In today's world, we rely on computers as never before. They are used for everything from ordering a pizza to running hospitals and military defense systems. Banking and credit card information is stored and accessed by computers. So what happens when a computer gets infected with a virus? One effect is that people's access to their e-mail accounts is cut off. A more serious possible consequence is that billions of dollars could be lost.
A virus is a computer program that copies itself onto other programs and infects them. Similar to an easily spread disease, a computer virus goes from computer to computer, either adding to or changing the tasks a program is designed to do.
The first computer viruses were created in the mid '80s and had varying effects. Some caused files to be deleted, or made the letters on the screen appear to fall off. Others displayed a specific message once the computer was turned on.
Viruses today are much more widespread and dangerous than ever before. Perhaps the most damaging to date has been the "I Love You" virus. "I Love You" appeared in May 2000 and has possibly been the most destructive virus in terms of monetary loss.
The virus is released when an attachment to a fake e-mail message is opened. By changing the names of files on computers, "I Love You" makes them difficult to access. It also searches for important personal information, including passwords, which it sends to a web site for others to see.
It is estimated that more than 45 million people in 20 countries have had their computers infected by the "I Love You" virus. Some say the cost of repair and lost business has been more than US$10 billion.
If you own a computer, it is important to keep it in good health by installing an anti-virus program. If updated frequently, it will protect your e-mail access--not to mention your wallet.

Dr．Sylvia Earle wants you to stop eating fish．It’s not because fish are endangered, though wild fish stocks in many oceans are very low．It’s not because they’re bad for you, though fish in many areas are exposed to poisonous substances in the water．It’s because they’re smart．
“Fish are sensitive, they have personalities,” says the marine biologist．For Earle, eating a fish would be like eating a dog or a cat．“I would never eat anyone I know personally.”
There’s a lot more to fish than meets the eye: they talk to each other, they like to be touched, and they engage in behavior that can seem very human．They can remember things and learn from experience．Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether．
The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket．“While it may seem obvious that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables,” says Dr．Lynne Sneddon．“Really, it’s kind of a moral question．Is the enjoyment you get from fishing (or eating fish) more important than the pain of the fish?”
Fishermen and (fried) fish lovers are doubtful．“I’ve never seen a smart fish,” says Marie Swaringen as she finishes off a plate of fish at a Seattle seafood restaurant．“If they were very smart,
they wouldn’t get caught.”
“For years, everyone’s been telling us to eat fish because it’s so good for us,” says another diner．“Now I’ve got to feel guilty while I’m eating my fish? What are they going to think of next? Don’t eat salad because cucumbers have feelings?”
64．Dr．Sylvia Earle discourage people from eating fish because _____________.
A．there are not that many wild fish in the ocean
B．fish actually are sensitive and have personalities
C．some ocean fish contain poisonous substances
D．fish are like dogs or cats that people know personally

A．all people don’t agree with the idea to stop eating fish
B．people will be persuaded not to eat fish in the future
C．stopping eating fish will lead to people’s not eating vegetables
D．we shouldn’t care too much about the feeling of fish
66．By saying “There’s a lot more to fish than meets the eye,” the writer means ____________.
A．there are far more fish than other animals in the world
B．there are more fish in the world than people can see

D．fish are not that simple as they appear to people’s eyes
67．What is the writer’s attitude towards people eating fish?

The British last an average of eight minutes and twenty-two seconds before they lose temper, according to new research.
The Internet has increased people’s service demands and it is destroying the classic British characteristic of patience．More than half of the British have admitted they lose their temper quicker than ever before．People have become so used to the speed and convenience of the Internet that more than seven in ten get angry if forced to wait longer than one minute for a web page to download．
Being kept on hold made the British see red more than anything else, with the average person reaching their impatience limit after five minutes and four seconds.
In today’s fast food culture, restaurant rage starts after only eight minutes and thirty-eight seconds, when the average diner will start to wonder whether the meal they have ordered will ever arrive.
People running late to meet a friend should not leave it any longer than ten minutes and one second if they do not want to face their anger.
Finally, when receiving a text or voicemail, be warned that the clock is ticking as the average Englishman expects a response within thirteen minutes and sixteen seconds.
Mark Schmid, of telecom giant TalkTalk, which conducted the research among 2,050 people, said that the speed of the online world is making us less prepared to wait for things to happen in the offline world．“This is causing people to reach the point of impatience earlier than ever before.”

