Answer 1

1 C.to change
这是 带疑问词的不定式短语作宾语 相当于 一个宾语从句 =how __we can change_ the temperature ...
选项 A.can we change语序不对 应该 用陈述句 语序 故错
2 B.How does it work 这是 特殊疑问句 所以用疑问句的语序
3 这是 主语从句 .表语 是 essential 等时 主语从句的谓语 用虚拟语气 即should 加动词原形
should 可以 省略
所以 答案是 A.drink
4 这是宾语从句 当 主句谓语 含 要求 命令 主张 的意思时
宾从的谓语 用虚拟语气 即should 加动词原形should 可以 省略
所以答案是 show
