Sorry to say,our brains naturally start slowing down at the Cruelty young age of 30.It used to be thought that this couldn’t be helped,but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,”saying University of California scientist Dr. Michael Merzenich.Given the right tools,we can train our brains to act like they did when we were younger.All that’s required is the practice designed just for the purpose:a few exercises for the mind.
Merzenich has developed a computer-based training method to speed up the process(过程) in which the brain deals with information (positscience.com).Since much of the data we receive comes through speech,the Brain Fitness Program works with language and hearing to better speed and accuracy(准确性).
Over the course of training,the program starts asking you to distinguish(辨别) sounds (between“dog”and“bog”,for example) at an increasingly faster speed.It’s a bit like tennis instructor,says Merzenich,hitting balls at you—faster and faster to keep you challenged(受到挑战).You may start out slow,but before long you’re pretty quick.
The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic.If you ask your brain to learn,it will learn.And it may even speed up while in the process.
To keep your brain young and plastic you can do one of a million new activities that challenge and excite you:playing table tennis or bridge,doing crossword puzzles,learning a language...“When it comes to preventing ageing,you really do ‘use it or lose it’,”says Barbara Sahakian,professor at Cambridge University.
Dr.Merzenich’s training method mainly depends on ______.
A.speech training
B.computer languages
C.the activities one joins in
D.the information being dealt with
By saying “the brain at any age is highly plastic”,the writer probably means the brain can be ______.
A.used B.mastered
C.developed D.researched
What can we learn from the text?
A.Practice makes a quick mind.
B.Brain research started ten years ago.
C.Dr. Merzenich is a scientist in computer.
D.People believed nothing could stop the brain slowing down.
Which of the following agrees with the writer’s idea?
A.The training methods work better for the old.
B.People should use the brain to stop it from ageing.
C.The training of the brain should start at an early age.
D.It’s necessary to take part in as many activities as possible.

How can you find out what is going on inside a person' s body without opening the patient up? Regular X-rays can show a lot. CAT scans can show even more. They can give three-dimensional(三维) view of body organs(器官).
What is a CAT scan? CAT stands for Computerized Axial Tomography(层面X线照相术). It is a special X-ray machine that gets a 360 - degree picture of a small area of a patient's body.
Doctors use X-rays to study and examine diseases and injuries within the body. X-rays can find foreign objects inside the body or to take pictures of some organs inside if special things as dyes or special liquids are added to the organs to be X-rayed.
A CAT scanner, however, uses a beam(光束) of X-rays to give a cross-sectional view of a particular part of the body. A fine beam of X-rays is scanned across the body and circled around the patient from many different angles(角度). A computer analyzes(分析) the information from each angle and produces a clear cross-sectional picture on the screen. This picture is then photographed for later use. Several cross-sections, taken one after another, can give a clear "photo" of the entire body or of any body organs. The newest CAT scanners can even give a clear picture of active, moving organs just as a fast-action camera can "stop the action" giving clear pictures of what appear only mistily(模糊) to the eye. And because of the 360 - degree pictures, CAT scans show 3-dimensional views of organs in a manner that was once only seen during surgery or autopsy (examining a dead body).
According to the first two paragraphs, doctors can see the inside of a patient's body by ______.
A. giving the patient an operation
B. checking body organs
C. getting a 360-degree picture of a small area of a patient's body
D. examining the CAT
From the last paragraph, we can infer that ______.
A. the newest pictures become more misty
B. many pictures can be taken at the same time
C. the information about the scanned patient is not highly valued
D. some pictures of the scanned parts of the body are developed for further examinations in the future
The best title of this passage might be ______.
A. Modern X-ray B. Three-dimensional View
C. Fast - moving Camera D. CAT Scan

A man was driving at 70 miles in a 40-mile-zone, when a police car came behind him with the flashers(警灯) on. As he pulled over and stopped, he could see a policeman getting out of his car. Right away the man started thinking of excuses to give, as this was not the first time, he had been in similar situations many times before.
As the policeman came to him, he said, “Hi, officer, I guess you caught me a little bit over the limit. I was in a rush to get home, to be with my wife and kids, you know my younger son wasn’t feeling too well, when I left home this morning.”
The policeman said, “Well, I guess so,” and started scribbling(速写) in his notebook. As minutes went by, he could see from the side view mirror, the policeman was still scribbling. The man was wondering why he hadn’t asked for his driver’s license so far. A few moments later, the policeman came to his window and handed him a folded paper, and returned back to his car without saying a single word. The man started to wonder, how much this ticket is going to be as he began to unfold the paper. He was surprised it was not a ticket as he began to read:
“I had a daughter who was killed by a speeding car at the age of six, by a speeding driver like you. He got a fine (惩罚), a few months in prison, and was free, free to hug his two other daughters. I only had one, and now I have to wait until I get to heaven before I can hug her again. I have tried to forgive that man a thousand times, and I thought I had. Maybe I really did forgive him, but I have to do it again, even right now. So pray(为……祈祷) for me, and be careful when you drive again, my son is all I have left.”
The man was completely dumbfounded(目瞪口呆的) and could not move for the next few minutes. When finally he did, he drove slowly, even a few miles under the speed limit, praying for forgiveness.
52. Why did the policeman stop the man?
A. Because the man drove after drinking.
B. Because the man drove at a speed of 40 miles an hour.
C. Because the man drove over the speed limit

53. Which statement is TRUE according to the article?
A. It was the first time that the man had driven over the limit a little bit.
B. He was in a rush to get home because his son was not feeling well.
C. This story happened in the morning.
D. The policeman didn’t believe the excuse the man gave.
54. From what the policeman said in Paragraph 4 we know that ______.
A. he wanted to go to heaven to hug his daughter
B. he recognized the man who had driven the speeding car who killed his daughter
C. the man who had killed the policeman’s daughter was free to do anything in prison
D. the man who had killed the policeman’s daughter hugged his own daughters in prison
55. Why did the man at last drive slowly?
A. Because he was afraid to be fined again.
B. Because he heard his son was feeling well.
C. Because he was driving in a 40-mile-zone.
D. Because he got a good lesson from what the policeman had written.

