17.Illegally traded endangered species that escape,forming secondary populations,offer hope to their long-tem survival,a study suggests."This first came to my attention when I read a news story about the seizure of an illegal shipment of 23 yellow crested cockatoos(小葵花凤头鹦鹉),"said Luke Gibson,a college teacher.He learned that the species was critically endangered,which surprised him.This encouraged Dr.Gibson and his colleague to investigate(调查)how a critically endangered species had become self-sustaining outside of its natural range.They discovered 49 cases of a globally threatened species becoming established as a separate population,which they hadn't thought of,including the yellow-crested cockatoo in their city.
"This is a species which is primarily threatened by wildlife trade,"he told BBC News."Poachers(偷猎者)go out into the forest in its native range in eastern Indonesia and capture the bird and then ship them off,usually up to our city where there is a strong demand for pet birds.This is what has fueled the decline of this species in its native range.But it's really interesting because that same cause also had another effect:some of the people who were keeping this species here accidentally or intentionally released them."As a result of enough of the birds set free,it allowed a new self-sustaining population to be established in this city.
The government in of Dr.Gibson's city has made it illegal to capture the species,even though it is a non-native species.Because the city is affluent and relatively well educated,the cases of people breaking the law are extremely rare,explained Dr Gibson,unlike in its native range in Indonesia,where capturing birds forms a major source of income.
However,there can be downsides(缺点) to the newly established population of endangered species,such as a limited genetic pool,and suffering from novel diseases.It did also present a possible"very interesting"opportunity for conservationists,Dr.Gibson suggested.This would involve"harvesting"some of the newly established secondary population,which may provide a way to help slow global biodiversity loss.
32.What was beyond Gibson's expectations according to the first paragraph?C
A.The high rate of wildlife trade.
B.The preciousness of the birds.
C.The fact that the birds nearly disappear.
D.The news that the birds were poached.
33.What happened unexpectedly when the birds were shipped abroad?A
A.They formed a separate population.
B.They were kept as pet birds.
C.They were traded illegally.
D.They were killed for research.
34.Which can replace the underlined word"affluent"?B
A.Peace-loving
B.Rich
C.Free
D.Environment-friendly
35.For what purpose did the author write the passage?C
A.To appeal to everyone to stop the wildlife trade.
B.To explain the challenge the wild birds are facing.
C.To introduce a creative approach to wildlife conservation.
D.To raise people's awareness of protecting endangered species.

解答 32.C.细节理解题.根据第一段a college teacher.He learned that the species was critically endangered,which surprised him可知鸟类几乎消失的事实超出了他的预料;故选C.
33.A.细节理解题.根据第三段As a result of enough of the birds set free,it allowed a new self-sustaining population to be established in this city可知当鸟被运往国外时他们形成了一个独立的群体;故选A.
34.B.词义猜测题.根据文章Because the city is affluent and relatively well educated,the cases of people breaking the law are extremely rare,explained Dr Gibson,unlike in its native range in Indonesia,where capturing birds forms a major source of income可知因为城市是相对富裕和受过良好教育的,犯法的人的情况极为罕见,吉普森博士解释说,与在原产地在印度尼西亚,在那里捕捉鸟形式的收入主要来源;意为平和有爱的,富裕的;故选B.
35.C.推理判断题.根据文章This would involve"harvesting"some of the newly established secondary population,which may provide a way to help slow global biodiversity loss可知作者写这篇文章的目的是引进创造性的方法保护野生动物;故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
