Large companies need a way to reach the savings of the public at large. The same problem, on a small scale, faces practically every company trying to develop new products and create new jobs. There can be little prospect of raising the sort of sums needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money on the permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business through the Stock Exchange. By doing so, they can put the saving of individuals and institutions into circulation both at home and overseas.
When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker（股票经纪人） to some other saver who is seeking to invest his money.
Many of the services needed both by industry and by each of us are provided by the government or by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could not function. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they, too, come to the Stock Exchange.
There is hardly a man or woman in this country whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another, the new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which these savings can reach those who need finance.

A. rely on their own resources
B. persuade the banks to provide long-term finance
C. borrow large sums of money from friends and people they know

A. repaid to its original owners as soon as possible

A. ask another company to obtain their money for them
B. look for other people to borrow money from

Just outside the northern Italian town of Bra, there rises a church tower with a clock that is a half hour slow. Though not far from the industrial city of Turin，Bra smells of roses，and leisure（悠闲）is the law. It is both the home of an international movement that promotes slow food and one of Italian cities that have joined the slow cities. In Bra, the population is 27，866. The town fathers have declared that all small food shops be closed every Thursday and Sunday. They forbid cars in the town square. All fruits and vegetables served in local schools must be organic（有机的）. And as the movement goes well，the slow concept gradually spreads across Europe.
The argument for a Slow Europe is not only that it is good，but also that it can work. The Slow City Movement, which started in 1999，has improved local economies（经济）by promoting local goods and tourism. Young Italians are moving from larger cities to Bra，where unemployment is only 5 percent，about half the nationwide rate. Slow food and wine festivals draw thousands of tourists every year. Shops are doing well，many with sales rising at a rate of 15% per year.“This is our answer to the world，”says Paolo Saturnini，the founder of Slow Cities.
France is in favor of slow economics. Most outsiders have long been doubtful of the French model：short hours and long vacations. Yet the French are more productive than those in the United States and Britain，and have been for years.
The mystery of French productivity has risen an Europe-wide debate about the advantages of working more slowly.

64．The low unemployment in Bra proves that__________.

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 open 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 colour 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.
67．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.
68．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 colour into a digital information
69．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
70．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
