新prep破解第二套，122题~ 严重不能理解啊……

Until now, only injectable vaccines against influenza have been available.  arents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated.  A new influenza vaccine, administered painlessly in a nasal spray, is effective for children.  However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.

Which of the following is an assumption on which the argument depends?

A. Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.

B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.

C. The injectable vaccine is affordable for all adults.

D. Adults do not contract influenza primarily from children who have influenza.

E. The nasal spray vaccine is not effective when administered to adults.

这道题ABC肯定是直接扔掉了。DE这块，我真是觉得E更有道理。D说adults不会从孩子那里得到influenza。但是题目中已经说过，他人都打了疫苗了啊？就是contract也没什么关系了。E这条线呢，我是这样想的。小孩得influenza没什么问题，所以这新出的喷剂也就没必要用了。但是大人得这个病有问题，大人又得打疫苗。如果这个喷剂对大人有效，大人不用打疫苗，这药也就不能说没用了……

我不知道是这道题我哪里是不是理解错了……郁闷啊……请大家指点啊！！！

忽然有点理解了，commonly vaccinated不代表全部大人都免疫， 而D选项断了小孩会传染给大人的可能性，也就是说更没有必要给小孩吸疫苗了。

对啊，文中已经提到adults are commonly vaccinated,就算小孩会传染给大人，但是大人已经免疫了，被传染也不会得病啊。。

你说：扎针治病，你妈说疼不让你扎，但是她自己扎说自己得病难受。现在好了直接吸粉就能给孩子治病，你们爹妈说孩子得了病也不难受，就不给孩子治病了。这咋回事？－－－我说：俺妈说孩子的病传染不了大人，用不着给孩子治病。／俺妈说吸粉不能给她治病

我认为楼主之前的思考是正确的，而且曼哈顿说E是正确选项。。。

who are at risk of serious complications from influenza, are commonly vaccinated 但是题目特别说大人已经打过疫苗了，小孩打不打的关键，按正常思维就是他们自己的小命受不受流感并发症影响。所以D选项也不太对呀。

Until now, only injectable vaccines against influenza have been available. Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated. A new influenza vaccine, administered painlessly in a nasal spray, is effective for children. However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.                    

Which of the following is an assumption on which the argument depends?
A Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.
大人能接受注射型也能接受鼻喷型疫苗。与应用鼻喷的好处无关，杀。
B The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
无关信息，杀  
C The injectable vaccine is affordable for all adults.  
无关
D Adults do not contract influenza primarily from children who have influenza.  
小孩不传染给大人流感。小孩子自己打不打无所谓，因为他们都不会有流感反应。如果他们不给大人传染病，小孩子就更没有理由打鼻喷式疫苗了，对。
E The nasal spray vaccine is most effective when administered to adults.  
莫名奇妙的比较。杀。文中问的是小孩子打疫苗的必要性。
目的：解释不广泛应用鼻喷在小孩子身上的合理性。
逻辑：背景／小孩子怕疼，小孩子没有严重的流感症状，大人有流感症状，大人都接受注射型疫苗。
现在有一个不疼的鼻喷疫苗，可以给小孩子有效的保护。但是事实是小孩子没有严重的流感症状，打不打对小孩子都一样。然而对大人，如果小孩子对大人有传播流感的能力，小孩子就必须打疫苗。如果小孩子不传播给大人流感，那小孩子打不打疫苗都行。D选项否定了小孩子必须打疫苗的唯一必要，所以这种鼻喷型疫苗，小孩无需打。
没有public benefit.
