试题详情

题目:

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 a 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 herpesvirus.
 
Which of the following, if true, gives the greatest additional support to the scientists' hypothesis?

选项:

A、Other types of virus have surface proteins that closely resemble proteins found in various organs of mice.
B、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.
C、Mice that are infected with a herpesvirus but do not develop keratitis produce as many antibodies as infected mice that do develop keratitis.
D、There are mice that are unable to form antibodies in response to herpes infections, and these mice survive these infections without ever developing keratitis.
E、Mice that have never been infected with a herpesvirus can sometimes develop keratitis.

答案:

D

提问:

完全不理解这道题,OG19的答案是C,答疑器上没有C这个答案。我选了C,但是想不明白为什么,是排除了其他因素吗?

提问:

请问张慧雯老师,P:感染H的小老鼠会出现k,而h表面的蛋白质与K的眼睛细胞表面蛋白质相似 C:k是由于H引起的,这题CD如何区别呢?本题和og上面类似的题目区别在哪?

提问:

我读完题,按照老英您上次交的方法,用一句话提炼文章,就是k这个病是由于h的抗体造成的。然后要加强这个hypothesis。 A说proteins去了,无关 B跟contract h的速度,无关 C说的啥也没太看懂,但感觉有点关系,先留着 D也是没太看懂,但感觉有点关系,留着 E句子短还能看下去,说没有感染h病毒的有时候也会得k病,好像有点关系 于是在CDE中间选,心想跟没排一样==! 然后就无比烦躁,于是就瞎选了一个。。 感觉这种题有这么多不认识的单词,又是h病毒吧,又是k病吧,又是抗体吧。。完全晕菜了!选项又特绕,简直读不下去的感觉,心里好烦躁。。 求老师拯救>_<

提问:

这道题问的是支持hypothesis 所以我觉得重点应该看最后一句话,虽然我之前的也是读了的,但是没有太明白,大概一个老鼠产生一种抗体可以摧毁病毒通过和蛋白结合在一起。老鼠感染了h会产生k,k会影响眼睛。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 herpesvirus.然后我就晕了, 这道题可以简化一下么?考场上应该怎么办?

提问:

原文实在读得太晕了,就读出来大概是老鼠感染病毒免疫系统会产生抗体,通过联合蛋白质什么的,反正就是说免疫系统的反应,然后又说老鼠感染眼病会产生k这个物质,发现眼睛细胞上的蛋白质和h表面的相似,所以假设K是由h抗体引起的,让支持,因为完全没明白什么意思觉得肯定和k相关留下CDE,觉得E好像方向错了,CD之间无法取舍就选了C,请老师讲一下
