2、s following the outline given below in Chinese: 1. 从 Professor Smith的授课中所获得的收获 2表达对其的感激之情 A Send-off Speech 二、 Part II Reading Comprehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the

3、 passage.

4、re of genomic medicine Just mentioning “stem-cell research“ or “genomic medicine“ can open a floodgate of beliefs, concerns and, misinformation. Opinions are varied, mixed with fact and fiction, but one thing is clear: Open dialogue among researchers, teachers and the general public must continue as

5、 we struggle to define the relationship between our societal values and lifesciences research. When the University of Washington .and the National Human Genome Research Institute hosted a community genetics forum last spring, questions abounded from the standing-room-only crowd about the implication

6、s of genetic research. When is information about genetic health risks most helpful? Should genetic testing results be part of medical records and how would the results be used potentially by insurance companies? How can genetic testing benefit the criminal-justice system, such as establishings guilt

7、 or innocence using DNA testing, The Human Genome Project will lead to amazing advances in medical science that will result in earlier diagnosis, more-targeted treatment, and a dramatic improvement in our ability to prevent terrible diseases. Genomic medicine will mean more personalized medicine tai

8、lored to the individual. But these advances also carry inherent risks. The obvious benefits of “personalized medicine“ use of genetic tests to guide preventive care and better drug prescribing are counterbalanced by the possibility that such tests could lead to discrimination by insurers or employer

9、s. And, since genetic risk is often only one of the contributing factors to disease, overemphasis on personalized medicine could burden our health-care system with genetic tests of little or no benefit. For example, smoking, diet and exercise play major roles in the risk of diabetes and heart diseas

10、e. Identification of a genetic risk for these diseases can provide specific information for more-effective preventive care, but should not detract from pursuit of a healthy lifestyle. The greatest health benefits of genomic research likely will come from insights into the basic biology of health and

11、 disease. This will ultimately lead to improved prevention and treatment often without any need for genetic testing for many diseases. The outcome from this research can be “precision medcine“ a morecost-effective approach to providing high-quality care. Thus, genomic medicine has the potential to i

12、mprove the value of health care. An example of the potential of genomic medicine to improve quality and reduce cost is the work of UW researchers Mark Rieder, Allan Rettie and Debbie Nickerson. They recently reported the discovery of a genetic method for accurately determining the proper dosage of a

13、 common blood-thinning drug, warfarin, which often produces adverse side effects because of its highly variable activity in patients. Millions of people worldwide take worldwide to prevent stroke and blood clots, yet require expensive, constant testing from their physician to ensure proper dosage. T

14、hese scientists findings illustrate how the powerful DNA analysis tools of the Human Genome Project are leading to a new era of tailoring drugs and therapies to an individuals genome. Genomic medicine can lead to more-precise, personalized and cost- effective health care. Medical advances always inv

15、olve risk of harm, and genomic medicine is no exception. While technical issues require scientific research, we believe the challenges posed by genetic testing are far too critical to be left to the deliberation of scientists alone. All members of society should have the opportunity to engage in col

16、laborative discussion about the benefits and harms of genetic testing. Informed public discussion is vital to continue advances that hold so much promise for improving the value of health care. Both educational resources and major organizational efforts will be needed to create opportunities for ope

17、n discussion. But the most important resources are peoples time and their willingness to invest it in these discussions. Researchers, teachers and the media have an obligation to create opportunities for sharing accurate, well-balanced information about potential uses of genomic technology. 2 The Un

Because music is so important in the lives of many Africans and because so much music is performed in Africa, we are

48、 inclined to think that all Africans are musicians. The impression is strengthened when we look at ourselves and find that we have become largely a society of musical spectators. Music is important to us, but most of us can be considered consumers rather than producers of music. We have records, tel

49、evisions, concerts, and radios to fulfill many of our musical needs. In most situations where music is performed in our culture it is not difficult to distinguish the audience from the performers, but such is often not the case in Africa. Alban Ayipaga, a Kasena semiprofessional (半职业 性的 ) musician from northern Ghana, says that when his flute (长笛 ) and drum en
