Tom: Good afternoon, Mr. Jack! Can you give me some advice on how to improve my English skills?

Jack: Of course, Tom. But first, let me ask you a few questions. What is your current level of English?

Tom: I'm pretty good at writing and reading, but I'm not very confident in speaking.

Jack: It's a common problem. Speaking takes time and practice, but there are a few things you can do to improve. For example, you could try to speak English with your friends or family, just to get more practice.

Tom: That's a good idea. But what if I don't have anyone to practice with?

Jack: You can also try listening to English radio programs or watching English language movies. That will help you get more used to the sounds and rhythms of English.

Tom: Those are great tips. I'll definitely try them out. Thank you so much, Mr. Jack!请总结以上对话的主要内容。
