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 |

The Antarctic Icecap is the largest supply of fresh water，representing nearly 2％of the world’s total of fresh and salt water. As can be seen from the table below, the amount of water in our atmosphere is over 10 times as much as the water in all the rivers taken together. The fresh water actually available for human use in lakes and rivers and the accessible ground water amount to only about one-third of 1％of the world’s total water supply.

Believing overweight among school children is the result of bake sales, the Education Department of New York declared that bake sales will be banned all through the states, as a part of their new “wellness”policy.
The ban gives a harder time to schools tying to earn money，because of budget difficulties. Bake sales have proven to be highly profitable toward schools with young people because the start-up costs are very small. Allie，a Roslyn High School freshman , agrees that bake sales are needed for school supplies.“l think it’s wrong for schools to ban bake sales because a lot of schools need the money to be raised. Our school could really use the money for new uniforms.”Allie also commented on the bake sales apparent cause of child overweight. “I feel that it is the student’s choice to eat the baked goods. lf they want it, let them have it．”Jessica，another Roslyn High School freshman, had a different opinion.“I feel that children can not always stay away from items such as cupcakes. It might be better if the amount of bake sales were limited, and only allowed students to buy one item.”
New York Education advisors are having trouble coming up with substitute product for students to sell. A plan of advertising healthier foods has come into play. However the department needs to consider if students will go for items like vegetables. Allie and Jessica don’t think so.“Students might not like the healthier foods. This way, the schools are gaining less money.”Allie shares. Another plan to think about is the idea of not selling food products altogether. Alternate programs are being conducted throughout New York schools，such as walk-a-thons, as a healthy way for students to earn money for their schools．The new “wellness”policy is declared in order to_______．
| A．help schools out of budget difficulties |
| B．reduce child overweight caused by bake food |
| C．help students save money spent on food |
| D．reduce the price of bake food sold in schools |
Which of the following statement about Allie is true?
| A．He is rich in experience about the bake sales at schoo1. |
| B．He agrees to carry out the bake sales ban at schools. |
| C．He attaches great importance to the school's income. |
| D．He attaches too much importance to students' health. |
According to Jessica, the cupcakes____________
| A．Don't belong to the bake sales | B．Should't be banned at school |
| C．Mustn't be sold at schools | D．can be fully replaced by vegetables |
Which is both healthy and profitable way for schools to earn money?
| A．The bake sales. | B．The vegetables sales |
| C．The walk-a-thons. | D．The food product sales． |
We can infer from the passage that schools in New York always______.
| A．sell baked food to students | B．free students to choose food |
| C．find ways to earn money | D．offer chances to earn money |
I remember my first Christmas party with Grandma．I remember the day when my big sister dropped the bomb: “There is no Santa Claus,” she laughed．“Even dummies know that!”
I fled to Grandma because I knew she always told me 21 ．After I told her everything, she said “No Santa Claus? Don’t believe it. Now, 22 your coat, and let’s go.”
“Go? Go where?” I asked．
“Where” 23 to be the General Store．As we walked through its doors, Grandma 24 me ten dollars．That was a lot in those days．“Take this money and buy something for 25 needs it．I’ll wait for you in the car．”
The store seemed big and 26 , full of people hurrying to finish their Christmas shopping．For a few moments I just stood there, 27 , holding that bill, wondering what to buy, and who on earth to buy it for．
Suddenly I thought of Bobbie who sat right behind me．I remembered he didn’t have a coat．I fingered the bill with growing 28 ．I would buy Bobbie a coat．
“Is this a Christmas present for someone?” the lady behind the 29 asked me kindly, as I laid my ten dollars down
“Yes,” I replied shyly．“It’s…for Bobbie.”
The nice lady smiled at me．I didn’t get any 30 , but she put the coat in a bag and wished me a Merry Christmas．
That evening, Grandma helped me 31 the coat and wrote, “To Bobby, From Santa Claus” on it．Then she 32 me over to Bobbie’s house．
Grandma parked down the street from Bobbie’s house, and she and I crept 33 and hid in the 34 ．Then Grandma gave me a sign．“All right, Santa Claus, get going．”
I took a deep 35 , dashed for his front door, threw the present down, pounded his doorbell and flew back to the safety．Together we 36 breathlessly in the darkness for the front door to open．Finally it 37 , and there stood Bobbie．
Forty years haven’t dimmed the thrill of those 38 spent shivering, beside my grandma, in Bobbie’s bushes． 39 , I realized: Santa was alive and well, and we were 40 his team．

The bar-tailed godwit(斑尾鹬) has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.
The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass(指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.For the flight from Alaska to New Zealand, the bar-tailed godwit _____.
| A．doesn’t need to stop to eat | B．is afraid of hot weather |
| C．seems very tired at last | D．should fly less than 7000 metres |
The main reason why the bar-tailed godwit can break the record is that it ______.
| A．eats little food every hour | B．has a special body shape |
| C．stores much water in its body | D．has very light body weight |
The last paragraph tells us that ________.
| A．researchers have understood the bird very well |
| B．the bird has a very good sense of direction |
| C．there are still many who doubt the bird’s ability |
| D．the bird has an inner compass |
What is the text mainly about?
| A．A bird that breaks the record for the longest non-stop flight. |
| B．Birds and airplanes that can fly over a long distance. |
| C．Reasons for the bar-tailed godwit’s long-distance flight. |
| D．An introduction to long-distance flights of birds and humans. |