The dog that gave us the most trouble was a beagle (猎兔犬) named Murphy．As far as I’m concerned, the first thing he did wrong was to turn into a beagle．I had seen him bounding around on the other side of a pet-shop window, and I went in and asked the man, “How much is that adorable fox terrier (小猎狗) in the window?” Did he say “That adorable fox terrier is a beagle”? No, he said, “Ten dollars, lady.” Now, I don’t mean to say one word against beagles．They have rights just like other people．But it is a bit of a shock when you bring home a small ball of fluff (绒毛) in a shoebox, and three weeks later it’s as long as the sofa．
Murphy was the first dog I ever trained personally, and I was delighted at the enthusiasm with which he took to the newspaper．It was some time later that we discovered, to our horror, that—like so many dogs—he had grasped the letter but not the spirit of the thing．Until the very end of his days he felt a real sense of duty whenever he saw a newspaper—any newspaper—and it didn’t matter where it was．I can’t bring myself to go into the details, except to mention that we were finally forced to keep all the papers in the bottom of the icebox．
He had another habit that used to leave us open to a certain amount of criticism from our friends．He never climbed up on beds or chairs or sofas．But he always sat on top of the piano．In the beginning we used to try to pull him off．But after a few noisy fights in which he knocked a picture off the wall, scratched the piano, and smashed a lamp, we just gave in—only to discover that he hopped up and down as skillfully as a ballet dancer．
Nowadays if I go anywhere, I just ask if they have a dog．If they do, I say, “Maybe I’d better keep away from it—I have bad allergy.” This sometimes annoys the host．But it works．It really works.

Sport is not only physically challenging，but it can also be mentally challenging. Criticism from coaches，parents，and other teammates，as well as pressure to win can create an excessive amount of anxiety or stress for young athletes. Stress can be physical，emotional，or psychological，and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.
The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can，for example，learn how to cooperate with others，make friends，and gain other social skills that will be used throughout their lives. Coaches and parents should be aware，at all times，that their feedback to youngsters can greatly affect their children. Youngsters may take their parents’ and coaches’ criticisms to heart and find flaws（缺陷）in themselves.
Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting，young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game, many parents and coaches focus on the outcome and find fault with youngsters’ performances. Positive reinforcement（正面强化）should be provided regardless of the outcome. Research indicates that positive reinforcement motivates and has a greater effect on learning than criticism. Again，criticism can create high levels of stress, which can lead to burnout.
72．An effective way to prevent the burnout of young athletes is ____________.
A．to make sports less competitive
B．to make sports more challenging
C．to reduce their mental stress
D．to increase their sense of success
73．According to the passage sport is positive for young people in that____________.
A．it can help them learn more about society
B．it teaches them how to set realistic goals for themselves
C．it enables them to find flaws in themselves
D．it can provide them with valuable experience
74．Many coaches and parents are in the habit of criticizing young athletes ________.
A．without realizing criticism may destroy their self-confidence
B．in order to make them remember life lessons
C．believing that criticism is beneficial for their early development
D．so as to put more pressure on them
75．The author’s purpose in writing the passage is ____________.
A．to persuade athletes not to worry about criticism
B．to emphasize the importance of positive reinforcement to young athletes
C．to discuss the skill of combining criticism with encouragement
D．to teach young athletes how to avoid burnout

The largest earthquake （magnitude 里氏 9．5） of the 20th century happened on May 22,1960 off the coast of South Central Chile．
It generated（生成） one of the most destructive Pacific-wide tsunamis（海啸）．Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isia Chiloe．The largest tsunami damage occurred at Isia Chiloe—the coastal area closest to the epicenter（震中）．Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland．
