Section A

Directions: In this section,there is a passage with ten blanks.You are required to select one word for each blank from a list of choices given in a wond bank following the pasage.Read the passage through carefully before making your choices.Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre.You may not use any of the words in the bank more than once.

When my son completes a task, I can't help but praise him. It's only natural to give praise where praise is due, right? But is there such a thing as too much praise?

According to psychologist Katherine Phillip, children don't benefit from 26 praise as much as we'd like to think. "Parents often praise, believing they are building their child's self-confidence. However, over-praising can have a 27 effect," says Phillip. "When we use the same praise 28, it may become empty and no longer valued by the child. It can also become an expectation that anything they do must be 29 with praise. This may lead to the child avoiding taking risks due to fear of 30 their parents."

Does this mean we should do away with all the praise? Phillip says no. "The key to healthy praise is to focus on the process rather than the 31. It is the recognition of a child's attempt, or the process in which they achieved something, that is essential," she says. "Parents should encourage their child to take the risks needed to learn and grow."

So how do we break the 32 of praise we're all so accustomed to? Phillip says it's important to 33 between “person praise” and "process praise". “Person praise is 34 saying how great someone is. It's a form of personal approval. Process praise is acknowledgement of the efforts the person has just 35. Children who receive person praise are more likely to feel shame after losing,” says Phillip.

答案解析

26. 答案 B

空格前為介詞from, 空格后為名詞 praise, 因此應(yīng)填入形容詞?？崭袼诰湟鉃?，孩子從表揚中得到的好處并不像我們想象的那么多。該段是用心理學(xué)家的話來說明的確是存在過度 表揚的。因此，應(yīng)填入含有“過多的，大量的”意思的形容詞，故選B)constant “持續(xù)不斷的”。

27. 答案 G

空格前為不定冠詞a,空格后為名詞 effeet,因此應(yīng)填入形容詞。空格前的However說明該句與前一句構(gòu)成轉(zhuǎn)折關(guān)系，上一句提到，父母認為表揚孩子可以培養(yǎng)孩子的自信心，因此本 句是說過度表揚會有“害處”。故選G)negative “負面的，消極的”。

28. 答案 K

空格所在從句基本成分完整，且空格處位于從句句尾，因此應(yīng)填入副詞。此處仍是心理學(xué)家的觀點，因此應(yīng)承接上一句的內(nèi)容，說明過度表揚的害處?？崭袼诰湟鉃?，當我們使用同樣的表揚時，它可能會變得空洞，不再被孩子重視，故選K)repeatedly“反復(fù)地，多次”。

29. 答案 L

空格前為be,空格后為介詞短語，因此應(yīng)填入動詞的分詞形式或形容詞。空格所在句意為，表揚也可能會成為一種期望，即他們所做的任何事情都必須表揚。因此，應(yīng)填入含有“給予”意思的詞。be rewarded with sth. 表示“獲得某事物的獎勵”,符合語境。故選 L)rewarded“獎賞，給予”。

30. 答案 C

空格前為介詞of, 空格后為名詞詞組 their parents,因此應(yīng)填入動詞的-ing 形式。由上文可知，孩子期待做什么事都能得到父母的表揚。如果他們失敗了，父母可能會失望，他們可能 得不到表揚。所以此處是指，孩子可能會因害怕讓父母“失望”而避免冒險。故選 C)disappointing “使失望”。

31. 答案 H

空格前為冠詞 the, 因此應(yīng)填入名詞?？崭袼诰湟鉃?，合理表揚的關(guān)鍵是關(guān)注過程而不是____。應(yīng)填入一個與 process“過程”意思相反的詞，故選H)outcome “結(jié)果，后果”。

32.答案 I

空格前為冠詞the, 空格后為介詞of, 因此應(yīng)填入名詞。該段列舉了兩種表揚方式，并說明 “對過程的表揚”是合理的。此處是在用反問的語氣引發(fā)讀者思考，即應(yīng)該如何打破慣有的 表揚方式?因此應(yīng)填入含有“方式，模式”意思的名詞，故選I)pattern“模式；圖案”。

33. 答案 D

空格前為不定式符號to, 空格后為介詞短語，因此應(yīng)填入動詞原形。根據(jù)后面提到的“對人 的表揚”和“對過程的表揚”可知，此處是在說明這兩種表揚方式的“不同”,故選 D) distinguish“區(qū)別，辨別”。

