May 23 in 1981 was a big day for scientist Liu Yinzeng ( 刘荫增 ) . He and his team found seven wild crested ibises ( 朱鹮 ) in Hanzhong, Shanxi province.
“That night, I saw a crested ibis fly across the sky. We ran after it at once and found four adult crested ibises and three young little birds in the woods,” Liu said.
That was the start of China’s efforts to protect the birds. There are 4,400 crested ibises in China, making up most of the bird’s global ( 全球的 ) population of over 5,000. It has been more than 40 years since the birds came back.
Crested ibises are one of the oldest birds in the world. There were once lots of crested ibises in Asia. But in the 1960s, they began to disappear because of pollution and other human activities. That was why Liu and his team set out to look for the birds. They spent three years searching in 14 provinces before making their big finding.
Chinese scientists have worked hard to study and protect the birds since then. They have asked people not to hunt ( 捕猎 ) the birds, cut down trees, or use fertilizers ( 化肥 ) in the places where the birds live. They helped the birds have more babies. Some crested ibises were also sent to Japan and South Korea. All of these countries work together to protect the birds.
11 ． Seven wild crested ibises were found in 1981, by Liu Yinzeng and his team.
12 ． The number of wild crested ibises is over 5,000 in China.
13 ． There weren’t any crested ibises left before scientists found them in Hanzhong.
14 ． People are asked to improve the living environment of crested ibises.
15 ． Thanks to scientists’ efforts, crested ibises have avoided the danger of dying out.
答案
A 12 ． B 13 ． B 14 ． A 15 ． A
【导语】本文介绍刘荫增和他的团队对朱鹮的研究，呼吁人们保护这种鸟类。
11 ．细节理解题。根据 “May 23 in 1981 was a big day for scientist Liu Yinzeng ( 刘荫增 ) . He and his team found seven wild crested ibises ( 朱鹮 ) in Hanzhong, Shanxi province.” 可知， 1981 年 5 月 23 日，刘荫增他的团队发现了 7 只野生朱鹮。该项表述正确，故选 A 。
12 ．细节理解题。根据 “There are 4,400 crested ibises in China” 可知，中国有 4400 只朱鹮，该项表述错误，故选 B 。
13 ．细节理解题。根据 “But in the 1960s, they began to disappear because of pollution and other human activities. That was why Liu and his team set out to look for the birds. They spent three years searching in 14 provinces before making their big finding.” 可知，朱鹮没有灭绝，只是在 20 世纪 60 年代开始消失，该项表述错误，故选 B 。
14 ．细节理解题。根据 “They have asked people not to hunt ( 捕猎 ) the birds, cut down trees, or use fertilizers ( 化肥 ) in the places where the birds live.” 可知，他们要求人们不要在鸟类栖息的地方猎杀鸟类、砍伐树木或使用化肥。该项表述正确，故选 A 。
15 ．推理判断题。根据 “They helped the birds have more babies. Some crested ibises were also sent to Japan and South Korea. All of these countries work together to protect the birds.” 可知，它们帮助鸟类生育更多的孩子。一些朱鹭也被送往日本和韩国。所有这些国家共同努力保护鸟类。由此推知由于科学家的努力，朱鹮避免了灭绝的危险。该项表述正确，故选 A 。
