Day 59
1. 自带杀虫天赋的种子之一
Scientists have made genetic modifications to cotton to increase its resistance to insect pests. According to farmers' report, the amount of insecticide needed per acre to control insect pests was only slightly lower for those who tried the modified seed than for those who did not. Therefore, since the modified seed costs more than ordinary seed without producing yields of higher market value, switching to the modified seed would be unlikely to benefit most cotton farmers economically.科学家对棉花进行进行基因改在使棉花防虫,根据农民,使用转基因种子,为了控制害虫每公亩需要的杀虫剂只比不用转基因种子少很小一点。因此,转基因种子比普通种子成本更高且没有更高的产出市场价值,转向使用转基因种子对棉花农民的经济上没有好处。
Which of the following would it be most useful to know in order to evaluate the argument?
A.Whether farmers who tried the modified cotton seed had ever tried growing other crops from genetically modified seed 跟其他农作物无关,只是在讲棉花
B.Whether the insecticides typically used on ordinary cotton tend to be more expensive than insecticides typically used on other crops 跟其他农作物无关
C.Whether for most farmers who grow cotton it is their primary crop 棉花是不是最主要农作物,无关
D.Whether the farmers who have tried the modified seed planted as many acres of cotton, on average, as farmers using the ordinary seed did 转基因种子和普通种子的公亩数量,无关
E.Whether most of the farmers who tried the modified seed did so because they had previously had to use exceptionally large quantities of insecticide 如果是,之前用了大量杀虫剂,那减少就说明经济上有好处,如果不是,那就说明经济上没好处,我选E
2. 自带杀虫天赋的种子之二
Plant scientists have been able to genetically engineer vegetable seeds to produce crops that are highly resistant to insect damage. Although these seeds currently cost more than conventional seeds, their cost is likely to decline. Moreover, farmers planting them can use far less pesticide, and most consumers prefer vegetables grown with less pesticide, therefore, for crops for which these seeds can be developed, their use is likely to become the norm.
第一句话一样。转基因种子成本高,但是成本即将下降,农民认为可以少使用杀虫剂,消费者喜欢少农药的蔬菜,因为转基因种子使用将变成日常
which of the following would be most useful to know in evaluating the argument above?
A.Whether plant scientists have developed insect-resistant seeds for every crop that is currently grown commercially 不需要对所有农作物都有效
B.Whether farmers typically use agricultural pesticides in larger amounts than is necessary to prevent crop damage. 无关
C.Whether plants grown from the new genetically engineered seeds can be kept completely free of insect damage. 不需要完全防虫,防大部分就有效了
D.Whether seeds genetically engineered to produce insect-resistant crops generate significantly lower per acre crop yields than do currently used seeds. 转基因农作物产量低于普通的,那就会影响农民选择转基因种子,正确
E.Whether most varieties of crops currently grown commercially have greater natural resistance to insect damage than did similar varieties in the past. 无关
3. 火星人入侵地球啦!
"The panic touched off by Orson Welles’s 1938 radio broadcast of the science-fiction classic War of the Worlds has often been the ascribed to the lingering anxieties of the Depression era and apprehension about the a second world war; political and economic unease supposedly made people psychologically prepared to believe that Earth had been invaded by Martians.
由QW广播的科幻小水XX引起的恐慌经常被描述为对于第二次世界大战的消极情绪,政府和经济应该使人们心理上准备好相信火星人要入侵地球了。
Which of the following, if true, would most seriously weaken the attempt above to explain the panic of 1938?
(A) Film adaptations of War of the Worlds are generally regarded as less realistic than Welles’s radio version. 无关
(B) Rebroadcasts of Welles's War of the Worlds during times of peace and economic optimism have on occasion resulted in similar panics. 在和平时期也会造成同样的恐慌,无关
(C) The 1898 publication of the novel on which the radiobroadcast of War of the Worlds was based resulted in no public disturbances. 小说建立在无公众影响,无关
(D) Even after the invasion depicted in the 1938 radio broadcast had been widely publicized as fictitious, some people maintained that they had seen the Martian invaders. 有些人看到了火星人,应该算是加强,而且一些人的观念无关影响结论
(E) Some people who had not listened to the 1938 radio broadcast were nonetheless caught up in the resulting panic." 没听广播的人也产生了恐慌,我选E
