狒狒逻辑117题 疑问！！！

117. A certain viral infection is widespread among children, and about 30 percent of children infected with the virus develop middle ear infections. Antibiotics, although effective in treating bacterial infections, have no effect on the virus. Yet when middle ear infections in children infected with the virus are treated with antibiotics, the ear often clear up.

Which one of the following most helps to explain the success of the treatments with antibiotics?

A.    Although some types of antibiotics fail to clear up certain infections, other types of antibiotics might provide effective treatment for those infections.
B.    Children infected with the virus are particularly susceptible to bacterial that infect the middle age.
C.    Many children who develop middle ear infections are not infected with the virus.
D.    Most viral infections are more difficult to treat than are most bacterial infections.
E.    Among children not infected with the virus, fewer than 30 percent develop middle ear infections.

答案选B  怎么跳出来个Middle age？！完全不明白

这道题我觉得应当选C吧
大家想想，题目说有30%被virus感染的小孩会得中耳炎，但并没有说得中耳炎的小孩都是因为此virus感染。C正好阐明了这种可能，就是如果得中耳炎的小孩大部分是因为bacteria，那么Antibiotic就会治好他们啦。

就是实在理解不了的时候也别死磕一道题,理解一下解题思路就行了.别钻牛角尖.

我还是很糊涂的说

viral infection这个病，30%的患者因virus感染（antibiotics治不好）《暗示，70%的患者是bacterial感染，没有virus，antibiotic可治好》
现在，用antibiotics治，小孩的病好了


求解释

B.    Children infected with the virus are particularly susceptible to bacterial that infect the middle age.
指出 小孩得的病 是由 bacterial 引起的，antibiotics可治好

这里其实给人感觉还是很奇怪，children infected with virus。。virus可能是指viral infection这个病，而不是后面说不能治好的那个virus
middle age  是修饰bacteria， 意思只能忽略了，反正是一种类型的bacteria，只要是bacteria，就能治好

我觉得没得选的话，b不对也对，选出来就得。这个题目的逻辑链搞清楚了对其余的逻辑题没一点实际性的帮助，知道怎么选，下次还能用就ok

我觉得可以把答案比较一下
文中大概说了这么个意思：
1，30%的被某病毒感染的小孩得了中耳炎
2，病毒没什么东西能克制他
3、但是小孩被抗生素治好了

a，infections, other types of antibiotics 。。。。。别的抗生素，肯定无关
b，得病的小孩怎么怎么样，有点关系
c，小孩不是因为病毒而得病的，我们说的是因为病毒而得病的小孩，对象不对
d，病毒和细菌比，好像没什么关系
e， Among children not infected with the virus，没得《病毒》病的小孩？？？无关，原因同c
所以我觉得剩下的就是b了
