Questions are based on the following passage．
It was a hurricane season almost without hurricanes. There were just two: Humbertoand Ingrid， and both were relatively weak Category 1 storms. That made the 2013 Atlantichurricane season， which ended Saturday， the least active in more than 30 years——forreasons that remain puzzling.
Heading into the hurricane season， all signs pointed toward a very active one.Forecast teams predicted seven to nine hurricanes， with higher-than-average ACE （累积气象学中用于衡量飓风强度指数的指标） . Only the European Center for
Medium-Range Weather Forecasting predicted about 80 percent of average ACE， but itstill said there would be six or seven hurricanes.
Why was this season so inactive？ What did the forecasts miss？ Although there aresome hypotheses， it is not entirely clear， but in the meantime， there are some potentialexplanations.
Major signals such as the E1 Nino Southern Oscillation （ENSO）， surface pressureand sea-surface temperature all pointed to an average to above-average season. But therewere some possible suppressing factors.
Even over the long three-month window of August to October， the vast majority ofthe tropical Atlantic was dominated by drier-than-normal air， especially in the deeptropics off the coast of Africa. Dry air can quickly weaken or dissipate a tropical cyclone （热带气旋） ， or inhibit its formation.
The average temperature profile in the region was less conducive to thunderstormgrowth and development during the core months， which means that the amount of risingair in the region may have been reduced as well.
Tropical waves， the embryos of many tropical cyclones， have their origins overcontinental Africa. A persistent feature called the African easterly jet stream （东非东风急流 ） ——a fast-moving river of air in the low and middle levels of the atmosphere——extendsfrom Ethiopia westward into the tropical Atlantic Ocean. It breaks down into discretewaves， and every few days another wave leaves the coast. Some are barely noticeable，while others become tropical storms.
During the height of the hurricane season， most tropical cyclones form. fromdisturbances off the coast of Africa.
Winds in the jet normally cruise along at 20 to 25 mph at an altitude of 10，000 feetfrom August to October， but this year they were about 12 to 17 mph weaker. One would expectthat to have a big impact on the amplitude （振幅 ） of easterly waves and the hurricaneseason.
How was the season"s inactivity related to climate change？ It"s not accurate toassociate any particular season with climate change. The reason is that intra- and inter-seasonal variability is so large that any subtle signals of influence from climate change areoverwhelmed.
What did the signs predict before the hurricane season came？ 查看材料
A.There would be more hurricanes this year than average.
B.There would be no hurricanes at all this year.
C.There would be fewer hurricanes this year than before.
D.There would be another active hurricane season.
Hurricanes normally originate as a small area of thunderstorms over the Atlantic Ocean west of the Cape Verde Islands during August or September. For several days, the area of the storm increases and the air pressure falls slowly. A center of low pressure forms, and winds begin to whirl around it. It is blown westward, increasing in size and strength.
Hurricane hunters then fly out to the storm in order to determine its size and intensity and to track its direction. They drop instruments for recording temperature, air pressure, and humidity (湿度), into the storm. They also look at the size of waves on the ocean, the clouds, and the eye of the storm. The eye is a region of relative calm and clear skies in the center of the hurricane. People often lose their lives by leaving shelter when the eye has arrived, only to be caught in tremendous winds again when the eye has passed.
once the forecasters have determined that it is likely the hurricane will reach shore, they issue a hurricane watch for a large, general area that may be in the path of the storm. Later, when the probable point of landfall is clearer, they will issue a hurricane warning for a somewhat more limited area. People in these areas are wise to stock up on nonperishable foods, flash light and radio batteries, candles, and other items they may need if electricity and water are not available after the stoma. They should also try to hurricane-proof their houses by bringing in light-weight furniture and other items from outside and covering windows. People living in low-lying areas are wise to evacuate their houses because of the storm surge, which is a large rush of water that may come ashore with the storm. Hurricanes generally lose power slowly while traveling over land, but many move out to sea, gather up force again, and return to land. As they move toward the north, they generally lose their identity as hurricanes.
The eye of the hurricane is ______ .
A.the powerful center of the storm
B.the part that determines its direction
C.the relatively calm center of the storm
D.the center of low pressure
听力原文： Weather scientists call hurricanes by names to make clear which storm they are talking about. An Australian weather scientist began giving women's names to storms before the end of the nineteenth century. Weather scientists used the names of their girlfriends or wives for storms during World War Two. (33) The United States weather service started officially using women's names for storms in nineteen fifty-three. In nineteen seventy-eight, it began including men's names as well.
(34) Today, scientists make up lists of names years in advance, They agree on them at meetings of the concerned organization. The lists include both American and international names.
The United States National Hurricane Center near Miami, Florida, watches for the development of storms. It gives a name to each one that reaches a wind speed of sixty-two kilometers an hour. A different list of names is used each year. The first name begins with the letter "A". The second begins with "B" and so on. The same list will not be used again for at least six years. The names of storms that have caused extremely severe damage may be retired at the request of the country that was affected. That name will not be used again for at least ten years. (35) This is done to avoid legal problems or confusion. It may be reasonable that the United States asks that the name Katrina be retired.
