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,
theclouds, 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 storm. 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 ______.
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
【正确答案】
C
【答案解析】[解析] 本题的四个选项中，只有C项为正确答案。这从文中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"可以推出，即风眼是在比较平静、天气晴朗的飓风中心地区。
单选题
Which of the following statements is true? ______.
A.A storm surge is a dramatic increase in wind velocity.
B.A hurricane watch is more serious than a hurricane warning.
C.Falling air pressure is an indicator that the storm is increasing in
intensity.
D.It is safe to go outside once the eye has arrived.
【正确答案】
C
【答案解析】[解析] 本题的四个选项中，只有C项为正确答案。从文中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，因此A项错误；根据最后一段开头的描述，飓风可能登陆时先在一个较大的可能范围内进行hurricane watch，然后可能在着陆点hurricane warning，由此可以看出hurricane warning比hurricane watch更严重，因此B项错误；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"可知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，因此D错误。

______.
单选题
Which of the following is NOT a method of protecting one's house from a
hurricane?
A.Taking out heavy things.
B.Moving in light-weight furniture.
C.Equipping the house with stones.
D.Covering windows.
【正确答案】
C
【答案解析】[解析] 本题的四个选项中，只有C项文中未曾提及。这可以文中第四段第四句"They should also try to hurricane-proof their houses by bringing in light-weight furniture and other items from outside and covering windows"推出，即将轻的家具、物品带人房内，盖住窗户，而将轻的物品放入房内也就意味着将重的物品搬出房间。
