第一篇College Night Owls Have Lower GradesCollege 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(大学本科生的) 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 (专业的) 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.I 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." 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

案例分析题案例一：TCL 王牌彩电逐鹿中原请多名当代著名影视明星作广告模特的 TCL 王牌大屏幕彩电一跃成为国产大屏幕彩电销售之冠，中国惠州的 TCL 成为同行中杀出的一匹黑马。中原，这一古往今来的兵家必争之地，也是近年来闻名全国的商战舞台。1995 年，TCL 成功地进入了中原市场。据郑州五大商场大屏幕彩电销售统计，第一季度，进口彩电零售 1000 余台，国产品牌不到 40 台；第二季度，TCL 销售了 1000 余台，其他国产品牌 200 余台，而进口品牌不到 150 台。TCL 到底是如何攻占中原市场的呢？ 1．媒体公关。1995 年 3 月，正值彩电销售的淡季，许多厂家都在修生养息，TCL 却在为进军郑州市场做准备。一个由河南电视台、河南日报、河南电视广播、郑州晚报等 10 家新闻单位代表组成的考察采访团，被请到了 TCL 集团所在地惠州。他们采访、考察了 TCL 集团彩电生产情况，看到了 TCL 科学严格的管理制度。后来又与惠州市政府、广东新闻界开座谈会。左右着河南舆论的河南新闻界，已从内心感到 TCL 王牌不久将成为中原市场的王牌了。 2．抢占零售制高点。将 TCL 切入郑州彩电销售的 8 大商场，名曰“名品进名店”。在和 8 大商场合作谈判时，该厂坚持要布置 TCL王牌的红色展柜和设立独立于家电联保之外的售后服务中心。这和其他彩电厂家有着明显的不同，该厂可以统一展柜的硬件，保持统一的服务水准和采用自己的促销手段。 3．造声势。有序地在郑州几大媒体作广告宣传。如在《郑州晚报》刊出的“TCL 王牌彩电为何魅力无穷”的广告称：“现售开箱合格率99.8%，现售换机返修率为 0.8%。” 4．给消费者吃定心丸。TCL 提出了”60 天内保换，3 年保修，终生维修，免收服务费”的售后服务承诺。每次广告中都要公布售后服务电话号码和传呼机号。该厂和质量时报、郑州消费者协会、金水区技术监督局合作，作了一次详细的用户调查，并把调查结果公之于众。结果 90%的用户认为， TCL 服务时间快；92%的人认为 TCL 的服务技术高。从 4 月 13 日到 6 月 24 日，仅是郑州几大商场销售的 TCL 大屏幕彩电已近 3000 台。7 月，郑州分公司汇款额在集团公司 26 家分公司中名列第七，8 月上升到第 2 位。TCL 王牌大屏幕彩电在郑州地区市场占有率一直保持在 40%左右，个别大屏幕机型占有率达 65%，名列第一。问题： TCL 请慕名影视明星或名人做广告模特或广告代言人，试分析名人广告的利弊。
