In every British town, large and small, you will find shops that sell second-hand goods. Sometimes such shops deal mostly in furniture, sometimes in books, sometimes in ornaments (装饰) and household goods, sometimes even in clothes.

　The furniture may often be "antique", and it may well have changed hands many times. It may also be very valuable, although the most valuable piece will usually go to the London salerooms, where one piece might well be sold for hundreds of thousands of pounds. As you look around these shops and see the polished wood of chests and tables, you cannot help thinking of those long-dead hands which polished that wood, of those now-closed eyes which once looked at these pieces with love.

　The books, too, may be antique and very precious; some may be rare first printings. Often when someone dies or has to move house, his books may all be sold, so that sometimes you may find whole libraries in one shop. On the border between England and Wales, there is a town which has become a huge bookshop as well. Even the cinema and castle have been taken over, and now books have replaced sheep as the town's main trade.

　There are also much more humble shops, sometimes simply called "junk shops", where you can buy small household pieces very cheaply. Sometimes the profits (利润) from these shops go to charity(慈善事业). Even these pieces, though, can make you feel sad; you think of those people who once treasured them, but who have moved on to another country or to death.

　Although the British do not worship(崇拜) their ancestors, they do treasure the past and the things of the past. This is true of houses as well. These days no one knocks them down; they are rebuilt until they are often better than new. In Britain, people do not buy something just because it is new. Old things are treasured for their proven worth; new things have to prove themselves before they are accepted.

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.

69．In the “Film cameras” part, you fail to take the picture of the dog because _____.

       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
