After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe’s hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15.
Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: “Your computer is now stoned. Legalize marijuana. ” (Regardless of your politics, you don’t want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated—no trading disks, no on-line communication—or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?—as in, pay me $1 million or my virus will destroy your system.
In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened—an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike—on the artist’s birthday.The much-feared M-day was ________.
| A．Friday-the-13th when the eponymous virus was due to strike |
| B．Friday-the-15th when the Maltese Amoeba would be activated |
| C．the previous Friday when Michelangelo virus was due to strike |
| D．the previous Friday which coincided with the artist's birthday |

| A．diseases spread from one computer to another by shared disks |
| B．viruses hidden in a computer’s instructions by the designers |
| C．little time bombs hidden in a computer waiting to be triggered |
| D．just those computer programs created by malevolent designers |
Which of the following sayings fits the Michelangelo virus?
| A．A burnt child dreads the fire. | B．The bug’s bark was worse than its bite. |
| C．A barking dog seldom bites. | D．Once bitten, twice shy. |
The author implies that in days to come the viruses might be used ________.

A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt-water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol（胆固醇）levels.In which section of a newspaper can we read this passage?
| A．Ads | B．Movies |
| C．Briefs | D．Health and Diet |
The passage is mainly about _________.
| A．the high incidence of heart disease in some countries |
| B．the changes in people’s diet |
| C．the effect of fish eating on people’s health |
| D．the daily fish consumption of people in different cultures |
The phrase “this relationship” in paragraph 6 refers to the connection between ____ and the level of heart disease.
| A．the amount of fish eaten | B．regular fish-eating |
| C．the kind of fish eaten | D．people of different areas |
From the passage we know the author is most probably ___________.
| A．a heart doctor | B．a science researcher |
| C．a supporter of healthy eating | D．a university student |
Woman Uses Daughter's Key to "Steal" Car
Charlie Vansant, a college student of Athens, Ohio who reported that his car was stolen, got a surprise when he learned a woman had mistaken it for her daughter's car and taken it－using her key.
Kate Anderson became an accidental car thief when picking up her daughter's car near an Ohio University building last week. Anderson spotted the Toyota Camry（丰田凯美瑞）and used her daughter's key to unlock the car, start the engine and drive home-without realizing that the car wasn't her daughter's.
When Charlie Vansant left class a short time later, he found only an empty parking spot. He first assumed the car had been towed, but when the police couldn't find a record of it, they took a theft report.
The morning after Anderson took the car, her daughter discovered the Camry in the driveway wasn't hers. Anderson said she was able to find Vansant's name on paperwork in the glove compartment and look up his phone number on the website for the university.
When Anderson told Charlie the car was in her driveway, "It sounded real suspicious at first, as she wanted to hold the thing for ransom（赎金）,” said Vansant. He eventually went to the house with a police officer, where he was reunited with his car. According to the police report, the case was closed "because of mistaken car identity", Anderson wasn't charged.
Vansant seemed to blame the car company more than the "thief". "Her key fit not only my lock, but my ignition（点火装置） as well - so high-five for Toyota. I guess." he said.What does the underlined word "towed" mean in paragraph 3?
| A．removed. | B．damaged. |

| C．Charlie had thought he had to give Anderson money to get his car back. |
| D．Mrs. Anderson used her daughter's key to unlock Charlie's car and drive home. |
What does Charlie mean by "high-five for Toyota"?
| A．He is blaming Toyota for the poor quality of car keys. |
| B．He should thank Toyota for returning his car. |
| C．He wants to celebrate with Toyota for getting his car back. |
| D．He thinks highly of Toyota for producing large quantities of cars. |
What is likely to happen next according to the passage?
| A．Mrs. Anderson was charged with stealing a car. |

