       Summer holiday is coming. Some kids have already made great plans for the summer.

       Travel for fun

       Many teens say they will travel with their parents during the holidays. Fan Zhe from Yantai will go to

Shanghai with his parents. "I will need a break, as I will be really tired of tests by that time," said Fan.

Gao Yuan will spend his holiday far away from his parents. From August 10, the 15-year-old boy and

20 other students at Shanghai Weiyu Junior Middle School will spend 18 days in Australia.

       Summer studies

       Some teens are spending the summer studying. Xing Wei from Tianjin and Zhou Xiaolin from Beijing

have to go to math, physics and English classes. Their parents think this will help their future studies. But

Xiaolin is unhappy, "I will spend my holiday playing with numbers. How boring!"

       Plenty of activities

        Li Yuanchen from Hefei will be doing all the usual things. "I'll be travelling a little bit, partying with

friends and reading books," he said. Shanghai's Ma Jiameng said she will spend a lot of time with friends,

doing different things. "We will do some drawing and go swimming. I will also write short stories," Jiameng said.

       Summer is a great chance to do many things. Keeping fit is an easy and cheap way to have fun.

Running, swimming and dancing are all great exercises. There is always volunteer work to do, too. Do

something! Anything! If you don't, you'll be sorry when September comes.
