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.

In the 1500s, South American fishermen said that the sea became warmer every few years. They gave this special event a Spanish name ’El Nino’, meaning ’the baby’. It is called ’the baby’ because it arrives around Christmas.
El Nino is a huge area of warm water in the middle of cold water in the Pacific Ocean. It happens every two to seven years. It moves around the ocean and becomes bigger and smaller at different times. This warm water affects the weather. It is always raining over El Nino. El Nino contains a lot of energy. Scientists think this energy is formed when wind comes from the northern half of the world. The winds blow across warm sea water in the south. When the strong wind hits the warm water, violent weather happens. Scientists think that El Nino existed for many thousands of years.
El Nino affects every person in the world because it affects the entire world’s weather. It can bring the rain that farmers need. It can bring storms that destroy homes. It can mean that fishermen cannot catch fish, and it can bring floods. There is nothing we can do about El Nino. It is an event of nature. We can help the world’s weather by trying to stop the greenhouse effect and air pollution. The most important job for scientists is to learn how to predict when El Nino is going to bring dangerous weather. Then, people can try to prepare for storms, floods and droughts. New technology like satellite pictures and temperature measuring equipment can help. Still, it is very hard to say when or where El Nino will cause damage.El Nino is ______.
| A．a storm that hits every two years | B．a huge area of warm water |

It happens ______.

| A．makes the weather better | B．affects the weather |
| C．gives the weather energy | D．predicts the weather |
It is always______ over EI Nino.
| A．sunny | B．cloudy | C．rainy | D．windy |
El Nino affects ______.
| A．everybody | B．just farmers |
| C．only fishermen | D．only students |

| A．finding out more about El Nino | B．being careful during the floods |
| C．driving cars | D．stopping the greenhouse effect |
