Good morning, Tom. Why do you look sad?<br />Mum, my bike doesn't work. Could you please drive me to school now? I'm afraid that I'll<br />be late for school today.<br />Don't worry, it's just 7 am now. You have time. The school begins at 8 am.<br />Yes, you are right.<br />I think you can even walk there. It often takes you 20 minutes to walk to school.<br />That sounds like a good idea.<br />Good morning, Tom. Why do you look sad?<br />Mum, my bike doesn't work.
