Do you sleep well? Some people get off to sleep as soon as the head hits the pillow, but many others are not so lucky.In fact,the lack of quality sleep has become a public health issue around the world.According to the World Association of Sleep Medicine,45 percent of the world’s population suffer from sleep problems.One in eight people don’t sleep well and are easily woken.7.6 percent sleep less than 3 hours each night.Some even can not fall asleep for several days in a row.
As a basic bodily and mental need,sleep is essential for our survival.It helps us to fight diseases,strengthen our memory, perform better in work and school and improve our quality of life.Lack of sleep is known to have a significant negative influence on health,both in the short and long term.Poor sleep has been associated with obesity, weakened immune systems and even some cancers,as well as depression and anxiety.
The World Sleep Day, held on the third Friday of March,is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders.
Unhealthy lifestyle may be the first to blame for sleeplessness.More and more people use cellphones and computers in bed,with many staying up until midnight.Modern technology does make our life convenient,but abuse of it ruins our health.Environmental conditions,such as temperature,noise,light,bed comfort also play an important role in one’s ability to get proper sleep.Besides,improper evening diet,like a full or an empty stomach,coffee and alcohol all contribute to sleep problems.Of course,when it comes to causing poor sleep stress from finances,family or work should never be ignored.
However, those who suffer from sleep disorders don’t necessarily have to continue to do so—most sleep problems can be solved.
What can be inferred from Paragraph 1 ?

A.Nobody can stay awake for several days.
B.All people are going through sleep problems.
C.Sleep problems have become a worldwide concern.
D.The majority of the world’s population can’t sleep well.

What does Paragraph 4 mainly tell us?

A.The influences of lack of sleep.
B.The possible causes of poor sleep.
C.Poor sleep is associated with illness.
D.Good sleep helps us to perform better.

What will be discussed in the paragraph that follows?

B.Activities on the World Sleep Day.
C.Interviews of poor sleep sufferers.
D.Measures against sleep problems.

Walking down a path through some woods in Georgia, I saw a small pool of water ahead on the path.I angled my direction to go around it on the part of the path that wasn't covered by water or mud.As I reached the pool, I was suddenly attacked! Yet I did nothing for the attack.It was so unpredictable and from somewhere totally unexpected.I was surprised as well as unhurt though I had been struck four or five times.I backed up a foot and my attacker stopped attacking me.Had I been hurt I wouldn't have found it amusing.And I was laughing.After all, I was being attacked by a butterfly!
Having stopped, laughing, I took a step forward.My attacker rushed me again.He charged towards me at full speed, attempting to hurt me but in vain.For a second time, I took a step backwards while my attacker paused.I wasn't sure what to do.After all, it's just not everyday that one is attacked by a butterfly.I stepped back to look the situation over.My attacker moved back to land on the ground.That's when I discovered why my attacker was charging me only moments earlier.He had a mate and she was dying.
Sitting close beside her, he opened and closed his wings as if to fan her.I could only admire the love and courage of that butterfly in his concern for his mate.He had taken it up on himself to attack me for his mate's sake (缘故), even though she was clearly dying and I was so large.He did so just to give her those extra few precious moments of life, should I have been careless enough to step on her.His courage in attacking something thousands of times larger and heavier than himself just for his mate's safety seemed admirable.I couldn't do anything other than reward him by walking on the more difficult side of the pool.He had truly earned those moments to be with her, undisturbed.
Since then, I've always tried to remember the courage of that butterfly whenever I see huge barriers facing me.

New technology that can “ see ” through clothing and detect what ’ s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places.
The Thru Vision T5000 camera picks up Terahertz rays ,or T-rays, which are naturally sent out by all objects and can pass through clothes or even walls. The camera can then detect metallic and nonmetallic objects hidden under clothing on still or moving subjects without showing any body detail.
While similar technology is seen at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottle-necks at border crossing or security checkpoints. It also means people can be screened without knowing it.
The technology develops from British astronomers ’ work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space. The company sees uses for its camera at other sites where political or business activities take place.
For privacy concerns,Thru Vision Chief Executive Clive Beattie said the image produced by the camera did not show detailed parts of the body. ” It's almost a shining light bulb(灯泡).“ Beattie said. "You don' t see the detail that people might be concerned about. “ In London' s busy Piccadilly Circus—which is already filled with closed -circuit surveillance (监视)cameras— reaction to the new technology was mixed. Some said the camera was going too far and violating privacy,but others said they are willing to put safety before privacy concerns. “ There ’ s surveillance everywhere anyway, “ said one commuter. “I don' t think it’ s much of a difference. I don' t care that they can see through me because they can see me anyway.“
Some experts said the privacy violation of the camera was not worth the benefit. “ What we should consider is how much we want to lose our privacy in order to obtain a sort of national security,” said David Murakami Wood,director of the Surveillance Studies network,which deals with surveillance and privacy problems. “ In most cases this isn' t real security—it ’ s a sense of safety that has very little real effect. ”

