A)acknowledge F)genius K)puzzled
B)assess G)highly L)status
C)confused H)permanent M)surprising
D)endure I)possess N)thoroughly
E)extremely J)presence O)unique
答案解析
26.O)【语义判断】空格所在句意为：但一段关系是由两个______个体组成的。而下一句是关于这些个体的个性特征，由此可知，本句表达的是一段关系由两个不同的个体组成，因此本空应填入含有“不同的，独特的”意义的形容词，由此确定本题答案为O)unique 。
27.I)【语义判断】or意为“或者”,表示选择关系，且后面出现了more orless这组意义相反的词，所以此处的动词应该与 lack“缺乏”意思相反，故本空应填入含有“拥有”意义的动词，由此确定本题答案为I)possess。
28.D)【语义判断】空格所在句意为：这些个体拥有或缺乏的个性特征通常可以让一段关系更可能或更不可能_______。综合前一句可知，一段关系包括两个不同的个体，他们各自的个性特征会影响他们的关系，结合备选动词可知，本空填入含有“持续，持久”意义的动词更合适，由此确定答案为D)endure。
29.C)【语义判断】空格所在句的意思是：谦逊有时会被缺乏自信。由常识可知，如果一个人太谦虚，可能会被误认为是缺乏自信。因此本空应填入含有“混淆，误认为”意义的词，由此确定答案为C)confused.K)puzzled与confused意思相近，但不能与with搭配使用，因此排除。
30.J)【语义判断】空格所在句意为：研究人员已经意识到，谦虚通常标志着非常令人钦佩的个人品质的______。将备选项中的三个名词分别代入空格，只有J)presence“存在”符合句意，因此为正确答案。
31.B)【语义判断】空格所在句意为：谦逊意味着你有能 力准确地______自己的不足，同时也不否认自己的技能和优势。此处应选择一个能与副词 accurately 以及后面宾语 deficiencies搭配的动词。综合备选项可知，B)assess 与deficiences搭配，意为“评估不足”,符合句意，为本题答案。
32.F)【语义判断】空格所在句意为：你可能意识到自己很聪明，但也明白自己不是一个______。备选项中有三个名词，其中符合句意的只有F)genius“天才”,故为本题答案。
33.A)【语义判断】空格所在句意为：他们能够错误，发现那些远称不上完美的事物的价值，并找出需要改进的地方。由上一句可知，谦逊的人不会忽视、避免或试图否认自己的局限或不足。那么这里表示的意思应为能够承认错误，从而改进。 因此确定答案为A)acknowledge“承认”。
34.M)【语义判断】空格所在句意为：谦逊似乎是人际关 系中的一笔巨大财富，这也许并不______。由 第二段可知，谦逊是一个非常好的性格特点，那么谦逊对人际关系很重要，这一点就不足为奇了，因此本空应填入含有“惊奇，惊讶”意义的形容词，由此确定答案为M)surprising。
35.G)【语义判断】空格所在句的意思是： 一项研究发现，人们倾向于_______评价配偶的这一品质。将备选项中的三个副词分别代入空格，只有G)highly“非常赞许地”使句意通顺，因此确定答案为G)highly。rate highly意为“高评价，评价很高”。
Section B
Directions: In this section,you are going to read a passage with ten statements attached to it. Each statement contains informationgiven im one of the paragraphs.Identify theparagraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter Answer the questions by marking the correspondng letter on Answer Sheet 2.
There's a stress gapbetween men and women
A)“I used to work very hard.I loveto create things,grow them and solve problems,“said Meng Li,a successful app developer in San Francisco.“I didn't really care about my mind and my body until they decided to go on strike.”
B)Ms.Li said her stress led to sleeplessness.When she did sleep,she experienced “problem-solving dreams,”which left her feeling unrested when she woke up.“After I became a first-time mother,I quickly realized I was so busy caring for other people and work that I felt likeI'd lost myself,”she said.
C)It's a common story-one we frequently ridicule and readily dismiss,for example, by claiming that women tend to complain more than men,despite the growing sum of research that underlines the problem.Womenare twice as lkely to suffer from severe stress and anxiety as men,according to a 2016 study published in The Journal ofBrain &Behavior.The American Psychological Association reports a gender gap year after year showing that women consistently report higher stress levels.Clearly a stress gap exists.
D)“The difference is not really news to me,as a clinical psychologist,”said Erin Joyce, a women and couples therapist in Los Angeles.“It's beenwell documented in extensive research over the years that prevalence rates for the majority of the anxiety disorders are higher in women than men.”Some people may argue that this is merely reported data,and they say many men feel the same pressures as women in terms of fulfilling responsibilities at work and home.In other words,we're all really,really stressed.
