Many people are surprised when they find that the Internet was set up in the 1960s.At that time, computers were large and expensive. Computer networks(网络) didn’t’ t work well. If one computer in the network broke down, then the whole network stopped. So a new network system(系统) had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way the computer network system would keep on working all the time.
At first, the Internet was only used by the government, but, in the early
1970s, universities, hospitals and banks were allowed to use it too.However, computers were still expensive and the Internet was difficult to use. By the start of the 1990s, computers become cheaper and easier to use. Scientists had also developed software(软件) that made “surfing(浏览)” the Internet more convenient(方便).

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.The underlined word “light-proof” in the passage means “_____”.
A.不透明的 | B.不透风的 |
