【分析】
这是一篇基础的短文语法填空题，解题时首先要通读全文，确定文章整体时态为一般现在时，明确主题是介绍大堡礁的现状与保护措施。接下来逐个推导空格：首先结合句子结构、固定搭配判断空格所需的词性，再结合时态、句法规则、逻辑关系对给出的词进行变形，没有提示词的空格要结合固定搭配和前后句逻辑判断填写的虚词，最后通读全文验证所有空格语句通顺、逻辑合理即可。
【解析】
1. 本句是地点状语前置的倒装结构，主语是后面的单数名词a wonderful natural wonder，全文为一般现在时，谓语动词要用第三人称单数形式，lie的三单形式是lies。
2. 句中给出范围限定in the world，表达“世界上最大的珊瑚礁”，定冠词the后要使用形容词最高级，large的最高级为largest。
3. 考查固定搭配be full of，意为“充满”，因此填介词of。
4. 此处表达“第一个问题是气候变化”，定冠词the后要用序数词表顺序，one对应的序数词是first。
5. 后半句“海洋生物需要珊瑚作为食物和栖息地”是前半句“珊瑚对海洋生物很重要”的原因，表因果逻辑的连词填because。
6. 考查固定句型It's + 形容词 + for sb./sth. to do sth.，意为“对……来说做某事是……的”，因此此处填不定式to live。
7. 句中系动词是are，说明主语为复数，scientist的复数形式是Scientists，位于句首首字母需要大写。
8. 考查固定结构keep sth. + 形容词，意为“使某物保持某种状态”，health的形容词形式是healthy。
9. 空格后有名词things，需要用形容词性物主代词修饰名词，you对应的形容词性物主代词是your。
10. 空格处修饰动词shining，需要用副词形式，bright的副词是brightly。
【答案】
1. lies 2. largest 3. of 4. first 5. because 6. to live 7. Scientists 8. healthy 9. your 10. brightly
【知识点】
动词时态，词性转换，固定搭配
【点评】
本题属于初中阶段基础难度的语法填空，主题贴合海洋环保的常见话题，绝大多数考点都是课内核心的固定句型和词形变换规则，仅连词类空格需要学生梳理前后句的逻辑关系，整体能有效考察学生对基础语法的掌握程度。

We share the Earth with millions of animals. How much do you know about them? Here are some important facts.

2. Let's take ants as an example. An ant family usually has millions of ants. Some ants are strong enough to fight with dangerous animals and protect their home. Some take care of babies. Others go looking for food.