E)“The difference,however,is in the nature and scope of these responsibilities in the home environment in particular,”Dr.Joyce said.For example,the United Nations reported that women do nearly threetimes as much unpaid domestic work as men.The problem is,housework is often overlooked as work,even though it is often as laborious (or in some cases,moreso)as any paid job.As the scholar Silvia Federici put it in 1975, the unpaid nature of domestic work reinforces the assumption that “housework is not work,thus preventing women from struggling against it.”
F)It's not just inside the home,though.Research from Nova Southeastern University found that female managers were more likely than male managers to display “surface acting,”or forcing emotions that are not wholly felt.“They expressed optimism, calmness and sympathy even when these were not the emotions that they were actually feeling,"the study said.
G)Surface acting is a prime example of “emotional labor,”a concept that the writer Jess Zimmerman made familiar in a 2015 essay.The essay sparked a massive thread on the internet community blog MetaFilter.Hundreds of women spoke up about their own experience with emotionallabor:the duties that are expectedof them,but go unnoticed. Theseinvisible duties become apparent only when you don't do them.Like domestic labor,emotionallabor is generally dismissed and not labeled work.But research shows it can be just as exhausting as paid work.Emotional labor can lead to difficulty in sleeping and family conflict.Sure,circumstantial stress,like losing a job,may lead to these same issues.But emotional labor is not circumstantial.It's an enduring responsibility based onthe socialized gender role of women.
H)Like Ms.Li,manywomen try to managethe added stress to reach what Dr.Joyce said was an unattainable ideal.“Some professional women aim to do it all.They want to reach the top of the corporate ladder and fly like supermom,”she said When women don't reach this ideal,they feelguilty;and evenmore stressed.After herown struggle with this,Ms.Li took a step back and used her experience to build Sanity &Self,a self-care app and platfom for overworked women."The realizations I had in that process helped me gain insights and ultimately gotme ready to integrate self-care into my daily life,“she said
I)The stress problem extends beyond mental health when you consider the link between stress,anxiety and heart health.Worse,most of what we know about heart disease comes from studies involving men.However,“there are many reasons to think that it's different in women,”Harvard Medical School reported.For example,women are more likely toexperience disturbed sleep,anxiety and unusual fatigue before a heart attack.Stress is so normalized that it is easy for women to shrug off those symptoms as simply the consequences of stress.Many women also do not experience chest pain before a heart attack the way men do,which leads to fewer women discovering problematic heart issues.Harvard reports that women are“much more likely than men to die within a year of having a heart attack”and““many women say their physicians sometimes don't even recognize the symptoms.”
J)The good news is,women are more likely than men to takecharge of their stress and manage it,the American Psychological Association reports.The concept of self-care, at itscore,is quite simple.“The basics of adequate sleep,healthy diet and exercise are a good place to start,”Dr.Joyce said.“Support from trusted relationships is vital. This includes professional support from various health and wellness providers if stress is becoming increasingly overwhelming.”
K)Disconnecting from work and home responsibilities is also obviously important.But it's much easier said than done.It is important to understand what causes your stress in the firstplace.“Get really specific with what's stressing you out,”Ms.Li said. “We often chalk up our stress to broad experiences like work.But work stress can take many different forms.Is a colleague being disrespectful ofyour time?Is a boss undermining your day-to-day control over decision making?These are different causes o stress and can benefit from different kinds of self-care.”
L)Ideally,your spouse or partner will be supportive,rather than dismissive,of yourstress It is important to talk through these issues before they come to a head.“Women working outside of the home should make an effort to have a conscious conversation with their partners about more equitable sharing of household and family responsibilities,”Dr.Joyce said.
36.Somecareerwomen who aim high tend to feel guilty ifthey fail to achieve their goals.
37.The unpaid housework done by women is triplethat doneby men
38.It is reported that womenconsistently suffer more from severe stress than men.

40.One study showed that women managers often expressed positive emotions that they didn't really feel.
41.Women tend to mistake signs of heart attacks for symptomsof stress.
42.Fora time an app developer in America was so busy attending to work and family that she suffered from sleeplessness.
43.The emotional labor women do is noticed only when it is not done.
44.Dr.Joyce suggests that apart from self-care,women should seek professional support if they experience severe stress.
45.Some people believe that there may not exist a stress gap between men and women.

Section C
Directions: There are 2 passages in this section.Each passage is followed bysome questionsor mfinished statements.For each of them there are four choices marked A),B),C)and D) You shoulddecide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line throughthe centre.
Passage One
Questions 46 to 50 are based on the following passage.
As many office workers adapt to remote work,cities may undergo fundamental change if offices remain under-utilized.Who will benefit if working from home becomes the norm?
