          How young com辦zrs (美洲獅) leam to hunt is one of the things cougar researchers like Mark Elbroch are working hard to figure out. “We know nothing about their secret lives' Elbroch says. He and his team track cougars deep in the Wyoming wilderness.

          An adult called F51 was one of the cougars they kept (標(biāo)簽) on —they followed her using the satellite signal from her electronic collar. One fall when Elbroch discovered that F51 had given birth to four kittens — three females and a male —he put expandable tracking collars on them too,so he could follow them as they grew.

          About one week after they were bom,their eyes opened. Their fur was thick enough to blanket them from the oncoming cold winter. Their brown and black spots could mix with the forest,helping to keep them safe from (食肉動(dòng)物) .

          By the time they were five weeks old the four kittens were restless to leave their home. They'd  still be nursed for another month,but they were ready to go out of their hideaway with their mother. They began to learn their way around Mom's territory(領(lǐng)地). As they grew older and stronger,they learned how to search for food by following their mother,watching her select an animal to approach,and observing how she caught the animal.

          While they were only a few weeks old,Mom would tell her kittens to hide when she hunted. Sometimes she has to travel a couple of miles to find'meal. “The minute she makes the kill,she hides it and heads back for the kittens,and they follow her to the kill site,” Elbroch says.

          But the kittens learned that sometimes meal plans change quickly. In February and March,wolves chased F51 and her kittens away from six different kills. During the cold winter,one kitten disappeared” probably a victim of wolves,and another didn^，t survive the bitterly cold weather.

          Luckily F51 was able to provide plenty of food for her two remaining kittens. She shares her territory with another female,and they are friendly with each other. F5Ts kittens have learned that cooperation is a choice. “We have seen females get together and share food”’Elbroch says. “F51 spent three or four months sharing almost every kill with an unrelated female and her kittens."

A篇(自然)

本文是記敘文。文章講述了一只成年美洲獅與其幼崽的生存法則。

1. D. 細(xì)節(jié)理解題。由第一段中的How young cougars learn to hunt is one of the things cougar researchers …及第二段中的 he put expandable tracking collars on them too,so he could follow them as they grew可知，給美洲獅幼崽脖子上佩戴項(xiàng)圈是為了觀察它們?nèi)绾螌W(xué)習(xí)捕獵，也就是如何掌握生存技能的。

2. A. 推理判斷題。由第三段中的Their brown and black spots could mix with the forest,helping to keep them safe from predators可知，這些棕黑色的斑點(diǎn)與森林的顏色融合，可以保護(hù)美洲獅免受其他食肉動(dòng)物的襲擊。.

3. D. 詞義猜測(cè)題。由劃線詞下文中的 They'd still be nursed for another month,but they were ready to go out of their hideaway with their mother 可知，這些美洲獅幼崽應(yīng)該是“急切地”想出去捕獵。

4. B. 細(xì)節(jié)理解題。由倒數(shù)第三段中的 The minute she makes the kill,she hides it and heads back for the kittens,and they follow her to the kill site 可知，F(xiàn)51捕到獵物后，會(huì)叫來(lái)自己的孩子們一起分享食物。

5. C. 主旨大意題。本文主要講述了美洲獅在森林里與不同的對(duì)手抗衡捕獵的過(guò)程，由此可以推斷文章主要描述了它們的堅(jiān)毅。
