本题为英语句子改写题，需根据不同要求转换句子结构：
(1) 要求保持句意不变，原句是when引导的宾语从句，从句主语与主句间接宾语对应的主语一致，可转换为“疑问词+不定式”结构简化表达；
(2) 要求改为被动语态，需将主动句的宾语变为被动句主语，结合原句时态（一般将来时）转换被动结构，同时引出动作执行者；
(3) 要求对划线部分提问，划线部分为方式状语，需用对应的特殊疑问词提问，并调整语序构成特殊疑问句。
【解析】
(1) 原句宾语从句为“when I could have breakfast”，主语与主句宾语对应的主语一致，转换为“when+不定式”结构，故填when to；
(2) 原句为一般将来时主动句，被动语态结构为“will be+过去分词”，主动句宾语our plan作被动主语，动作执行者the school由by引出，故填will be used by the school；
(3) 划线部分是表示方式的状语，用How提问，将情态动词can提前至主语buildings前，其余部分语序不变，故为How can buildings save more energy?
【答案】
(1) when to (2) will be used by the school (3) How can buildings save more energy?
【知识点】

这类连词成句题需先分析所给单词的词性与含义，再结合英语基本句型（如结果状语从句、让步状语从句）确定句子结构，最后按逻辑排列成分。第(1)题需用到so...that结构，先确定主句的主语、修饰语与表语，再安排that引导的结果从句；第(2)题是although引导的让步状语从句，需注意从句与主句均用陈述语序，且although置于句首。
【解析】
(1) 步骤1：识别核心结构so...that（如此……以至于）；步骤2：确定主句主语为the performance，地点状语at the festival修饰主语，表语为so wonderful，构成主句The performance at the festival was so wonderful；步骤3：that后接结果状语从句，主语everyone，谓语cheered loudly，组合成完整句子。
(2) 步骤1：识别让步状语从句引导词although，置于句首；步骤2：从句主语为the Eiffel Tower，被动结构was once criticised by artists构成从句；步骤3：主句主语it指代the Eiffel Tower，表语为now the symbol of Paris，构成主句，组合成完整句子。
【答案】
(1) The performance at the festival was so wonderful that everyone cheered loudly.
(2) Although the Eiffel Tower was once criticised by artists, it is now the symbol of Paris.