Getting your teen to think beyond his own immediate needs can be more difficult than cracking a nut with a plastic fork.But don't worry.It's not impossible.There are many ways to encourage your teen to care about those outside his immediate circle of friends.As he begins to have responsibility towards others, he will realize he feels even better about himself.
"Teens are thinking about career, college, and what their future might look like," explains Michelle Maidenberg, a clinical director of Westchester Group Works, a center for group treatment in New York."This is very challenging and just one of the reasons why they are so focused on their own world." Once teens participate in community service, however, they begin to look beyond their personal needs.They also learn firsthand about the challenges others face, and they experience a sense of authority as they realize they can make a real difference in others' lives.
Not sure how to convince a teen to get away from the cell phone and into a community project? Teens buy into community service when the project or program is in an area of their interest.
"Finding something in an area of interest for them keeps them motivated and inspired," Maidenberg says.For instance, if he is interested in culinary (烹饪) school, he could volunteer in a soup kitchen or bake for a project that supports families in need.Volunteer projects in your teen's area of interest will build her knowledge base as well as help others.
Parents can do their part by participating in community service themselves.Teens can learn directly from their parents that personal enjoyment is not ,all that matters.
Let teens know the benefits they will obtain.“Give them every reason in the world to volunteer," Maidenberg advises.She says that working on community service projects builds confidence."By working with others, teens improve managerial, interpersonal and communication skills.Community service helps to approach maturity when they take a step back to see the needs of other people," she adds.Another reward: service hours look great on a resume!

My students often tell me that they don’t have “enough time” to do all their schoolwork.
My reply is often a brief “You have as much time as the president.” I usually carry on a bit about there being twenty-four hours in the day for everyone, and suggest that “not enough time” is not an acceptable explanation of not getting something done.
Once in graduate school, I tried to prove to one of my professors by saying that I was working hard. His answer to me was, “That’s irrelevant (无关的). What’s important is the quality of your work.” Since then I have had time to think carefully about the “hard worker” dodge (诀窍), and I have come to some conclusions — all relevant to the problem of how much time we have.
If you analyze the matter, you can identify two parts of the problem: There is, of course, the matter of “time”, which we can think of as fixed. Then there is the problem of “work” during that time. But, as my professor suggested, it’s not how hard one works but the quality of the product that’s important.
That led me to a new idea: the quality of the work. That concept is perhaps best explained by a sign I once saw on the wall in someone’s office: “Don’t work harder. Work smarter.” There is a lot of sense in that idea.
If you can’t get more time, and few of us can, the only solution is to improve the quality of the work. That means thinking of ways to get more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work” for students usually means “homework”, the expression “work habits” should be read as “study habits”.
Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off in all your studies.

A Full-Time School Called Life
You are enrolled in a full-time school called “life”. Each day in this school you will have the opportunity to learn lessons. You may like the lessons or hate them, but you have designed them as part of your curriculum.
Why are you here? What is your purpose? Humans have sought to discover the meaning of life for a very long time. What we and our ancestors overlooked, however, is there is no one answer. The meaning of life is different for every individual.
Each person has his or her own purpose and distinct path, unique and separate from anyone else’s. As you travel your life path, you will be presented with numerous lessons that you will need to learn in order to fulfill that purpose. The lessons you are presented with are specific to you; learning these lessons is a key to discovering and fulfilling the meaning and connection of your own life.
As you travel through your lifetime, you may encounter challenging lessons that others don’t have to face, while others spend years struggling with challenges that you don’t need to deal with. You may never know why you are blessed with a wonderful marriage, while your friends suffer through bitter arguments and painful divorces, just as you cannot be sure why you struggle financially while your peers enjoy abundance. The only thing you can count on for certain is that you specifically need to learn; whether we choose to learn them or not is entirely up to you.
The challenge here, therefore , is to align(与…保持一致)yourself with your own unique path by learning individual lessons. This is one of the most difficult challenges you will be faced with in your lifetime, as sometimes your path will be completely different from others. But, remember, don’t compare your path to the people around you and focus on the difference between their lessons and yours. You need to remember that you will only be faced with lessons that you are capable of learning and are specific to your own growth.
Our sense of fairness is the expectation of equity—the assumption that all things are equal and that justice will always prevail. Life is not, in fact, fair, and you may indeed have a more difficult lift path than others around you, deserved or not. Everyone’s circumstances are unique, and everyone needs to handle his or her own circumstances differently. If you want to move toward calm, you will be required to move out the comparing phrase of “it’s not fair”. Focusing on the unfairness of circumstances keeps you comparing yourself with others rather than appreciating your own special uniqueness. You miss out on learning your individual lessons by distracting yourself with feeling of bitterness and anger.
.According to the passage, how can the meaning of your life be realized?

A.Having the same opinions as others.
B.Taking the distinct path from others.
C.Learning the lessons presented to you.
D.Doing the different things from others.

. From the passage we can conclude ______.

A.everyone has his own track to follow
B.the same thing usually happen to the peers
C.a painful divorce must lie in financial problems
D.a wealthy man must have a wonderful marriage

. In your lifetimes, the lessons you are faced with ______.

A.are beyond your power B.keep you from growth
C.limit your development D.help you with your success

. Which of the following is TRUE?

A.All things are equal and justice will always prevail.
B.You should learn to appreciate your specific uniqueness.
C.One has to fix his mind on unfairness of circumstances.
D.The teachers have designed the lessons as part of your curriculum in the life school..

. Life is called a full-time school, because ______.

A.it is full of all lessons to learn
B.you have plenty of time to learn lessons
