Learning a Foreign Language is Interesting Work

Hello.
I'm studying English conjuctions section part of English such as because, since etc.
I have been learning a English approximately for ten years, but I'm not good at English.
I have just know learned that the "since" and "because" is have the same meaning.

I'm very interesting interested because I know learned about a grammar point and meaning that I would ordinarily guess ordinary.
