The making of glass is a very old industry—at least 4 500 years old. Glass has many extraordinary qualities and it is frequently being used in new ways. One of the most interesting new uses for glass is in telephone communication. Scientists have developed glass fibers as thin as human hair which are designed to carry light signals. When the light reaches the other end, it is first changed into electrical signals, which are in turn converted(转变) into sound messages. Called light wave communication， the new system was used successfully in an experiment in Chicago in 1977. During the experiment two glass fibers were able to carry 672 conversations at the same time. The light wave cable, containing 144 glass fibers, has the capacity(容量) to carry 50 000 conversations at the same time. The light wave communication system has two important advantages. First the glass fiber cables are smaller and weigh less than copper(铜) cables; second, they cost less.
1. One of the extraordinary qualities of glass is that it can carry_______.
A. any signal B. light signals
C. sound signals D. electrical signals
2. Before you can hear a message on the telephone using the new system_______.
A. the light signals have to be changed into electrical sound
B. neither the light nor the electrical signals have to be changed in any way
C. light must first be changed into electrical signals and then into sound
D. electrical signals must first be changed into light signals and then into sound
3. According to the passage the new telephone communication system_______.
A. was put on experiment in 1977
B. had been put into actual use by 1977
C. had been repeatedly experimented before 1977
D. was first put into actual use in 1977
4. From the passage, you can tell that people prefer glass fiber cables to copper cables because_______.
A. glass fiber is easier to make
B. glass fiber is less expensive
C. glass fiber is more up to date
D. glass fiber delivers messages directly
5. Which of the following statements best expresses the main idea of the passage?
A. Light signals have changed the use of glass in industry.
B. Glass fibers have reduced the cost of telephone communication.
C. Glass is very useful because it has many unusual qualities.
D. The use of glass fibers to carry telephone messages is an interesting new development.
提示：
Louis Armstrong had two famous nicknames (绰号). Some people called him Bagamo. They said his mouth looked like a large bag. Musicians often called him Pops, as a sign of respect for his influence (影响) on the world of music .
Born in 1901 in New Orleans, he grew up poor, but lived among great musicians. Jazz was invented in the city a few years before his birth. Armstrong often said,” Jazz and I grew up together.”
Armstrong showed a great talent (天赋) for music when he was taught to play the cornet (短号) at a boy’s home. In his late teens, Armstrong began to live the life of a musician. He played in parades, clubs, and on the steamboats that traveled on the Mississippi River. At that time, New Orleans was famous for the new music of jazz and was home to many great musicians. Armstrong learned from the older musicians and soon became respected as their equal.
In 1922 he went to Chicago. There, the tale of Louis Armstrong began. From then until the end of his life, Armstrong was celebrated and loved wherever he went. Armstrong had no equal when it came to playing the American popular song.
His cornet playing had a deep humanity (仁爱) and warmth that caused many listeners to say, “Listening to Pops just makes you feel good all over.” He was the father of the jazz style (风格) and also one of the best-known and most admired people in the world. His death, on July 6, 1971, was headline news around the world.

The Making of a Surgeon
How does a doctor recognize the point in time when he is finally a “surgeon”? As my year as chief resident （进修医生） drew to a close, I asked myself this question 36 more than one occasion．
The answer, I concluded, was 37 ．When you can say to yourself, “There is no surgical patient I cannot treat competently, treat just 38 or better than any other surgeon”-- then, and not until then, you are 39 a surgeon．I was 40 that point．
41 , for example, the emergency situations that we met almost every night．The first few months of the year I had 42 the ringing of the telephone．I knew it meant another critical decision to be 43 ．Often, after I had told Walt or Larry what to do in a particular 44 , I'd have trouble getting back to sleep．I'd 45 all the facts of the case and, often, wonder 46 I had made a poor decision．More than once at two or three in the 47 , after lying awake for an hour, I’d get out of 48 , dress and drive to the hospital to see the patient myself．It was the only 49 I could find the 50 of mind I needed to relax．
Now, in the last month of my residency, 51 was no longer a problem．Sometimes I still couldn’t be sure of my decision, but I had learned to 52 this as a constant problem for a surgeon．I knew that with my knowledge and experience, any decision I'd made was bound to be a 53 one．It was a nice feeling．
This all sounds conceited （自负的） and I guess it is -- 54 a surgeon needs conceit．He needs it to encourage him in trying moments when he's bothered by the 55 and uncertainties that are part of the practice of medicine．He has to feel that he's as good as and probably better than any other surgeon in the world．Call it conceit -- call it self-confidence; whatever it was, I had it．
