 grow up carrying a book wherever you go, just as she does.But parents do a lot more than just

 pass on their hobbies. Moms and Dads need to care for their kids the minute their kids are born.

 Most parents will do this as long as they live.

      Here are some ways you can stay close, get along well, and build a strong relationship ( 关系)

 with your parents.

      Spend time together. Instead of playing computer games or watching TV, ask your mom and

 dad to play with you. Go outside together, or do some reading.

      Be kind. Little things might mean a lot to your mom or dad. You can brighten a parent's day with

 a hug (拥抱), a card , or a joke. It's also lovely when a kid cleans up his or her room without being

      Do your best at whatever you do. You don't have to be perfect, but when you do your best,
