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 provid 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.



选B,有牛牛能解释一下吗？

谢谢！；）

题目：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 provid effective treatment for those infections.

文中已说明：Antibiotics have no effect on the virus。A跟文是矛盾的。不选。

(B) Children infected with the virus are particularly susceptible to bacterial that infect the middle age.

B只能说helps to explain. 小孩既被病毒感染，又被细菌感染。所以Antibiotics杀了细菌使中耳CLEAR UP了。

(C) Many children who develop middle ear infections are not infected with the virus.
C对解释Antibiotics治疗被VIRUS感染的耳朵没有任何帮助。

(D) Most viral infections are more difficult to treat than are most bacterial infections.
D陈述上没有问题，但不能帮助解释为什么Antibiotics治疗被VIRUS感染的耳朵。

(E) Among children not infected with the virus, fewer than 30 percent develop middle ear infections.
E这个数字得出来的挺可笑的。并且对“Antibiotics治疗被VIRUS感染的耳朵”没有任何帮助。

typing error 吧，如果把B选项中的middle age改成 middle ear是不是就容易懂了？