Employers argue they make considerable savings on real estate when workers shift from office to home work.However,these savings result from passing costs on to workers.
Unless employees are fully compensated,this could become a variant of parasitic (寄生的)capitalism,whereby corporate profits increasingly rely on extracting value from the public—and now personal—realm,ratherthan on generating new value.
Though employers are backed by a chorus of remote work advocates,others note the loneliness,reduced productivity and inefficiencies of extended remote work
If workingfrom home becomes permanent,employees will have to dedicate part of their private space to work.This requires purchasing desks,chairs and office equipment.
It also means having private space dedicated to work:the space must be heated,cleaned,maintained and paid for.That depends on many things,but for purposes of illustration,I have run some estimates for Montreal.The exercise is simple but important,since it brings these costs out of the realm of speculation into the realm of meaningful discussion.
Rough calculations show that the savings made by employers when their staff works from home are of similar value to the compensation workers should receive for setting up offices at home.
What does this mean for offices in cities?One oftwo things may happen:Employers pass these costs onto employees.This would be a form of expropriation(侵占),with employees absorbing production costs that have traditionally been paid by the employer.Thisrepresents aconsiderable transfer of value from employeesto employers
When employees are properly compensated,employers'real estate savings will be modest.If savings are modest,then the many advantages of working in offices—such as lively atmosphere,rapidity of communication,team-building and aclimatization (适应环境)of new employees—will encourage employers to shelve the idea of remote work and,like Yahoo in 2013,encourage employees to work most of the time from corporateoffice space.
46.What does the author say about working from home?
A)Itwillbecome the nom sooneror later.
B)It requires employees to adapt promptly.
C)It benefits employers at the expense of employees
D)It will force cities to transform their infrastructure.
47.Why do some people oppose working from home?
A)It discourages team spirit.
B)It invadesemployees'privacy.
C)It undermines traditional values.
D)It negatively impacts productivity.
48.Why did the authorrun the estimates for Montreal?
A)To provide convincing data for serious discussion.
B)Toillustrate the ongoing change in working patterns.
C)To show the impact of remote working on productivity.
D)To exemplify how remote working affects theeconomy.
49.What can weconclude fom the author's calculations?
A)There is no point in transferringoffice work to working from home
B)Employees can benefit as much from remote workingastheir employers
C)Employers'gain fiom remote working should goto employees as compensation.
D)Effective measures should betaken to motivate employees to set up offices at home
50.What isthe author's opinion on working from home?
A)It should be avoided if possible.
B)It is only a temporary measure.
C)It can reduce companies'real estate costs
D)It may affect employees'corporate loyalty.
答案解析
46.【定位】由题干中的the author和working from home定位到第一、二段。
C)【精析】细节辨认题。第二段指出，雇主们认为，当工作人员从办公室转到家中工作时，他们在房地产方面节省了大量资金。然而，这些节省下来的资金来自于将成本转嫁到工人身上。由此可见，远程工作这一模式虽然使雇主从中受益，但是却以牺牲雇员的利益为代价，故答案为C)。
47.【定位】由题干中的some people oppose working from home定位到第四段。
D)【精析】推理判断题。定位段提到，尽管雇主得到了远程工作倡导者的异口同声的支持，但其他人注意到长期的远程工作所带来的孤独感、生产率降低和效率低下。由此可知，远程工作模式并不是受到大家的一致肯定，也有人持反对意见，而这些反对意见就包括：孤独感、生产率降低和效率低下，所以人们反对的原因是认为它会对生产力产生负面影响，故答案为D) 。
48.【定位】由题干中的 the authorrun the estimates for Montreal定位到第六段最后一句。
A)【精析】细节辨认题。定位句指出，这项工作很简单但很重要，因为它将这些成本从推测领域带到了有意义的讨论领域。由此可见，作者之所以对蒙特利尔进行估算，是为有意义的讨论提供真实的数据，故答案为A)。
49.【定位】由题干中的the author's calculations定位到第七段。
C)【精析】细节辨认题。定位段提到，粗略计算表明，当员工在家工作时，雇主所节省的费用与员工在家设立办公室所应获得的补偿金额相当。由此可知，雇主所节省下来的费用应该给予雇员，补偿他们设立办公室的费用，故答案为C)。
50.【定位】由题干中的author's opinionon working from home定位到最后一段。
A)【精析】细节辨认题。定位段指出，如果雇员得到适当的补偿，雇主的房地产节省的资金就少了，那么在办公室工作的许多优势，例如活跃的气氛、快速的沟通、团队建设和新员工对环境的适应，都将鼓励雇主搁置远程工作的想法，就像2013年的雅 虎一样，鼓励员工大部分时间在公司办公。由此可见， 一旦雇主需要对远程工作的员工进行补偿，那么对于雇主而言，远程工作的弊端就大于利益，那么远程工作对于雇主和雇员双方都没有太大的好处。因此，作者支持在办公室工作，故答案为A)。
Passage Two
Questions 51 to 55 are based on the following passage
The human thirst for knowledge is the driving force behind our successful development as a species.But curiosity can also be dangerous,leading to setbacks or even downfalls.Given curiosity's complexity,scientistshave found ithard to define
While pinning down a definition has proven tricky,the general consensus is it's some means ofinformation gathering.Psychologists also agree curiosity is intrinsicalby(内在地) motivated.
