608. In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding to proteins on its surface. Mice infected with the herpesvirus generally develop keratitis, a degenerative disease affecting part of the eye. Since proteins on the surface of cells in this part of the eye closely resemble those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies to the herpesvirus.
Which of the following, if true, most helps to support the scientists’ reasoning?
A. Other types of virus have surface proteins that closely resemble proteins found in various organs of mice.
B. Mice that are infected with the herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis.
C. Mice infected with a new strain of the herpesvirus that has different surface proteins did not develop keratitis.
D. Mice that have never been infected with the herpesvirus can sometimes develop keratitis.
E. There are mice that are unable to form antibodies in response to herpes infections, and these mice contract herpes at roughly the same rate as other mice.
题目大意
为了应对病毒感染，老鼠的免疫系统通常会产生抗体，通过与病毒表面的蛋白质接触来杀死病毒。感染了h病毒的老鼠通常会得角膜炎，一种影响眼睛的退化性疾病。因为这时眼球细胞表面的蛋白质非常类似于h病毒表面的，科学家假设这种角膜炎是由h病毒抗体引起的。
解题思路
问题问下面选项如果是真的，哪个最有助于支持科学家的说法。也就是要说明角膜炎就是h病毒的抗体引发的。
A：其他种类的病毒表面的蛋白质和老鼠不同器官的蛋白质很相似。错，其他病毒与原文无关。
B：被h感染但没有得角膜炎的老鼠会产生和得角膜炎的老鼠一样多的抗体。错，得不得病都有一样的抗体，说明这个抗体和疾病没关系。
C：感染了有不同表面蛋白质的新种类h病毒的老鼠没有得角膜炎。正确，排除了它因，角膜炎可能是由其他东西导致的，这里排除了其他蛋白质引发的抗体导致疾病的可能，原文的那种抗体引发疾病的说法就更有可能成立。
D：从来没有感染过h病毒的老鼠也会的角膜炎。错，这就说明和h病毒的抗体没关系了。
E：有的老鼠不能产生抗体去应对h病毒的感染，这些老鼠和其他老鼠有大致相同的几率去感染上h病毒。错，只说有相同的可能感染，没有说会不会得病，与原文无关。
答案：C
