2、stions 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 well know in vast detail how cancer cells ar

3、ise,” 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

4、available.” 76）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. For some skin cancers，the five-year survival rate is as high as 90 percent. But other survival

5、 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.

Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknownIf several oncogenes are driven into action，the cell，unable to turn them off，becomes cancerous77) The exact mechanisms involved are still mysteriou

7、s, but the likelihood that 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 cant

8、 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 th

14、ol. 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. 78）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

15、. Although that progress is not enough to allow her to continue her previous career, other opportunities have opened up for her. Kelley said, The accident changed my outlook on life, and I immediately looked to education since I had no degree. Most traditional programs did not allow her to balance h

16、er 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 cant work after obtaining my degree, I will be an educated person, setting a good example for my children and havin

Miller, vice president for Distance Education and director of the World Campus, noted, Kelleys story is a wonderful reminder about the impact of Distance Education on the lives of our students who cannot meet their needs

19、through traditional on-campus programs.

20、ces. 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 bachelors degree in letters, arts, and sciences, then continue on

21、to obtain an online masters 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 s

22、upport 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.

28、e, relatively easy to access, and provides virtually unlimited information. An excellent resource to gain knowledge, the Web is leading the information revolution. It has made a huge difference in the world, and will continue to do so. When you need current information and you need it now, there is

The advent of the Web as a research tool has greatly expanded the availability of information while reducing the amount

30、of time needed on each task. The majority of my time on the Web involves looking up technical computer information, which I use for teaching Microsoft applications classes and providing technical advice at work. Outside of work, I really like following all aspects of the financial world, and the Web

The amount of information on the Web is stagg

32、ering, so it is important to remember what it is you are searching for and not get sidetracked. The Web is a wonderful resource when you can substantiate that the information provided is accurate and true. Like any other resource, the Web has good and not so good information to share. Depending on what you are looking for, you have to judge for yourself how relevant the material is for you. It is important
