First of all, you think it's a waste of time to watch some boring TV programmes. Why
not ask your parents to recommend a list of good programmes, so that you can make a good
choice?
What's more, some students keep talking about TV programmes at school. It may drive
you mad and have a bad influence on study. You should remind them to pay attention to
schoolwork and keep a balance between school and TV programmes.
At last, some students stay up late to watch TV. Getting enough sleep is of great importance
to teenagers. It is a good idea to manage time well and go to bed earlier.
I hope my suggestions can be of help to you.
