First,the amount of alcohol in 27 different popular energy drinks was measured.All but one had an alcohol level greater than 0.005%.In nine of the 27 drinks,the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT.They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27 energy drinks,the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken.However,alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed.This shows that when the test is taken plays an important role in the test result.The sooner the test is conducted after the consumption of these drinks,the more likely a positive alcohol reading will be obtained.

This was not the first time I’d heard such a statement,but with graduation fast coming close,her words especially struck me.It seemed a bit disappointing to reach one’s life peak at only 22 years of age,but in her opinion,college had been one of the best times in my life so far.I made friends,took classes,and learned a great deal about myself.But I was also excited for the time after college—moving to a new city,starting a new job,and becoming a “real” person.I hoped that my great dreams were practical.
Then,last week I read a column in Real Simple Magazine called 100 Years of Attitude,in which women 100 years or older shared their life experiences and views.I noticed that none of them considered college as the “best” time of their life.Not all of them went to college,but still in most cases their teens and twenties were not the best times of their life.They said some of their favorite times were raising their children,traveling after retirement,and even enjoying their present time and age.
Enjoying one’s present time and age was a clear theme of the interviews.A piece of advice given by the women was about the importance of making the best of all situations.I think it more accurate than that of my friend;I can say with certainty that if I am lucky enough to make it to 100.I refuse to spend the last 80 years of my life plummeting (跌落) downhill,or even leveling off.
I am sure that our eagerness and devotion will make us college students live a meaningful life.We will not just look backwards or miss our college days.We will look forward in excitement about continued journey uphill.

B.she is looking forward to living as a “real” person in college |
C.she becomes more and more uneasy with graduation |
D.she is satisfied with the college life but is hopeful for the future |
A.best time of life at youth |
B.life experiences and views |
C.different opinions about life |
D.favorite time with best friends |
A.she will not spend the rest of her time at college |
B.she will not just obtain a college level certificate |
C.she will not be satisfied with what she has already accomplished |

Although people have believed depression to be a problem among the rich and educated,studies show that depression is a problem among everyone.Over any sixmonth period,between five to seven percent of the world’s population will be suffering from a serious depression.Suicide rates among people suffering from the disease in its extreme,or clinical form were 80 percent higher than in the population at large,and sufferers were four times more likely to have heart attacks.People who suffer from depression often have problems sleeping,getting up on time,and doing work productively.
Depression,which researchers agree has its origin in the genes,brings loss of confidence and ability to concentrate—making it impossible for employees and managers to work efficiently.
Depression is made more serious in China by Chinese’s inability to face it.Many people believe that depressed people are either weak or lazy.Besides,there is no good treatment,with few specialists available.“Most patients in China just don’t get help,”a Chinese doctor says.“In my hospital,I have to see 30 or 40 patients in a morning,just have time to say ‘Hello,how do you feel?’”
In Western countries,people are not afraid to admit that they have depression,but most do not tell it to their boss,because they fear that they will be stricken_off_the_rolls.“In my experience,aging bosses are the most willing to admit they have it.Because they feel the most secure about themselves,” an American doctor says.
Hopefully,in the near future,people around the world will be able to admit that they have depression so that they can get the right treatment.

C.working efficiently and productively |
D.either weak or lazy |
A.the understanding of the problem |
B.the lack of treatment and doctors |
C.their unwillingness to tell it to their boss |
D.the doctors’ careless work |
A.People are suffering from depression because of the shortage of specialists. |
B.The aging bosses around the world dare to say they are depressed. |
C.More and more patients will turn to specialists for help. |

