1 In a remote national park on Australiasmost southwestern tip, a lone radio tower standsabove a quiet wetland. Every five seconds, it collectssignals from a few dozen young tortoiseshiding out beneath the glassy waters. The tinytortoises don't journey far, but researchers aretracking their every move. The fate of a species—one of the most endangered in the world—might depend on these data.

2 There are fewer than 70 adult western swamp tortoises living in the wild in twosmall wetland reserves north of Australia. These spots are all that remains of the creatures' native habitat, and they are drying out, owing to rising temperatures and a reductionin rainfall. So, in August last year, scientists selected 41 baby tortoises from a breeding programmein a zoo and released them into this national park, some 330 kilometres south ofwhere the tortoises are naturally found. The aim is to see whether the animals can toleratecooler climates, and whether this new habitat might ensure the species' future as the planetwarms.

3 This experiment is part of a series of closely monitored field trials testing one of themost controversial strategies for saving a species—a concept called assisted migration. Thetortoise is thought to be the first vertebrate (脊椎動物) to be moved beyond its historicalrange because of climate change.

4 Nicki Mitchell, a zoologist at the University of Western Australia, is leading the projectthat is trying to save the tortoise. Her team is now on their fourth trial of releasing bredtortoises into selected wetlands to test the potential of assisted migration. It's a high?risk strategy—and one that researchers have long debated.“ It's a demonstration project forthe world, and we particularly want to make sure there are no bad outcomes,” Mitchellsays.

5 Conservation biologists have long resisted assisted migration, mainly because introducedspecies could become invasive pests, carry diseases or upend existing ecosystems.But attitudes towards assisted migration are slowly shifting as conservationists realize justhow fast the climate is changing. Several projects are in the works now.

语篇解码

语言学习

Ⅰ. 语料荟萃

Ⅱ. 语句分析

1. There are fewer than 70 adult western swamp tortoises living in the wild in twosmall wetland reserves north of Australia. 在澳大利亚北部的两个小型湿地保护区内,生活着不到70只成年西部沼泽龟。

【点石成金】本句使用了“There be”句型,句中的 living in the wild in two small wetlandreserves north of Australia是現在分词作后置定语。

2. It's a high?risk strategy—and one that researchers have long debated. 这是一个高风险的策略,也是研究人员长期争论的一个策略。

【点石成金】本句是一个简单句,句中的that引导定语从句。

语言运用

Ⅰ. 例句仿写

1. 目的是看看这些动物能否从危险中生存下来,以及如何拯救它们。

The aim is to see_________the dangers, and_________.

2. 有一个商业概念叫作机会成本,它与金钱并没有密切的联系。

There's a business concept called opportunity cost,_________money.

Ⅱ. 写作实践

假定你是李华,你所在的学校计划举办主题为“保护动物”的海报设计比赛。请你用英语设计一张保护扬子鳄 (Yangtze alligator) 的海报。有关扬子鳄的资料如下:

注意:

1.词数80左右;

2.可以适当增加细节,以使行文连贯。
