Script:

Mai: Mike, our teacher mentioned that university students are expected to be independent learners. How do you think we can become independent learners?

Mike: That's an interesting question. Look, this website has information about it. It says independent learners have four main characteristics.

Mai: So what are they?

Mike: Firstly, they're self-motivated. They enjoy learning new things. No one has to force them to study. They never wait for their parents or teachers to help them or tell them what to do.

Mai: I agree. It's the motivation for learning that makes people study hard.

Mike: Secondly, independent learners are responsible. They take responsibility for their own learning

Mai: Are there any examples?

Mike: Yes, they set their own learning goals and make detailed study plans to achieve them. These study plans should also include time to relax and enjoy a good night's sleep.

Mai: I see.

Mike: Thirdly, they never give up. Once they start working on a task, they try very hard to complete it.

Mai: I definitely agree.

Mike: Finally, they're curious. They want to know more about the world. They're not afraid of asking difficult questions, but they also try to find the answers themselves.

Mai: I couldn't agree more. I hope I can try to become an independent learner.
