Lights Out at Bedtime
There are plenty of good reasons to power up a personal desktop or laptop computer in the evening — writing e-mails，chatting on social networks or making purchases over the Internet，for instance．But various studies indicate that people who stare at a PC’s bright monitor shortly before going to bed probably sleep less soundly than they would otherwise because the light seriously affects their natural wake-sleep cycle．"They haven't proved it though，" says Dieter Kunz，the team's director at Charite's Psychiatric Clinic in St．Hedwig's Hospital in Berlin．
Similarly，exposure to just 10 minutes of normal bathroom lighting is enough to free the sleep hormone melatonin，which regulates people's natural wake-sleep cycle and makes them sleepy at nightfall．
Ten years ago，a team of British and American researchers detected a photo-pigment（光敏色素） in the human eye that signals to the body whether it is day or night，summer or winter．The photo-pigment is especially sensitive to blue light．
"The blue light more or less tells the body，'It's daytime，be awake，'" Kunz says．Monitors have a mostly cold white light content and scientists suspect the photo-pigment may react similarly to it．So the longer people look into the bright light，the more awake they become - and then sleep poorly．
A lot of people have difficulty "switching off" in the evening．About half of the women in Germany and a quarter of the men sleep poorly．
Environmental factors are only one of the possible causes．Job stress as well as personal and health concerns are also the main reasons for their sleep problems．
In addition，electronic objects' standby lights and indicator lamps can be annoying in the dark and affect sleep．"Sound scientific evidence is still lacking on this matter，" Kunz notes．
According to Kunz，those who cannot go without their computer in the evening should turn down the blue content if possible and lower the brightness somewhat．"But nobody does that because，after all，you want to concentrate while working at the computer and the light helps the brain．"
1.The passage is mainly about ____________．

How to Be Good at Sports
If sports are something that interests you, it stands to reason that you would want to be good at them. Here are some tips that can help you become a good player.
Set ambitious but realistic goals. If you want to be great at sports, you need to set your aims high. 1. Instead, you should take a look at what you are, and figure out where you think you would like to be. Give yourself a suitable amount of time to achieve that goal.
Be patient. 2. Impatient athletes tend to make poor ones. If you're not patient, you'll try to jump into advanced techniques long before you're ready. You'll feel discouraged when you don't see immediate improvement.
Join a sports team. Most of the sports teams are free to join. If you go to school, you should go for team tryouts when they're happening. 3.
Accept criticism. When you play sports, you will unavoidably receive criticism, whether from a coach or other players. 4. Are they angry because you missed a pass, or do they sincerely want to help you improve? In a lot of cases, you can use criticism as motivation to get better.
5. A skill become mastered when you’re able to do it without thinking. Given enough time and practice, a skill will eventually fall under this category. When in a game, you won't have time to think everything through, so practice until it's all automatic.
A. Skills are often slow to build.
B. This does not mean being unrealistic.
C. You need to take most of it with a grain of salt.
D. Practice until your skills become second nature.
E. You also need to be clear about what you are good at.
F. If you're not in school, you can find a sports club online.
G. An important reason people join sports teams is to make friends.

There are plenty of things to do while at home, from watching heartwarming TV to indoor fitness, but if you want to do something with the whole family, a board game is the perfect activity.
Telestrations
It is like a combination of the whisper game Telephone and Pictionary. Players draw a word and pass their sketch to the player next to them, who writes down the word they think the first player draws. The next player draws the word the previous player writes down, and the game continues in this way until the final drawing or description comes out wildly different from the original one. It is most popular among kids.
Catan
A slightly more involved game than Risk or Monopoly, Catan, previouly known as Settlers of Catan or Settlers, has become popular in the past decade or so beyond board game enthusiasts. In the game, which has many expansions available if you get bored with the original, players become “settlers”, each trying to build up individual settlements while trading resources. The bigger your settlement, the more points, and the first to a set number wins.
Ticket to Ride
It is an easy-to-understand game that is about something as simple as trains. Players use colored train cars that they are able to obtain by collecting cards of the same color to create train routes across a map of the U. S. Expansion packs have many other maps to choose from. Bigger train routes give you more points, as do building the routes shown on the secret ticket cards you draw at the beginning of the game.
Lords of Waterdeep
This board game from the makers of Dungeons Dragons is definitely more complex but is one of the most enjoyable games once you understand all the rules. Beautifully designed in fantasy style, Waterdeep is a “worker placement game”, in which players use agents to gather resources to complete quests, which generate victory points. Whoever has the most at the end of the game wins.
1.In which of the following board games is drawing needed?
A.Telestrations.
B.Catan.
C.Ticket to Ride.
D.Lords of Waterdeep.
2.Who will be the winner in Catan?
A.The one becoming the first settler.
B.The one getting needed points first.
C.The one gathering the most resources.
D.The one creating the most train routes.
3.What do the four board games have in common?
A.They have many expansions.
B.They ask players to get points.
C.They involve more than one player.
D.They are easy to understand and play.

