The Internet has led to a huge increase in credit-card (信用卡) fraud. Your card information could even be for sale in an illegal web site(非法网站).
Web sites offering cheap goods and services should be regarded with care.
On-line shoppers who enter their credit-card information may never receive the goods they thought they bought. The thieves then go shopping with your card number — or sell the information over the Internet. Computers hackers(黑客) have broken down security(安全) systems, raising questions about the safety of cardholder information. Several months ago, 25, 000 customers of CD Universe, an on-line music retailer(零售商), were not lucky. Their names, addresses and credit-card numbers were posted on a Web site after the retailer refused to pay US $157, 828 to get back the information.
Credit-card firms are now fighting against on-line fraud. Mastercard is working on plans for Web — only credit card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated(欺骗).
Ask about your credit-card firm’s on-line rules: Under British law, cardholders have to pay the first US $78 of any fraudulent(欺骗性的) spending.
And shop only at secure sites; Send your credit-card information only if the Web site offers advanced secure system.
If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Website address may also start https: //—the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.
Keep your password(密码) safe: Most on-line sites require a user name and password before placing an order. Treat your passwords with care.

New Zealand fishermen caught what may prove to be a world-record-breaking colossal squid (巨大的鱿鱼).
In the cold, dark waters of the Antarctic hides a creature with eight arms, two super long tentacles (触须) and eyes as big as dinner plates. Sound like something out of a science fiction movie? Think again.
On February 21, New Zealand fishermen landed a colossal squid the length of a school bus. They had been fishing with long lines for Chilean sea bass (黑鲈) in the waters off the coast of New Zealand when they caught the rare squid. With two hours of hard work, the crew skillfully pulled the creature into a net and dragged it aboard their ship.
Scientists estimate (估计) that the animal weighs about a half ton and is about 40 feet long. That would make this colossal squid the biggest on record.
First identified in 1925 after two tentacles were found in a whale’s stomach, the colossal squid has long been a mystery. The animals are not easy to observe because they can go down to ocean depths of 6,500 feet. What scientists do know from studying the bodies of a half dozen colossal squids is that they are fierce hunters.
The recently captured colossal squid has been frozen to keep it for scientific study. It will be transported to New Zealand’s national museum, Te Papa, in the capital city of Wellington. Experts believe it to be the first adult male ever caught undamaged. Scientists hope to learn more about the colossal squid’s diet, behavior and reproductive (繁殖) patterns.
“Scientists will be very interested in this amazing creature,” said New Zealand Fisheries Minister Jim Anderton. “It adds immeasurably to our understanding of the marine environment.”

  1. 1.

    Why is it usually difficult for experts to observe the squid?

    1. A.
      Because it moves too fast
    2. B.
      Because it is too large
    3. C.
      Because it is very dangerous
    4. D.
      Because it can go down to deep ocean
  2. 2.

    What can be inferred from the passage?

    1. A.
      The squid is from a science fiction story
    2. B.
      The fishermen often meet colossal squids
    3. C.
      Scientists know much about the colossal squid
    4. D.
      The fishermen had some difficulty catching the large squid
  3. 3.

    What’s the purpose of catching such a huge squid?

    1. A.
      To make it into food
    2. B.
      To set a world record
    3. C.
      To do research on it
    4. D.
      To display it for visitors
  4. 4.

What is language for? Some people seem to think it's for practising grammar rules and learning lists of words—the longer the lists,the better. That's wrong. Language is for the exchange(交流)of ideas and information. It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently(流利地). They are afraid of making mistakes. One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too. Bernard Shaw once wrote, "Foreigners often speak English too correctly. "But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language. And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right. People not only make history, they make language. But a people can only make its own language. It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo(做过头)it. They should put communication(交际)first.

  1. 1.

    Language is used to ________.

    1. A.
      express oneself             
    2. B.

      talk with foreigners only

      often makes mistakes
    3. C.
      can't avoid making mistakes        
    4. D.
      always makes mistakes
  3. 3.

