DNA is in every cell ( 细 胞 ) of our bodies except for our red blood cells. It stores the information your body needs to make you who you are. Your DNA is 99.5% the same as everyone else on the planet. The 0.5% that we don't share with everyone else is the bit that makes you different.
DNA is the mysterious code ( 神秘密码 ) of life. It not only decides your gender ( 性别 ) and appearance, but also tells you about your family history, as well as your relations with people in other parts of the world.
Last fall, 20 students at Coretta Scott King Young Women's Leadership Academy in Atlanta learned more about who they are through a DNA test.
During their life sciences class, the girls took samples ( 样本) from their cheeks and sent them to Living DNA, a UK—based DNA testing company. From the test results, they learned about their ancestry ( 祖先 ) and made real-world connections to their races.
Lizbeth Islas, 12, learned about her family's Central American roots ( 根,根源 ) from her mother, who is Guatemalan ( 危地马拉人 ). She expected to share DNA with 54% of Native American people, but she was surprised to find that she also shared DNA with people living in Africa and Europe.
Elianed Guzman, 13, knew little about her family except that they were from Mexico. She was surprised to learn that she also shared DNA with people in China and Japan.
The girls gathered in small groups to wait for their results. Their reactions reached from confusion to surprise. The 13-year-old Amariah Caudle said she learned that "the color of your skin can't decide where you are from."
Diahan Southard, a manager from Living DNA, helped them understand the test results. "Does it change how you see yourself?" Southard asked.
"Now I know I have family from everywhere," said Jahtmya Phillips, 13. "Does it change how you see the girls around the table?" Southard asked. "We are all sisters," said Anike Akanni-Jenkins, 13.
Laura Pena, the school's class designer, said she hopes to add DNA testing to the school's ninth grade curriculum ( 课程 ) in the future. "This is not a lesson they will forget anytime soon," she said.

Imagine waking up at the age of six and discovering your family is missing! That's what happened to young Charles Mulli in his Kenyan house one morning. He soon realized he had been abandoned ( 抛弃 ) by his very poor parents and seven siblings!
The child was forced to become a street beggar ( 乞 讨 者 ) in order to make a living. Living a poor and hopeless life, he still dreamed of being an important man some day.
When Mulli turned 16, he walked for three days to Kenya's capital, Nairobi,in search of work. In the years that followed, he tried many difficult jobs.
Mulli saved his money and bought a car in 1971. In the same year, he started a transportation service. The company, called "Mullyways," became quite successful.
All of his hard work turned Mulli into a millionaire and an important man. Yet his life would soon take another surprising turn.
Mulli began considering the growing number of homeless children in Kenya. One day Mulli told his wife and children that he was to devote his life to taking care of street kids. Soon the Mulli House was filled with 100 orphans ( 孤 儿 ), but that was just the beginning! In 1989, Mulli and his wife opened the Mulli Children's Family (MCF). They provided children with food, clothes,medical care and an education. Most importantly, they offered something many of the kids had never experienced — parental love.
So far, MCF has helped more than 12,000 children through its MCF homes and community- based centers.

a valentine box

Mother said, "We'll see," and she continued eating.
What did "We'll see" mean? I had to have that box or my second grade Valentine's Day would be terrible. Maybe they didn't love me enough to help me with my_________.
All Saturday I waited_________ and with Sunday arriving, my worry
increased, but I knew an enquiry(询问)about the box might cause anger or loud voice, for in my house children only asked once. More than that_____________ trouble.
Late Sunday afternoon, my father called me into the kitchen. The table was covered with colorful paper of different kinds. A(n)_____________ shoebox rested on top of it. A heavy stone dropped when Daddy said, "Let's get started on your project."
In the next hour my father packed the shoebox into a surprising valentine box. Colorful paper covered the ugly cardboard with red hearts posted to what I considered all the right places. He sang while he worked. When he finished, he was so pleased that a broad smile spread over his face. "What do you think of that?" he asked.
