In a small laboratory at the Medical University of South Carolina, Dr. Vladimir Mironov has been working for a decade to grow meat.
    A developmental biologist and tissue engineer, Dr. Mironov is one of only a few scientists worldwide involved in bioengineering “cultured” meat.
    It’s a product he believes could help solve future global food crises resulting from shrinking amounts of land available for growing meat the old-fashioned way.
    Growth of cultured meat is also under way in the Netherlands, Mironov told Reuters in an interview, but in the United States, it is science in search of funding and demand.
    The new National Institute of Food and Agriculture won’t fund it, the National Institutes of Health won’t fund it, and NASA funded it only briefly, Mironov said.
     “It’s classic disruptive technology,” Mironov said. “Bringing any new technology on the market, on average, costs $1 billion. We don’t even have $1 million.”
    Director of the Advanced Tissue Biofabrication Center in the Department of Regenerative Medicine and Cell Biology at the medical university, Mironov now primarily conducts research on tissue engineering, or growing, of human organs.
     “There’s an unpleasant factor when people find out meat is grown in a lab. They don’t like to associate technology with food,” said Nicholas Genovese, a visiting scholar in cancer cell biology.
     “But there’re a lot of products that we eat today that are considered natural that are produced in a similar manner,” Genovese said.
Questions 19 to 21 are based on the passage you have just heard.
19. What does Dr. Mironov think of bioengineering cultured meat?
20. What does Dr. Mironov say about the funding for their research?
21. What does Nicholas Genovese say about a lot of products we eat today?

选项 A、They are less healthy than we expected.
B、They are not as natural as we believed.
C、They are not as expensive as before.
D、They are more nutritious and delicious.

答案 B

解析 D)中的nutritious,delicious提示,They可能指某类食物;结合healthy, natural和expensive推测,本题可能考查这种食物的具体特点。短文结尾Genovese说,很多我们目前正在食用并被认为是天然的食物都produced in a similar manner(是以类似的方法生产出来的),“类似的方法”指的是前面提到的grown in a lab(在实验室中生产出来),由此可知很多我们正在食用的食物并不像想的那样是天然的,故答案为B)。弄清in a similar manner指的是什么方法是解题的关键。
