Special Forces

Last december I had one interesting grammar course with the funny name 'Language Special Forces' (I'm not sure but it's like military English)) Next part of this cours started this week, and it is about vocabulary, lexis. And I really see that I have a problem with it! I need to learn a lot of new words and use them, but I try to use imnly simple sentences and words. I hope this course will help me with it. By the way, right now I have to do my homework)))