To test how much dreams can help learning,Robert Stickgold had some students play a shapefitting game called Tetris (俄罗斯方块) for a few hours and then go to sleep.Soon they were dreaming of falling Tetris shapes.Interestingly,the worst Tetris players had the most Tetris dreams and improved their game the most.Similar tests have shown the same results for all kinds of skills.
As we dream,many important tasks are getting done.The brain decides what to keep and what to forget.It is connecting new experiences to older learning.In fact,the brain is learning all night long.
Another important task of dreams may be to help us deal with emotions (情绪).At night,emotions are in the driver’s seat.People who have had an upsetting experience often dream about it afterward.Often the dream event changes somehow—another way the brain tries to make the memory less upset.So if your best friend moves away,you might dream that you’re the one who’s moving.In fact,dreams have a proven power to improve mood,and people who dream about what’s bothering them usually feel better sooner than those who don’t.
Everybody dreams for a couple of hours every night—in the course of your life,you’ll spend about 25 years asleep and 6 years dreaming.There’s probably no single answer to the question why we dream,but there doesn’t have to be.One dream might help you remember your math facts,while another might lead to a new invention,or give you a fun,crazy story to tell your friends.It’s all in a night’s work for our busy,mysterious brains.
小题1:Robert Stickgold’s test shows that________.
A.games are useful for memory |
B.dreams can help improve skills |
C.players stop learning in dreams |
D.tasks can only be settled through dreams |
A.dreams can get rid of sufferings |
B.only drivers can deal with emotions |
C.one may be less upset after a dream |
D.dreams can copy what one experienced |
A.Dreaming does harm to one’s mood. |
B.Dreaming affects the quality of sleep. |
C.It’s hard to find out the secrets of dreaming. |
D.It’s not so important to know the cause of dreaming. |
A.Dreams and memories. | B.Dreams and emotions. |
C.The benefits of dreams. | D.The patterns of dreams. |
A.Entertainment. | B.Tourism. |
C.Science. | D.Advertisement. |
Making music is something that we are born with. There"s a reason we refer to music as the “universal language”;there has been no known human culture without music. Dancing and music came before agriculture, and possibly even before language.The fact that whale music and human music have so much in common suggests that music may exist before humans and that we may be latecomers to the musical scene rather than being the inventors of music.
We begin life being affected by music; babies first begin to respond to music even before their birth. Whether or not it"s true, everyone has heard that playing classical music; for your baby supposedly helps him or her become smarter. A study done in the United Kingdom concluded that children were able to recognize and even preferred music that they had heard lip to three months before birth. Although it made no difference whether it was rock music or country music, the babies who were exposed to faster songs showed a stronger preference for that song than those who had heard something slower. Researchers have also found that the playing of soft background music or a mother"s soft singing actually helps premature (早产的)babies. Those who were subjected to the music tended to gain weight faster and were able to leave hospitals earlier than those who weren"t. However, the study in the UK uncovers no links between babies listening to music and increased intelligence or brain development.
Another experiment at the University of California at Irvine compared the puzzle-solving abilities of 3-year-olds who were given piano lessons with the ability of others who sang, used computers, or did nothing. The children studying piano were better at the puzzles. Also, high school students with a musical background seem to do better on their SATs. Whether it"s natural intelligence that helps the children excel in both music and math, or the music that helps develop other areas, you can"t deny the benefits of a musical background.
On the other hand, it"s possible that some music and lyrics(歌词)could be hard for children and teenagers.The lyrics of today"s popular music are stated more and more clearly. A study oil mass media and teenagers showed that a group of 14- to 16-year-olds in 10 different southeastern cities listened to music an average of 40 hours per week. Obviously, the music they are listening to plays a large part in their lives,and especially influences self-identity. So any bad influences in the music will have a very direct effect on the teenagers. Several other experiments mentioned in the American Academy of Pediatrics" policy statement on the "Effect of Music Lyrics and Music Videos on Children and Youth" supported this idea. One study from Sweden found that children who developed a preference to rock music were more likely to be influenced by their peers than by their parents. Others showed links between a predilection for heavy metal and detrimental behaviors, including taking drugs, self-killing risk, and other risk-taking habits. The American Academy of Pediatrics (AAP) doesn"t support the idea of censorship(检查制度), but strongly encourages parents to monitor what their children are listening to.

We all have the ability to concentrate. Think of the times when you were attracted to a super novel or the times when you were playing your guitar or piano. But at other times your mind races from one thing to another. Here are some tips.
Rest from time to time. Remember to take short breaks. Lectures are usually 50 minutes long, and that’s about the length of time most people can direct their attention to one task. But that’s just an average. Your concentration time might be shorter (20-35 minutes) or longer (perhaps 90 minutes).When you take a break, you get more oxygen to your brain! When we sit for long periods, blood tends to be pooled in our lower body and legs. Get up and walk around the room for a couple of minutes. As a result, more oxygen is carried to the brain and you can concentrate better.
_______________If you study one subject for a long time, you may find it hard to concentrate. Many students improve their concentration by changing one subject to another every one to two hours. In this way you can pay more attention to something that’s different.
Reward yourself. Give yourself a reward when you’ve completed a task. The task might be small, such as staying with a difficult paper until you’ve finished. But giving yourself a reward can help you be more interested in doing other tasks.
Increase your activity level. Your concentration wanders more easily if you just read an article straight through. Instead, take the heading for each part and turn it into a question. For this part, that would be, “How can I increase my activity level while studying?” Then study that part to answer that question. Do this routinely. The questions give us a focus for each part and increase our involvement(参与).
小题1:According to Paragraph 3, what’s the purpose of walking around?
A.To help us stay fit. |
B.To benefit our lower body. |
C.To provide the brain with more oxygen. |
D.To increase our concentration time to 90 minutes. |
A.Study for one hour each time. |
B.Do something difficult. |
C.Study in different ways. |
D.Change subjects. |
A.we just read the heading of some articles |
B.we do our best to read an article straight through |
C.we ask ourselves questions about what we are reading |
D.we ask other people questions about the article we are reading |
A.encourage us to try to concentrate |
B.teach us how to concentrate while studying |
C.give us the reasons for a lack of concentration |
D.list the benefits we can get from concentration |
