I completely disagree with you Igor, I was born in Brazil, where there are close to none fluent english speakers. My english however may actually be better than my portuguese. Sure, I've been learning it ever since I was a kid, but I don't have any friends that speak it, nor do I use it on a daily basis.

Even though I wasn't born in the US, I can assure you my english is better than at least half of the american population. This goes to show you that there is no such thing as "fooling oneself", you just have to change your mindset. Sure, you can start by translating vocab from your mother tongue but it can only get you so far, for there are plenty of words that have multiple meanings and can't be translated.

 Take greek for instance, there are four words all with different meanings that would be translated to "love" in english. Well... they do mean love but in 4 different ways that cannot be expressed in english using one single word.

If you want to speak like a native, think like a native.

A warning is an advice, a symbol or a written text that informs you to be aware about someone or something, e.g. "This warning states there are bears in the vicinity". Caution is something you have when you are aware of something or someone that can harm you in some way and you act in a way to prevent said harm, e.g. "There are bears in the vicinity, proceed with caution".

I understand where the other guys are coming from, these are classics, very much like Arthur Conan Doyle, Mark Twain or Robinson Crusoe. I respect that, but not everyone likes them and for someone who's learning a new language, the last thing you'll want is boredom, not to mention some of them are hard to read even for natives. You could always go for something a little more modern like "A batalha do apocalipse" or "A lenda de Ruth Ghanor".

Our community is large, with nearly two thousand households in it. In the middle of the neighbourhood, there is a central garden with a little pool. A lot of children like playing around it., and in the evening, after dinner, some retired elderly people <strike>liking</strike> like to dance <strike>dancing</strike> around it <strike>too</strike>.
There is a swimming pool near the gate of our <strike>the</strike> community which is usually open<strike>ed</strike> <strike>in</strike> from July <strike>and </strike>to August., <strike>Because</strike> <strike>at that time</strike> for schools are out for the summer, and many children like to swim in it.
<strike>Coparing</strike> Compared to other Chinese <strike>community</strike> communities, we have <strike>be more wider floor spacing</strike>.bigger houses, so it feels spacious and comfortable.

this structure is used for something that could've been done(started and ended) in the past, you're using it for something that could still be ongoing and thats wrong. the correct would be "he _____ have become prime minister, if he hadn't left politics" or you could say "he _____ be prime minister now, if he hadn't left politics" the second phrase is much closer in meaning to what you've meant to say but it doesn't support the third option, "might". Now answering your queston: 1. there is a possibility that could have happened 2. that would have happened for sure(100% chance) 3. there is a high chance that could have happened

The thing is, I don't think you want to change your opinion at all. I wrote a big comment with plenty of music and content that someone like you could appreciate yet you didn't even acknowledge it, you're too busy excusing yourself to focus on the main point of your question.

If you're still in need of help, I'd love to help out a fellow language enthusiast
