解析
【分析】首先明确动词enjoy的两个核心用法：一是其后接动词的-ing形式作宾语，构成“enjoy doing sth”结构；二是固定短语“enjoy oneself”（意为“玩得开心”），其中反身代词需与主语保持一致。解题时先回忆这两个知识点，再结合句子的主语和结构完成填空。
【解析】根据enjoy的用法规则：①句中“enjoy oneself”是固定搭配，主语为we，对应的反身代词是ourselves，故填ourselves；②句中enjoy后接动词的-ing形式作宾语，括号内动词grow的动名词形式为growing，故填growing。
【答案】-ing；【即学即用】①ourselves ②growing
【知识点】enjoy的用法；固定搭配；动名词作宾语
【点评】本题考查动词enjoy的基础用法，涵盖固定短语和动名词作宾语的规则，属于英语语法基础题，需熟练掌握相关固定搭配和动词形式变化。
