But can

16、GM technology solve world hunger problems? Even if it would, is it the best solution? Despite what it promises, GM technology actually has not increased the production potential of any corp. In fact, studies show that the most widely grown GM crop. GM soybeans, has suffered reduced productivity. For

17、 instance, a report than analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production.Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good pr

18、ofits by saving money on pesticides（殺蟲劑）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christi

19、son, President of the US National Farm Coalition.At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indee

20、d deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that GM crops have littl

21、e to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.57. The author develops the second paragraph mainly _.A. by classification B. by comparison C. by example D. by process 58. What does th

22、e underlined word “boost” in the third paragraph probably mean?A. Control. B. Evaluate C. Obtain. D. Increase. 59. GM companies promise farmers that they will benefit from _. A. practicing “green” farming B. use of less chemicalsC. fair distribution of their crops D. using more crops for fuel 60. Wh

23、ich of the following best describes the attitude of the author towards GM technology?A. Optimistic B. Defensive C. Disapproving D. CasualB Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can ari

24、se when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.“To provide enough power, we need certain methods with high energy density(密度)”, said Jae Kwon,

25、assistant professor of electrical and computer engineering at MU. “The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries.”Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, i

26、ntended to power various micro / nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.“People hear the word nuclear and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety o

27、f devices, such as pace-makers, space satellites and underwater systems.”His new idea is not only in the batterys size, but also in its semiconductor(半導(dǎo)體). Kwons battery uses a liquid semiconductor rather than a solid semiconductor.“The key part of using a radioactive battery is that when you harves

28、t the energy, part of the radiation energy can damage the lattice structure(晶體結(jié)構(gòu)) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor

29、, Kwon is working to build and test the battery. In the future, they hope to increase the batterys power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.71. Which of the following is true of Jae Kwon?A. He teaches chemis
