Tomoko - Congratulations on your choice to study English. I wish I had the nerve to study a foreign language. I lived in Corpus Christi for 7 years, and became quite proficient with Tex-Mex, but I've been gone so long, I've ;forgotten it all. Maybe if you practiced it on a tape recorder, you could hear yourself when you play it back. Just a thought. Best wishes, Jo Ann from Houston
