【分析】
本题要求将每组简单句合并为并列或主从复合句，解题思路是：先分析每组两个简单句的逻辑关系（并列、递进、因果、修饰等），再选择对应的并列连词、关联连词或定语从句引导词，将句子合理连接，注意标点和句子结构的正确性。
【解析】
(1) 两句为并列关系，用并列连词and连接，加逗号分隔两个分句，合并为并列复合句；

本题为英语从句补全题，需根据括号内要求添加指定类型的从句。解题思路如下：①明确各类从句的引导词与功能：who引导定语从句，修饰先行词（本题先行词为“new energy engineer”）；so that引导目的状语从句，表主句动作的目的；if引导条件状语从句（主句用一般将来时，从句用一般现在时表将来）；although引导让步状语从句，表转折让步。②结合语境补充符合逻辑、语法正确的内容，确保句子通顺合理。
【解析】
(1) 先行词是“a new energy engineer”，需用who引导定语从句说明工程师的职责，补充从句“who helps develop clean and renewable energy for a greener future”，符合定语从句修饰规则与语境。
(2) so that引导目的状语从句，主句为“hope I can be a good engineer”，从句需说明成为好工程师的目的，补充“so that I can help more families use green energy in their daily lives”，符合目的状语从句的逻辑要求。
(3) if引导条件状语从句，主句为一般将来时（will master），从句需用一般现在时表将来，补充条件“if I keep learning and practising hard every day”，使主句结果成立，符合条件状语从句的时态规则。
(4) although引导让步状语从句，主句为“will never give up my dream...”，从句补充让步的困难情况“although there will be many difficulties and challenges along the way”，符合让步状语从句的转折语义。
【答案】
(1) I’d like to be a new energy engineer who helps develop clean and renewable energy for a greener future.
(2) I hope I can be a good engineer so that I can help more families use green energy in their daily lives.
(3) If I keep learning and practising hard every day, I will master new energy technology.
