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 goods and services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they bought. The thieves then go shopping with your card number — or sell the information over the Internet.
Computers hackers have broken down security systems, raising questions about the safety of cardholder information. Several months ago,25 000 cust
omers of CD Universe, an on-line music retailer(批发商),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 f
or 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-card 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 with https:// — the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.
Keep your password safe: Most online sites require a user name and password be
fore placing an order. Treat your passwords with care.What do most people worry about the Internet according to this passage?

Shundagarh is a village on India's east-facing coast.It is a village of simple mud and grass houses built on the beach just above the waterline.The Khadra Hills rise immediately behind the village,to a height of one hundred and fifty meters.A simple,good-hearted old man,whose name was Jalpur,farmed two small fields on the very edge of these hills.From his fields he could see the fishing boats that travelled up and down the coast.He could see the children playing on the sands;their mothers washing clothes on the flat stones where the Shiva River flowed into the sea;and their fathers landing the latest catch or repairing nets and telling stories that had no end.
All Jalpur owned in the world were the clothes he wore day in and day out,the miserable hut(小屋) that he slept in at night,a few tools and cooking pots—and his fields.The corn that he grew was all that made life possible.If the weather was kind and the harvest was good,Jalpur could live happily enough—not well,but happily.When the sun was fierce,and there was little or no rain,then he came close to the line between life and death.
Last year the weather had been so kind,and the harvest promised to be so good,that Jalpur had been wondering whether he could sell all that he had and live with his son farther up the coast.He had been thinking about doing this for some years.It was his dearest wish to spend his last days with his son and his wife.But he would go only if he could give;he would not go if it meant taking food out of the mouths of his grandchildren.He would rather die hungry than do this.
On the day when Jalpur decided that he would harvest his corn,sell it,and move up the coast,he looked out to sea and saw a huge wave,several kilometers out,advancing on the coast and on the village of Shundagarh.Within ten minutes everyone in Shundagarh would be drowned.Jalpur would have shouted,but the people were too far away to hear.He would have run down the hill,but he was too old to run.He was prepared to do anything to save the people of Shundagarh,so he did the only thing that he could do: he set fire to his corn.In a matter of seconds the flames were rising high and smoke was rising higher.Within a minute the people of Shundagarh were racing up the hill to see what had happened.There,in the middle of his blackened cornfield,they found Jalpur;and there they buried him.
On his grave,they wrote the words: Here lies Jalpur,a man who gave,living: a man who died,giving.Which of the following could Jalpur NOT see from his Fields?
| A．Mothers washing clothes. |
| B．Fathers taking their corn to market. |
| C．Fishing boats traveling on the sea. |
| D．Children playing on the sands. |
Why didn't Jalpur live well?
| A．He didn't work hard. |
| B．He had too many children to feed. |
| C．He only depended on good weather and harvest for survival. |
| D．The villagers kept taking his corn. |
Jalpur's dearest wish was to _________.
| A．move away from his son |
| B．take a vacation up the coast |
| C．make a great deal of money in order to live an easy life |
| D．spend his last days with his son and his wife |
What did Jalpur do when he saw the huge wave?
| A．He set his corn on fire so the people of Shundagarh would leave the beach. |
| B．He screamed loudly to get the villagers' attention. |
| C．He ran down the hill to tell the people. |
| D．He stood still,not knowing what to do. |
Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(无意识的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called “secret messages to ourselves ”.According to the passage,Elias Howe was_________.
| A．the first person we know of who solved problems in his sleep |
| B．much more hard-working than other inventors |
| C．the first person to design a sewing machine that really worked |
| D．the only person at the time who knew the value of dreams |
The problem Howe was trying to solve was_________.
| A．what kind of thread to use |
| B．how to design a needle which would not break |
| C．where to put the needle |
| D．how to prevent the thread from getting caught around the needle |
Thomas Edison is spoken of because_________.
| A．he also tried to invent a sewing machine |
| B．he got some of his ideas from dreams |
| C．he was one of Howe's best friends |
| D．he also had difficulty in falling asleep |
Dreams are sometimes called “secret messages to ourselves” because _________.
| A．strange images are used to communicate ideas |
| B．images which have no meaning are used |
| C．we can never understand the real meaning |
| D．only specially trained people can understand them |
We know that many animals do not stay in one place.Birds,fish and other animals move from one place to another at a certain time.They move for different reasons:most of them move to find food more easily,but others move to get away from places that are too crowded.
When cold weather comes,many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration（迁移）is probably the migration of fish,which is called “Salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old,it returns to its birthplace in fresh water.Then it gives birth and dies there.In northern Europe,there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside,and many of them are killed when they fall into the sea.
Recently,scientists have studied the migration of a kind of lobster（龙虾）.Every year,when the season of bad weather arrives,the lobsters get into a long time and start to walk across the floor of the ocean.Nobody knows why they do this,and nobody knows where they go.
