My parents treat me like an adult.like能否换成as? 为什么?

treat like,是把...当作像什么来对待.to deal with someone or something as if the person or thing were really someone,a type of a person,or something.
treat as,是把.（真的）当什么来对待.to deal with someone or something as something.
因为,毕竟文里,我还是不是成年人,父母只是把我当做像是成年人来对待.所以用like 更好.
