What did  has italki give me?

As I told mentioned maybe in my first or second publication, I don't remember, but the Italki allows me to meet a lot of awesome people. I am so glad to meet new friends from differents countries such as Spain, Turkey, France, China, Morroco, and etc. I want to travel around in the world one day, so, I want to meet more and more people from every country that I wish to go. Some friends that I've met are not fluent but we get to talki,. I like to send audio and receive it too (or you can say "I like to send and receive audio clips with them). My biggest problem is listening. I have difficulty comprehending audio still. Sometimes I can listen or not, depending on the situation, because I have friends who speak fast and others that speak slower. When I started to talk in audio clips with some friends, I managed to improve a little but I need more and more practice. I try practicing with movies and songs. Actually, when I talked with some foreigners I didn't feel it was difficult, maybe because they speak slower. I understand them, but with movies I feel it's more difficult to listen to than my language partners, and with simultaneous translation *Perhaps you could say, and with movies I need to simultaneously translate them. I would like to learn to listen American and British accent (others too). And when I start my vacation I will start to read Harry Potter in English. I have never read Harry Potter, even in Portuguese, so it will be a challenge for me. I hope I can learn more...

What did italki give me?

As I've previously said (or previously mentioned), Italki allows me to meet a lot of awesome people, and I'm so glad  (or happy, thrilled, excited, etc.) that I'm making new friends in different countries like Spain, Turkey, France, China, Morroco, etc. (Leave out the 'and' in 'and etc.'). I want to travel around in the world someday, and I want to meet (or 'I hope that I meet') a lot of people from each (or 'every'. Either one works.) country that I want to go to. Some friends ('people' might be better than 'friends' in this case) that I met are not fluent but when we get on italki, we like to send each other audio messages. (You could also say 'we like to talk to each other'.) My biggest problem is being able to know what people are saying (when they're talking). It's still a little difficult (or 'hard') to understand what they're saying. (You don't really need that last sentence, because you're really just repeating what you already stated.) It really just depends on how fast they talk; it's usually easier to understand them when they talk slowly.  When I first started italki (leave out the 'to'), my friends and I would always voice chat (each other), and I managed to improve a little, but I still have a lot to learn. I try learning by watching movies and listening to songs. Actually, when I talked with some foreigners, it wasn't all that bad, probably because they spoke slower so I could understand them, but with movies I find it a (little) bit more difficult to know what's going on. I would like to learn how to speak (in) an American (accent) and a British accent (and others, too). And when my vacation begins (or 'starts'), I want to (or 'would like to') read Harry Potter in English. I've never read Harry Potter before, not even in Portuguese, so it will be a challenge to me. I hope I can learn more...

Overall, your English is very good, there's just a few things here and there that can be tweaked, but I'm impressed at your progress! By the way, in most conversations, 'I am', 'You are', 'He is', 'They will', etc. will be shortened with a contraction (and will be pronounced like): 'I'm', 'You're', 'He's', 'They'll', basically any time you have a pronoun and a conjugation of the verb 'to be' (am, is, are) or the auxiliary word 'will' (sorry if that was confusing :/. Here's an example: "I am going to the store" is usually "I'm going to the store" and "She has been studying calculus for three years" would be "She's been studying calculus for three years." Like I said, you almost always would use this contracted form when talking with someone, or when casually writing to or texting a friend, or other familiar person. However, in formal papers like essays, for example, most teachers/professors make you write it without contractions, as that way is more 'formal'.) If you ever have questions about grammar, or anything about English, just ask, and we'd be very willing to help! Good luck! (Have fun reading Harry Potter, I've never read  it!)