Curiosity covers such a large set of behaviors that there probably isn't any single “curiosity gene”that makeshumans wonder aboutandexplore their environment.That said, curiosity does have a genetic component.Genes and the environment interact in many complex ways toshape individuals and guide their behavior,including theircuriosity
Regardless of their genetic makeup,infants have tolearn an incredible amount of information in a short time,and curiosity is one of the tools humans have found to accomplish that gigantic task.
Hundreds of studies show that infants prefer novelty.It's whatmotivates non-human animals,human infants and probably human adults to explore and seek out new things before growing less interested in them aftercontinued exposure.
But curiosity often comes with a cost.
In some situations,the stakes are low and failure is a healthy part of growth.For instance,many babies are perfectly proficient crawlers,but they decide to try walking because there's more to see and do when they stand upright.But this milestone comes at a small cost.A study of 12-to 19-month-olds learning how to walk documented that these children fell down a lot.Seventeen times per hour,to be exact.But walking is faster than crawling,so this motivates expertcrawlers to transitionto walking.
Sometimes,however,testingout a new ideacan lead to disaster.For instance,the Inuit people of the Arctic regions have created incredible modes to deal with the challenges of living in northern climates,but what we forget about are the tens of thousands of people that tried and failed to make it inthose challenging landscapes.
51.What does the author say about curiosity?
A)It istoo complex fornon-scientists tounderstand.
B)It is the force that pushes human society forward.
C)It is a unique trait specific to the human race.
D)It is oftenthe majorcause for human failures.
52.What is the general understandingof curiosity?
A)It motivates people to seekinformation.
B)It is destined to transform human genes.
C)It does people more good than harm.
D)It underlies all human behaviors.
53.What do we leamabouthow genes shapepeople's behavior?
A)Theydetermine people's way of thinking.
B)Theyaccount for age differences in learning.
C)They enable people to undertakemassivetasks.
D)They work in conjunction with the environment.
54.What do numerous studies show about infants?
A)They are far more curious than adults.
B)They preferto go after allthatis novel.
C)They have different interests than adults.
D)Theyshow non-human animal behaviors.
55.What does the example of the Inuit people of theArctic regions illustrate?
A)The costo humans'curiosity to explore.
B)The incredible harshness of cold weather.
C)The innovative ideas stemming from curiosity
D)The importance of learning from past failures.
答案解析
51.【定位】由题干中的the author和curiosity定位到首段第一句。
B)【精析】细节辨认题。定位句指出，人类对知识的渴望是我们作为一个物种成功发展背后的驱动力。由此可见，作为一个物种，我们之所以不断向前发展，是因为有好奇心这一驱动力，故答案为B)。
52.【定位】由题干中的the general understanding of curiosity定位到第二段第一句
A)【 精析】细节辨认题。定位句提到，虽然事实证明 给好奇心下定义很难，但大家普遍认为好奇心是 一种收集信息的手段。由此可知，好奇心可以激励人类去寻找信息，故答案为A)。
53.【定位】由题干中的 we learn about how gencs shape people's bchavior定位到第三段第三句。
D)【精析】细节辨认题。定位句指出，基因和环境以许多复杂的方式相互作用，塑造个体并指导他们的行为，包括他们的好奇心。由此可见，基因之所以可以影响人类的行为，是与环境相互作用的结果，故答案为D)。
54.【定位】由题干中的 numerous studies show about infants 定位到第五段第一句。
B)【精析】细节辨认题。第五段第一句提到，数百项研究表明，婴儿更喜欢新奇的事物。这是促使非人类动物、人类婴儿，甚至可能是人类成年人探索和寻找新事物的动力，而在持续接触之后，他们对新事物的兴趣会减弱。由此可见，婴儿比成年人更喜欢追求新奇的东西，故答案为B)。
55.【定位】由题干中的 the Inuit people of theArctic regions定位到最后一段。
A)【精析】推理判断题。最后一段第二句中的For instance说明该句是例证，主要说明第一句的观点。第一句指出，有时候测试一个新想法可能会导致灾难。由此可见，驱使人类不断进行探索的好奇心也会给人类带来负面的影响，故答案为A)。
