     After Maggie Doyne graduated from high school, she decided to spend a year traveling the world before

starting college. The journey changed her life and the lives of hundreds of orphaned children forever.

     In 2006, Doyne took a trip in Nepal, Asia. Having grown up in New Jersey, Doyne was shocked to see

so many orphaned children living on the streets. She wanted to do something about it. Doyne used her savings

to buy an acre of land. Then, she built the kids a home, the Kopila Valley Children's Home.

     Now, the Do Something foundation is doing something for Doyne. The organization provides resources

and support for teens that want to make a difference in the world. On Thursday night, the foundation named

Doyne the $100,000 prize winner of the 2009 Do Something Award.

     The Kopila Valley Children's Home officially opened its doors in 2008. Doyne, now 22 years old, cares for

26 kids. She has helped more than 700 other orphans find families. She also runs a program that provides

scholarships for needy families to send their children to school. The children learn basic skills such as sewing

and cooking. They also grow their own food in their garden and raise farm animals.

     Doyne admits that she didn't have it all figured out when she first arrived in Nepal. "I just felt that there

was something there for me," she said. Her parents were supportive of her. But it was a challenge to convince

other adults that an 18-year-old girl could accomplish such a big project. Still, Doyne never gave up on fund

raising. In just over a year, she had enough money to build her dream home.

     "When all the kids are sitting at the table for breakfast, or they're happy and all dancing... it's the best feeling

in the world." she says.

甜菜的上部叶片垂直生长，叶簇呈漏斗形，这种生长方式所形成的叶面空间的配制结构，极有力于光照的吸收，提高植株和群体的光合效率。而车前草的叶片是轮生的，叶片夹角为137.5度，这正是圆的黄金分割的弦角，叶片按照这个角度生长，可以充分利用光照。梨树随着树干长高，叶片沿对数螺旋上升，每个叶片都不会遮蔽下面的叶片。这段文字意在说明：

A．光照吸收率是影响植物生长的关键因素

B．暗合数学规律的叶片结构对植物生长有利

C．不同的生长环境造成了植物叶片生长的差异

D．对光照的吸收影响叶片的生长角度
