catch me ,if i fall.alway believe you帮我解释清楚

同学,你的分析也太乱了.
你可以这样看,
you are not going to catch me,stuck in the house without a thing to eat.
catch只是一个动词 后面跟着宾语me.
后面是一个句子 stuck in the house without a thing to eat.
这个句子是省略了主语和宾语的,从句的连接词也省略了.
这个句子直接翻译就是
你不会捉到我呆在家但是没有吃东西的场面.
意译就是
你想捉到我呆在家而不吃任何东西的场面是不可能的.
也请你看看stuck的意思
stuck in
a.忙碌的(专心致志的)

有两个意思
一个意思是抓住我
不如说you can't catch me.你抓不到我.
一个意思是赶得上

这句话没有错误 ,语法正确.意思为没人能跟上我 或者 没人能理解我的话.

catch me if you wanna
假如你喜欢就来追我
