Jack is my friend. He likes playing computer games very much. He often sits in the same way for too long 【小题1】 moving. Now he has a 【小题2】， sore eyes and a sore back. He doesn't sleep well at night, so he feels tired every day in class. Sometimes he even sleeps in class.

I think he should take 【小题3】 away from the computer. He 【小题4】 use the computer for a long time. He should do eye exercises to relax his eyes and go to bed early at night.

I think if he has a good rest, he will feel 【小题5】 soon.