We each have a unique genetic(基因的, 遗传的)make-up. Every cell of our body has the same set of about 100, 000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of our skin to the way our brain works. We have one of several billion combinations of DNA which come from the random mixing of our parents’ genes. Except for identical twins(同卵双胞胎), no one has the same combination as another person. We are unique! We are unique in another way, too: in the way we are raised and all the experiences we have from before birth to adult life. These experiences influence us, our behaviour and attitudes, and the choices we make.
But are genes or life experiences more important in shaping our appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births—some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.
Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit(继承). For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.
Scientists are trying to identify the different genes that influence our behavior. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.
We could ask, “Are our lives determined by our genes or our upbringing? ”Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.What is the main idea of the first paragraph?
| A．Both our genes and our experiences make us who we are. |
| B．How we turn out depends on our parents’ genes. |
| C．Everyone has a physical double somewhere in the world. |
| D．We cannot easily change our physical appearance. |
Why are scientists studying twins?
| A．To find out how many twins are born every year. |
| B．To discover what shapes us as individuals. |
| C．To compare differences between twins. |
| D．To study brother-and-sister relationships. |
According to the passage, .
| A．one in 70 twins are genetically identical |
| B．non-identical twins are usually not of the same sex |
| C．twins separated at birth behave exactly the same |
| D．identical twins are genetically the same |
What does the underlined word “this” in Paragraph 4 refer to?
| A．Our love of sports. | B．Our attitude to risk-taking. |
| C．Our skill at bungee jumping. | D．Our ability to take drugs. |
Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.
Some scientists believe that birds do sing some of the time just because they are happy. However they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.
Do you know what a ‘territory’ is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.
If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting（筑巢）season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.
You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.Some scientists believe that most of the time bird’s singing is actually________.
| A．an expression of happiness | B．a way of warning |
| C．an expression of anger | D．a way of greeting |
What does the underlined word “territory’’ mean?
| A．A place where families of other species are not accepted |
| B．A place where a bird may shout at the top of its voice |
| C．An area for which birds fight against each other |
| D．An area which a bird considers to be its own |
Why do birds keep on singing at nesting season?
| A．Because they want to invite more friends |
| B．Because their singing helps frighten outsiders away |
| C．Because they want to find outsiders around |
| D．Because their singing helps get rid of their fears |
How does the writer explain bird’s singing?
| A．By comparing birds with human beings |
| B．By reporting experiment results |
| C．By describing birds’ daily life |
| D．By telling a bird’s story |

One Tuesday evening in the beginning of the fall 1996 semester (学期) at Shippensburg University, sirens sounded. These sirens were not in celebration; they were a cry to the university that something was wrong. A house, only one block away, was on fire. Nine of the university’s students lived there.
From the minute the word got out that help was needed, it seemed like everyone showed up. The victims (受灾者) of the fire were offered endless invitations for housing for the night. The very next day, everyone got into gear to do their part in helping them. Flyers(传单) were posted with items that were immediately needed, just to get these students through this next couple of days. Boxes for donations (捐赠品) and money jars were placed in every residence hall (学生宿舍)．
As a residence director, I went before the students in my hall to ask them to do what they could. I knew that college students don’t have much, but I asked them to do their best: “Every little bit will help.” I really didn’t think they could do much. I was proved wrong.
At the hall council meeting the night after the fire, my residents decided to have a wing competition, where each wing of the building would team up to see who could bring in the most donations. I announced that the wing who won would receive a free pizza party.
Thursday evening we announced over the PA system that we were beginning the wing competition. Within minutes, the place exploded. The single large box that I had placed in the lobby (大厅) was overflowing. We quickly grabbed more boxes, and we watched in amazement as they, too, filled to the brim(边；沿). Members of the resident assistant staff and I began to count the items. I was astonished by what I saw, and I was inspired by these kids.
When we came to the final tally(得分), the winners turned to me and announced that they would like to donate their winnings as well. They wanted the victims of the fire to have their pizza party.
Tears welled up in my eyes. I had watched these students jump to action, work tirelessly and donate all that they could. And then, as if that were not enough, they handed over their reward. I was touched and so very proud of them.The writer mainly wanted to________ by the story.
| A．tell us nine of the college students suffered from a fire |
| B．sing praise of the college students helping the victims selflessly |
| C．describe how successful the wing competition was |
