七、信息还原。
阅读短文，从短文后所给的 A-G 七个选项中选出五个能填入空白处的最佳选项。选项中有两项为多余选项。
The Chinese crested tern is a type of seabird. The bird is about 30-40 cm long, with a black crown, gray wings and a white body. They live mainly on small fish. 1 According to a report, there are only about 150 Chinese crested terns all over the world.
The first record of the bird was in Indonesia in 1861. 2 Scientists once believed that this type of bird may die out. Amazingly, over 60 years later, some birdwatchers saw many Chinese crested terns in Fujian and Zhejiang.
Scientists working in a nature reserve in Zhejiang wanted those birds to stay there. They built some artificial nests(人工鸟巢). They even put some handmade birds of the same size as Chinese crested terns there. 3 More and more Chinese crested terns flew to the islands and laid their eggs.
Chinese crested terns lay eggs as the weather gets warmer, usually between April and August. 4 During their stay in Zhejiang, scientists and volunteers from a Chinese crested tern protection project do a lot of work. They record the information of every bird on the islands. They help them lay eggs safely. 5
Not only the government but also bird lovers are taking action to protect the valuable birds. You're welcome to join them. Hope there will be more and more Chinese crested terns flying in the sky.
A. Everything went well.
B. Bird lovers come here.
C. It lives in a very special way.
D. The number of the birds is very small.
E. However, after the 1940s, people couldn't find them.
F. When it gets cold, they fly to southern areas to spend the winter.
G. Also, they drive away some dangerous animals like snakes and mice.

【分析】
做这类信息还原题，首先要通读全文，明确本文是介绍珍稀鸟类中华凤头燕鸥的科普文章，再逐空分析前后文的语义逻辑，匹配对应选项：
1. 第1空后文直接给出“全球仅约150只中华凤头燕鸥”的描述，前文必然是引出该物种数量稀少的特点，对应匹配选项。
2. 第2空前文提到1861年首次记录到该鸟类，后文提到科学家曾认为该物种可能灭绝，中间需要补充“有段时间人类找不到该鸟类”的过渡内容，匹配对应选项。
3. 第3空前文描述科学家为留住燕鸥做了搭建人工鸟巢、放置仿真鸟的诸多努力，后文提到越来越多燕鸥飞来产卵，说明措施取得了好效果，对应衔接“进展顺利”的选项。
4. 第4空前文提到燕鸥在天气转暖的4-8月产卵，后文提到它们在浙江停留期间工作人员开展保护工作，需要补充冷季燕鸥的迁徙行为，和前文暖季的行为形成对应，匹配对应选项。
5. 第5空前文已经列举了保护人员的两项工作，需要补充说明其他的保护工作内容，匹配对应选项。最后排除和全文语境无关的两个多余选项即可。
【解析】
1. 空后句“According to a report, there are only about 150 Chinese crested terns all over the world.”直接点明该鸟类总数量极少，和D选项“The number of the birds is very small.”形成完美语义承接，因此选D。
2. 空前句说明1861年就有该鸟类的首次记录，空后句说明科学家曾判定该鸟类可能灭绝，E选项“However, after the 1940s, people couldn't find them.”补充了中间人类长期找不到该鸟类的时间节点，承上启下符合时间逻辑，因此选E。
3. 空前描述科学家为留住燕鸥采取了一系列干预措施，空后说明燕鸥主动飞来产卵的好结果，A选项“Everything went well.”直接说明所有措施都取得了预期效果，衔接前后内容，因此选A。
4. 空前提到燕鸥在天气变暖的4-8月产卵，F选项“When it gets cold, they fly to southern areas to spend the winter.”和前文暖季的行为对应，符合候鸟的迁徙习性，逻辑连贯，因此选F。
5. 空前列举了保护人员记录鸟类信息、协助燕鸥安全产卵的两项工作，G选项“Also, they drive away some dangerous animals like snakes and mice.”是对保护工作内容的合理补充，语义连贯，因此选G。
【答案】
1. D 2. E 3. A 4. F 5. G
【知识点】
语篇逻辑推理，阅读信息还原
【点评】
本题是典型的初中英语七选五信息还原题型，围绕珍稀鸟类中华凤头燕鸥的科普内容展开，解题核心是抓住前后句的语义关联、时间线逻辑和并列补充关系，不需要复杂的语法知识，重点考察学生对语篇整体脉络的理解能力，两个多余干扰项和全文语境没有匹配点，区分度较高。
