     It is possible that in 50 years the only tigers in the world will be in zoos. One

hundred years ago there were  maybe 100,000 tigers in the world. Today scientists are not sure how many are left, as it is difficult to count them. There rnay be only between 5,000 and 7,000 tigers in the world.

      Tigers are only found in Asia. Already they have disappeared from many

countries. There are no longer any Caspian(黑海的) tigers in Central Asia. They have died out in the two  islands  of Java (爪哇 ) and Bali (巴里) . The situation in some

parts of Asia is also very serious. There are perhaps only 100 Chinese tigers left. In

eastern Russia, the number is a little higher. There are about 450 tigers left. On the

island of Sumatra (苏门答腊) , which has many thick forests , there are maybe 500

tigers.

      Why has the number fallen so quickly? The first reason is that tigers are

meat-eaters. They need a lot of land to find enough food. Also they live in forests and many of these have been cut down. At one time, tiger shooting was a sport ,

especially in India. Local(当地的) people some- times kill tigers because they kill their cows. The other reason is that dead tigers are used for Traditional Chinese Medicine. All parts of the body are used, including the bones and whiskers (须) . People who

take TCM think chat these medicines will make them live longer.

      How can we protect the tigers that are left? First, some wildlife parks have been

created. In these reserves (自然保护区 ) ,local people may not kill tigers and the

forests may not be cut down. And 145 countries have agreed to stop selling tiger

parts for medicine. With luck , the tigers can be protected in the few areas of the

world where they still live.

2. Why arc there fewer tigers today?

(四)阅读《心态收获命运》一文,完成15—17 题。(10 分)

  ①面对同样的景色,心境不同,感受各异。对于失意者、失恋者、失去亲人或遭受不幸的人来说,他们感受不到风光的宜人之处。这个时候,一曲哀伤的音乐更能引起他的共鸣,更切合此时他心境的需要,能够缓解伤痛,排遣内心的郁闷。

  ②面对同样的境遇,态度不同,结果迥然。当事业遭受挫折、生活艰难不堪、人生处于低谷时,悲观脆弱者,要么自暴自弃,一蹶不振,要么低头认输,境况越来越糟;而乐观豁达、直面人生者,能把平凡的日子过得精彩,能把沉重的生活变得轻松,能把苦难的体验变得生动,能够不断去开辟人生的新境界,享受生活赋予的一切酸甜苦辣,从而真正去感受人生的真谛和生命的意义。

  ③当然,生活对每个人来说确实是不公平的。但是,如何对待生活却给予了我们公平自由的权利。

  ④人生不如意的时候很多。面对生活,关键是看我们以什么样的心态去对待。心态不同,人生的境况也大不同。《阿甘正传》片尾有句话:“人生就如同一片轻盈的羽毛,有落下的时候,而你应该鼓舞自己让他不断飘扬而上,向着新的高度超越自我”。

  ⑤ “塞翁失马,焉知非福。”时刻告诫自己,保持一颗平常心,保持一颗平和乐观的心态。相信吃亏未必不是福,失去了的未必就是我们真正需要的,失去的未必就永远得不到的。何必要拘泥于一时之得失,何必要斤斤计较,何必要自陷于痛苦的深渊不能自拔。

  ⑥人生风光无限。走过一座山峰,迎来的可能是更加雄奇壮美的景色。人生何尝不是这样,有时看似糟糕透顶的事情后面,往往带给我们意想不到的快乐结局。

⑦有什么样的心态,往往就会有什么样的命运。只要我们直面生活,傲视不幸,笑对痛苦,就一定能攥紧命运的缰绳,活出不一样的人生。
