I found two very interesting sites to practice and learn English:
The http://lang-8.com is to put texts and others people correct it. In the practice is working as I thought for this here. We can also contact people because it works as a social network.
The https://www.lingq.com gives texts with translation and audio to learn vocabulary gradually. It is better to pay for the full service, which gives you access to translation and can also download the files. I’m paying $10 a month. There is also an app for the smartphone.
I found others, but they are not relevant to put here, being as copies of these two.
