问题描述：
have you made up your mind how to cheer up the sick kids?by singing songs 句子的结构能讲一下吗?谢
答
have 放在句首,做一般疑问句提问
you 主语
made up 谓语.时态是现在完成时.
your mind 宾语.
到这里,句子的主要成分就全了.改成陈述语气就是：You have made up your mind.
how to cheer up the sick kids 是由 how to 引导的方式状语从句.sick kids 是 cheer up 的宾语.
By singing songs.是省略句.
完整的句子是：I cheer up the sick kids by singsing songs.
所以答语的主语是 I（也就是问句里的那个 you）
by singing songs 是宾语补足语,是用来修饰 sick kids 的
