　　“What’s the matter with you？” asks mom.
　　“Ah ... I think I’ve got a toothache，” says Jason painfully（痛苦地）.
　　So， mom takes Jason to see the dentist.
　　“Nice to meet you！I’m Dr. Black，” says the dentist.
　　“Open your mouth please，” says the dentist.
　　“I am scared，” says Jason.
　　“Relax. Let’s see what’s wrong，” says the dentist.
　　“Is this the one？ Does it hurt？” asks the dentist.
　　“Yes. Ouch， that’s it，” Jason is painful.
　　Jason’s teeth are bad.
　　He has tooth decay（蛀牙）.
　　“Do you often eat a lot of
　　sweets？” asks the dentist.
　　“Yes， I can’t control（控制）myself，” says Jason.
　　“Do you brush your teeth every day？” asks the dentist.