Our cat has a sweet nature, and she can let us know what she wants. When we fail to meet her needs, she gently leads us in the proper direction. When I forget to fill her water bowl early in the morning, she runs after my legs, and then pushes me in the direction of her bowl. She doesn’t get irritated (生气的); instead, she expresses her wishes in the best way. And I always understand what she is telling me.
One day I found myself envying (羡慕) her simple expression. How many times had I expected my husband or my children to know my wants without my ever giving voice to them? How many times had I been disappointed that they couldn’t understand when I needed a hug, a compliment (恭维) or a chocolate bar?
After a pleasant afternoon with my husband, I wanted to stop somewhere nice and have dinner, but he didn’t understand my hints (暗示). “Couldn’t you see that I wanted to go out to dinner?” I complained when he pulled into our driveway.
“Why didn’t you say so? I can’t read your mind,” he answered in impatience. His words gave me pause. Had I expected him to read my mind? Why hadn’t I expressed my desire more clearly? I realized I had fallen into the female trap of “If you love me, you can read my mind.”

People being tested for radiation exposure

The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland.
Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation.
JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers."
For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident.
Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water.
JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables."
The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean.
JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of dilution. So the concentration of radioactivity in the seawater would still be quite low."
Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says.
Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry.
A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths.
The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen.

When you’re surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?
According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters- to record the computer user’s age, gender, location, favorite movies and hobbies.
The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated(高科技) software called a "beacon" to capture what people are typing on a website.
Lotame packages that data into profiles(个人资料)about individuals, only without their names, and sells the profiles to companies seeking customers.Batches of such data may be sold for a few dollars.
The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web.
The "cookie"- a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news.There are new and more complex tools such as "beacons" which scan in real time what people are doing on a webpage.These beacons instantly assess the Internet user’s location, income, shopping interests and even medical conditions.
Millions of Internet users around the world also face unprecedented(空前的)threats.Private, sensitive, personal and business information is being gathered and sold without their knowledge.
Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don’t know that they were installing intrusive files on visitors’ computers.These include MSN.com and Yahoo.com.

Linda Evans was my best friend—like the sister I never had. We did everything together: piano lessons, movies, swimming, horse back riding.
When I was 13, my family moved away. Linda and I kept in touch through letters, and we saw each other on special time—like my wedding and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address Unknown. ” I had no idea how to find Linda.
Over the years, I missed Linda very much. I wanted to share happiness of my children and then grandchildren. And I needed to share my sadness when my brother and then mother died. There was an empty place in my heart that only a friend like Linda could fill.
One day I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman — Linda’s married name. “There must be thousands of Wagmans,” I thought, but I still wrote to her.
She called as soon as she got my letter. “Mrs Tobin!” she said excitedly, “Linda Evans Wagman is my mother. ”
Minutes later I heard a voice that I knew very much, even after 40 years, laughed and cried and caught up on each other’s lives. Now the empty place in my heart is filled. And there’s one thing that Linda and I know for sure: We won’t lose each other again!

Lisa was running late. Lisa, 25, had a lot to do at work, plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Lisa felt weak and tired—maybe it hadn’t been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks.
Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.
But when he heard the scream, followed by someone yelling, “Oh, my God, she fell in!” Frank didn’t hesitate(犹豫). He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. “No! Not you! ”his girlfriend shouted after him.
She was right to be alarmed. By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.
It was hard to lift her. She was just out. But he managed to raise her four feet to the platform(站台) so that bystanders could hold her by the legs and drag her away from the edge. That was where Lisa briefly regained consciousness(知觉), felt herself being pulled along the ground, and saw someone else holding her purse.
Lisa thought she’d been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn’t, and that was when she realized how much pain she was in.
Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown - just as he had been seconds after the rescue(营救), which made her think about her reaction at the time. “I saw the train coming and I was thinking he was going to die,” she explained.
