　　Each year, 1,400 high-school students from more than 40 countries are invited to compete in the prestigious Intel International Science and Engineering Fair(Intel ISEF), the world’s largest precollege science contest．The select group of young scientists is chosen from the several million students who compete in local and regional science fairs throughout the year．Participants compete for ＄3 million in scholarships and prizes, presenting projects in 15 categories like medicine, biochemistry, computer science and zoology．Earning top honors isn’t the only goal for contestants．Nineteen percent(or 274)of the finalists at the 2005 competition held last month have already begun the process to patent their projects．

　　Ammem Abdulrasool, a senior at the Illinois Junior Academy of Science, won top honors at this year’s Intel ISEF for his project, “Prototype for Autonomy：Pathway for the Blind．” He walked away with ＄70,000 in prize money and a free trip to October’s Nobel Prize ceremony．Abdulrasool developed technology that allows visually impaired individuals to navigate themselves from one location to another by using the Global Positioning System．Individuals wear a half-kilo Walkman-size device, a bracelet on each arm and a pair of earphones．After entering a starting and ending location into a personal digital assistant(PDA), they are guided with verbal commands that tell them when and in what direction to turn．Simultaneously, a bracelet vibrates signaling the correct direction．To test his device, Abdulrasool recruited 36 blind adults and asked them to visit five landmarks in his neighborhood．The navigational tool saved people an average of 26 minutes in travel time and reduced the number of errors(wrong turns and missed locations)．“Looking at how hard it was for them to travel and how they were dependent on everyone else motivated me to do something,” he said．Abdulrasool hopes are applying for a patent and then plan to market the product commercially．

　　In the fair’s 56-year history, a number of projects have been implemented for commercial use．Michael Nyberg, a 2001 competitor, hoped to reduce the number of West Nile virus infections through acoustics．With a bucket of mosquito larvae and a sound generator, Nyberg discovered that a 24 kHz frequency resonated with the natural frequency of mosquitoes’ internal organs：larvae that absorbed the acoustic energy would explode．His sound-emitting device, Larvasonic, is now sold online(www．larvasonic．com)．Tiffany Clark, a 1999 competitor, found evidence that bacteria produced the methane gas found inside coal seams in Wyoming’s Powder River Basin．This suggested that injecting nutrients into coal seams might provide an unlimited supply of natural gas．A Denver-based technology firm is now continuing Clark’s high-school research．And someday soon, blind people around the world may be wearing bracelets that issue GPS commands．

　　In Europe, men do not usually wear skirts. But the Scottish national clothing for men is a kind of skirt. It is called a kilt. The Scottish like to be different. They are also proud of their country and its history, and they feel that the kilt is part of that history. That's why the men still wear kilts at traditional (傳統(tǒng)的) dances and on national holidays. They believe they are wearing the same clothes that Scottish men always used to wear.

　　That's what they believe. However, kilts are not really so old. Before 1730, Scottish men wore a long shirt and blanket around their shoulders. These clothes got in the way when the men started to work in factories. So, in 1730 a factory owner changed the blanket into a skirt; the kilt. That's how the first kilt was made.

　　Then, in the late 1700s Scottish soldiers in the British Army began to wear kilts. One reason for this was national sentiment ( = feelings) . The Scottish soldiers wanted to be different from the English soldiers. The British Army probably had a different reason. A Scottish soldier in a kilt was always easy to find! The Scottish soldier fought very hard and became famous. The kilt was part of the fame, and in the early 1800s men all around Scotland began to wear kilts.

　　These kilts had colorful stripes (條紋) going up and down and across. In the 1700s and early 1800s, the color of the stripes had no special meaning. Men sometimes owned kilts in several different colors. But later the colors became important to the Scottish families. By about 1850, most families had special colors for their kilts. For example, men from the Campbell family had kilts with green, yellow and blue stripes. Scottish people often believe that the colors of the kilts are part of their family history. In fact, each family just chose the color they liked best.

　　This is not the story you will hear today if you are in Scotland. Most Scottish people still believe that kilts are as old as Scotland and that the colors are as old as the Scottish families. Sometimes feelings are stronger than facts!

1．This text is mainly about ________.

A．soldiers' clothes in Britain
B．the history of Scotland
C．a(chǎn) special kind of skirt

[　　]

A．not part of the Scottish family history

　　A device that stops drivers from falling asleep at fine wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months．

　　The system, called Driver Alert, aims to reduce deadly road accidents by 20％－40％ that are caused by tiredness．Airline pilots can also use it to reduce the 30％ of all pilot-error accidents that are related to fatigue．

　　Driver Alert is based on a computerized wristband．The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey．After each sound the driver must respond by．squeezing the steering wheel(方向盤)．A sensor in the wristband detects this pressing action and measures the time between the sound, and the driver’s response．

　　Tiredness is directly related to a driver’s response time．Usually, a watchful driver would take about 400 milliseconds to respond but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy．

　　In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest．If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible．

　　The device has been delivered to the department’s 1aboatories for testing．If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year．

　　Most animals have little connection with animals of a different kind, unless they hunt them for food．Sometimes, however, two kinds of animals come together in a partnership which does good to both of them．You may have noticed some birds sitting on the backs of sheep．This is not because they want a ride, but because they find easy food in the parasites(寄生蟲)on sheep．The sheep allow the birds to do so because they remove the cause of discomfort．So although they can manage without each other, they do better together．

　　Sometimes an animal has a plant partner．This relationship develops until the two partners cannot manage without each other．This is so in the coral(珊瑚)of the sea．In their skins they have tiny plants which act as " dustmen", taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe．If the plants are killed, or are even prevented from light so that they cannot live normally, the corals will die．

(1)

Some birds like to sit on a sheep because ________．

[　　]

A．

閱讀理解。
　Force other than damaging winds are also at work inside tornadoes (龍卷風(fēng)). Sometimes, as the turning,
jumping funnel (漏斗) passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside.
This explosion (爆炸) is caused by the low air pressure at the center of a tornado. 　　
    The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house
the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch
between the inside and outside pressure may not seem like much. But suppose a tornado funnel passes over
a small building that measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of
pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up
to an unbalanced pressure of 57,600 pounds. The pressure on the four walls adds up to 172,800 pounds. 　　
    If windows are open in the building, some of the inside air will rush out through them. This will balance
the pressure inside and outside the building. But if the windows are shut tightly, the great inside pressure may
cause the building to burst. 　　
    Unfortunately, heavy rain happens in thunderstorms that later produce tornadoes. So, people often shut all
windows to protect their property. This may cause far worse damage later.
1. Which of the following is the main topic of the passage?
[     ]
A. Where tornadoes are formed. 　　
B. When tornadoes usually occur. 　　
C. How tornadoes can be prevented. 　　
D. Why tornadoes cause so much damage.
2. According to the passage, tornadoes can destroy building because the _____.
[     ]
A. force of a tornado increases the air pressure in a building 　　
B. air pressure at the center of a tornado is over 172,000 pounds 　　
C. weight of a tornado can crush a building's roof when it passes overhead 　　
D. air pressure inside a tornado is less than the air pressure inside a building
3. According to the passage, the pressure on a building during a tornado can be reduced by _____.
[     ]
A. closing the windows 　　　　　
B. opening the windows 　　
C. using an electric fan 　　　　
D. making the roof and walls stronger
