The project provided opportunities for researchers from India and abroad to study tigers in thereserves and gather previously unavailable information about their habits. Studies show thata male tiger may control a hunting territory of between 10 and 20 square kilometers,depending on its age, size and strength. Theterritory of male includes the smaller territories(領(lǐng)地) of three or four tigresses. A tiger marks the boundaries of its territories by spraying urineand other bodily liquids on bushes. But it tries to avoid territorial fights, being guided by thedistinctive body smell of other tigers. Tigers fight to death only when a tigress is defendingher young, or when a tiger is guarding a tigress from the attentions of other males.

　　The popular image of the tiger is that of a merciless and unconquerable hunter. But studiesshow that it catches only one of 20 victims it tries to attack.

　　Fears have recently developed that Project Tiger has been too successful. It has enabled thetiger population to double (by mid-80 S), but India"s human population has also grown outof control. Currently it is 750 million and likely to be 900 million by the end of the century.Land problem is becoming serious and many rural people feel bitter about the fact that somerich forests are reserved for tigers. A growing number of attacks by tigers on man has addedto the hostility .

　　答案詳解：

　　1.[D] 根據(jù)文章第1段，老虎被捕殺是其數(shù)量劇減的根本原因，因此使老虎免于被殺是野生動(dòng)物保護(hù)基金會(huì)的最終目的，故選D。

　　2.[B] 第3段第2句說，但研究表明老虎捕捉獵物的成功率僅為1/20，B與之相符。第2段說到老虎一般會(huì)避免領(lǐng)土之爭，C與之不符，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，一頭雄老虎依年齡、體型及力量可以控制10至20公里的狩獵領(lǐng)地，隨著老虎的長大，其體型及力量都在增大，其占領(lǐng)的狩獵領(lǐng)地的面積自然也就增大，故A正確。

　　4.[C] 文章第4段首句說,許多人近來開始擔(dān)心老虎項(xiàng)目過于成功，C項(xiàng)是該句的同義替換，故為答案。

　　5.[B] 縱觀全文，作者對于老虎保護(hù)項(xiàng)目沒有加入個(gè)人的主觀色彩，他持的是一種客觀的態(tài)度，故選B。
