　　小题1:B

　　小题2:C

　　小题3:B

　　小题4:C

　　小题1:细节推理题。根据第1段wheretheyhadbeenlookedafterbyzookeepers及…unoccupiedbytheirkindfor50years可知放生地是原先这些鹦鹉曾生活的但已有50年没有同类鹦鹉生存的地方，应选择B。

　　小题2:推理判断题。根据第1段的描述，将这些鹦鹉放生到它们原先生活的地方，但它们却不能适应这些环境了，应选择C。A“能找到返回泽西的路”，B“不能认出自己的父母”，D“能生产新的品种”都不合文章本意。

　　小题3:细节理解题。根据第4段Researchonparrotsisvitalfortworeasons.…weneedtobeawareofwhatthebirdsmustknowiftheyaretosurviveintheirnaturalhome.可知对鹦鹉研究的重要性首先体现在需要了解更多怎样让鹦鹉在野生地生活的常识。选项B符合所提问题。其它选项都不符合文意。

　　小题4:推理判断题。根据最后一段notattempttodiscouragethepractice,butratherurges…可知不提倡将鹦鹉作为宠物饲养。
