      Mom and Dad are two of the most important people in your life. Over your lifetime, they may

 influence you more than anyone else you will meet. So if your mom loves to read, you just might

 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

 asked. And if you try not to fight with your brothers or sisters, your parents will be so happy!

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

 you make your parents proud. It makes them happy to see how you're turning into a great kid. Why?

 Because it lets them know they're doing a good job.
