解析
本题主要考查名词、动词形式、介词、代词、固定搭配等语法点，以及语境理解能力。解题核心在于：
- 根据上下文逻辑判断空缺处所需词性（如名词、动词、形容词等）；
- 结合固定搭配或句意选择正确形式（如动名词、不定式、比较级等）；
- 注意冠词、代词的指代关系，如第9空需用定冠词表示特指。

第5空
to cry
关键点：短语“pretend to do”固定搭配，需用不定式作目的状语。
第6空
less
关键点：句中“could not care”强调“毫不关心”，需用比较级加强语气。
第7空
if/when/once
关键点：表示鳄鱼发现人类时的动作，可用条件状语从句（if）或时间状语从句（when/once）。
第8空
him
关键点：宾语需用宾格代词，指代前文的“the man”。
第9空
the
关键点：此处特指“鳄鱼这种动物”，需用定冠词the。
第10空
