree
This is the degree a student gets after he studies beyond the 4 years of college. The MBA. or Master of Business Administration, is an extremely popular degree that usually takes two years. Some Master's programs, such as journalism, only take one year. In such fields as history and philosophy, these degrees are considered stepping-stones toward a doctorate (Ph.D.).
Financial aid, disability service and vocational rehabilitation
In the USA there are a number of state and federal laws that protect the equal rights of handicapped and disabled persons to education, employment, housing, etc. For example, classrooms and offices must be accessible to people with wheelchairs or crutches, so most of them have special ramps and elevators for this purpose.
Over time, Kelley has learned to move her fingers enough to use a computer and to get around daily with the help of a wheelchair. Although that progress is not enough to allow her to continue her previous career, other opportunities have opened up for her.
Kelley said, \changed my outlook on life, and I immediately looked to education since I had no degree.\not allow her to balance her education with a growing family. Then, Kelley found Penn State Distance Education.
Distance Education is hard work, but my children make it all worthwhile. Even if for some reason I can't work after obtaining my degree, I will be an educated person, setting a good example for my children and having gained the knowledge that can help them in their future efforts. Distance Education has changed my life from tragedy to triumph,\said. Distance Education affords me an opportunity to pursue my own goals and personal work. My education is separate from my \issues regarding my disability or my family life and caring for my children.\
Commenting on McKee's experience, Gary E. Miller, vice president for Distance Education and director of the World Campus, noted, \is a wonderful reminder about the impact of Distance Education on the lives of our students who cannot meet their needs through traditional on-campus programs.\

Jane Ireland, academic advisor for Distance Education and the World Campus, added: %us of the mission we have in Distance Education--to bring a quality education and experience to students regardless of their geographic vocation or life circumstances. Kelley is a wonderful example for us of the great effect we have on the lives of a great many students who truly need access to education.\
Kelley is a successful student, carrying credits each semester. She plans to complete her bachelor's degree in letters, arts, and sciences, then continue on to obtain an online master's degree.
After graduation, McKee hopes to work with injured or disabled individuals, possibly in counseling in a rehabilitation setting. Jane Ireland has no doubt Kelley will achieve her goals.
79) Kelley is thankful to her outstanding instructors and a number of student support services, including financial aid, disability services and vocational rehabilitation. Many of these faculty and staff, however, say that it is Kelley McKee who has been outstanding.
Susan Waitkus, instructor in English at Penn State's DuBois Campus, stated, Kelley inspires not only other students, but also faculty fortunate enough to know her. She reminds us how privileged we are to teach.\
