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.

Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered drivers to resist the temptation to take revenge (报复) on uncivilized behavior. On the other hand, a little politeness goes a long way towards reducing the tensions of driving. A friendly nod or a wave of appreciation in response to an act of politeness helps to create an atmosphere of goodwill and tolerance so necessary in modern traffic conditions. But such appreciation of politeness is too rare today. Many drivers nowadays don’t even seem able to recognize politeness when they see it.
However, misplaced politeness can be dangerous. Typical example are the drivers who brakes violently to allow a car to came out of a side street at some danger to following traffic; or the man who wave a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they like to.
An experienced driver, whose manners are faultless, told me it would help if motorists learnt to move correctly into traffic streams one at a time without causing the total blockages that give rise to bad temper. Unfortunately, modern motorists can’t even learn to drive, let alone master the less obvious points of driving perfectly. Years ago the experts warned us that an explosion in car-ownership would demand a lot more give and take from all road users. It’s high time for all of us to take this message to heart. According to the passage, the role of politeness can _______.
| A．help us learn about traffic rules |
| B．reduce the pleasure of driving |
| C．make our life happier than others’ |
| D．resist the temptation to take revenge on uncivilized behavior |
By “good sense” in the first paragraph, the writer means ________.
| A．the driver’s ability to understand politeness and react reasonably |
| B．the driver’s immediate response to terrible road conditions |
| C．the driver’s skill of controlling his or her car in extreme situations |
| D．the driver’s ability of driving safely in traffic jams |
Which of the following is NOT misplaced politeness?
| A．The driver lets old ladies cross the road when they want to. |
| B．The driver responses to an act of politeness in a friendly way. |
| C．The driver suddenly stops to permit a car to come from a side street. |
| D．The driver waves a child across a zebra crossing into the path of dangerous |
oncoming vehicles.In the writer’s opinion, ___________.
| A．strict traffic regulations are badly needed |
| B．drivers should apply road politeness properly |
| C．rude drivers should be punished |
| D．drivers should avoid traffic jams |
I’ve cheated in school when I thought that I could get away with it. I’m not proud of it and I don’t usually feel very good about myself afterwards, but sometimes it’s the only way possible to survive in a pressure cooker. My parents are really set on my getting good grades. They study my report card the same way they examine the newspaper’s stock market page. And they make me feel that I’ve got to live up to their expectations.
But often it’s like each teacher acts as if his is the only subject we have. They think nothing of piling on our homework or giving surprise quizzes. Sometimes we have to take two or three tests in different subjects on the same day. I’d like to see a lot of adults I know preparing for that.
When the pressure becomes too high, some kids may resort to (诉诸于) cheating. If you have three or four subjects to study for, you’re not going to be able to devote enough time to each subject in order to be well prepared for each class. Besides, it may be the only way left to live up to your parents’ expectations and compete with the top students in the class.
Everybody knows that if you cheat, it’s important not to get caught. Few things can cause more of chaos. Once, my elder brother got caught cheating on a math final. My parents acted as though he’d committed a federal crime. The assistant principal called them to school, but although the incident caused several conferences, I don’t think that anybody ever really understood what my brother was going through. We’re just supposed to perform outstandingly as well as always act honestly, but how many adults can actually live up to the standards they set for us?
My father has gotten countless traffic tickets for parking in no parking zones or for not coming to a full stop at stop signs. And you’ve always hearing about people who don’t file their incomes tax honestly. How about all the corruption in government? Successful adults often accept dishonesty in order to achieve their business goals. Are kids the only ones who are supposed to be perfect?
Most of my friends have cheated on tests in school at one time or another. The kids who never cheated are usually either afraid of getting caught or just don’t know how to do it safely. Nobody wants to cheat. But if it’s a choice of being honest or of getting a better grade, most kids will try for the latter. That may sound wrong, but we didn’t make the rules, we’re just trying to get by.What is the best title of this passage?
| A．Everyone can fight a cheat! |
| B．Everyone likes to cheat! |
| C．Cheating is reasonable! |
| D．No one wants to cheat! |
The author owes children’s cheat to the following EXPECT __________.
| A．parents | B．children | C．teacher | D．examinations |
In the fifth paragraph, the author mainly wants to say ____________.
| A．some adults can not live up to the standards they set for the children |
| B．kids are always supposed to be perfect |
| C．his father always cheats in his life |
| D．children shouldn’t learn from successful adults |
Which of the following is true according to this passage?
| A．The author thinks it is children’s right to cheat in school. |
| B．Most of the author’s friends like cheating on the tests in school. |
| C．The author thinks it wrong to cheat in school. |

Today we bring you an old tale. It’s the story of the three little pigs and the big bad wolf that blew down a house made of straw and one made of sticks. The only house left standing was the one made of bricks. Now there is new evidence to suggest that houses built with bales of straw can be very strong. They are also very environmental.
Pete Walker is a professor at the University of Bath in Britain. He and a team of researchers there have built a house made out of straw bales and hemp material. During the next twelve months the team will study the effectiveness of these materials in home building. Professor Walker says there are many good reasons for using straw.
Professor Walker: “One of the benefits is it’s a relatively inexpensive renewable material that’s readily available.” He also agrees that straw takes in carbon dioxide as it grows and helps the environment in other ways. So it can be seen as having no harmful effects on the environment.
Professor Walker: “The straw bale walls are relatively thick and so all that straw provides very good thermal insulation. So we make buildings that require very little heating in the winter or indeed very little cooling in the summer. So they require very little additional energy.”
Professor Walker says this reduces home operating expenses. It also reduces the effect on the environment. He says the current interest in straw bale houses is a direct response to the problem of climate change.
David Lanfear owns an eco-friendly home building service in the United States called Bale on Bale Construction. He says he laughed when some friends first told him about houses built of straw. But after doing his own research, he learned that building with straw bales made a lot of sense. He has now helped to build more than ten straw bale houses and says the building material is becoming more widely accepted.
To build the houses, he fills a wood frame with tightly packed bales of straw. Next he coats the walls inside and out with layers of clay plaster. He says the common ideas about straw houses continue, including stories about the threat of fire. Mr. Lanfear says straw bale houses have done well when tested for fire resistance. And he says his builders use the same building methods as traditional builders to keep out rain.
David Lanfear: “We use what we call good shoes and a good hat, and that would be a solid foundation and a really good roof.”What’s David Lanfear’s attitude towards the straw houses at last?
| A．Ridiculous. | B．Approving. |
| C．Defensive. | D．Unbelievable. |
What can we infer from the passage?
| A．Using straw to build houses is dearer than using bricks. |
| B．The houses built with bales of straw are stronger than those built with bricks. |
| C．Straw which is convenient to get is much cheaper than thick bricks. |
| D．Houses made of bricks are no better than those made of straw. |
According to the passage, we know that ________________.
| A．there is some experience in building the straw houses |
| B．the house made of straw bales is the same as the traditional one |
| C．the house made of straw bales is still under research |
| D．it’s uncertain that the straw house can be very strong |
