Ainflexible Bincapable Cunreliable Dunsuitable1.【答案】C【解析】该题选择的是介词，与后面的many worthwhile things一块做后置定语修饰前面的condition,表明对于许多重要事情来说是一个必要的条件。而A选项from（来自于），C选项li
10、ke（像）D选项on（关于）均语义不搭。2.【答案】A【解析】此处考察语义一致和对上下文辨析的问题。该空是做put的宾语，通过前面的On the one hand, its a necessary condition _(1) many worthwhile things: child care, friendships, etc. (一方面,信任对许多重要事情来说是必要条件，比如照看孩子，友谊等)；on the other hand可以得知该题仍然是在讲述关于主题trust的问题，所以只有faith（信任）最合适。而B选项concern（关心，关注），C选项attention（注意），D选项
11、interest（兴趣，利益）均不符题意。3.【答案】D【解析】此处考察词义辨析。前文说到putting your _in the wrong place often carries a high _（把放在错误的地方通常会带来巨大的），可以知道该空肯定也是填贬义，但肯定不能是debt债务这种具体含义，所以只能选price，并且carries a high price也指付出高昂的代价。4.【答案】B【解析】此题考察上下文逻辑关系。上一段分析的是信任的利弊，该段所指内容_, why do we trust at all?（我们为什么会要信任？）所以采用了递进关系，进一步说明信任的具体内容。只有
12、D选项then(然后，那么)最符合语义搭配。而A选项again（再次）表示强调；B选项instead（然而）表转折；而C选项therefore（因此）表结果，均不符合。5.【答案】D【解析】此处再一次考察逻辑关系。该空_ people place their trust in an individual or an institution, their brains release oxytocin，a hormone（_人们信任一个人或者一个机构，大脑都会释放一种荷尔蒙）,只有when（当时）符合上下文语境和逻辑语境。6.【答案】B【解析】该题是考察定语从句的动宾搭配问题。上一句说当人们产生
13、信任感，大脑就会产生一种荷尔蒙，a hormone that _(6) pleasurable feelings这个that就是定语从句，指这种荷尔蒙能_令人愉悦的感觉，只能是produce最符合语境。7.【答案】C【解析】考察词义辨析。该空所填为动词，并且要求与之后的with形成搭配。and triggers the herding instruct that leads sheep to flock together for safety and prompts humans to _with one another.说明这种荷尔蒙能够引发一种群居本能，这种本能能让羊群聚在一起，and的后
14、面的内容也与前面的flock together同义复现。所以只有connect最符合语境。8.【答案】D【解析】该题考察固定搭配。与exposure to构成固定搭配的关系。表示“接触”9.【答案】B【解析】该题考察上下文语义。上文中说到这种荷尔蒙会给人带来一种愉悦的情绪，通过这个结论，可以得出这种荷尔蒙能让人有让人信任的情绪/心绪。只有mood是最合适的答案。10.【答案】A【解析】此处仍然是考察上下文语境。上文中In a study, researchers sprayed oxytocin into the noses of half the subjects;能从下文得知这也是只本句讲
15、另外一组受试者。conuterparts表示对应物，对应的人。11.【答案】B【解析】此处考察上下文逻辑关系。从后文中的also可以看出前后一致的关系。前文对于这种天赋都是褒义的色彩，所以答案此时应该是lucky。12.【答案】B【解析】同样也是因为also，说明前后一致关系。只能选择protect.13.【答案】A【解析】考察固定搭配。A Canadian study found that children as young as 14 months can differentiate _ a credible person and a dishonest one.选则between意为：14个月大的孩子能在诚实和不诚实的人之间进行区分。14.【答案】C【解析】考察搭配。结合原文语境，“Sixty toddlers