34. 答案 N

本句基本成分完整，空格位于is和saying之間，因此應(yīng)填入副詞。此處是對“對人的表揚” 和“對過程的表揚”進行對比，而上一段提到，合理表揚的關(guān)鍵是關(guān)注過程而不是結(jié)果，說明作者更認可“對過程的表揚”,故選N)simply “僅僅”。

35. 答案 O

空格前為助動詞has, 因此應(yīng)填入動詞的-ed 形式?？崭袼诰湟鉃?，對過程的表揚是對某人 剛剛努力的肯定。而努力是人所“做出的”,故選 O)undertaken “著手做，承擔”。

Section B

Directions: In this section,you are going to read a pasage with ten statements aitached to it.Each statement comtains information given in one of the parngraphs.Identify the parngraph 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 corresponding letter on Answer Sheet 2.

Poverty is a story about us,not them

A)Too often still,we think we know what poverty looks like.It's the way weve been taught,the images we've  been force-fed for decades.The chronically homeless.The undocumented immigrant.The urban poor,usually  personified as a woman of color,the“welfare quecn”politicians still too often reference.

B)But as income inequality rises to record levels in the United States,even in the midst of a record economic expansion,those familiar images are outdated,hurttul,and counterproductive to focusing attention on solutions and building ladders of opportunity.

C)Today's faces of income inequality and lack of opportunity look like all of us.It's Anna Landre,a disabled Georgetown University student fighting to keep health benefits that allow her the freedom to  live her life.It's Tiffanie Standard,a counselor for young women of color in Philadelphia who want to be tech entrepreneurs-but who must work multiple jobs to stay afloat.It's Ken Outlaw,a welder in rural North Carolina whose dream of going back to school at a local community college was dashed by Hurricane Florence-just one of the extreme weather events that have tipped the balance for struggling Americans across the nation.

D)If these are the central characters of our story about poverty,what layers of perceptions,myths,and realities must we unearth to find meaningful solutions and support?In pursuit of revealing this complicated reality,Mothering Justice,led by women of color,went last year to the state capital in Lansing,Michigan,to lobby on issues that affect working mothers.One of the Mothering Justice organizers went to the office of a state representative to talk about the lack of affordable childcare-the vestiges (痕跡)of a system that expected mothers to stay home with their children while their husbands worked.A legislative staffer dismissed the activist's concerns,telling her “my husband took care of that—I stayed home.”

E)That comment,says Mothering Justice director Danielle Atkinson,“was meant to shame”and relied on the familiar notion that a woman of color concerned about income inequality and programs that promote mobility must by definition be a single mom,probably with multiple kids.In this case,the Mothering Justice activist happened to be maried.And in most cases in the America of 2019,the images that come to mind when we hear the words poverty or income inequality fail miserably in reflecting a complicated reality:poverty touches virtually all of us.The  face of income inequality,for all but a very few of us,is the one we each see in the mirror.

F)How many of us are poor in the U.S.?It depends on who you ask.According to the Census Bureau, 38 million people in the U.S.are living below the official poverty thresholds.Taking into account economic need beyond that absolute measure,the Institute for Policy Studies found that 140 million people are poor or low-income.That's almost half the U.S.population.

G)Whatever the measure,within that massive group,poverty is extremely diverse.We know that some people  are more affected than others,like children,the elderly,people with disabilities,and people of color.

H）But the fact that 4 in 10 Americans can't come up with S 400 in an emergency is a commonly cited statistic for good reason:economic instability stretches across race,gender,and  geography.It even reaches into the middle classes,as real wages have stagnated (不增長)for all but the very wealthy and temporary spells of financial instability are not uncommon.

I)Negative images remain of who is living in poverty as well as what is needed to move out of it.The big American myth is that you can pull yourself up by your own efforts and change a bad situation into a good  one.The reality is that finding opportunity without help from families,friends,schools,and community is virtually impossible.And the playing field is nothing close to level.

J)The Frame Works Institute,a research group that focuses on public framing of issues,has studied what sustains stereotypes and narratives of poverty in the United Kingdom.“People view economic success and wellbeing in life as a product of choice,willpower,and drive,"says Nat Kendall-Taylor,CEO of FrameWorks.“When we see people who are  struggling,"he says,those assumptions "Iead us to the perception that  people in poverty are lazy,they don't care,and they haven't made the right decisions.”

