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.

What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively a short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity(容量). As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring a physical change too: the head, in particular the forehead, will grow larger.
Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over long period of time it is likely that man’s eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and motions similar to our own.The passage mainly tells us that __________.
| A．Man’s life will be different in the future |
| B．Future man will look quite different from us |
| C．Man is growing taller and uglier as time passes |
| D．Man’s organs’ functions will change |
What serves as the evidence that man is changing?
| A．Man has got stronger eyes now than he ever had. |
| B．Man’s hair is getting thinner and thinner. |
| C．Man’s arms and legs have become lighter and weaker. |
| D．Man has been growing taller over the past 500 years. |
The change in man’s size of the forehead is probably because __________.
| A．he makes use of only 20% of the brain’s capacity |
| B．his brain has grown larger over the past centuries |
| C．he will use his brain more and more as time goes on |
| D．the other 80% of his brain will grow in due time |
Which of the following is TRUE about a human being in the future?
| A．He is hairless because hair is no longer useful. |
| B．He has smaller eyes and wears better glasses. |
| C．His fingers grow weaker because he doesn’t have to make use of them. |
| D．He thinks and feels in a different way. |
It is implied that __________.
| A．human beings will become less attractive in the future |
| B．body organs will become poorer if they are not used often |
| C．human beings hope for a change in the future life |
| D．future life is always predictable |
February has long been a month of romance. With the sweet smell of roses in the air, romantic films hit cinemas and love stories fill newspapers and magazines.
On the 14th day, it is a custom for a boy to take his girlfriend out to dinner, buy her flowers and chocolates, write poems, sing to her or even spell out her name with rose petals! This is what you see on Valentine’s Day, a day named after Valentine who was a priest(牧师) in the third century Rome. When the emperor (皇帝) decided that single men could become better soldiers than those with wives, he didn’t allow marriage.
But Valentine continued to perform marriage ceremonies for young lovers in secret. When his actions were discovered, the emperor sentenced him to death. While in prison, it is said that Valentine fell in love with the daughter of his prison guard. Before his death, he wrote her a letter, which he signed “From your Valentine”, an expression that is still in use today. Valentine died for what he believed in and so he was made a Saint (圣徒), as well as becoming one of history’s most romantic characters.
Nowadays, Valentine’s Day is also popular among Chinese young people. Some students are planning to make Valentine’s cards for parents, teachers and friends. Others want to hold parties at which they will exchange small gifts and eat heart-shaped cakes. The idea is to have fun and encourage people to share in the spirit of St. Valentine.Why did the emperor in Rome not allow marriage in his country?

