问题
The body of anyone infected by virus X will, after a week, produce antibodies to fight the virus; the antibodies will increase in number for the next year or so. There is now a test that reliably indicates how many antibodies are present in a person’s body. If positive, this test can be used during the first year of infection to estimate to within a month how long that person has had the virus. Which one of the following conclusions is best supported by the statements above?
选项
A、Antibodies increase in number only until they have defeated the virus.
B、Without the test for antibodies, there is no way of establishing whether a person has virus X.
C、Antibodies are produced only for viral infections that cannot be fought by any other body defenses.
D、If a person remains infected by virus X indefinitely, there is no limit to the number of antibodies that can be present in the person’s body.
E、Anyone infected by virus X will for a time fail to exhibit infection if tested by the antibody test.
答案
E
解析
由本题的第一句话可知,任何一个感染了X病毒的人,在一周后身体内才会产生抵抗这种病毒的抗体。因此基于对抗体测试的方法将至少在一个人感染上X病毒后的一周内检查不出他已感染了这种病毒,所以(E)是正确的;从段落中可知抗体的数量只是在感染后的第一年内会增加,因此(A)和(D)都是错误的;(H)过于绝对化,因为抗体测试只是确定一个人是否感染了X病毒的一种方法,而不是仅有的方法;(C)引入了新的比较,因此也是不对的。
