Dear Teachers,

I am working as a teacher and I have to conduct lectures in English medium. I am not a native English speaker. So I have some problems when I am doing lectures. I can manage pre prepared lectures, but when I am explaining some matters, it was very difficult to me, becuase my flow is not continuing. It is also hapening when I am speaking English. Please help me, Are there any materials to practice speach or delivering lectures?

Thanking you
