120 degrees Fahrenheit.Butfor the Saharan silver ant,26 from their underground nests into the sun's brutal rays to 27 forfood,this is the perfect time to seek lunch.In 2015 these ants were joined in

heat that can 30 meltthe bottom of shoes.Back in Belgium,the scientists looked at the ants under an electronic microscope and found that their31,triangular hair reflects light like a prism ()giving

questions by marking the corresponding letter on Answer Sheet 2.The start of high school doesn't have to be stressfulA)This month,more than 4 million students across the nation will begin high school.Many 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.Some 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.Ultimately it should matter tothe students themselves and society at large,because students'experience of transitioning (tothe ninth grade can have long-term consequences not only for the students themselves but for theirhome communities.We make these observations as research psychologists who have 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 to the local economy for a single additional student who completeshigh school is half a million 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 students'ability 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 one month to thenext,signaling striking instability in friendships.E)In addition,studies find the first year of high school 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 academic demands are rising.Furthermore,most adult cases of clinical depressionfirst emerge in adolescence ()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 that's riding 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:Students'beliefs about change-their beliefs about whetherpeople are stuck one way forever,or whether people can change their personalities and abilities-are四级2021年6月4related to their ability to cope,succeed academically and maintain good mental health.Past researchhas called these beliefs“mindsets(思维模式)，”with a“fixed mindset'”referring to the belief thatpeople cannot 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 "smartness"-that is,their fixed mindsets about intelligence.We then assessed biological stress responses for students whosegrades were dropping by examining their stress hormones ()Students who believed thatintelligence is fixed-that you are stuck being "not smart"if you struggle in school-showed higherlevels of stress hormones when their grades were declining at the beginning of the ninth grade.Ifstudents believed that intelligence could improve-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 body's stress responses are notdetermined solely by one's grades.Instead,declining grades only 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 their social standing-that is,whetherthey are bullied or excluded or left out-can change over time.We then looked at high school students'stress responses to daily social difficulties.That is,we taught them a growth mindset about their sociallives.In this study,students came into the laboratory and 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 not 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 worse 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 (showed less-contracted blood vessels and their heartspumped more blood-both 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 (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 their 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 experiencing 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 mindset.39.According to one study,each high school graduate contributes at least 500,000 dollars to the localeconomy.四级2021年6月5
