Nowadays film cameras are going out of our life. Do you remember how it works? And do you know the difference between a film camera and a digital camera?
A film camera is a light-proof box, which all light can’t go through. It has a lens (镜头) system to focus light onto the film at the back of the camera.
Let’s suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. Light goes into the camera lens and hits the shutter (快门). In other words, nothing happens yet. Now let’s say that the dog looks really cute and you decide to take a picture. When you press the button, the shutter opens for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed (反向的) picture on the film. When you finish the roll (卷) of the film, you can take it to the photo shop to develop it and you will have a great picture!
Film cameras and digital cameras work in a similar way. In digital cameras, the light falls not on film but onto a sensor (传感器) called a CCD. This change light and color into a digital information or pixels (象素). The CCD is the heart of any digital camera and usually the most expensive part - depending on how good it is.

Of course Paul knew that he would wish he had a brother like that. But what the boy said surprised Paul greatly.
“I wish，”the boy went on，“that I could be a brother like that．”Then they got on the car.
After a short ride，the boy turned and with his eyes shining，said，“Paul，would you mind driving in front of my house？” Paul smiled a little and thought he wanted to show off. But Paul was wrong again.
"Will you stop where those two steps are？ the boy asked．

“There she is，Buddy，just like I told you upstairs. His brother gave it to him for Christmas and it didn’t cost him a cent. And some day I’m going to give you one just like it…then you can see for yourself all the nice things.”
