【分析】
本题考查时间状语从句的连词及固定搭配的运用，解题时需结合上下文逻辑关系和常用短语来选择合适的连词。第1空，前半句“过去觉得做饭容易”与后半句“开始学做饭”存在先后顺序，需选表“在……之前”的连词；第2空，后半句“发现做饭不简单”是在“第一次尝试做蛋炒饭”这个时间点发生的，需选表“当……时候”的连词；第3空，结合语境和固定搭配，需选表“直到……才”的连词。
【解析】
1. 由语境可知，“认为做饭容易”发生在“开始学做饭”之前，故填before；
2. 此处表示“当第一次尝试做蛋炒饭时”，用when引导时间状语从句，故填when；
3. 固定搭配not...until意为“直到……才”，符合“没有停止尝试直到成功”的句意，故填until。
【答案】1. before 2. when 3. until
