My first English class.

I have just had my first English class.
My teacher is very good. During the class, I could only speak in English and so my teacher could.
I think that I'm going to improve my English with this teacher.
Today, I did some listening exercises. It took me awhile, but I was ready to improve.

I hope I can learn English in a few months.