So,sometimes we know why humans and animals move from one place to another,but at other times we don’t.Maybe living things just like to travel.Most animals move from one place to another at a certain time to _________.
| A．give birth | B．enjoy warmer water |
| C．find food more easily | D．find beautiful places |
The mice in northern Europe move when _________.
| A．they give birth | B．the weather is bad |
| C．the place gets too crowded | D．they haven’t enough food |
The lobsters move _________.
| A．to the fresh water | B．to the deeper sea |
| C．at a certain time | D．to find more food |
Watch a baby between six and nine months old,and you will observe the basic idea of geometry（几何学）being learned.Once the baby has mastered the idea that space is three dimensional（空间的）,it reaches out and begins grasping various things,that the ideas of sets and numbers are formed.So far,so good.But now an ominous development takes place.The nerver fibers in the brain separate themselves in such a way that the baby begins to hear sounds very exactly.Soon it picks up language.And it is then brought into direct communication with grown-ups.From this point on,it is usually downhill all the way for mathematics,because the child now becomes exposed to all the rubbish words and beliefs of the born.Nature,having done very well by the child to this point,having permitted it the luxury（奢侈）of thinking for itself for eighteen months,now gives it up to the unreasonable conventions（惯例）and beliefs of society.But at least the child knows something of geometry and peaceful days,no matter what vicissitudes（兴衰变迁）it may suffer later on.The main reservoir of mathematical ability in any society is thus possessed by children who are about two years old,children who have just learned to speak freely.What does the passage mainly discuss?
| A．The impact（影响）of language on mathematics. |
| B．Children’s ability to learn languages. |
| C．How basic ideas of physics are learned? |
| D．Maths-learning strategies（策略）for babies. |
According to the passage,which of the following activities would teach a baby about geometry?
| A．Picking up a wooden block. | B．Recognizing the number 2. |
| C．Saying a rubbish word. | D．Looking at a distant word. |
Which of the following conclusions is true according to the writer?
| A．The language ideas used in early education interrupt mathematical reasoning. |
| B．It is hopeless to try to teach children mathematics after the age of two. |
| C．Language teaching should join some mathematical formulas（公式）. |
| D．Preschool education should emphasize society’s beliefs and conventions. |
Healthy knees aren’t the main consideration in choosing high heels,but new research says chunky heels are just as bad for the knees as spindly stilettos（细高跟鞋）.“It takes a long time to feel the effects of knee osteoarthritis（骨关节炎）—and once you do it,it is too late,”said Dr.Casey Kerrigan,leading researcher of the study and associate professor at Harvard Medical School’s department of physical medicine.“I compare it to smoking—one cigarette is not painful,but over a lifetime it is.Wide-heeled shoes feel comfortable,so women wear them all day long,”Kerrigan said.“They are better for your feet than stiletto heels,but just as bad for your knees.”
In the study,researchers had twenty women wear two pairs of shoes with three-inch heels,one with a narrow heel and the other with a thick one.The scientists compared how much pressure was put on the women’s knees by both types of shoes.The women also walked bare-foot to test normal pressure.The scientists found that both types of shoes applied equal amounts of pressure to the knees.Compared with walking barefoot,the heels increased pressure on the inside of the knee by 26 percent.Increased pressure on the knee eventually leads to arthritis,experts say.
The idea that high heels are bad for your health isn’t new—scientists have warned women for years that they contribute to problems ranging from corns to hammer toes,tendonitis,knee pain,sprained(扭伤)ankles and back problems.But in 1998,Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis,a painful joint disease that destroys cartilage(软骨)surrounding the knee.The first study looked only at stiletto heels,and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.“This study confirms what we all intuitively（直觉地）know that high-heeled shoes of any kind are not good for our health,”said Dr.Glem Pfeffer,a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.We learn from the passage that women choose chunky heels because _________.
| A．they want to walk comfortably |
| B．chunky heeled shoes are cheaper than stiletto heeled pairs |
| C．chunky heels do less harm to knees |
| D．chunky heels are not painful at all |
The study mentioned in the second paragraph found that _________.
| A．pressure on the foot is caused by high heels |
| B．the pressure is abnormal while walking barefoot |
| C．arthritis is always caused by pressure on the knees |
| D．both types of shoes have the same harm to the knees |
It can be inferred from the passage that _________.
| A．people got to know the high heels are bad for health recently |
| B．people have known the high heels are bad for health for years |
| C．people haven’t known the high heels are bad for health yet |
| D．people will be warned that the high heels are bad for health soon |
Kerrigan’s late study looked at the chunky high-heeled shoes because _________.
| A．they feel more comfortable |
| B．they are related to knee osteoarthritis |
| C．they are worn by many women |
| D．they are different from stiletto heels |
The best title for the passage may be _________.
| A．Talking Healthy Knees into Consideration |
| B．High-heels Do Harm to Knees |
| C．Chunky Heels and Stiletto Heels |
| D．When Wearing High-heels |
