Film cameras and digital cameras work in a similar way.
Film cameras
After all, a film camera is basically a light – proof (不透光的) box. 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. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let’s say that the dog looks really cute and you decide to snap a picture. What happens? 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)image on the film.
When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog!
Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them.
Digital cameras
In digital cameras, the light falls not on film but onto a sensor (传感器) called a CCD (Charge Coupled Device). This digitally converts(转变) 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.
68．Which of the following statements is TRUE?
A．Both digital and film cameras focus light onto the film.
B．All cameras have a sensor.
C．Digital cameras and film cameras have something in common. .
D．Small cameras usually have longer focal lengths.

A．light goes into the camera lens and hits the shutter
B．you haven’t aimed the camera at the dog
C．the image of the dog is not created
D．the sensor fails to convert light and color into a digital information
70．The main reason that sports photographers can get clear and big photos of players is that _ ___.
A．they use digital cameras B．the lens of their cameras is excellent
C．their focus lenses are short D．their focus lenses are long
71．Generally speaking, a digital camera’s price is ____.
A．closely related to the quality of the CCD
B．irrelevant to the quality of the CCD
C．closely related to the lens
D．irrelevant to the lens
Music is an international language. The songs that are sung or played by instruments are beautiful to all people everywhere.
Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the streets.
Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, politics, and activities of the American people. Most of the radio broadcast is music.
Pop or popular music singers make much money. They make a CD or tape which radio stations use in every state. Once the popular singer is heard throughout the country, young people buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.
There are other kinds of music that are important to Americans. One is called folk music. It tells stories about the common life of Americans. Another is called western or country music. This was started by cowboys who would sing at night to the cows they were watching. Today, any music about country life and the love between a country boy and his girl is called western or country music.
Serious music for the concert halls is called classical music. Music for instruments is called orchestra music(管弦乐),such as the symphonies(交响乐) of Beethoven. There is opera for singers. There is ballet(芭蕾舞乐曲) for dancers like the story of Liang Shanbo and Zhu Yingtai in China.

The Internet has opened up a whole new on line world for us to meet, chat and go where we’ve never been before.
But just as in face to face communication, there are some basic rules of behavior that should be followed when on line. The basic rule is simple: treat others in the same way you would want to be treated. Imagine how you’d feel if you were in the other person’s shoes.
For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” If the answer is no, rewrite and reread. Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face.
If someone in the chat room is rude to you, your instinct（本能）is to fire back in the same manner. But try not to do so. You should either ignore the person, or use your chat software to block their messages. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.
Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you license to correct everyone else.
If you do decide to tell someone about a mistake, point it out politely. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.
It is not polite to ask others personal questions such as their age, sex, and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.

Everybody knows that words can carry messages. People communicate with words. Books, magazines, TV ，radio and films all help us to know what is going on in the world and what people are thinking about.
Do you think you can communicate without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad. When you put up your hand in class, the teacher knows that you say something or ask a question. You shake your head, and people know you are saying “No”. You nod and people know you are saying “Yes”.
Other things can also carry messages. For example, a sign at the bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs on doors tell you where to go in or out. Have you ever noticed there are a lot of signs around you and you receive messages from them all the time?
