The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets its light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light had burned out. Others are still bright, but they are so far away that we cannot see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life giving star.

Dear Malia and Sasha,
I know that you’ve both had a lot of fun these two years. You have been to many picnics and had all kinds of junk food your mother and I probably shouldn’t have let you eat. But I also know that it hasn’t always been easy for you and Mom. So now I want to tell you a little more about why I decided to take our family on this journey.
When I was a young man, I thought life was all about me—about how I'd make my way in the world, become successful, and get the things I want. But then the two of you came into my world with those smiles and suddenly, all my big plans didn’t seem so important any more. I soon found that the greatest happiness in my life was that you were so happy. And I realized that my own life wouldn't mean much if I couldn’t make you two happy. In the end, girls, I ran for(竞选)President: Because of what I want for you and for every child in the US.
I want all our children to go to school so that they can learn and grow. I want them to have the chance to go to college—even though their parents don’t have enough money. And I want them to get good jobs.
I want us to see new technologies and inventions that improve our lives and make our earth cleaner and safer. And I want us to see no difference of different colors and areas because we are all equal.
I hope both of you will start to give others the chances you’ve had. You know, this country has given our family so much, so you have to, and really should, give something back. When you are doing something larger than yourself, you will realize how helpful you are.
These are the things I want for you—to grow up in a world in which you can make your dreams come true. And I want every child to have the same chances to learn and dream and grow and get what you girls have. That's why I've taken our family on this great adventure.
I am so proud of you. I love you more than you can ever know. And I am thankful every day because you behave so well when we get ready to start our new life together in the White House.
Love,
Dad
