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. 小题1: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

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小题3: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.小题4:The author implies that in days to come the viruses might be used ________.

  • Several years ago, while attending a communication course, I experienced a most unusual process. The instructor asked us to list _\_1__ in our past that we felt _\_2__ of, regretted, or incomplete about and read our lists aloud.

    “Nearly 20 years later, Sheriff Brown’s name _\_13__ on my list. I didn’t even know if he was still _\__14___. Last weekend, I dialed the information in my hometown and found there was a Roger Brown still listed. I tried his number. After a few ___15___, I heard, “Hello?” I said, “Sheriff Brown?” Paused. “Yes.” “Well, this is Jimmy Calkins.”
    “And I want you to know that I did it?”Paused. “I knew it!” he yelled back. We had a good laugh and a _\_16__ discussion. His closing words were: “Jimmy, I always felt bad for you _\_17__ your buddies got it off their chest, but you were carrying it _\_18__ all these years. I want to thank you for calling me...for your sake.”
    Jimmy inspired me to _\_19__ all 101 items on my list within two years, and I always remember what I learned from the course: It’s never too late to _\__20___the past wrongdoings.

  • Puppies for Sale 待售的小狗 A store owner was putting a sign above his door that read “Puppies For Sale”. Signs like that have a way of  1 small children, and  2 enough, a little boy appeared under the store owner’s sign. “  3 are you going to sell the puppies for?” he asked. The store owner replied, “Anywhere from $30   4 $ 50.” The little boy  5 in his pocket and pulled out some  6 . “I have $ 2.37,” he said. “  7 I please look at them?” The store owner  8 and whistled and out of the kennel (狗窝) came a lady, who ran down the aisle (过道) of his store  9 by five puppies.

The little boy became  13 “That’s the little puppy that I want to buy.” The store owner said, “No, you don’t want to buy that little dog.

He is  17 going to be able to jump and play with you like the other puppies.” To his surprise, the little boy reached  18 and rolled up his pant leg to show a badly twisted, crippled (残疾的) left leg  19 by a big metal brace (支架). He looked up at the store owner and softly replied, “Well, I don’t run so well myself, and the little puppy will need someone who  20 !”

  • What happens to mother-daughter relationships when girls become teenagers. It seems that girls go from playing “dress up”, to arguing with their mothers about how they should dress. When a girl is 3-4 years old they love to “dress up” in their mothers’ clothes, put on their mothers’ makeup, cook, and do whatever else their mother does. This is the time when she can be classified as being a mama’s girl. How come girls change so much from childhood to the teenage years? Many parents seek the answer when their daughter becomes a teen. Often when a girl enters high school her behavior changes as well as her physical appearance. When I was young I always liked playing “dress up”. It made me feel older and more like my mother. Even when I entered middle school, I still depended a lot on my mother to choose and buy my clothes. Once I entered high school there was a big change. To me, my mother’s clothes were no longer “in fashion”, and neither was her opinion. I started becoming interested in boys and tried to improve the way I looked. It was not that I wanted to look cool, I just wanted to look my age. This is the time that the mother-daughter relationship can take a turn. It’s difficult for a mother to know that her daughter is no longer totally dependent on her. When the daughter starts wearing revealing clothing, dating, and just wanting to be more independent, a mother starts to feel left out, or not needed. The number of arguments increases, and the number of times when the mother and daughter get along happily decreases. When these things start to happen, it is a sign that the daughter wants her independence and the freedom to grow up. When you notice how much your relationship had changed, try to believe positive things come out of the change. Put all the negatives aside and concentrate on what your mother is feeling instead of just on what you’re feeling. When it seems too hard to handle, take some quiet time and write out your feelings. Maybe at another time, you can share them with your mother and try to find a way to better your relationship as mother and daughter. If you don’t feel comfortable sharing your feelings, at least write them down so you can get them out. It’s better than keeping them bottled up inside. 小题1:The girls would argue with their mothers because ________.

    A.they need more independence

    B.mothers want daughters to be mama’s girls again

    C.they think their mothers’ clothes are no longer in fashion

    D.all of the above小题2:From the passage, we know that ________.

    A.the teenage period is a sensitive part in human life

    B.the parents can’t get the answer why their daughters change a lot

    C.they can get on well only in talking, no matter what mothers or daughters do

    D.mothers should concentrate on their own feelings小题3:A “mama’s girl” will Not________.

