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 moming 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&39; 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&39;s academic performance, including GPAs.

In the first study， students who stay up late ___________. 查看材料

A.had lower GPAs

B.had higher GPAs

C.performed equally well in their studies

D.had little difficulty concentrating during the day

Reading is not the only way to gain knowledge of the work in the past．There is another largereservoir (知识库) which may be called experience, and the college student will find that everycraftsman (工匠) has something he can teach and will generally teach gladly to any college studentwho does not look down upon them．But the demonstration (示范) and report of what happens,and how it happens are correct even if the reports are in completely unscientific terms (术语)．Presently the college student will learn, in this case also, what to accept and what to reject．

Another source of knowledge is the vast store of traditional practices handed down from fatherto son, or mother to daughter, of old country customs, of folklore (风俗)．All this is very diffi-cult for a college student to examine, for much knowledge and personal experience is needed hereto separate good plants from wild grass．The college student should learn to realize and rememberhow much of real value science has found in this wide, confused wilderness．

In the last paragraph the phrase "this wide， confused wilderness" refers to __________．查看材料

Sleeplessness

Insomnia or sleeplessness is a common complaint of women as they enter into menopause. Insomnia means having trouble falliig asleep or staying asleep or the feeling that your sleep was not adequate for you. For women who are having night sweats, their sleep is broken by frequent a-wakening and therefore not refreshing. Generally once the night sweats are controlled a normal sleep pattern returns. If it doesn&39;t it may be, or have become chronic insomnia. How do you know？

If you suffer from insomnia every night or most nights for a period of one month then you have chronic insomnia. If you&39;re not having night sweats then it&39;s time to look for other causes of sleeplessness. Depression and anxiety disorders are the most common causes of chronic insomnia.

If you feel depressed you need to be checked by a qualified health care provider. Movement disorders such as restless leg syndrome are second on the list of insomnia for them, there are new medicines that may help. Other common causes are shift working, and pain.

In up to 30% of people with chronic insomnia no cause can be identified. Medical treatment of these people has generally been with sleeping pills. It is estimated that 25% of the adult population in America took some type of medicines for sleep last year. It is generally agreed that sleep- ing pills should only be in the lowest dose and for the shortest possible time.

Sleep hygiene is directed at changing bad sleep habits. The recommendations are: -Go to bed only when sleepy.Do not wait up to a specified time. -Avoid caffeine and alcohol in the evening, etc.

根据以下内容回答题:

Happiness can be described as a positive mood and a pleasant state of mind． According to recent polls sixty to seventy percent of Americans consider themselves to be moderately happy and one in twenty persons feels very unhappy．Psychologists have been study-ing the factors that contribute to happiness．It is not predictable nor is a person in an apparently ideal situation necessarily happy．The ideal situation may have little to do with his actual feel-ings． A good education and income are usually considered necessary for happiness．Though both may contribute，they are only chief factors if the person is seriously under-educated or actually suffering from lack of physical needs． The rich are not likely to be happier than the middle-income group or even those with very low incomes．People with college educations are somewhat happier than those who did not gra-duate from high school，and it is believed that this is mainly because they have more opportuni-ty to control their lives．Yet people with a high income and a college education may be less happy than those with the same income and no college education． Poor health does not rule out happiness except for the severely debilitated or those in pain．Learning to cope with a health problem can contribute to happiness．Those with a good sex lifeare happier in general，but those who have a loving affectionate relationship are happier than those who rely on sex alone．Love has a higher correlation with happiness than any other factor． It should be noted that people quickly get used to what they have，and they are happiest when they feel they are increasing their level no matter where it stands at a given time． Children whose parents were happily married have happier childhoods but are not nece—ssarily happier adults． The best formula for happiness is to be able to develop the ability to tolerate frustration，to have a personal involvement and commitment，and to develop self-confidence and self-esteem．

According to the article，happiness is greatly dependent upon（）．

A.happy childhood

B.great wealth

C.a feeling that conditions are improving over what they were

D.a college degree
