Hurricane1 A hurricane（飓风）is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral（螺旋）around a relative calm center know as the“eye”.The“eye” is generally 20 to 30 miles wide,and the storm may ex- tend outward 400 miles. As a hurricane nears land,it can bring heavy rains,high winds,and storms（风暴潮）.The storm surges and heavy rains can lead to flooding.2 Hurricanes are given a different label,depending on where they occur. If they begin over the North Atlantic Ocean,the Caribbean Sea,the Gulf of Mexico,or the Northeast Pa-cific Ocean,they are called hurricanes.Similar storms that occur in the Northwest Pacific Ocean west of the International Date Line are called typhoon. Near Australia and in the India Ocean, they are referred to as tropical cyclones（龙卷风）.3 When a hurricane hits land,it can do great damage through its fierce winds,heavy rains , inland（内陆的）flooding, and huge waves crashing onto the shore. During a hurri-cane,homes,businesses,and public buildings may be damaged or destroyed;road and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harbour if they do not receive adequate warning.4 If a hurricane is coming in your area,the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one,stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors,because if the glass breaks it's real-ly dangerous. Do not be fooled if there is a lull（暂停）；it could be the eye of the storm-winds will pick up again.Paragraph 3_________A: What Should You Do During a Hurricane?B: What Are Different Names of Hurricanes?C: What Is a Hurricane?D: What Damages Can a Hurricane Cause?E: How Do You Know a Hurricane Is Coming?F: Where Do Hurricanes Usually Happen?

第二篇Hurricane（咫风）KatrinaA hurricane is a fiercely powertul , rotating（旋转的）form of tropical storm that can be 124 to 1,240 miles in diameter. The term hurricane is derived from Hurican,the name of a native American storm god.Hurricanes are typical of a calm central region of low pressure between 12 to 60 miles in diameter,known as the eye.They occur in tropical regions. Over its lifetime,one of these storms can release as much energy as 10,000 nuclear bombs.The seed for hurricane formation is a cluster（聚集）of thunderstorms over warm tropical waters.Hurricanes can only form and be fed when the sea-surface temperature exceeds 27℃ and the surrounding atmosphere is calm.These requirements are metbetween June and November in the northern part of the world.Under these conditions, large quantities of water evaporate（蒸发）and condense（冷凝）into clouds and rain-releasing heat in the process.It is this heat energy,combined with the rotation of the Earth,that drives a hurricane.When the warm column of air from the sea surface first begins to rise,it causes an area of low pressure.This in turn creates wind as air is drawn into the area.This spinning wind drags up more moist air from the sea surface in a process that strengthens the storm.Cold air falls back to the ocean surface through the eye and on the outside of the storm.Initially,when wind speeds reach 23 miles per hour,these mild,wet and grey weather systems are known as depressions,or low air pressure.Hurricane Katrina formed in this way over the south-eastern Bahamas on 23 August 2005.Katrina has had a devastating impact on the Gulf Coast of the US,leaving a disaster zone of 90,000 square miles in its wake（尾迹）一almost the size of the UK. Thousands have been killed or injured and more than half a million people have become homeless in a humanitarian（人道主义的）crisis of a scale not seen in the US since the Great Depression.The cost of the damage may top $100 billion.When the warm air from the sea surface begins to rise,itA:creates an area of low pressure.B:supplies cold air to the eye of a hurricane.C:increases the sea-surface temperature.D:strengthens the rotation of the earth.