My bookshelves are full of dust — and with good reason. When it comes to cleaning that part of my home, I suffer from the most serious case of avoidance (回避反应症).
The thing is this: when I do set out to clean and re-organize my books, which seldom happens, I place myself into a really bad situation. No sooner do I take a title from the shelf, blow off the dust, and wipe down the cover than I find myself sitting on the floor with legs crossed and my back against the wall. Pretty soon books get piled up on my legs as I am reunited with old friends.
It is as if these books have voices, and each wants to say its piece. “Remember me? I was given to you when you went into the Navy, so that you would never lack for companionship,” one whispers. Another says, “I was your first book of poems, given to you before you learned to love poetry.” And a third, “I was the book that made history so attractive to you.”
Perhaps the greatest pleasure of re-organizing my books are the surprises — or better said, reunions — that occur. During my latest book-cleaning adventure, I found one that had fallen behind the shelf: “Tales of Edgar Allan Poe.” Not an unusual title, but the words written on the first page made it very special: “With Love from Mom and Dad, Christmas 1965.” What’s this? A book on the physics of lasers（激光）. It is filled with mathematical statements, and I had bought it at a library sale when I was 12, not long after the laser had been invented. I couldn’t understand a bit of it, but I did learn what “laser” meant.
What I end up with when I empty my bookshelves is a cross-section (横剖面) of my personal history. It’s like a road cut where one sees all the layers of rock going back through time to the beginning of the simplest life forms. The books I’ve read — and kept — are not just old friends. They are my résumé.
1.What could be said about the author?
A．He is too busy to tidy up his bookshelves.
B．He considers his books treasured possessions.
C．He has made a lot of notes in his books.
D．He is a lover of science books.
2.By saying that his books have voices, the author means ________ .
A．they bring back happy memories
B．they are recorded in human voice
C．they say a lot about human history
D．they offer good topics for discussion
3.What does the author enjoy most from re-organizing his books?
A．Finding some missing books.
B．Putting books in good order.
C．Learning something new from the books.
D．Rediscovering interesting stories behind some books.
4.The underlined word “résumé” in the last paragraph probably means ______.
A．personal history B．precious notes C．good companion D．simple life forms

Whether we’re 2 years old or 62, our reasons for lying are mostly the same: to get out of trouble, for personal gain and to make ourselves look better in the eyes of others. But a growing body of research is raising questions about how a child’s lie is different from an adult’s lie, and how the way we deceive changes as we grow.
“Parents and teachers who catch their children lying should not be alarmed. Their children are not going to turn out to be abnormal liars,” says Dr. Lee, a professor at the University of Toronto and director of the Institute of Child Study. He has spent the last 15 years studying how lying changes as kids get older, why some people lie more than others as well as which factors can reduce lying. The fact that children tell lies is a sign that they have reached a new developmental stage. Dr. Lee conducted a series of studies in which they bring children into a lab with hidden cameras. Children and young adults aged 2 to 17 are likely to lie while being told not to look at a toy, which is put behind the child’s back. Whether or not the child takes a secret look is caught on tape.
For young kids, the desire to cheat is big and 90% take a secret look in these experiments. When the test-giver returns to the room, the child is asked if he or she looked secretly. At age 2, about a quarter of children will lie and say they didn’t. By 3, half of kids will lie, and by 4, that figure is 90%, studies show.
Researchers have found that it’s kids with better understanding abilities who lie more. That’s because to lie you also have to keep the truth in mind, which includes many brain processes, such as combining several sources of information and faking that information. The ability to lie — and lie successfully — is thought to be related to development of brain regions that allow so called “executive functioning”, or higher order thinking and reasoning abilities. Kids who perform better on tests that involve executive functioning also lie more.
1.What’s the purpose of children telling lies?
A. To help their friends out. B. To get rid of trouble.
C. To get attention from others. D. To create a popular image.
2.The underlined word “deceive” in Paragraph 1 can be replaced by “ ”.
A. tell lies B. handle troubles
C. raise questions D. do research
3.From the second paragraph we can know that .
A. which factors can reduce lying
B. why some lie more than others
C. it is normal for kids to tell lies
D. how lying changes as kids grow
4.It can be inferred from the passage that .
A. children’s lies are the same as adults’
B. the better kids are, the more they lie
C. the older kids are, the more they lie
D. kids always keep the truth in their mind
5.What is NOT included in the passage?
A. The reasons why kids tell lies.
B. Which kind of kids tells more lies.
C. Experiments about lying of young kids.
D. What to do with lying children.
