haha. yup. まだ=not yet; でも=but. おなかが本当にすきました means i am really hungry. すきました can be replaced with すいた though.

and もう=already; 昼ごはん=lunch. as for the last sentence: 'あとでね、昼ごはんをぜったいたべる', it means that i will eat my lunch later... ^^ but then i am god damn sure my sentence structure is very very wrong! haha!
i skipped elementary 3 and going on to intermediate next year, but i keep on thinking of re-learning elementary 3... cuz i am feeling quite insecure with not learning E3 and jumping over to the next level... scared i cannot cope... especially the kanji. should i? =/
btw, can somebody please refresh my memory on what are the meanings of 'もう'? i only remember it being 'already', but i just cant seem to remember whats the other meaning of it! おしえてください。どうも。
oh wait! another question! hehe. (x what's the difference between doumo and arigatou? when do we use the appropriate ones? thanks in advance! ^^
