     Raising pets is a popular online game among reenagers. " More than 20 of my classmates have

adopted (领养) pets online, while last year the number was just 10," said Wang Hui, a middle school

student from Beijing, who also raises pets online.

     If you go to some websites,  you can adopt virtual (虚拟的) pets like penguins, chickens, dogs and

elephants. You can feed, wash, talk to and play with your pet.

     Dai Yingshuang of Shanghai raises pets on Kaixin001. com. The 15-year-old said it is great fun. She

thinks that she has "also learned how to take care of others".

     If one doesn't feed and care for the pet, it becomes unhappy and unhealthy.  So raising an online pet

means spending a lot of time online.

     This makes many parents worried. They fear there will be bad influence on the children's studies.

     Dai said that she usually asks her uncle to take care of her pet, while she is at school.

     Wang Zhaotong, from Anhui, has been raising a penguin on QQ.com since last year. The 14-year-old

takes good care of the penguin.

     She said her parents knew about the penguin and think it's okay.

     If the students can keep the balance between studying and playing, it's not bad for them to "raise"

pets online.
