Hola, Vanessa
 
Muy buenas  preguntas.... yo estoy feliz!!

1. "...., te escribo desde Barcelona" in the beginning? Can I use "...., escribí desde Barcelona"
R/ No. Because he is writing at the moment. You can say: te escribo or te estoy escribiendo

2. "estuvimos tomando" 是過去進行式嗎?? estuvimos是過去式; 但是後面加了tomando, estamos tomando是現在進行式; 所以"estuvimos tomando" 加起來變成過去進行式?
R/ Si, muy bien!
3. "me he dado", dado 的原形動詞是什麼?
R/ DARSE = to give (in this case, because of "se" to give oneself). An informal expression meaning "I gave myself a ..."

4. "Lo malo es que me voy esta tarde"  為什麼要多加me 在voy前面呢? 如果不寫me 不是意思也是一樣的嗎?
R/ Sometimes you can use either.  In this case, "me voy" is an expression meaning "I'm leaving" so you can't use just "voy" which means "I'm going to" so you will also have to add preposition "a" and the place you are going to.
