根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

How can a teen set themselves up for success? Here are some important points that you may find helpful.

Figure out your goals in life and work toward them. Start thinking about careers you would like to be in, but make a good choice based on your interests and strengths. 1 You could also work towards non-career related goals, such as creating your own fundraiser, getting good grades in school, joining in a team sport, etc. Challenge yourself and you’ll be surprised at what you can accomplish!

Don’t get into any trouble, legal or otherwise. It could ruin your future plans. Avoid the peer pressure and keep away from the cigarettes, alcohol, and drugs. 2 If you’re being pressured into anything, walk away. If you can avoid these things during your teen years, they’re a lot easier to avoid once you’re out of high school and away from peer pressure.

Have good friends to help you out! 3 Be with people who make you happy. Create a group of supportive, loving friends that can help you succeed in life and live your dreams. Find a few really good friends that will stick with you once you leave high school.

4 Join a sports team at school or out of school. Take your dog for a nice, long walk. Join a yoga group, go swimming at the local recreation center, or do sit-ups during commercial breaks on TV! Just exercise! 5 Studies show that people who are actively involved in activities in their teen years will be more active when they’re adults.

A. Get active!

B. Go for a run around your neighborhood.

C. This could be your job for the rest of your life!

D. You will start forming your own ideas this way.

E. It helps you feel better, mentally and physically.

F. Friends are there to support you and lift your spirits.

G. Obey the law and avoid ending up in the back of a police car.
