Alan: It is Saturday, Dad.

Dad: What about going to the cinema? I like watching movies.

Alan: Good idea.

Dad:

Alan: There's no bus or subway getting there.

Dad: Sorry, we can't. The traffic is so heavy, so I want to go there by shared bike(共享单车).

Alan: By shared bike? That sounds good.

Dad: No, it's not free(免费的), hut it's very cheap. It costs only one yuan per hour(每小时)..

Alan: Wow! Let's go, Dad. I can't wait!

(Dad and Alan find two shared bikes on the street.)

Alan: Dad, I have never(从未) tried it before.

Dad: Scan the QR code(扫描二维码) on the bike, and then it will unlock(解锁). Now you can ride the bike. But children under 12 can't ride the bike. It's banned(禁止的).

Alan: I see, Dad. I am 13 years old.

Dad: Yes. Off we go, Alan.

Alan: Great.

(Dad and Alan arrive at the cinema.)

Alan: Dad, here we are, in front of the cinema.

Dad: Good question(问题), Alan. We can't park(停放) the bikes randomly(随意的). We should put them in the right place.

Alan: Oh, I find the parking zone(停车区). Let's put the bikes here and lock them.

Dad: Good boy!
