| Mary: Welcome to the English club. Today we're going to talk about the best ways to learn English. 1. Jim: Do you learn English by watching English-language videos? Helen: No: It's too hard to understand the voices. Jim: 2. Do you learn English that way? Helen: I think so. It helps to write English everyday. Gina: 3. Helen: Yes, I have. I've learned a lot that way. Mary: Do you ever practice conversations with friends? Helen: Oh, yes. 4. Jim: What about reading aloud to practice pronunciation? Gina: 5. I think it helps. Ben: I do too. And I always look up new words in a dictionary. Gina: That's a great idea!
