　　第二篇    Shopping at Second-hand Clothing Stores

　　When 33-year-old Pete Barth was in college，shopping at second-hand clothing　stores was just something he did - “like changing the tires on his car.” He looked at his budget and decided he could save a lot of money by shopping for clothes at thrift shops.

　　“Even new clothes are fairly disposable （可丢掉的）and wear out after a couple of years，” Barth said. “In thrift shops，you can find some great stuff whose quality is better than new clothes.”

　　Since then，Barth，who works at a Goodwill thrift shop in the US state of Florida，has found that there are all kinds of reasons for shopping for second-hand clothing. Some people，like him，shop to save money. Some shop for a crazy-looking shirt. And some shop as a means of conserving energy and helping the environment.

　　Pat Akins，an accountant at a Florida Salvation Army （SA）（救世军）thrift shop，said that，for her，shopping at thrift shops is a way to help the environment.

　　“When my daughter was little，we looked at it as recycling，” Akins said. “Also，why pay 30 dollars for a new coat when you can get another one for a lot less？”

　　Akins said that the SA has shops all over the US - “some as big as department　stores.” All of the clothes are donated （捐赠），and when they have a surplus （盈余），they'll have “stuff a bag” specials，where customers can fill a grocery sack With clothes for only 5 or 10 dollars.

　　Julia Slocum，22，points out，however，that the huge amount of second-hand clothing in the US is the result of American wastefulness.

　　I'd say that second-hand stores are the result of our wasteful，materialistic culture，“ said Slocum，who works for a pro-conservation organization，the Center for a New American Dream. ”Thrift shops prevent that waste from going to landfills （垃圾填埋场）； they give clothing a second life，provide cheaper clothing for those who can't afford new ones and generate （生成）income for charities. They also provide a way for the wealthy and middle classes to shed （摆脱）some of the guilt for their level of consumption.“

　　A　to save money.

　　38 What does Akins do？

　　第三篇    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（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 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 impac
