问题 Listen to the following passage. Write a short English summary of around 150-200 words of what you have heard. You will hear the passage only once and then you will have 25 minutes to finish your English summary. This part of the test carries 2O points. You may need to scribble a few notes in order to write your summary satisfactorily.  
Call them twisters or tornadoes. They’re nature’s most violent storms with swirling winds that can top 300 miles per hour. About 800 twisters sweep through the US every year, more than anywhere else in the world. The hardest-hit area is a swath of the Great Plains from Texas to South Dakota known as Tornado Alley.
    Here warm air flows up from the Gulf of Mexico in the spring and summer and crashes into cold air pushing down from Canada. The meeting produces violent thunderstorms called supercells. Scientists don’t completely understand how or when tornadoes form. But they do know a supercell like this one can produce a twister if the conditions are right.
    As warm moist air flows into a storm, it gets pushed up and twisted by upper level winds. As this rotating column of air gathers force, conditions are right for a collision below. When rain cooled downdrafts, hit warm air near the ground, a low hanging revolving cloud forms beneath the cell. A tornado is imminent.
    Tornadoes don’t last long, anywhere from twenty seconds to an hour, but it can take years to recover from the devastation. These storms kill nearly 90 people each year in the US and cause millions of dollars worth of damage. When a tornado is spotted, experts advise going to a basement staying away from any windows or climbing into a first floor bathtub. While most people run for safety when a twister appears, some scientists actually race to meet it.
    These storm chasers hunt down tornadoes trying to get right in the twister’s path. They en- counter incredible cloud movement, torrential rain, severe winds and hail, lightning and breath- taking storm structures. When they finally locate a twister, they measure it using special tools. These scientists hope to someday predict exactly when and where tornadoes will strike. Little can prevent the damage caused by tornadoes, but better forecasting could save more lives giving survivors the chance to rebuild after living through one of the most violent storms on earth.

答案     Twisters or tornadoes are nature’s most violent storms with swirling winds that can top 300 miles per hour. The US has the most twisters in the world with about 800 twisters every year. The hardest-hit area is a swath of the Great Plains from Texas to South Dakota known as Tornado Alley.
    When warm air flows up from the Gulf of Mexico in the spring and summer and crashes into cold air pushing down from Canada, the meeting produces violent thunderstorms called supercells. Scientists hold that a supercell like this is likely to produce a twister, although they don’t completely understand how or when tornadoes form.
    Tornadoes last from twenty seconds to an hour, but it can take years to recover from the devastation. These storms kill nearly 90 people each year in the US and cause millions of dollars worth of damage. In case of a tornado, experts advise going to a basement staying away from any windows or climbing into a first floor bathtub.
    Some scientists hunt down tornadoes trying to get right in the twister, s path. They encounter incredibly severe conditions to measure the twister with special tools. These scientists hope to someday predict exactly when and where tornadoes will strike. Thus more lives can be saved by the forecast.
