Jane: Good morning, Harry! What are you reading now?
Harry: Hi, Jane. .
Jane: Ancient Rome? Sounds interesting! ?
Harry: Oh, I have read the book for a few hours. I'm a little tired and want to go for a walk.
Jane: Good idea. I saw a bracelet(手环) on your left hand. ?
Harry: It is used for getting information about how many steps I take during a day. Jane: That is such an amazing invention!
Harry: And it sends the information into my mobile phone and also I will know how many steps other friends take if they have bracelets as well.
Jane: yesterday?
Harry: Umm, it was Alex. He took more steps than others, and he is always on the top of all my friends.
Jane: Great! He really enjoys walking. Now let's walk together!
Harry: .
