Question

3．Thousands of dead red-winged blackbirds fell from the sky in an Arkansas town on New Year's Eve after massive injuries，tests by Arkansas officials concluded on Monday．Some 5，000birds mysteriously fell from the sky in Beebe，Arkansas after dark on New Year's Eve．"The birds suffered from acute physical injuries leading to internal hemorrhage（大量出血） and death．There was no sign of infectious disease，"the Arkansas Game and Fish Commission said in a statement．The birds were otherwise healthy，it said．
One theory is that birds were frightened by New Year's fireworks and flew into buildings or other objects．"Loud noises were reported shortly before the birds began to fall from the sky，"the statement said，adding that blackbirds have poor night vision and seldom fly at night．
Another theory was that severe weather such as lightning accounted for the loud noises but this was  discountedbecause the violent weather had already left the area．"We're leaning more toward a stress event，"said Arkansas Game and Fish Commission spokesman Keith Stephens．
The commission also is trying to determine what caused the deaths of up to 100，000fish over a 20-mile stretch of the Arkansas River near a dam in Ozark，125miles west of Beebe．The fish were discovered on December 30．Stephens said the commission expected results on the fish tests in probably a month．Since almost all the fish were one species--bottom-feeding drum，Stephens said，the test was very important．Stephens also said："The events do not appear related．"Both that section of the river and the air at the site of the bird deaths were tested for toxins（毒素）．Beebe is a town of about 4，500people located 30miles northeast of the state capital．

57．What is NOT the probable reason why the dead red-winged blackbirds fell from the sky？D
A．Internal hemorrhage  B．Fireworks
C．Lightning weather    D．Murder

Answer 1

分析 文章大意：本文講的是數(shù)千只紅翅膀的黑鳥從天上掉落下來，后來當(dāng)?shù)毓賳T分析了其中的原因．

解答 57．D 細(xì)節(jié)理解題．根據(jù)文章第一段第三句．"The birds suffered from acute physical injuries leading to internal hemorrhage（大量出血） and death．There was no sign of infectious disease，"可知A項(xiàng)表述正確；根據(jù)第二段內(nèi)容One theory is that birds were frightened by New Year's fireworks and flew into buildings or other objects．"Loud noises were reported shortly before the birds began to fall from the sky，"the statement said，adding that blackbirds have poor night vision and seldom fly at night可知B項(xiàng)表述正確；根據(jù)第三段第一句話Another theory was that severe weather such as lightning accounted for the loud noises可知C項(xiàng)表述正確，而文中沒有提到是這些鳥是被謀殺，因此D項(xiàng)是錯誤的．
58．B 猜測詞義題． 根據(jù)文章第三段第一句話Another theory was that severe weather such as lightning accounted for the loud noises but this was discountedbecause the violent weather had already left the area可知 discount意為"不可信的"，與B項(xiàng)意思一致．
59．C 推理判斷題．根據(jù)文章最后一段最后一句話The events do not appear related．"Both that section of the river and the air at the site of the bird deaths were tested for toxins（毒素）可知這些魚的生存的環(huán)境收到了污染，因此他們?nèi)旧狭思膊《�死去．因此答案選C．
60．A 通過整體內(nèi)容分析，本文首先列出了一個問題，然后對這個問題出現(xiàn)的原因作了分析，因此作者的寫作思路就是通過分析原因進(jìn)一步展開的．因此答案選A．
