(2) more air pollution/we build/if/cause/the new factory/it may
答案

(2) If we build the new factory, it may cause more air pollution.
(2) If we build the new factory, it may cause more air pollution.
解析
【分析】
要重新排列单词组成正确句子，需先识别连词（as、if）引导的从句结构，再确定主句的主谓成分，最后补充状语等修饰成分。第(1)题中as是原因连词，引导原因状语从句，先确定从句的主语she、谓语had to stay at home，加上时间状语all day long；主句主语为Jenny，谓语是felt down，组合成完整句子。第(2)题中if是条件连词，引导条件状语从句，从句为if we build the new factory，主句为主谓宾结构it may cause more air pollution，按条件句规则排列即可。
【解析】
(1) 步骤1：识别as引导原因状语从句，从句结构为“主语+谓语+宾语+状语”，即she had to stay at home all day long；步骤2：确定主句主语Jenny，谓语felt down，结合连词as，组成句子：Jenny felt down as she had to stay at home all day long。
(2) 步骤1：识别if引导条件状语从句，从句为if we build the new factory；步骤2：主句为主谓宾结构it may cause more air pollution，按条件句“从句+主句”的规则排列，组成句子：If we build the new factory, it may cause more air pollution。
【答案】
(1) Jenny felt down as she had to stay at home all day long.
(2) If we build the new factory, it may cause more air pollution.
