【答案】Dear Jack，
   I feel terribly sorry when knowing from your last letter that you are addicted to tiktok and in fact，it can be commonly seen that more and more teenagers get crazy about tiktok.Watching and sharing videos online have taken up their plenty of time，which makes it hard for them to focus on study.
   As a result，action must be taken before things get worse.First of all，you'd better try and develop other hobbies.Besides，communicating with friends face to face will do the trick.Only in this way will you shift your attention and form good habits.
   I do hope my suggestions will be helpful to you.Looking forward to your good news.
Yours，
Li Hua
