Dear Sir or Madam,

I am writing to enquire about the tour guide training courses advertised by SGV Vocational School. I am very interested in becoming a tour guide because I enjoy travelling and learning about different cultures.

First, I would like to know more about the course content and its duration. Could you please provide information about the subjects taught and how long the training lasts? In addition, I wonder if the course includes practical field trips or only classroom lessons. I would also appreciate it if you could tell me more about the apprenticeship program, such as where it takes place and how long it is.

Finally, I would like to know the total course fee and the starting dates of the upcoming classes.

I look forward to receiving your reply.

Yours faithfully,
Minh

I strongly believe that parents should strictly limit teenagers’ screen time. Nowadays, many teenagers spend too much time on phones, computers, or watching TV, which brings many negative effects. First, spending too much time on screens leaves teenagers little time for homework or other useful activities. Many students spend hours watching online videos, checking social media, or playing computer games instead of studying. As a result, their school performance becomes worse, and they often feel stressed before exams. Second, too much screen time is bad for teenagers’ health. Staring at screens for long periods can damage their eyesight and cause headaches. It also reduces their sleep time because many teenagers stay up late using their phones. In addition, sitting too long in front of a screen can lead to weight gain and other health problems. In conclusion, limiting screen time helps teenagers focus more on their studies and maintain a healthy lifestyle. Therefore, parents should set clear rules to control how much time their children spend in front of screens.
