阅读理解专题卷19
Some kids can't sit still for long. They have a hard time paying attention to just one thing. They're easily distracted(分神).They can get very impatient. They hate standing in line or waiting for their turn in a game or activity. They get bored pretty fast. They may also be impulsive—saying the first thing that comes to mind or interrupting someone else who's talking.
For certain kids, this problem is so severe(严峻) that doctors have a name for it: attention deficit hyperactivity disorder, or ADHD. Perhaps as many as 1 out of every 20 kids under the age of 18 have characteristics of ADHD. Often, these kids have trouble getting through school and face other difficulties later in life.
Rizzo started developing the Virtual Classroom in 1999.He wanted to see if he could use it as a tool for testing and treating kids who have attention disorders.
To diagnose(诊断) ADHD, doctors typically test patients by giving them tasks that require attention. As part of one classic test, you watch letters flashed on a computer screen. Every time you see the letter “A” followed by the letter “X”,you have to press the space bar. If you're paying close attention, you'll register all the times this combination occurs. If not, you'll miss some.
The Virtual Classroom makes these tests more efficient, Rizzo says. In one experiment, he gave a group of kids the classic “A-X” test. Instead of looking at a computer screen in a doctor's office, though, the kids wore headsets that made it look like they were taking the test in a classroom.
“Basically what we found,”Rizzo says,“is that, in 20 minutes of testing with virtual reality,we replicated(复制) a finding that usually requires a couple hours of standard testing with computer screens in the psychologist's office.”

Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut,” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up（蜷伏）with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list,” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years,” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

A. Teenagers talk a lot with their friends.
B. Teenagers do not want to understand their parents.

When TV news programs report wars or disasters, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they may find some of these scenes disturbing, so they can look away if they choose. But the men and women whose job is to record those scenes－the TV cameramen－have no such choice. It is their duty to witness the horrors of the world and record them, no matter how terrible and unpleasant they may be. Consequently, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer.
Today, the demand for their work is rising. The explosion of satellite broadcasting and 24-hour news in recent years has created an almost insatiable (贪得无厌的) demand for TV information. But major broadcasters and the TV news agencies—such as Reuters and WTN－have never had enough staff to meet the worldwide demand for up-to-date pictures, so increasingly they turn to “freelance” TV cameramen.
These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, be it for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelancer must survive on his own.
TV will always need hard, vivid moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books, explains Nick Growing, once foreign editor for Britain Channel 4 News and now a BBC news presenter.
By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to contract out the risk, he says.

C. are responsible for the freelancer if he is injured
12．The author of this passage shows his the freelance cameramen.
A. sympathy to B. respect for C. anger to D. admiration to

CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards.
A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle.
Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat.
"Most people don't give much thought to the grime that builds up on their PC, but if you don't clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement.
The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria.
Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards.
But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse.
Almost half -- or 46 per cent -- cleaned their keyboard less than once a month.
To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them.
13．The purpose of the passage is .
A. tell us something about the keyboards.
B. warn people to clean the keyboards often.

D tell us the germs on keyboards
14．What do you think the expression “Think twice before eating those dropped crumbs off your computer keyboard” stands for?
A. Think several times before eating beside your computer
B. Don’t drop foods onto the computer keyboard.
C. Don’t eat foods dropped onto the computer keyboard.
D. Be careful when you are eating by the computer.
15．What are the main causes of a bug-infested keyboard?
A. Dropped crumbs and food encourages the growth of millions of bacteria.
B. Poor personal hygiene
C. Much dirt on the computer keyboard.
D. Dropped crumbs and food and Poor personal hygiene
16．"Which? Computing" is probably a name of .

Think of some of your favorite singers. When you listen, they can make you happy or sad, peaceful or angry. They can make you relax or want to get up and dance. Gifted singers have the power to affect us in many ways—emotionally, physically and mentally.
But becoming a great singer isn’t as easy as listening to one. It takes practice, devotion and strong lungs! Just ask the well-known American opera（歌剧）star Carol Vaness.
At the Metropolitan Opera in New York City where she often sings, Carol’s voice must be loud enough to be heard by four thousand people. It must reach every person in the theater, without a microphone, even when she’s singing softly. The reason Carol can project her voice that far is the way she breathes.
“When you breathe, it’s like a swimmer taking a deep breath before going underwater,” Carol explains. “You have to take a lot of air into your lungs.”
According to Carol, the main difference between pop singing and opera is “how you breathe, how much air you take in, and how you control it coming out. Regular singing is more like speaking, and it’s lot softer. When I sing for children, they’re often surprised by how the vibrations strike their ears—like waves on a beach, ”Carol says. “In opera, the air doesn’t just go out of your mouth—it vibrates in your chest，the way a guitar vibrates when it’s played.”
Ever since she started piano lessons at the age of ten, Carol has loved music. As she got older, she decided to become a music teacher. When she went to college, she took singing lessons as part of her studies. Her voice teacher discovered that nineteen-year-old Carol had an exceptionally beautiful soprano voice-the highest singing voice for women.
Carol decided to make opera her goal, not only because she loved to sing but also because she loved the drama. Opera is a play in which the characters sing the words instead of speaking them. The stories of opera can be tragic or comical. They can be personal stories about two people falling in love or grand stories about kings and queens who lived long ago. As the characters in an opera sing, the emotions（情感）expressed by words and music come to life.
Today, Carol performs throughout the United States and Europe and she has song for almost twenty years. But she has never forgotten where she started singing in the first palace.
“Put your heart into your singing and enjoy it,” says Carol, “because singing is a great joy. That’s why I sing. In fact, that’s why everybody sings.”

B．Opera singing is more like speaking.
C．A pop singer takes in much more air than an opera singer when singing.

I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square, It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the s