A 7.0 magnitude（级）earthquake killed more than 230,000 people in Haiti. Then an 8.8 magnitude quake killed more than 900 people in Chile. And few weeks later, a 6.0 magnitude quake struck rural eastern Turkey, killing at least 57 people.
The earthquakes kept coming hard and fast. 1It’s not. The problem is what’s happening above ground, not underground, experts say.
2They’re rapidly putting up buildings that can’t stand up to earth quakes, scientists believe.
And news reports and better earthquake monitoring make it seem as if earth quakes are increasing all the time.
On average, there are 134 earthquakes a year that have a magnitude between 6.0 and 6.9. So far this year there have been 40 earthquakes—more than in most years for that time period. But that’s because the 8.8 quake in Chile caused a large number of strong aftershocks.
Also, it’s not the number of quakes, but their destructive effects that gain attention. The death is largely due to building standards, 3Paul Earle, a US seismologist, called for better building standards in the world’s big cities.
Of the 130 cities worldwide with populations of more than I million, more than half are likely to be hit by earthquakes. 4“If you have a problem feeding yourself, you’re not really going to worry about earthquakes,” said Paul.
The earthquakes made everyone start to think 5“People are paying attention to the violent planet we’re always lived on. Come back an another six moths if there has been no earthquakes, most people will have forgotten it again,” said US disaster researcher Dennis Mileti.
| A．But it won’t last. B．More people are moving into big cities. C．Earthquakes don’t kill people, buildings do. D．There have been more deaths overt the past decade from earthquakes. E．Many people began to wonder if something terrible is happening underground. F．While it seems as if the are more earthquakes occurring, there really aren’t. G．But developing nations with growing populations don’t pay attention to earthquake preparedness. |
Time and how we experience it have always puzzled us．Physicists have created fascinating theories, but their time is measured by a pendulum （钟摆） and is not psychological time, which leaps with little regard to the clock or calendar．As some-one who understood the distinction observed, "When you sit with a nice girl for two hours it seems like a minute, but when you sit on a hot stove, a minute seems like two hours．"
Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age．They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass．For example, a day at the office flies compared with a day at the beach．Since most of us spend fewer days at the beach and more at the office as we age, an increase in structured tune could well be to blame for why time seems to speed up as we grow older．
Expectation and familiarity also make time seem to flow more rapidly．Almost all of us have had the experience of driving somewhere we’ve never been before. Surrounded by unfamiliar scenery, with no real idea of when we’ll arrive, we experience the trip as lasting a long time. But the return trip, although exactly as long, seems to take far less time. The novelty of the outward journey has become routine. Thus taking a different route on occasions can often help slow the clock.
When was become as identical as identical as beads（小珠子）on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day—to stop time, so to speak.
Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems so full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn’t have to be.The underlined sentence in Paragraph 1 is used to show.
| A．psychological time is quite puzzling |
| B．time should not be measured by a pendulum |
| C．physical time is different from psychological time |
| D．physical theory has nothing to do with the true sense of time |
Why do units of time fly faster as we grow older?
| A．Our sense of time changes. |
| B．We spend less time at the beach. |
| C．More time is structured and scheduled. |
| D．Time is structured with too many appointments. |
In Paragraph 3 “novelty” probably means.
| A．excitement | B．unfamiliarity | C．imagination | D．amusement |
The purpose of the passage is to.
| A．give various explanations about time |
| B．describe how we experience time psychologically |
| C．show the different ideas of physicists and psychologists on time |
| D．explain why time flies and how to slow it down psychologically |
I live in the land of Disney, Hollywood and year - round sun．You may think People ,n such an attractive, fun - filled place are happier than others．If so you have some mistaken ideas about the nature of happiness．
Many intelligent people still think fun equals happiness．The truth is that fun and happiness have little or nothing in common．Fun is what we experience during an act．Happiness is what we experience after an act．It is a deep, long-lasting emotion．
Going to an amusement park or a ball game, watching a movie or television are fun activities that help us relax, temporally forget our problems and maybe even laugh．But they do not bring happiness, because their positive effects end when the fun ends．
I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun．They have constant access to exciting parties, fancy cars, expensive homes, everything that spells "happiness" But in memoir（回忆录） after memoir, they expose Ac unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages and loneliness．
Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying．If he is honest, he will tell you that he is afraid of making a commitment．For commitment is in fact quite painful．The single life is filled with fun, adventure and excitement．Marriage has such moments, but they are not its most distinguishing features．
Similarly, couples that choose not to have children are deciding in favor of painless fun over painful happiness．They can dine out whenever they want and sleep as late as they want．Couples with babies are lucky to get a whole night' s sleep．I don't know any parent who would choose the word fun to describe raising children．
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations we can ever come to．It liberates time: now we can devote more hours to activities that can truly increase our happiness．It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless．And it frees us from envy: we now understand that all those rich and famous people we were so sure are happy because they are always having so much fun actually may not be happy at all．What is the passage mainly about?
| A．Fun and happiness． |
| B．Success and satisfaction． |
| C．Marriage and commitment． |
| D．Entertainment and responsibility． |
The author probably agrees that ____．
| A．fun creates long - lasting satisfaction |

What does the author think of marriage?
A．It ends in pain．
