98【抗生素】

by tiantian5 (700)

所有的抗生素在使用长时间后都慢慢没效果了因为病毒能抵抗它了，然后举了特例说一种新药开始在人类中使用，这个要已经长时间给牲口用了,为了治疗P这个病毒，所以呢科学家就说这个新药在人身上肯定也没用了。问assumption。我选的是P直接或间接会从牲口传染到人。

60. Since the routine use of antibiotics can give rise to resistant bacteria capable of surviving

antibiotic environments, the presence of resistant bacteria in people could be due to the

human use of prescription antibiotics. Some scientists, however, believe that most resistant

bacteria in people derive from human consumption of bacterially infected meat.

Which of the following statements, if true, would most significantly strengthen the

hypothesis of the scientists?

(A) Antibiotics are routinely included in livestock feed so that livestock producers can

increase the rate of growth of their animals.

(B) Most people who develop food poisoning from bacterially infected meat are treated with

prescription antibiotics.

(C) The incidence of resistant bacteria in people has tended to be much higher in urban

areas than in rural areas where meat is of comparable quality.

(D) People who have never taken prescription antibiotics are those least likely to develop

resistant bacteria.

(E) Livestock producers claim that resistant bacteria in animals cannot be transmitted to

people through infected meat.

60.

If livestock are routinely fed antibiotics, as choice A states, meat from livestock is likely to

contain the resistant bacteria, since any routine of antibiotics can result in resistant bacteria.

Thus, choice A is the best answer.

How cases of food poisoning are treated (choice B) fails to indicate whether the infecting

bacteria are resistant bacteria. Choice C suggests that meat consumption is not the primary

culprit for the high incidence of resistant bacteria. Choice D tends to support the competing

hypothesis that prescription antibiotics are responsible. Choice E asserts that livestock

farmers claim that the hypothesis is false, but it provides no basis for evaluating the truth of the

claim.
