9、 incapableC. unreliableD. unsuitable1.【答案】C。解析：此处考查介词的用法。Its a necessary condition _ many worthwhile things (信任是一个必要条件_许多重要事情) 此处应该是说，信任对许多重要事情来说是一个必要条件。C选项for(对.来说)符合语义，故为正确答案；D选项from(来自于)，B选项like(像.)，A选项on(关于)语义不恰当，故排除。2.【答案】A。解析：此处考查词义辨析和中心一致性原则。第一段首句提出主题句：trust is a tricky business (信任是一个奇怪的东西)。
10、后面进一步对该主题句进行解释说明：On the one hand, its a necessary condition _ for _ 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)，这句话在说信任的好处。On the other hand, putting your _ in the wrong place often carries a high _. (另一方面，把.放在错误的地方往往会带来巨大.)，显然这句话依旧在解释主题词“trust”，只有A选项faith
11、(信任、忠诚)与trust属于近义词复现，故正确答案为A。3.【答案】D。解析：此处考查词义辨析。第一段首句提出主题句：trust is a tricky business(信任是一个奇怪的东西)。后面进一步对该主题句进行解释说明：On the one hand, its a necessary condition _ for _ 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)，这句话在说信任的好处。On the other hand, putting your _
12、in the wrong place often carries a high_. (另一方面，把.放在错误的地方往往会带来巨大.)，显然这句话依旧在解释主题词“trust”，并且根据空格所在句中的关键词“wrong place”，本句应该在说信任不当的弊端，所以空格处应该填入一个负向感情色彩的词，故benefit和hope排除，而debt(债务)带入之后语义不当，故正确答案为D. price(代价)。4.【答案】B。解析：此处考查逻辑关系。上段讲述的是信任的好处和信任不当的弊端。第二段段首提出问题：“_我们为什么要信任”。只有B选项then(那么)填入后能形成顺畅的语义和逻辑关系。故正确答案
13、为B。again(再次)表示强调；instead(但是、然而)表示转折；therefore(因此)表示结果，不符合要求，故排除。5.【答案】D。解析：此处考查逻辑关系。空格所在句含义为：_人们信任一个人或一个组织机构，他们的大脑会释放催产素。只有D选项when(当时候)填入后符合逻辑要求，故正确答案为D。其他三个选项unless(如果不)表条件，although(尽管)表让步，until(直到.)表时间，带入后均语义不通顺，故排除。6.【答案】B。解析：此处考查动宾搭配问题。上文指出：When people place their trust in an their brains releas
14、e oxytocin, a hormone.上文指出当人们产生信任感，大脑就会产生一种荷尔蒙，后面是定语从句，句内的动宾搭配，可推知这个荷尔蒙能产生令人愉悦的情绪，并且与后面的trigger同义复现，因此B. produce 正确。7.【答案】C。解析：此处考查上下文信息照应题。上文讲到这种荷尔蒙能够激发一种群居本能，the herding instinct that leads sheep to flock together for safety and promote with one another，这种本能有两个作用，并用and 连接，所以复现同义and 前面的flock togeth
15、er. 因此选择C. connect。8.【答案】D。解析：此处考查上下语境下的名词介词搭配问题。根据上文的结论，下文实验展开分析，Swiss scientists have found that exposure to this hormone puts us.所以研究中要求受试者要先处于这种环境中，所以名词exposure to 构成搭配语义关系，表示“接触”的意思，因此选择to。9.【答案】B。解析：此处考查上下文的信息对应和句内信息对应。上文提到身体会产生荷尔蒙，会给你带来一种愉悦的情绪pleasurable feelings，这是上文结论。实验中exposure to this hormone puts us in a trusting ，因此，根据上下文，试验中，处于这种荷尔蒙环境中，会给人带来信任的情绪；语气；心境。因此选择 mood。10.【答案】A。解析：此处考查上下文的信息对应和句内信息对应。上文指出，In
