Hello,
Is there an English speaking show on TV in your area?
Before I came to the US, I learned French as a second language for many years and English as third language for one year. I could only write and read in French. I was very weak in English. Now nearly three decades later living in the US, I looked back and credited my English speaking skill from watching lot of TV shows like "Three's Company". Also I was forced to speak English daily with other people. Learning a new language is like learning a new skill. Practice makes perfect. By the way my French language is now gone. Best of luck to you and your students.
Sincerely.
