英语六级阅读备考：快速阅读练习(5)

　　One controversial study argues that the number of intense hurricanes worldwide has almost doubled over the past 35 years and it pins the blame on rising sea-surface temperatures. As the world warms, the amount of sea surface that exceeds the 27C required to spawn a hurricane will increase but a lot of other factors are also required for hurricanes to form, so experts are not sure what the future holds.

　　If hurricanes do become more frequent and intense, we might be able to find ways to mitigate their effects or even modify the weather. Possible methods include sending them off course, using water-absorbent powder to mop up clouds, coating the sea surface with fish oil or surfactants to stop warm water evaporating, and even zapping the colder streams of air in hurricanes and tornadoes with microwaves to disrupt their structure.

　　Questions:

　　1. According to the passage, both typhoons and cyclones are all hurricanesthey just appear in the different parts of the temperate zone.

　　2. The damaging power of each annual hurricane season changes about every ten years, but there is now evidence to suggest global warming could be the reason to make hurricanes strike more frequently and cause thousands of scientists attention.

　　3. Hurricane Katrina is the most destructive US natural disaster in living memory, causing damage estimated at $ 75 billion, killing or injuring thousands of people, making more than 500,000 people displaced, which has not been seen since the Great Depression.
