题目内容
9．High school in the United States starts too early．Given teenagers'sleep patterns，the ideal school start time could be as late as 11：30 a．m．-when many high school students have already finished half a school day and are eating lunch．Researchers from Harvard and Oxford wrote about this new finding in a recent article in the journal Learning，Media，and Technology．In the article，Paul Kelley argued that，given when kids and teenagers are biologically conditioned to wake up，10-year-olds should start school at 8 a．m．，16-year-olds should start between 10 a．m．and 10：30 a．m．，and 18-year-olds should start between 11 a．m．and 11：30 a．m．
There's been lots of research done on sleep and performance in school-but this article argues that school should start even later than most proposals for a later start time call for．Teens aren't lazy-adults need to adjust．This isn't laziness-sleep patterns are a biological necessity．Reviewi ng evidence from studies around the world，the researchers argue that starting school later would help students learn more，perform better on tests，and even make teenagers less annoyed．When the Minneapolis Public Schools moved their start time from 7：15 a．m．to 8：40 a．m．，students liked the change and reported that"attendance，achievement，behavior，and mood improved．"
Parents were positive，too.92 percent said they liked the change，and parents reported that their kids were easier to live with when they weren't getting up so early．At the US Air Force Academy，where students were randomly assigned（分配；指派）to classes with earlier and later start times，students who started earlier performed worse all day long on those days．
The researchers argue that this is partly cultural，and that getting up early is still seen as a virtue．That's wrong，They write："A common belief is that adolescents are tired because they choose to stay up too late，or are difficult to wake in the morning because they are lazy．Educators tend to think that adolescents learn best in the morning and if they simply went to sleep earlier，it would improve their concentration．The truth is that adults need to be educated．"

解答 61-65．ABDCD
61题答案：A考查主旨大意，本文主要讨论的是高中学校的上课时间太早使学生得不到足够的睡眠、学校表现差；因此研究者建议要推迟上课的时间．故本题答案为A选项．
62题答案：B考查细节推理，根据文章第二段的In the article，Paul Kelley argued that，given when kids and teenagers are biologically conditioned to wake up，10-year-olds should start school at 8 a．m．，16-year-olds should start between 10 a．m．and 10：30 a．m．，and 18-year-olds should start between 11 a．m．and 11：30 a．m．在该文章中，Paul Kelley辩论考虑到孩子和青少年生理上适合醒来的时间，十岁的孩子应该8点上课，十六岁的应该在十点和十点半之间上课，18岁的应该在十一点和十一点半开始上课．可知本题答案为B选项．
63题答案：D考查细节推理，根据第三段的…starting school later would help students learn more，perform better on tests，and even make teenagers less annoyed．（上学晚点会帮助学生学得更多、考试表现更好、甚至使青少年不那么不开心）．可知D选项并未提及（根据常识也知道D选项错误），故本题答案为D选项．
64题答案：C考查细节推理，根据倒数第二段的Parents were positive，too.92 percent said they liked the change，and parents reported that their kids were easier to live with when they weren't getting up so early．父母是积极的，92%的家长说他们喜欢改变，而且父母说他们的孩子起床不这么早后更容易相处了．可知本题答案为C选项．
65题答案：D考查细节推理，根据文章倒数第二段的…students who started earlier performed worse all day long on those days．上学时间更早的学生在那些日子里（试验的日子里）整天都表现更差．可知为了表现良好，需要培养良好的早睡习惯；故本题答案为D选项．
