单选题
Hurricanes are violent storms that cause millions of dollars in property damage and take many lives. They can be extremely dangerous, and too often people underestimate their fury.
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.
单选题 The eye of the hurricane is ______ .
【正确答案】 C
【答案解析】[解析] 根据第三段倒数第二句话“The eye is a region of relative calm and clear skies in the center of the hurricane.”可知,风眼是在比较平静、天气晴朗的飓风中心地区。因此C项正确。
单选题 Which of the following statements is TRUE?
【正确答案】 C
【答案解析】[解析] A项不正确,根据最后一段倒数第三句话“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.”可知,storm surge是指水而不是风。B项不正确,根据最后一段开头的描述,飓风登陆时先在一个较大的可能范围内进行hurricane watch,然后在可能着陆点hurricane warning,可以看出hurricane warning比hurricane watch更严重。根据第三段最后一句“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.”,当风眼来临时人们如果走出房间会被风眼过去后的大风吹死,所以说在风眼来临时走出房间是不安全的,D也不正确。虽然文章中没有直接说,但通过排除法可以知道只有C是正确的。
单选题 Which of the following would be the best title for this passage?
【正确答案】 C
【答案解析】[解析] 本文围绕飓风的形成、飓风的预报、面对飓风的防范措施、飓风的消亡这几方面进行阐述,从总体来看,A、B、D都只涉及到文章的一个方面,只有C全面概括了文章的内容,因为文章主要是讲危险的飓风的。因此正确答案为C。
单选题 The low-lying areas refer to those regions that ______ .
【正确答案】 A
【答案解析】[解析] B、C两项是指一层平房,主要是强调房子低矮,而“low-lying areas”主要是指地势低平的地区,因此A项正确。
单选题 Which of the following is NOT a method of protecting one's house from a hurricane?
【正确答案】 C
【答案解析】[解析] 在飓风到来时的预防措施从原文第三段第六行“They should also try to hurricane-proof their houses by bringing in light-weight furniture and other items from outside and coveting windows.”可知,包括将轻的家具、物品带入房内,盖住窗户。这两项措施分别是选项B和D,但其中也暗含了选项C,因为将轻的物品放入房内也就意味着将重的物品带出房间,所以A也符合。只有C原文中根本未提及。
单选题 In the first sentence of last passage, the word "issue" can be best replaced with ______ .
【正确答案】 A
【答案解析】[解析] 本题考查对词语的理解。
