1. 由句中“mother animals”和指代空格的“them”可知，此处需填名词，baby的复数形式为babies，符合“动物妈妈保护幼崽”的语境；
2. 主语“children”为复数，固定短语“be curious about”表示“对……好奇”，结合一般现在时，故填are curious about；
3. will后接动词原形，“go wild”表示“狂热、兴奋”，符合人群看到海豚的反应；
4. 主语“animals”为复数，“give birth to”表示“生育”，符合动物春天生宝宝的语境；
5. 空格修饰名词“tradition”，需用形容词，long-standing（长期存在的）符合搭配；
6. 空格引导宾语从句，表“是否”，故用if。

五、阅读理解
Scientists today are making greater effort to study ocean currents. Most do it using satellites and other high-technology equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way—by studying movements of floating waste. As a scientist with many years of experience, he started this type of research in the early 1990s when he heard about thousands of sports shoes washing up on the shores of the northwest coast of the United States.
Ebbesmeyer found out in his researches that the shoes—about 60,000 in total—fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn't. Ebbesmeyer realised this could be a great experiment. If he learned when and where the shoes went into the water and followed until discovering where they landed, he could learn a lot about the ocean currents.
The Pacific Northwest is one of the world's best areas for beachcombing because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected useful information on 1,600 shoes. With this data, he and a workmate were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.
As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an organisation of beachcombers and ocean experts, with 500 customers from West Africa to New Zealand. They have recorded all lost objects from potatoes to golf gloves.

C. Questioning about any doubtful objects on the sea.
D. Managing a world-famous currents research organisation.
()3. What is Paragraph 3 mainly about?
A. Where about 60,000 shoes landed.
B. Whom Ebbesmeyer asked for help.
C. How Ebbesmeyer carried out his research.
D. Why the Pacific Northwest is one of the world's best areas for beachcombing.
()4. What is the author's purpose of writing this passage?
A. To call people's attention to ocean pollution.

【分析】
做这类阅读理解题时，需先明确题干关键词，带着关键词回原文定位对应内容，再将原文信息与选项对比，选出匹配项。比如第1题抓“when start research”，第2题抓“famous for”，第3题抓“Paragraph 3 mainly about”，第4题抓“author's purpose”，通过定位原文对应信息解题。
【解析】
1. 根据文章第一段“he started this type of research in the early 1990s”，可知Ebbesmeyer在20世纪90年代初开始这类研究，对应选项B。
2. 根据文章第四段第一句“Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean”，可知他因对海洋中漂浮的不寻常物体提出疑问而闻名，对应选项C。
3. 第三段主要讲述Ebbesmeyer如何开展研究：他找到海滩拾荒者帮忙收集鞋子登陆的信息，用收集的数据测试改进洋流模型，属于研究的实施过程，对应选项C。
4. 全文围绕科学家Curtis Ebbesmeyer用研究漂浮垃圾的特殊方式来研究洋流展开，因此作者的写作目的是解释这种特殊的洋流研究方法，对应选项C。
