You had "cuz" and "wanna" -- if you are writing in chat, this is okay, as long as you know they're slang! English speakers say both when they're speaking or typing informally.

In Arabic you don't need an article when introducing your job, but English always requires this. "I am a teacher. I am an engineer."

Usually, you don't need an article before a country name ("I want to work in Switzerland" or "I want to work in England"). But some countries do require this, especially if they begin with "United" ("I want to work in the United States," "I want to work in the United Kingdom," "I want to work in the UAE").

I went to a concert, by the Syrian singer Sameh Shoquir. It was held to support the Syrian people and to collect donations for them. Syrian youth at the break cheered and yelled. They said, "GOD curse your soul, Bashar!" I loved the day and I have fallen in love with the Syrian accent. [totally it captured,] I was happy when I heard them and remembered our cheers against authority.

totally it captured  - I'm not sure what you mean here...

cheers - I might say "fight against authority" or, if you are talking about things people say at demonstrations, "chants against authority." (الشعب يريد إسقاط النظام = a chant)
