A mosquito bite can transmit to a person the parasite that causes malaria, and the use of mosquito nets over children's beds can significantly reduce the incidence of malarial infection for children in areas where malaria is common. Yet public health officials are reluctant to recommend the use of mosquito nets over children's beds in such areas.

Which of the following, if true, would provide the strongest grounds for the public health officials' reluctance?

GWD-9-Q12:





A mosquito bite can transmit to a person the parasite that causes malaria, and the use of mosquito nets over children’s beds can significantly reduce the incidence of malarial infection for children in areas where malaria is common. Yet public health officials are reluctant to recommend the use of mosquito nets over children’s beds in such areas.





Which of the following, if true, would provide the strongest grounds for the public health officials’ reluctance?











A.Early exposure to malaria increases the body’s resistance to it and results in a lesser likelihood of severe life-threatening episodes of malaria.





B.Mosquito bites can transmit to people diseases other than malaria.





C.Mosquito nets provide protection from some insect pests other than mosquitoes.





D.Although there are vaccines available for many childhood diseases, no vaccine has been developed that is effective against malaria.





E.The pesticides that are most effective against mosquitoes in regions where malaria is common have significant detrimental effects on human health.

答案是A。可我的疑惑在C选项,我觉得更直接。因为文中说蚊帐能减少疟疾的感染,一般会认为潜在的逻辑是能阻挡蚊子的叮咬,可是原文并没这么说,所以我觉得我们只能由原文得出这样两条逻辑链——1. 蚊子的叮咬会传染疟疾; 2. 蚊帐能减少疟疾的感染率。然后,原文问为什么官员不愿意推荐用蚊帐。我觉得最直接的理由应该是C,因为蚊帐不能阻止蚊子(虽然听上去很没道理,可是原文确实并没有给我们这个逻辑链)。

而A虽然也可以解释官员为什么不推荐用蚊帐,可毕竟是谈及了原文未谈论到的范围——疟疾能引发身体产生免疫。我觉得这个解释也有点荒唐,万一小孩因为得疟疾而死亡呢?

所以,总的来说,我认为C更直接。请大家指教。

况且你怎么知道不能阻挡蚊子?即因为文章阻挡了其他的虫?

题目是问为什么官员不愿意用蚊帐啊,而C说:蚊帐能防止除蚊子外的其他有害昆虫(other than mosquitos),这不就是说不能防止蚊子吗?

还请指教

这道题我最开始也选择了C,后来发现把意思理解错了。

C.Mosquito nets provide protection from some insect pests other than mosquitoes.

表示蚊帐除了可以防蚊,还可防其他一些害虫。 other than表示除了

我刚查了下金山词霸(不好意思,可能不够权威,但我手上没有更权威的辞典),对other than的解释如下:

other than
[with negative or in questions]apart from; except
除了
he claims not to own anything other than his home.
他声称除了家他一无所有。
■differently or different from; otherwise than
不同于;非
there is no suggestion that we are to take this other than literally.
并没有要我们不按字面去理解的意思。

按这个说法,other than应该是except,而不是besides。还请指教。

题目说: the use of mosquito nets over children’s beds can significantly reduce the incidence of malarial infection for children in areas where malaria is common.就已经说明蚊帐是对减少malarial的发生有用的,那么官员在不愿意用蚊帐就不会是因为他防不了蚊子了··这样就反对了题目的条件  ------还有题目也没有说蚊帐可以防蚊子也只能说是一个常识,那么C答案就无关了·

虽然我认为你说的没错,而且我可能也太钻牛角尖了,可按照必须严格按题目所给的信息来做题的原则,我还是没法直接把蚊帐可以防蚊子当一个常识。

继续求解中………………

 其实有了这些例子 我反倒能说服你了。“他声称除了家他一无所有。” 那就是说他还是有家的吧?
                                                                               "other than mos", 那说明蚊子还是能防止的。 other than 后面的东西是positive 的。  LZ体会下,rather than和other than 有区别吗?
这篇文章的逻辑链是怎样的? 能防蚊---》还是不要用。我觉得你在挖空心思要攻击前提。其实相反,GMAT要我们攻击推理部分(箭头),或者结论(还是不要用。open for your question~
