College Night Owls（晚睡的人）Have Lower Grades

College students who are morning people tend to get better grades than those who are night owls,
according to University of North Texas researchers.
They had 824 undergraduate（大学本科生的）students complete a health survey that included questiom
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 retrieve their biological clock to become 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一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."

选项 In the first study,students who stay up late________. A:had lower GPAs B:had higher GPAs C:performed equally well in their studies D:had little difficulty concentrating during the day

答案 A

解析由文章第二段中“students who are morning people had higher grade point averages (GPAs) than those who are night people”可知，第一个研究中显示，早起的学生比晚睡的学生的年级平均成绩（GPAs）要高，这里的night people即“students who stay up late"，故选A。
由文章第三段中Daniel J.Taylor的话“The finding...sure to make its way into undergraduate psychology texts in the near future”可知，Taylor先生相信他们的研究结果意义重大，肯定会成为将来本科生的心理学教材内容，故选C。
由文章第四段中Taylor的话“these results suggest...by using chronotherapy to help students retrieve their biological clock...”可知，可以通过时间疗法来帮助学生调整生物钟，重新成为早起型的学生，以改善其学习表现，故选D。
由文章最后两段的内容可知，A、B、C三项的内容均是第二份研究中年级平均成绩低的学生抱怨的内容，D项的“being kicked in the leg at night”意思是“夜里被踢到腿”，而倒数第二段中的“leg kicks”指的是踢腿（即睡觉时多动），故选D。
由文章最后一段的最后一句话可知，睡眠不正常对学生的学业（年级平均成绩）表现产生很大的不良影响，故选B。第5部分：补全短文
