But for the Saharan silver ant, 26 from their underground nests into the suns brutal rays to 27 for food, this is the perfect time ,to seek lunch. In 2015 these ants

24、 were joined in the desert by scientists from two Belgian universities, who spent a month in the 28 heat tracking the ants and digging out their nests. Toe goal was simple, to discover how theadapted to the kind of heat that can 30 melt the bottom of shoes. Back in Belgium, the scientists looked at

25、the ants under an electronic microscope and found that their 31 , triangular hair reflects light like a prism (棱镜），giving them a metallic reflection and protecting them from the suns aw血heat.

28、t contains information given in one of the paragrap加. Identify the paragraph from which the information is derived. You may choo犯a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2. The start of high school do

29、esnt have to be stressful A) This month, more than 4 million students across the nation will begin high school. M皿y will do well.But many will not. Consider that nearly two-thirds of students will experience the ninth-gradeshock, which refers to a dramatic drop in a student s academic performance. S

30、ome students cope withthis shock by avoiding challenges. For instance, they may drop difficult coursework. Others mayexperience a hopelessness that results in failing their core classes, such as English, science and math.B) This should matter a great deal to parents, teachers and policymakers. Ultim

31、ately it should matter tothe students themselves and society at large, because studentsexperience of transitioning (过渡） tothe ninth grade can have long.:term consequences not only for the students themselves but for theirhome communities. We m吐e these observations as research psychologists who have

32、studied howschools and families can help young people thrive.C) In the new global economy, students who fail to finish the ninth grade with passing grades in collegepreparatory coursework are very unlikely to graduate on time and ,go on to get jobs. One study hascalculated that the lifetime benefit

33、to the local economy for a single additional student who completeshigh school is half a m诅ion dollars or more. This is based on higher earnings and avoided costs inhealth care, crime, welfare dependence and other things.D) The consequences of doing poorly in the ninth grade can impact more than stud

34、entsability to find agood job. It can also impact the extent to which they enjoy life. Students lose many of the friends theyturned to for support when they move from the eighth to the ninth grade. One study of ninth-gradestudents found that 50 percent of friendships among ninth graders changed from

35、 one month to thenext, signaling striking instability in friendships.E) In addition, studies find the first year of high妃hool typically shows one of the greatest increases indepression of any year over the lifespan. Researchers think that one explanation is that ties to friendsare broken while acade

36、mic demands are rising. Furthermore, most adult cases of clinical depressionfirst emerge in adolescence (青春期）. The World Health Organization reports that depression has thegreatest burden of disease worldwide, in terms of the total cost of treatment and the loss ofproductivity.F) Given all thats rid

37、ing on having a successful ninth grade experience, it pays to explore what: can bedone to meet the academic, social and emotional challenges of the transition to high school. So far,our studies have yielded one main insight: Studentsbeliefs about change-their beliefs about whetherpeople are stuck on

38、e way forever, or whether people can change their personalities and abilities-are四级2021年6月4 related to their ability to cope, succeed academically and maintain good mental health. Past research has called these beliefs mindsets (思维模式）， with a fixed mindset referring to the belief that people cannot

39、change and a growth mindset referring to the belief that people can change. G) In one recent study, we examined 360 adolescents beliefs about the nature of smartnessthat is,their fixed mindsets about intelligence. We then assessed biological stress responses for students whosegrades were dropping by

40、 examining their stress加rmones (荷尔蒙）. Students who believed thatintelligence is fixedthat you are stuck being not smart if you struggle in schoolshowed higherlevels of stress hormones when their grades were declining at the beginning of the ninth grade. Ifstudents believed that intelligence could im

41、prove-that is to say, when they held more of a growthmindset of intelligence-they showed lower levels of stress hormones when their grades weredeclining. This was an exciting result because it showed that the bodys stress responses are notdetermined solely by ones grades. Instead, declining grades o

42、nly predicted worse stress hormonesamong students who believed that worsening grades were a permanent and hopeless state of affairs.H) We also investigated the social side of the high school transition. In this study, instead of teachingstudents that their smartness can change, we taught them that t

43、heir social standingthat is, whetherthey are bullied or excluded or left out一can change over time. We then looked at high school studentsstress responses to daily social difficulties. That is, we taught them a growth mindset about their sociallives. In this study, students came into the laboratory a

44、nd were asked to give a public speech in front ofupper-year students. The topic of the speech was what makes one popular in high school. Followingthis, students had to complete a difficult mental math task in front of the same upper-year students.I) Experiment results showed that students who were n

45、ot taught that people can change showed poorstress responses. When these students gave the speech, their blood vessels contracted and their heartspumped less blood through the body-both responses that the body shows when it is preparing fordamage or defeat after a physical threat. Then they gave wor

46、se speeches and made more mistakes inmath. But when students were taught that people can change, they had better responses to stress, inpart because they felt like they had the resources to deal with the demanding situation. Students whogot the growth mindset intervention (干预） showed less-contracted

47、 blood vessels and their heartspumped more bloodboth of which contributed to more oxygen getting to the brain, and, ultimately,better performance on the speech and mental math tasks.J) These findings lead to several possibilities that we are investigating further. First, we are working toreplicate (

48、复制） these findings in more diverse school communities. We want to know in which typesof schools and for which kinds of students these growth mindset ideas help young people adapt to thechallenges of high school. We also hope to learn how teachers, parents or school counselors can helpstudents keep t

49、heir ongoing academic or social difficulties in perspective. We wonder what wouldhappen if schools helped to make beliefs about the potential for change and improvement a largerfeature of the overall school culture, especially for students starting the ninth grade.36. The number of people experienci

50、ng depression shows a sharp increase in the first year of high school.37. According to one study, students academic performance is not the only decisive factor of their stressresponses.38. Researchers would like to explore further how parents and schools can help ninth graders by changingtheir minds
