标题: 陈向东逻辑-解释-抗生素与免疫系统 [打印本页] 作者: evelyn205205 时间: 2011-7-9 20:59 标题: 陈向东逻辑-解释-抗生素与免疫系统 Studies have shown that people who rarely take antibiotics, which are antibacterial drugs, have stronger immune systems than do people who take antibiotics frequently. Yet there is no evidence that taking antibiotics weakens the immune system.
Which of the following, if true, best reconciles the apparent discrepancy in the information above?
(A) People who have strong immune systems seldom get the kinds of infections for which people normally take antibiotics. (B) People who have strong immune systems are seldom aware that their immune systems are unusually strong. (C) People who have weak immune systems have great difficulty recovering from bacterial infections if they do not take antibiotics. (D) Some people take antibiotics even though the antibiotics cause a variety of side effects. (E) Some people take antibiotics frequently because their doctors prescribe antibiotics for viral infections as well as for bacterial infections.
