     Leonardo da Vinci was born on April 15, 1452 in Vinci, Italy. He was the illegitimate son of Ser Piero, a Florentine notary and landlord, but lived on the estate andwas treated as a legitimate son.
     In 1483, Leonardo da Vinci drew the first model of a helicopter. It did not look very much like our modern day “copter,” but the idea of what it could do was about the same.
     Leonardo was an artist and sculptor. He was very interested in motion and movement and tried to show it in his art. In order to show movement, he found it helpful to study the way things moved. One subject he liked to study was birds and how they flew. He spent many hours watching the birds and examining the structure of their wings. He noticed how they cupped air with their wings and how the feathers helped hold the air. Through these studies, Leonardo began to understand how birds were able to fly.
    Like many other men, Leonardo began to dream of the day when people would be able to fly. He designed a machine that used all the things he had learned about flight, and thus became the first model of a helicopter.
     Poor Leonardo had only one problem, however. He had no way to give the necessary speed to his invention. You see, motors had not yet been invented and speed 19 was an important part of the flying process. It would be another four hundred years before the engine was invented and another fifty years before it was put to the test in an airplane. Leonardo’s dream of a helicopter finally came to pass in 1936.
     The Italian painter, sculptor, architect, engineer, and scientist, Leonardo died on May 2, 1519, and was buried in the cloister of San Fiorentino in Amboise.

     Glass fibers are extremely strong; for their weight, they are stronger than steel. They are made by forcing molten glass through tiny holes called spinnerets. As many as four hundred spinnerets are placed together, and threads of glass much thinner than human hairs are drawn off at great speed-miles of thread per minute. As they speed along, the threads are coated thinly with a type of glue and twisted into a yarn.The glass fibers are used with plastics to make boats and car bodies. They are also woven into heavy cloth for window draperies and into strong belts for making tiresstronger.
     A special kind of glass fiber is causing a revolution in communications. A signal of light can be made to travel along the fiber for very long distances. By changing the quality of the light, many messages can be sent at once along one strand of glass. New office buildings are being “wired” with glass fibers as they are built. The glass fibers will be used to connect telephones and computers in ways that not long ago were eitherimpossible or too expensive.
     Glass wool traps air in a thick, light blanket of fibers. This blanket is then put into walls and ceilings to keep warm air in during the winter and cool air in during thesummer.
     To make glass wool, molten glass is fed into a spinning drum with many holes in it. As the glass threads stream out of the holes, they are forced downward by a blast of hot air and through a spray of glues. The threads are then further blown about to mix them up as they fall in a thick mat on a moving belt.
      The glass we see through and drink out of has many, many other uses besides the ones described here.

       For centuries, people have searched for a way to replace dead and decaying teeth with comfortable false teeth. Many materials have been used to make a set of false teeth. The teeth themselves should be made from a hard and durable material. They should be secured to a soft material, making them easy to wear. In the last two decades, dentists succeeded in making durable false teeth that are comfortable, too.
      Two thousand years ago, the Etruscans made teeth out of animal bone and gold. These materials were used-with varying degrees of success-up to the 1700’s. When George Washington was president, ivory from animals such as elephants became a popular material for false teeth. Doctors and inventors also tried silver, peal, and agate, but teeth made from these materials were very expensive. Perhaps the most successful material was porcelain, invented by a Frenchman about two hundred years ago. White, strong, and resistant to decay, porcelain is still used today for making single teeth.
     Besides finding a material for the teeth, inventors also had to find a way to secure them in a person’s mouth. People tried wire, springs, and many kinds of glue to accomplish this. In most cases, however, discomfort and a likelihood of the teeth falling out plagued the person who wore them.
      Around 1844, an American dentist named Horace Wells used laughing gas to put people to sleep before working on their teeth. This innovation made dental work a lot less painful. Soon after, an inventor created the first form of rubber. This was important to dentistry because teeth could be attached to the rubber, and the rubber could be molded to fit the shape of the mouth. With these two developments, dentist could work without causing pain and could fit teeth more carefully. False teeth have become more available and comfortable since then, and dentists have continued to improve the making and use of false teeth.

      The lens on a camera has only two tasks. First, it must gather in as much light as possible in order to activate the sensitive chemicals on the film. Second, it must organize the light rays so that they form a sharp image on the film. These may sound like simple tasks, but they are not.
      One of the sharpest lenses is merely a pinhole in a sheet of cardboard, metal, plastic, or a similar material. If the pinhole is tiny enough, the image can be quite sharp,  but then very little light is admitted. For most purposes, even the most sensitive film would take too long to record an image.
       A glass lens is much better because it lets in much more light and focuses it on the film. Yet simple glass lenses are sharpest only in their centers. As more of the lens is used, the image suffers in sharpness.
      One reason a simple lens can cause problems is that it is shaped like a section of a sphere. Spherical lenses do not focus perfectly on flat film, so the image is slightly distorted, especially at the edges. Another reason is that the lens can act partly like a prism. This means that some of the colors in the image will not focus properly, and the image will be fuzzy.
      One solution is to block off all but the sharp-focusing center of the lens. If you block off the edges of the lens, however, less light will get to the film. Early lenses had to compromise between sharpness and light-gathering power.
      Very sharp lenses that admit as much light as possible can be built by making them with several separate lenses, or elements. A multiple-element lens has from two to nine separate lenses. Some elements are cemented together, and some have a gap between them. Furthermore, the elements are often made of different kinds of glass, each with a different ability to bend light rays. Some of the elements are there just for correcting problems caused by the other elements! The results are worth it, though: pictures can be taken in many different light conditions, and they have a sharpness you
can almost feel.

34.   The word it in the first paragraph refers to:

35.   The word distorted in the fourth paragraph means:
A.Out of a proper or natural relation
B.Clean and in shape
C.Purified, as one

36.   In what ways does an image suffer if too large an area of the spherical lens is used?
A.The edges of the image become fuzzy
B.Too much light is admitted
C.Too little light is admitted
D.Colors change

37.   What is the main disadvantage of a simple lens that is made sharp by using just the center?
A.With less light-gathering power, the lens is utterly useless.
B.With less light-gathering power, the lens is useful only in bright light.
C.With more light-gathering power, the lens is useful only in dim light.
D.With more light-gathering power, the lens is utterly useless.

38.   The word sharpest in the third paragraph is closest in meaning to:
A.Having clear form and detail
B.Terminating in an edge or a point
C.Intellectually penetrating; astute
D.Having a thin edge or a fine point suitable for or capable of cutting or piercing
