Dear Tom, 

How is it going? I am writing to tell you about the Science Day in our school. 

I hope to hear from you soon. 

Best wishes, 

Li Hua

Holidays are very popular with students. They expect to relax and do something they like. However，what do holidays really mean to them？Usually，teachers will give them some homework and parents will ask them to read books，do extra exercises or take a lot of lessons. A junior high school did a survey among their students. It shows that a lot of students end up busier during the holiday. That is not only because they have many things to do，but also because they don't plan their time well. Instead of relaxing and enjoying their break，they often stay up late to finish their homework. And they find it the most painful experience. 

The following charts show some of their findings. Chart I shows different bedtimes of students during holidays. Many junior high school students go to bed late during holidays. They may forget that enough sleep is important for their health and better performance in learning. Chart II shows that more than 80% of the students read during their holidays，and 60% take extra lessons. Reading and learning remain an important part of holiday life，while doing housework and sports are not. 

During holidays，teachers should give homework which students are able to do and interested in. On one hand，teachers need to make sure students practise the key skills and knowledge when they are out of school. While on the other hand，it's important to make sure that students have enough time for something they like or want to explore. 

Parents should help their children make good plans for their holidays. Give reasonable advice and encourage them to read widely and take part in different activities. Finding a balance between having fun and improving themselves is the key to enjoying a good holiday.
