2、xtinction. Professor Carl Jones won the 2016 Indianapolis Prizethe highest accolade in the field of animal conservationfor his 40 years of work in Mauritius, where he saved an endangered kestrel from becoming the next Great Auk. When the 61-year-old first travelled to the east African island in the
3、1970s, he was told to close down a project to save the Mauritius kestrel. At the time there were just four left in the wild, making it the rarest bird on Earth. However, he stayed, using the techniques of captive breeding (人工繁殖), which involved snatching eggs from the birds nests and hatching(孵化)the
4、m under incubators, prompting the mothers to lay another set of eggs in the wild. A decade later, the number of Mauritius kestrels had soared to over 300 and today there are around 400 in the wild. The biologist has also been necessary in efforts to bring other rare species back from the edge of ext
5、inction, including the pink pigeon, echo parakeet and Rodrigues warbler. Prof. Jones was awarded the $250, 000 (172, 000) prize at a ceremony in London. “As a young man in my 20s, I certainly didnt enjoy the stress and the tension of the criticism I received, ” reflecting on the start of his career,
6、 he said the Mauritius kestrel project had been seen as a “dead loss” at the time. In the 1970s there was fierce opposition to the captive breeding techniques, with critics arguing that they were too risky and took the emphasis off breeding in the wild. Prof. Jones has devoted his whole life to his
7、work, only becoming a father for the first time eight years ago, at 53. He said receiving the prize was particularly important to him, because it proved that his work to save birds was right. 【文章大意】本文是一篇记叙文。文章介绍了生物学家Carl Jones通过人工繁殖的方式使濒临灭绝的鸟类的数量逐渐增加, 并且因此获得了2016年的印第安纳波利斯奖。1.

In the past, we knew the problem was there but we didnt know where t
17、o look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable. ”Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the babys parents! Thanks to data from the Int
18、ernational Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from
19、 other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7, 000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mices genes to those of patients.
