- A partner (someone's like your international/native friend) - Travelling - Work in a foreign company

Their grammars are not the same. So you must: 1 - Learn phrases (this is most important) 2 - Learn and understand the grammar (join an English class) 3 - Learn the way of speaking everyday (watching movies, news, sports: Disney Channel, Star movies, BBC...) 4 - Talk more (find a partner, a chance of speaking) I'm sure when you will have a "sense", "feeling", you will be surprised when you can say a lot of things (although not always) without thinking much. Don't worry, some native speakers are not good at speaking, they can't even describe their ideas, and a good speaker makes mistakes sometimes :)

You can use "a" in general case, like for the first time of talking about it. Then you can use "the" later.

Don't worry about this. You can say "I've bought a new game" in general, notice: in general About "a" or "the", you can find it easily on many pages, books. My simple idea: - When you talk about something the first time, you use "a" e.g. I have bought a new car today! - The next time of mentioning, you can use "the", or some similar words such as "that,..." e.g. The car is so shiny! ^^ or. That car is so shiny (suppose it's not here at the time of speaking)

... and Google also gave up this market :(
