Cuándo usar "dónde" y cuándo "adonde"? El Español es mi idioma nativo pero siempre he tenido dudas que ahora me gustaría solventar. Desde ya gracias.

"I think" or "I think that"? For example: - I think that being a pilot is a very stressful job. - I think I want to be a pilot.

What's the difference between "unbelievable" and "incredible"?

When to use "what about you?" and when to use "how about you?" ? When somebody says: -- Hi there, HOW are you? I say: -- Hi, i'm fine, thanks, HOW about you? Is it the same if I say: "what about you?" in that situation?

Hi there! Hi everyone, it's been a long since the last time I wrote a notebook entry, so I think it's time to tell you a bit more about how is my life going. The last time I wrote here, I was not very good, I had been robbed, but now those guys are behind bars. Now I graduated highschool, and worked all the summer in order to pay for my studies. Now I'm studying and am looking forward to working on the "Ministerio de Relaciones Exteriores" (Ministry of Foreign Relations) here in Uruguay. I have improved a lot my written English, but I still lack of ability to speak English. Sadly, my spoken English is not that good as I would like it to be. Anyway I'm trying to resolve that "problem", I'm trying to improve my spoken English, but I am needing some people to chat with and practice. So, if you want to help me and talk with me, that would be nice! =D Apart from that, some things have changed, now I'm learning Portuguese and German (and also some Italian), and probably I'll be moving to my own in a few months =D It's very late (4 AM) here, I shouldn't be awake... So, I think it's time to say goodbye. It's nice to write to you again. I'll be waiting for your comments! Thank you for your help.

When to use "there's NO...." and when to use "there's NOT"? I have seen them both written on the internet. Is there something that could guide me when to use each one of them?

"talk with sb" or "talk to sb"? Is there some difference between them?

Is there some difference between "have been to" and "have gone to"?

Cuál es la diferencia entre "help" y "help out"?