K)Does this sound familiar?Similar ideas surround poverty in the U.S.And these assumptions give a false picture of reality.“When people enter into that pattern of thinking,”says Kendall-Taylor,“it's cognitively comfortable to make sense of issues of poverty in that way.It creates a kind of cognitive blindness—all of the factors external to a person's drive and choices that they've made become invisible and fade from view.”

L)Those external factors include the difficulties accompanying low-wage work or structural discrimination based on race,gender,or ability.Assumptions get worse when people who are poor use government benefits to help them survive.There is a great tension between“the poor”and those who are receiving what has become a dirty word:“welfare.”

M)According to the General Social Survey,71 percent of respondents believe the country is spending too little on “assistance to the poor.”On the other hand,22 percent think we are spending too little on “welfare”:37 percent believe we are spending too much.

N)“Poverty has been interchangeable with people of color-specifically black women and black mothers,"says  Atkinson of Mothering Justice.It's true that black mothers are more affected by poverty than many other  groups,yet they are disproportionately the face of poverty.For example, Americans routinely overestimate the share of black recipients of public assistance programs.

O)In reality,most people will experience some form of financial hardship at some point in their lives. 

Indeed,people tend to dip in and out of poverty,perhaps due to unexpected obstacles like losing a job,or when hours of a low-wage job fluctuate.

P)Something each of us can do is to treat each other with the dignity and sympathy that is deserved and to understand deeply that the issue of poverty touches all of us.

36.Ome legislative staffer assumed that a woman of color who advocated affordable childcare must be a single mother.

37.People from different raccs,genders,and regions all suffer from a lack of financial security.

38.According to a survey,while the majority believe too little assistance is given to the poor,more than a third believe too much is spent on welfare.

39.A research group has found that Americans who are struggling are thought to be lazy and to have made the wrong decisions.

40.Under the old system in America,a mother was supposed to stay home and take care of her children. 41.It was found that nearly 50%of Americans are poor or receive low pay.

42.Americans usually overestimate the number of blacks receiving welfare benefits.

43.It is impossible for Americans to lift themselves out of poverty entirely on their own.

44.Nowadays,it seems none of us can get away from income inequality.

45.Assumptions about poor people become even more negative when they live on welfare.

Section C

Directions: There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

Passage One

Questions 46 to 50 are basel on the following passage.

Boredom has,paradoxically,become quite interesting to academics lately.In early May,London's Boring Conference celebrated seven years of delighting in dullness.At this event,people flocked to talks about  weather,traffic jams,and vending-machine sounds,among other sleep-inducing topics.

What,exactly,is everybody studying?One widely accepted psychological definition of boredom is “the  distasteful experience of wanting,but being unable,to engage in satisfying activity.”But how can you quantify a person's boredom level and compare it with someone else's?In 1986,psychologists introduced the Boredom Proneness Scale,designed to measure an individual's overall tendency to feel bored.By contrast,the Multidimensional State Boredom Scale,developed in 2008,measures a person's feelings of boredom in a given situation.

Boredom has been linked to behavior issues including inattentive driving,mindless snacking,excessive  drinking,and addictive gambling.In fact,many of us would choose pain over boredom.One team of  psychologists discovered that two-thirds of men and a quarter of women would rather self-administer electrie shocks than sit alone with their thoughts for 15 minutes.Researching this phenomenon,another  team asked volunteers to watch boring,sad,or neutral films,during which they could self-administer  electric shocks.The bored volunteers shocked themselves more and harder than the sad or neutral ones did.

But boredom isn't all bad.By encouraging self-reflection and daydreaming,it can spur creativity.An early study gave participants abundant time to complete problem-solving and word-association exercises.Once all the obvious answers were exhausted,participants gave more and more inventive answers to combat  boredom.A British study took these findings one step further,asking subjects to complete a creative challenge(coming up with a list of alternative uses for a household item).One group of subjects did a boring activity first,while the others went straight to the creative task.Those whose boredom pumps had been primed were more productive.

In our always-connected world,boredom may be a hard-to-define state,but it is a fertile one.Watch  paint dry or water boil,or at least put away your smartphone for a while,and you might unlock your next big idea.

46.When are people likely to experience boredom,according to an accepted psychological definition?

A)When they don't have the chance to do what they want.

B)When they don't enjoy the materials they are studying.

C)When they experience something unpleasant.

D)When they engage in some routine activities.

47.What does the author say boredom can lead to?

A)Determination.

B)Concentration. 

C)Mental deterioration.

D)Harmful conduct.

48.What is the finding of one team of psychologists in their experiment?

A)Volunteers prefer watching a boring movie to sitting alone deliberating.

