健兒乙：Sorry, I don’t understand Chinese…. What you are talking about?
健兒甲：哦! 講英文,香港係一個國際大都會! 等我盡地主之誼, 招呼你!
健兒乙：I am a Korean…. It’s my first time I ran marathon in Hong Kong.
健兒甲：It’s very nice to meet you. You look very healthy!
健兒乙：Thank you! Well, I have a little secret …
健兒乙：If you want to be healthy, you can drank some tea every morning.
健兒乙：You may went for a quiet and leisurely walk, before or after a shower.
健兒甲： I don’t understand…
健兒乙：You don’t understand .Why?! This may because a walk calms you down. Oh! You must slept 7 or 8 hours a day if you want good health.
陳：這位韓國朋友十分有智慧，他對健康的確有研究。但我可以改正他的錯誤Modal verbs用法! Modal verbs即是情態詞，例如 can, may, must, shall, will之類。它們的用法就是要配一個bare infinitive，即是一些原形的動詞。好像剛剛他所說的配搭其實應該改為, can drink, may go, may be because, must sleep
健兒甲：Hey! You mean if I want to be healthy, I can drink some tea every morning. I may go for a quiet and leisurely walk, before or after a shower. This may be because a walk calms a person down and I must sleep 7 or 8 hours a day.
健兒甲：Hey, thanks for your tips.
