1.[D]根据文章第1段，老虎被捕杀是其数量剧减的根本原因，因此使老虎免于被杀是野生动物保护基金会的最终目的，故选D。

2.[B]第3段第2句说，但研究表明老虎捕捉猎物的成功率仅为1/20，B与之相符。第2段说到老虎一般会避免领土之争，C与之不符，故排除;A、D在原文中并未提及均可排除。

3.[A]第2段第2句提到，研究表明，一头雄老虎依年龄、体型及力量可以控制10至20公里的狩猎领地，随着老虎的长大，其体型及力量都在增大，其占领的狩猎领地的面积自然也就增大，故A正确。

4.[C]文章第4段首句说,许多人近来开始担心老虎项目过于成功，C项是该句的同义替换，故为答案。

5.[B]纵观全文，作者对于老虎保护项目没有加入个人的主观色彩，他持的是一种客观的态度，故选B。
