解析：
【分析】首先明确时间介词at、on、in的用法规则：①at用于具体时刻（如几点几分）；②on用于具体的某一天（如星期、节日当天）或某一天的上午/下午/晚上；③in用于季节、月份、泛指的早中晚等。再结合每个句子的时间类型判断：1题第一空是固定搭配look at，第二空spring是季节，用in；2题Sunday afternoon是具体某天的下午，用on；3题Children’s Day是具体节日当天，用on；4题six o’clock是具体时刻，用at；5题this festival是具体节日，用at。
【解析】根据时间介词的用法：at接具体时刻；on接具体某天或某天的上下午；in接季节、泛指的早中晚等，结合各句语境：1. “look at”为固定搭配，spring是季节，故依次填at、in；2. Sunday afternoon是具体某天的下午，填on；3. Children’s Day是具体节日，填on；4. six o’clock是具体时刻，填at；5. this festival是具体节日，填at。
【答案】1. at; in 2. on 3. on 4. at 5. at
【知识点】时间介词的用法、固定搭配
【点评】本题考查小学英语基础的时间介词运用，需掌握at、on、in在不同时间场景的用法区别，属于常见基础题型，难度较低。
