Where can you find input?
Input is "food" for your brain. You can feed your brain with anything that you listen to or read. For example:
The hard part is to find something at your level. The way to improve your English the fastest is to find something that is not too hard for you. You should be able to understand most of it, so that you can use what you know to understand the new words and phrases.
That's what this website is for. In fact, it's called ESLbookworm because most of this site is made up of stories. Stories are an excellent way for you to learn vocabulary, natural expressions, and general comprehension. During my years of teaching English abroad (to many different levels of students), I wanted stories that were just right for my students. That's why I started writing my own stories that built from easy to hard. My students have found them fun and useful, and I hope you will too.