    A.dress up in her mother’s clothes

    B.depend a lot on her mother to choose and buy her clothes

    C.like wearing revealing clothing

    D.think her mother’s clothes are in fashion小题4:When the daughter starts wanting to be more independent, ________.

    A.a mother starts to feel left out

    B.it is the time when mother and daughter get on joyfully increases

    C.she wants to look cool

    D.All of the above

  • Surfing—the art of riding a wave on a pointed board—is the wildest, fastest natural water sport known to man. In recent years, it has developed into a major sport around the world, from Australia to South Africa. Australians brave(挑战) men—eating sharks to ride the green waves Down Under, Hawaiian experts risk(冒…之险) their lives on huge, thirty foot swells(浪涛) against the wind of Oahu; Californians of all ages go out the year-round. In the winter, surf-riders put on life-suits to ride grave waves so cold that their flesh turns blue. Surfing is no sport for weak persons. Swimming a quarter of a mile or more, and pushing a surfboard out to where the swells are just right for riding, can be real work. Then, at exactly the right moment, you climb up the wave and go fast across the face of a powerful swell with the white water jumping at your feet. The huge wave bites at your shoulder, threatening(威胁) at any moment to smash your flat. In the next several seconds, a cool head and lightning—quick action back to the pressure of the attacking wave will bring your board under control for that great ride down the back of the great, green mountain of water. Once on the beach, you know why surfing is growing in popularity as an international sport, and you’re glad to be a member of this new water world. 小题1:The first paragraph mainly tells us ______.

    A.people around the world go surfing all the year round

    B.the definition(定义) of the sport

    C.how to surf in the sea

    D.where to surf around the world小题2:The author believes that surfing _______.

    A.is not an easy sport

    B.can be done by anyone

    C.should be done by everyone

    D.does not require courage小题3:In order to experience what real surfing is, _______.

    A.you must first swim a quarter of a mile to warm your body

    B.you will first ride on a board to reach the swells

    C.you must first put on your life-suits before doing surfing

    D.you must first swim to the swells with your board

  • When I was about 12, I had an enemy, a girl who liked to point out my shortcomings.
    Week by week her list grew: I was very thin; I wasn’t a good student; I talked too much; I was too proud and so on.. I tried to bear all these all these things as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
    He listened to me quietly, then he asked, “Are the things she said true or not? Janet, didn’t you ever wonder what you are really like? Well, you now have the girl’s opinion. Go and make a list of everything she said mark the points that are true. Pay no attention to other things she said.”
    I did as he told me. To my great surprise, I discovered that about half of the things were true.
    some of them I couldn’t change (like being very thin), but a good number I could and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.
    I brought the list back to Daddy. He refused to take it, “That’s just for you,” he said. “ You know better than anyone else, the truth about yourself. But you have to learn to listen, not just closing your ears anger and feeling hurt . When something said about you is true, you’ll find it will be of help to you. Don’t shut your ears. Listen to other people’s opinions, but hear the truth and do you know is right thing to do.”
    Daddy’s advice returned to me at many important moments. IN my life, I’ve never had a better piece of advice.
    小题1:Which do you think would be the best title for this passage?
    A Not an Enemy, but a Best Friend
    B The Best Advice I’ve Ever Had
    C My Father
    D My Childhood
    小题2:What does “ week by week her list grew” mean?
    A Week by Week, my shortcomings grew more serious.
    B She had made a list of shortcomings and kept on adding new ones to it so that it was growing longer and longer.
    C I was having more and more shortcomings as time went on.
    D Week by week she discovered more shortcomings of mine and point them out.
    小题3:Why did her father listen to her quietly?
    A Because he believed that what her daughter’s enemy said was mostly true.
    B Because he had been so angry with his daughter’s shortcomings that he wanted to show this by keeping silent for a while.
    C Because he knew that his daughter would not listen to him at that moment.
    D Because he wasn’t quite sure which girl was telling the truth.
    小题4: What did the father do after he heard his daughter’s complaint?
    A He told her not pay any attention to what her “enemy” said
    B He criticized her and told her to overcome her shortcomings.
    C He told her to write down all that her “enemy” had said about her and pay attention only to the things that were true.
    D He refused to take the list and have a look at it.
