解析
本题主要考查动词形式变化、介词使用、时间表达、比较级、固定句型等语法点。解题核心在于：
- 根据上下文逻辑关系判断空格处需要表达的时间顺序或比较关系；
- 结合固定搭配（如
so...that结构、see sb do sth用法）； - 注意词性转换（如动名词、比较级、物主代词等）。
第1空
比较级用法：a million times强调程度，faster表示光速远快于声速。
第2空
时间介词：in one second表示"在1秒内"，固定搭配。
第3空
动名词作主语：by watching表示"通过观看"，动名词作方式状语。
第4空
动词原形：see sb do sth表示"看到某人完成整个动作"，此处指看到发令枪冒烟的全过程。
第5空
时间顺序：before表示"看到烟比听到声音早"。
第6空
固定句型：so far away that构成so...that结构，表示"如此远以至于"。
第7空
时间状语：four years ago表示光从四年前开始旅行。
第8空
物主代词：journey是名词，需用its作定语。
第9空
否定表达：cannot表示"不能说"，强调客观限制。
第10空
现在完成时：shining表示光从过去持续到现在的状态。
