2、 disease.Now，a new study has found that getting sufficient sleep is also the key to improving academic performance.Jeffrey Gross，the university science professor who led the research，was not trying to find the relationship between sleep and grades when he handed out smartwatches to the 100 students
3、in his chemistry class.Instead，the professor hoped the wristworn devices，which track a persons physical activity，would show a connection between exercise and academic achievements.While Grosss data showed no relationship between these two factors，the study found something surprising.As the researche
4、rs were analyzing their data，they noticed that there was a linear(线性的) relationship between the average amount of sleep the students got and their results in the courses 11 quizzes，three midterm tests，and the final exam.Even more interesting，it was not sufficient for students to just head to bed ear
5、ly the night before a test.Instead，its the sleep you get during the days when learning is happening that matters most.When students went to bed each night was similarly important.Those who went to bed in the early hours of the morning performed poorly，even if the total sleep time was the same as a h
6、igherperforming student.“When you go to bed matters，” Gross says.“If you go to bed at 10，or 12，or 1 at night，and sleep for seven hours，your performance is the same.But if you go to bed after 2，your performance starts to go down even if you get the same seven hours sleep.So，quantity isnt everything.”
7、Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students grades.The overall course grades of students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep.Similarly，students who vari
8、ed their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtime.Who knew getting straight As just required some extra sleep?【语篇解读】一项新的研究发现，每天在恰当的时间段内进行充足的睡眠是提高学业成绩的关键。1Based on his original objective，which best describes Professor Grosss research findin
9、gs?AAccidental.BComplete.CConvincing.DDoubtful.A细节理解题。根据第二段的内容以及第三段第一句“While Grosss data showed no relationship between these two factors，the study found something surprising”可知，Gross给自己班里的100名学生分发智能手表是打算研究运动与学业成绩之间的联系，但是Gross搜集到的数据没有表明二者之间的联系，不过该研究有意外的发现。故选A。2Who were the people taking part in the
10、study?AMiddle school chemistry students.BVolunteers from different universities.CProfessor Grosss own students.DUniversity student athletes.C细节理解题。根据第二段第一句中的“he handed out smartwatches to the 100 students in his chemistry class”可知，参加研究的是Gross自己的学生。故选C。3How did Professor Grosss team measure students

12、1 quizzes, three midterm tests，and the final exam”可知，当研究人员分析他们的数据时，他们注意到学生的平均睡眠时间与他们在这门课的11次小测验、3次期中考试和期末考试中的成绩之间存在线性关系。由此可知，Gross教授的团队是使用学生平常的测试与小测验成绩来衡量学生的学业表现的。故选D。4Based on the studys findings，who is likely to perform best academically?AA student who has a good nights sleep the night before an i
13、mportant test.BA student whose normal bedtime varies between 9 pm.and 12 pm.CA student who sleeps from 11 pm.to 6 am.each day.DA student who sleeps for a total of 7 hours each night.C推理判断题。根据第五段的内容可知，什么时候去睡觉很重要，如果你晚上10点、12点或1点睡觉，睡7个小时，你的表现是一样的；但是如果你在2点以后睡觉，即使你同样睡了7个小时，你的表现也会开始下降。且根据第六段最后一句可知，有规律的就寝时
14、间也很重要。由此可推知，每天从晚上11点睡到早上6点的学生，其学业表现可能最好。故选C。【干扰项分析】根据第四段第一句中的“it was not sufficient.before a test”可知，A项错误。B(2020山东省一模)Heads up!

37、 and clinicians Ive interviewed over the years，is that obesity is caused by extra calories.They refer to it as an “energy balance” disorder，and so the treatment is to consume less energy (fewer calories) and expend more.When we fail to maintain this goal，the implication is that we simply lack willpo
38、wer or self discipline.The minoritys position in this field one that Dr.Ludwig holds，as do I after years of reporting is that obesity is actually a hormonal regulatory disorder，and the hormone (激素) that dominates this process is insulin(胰岛素)It directly links what we eat to the accumulation of extra
39、fat and that，in turn，is tied to the foods we long for and the hunger we experience.Its been known since the 1960s that insulin signals fat cells to accumulate fat，while telling the other cells in our body to burn carbohydrates (碳水化合物) for fuel.If you promote insulin levels even a little，says Dr.Robe

44、imply lack willpower or selfdiscipline”可知，传统的观念认为，当我们不能保持吃得少且消耗得多这个目标时，就意味着我们缺乏意志力或自律能力。由此可知，传统观念将人们的能量不均衡归结于心理方面的因素。故选A。2What does the author think leads to obesity?ASurplus calories.BHigh insulin levels.CLack of exercise.DLow hormone levels.B细节理解题。根据第三段第一句中的“one that Dr.Ludwig holds，as do I after
45、years of reportingis that obesity is actually a hormonal regulatory disorder，and the hormone(激素)that dominates this process is insulin(胰岛素)”以及第五段第一句中的“The more insulin you release，the more you need carbs”可知，作者认为肥胖实际上是一种激素调节紊乱，主导这一过程的激素是胰岛素，并且释放的胰岛素越多，人体就越需要碳水化合物，这样就会让肥胖的可能性增加。故选B。3According to Dr.Lu

48、rgy(fewer calories)and expend more”和第三句话的内容以及第六段Dr.Lustig所说的“And if they fall off the wagon and start eating carbs，they go right back to where they were before”可推知，在对抗肥胖症的过程中，两种观念都主张选择一种不会引起肥胖的饮食结构，并坚持下去。故选C。B(2020云南省高中毕业生复习统一检测)Pang Hui placed a few more pairs of chopsticks on the table for a famil
