Sorry to disappoint you. I don't have book shelf at hom at all. No such habit of keeping books. Fortunately, I have libraries. Simply following the old Chinese saying : One truly reads books which are borrowed (instead of bought). Still a long and difficult way to go in terms of improving English.You guys are young and excellent at spoken English, which I admire the most.
Seems like NewVoice is very good at English. I admire NewVoice has a teaching position.
