Hà Hải Anh 123 Le Loi Street Hanoi March 2, 2026 Lao Cai City SGV Vocational School 100 New Street Binh An City Dear Sir or Madam, I am writing to enquire about the Tour Guide Training Courses advertised recently. First, I would like to know the total duration of the course and the start dates for the next intake. In addition, I wonder if the "low cost" mentioned refers to the tuition fees or if there are any scholarship opportunities available for students. Furthermore, could you please provide more details about the apprenticeship component, specifically what kind of placements are offered and how long they last? It would be great if you could also send me a detailed curriculum. I look forward to hearing from you and receiving your reply soon. Yours faithfully, Việt Dương

In today’s digital world, setting boundaries for teenagers’ device use is crucial. I believe parents should strictly limit their teenagers’ screen time to protect their health and ensure academic success.

Firstly, strict limits ensure teens have enough time for homework and essential activities. Too much screen time steals hours that should be spent studying, exercising, or interacting with family and friends face-to-face. Secondly, excessive screen time damages both physical and mental health. Prolonged exposure can cause eye strain, disrupt crucial sleep patterns, and contribute to a sedentary lifestyle and weight gain. Establishing clear time boundaries is necessary to mitigate these risks.

While some argue that the quality of screen time (like educational apps) is more important, the reality is that most teens spend their time on passive entertainment. Therefore, setting and enforcing strict limits is the most effective way for parents to teach responsibility, promote healthier habits, and ensure their children's well-being in the modern world.
