9、wronged cfooled dmocked18. aforced bwilling c hesitant dentitled 19. ain contrast bas a result con the whole dfor instance20. ainflexible bincapable cunreliable dunsuitable 1.【答案】c【解析】該題選擇的是介詞，與后面的 many worthwhile things 一塊做后置定語修飾前面的condition, 表明對于許多重要事情來說是一個必要的條件。而 a 選項 from（來自于），c 選項 like（像） d 選項

10、on （關于）均語義不搭。2.【答案】a【解析】此處考察語義一致和對上下文辨析的問題。該空是做 put 的賓語，通過前面的 on the onehand, its a necessary condition _(1) many worthwhile things: child care, friendships, etc. ( 一方面,信任對許多重要事情來說是必要條件，比如照看孩子，友誼等 )；on the other hand 可以得知該題仍然是在講述關于主題 trust 的問題，所以只有 faith（信任）最合適。而 b 選項 concern（關心，關注）， c 選項 attention

11、（注意），d 選項 interest （興趣，利益）均不符題意。3.【答案】d【解析】此處考察詞義辨析。前文說到 putting your _in the wrong place often carries a high_（把放在錯誤的地方通常會帶來巨大的），可以知道該空肯定也是填貶義，但肯定不能是 debt 債務這種具體含義，所以只能選 price ，并且 carries a high price 也指付出高昂的代價。4.【答案】b【解析】此題考察上下文邏輯關系。上一段分析的是信任的利弊，該段所指內(nèi)容 _, why do wetrust at all?（我們?yōu)槭裁磿湃危浚┧圆捎昧诉f進關

12、系，進一步說明信任的具體內(nèi)容。只有 d 選項then(然后，那么) 最符合語義搭配。而 a 選項 again（再次）表示強調；b 選項 instead（然而）表轉折； 而 c 選項 therefore （因此）表結果，均不符合。5. 【答案】d【解析】此處再一次考察邏輯關系。該空 _ people place their trust in an individual or aninstitution, their brains release oxytocin ，a hormone （_人們信任一個人或者一個機構，大腦都會 釋放一種荷爾蒙） ,只有 when （當時）符合上下文語境和邏輯語境。

13、6. 【答案】b【解析】該題是考察定語從句的動賓搭配問題。上一句說當人們產(chǎn)生信任感，大腦就會產(chǎn)生一種荷爾蒙，a hormone that _(6) pleasurable feelings 這個 that 就是定語從句，指這種荷爾蒙能 _ 令人愉悅的感覺，只能是 produce 最符合語境。7.【答案】c【解析】考察詞義辨析。該空所填為動詞，并且要求與之后的 with 形成搭配。 and triggers theherding instruct that leads sheep to flock together for safety and prompts humans to _withon

14、e another. 說明這種荷爾蒙能夠引發(fā)一種群居本能，這種本能能讓羊群聚在一起， and 的后面的內(nèi)容 也與前面的 flock together 同義復現(xiàn)。所以只有 connect 最符合語境。8. 【答案】d【解析】該題考察固定搭配。與 exposure to 構成固定搭配的關系。表示“接觸”9. 【答案】b【解析】該題考察上下文語義。上文中說到這種荷爾蒙會給人帶來一種愉悅的情緒，通過這個結論， 可以得出這種荷爾蒙能讓人有讓人信任的情緒 /心緒。只有 mood 是最合適的答案。10.【答案】a【解析】此處仍然是考察上下文語境。上文中 in a study, researchers spr

15、ayed oxytocin into thenoses of half the subjects; 能從下文得知這也是只本句講另外一組受試者。conuterparts 表示對應物， 對應的人。11.【答案】b【解析】此處考察上下文邏輯關系。從后文中的 also 可以看出前后一致的關系。前文對于這種天賦 都是褒義的色彩，所以答案此時應該是 lucky 。12.【答案】b【解析】同樣也是因為 also ，說明前后一致關系。只能選擇 protect.13.【答案】a【解析】考察固定搭配。 a canadian study found that children as young as 14 mont

16、hs candifferentiate _ a credible person and a dishonest one. 選則 between 意為： 14 個月大的孩子能 在誠實和不誠實的人之間進行區(qū)分。14.【答案】c【解析】考察搭配。結合原文語境，“sixty toddlers were each_to adult tester holding a plastic container ”選項 c“be introduced to sth ”表示“初次認識某物?！狈显恼Z境。15.【答案】d【解析】本題考察借此搭配及詞義復現(xiàn)。根據(jù)原文“ what s in here? ”before l

17、ooking into thecontainer.each subject was then invited to _. ” 選項 d 與前文所表達的 in here 和 looking into 相關。因此 d 為正選。16.【答案】a【解析】本題考察詞義復現(xiàn)。根據(jù)語境“half of them found a toy; the other half 16 the containerwas empty. ”這是用分好并列連接的兩個句子，屬于并列關系。因此，前半句講一般的受測者在盒子里面找到了玩具，后半句在肯定其他人會怎么說。像個小分局的結構基本一直。因此本題填入的含義應 該與 found 含

18、義相同。因此， a 選項發(fā)現(xiàn)為正選。17.【答案】c【解析】根據(jù)本題語境，此句在破折號后面，是對前面的意思解釋說明。前面提到了另一半人發(fā)現(xiàn)盒子是空的，并且易世達測試者對他們怎么樣。既然盒子是空的，那么肯定認識到測試者是在戲弄他們，所以對此題必須要理解測試者是主語，賓語是 them 指的是受測者。主語的含義決定了謂語的含義為戲 弄。因此 c 選項為正選。18.【答案】b【解析】考察搭配。根據(jù)句子結構我們可以看出逗號之前是一個介詞短語，意為在所有沒有被戲弄過的孩子里面，大多數(shù)的孩子在習得一種新技能的時候與測試者的合作是如何的。 demonstrating thatthey trusted his leadership 表明這些孩子信任他的領導。因此，既然信任他們就表示愿意合作。所 b 選項 willing to do 構成固定搭配。19.【答案】a【解析】本題考察邏輯關系。根據(jù)原文語境“”only five
