M: Well, as stated on my resume, I worked for five years at Hi Tech Computers.
W: OK, Hi Tech. And what do you know about computer networks and operating systems including DOS, Windows, Macintosh OS, and UNIX？
M: Umm...well...I did come in contact with computers every night at my last job.
W: Hum...And how about web site authoring skills？ We are looking for someone to create and manage our company's web site which would include the development, configuration, and use of DOS, Windows, Macintosh OS, and CGI scripts.
M: Umm...uh, web page, web page. Huh...I don't think I've read that book, and Fm afraid I've never used those CGI things.
W: Huh？! And what about experience with Java or JavaScript？
M: Well...I think I've tried Java at a foreign coffee shop one time, if that's what you mean.
W: OK, Mr. Taylor, I think I have all the information I need!
M: Oh, and I really like computer games. I play them every day.

In recent years a new farming revolution has begun, one that involves the 【B1】______ of life at a fundamental level--the gene. The study of genetics has 【B2】______ a new industry called biotechnology. As the name suggests, It 【B3】______ biology and modern technology through such techniques as genetic engineering. Some of the new biotech companies specialize in agriculture and are working feverishly to 【B4】______ seeds that give a high yield, that 【B5】______ diseases, drought and frost, and that reduce the need for 【B6】______ chemicals. If such goals could be achieved, it would be most 【B7】______ . But some have raised concerns about genetically engineered crops.
In nature, genetic diversity is created within certain 【B8】______ . A rose can be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering, 【B9】______ usually involves taking genes from one species and inserting them into another 【B10】______ to transfer a desired characteristic. This could mean, for example, selecting a gene which leads to the production of a chemical with anti-freeze 【B11】______ from an artic fish, and inserting it into a potato or strawberry to make it frost-resistant. 【B12】______ , then, biotechnology allows humans to 【B13】______ the genetic wails that separate species.
Like the green revolution, 【B14】______ some call the gene revolution contributes to the problem of genetic uniformity--some say even more so 【B15】______ geneticists can employ techniques such as cloning and 【B16】______ culture (培养), processes that produce perfectly 【B17】______ copies. Concerns about the erosion of biodiversity, therefore, remain. Genetically altered plants, however, raise new 【B18】______ , such as the effects that they may have on us and the environment. "We are flying blindly into a new 【B19】______ of agricultural biotechnology with high hopes, few constraints, and little idea of the potential 【B20】______ " said science writer Jeremy Rifkin.
