that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself. Find an issue you are interested in and learn more. Volunteer or, if you can, contribute a little money to a cause. Whatever you do, don't be a bystander. Get involved. You may have the opportunity to make your biggest difference when you're older. But why not start now?

Our own experience working together on health, development, and energy the last twenty years has been one of the most rewarding parts of our lives. It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.

1. What does the underlined part in Paragraph 2 refer to?

A.Your life style. B.Your life value.

C.Your trouble in life. D.Your life experience.

解析：B细节理解题。根据文章第二段的内容"梦想着你会读心术，能洞穿墙壁，或者有超人的力量，这或许听起来很愚蠢，但事实上，这却是你内心深处认为人生最重要的东西"可知，画线部分的意思是"你人生中真正重要的东西"，即你的人生价值，故B项正确。

3. What does the author stress in Paragraph 5?

A.Learning more and contributing more to a cause.
