Dear Sir or Madam,

I am writing to ask for more information about the tour guide training course at SGV Vocational School. First, I would like to know how long the course lasts. I also want to know how many days a week we study. In addition, could you tell me if we have practical training or an apprenticeship? I would also like to know the total cost of the course. Are there any extra fees? Furthermore, when does the course start and how can I apply? I am very interested in becoming a tour guide because I like traveling and learning about different cultures. I hope you can give me more details about the course. I look forward to hearing from you soon. Yours faithfully,

Tran Tu Uyen

Nowadays, many teenagers spend too much time on their phones, computers, or watching TV. I think their screen time should be limited for several reasons. First, using screens for too long is bad for their health. It can hurt their eyes and make them sleep less. Second, too much screen time can make teenagers lazy and less active. They may spend less time studying or talking with family. If their screen time limited, they will have more time for exercise, reading, and real-life communication. In conclusion, limiting screen time helps teenagers stay healthy, learn better, and live a more balanced life.
