aren't是are的否定式,是be动词,接形容词副词,而don't是do的否定式,是助动词,后接动词原形,这里careful 是形容词,意为小心,所以自然填aren't.你的语法有待加强,找本语法书好好看看,加强理解,做点练习,会有提高的
careful是形容词，其谓语必须是系表动词，be是系动词。
do用于动词的否定和疑问句，是助动词，但是不能用作形容词的助动词。
careful 是形容词，谓语动词要用be动词组成 主系表 的结构。
助动词do 及其否定形式 don't 是用来搭配实意动词来使用的。
假如是用don't ,那么句子应该是 if you don't do carefully, you'll be in trouble.
亲：aren't后面接形容词careful,don't后面接动词原形。
