College Night Owls Have Lower Grades
College students who are morning people tend to get better grades than those who are night owls (晚睡的人), according to University of North Texas researchers.
They had 824 undergraduate students complete a health survey that included questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages(GPAs) than those who are night people.
"The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co-author Daniel J. Taylor said in a prepared statement.
"Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types." Taylor said.
The research was expected to be presented Monday at sleep, the annual meeting of the Associated Professional Sleep Societies, in Baltimore.
In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia(失眠) and a decline in college students" academic performance.
The study included 64 psychology, nursing and medical students, average age 27.4 years, who were divided into two groups—low GPAs and high GPAs.
Among those with low GPAs, 69.7 percent had trouble falling asleep, 53.1 percent experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day.
"In college students, the complaint of difficulty concentrating during the day Continues to have a considerable impact on their ability to succeed in the classroom," study author Dr James F. Pagel said in a prepared statement, "This study showed that disordered sleep has significant harmful effects on a student"s academic performance, including GPAs."
单选题 In the first study, students who stay up late ______.
【正确答案】 A
【答案解析】[解析] 本题问的是第一项研究表明了熬夜的学生的什么信息。原文第二段的最后面提到，…found that students who are morning people had higher grade point averages (GPAs)than those who are night people. 说明早起的学生比熬夜的学生的平均积分点高。且第三段的第一句话也明确说到，The finding that college students who are evening types have lower GPAs is a very important finding…说明熬夜学生的平均积分点更低。因此，本题的正确答案为A。
单选题 Mr. Taylor believed that the finding of their study would soon ______.
【正确答案】 C
【答案解析】[解析] 本题问的是Mr. Taylor认为这个研究的结果会怎样。原文第三段是Mr. Taylor所说的话，其中提到，The finding…sure to make its way into undergraduate psychology texts in the near future, …由此可知，Mr. Taylor认为这项研究结果将会很快被收录到在校本科生心理学的课本中。因此，本题的正确答案为C。
单选题 The passage indicates that chronotherapy can be used to help people to ______.
【正确答案】 D
【答案解析】[解析] 本题问的是本文所暗示的时间疗法(chronotherapy)的作用。原文的第四段明确说到，…using chronotherapy to help students retrain their biological clock to become more morning types. 由此可知，时间疗法可以帮助重新调整人的生物钟。因此，本题的正确答案为D。
单选题 In the second study, students with low GPAs did NOT complain of ______.
【正确答案】 D
【答案解析】[解析] 本题问的是第二项研究表明平均积分点低的学生没有抱怨什么。原文的倒数第二段表明，在这些分数低的学生中，69.7%的人很难入睡，53.1%的人夜里会踢腿或痉挛，65.6%的人夜里会醒来并很难再入睡，72.7%的人白天无法集中精神。由此可知，A、B、C三个选项都是原文中提到的低分数学生的表现，只有D选项“夜里他们的腿被踢”没有提到，注意不要与原文中的“踢腿”混淆。因此，本题的正确答案为D。
单选题 According to Dr. Pagel, the academic performance of a student will be affected ______.
【正确答案】 B
【答案解析】[解析] 本题问的是Dr. Page1认为学生的学业成绩会受到什么影响。原文的最后一段介绍的是Dr. Page1的观点。该段的最后一句话明确说到，This study showed that disordered sleep has significant harmful effects on a student"s academic performance, including GPAs. 由此可知，睡眠紊乱会严重影响学生的学业成绩。因此，本题的正确答案为B。
