Subsequent experiments replicated this effect with other stimuli, (9) the sound of fingernails on a chalkboard and photographs of disgusting insects.The drive to (10) is deeply ingrained in humans, much the same as the basic drives

7、liableDunsuitable1.【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 like（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 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 putt

8、ing 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 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 anindividual 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

9、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
