【分析】
首字母填空的解题思路：先通读句子理解整体句意，再结合首字母提示，分析句子所需单词的词性（名词、动词、形容词等），同时考虑时态、主谓一致、固定搭配等语法规则，最后验证填入的单词是否符合语境和语法要求。
【解析】
1. 句意：今天早上我睡过头了，因为我的闹钟没响。闹钟没响导致“睡过头”，对应单词oversleep，此处用过去式overslept。
2. 句意：幸运的是，被困在燃烧的建筑里的人被救出来了。修饰building需用形容词，burn（燃烧）的形容词形式burning（燃烧的）符合语境。
3. 句意：他在交通事故中没有死亡，现在仍然活着。此处需形容词作表语，alive（活着的）符合句意。
4. 句意：王先生宣布我们明天将去野餐。主语Mr Wang是第三人称单数，句子为一般现在时，动词用第三人称单数形式announces（宣布）。
5. 句意：我真傻，居然相信他是个好人！此处需名词，fool（傻瓜）符合语境。
6. 句意：由于污染，那个山村的美景可能会永远消失。disappear（消失）符合“美景因污染不见”的逻辑，且与will搭配用原形。
7. 句意：她关于野生动物的发现会改变人们对它们行为的传统观念。her后需名词，discovery（发现）符合句意。
8. 句意：铃响后，所有学生冲出了教室。句子为一般过去时，ring（铃响）的过去式rang符合时态。
9. 句意：医生们一直抢救那位老人直到他醒来。till（直到）引导时间状语从句，符合句意。
10. 句意：她的教学经验让她比其他求职者更有优势。advantage（优势），固定搭配give sb an advantage over sb（比某人有优势）。
11. 句意：他们去年杀了很多鲨鱼，他们多残忍啊！cruel（残忍的）符合语境。
12. 句意：当一个国家的工业发达时，那里的人们会富裕并过上更好的生活。industry（工业）符合句意。
13. 句意：这是一个科学实验。修饰experiment需形容词，scientific（科学的）符合。
14. 句意：我不喜欢狮子，因为它们很丑。ugly（丑陋的）符合语境。
15. 句意：人们把垃圾扔进河里，让河水变得很脏。litter（垃圾）符合句意。
16. 句意：我们应该回收废纸来保护环境。recycle（回收）符合“回收废纸”的逻辑，should后用原形。

【分析】本题为英语单词适当形式填空题，需结合句子结构、语法规则（如词性修饰、时态语态、名词所有格、比较级最高级、非谓语动词等），对括号内单词进行合理变形，具体需判断每空所需词性、语法结构后再变形。
【解析】1. 空处修饰形容词possible，需用副词，true的副词形式为truly；2. 此处表示“英雄的名字”，one of后接名词复数，以s结尾的复数名词所有格直接加’，故为heroes’；3. 由I have ever met可知是三者及以上比较，需用形容词最高级，strict的最高级前加the，故为the strictest；4. since引导的时间状语从句，强调动作对现在的影响，用现在完成时，主语为you，故为have graduated；5. until引导的时间状语从句用一般现在时表将来，work与finish是被动关系，故为is finished；6. than是比较级标志，slim的比较级需双写m加er，故为slimmer；7. 空处修饰整个句子，需用副词，hope的副词形式为Hopefully；8. 此处表示“游客的身份证”，all后接名词复数，其所有格为visitors’；9. 空处修饰动词walk，需用副词，comfort的副词形式为comfortably；10. 此处为感叹句，how后接副词修饰动作，sad的副词形式为sadly；11. 此处表目的，用不定式作目的状语，故为to treat；12. when引导的省略句，完整结构为when (they are) brushing teeth，故用现在分词brushing。
