The Black Robin 黑知更鸟

【Unit 3 Conservation 保护 · Lesson 1】

一、课文原文及逐段翻译

【原文】 Black robins are the birds that humans saved from extinction. In 1980, there were only five black robins left in the world. They all lived on a small island off the coast of New Zealand. Only one of those birds, a female called Old Blue, was able to lay eggs. Wildlife workers began a programme for raising black robin chicks. They protected Old Blue’s eggs, helped them to hatch, and took care of the chicks. Thanks to their efforts, there are now more than 250 black robins, and the population is spreading. To help them survive, people are restoring their habitats and removing small animals that hunt them, such as mice and cats from the islands where they live.

【译文】 黑知更鸟是人类从灭绝危机中拯救出来的鸟类。1980年，世界上只剩下五只黑知更鸟。它们栖息在新西兰海岸附近的一个小岛上，其中只有一只名叫老蓝的雌鸟能够产卵。野生动物工作者开始了一项黑知更鸟繁殖计划。他们保护老蓝的蛋，帮助孵化并照顾幼鸟。由于他们的努力，现在黑知更鸟已超过250只，而且数量还在增加。为了它们的生存，人们正在恢复黑知更鸟的栖息地并移除捕杀它们的小动物，例如岛上的老鼠和猫。

五、长难句拆解

【原句】To help them survive, people are restoring their habitats and removing small animals that hunt them, such as mice and cats from the islands where they live.

【主干】people are restoring … and removing small animals.

【分层】To help them survive 目的状语（不定式）；and 连接 restoring 与 removing 并列；that hunt them 定从修饰 animals；such as … 举例；where they live 定从修饰 islands。

【翻译】为了它们的生存，人们正在恢复黑知更鸟的栖息地并移除捕杀它们的小动物，例如岛上的老鼠和猫。

【考点】不定式作目的状语；并列现在分词；双重定语从句（that hunt them / where they live）。

六、语法点清单

• 定语从句：the birds (that) humans saved；small animals that hunt them；the islands where they live。
• 不定式作目的状语：To help them survive。
• 过去分词作后置定语：called Old Blue（修饰 female）。
• 并列谓语：protected …, helped …, and took care of …（一般过去时叙事链）。

七、逻辑链

1. 结论先行（首句）：Black robins are the birds that humans saved from extinction——直接点明“人类成功挽救”的主题。

2. 濒危数据（第2–3句）：1980 年仅剩 5 只、孤悬新西兰小岛、唯 1 只雌鸟可产卵，制造“濒临灭绝”的紧迫感。

3. 干预叙事（第4–6句）：野生动物工作者启动繁育计划（护卵—孵化—育雏），用 thanks to 引出成果（>250 只、种群扩散）。

4. 持续保护（末句）：以 restore habitats + remove 天敌（鼠、猫）说明保护需长期跟进，作为上篇“采取行动”的成功案例注脚。

八、写作迁移（仿写与输出）

模板：Thanks to their efforts, …

课文句：Thanks to their efforts, there are now more than 250 black robins, and the population is spreading.

仿写：Thanks to their efforts, the river that was once dead is now teeming with fish again.（多亏他们的努力，那条曾经死寂的河如今又游满了鱼。）——可用于“成效/成果”段。
