What is the purpose of the speaker? To tell people what they should do when they _________________ here.

Welcome here, ladies and gentlemen. (16)Now I’d like to tell you what you should do when you become ill here. If you feel sick and want to see a doctor, check with the manager of your hotel. They will call a doctor for you. (17)The doctors here are busy all the time, and it may be difficult to see the doctor immediately, especially when you are well enough to go to the doctor’s office. (18)If you have difficulty explaining what is troubling you in English, your tour guide may be able to help you. You may also go to the nearest hospital, especially when you require immediate attention. (19)If you are seriously hurt and alone, make an emergency call and the operator there will help for you. Don’t be frightened if you’re sent to the hospital. People here are often sent to hospitals, so that doctors can use the special machines for tests and treatment. Unfortunately, your medical insurance can’t pay the medical bill. (20)Take enough cash or pay with your travel insurance.