B)Many volunteers choose to hurt themselves rather than endure boredom.

C)Male volunteers are more immune to the effects of boredom than females.

D)Many volunteers are unable to resist boredom longer than fifteen minutes.

49.Why does the author say boredom isn't all bad?

A)It stimulates memorization.                                  

B)It allows time for relaxation. 

C)It may promote creative thinking.                               

D)It may facilitate independent learning.

Passage Two

Questions 51 to 55 are based on the following passage.

Forests in countries like Brazil and the Congo get a lot of attention from environmentalists,and it is easy to see why.South America and sub-Saharan Africa are experiencing deforestation on an enormous scale:every year almost 5 million hectares are lost.But forests are also changing in rich Western countries.They are growing larger,both in the sense that they occupy more land and that the trees in them are bigger.What is going on?

Forests are spreading in almost all Western countrics,with the fastest growth in places that historically had rather few trees.In 1990 28% of Spain was forested;now the proportion is 37%.In both Greece and  Italy,the growth was from 26% to 32% over the same period.Forests are gradually taking more land in America and Australia.Perhaps most astonishing is the trend in Ireland.Roughly 1% of that country was forested when it became independent in 1922.Now forests cover 11% of the land,and  the government wants to push the proportion to 18% by the 2040s.

Two things are fertilising this growth.The first is the abandonment of farmland,especially in high, dry places where nothing grows terribly well.When farmers give up trying to earn a living from farming or  herding,trees simply move in.The second is government policy and subsidy.Throughout history,governments have protected and promoted forests for diverse reasons,ranging from the need for wooden warships to a  desire to promote suburban house-building.Nowadays forests are increasingly welcome because they suck in  carbon pollution from the air.The justifications change;the desire for more trees remains constant.

The greening of the West does not delight everyone.Farmers complain that land is being taken out of use by generously subsidised tree plantations.Parts of Spain and Portugal suffer from terrible forest fires.  Others simply dislike the appearance of forests planted in neat rows.They will have to get used to the trees,however.The growth of Western forests seems almost as unstoppable as deforestation elsewhere.    

51.What is catching environmentalists'attention nowadays?

A)Rich countries are stripping poor ones of their resources.

B)Forests are fast shrinking in many developing countries.

C)Forests are eating away the fertile farmland worldwide.

D)Rich countries are doing little to address deforestation.

52.Which countries have the fastest forest growth?

A)Those that have newly achieved independence.

B)Those that have the greatest demand for timber.

C)Those that used to have the lowest forest coverage.

D)Those that provide enormous government subsidies.

53.What has encouraged forest growth historically?

A)The government's advocacy.

B)The use of wood for fuel.

C)The favourable climate.

D)The green movement.

54.What accounts for our increasing desire for forests?

A)Their unique scenic beauty.

B)Their use as fruit plantations.

C)Their capability of improving air quality.

D)Their stable supply of building materials.

55.What does the author conclude about the prospects of forestation?

A)Deserts in sub-Saharan Africa will diminish gradually.

B)It will play a more and more important role in people's lives.

C)Forest destruction in the developing world will quickly slow down.

D)Developed and developing countries are moving in opposite directions.

答案解析

51.答案 B

解析：根據(jù)題干關(guān)鍵詞 environmentalists'attention 定位至文章首句。該句提到，巴西和剛果 等國的森林受到了環(huán)保主義者的廣泛關(guān)注，原因很容易理解。隨后進一步指出原因是南美洲和撒哈拉以南的非洲正經(jīng)歷著大規(guī)模的森林砍伐?？芍?，“許多發(fā)展中國家的森 林面積在迅速減少”引起了環(huán)保主義者們的注意，故答案選 B) 項 。

52.答案 C

解析：根據(jù)題干關(guān)鍵詞 fastest forest growth 定位至第二段首句。該句提到，幾乎所有的西方國家的森林都在擴張，在歷史上樹木稀少的地方增長得最快。故答案選 C) 項。

53.答案 A

解析：根據(jù)題干關(guān)鍵詞 encouraged forest growth 定位至第三段首句。該句提到，有兩個因素 在促進這種增長。即放棄農(nóng)田和政府的政策及補貼；第五句中還提到，縱觀歷史，各國 政府都出于各種原因保護和推廣森林的發(fā)展?？芍?ldquo;政府的倡導(dǎo)”促進了歷史上森林 面積的增加，故答案選 A) 項。

54.答案 C
