(2015·宿迁市三模)Depression can be a devastating illness，plaguingmillions of people worldwide with feelings of sadness，hopelessness，andfatigue.Despite numerous antidepressant drugs，as many as a third ofpatients don’t respond to medication.This has forced doctors to be morecreative in finding different treatments for the condition.

In the past two decades，researchers have tied depression to aseemingly unrelated condition：inflammation(炎症)，the body’s naturalresponse to stress.It could rise from injury or inflection，or even emotionalissues like an unhappy marriage or problems at work.Some amount ofinflammation is generally beneficial，as it increases production of cytokines(致癌因子)，proteins that help us heal and protect us from the effects ofoverwork.

But excessive cytokine levels，and the inflammation they bring on，could come at a cost.A number of studies suggest that high levels ofcytokines could contribute to depression.

Cytokines can reach the brain several ways：directly through theblood​brain barrier or indirectly by binding to nerve fibers elsewhere，whichsend signals to the brain to produce the inflammation molecules.In thebrain，cytokines can disturb the production and release of several importantsignaling chemicals，including serotonin，dopamine and glutamate，whichhelp control emotion，appetite，sleep，learning and memory.It’s thoughtthat a lack of serotonin activity in the brain causes depression; mostantidepressants increase the activity.But cytokines also have been shown toactivate stress hormone signaling in the brain，which can also serve todevelop depression.

With all the evidence implicating inflammation in depression，doctors have been anxious to test anti​inflammatory drugs as a potential

treatment.Four small students published between 2006 and 2012 by researchgroups in Europe and Iran found that adults diagnosed with depression whotook aspirin or another anti​inflammatory drug called C elecoxib，along withan antidepressant，got more relief from feelings of sadness，hopelessness，guilt and fatigue compared with those taking an antidepressant

alone.However，Andrew Miller，a professor of psychiatry at EmoryUniversity，thought something was amiss in these small，limitedstudies.None of them looked at whether the participants had to have highlevels of cytokines before into the trap of viewing inflammatorydrugs.“Unfortunately，much of the field has fallen into the trap of viewinginflammation as the be​all，end​all，” Miller says.He and his colleagueswanted to see whether the effect of these drugs was limited to the depressionpatients with high cytokine levels，or if it helped all people diagnosed withdepression.

(2016·贵州七校联盟第一次联考)The largest land animal remaining onthe earth，the African elephant，is of much importance to African

ecosystem.Unlike other animals，the African elephant is to a great extent the builder of its environment.As a giant plant​eater，it significantly shapes the forest​and​savanna surroundings in which it lives，therefore deciding the conditions of existence for millions of other animals that live in its habitat.

It is the elephant’s great desire for food that makes it both a disturber ofthe environment and an important builder of its habitat.In its continuoussearch for the 300 pounds of plants it must have every day，it kills smalltrees and bushes，as well as pulls branches off big trees.This results innumerous open spaces in not only deep tropical forests but also thewoodlands that cover part of the African savannas.In these open spaces，there are numerous plants in various stages of growth，which attract avariety of other plant​eaters.

Take the rain forests for example.In their natural states，the spreadingbranches overhead shut out sunlight and prevent the growth of plants on theforest floor.By pulling down trees and eating plants，elephants create openspaces，allowing new plants to grow on the forest floor.In such situations，the forests become suitable for large​hoofed plant​eaters to move around andfor small​sized plant​eaters to obtain their food as well.

Scientists are worried now that the African elephant has become anendangered species.If the elephant dies out，scientists say，many other animals will also disappear from vast areas of forests and savannas，greatly changing and worsening the whole ecosystem.

(2015·高考命题专家原创卷)You signed up for soccer，and playedevery game of the season.Sure，you’re not the best player on the team，butmost days you gave it your all.Do you deserve a trophy(奖杯)?

If the decision is up to Carol Dweck，the answer would likely beno.She’s a psychology professor at Stanford University，California.She saysa player doesn’t have to be the best to get a trophy.But those who receive anaward should have to work for it.She suggests trophies go to the mostimproved player，or the one who contributed most to the team spirit，aswell as to those who play the best.

“The trophy has to stand for something，”Dweck told TFK.“If we givea trophy to everyone，then the award has no value.”Dweck argues thatgiving kids trophies for particular reasons，such as improving in a sport，teaches kids that adults value hard work and trying our best.

Others say that there’s no harm in giving awards to all kids who play asport，regardless of how they played or whether or not they improved.

“I think we should encourage kids’ participation in sports，” saysKenneth Barish，a psychology professor at Weill Cornell Medical College，in New York City.“A trophy is one way to encourage kids’ efforts.”

Barish argues that when we single_out only the best or even the mostimproved players with a trophy，we are teaching kids the wrong lesson.Weare sending the message that winning is everything.“Winning is only part ofthe equation(等式)，” Barish told TFK.“Playing sports also teaches kidsabout teamwork and the importance of exercise.”

There will be plenty of opportunity for kids to learn about competitionas they get older，says Barish.They’ll soon realize that only one soccer teamwins the World Cup and only one football team wins the Super Bowl.Fornow，he thinks there’s nothing wrong with letting all kids who play a sportfeel like winners.That means trophies for everyone.

【解题导语】　如果孩子参加体育比赛，那么是不是每个人都该得到奖杯呢？文章就这个问题给出了两种不同的看法。

9．According to Carol Dweck，which player should receive a trophy?A．Tony，the most attractive player of the soccer team.B．David，a soccer player who is both clever and funny.C．Peter，who is ready to help his partners to score goals.D．Jim，a soccer player who tries his best to win the game.

解析：选C。推理判断题。根据第二段可知，斯坦福大学的心理学教授Carol Dweck认为，获奖的运动员未必是最好的运动员。她认为，进步最大的、对团队精神贡献最多的和表现最佳的运动员都应获奖。故C项正确。

10．Which of the following statements would Kenneth Barish agreewith?

A．There is no sense in giving a trophy to everyone.B．Kids fond of playing sports should be rewarded.C．Kids should be given trophies for trying their best.

D．It is necessary to encourage kids’ participation in sports.

解析：选D。细节理解题。根据第五段可知，纽约市威尔康乃尔医

学院心理学教授Kenneth Barish认为，我们应该鼓励孩子参加体育活动。颁发奖杯是一种激励方式。

11．The underlined phrase“single out” in Paragraph 6 probablymeans“________”．

A．honour　　　　　　　 B．chooseC．value D．stress

解析：选B。词义猜测题。根据第六段可知，Barish认为，当我们挑选出最佳球员或进步最大球员并授予他们奖杯的时候，我们给孩子传递了一个错误的信号：获胜就是一切。因此画线的短语“single out”意为“挑出”。

12．Which shows the correct structure of the text?

解析：选B。篇章结构题。本文的第一段为导语，导入讨论的话题。第二、三段陈述了斯坦福大学的心理学教授Carol Dweck的主要观点：反对人人获奖。下文(第四段至第七段)陈述的是纽约市威尔康乃尔医学院的心理学教授Kenneth Barish的观点，即赞成人人获奖。因此B项清晰地展示了本文的结构。