A few months ago, it wasn't unusual for 47-year-old Carla Toebe to spend 15 hours per day online. She'd wake up early, turn on her laptop and chat on Internet dating sites and instant-messaging programs – leaving her bed for only brief breaks. Her household bills piled up, along with the dishes and dirty laundry, but it took constant complaints from her four daughters before she realized she had a problem.
"I was starting to feel like my whole world was falling apart – kind of slipping into a depression," said Carla. "I knew that if I didn't get off the dating sites, I'd just keep going," detaching (使脱离) herself further from the outside world.
Toebe's conclusion: She felt like she was "addicted" to the Internet. She's not alone.
Concern about excessive Internet use isn't new. As far back as 1995, articles in medical journals and the establishment of a Pennsylvania treatment center for overusers aroused interest in the subject. But as reliance on the Web grows, there are signs that the question is getting more serious attention: Last month, a study published in CNS Spectrums claimed to be the first large-scale look at Internet overuse. The American Psychiatric Association may also consider listing Internet addiction in the next edition. And scores of online discussion boards have popped up, on which people discuss negative experiences tied to too much time on the Web.
The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the latest survey, this one was conducted by Stanford University researchers. About 6% of respondents reported that "their relationships suffered because of excessive Internet use." About 9% attempted to conceal "nonessential Internet use," and nearly 4% reported feeling " still occupied by the Internet when offline."
"The Internet problem is still in its early stage," said Maressa Orzack, a Harvard University professor. No single online activity is to blame for excessive use, he said. "They're online in chat rooms, checking e-mail, or writing blogs. The problem is not limited to porn (色情) or gambling websites.”
“Excessive Internet use should be defined not by the number of hours spent online but in terms of losses.”said Maressa Orzack. "If it's a loss where you're not getting to work, and family relationships are breaking down as a result, then it's too much."
Since the early 1990s, several clinics have been established in the U. S. to treat heavy Internet users. They include the Center for Internet Addiction Recovery and the Center for Internet Behavior.
The website for Orzack's center lists the following among the psychological symptoms of computer addiction:
● Having a sense of happiness or excitement while at the computer.
● Longing for more and more time at the computer.
● Neglect of family and friends.
● Feeling empty, depremssed or irritable when not at the computer.
● Lying to employers and family about activities.
● Inability to stop the activity.
● Problems with school or job.
Physical symptoms listed include dry eyes, backaches, skipping meals, poor personal hygiene (卫生) and sleep disturbances.
“People who struggle with Internet overuse maybe depressed or have other mood disorders.” Orzack said. When she discusses Internet habits with her patients, they often report that being online offers a "sense of belonging, and escape, excitement and fun," she said. “Some people say relief…because they find themselves so relaxed.”
Some parts of the Internet seem to draw people in more than others. Internet gamers spend countless hours competing in games against people from all over the world. One such game, called World of Warcraft, is cited on many sites by posters complaining of a "gaming addiction."
Andrew Heidrich, an education network administrator from Sacramento, plays World of Warcraft for about two to four hours every other night, but that's nothing compared with the 40 to 60 hours a week he spent playing online games when he was in college. He cut back only after a full-scale family intervention (干预), in which relatives told him he'd gained weight.
“There's this whole culture of competition that sucks people in with online gaming, ”said Heidrich, now a father of two. People do it at the expense of everything that was a constant in their lives." Heidrich now visits websites that discuss gaming addiction regularly “to remind myself to keep my love for online games in check”.
Toebe also regularly visits a site where posters discuss Internet overuse. In August, when she first realized she had a problem, she posted a message on a Yahoo Internet addiction group with the subject line:“I have an Internet Addiction.”
“I'm self-employed and need the Internet for my work, but I'm failing to accomplish my work, to take care of my home, to give attention to my children,”she wrote in a message sent to the group. “I have no money or insurance to get professional help; I can't even pay my loan and face losing everything.”
Since then, Toebe said, she has kept her promise to herself to cut back on her Internet use. "I have a boyfriend now, and I'm not interested in online dating," she said by phone last week. "It's a lot better now."
1. What eventually made Carla Toebe realize she was spending too much time on the Internet?
A. Her daughter's repeated complaints.
B. Tiredness resulting from lack of sleep.
C. The poorly managed state of her house.
D. The high financial costs adding up.
2.What is the main idea of para4?
A. A study claimed to be the first large-scale look at Internet overuse.
B. The American Psychiatric Association plans to list Internet addiction in its edition.
C. There are heated discussions about negative experiences over internet overuse.
D. There is a growing concern towards internet addiction.
3. According to Professor Maressa Orzack, Internet use would be considered excessive if ______.
A. it seriously affected family relationships
B. one visited porn websites frequently
C. too much time was spent in chat rooms
D. people got involved in online gambling
4. According to Orzack, people who struggle with heavy dependence on
the Internet may feel ______.
A. discouraged B. pressured C. depressed D. puzzled
5. Andrew Heidrich now visits websites that discuss online gaming addiction to _____.
A. improve his online gaming skills
B. control his desire for online gaming
C. show how good he is at online gaming
D. exchange online gaming experience
6.Which of the following best describes the tone(口吻) of the passage ?
A. Humorous B. Ironic C. Objective D. Casual
