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
Computer viruses are ________.
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. to destroy data B. to commit crimes
C. to commit mischief D. to create confusion

They leap from helicopters or speeding boats, bringing aid to swimmers who get into trouble off Italy’s popular beaches.
For these dog lifeguards, the doggie paddle (狗刨式游法)does just fine.
These “l(fā)ifedogs” tow a buoy(救生衣) that victims can grab, or a raft they can sit on to be towed back to shore, and unlike their human counterparts(與對(duì)方地位相當(dāng)?shù)娜?, they can easily jump from helicopters and speeding boats to reach swimmers in trouble.
With millions flocking(人群) to Italy’s crowded beaches each summer, the Italian Coast Guard says it rescues about 3,000 people every year — and their dog helpers are credited with saving several lives.
It takes three years for the canines to reach expert rescue status, and currently 300 dogs are fully trained for duty, said Roberto Gasbarri, who co-ordinates the Italian School of Canine Lifeguards program at a centre outside of Rome in the seaside town of Civitavecchia.
“Dogs are useful in containing the physical fatigue(疲勞) of the lifeguard, to increase the speed at which casualties(遇難者) are retrieved(找到并銜回), to increase the security of both the casualty and of the lifeguard,” Gasbarri said.
The Civitavecchia centre is one of a dozen around the country for the school founded more than 20 years ago in the northern province of Bergamo by Ferruccio Pilenga, whose first trainee was his own Newfoundland.
The school will train any breed(品種), as long as they weigh at least 30 kilograms, but Labradors, Newfoundlands and golden retrievers are most commonly used because of their natural instinct for swimming. Each dog works in tandem with(同 ……合作) a human lifeguard, who also acts as the animal’s trainer.
Which of the following can act as the best title fo the passage?
A. Dogs to the Rescue B. Dogs Are Good at Doggie Paddle
C. The Wonderful Performance of Dogs D. Dogs: Our Loyal Friends
What advantage do these life-dogs have over human lifeguards in a rescue?
A. Dog can swim very fast B. Dogs can finish rescue work with ease.
C. Dogs can finish the great work free of charge. D. Dogs can easily be trained
Which of the following is TRUE about the Civitavecchia center according to the text?
A. Any breed can be trained there.
B. The ones who have the gift for swimming are welcomed.
C. After a better training, the dogs can work alone.
D. It is the only place for training dog lifeguards in the school.
What does the writer want to tell us in the 4th paragraph?
A. Without the dog lifeguards, 3,000 people would lose their lives every year.

At a certain time in our lives we consider every place as the possible sites(地點(diǎn)) for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices.
The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I gave for it.
The real attractiong of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相鄰) on one side by the river, and separated from the highway by a wide field. The poor condition fo the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apples trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.
I was not really troubled by the loss. I had always had a garden, but I don’t thing I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted (無(wú)牽掛的). It makes but little difference whether you own a farm or not.
【小題1】What do we know about the author?
A.He wanted to buy the oldest farm near where he lived. |
B.He made a study of many farms before buying. |
C.He made money by buying and selling farms. |
D.He had the money to buy the best farm in the country. |
A.It was of good market value. |
B.It was next to the highway. |
C.It was in a good position. |
D.It was behind a nice garden. |
A.He was afraid the owner might changes his mind. |
B.He hoped to enlarge the forest on the farm. |
C.He wanted to keep the farm as it was. |
D.He was eager to become a farm owner. |
A.the money the author lost in buying the farm |
B.the sale of the garden in the Hollowell place |
C.the removal of the trees around the house |

“I Went Skydiving at 84!”
As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of a woman to do that. I got a taste of that dream in 2011,when my husband arranged for me me ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time ,I told my husband that I wanted to skydive. So when our retirement community(社區(qū))announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.
In the essay, I wrote about my desire to skydive, stating George Brush Sr. did it at age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that I was one of the winners. I just couldn’t believe it.
One june 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn’t frightened—I was really just looking forward to the experience. When we reachen 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute(降落傘), then we just floated downward fo zhout five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt—much better than the hot air ballon. I was just enjoying it.
Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don’t stop living just because you are 84 years old. If there’s something you want to experience, look into it. If it’s something that is possible, make it happen.
