Good health is very important for very person. Still, sometimes we get ill, we call a doctor, and he examines us and diagnoses the illness. When we have a headache, a stomach ache, a sore throat, a cold, or a pain in some parts of the body, we call a doctor. He takes our temperature and our pulse. He examines our heart, our lungs, our stomach or the part where we have pain, and tells us what the matter is with us. The doctor prescribes medicine, and gives us a prescription, which we take to the chemist's, who makes up the medicine.

If you follow the doctor's orders, you get better; if you disobey the doctor, you may get worse, and even die. We must obey the doctor, if we want to get better. If we have a temperature, we must stay in bed and take the medicine he prescribes. If we cannot get better at home we must go to hospital. If we are too ill to walk, we go to hospital in the ambulance. After our illness we can go to a sanatorium until we are strong again.

When we have toothache, we go to the dentist's. He examines our teeth, finds the tooth which hurts us, stops or extracts it.

Дядя Питера жил в деревне.Однажды Питер приехал к нему, чтобы провести с дядей несколько недель. Когда они прогуливались или ехали на машине и встречали кого - то по пути, его дядя махал им рукой. Питер удивился и сказал: "Дядя Джордж, ты всех знаешь. Где ты с ними познакомился?"  - спросил Питер. "Я не знаком со всеми этими людьми" - сказал его дядя. "Тогда почему ты им махаешь?" - спросил Питер. "Ну, Питер" - ответил дядя. "Когда я махаю кому - то и он знает меня, он счастлив. Он идёт дальше с более радостным сердцем. Но когда я махаю кому - то и он не знает меня, он удивлён и говорит себе: "Кто этот мужчина? Почему он мне помахал?" Так что у него есть что - то, о чём подумать по пути, и путь кажется короче. Так что делаю всех счастливым.
