Grandad: I want to buy a 1smartphone.
Rebecca: Do you know anything about them, Grandad?
Grandad: Yes, I do. I know they have 2touch screens, not buttons, and that you can download 3apps.
Rebecca: Yes, that's right. You can also choose different 4ringtones for different people.
Grandad: Can I get those from the Internet?
Rebecca: Yes. Now look at my phone. It has a very good 5battery. It lasts for ten hours.
Grandad: That's good. Do I need to buy a 6charger too?
Rebecca: No. It comes with the phone.
