How to Beat On-line Credit-card Thieves
The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site.
Web sites offering cheap 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 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, and on-line music retailer（批发商）, were not lucky. Their name, 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. Master-card 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.
Ask about your credit-firm’s on-line rules. Under British law, cardholders are responsible for the first US $78 of any fraudulent 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 web site address may also start the extra “s” stands for secure.
If you still have any doubt, give your credit-card information over the telephone.
Keep your password safe: Most on-line sites require a user name and password before placing an order. Treat your password with care.

How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. 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 determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives

阅读下列短文，根据所读内容在表格中的空白处填入恰当的单词。注意：每个空格只填一个单词。

     Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing?
Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and
talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his
parents when he was a teenager.
    "I would never have said to my mom,' Hey, the new Weezer album is really great. How do you like it?'" says Ballmer. "There was just a complete gap in taste."
    Music was not the only gulf (分歧). From clothing and hairstyles to activities and expectations, earlier
generations of parents and children often appeared to move in separate orbits.
    Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are
comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust
and friendship that can continue into adulthood.
    No wonder greeting cards today carry the message, "To my mother, my best friends."
    But family experts warn that the new equality can also result in less respect for parents.
    "There's still a lot of strictness and authority on the part of parents out there, but there is a change
happening," says Kerrie, a psychology professor at Lebanon Valley College. "In the middle of that change, there is a lot of confusion among parents."
    Family researchers offer a variety of reasons for these evolving(演化的) roles and attitudes. They see
the 1960s as a turning point. Great cultural changes led to more open communication and a more
democratic process that encourages everyone to have a say.
    "My parents were on the 'before' side of that change, but today's parents, the 40-year-olds,were on
the 'after' side," explains Mr. Ballmer. "It's not something easily accomplished by parents these days,
because life is more difficult to understand or deal with, but sharing interests does make it more fun to be
a parent now."

Angus MacLeod was fifty and he had spent his entire life as a shepherd in the remote mountainous region of northwest Scotland. He had never owned a radio or television nor had he travelled further than forty kilometres from his birthplace. His knowledge of the world was gained only from his brief trips to the village to sell his sheep and buy food. However, he had lately come to rely on the growing number of hill-walkers in the region as sources of international news.
In the spring of 1992, a Spanish student came across Angus high in the mountains. Eager to practise his English he engaged Angus in conversation. The student told Angus of the forthcoming Olympic Games in Barcelona. Excited by the student's colourful description of Spain and the Games, Angus decided to attend the event in person and two months later arrived in Barcelona.
The ticketless Angus stood outside the stadium with his canny brain working overtime, watching a growing number of individuals entering the stadium through a small entrance at the side. He noticed that they all seemed to be carrying objects. Perhaps they were workmen, he thought. He moved closer and watched.
Within minutes a thin young man came along carrying an extremely long pole. He approached the official at the door and said "Pole Vault". The official moved to the side and the man entered. Next came a heavy-set man with a spear. Angus wondered how a man could carry such a dangerous weapon in a modern city. The man shouted " Javelin " and was presently admitted. Angus was puzzled. Perhaps they were all connected with security. His puzzlement grew when a huge man appeared with a steel ball in his hand. He shouted "Shot Putt" and walked past the official.
It suddenly dawned on Angus that these people were competitors. He opened his programme and sure enough under the heading "events" he saw the three words the men had said. Angus laughed to himself as a plan began to take shape in his mind. First he needed to buy one or two things.
An hour later he reappeared dressed in a tracksuit with "Scotland" written across the chest. Over his shoulder he carried a roll of barbed wire (铁丝网). Smiling to himself he walked up to the official and as casually as he could, shouted, "Fencing!"

1.
Which was Angus' new way of getting information about the outside world?
1. A.
  Travelling from his birthplace.
2. B.
  Listening to radio and watching TV.
3. C.
  Going to the nearby village to sell sheep.
4. D.
  Talking to hill-walkers in the region.

1. A.
  Olympic events.
2. B.
  Names of competitors.
3. C.
  Security weapons.
4. D.
  Names of countries.
3.
From the passage we can learn that ______.
1. A.
  more and more people went to Scotland to practise their English
2. B.
  the Spanish student's description of his country excited Angus
3. C.
  Angus had been planning a trip to Barcelona to see the Olympic Games
4. D.
  Angus became a member of the Scottish Olympic team
4.
From the passage we know that Angus seemed to be
1. A.
  poorly-informed
2. B.
  intelligent
3. C.
  strong-minded
4. D.
  athletic
5.
What do you expect the official would do in the end?
1. A.
  Help him carry the wire.
2. B.
  Refuse to let him in.
3. C.
  Give him a close inspection.
4. D.
  Lead him to the competition.
