Dear John,

       I’m so glad to know that you are coming to Beijing.                                

       Real policemen , both in Britain and the United States, hardly recognize any similarity between their lives and what they see on TV—if they ever get home in time. There are similarities ,of course ,but the cops (policemen) don’t think much of them.

       The first difference is that a policeman’s real life revolves round（以……为中心）the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley（小巷）after someone he wants to talk to.

Little of his time is spent in chatting to charming ladies or in dramatic confrontations（对抗）with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilty —or not —of stupid crimes of little importance.

Most television crime drama is about finding the criminal：as soon as he’s arrested, the story is over. In real life, finding criminals is seldom much of a problem. Except in very serious cases like murders and terrorist attacks—where failure to produce results reflects on the standing of the police —little effort is spent on searching. The police have detailed machinery which eventually shows up most wanted men.

Having made an arrest, a detective really starts to work. He has to prove his case in court and to do that he often has to gather a lot of different evidence. Much of this has to be given by people who don’t want to get involved in a court case. So, as well as being overworked, a detective has to be out at all hours of the day and night interviewing his witnesses and persuading them, usually against their own best interests, to help him.

A third big difference between the drama detective and the real detective is that the real detective lives in an unpleasant moral twilight（暮色）. Detectives tend to have two opposing pressures：first, as members of a police force they always have to behave with absolute legality：secondly, as expensive public servants they have to get results. They can hardly ever do both. Most of the time, some of them have to break the rules in small ways.

If the detective has to deceive（欺骗）the world. The world often deceives him. Hardly anyone he meets tells him the truth. And this separation the detective feels between himself and the rest of the world is deepened by the simplemindedness — as he sees it —of citizens, social workers, doctors, law —makers, and judges, who, instead of putting a complete end to crime punish the criminals less strictly in the hope that this will make them reform. The result, detectives feel, is that nine —tenths of their work is re - catching people who should have stayed behind bars. This makes them rather cynical（愤世嫉俗的）.

In the late 1500s, a large powerful gun was placed on top of the Signal Hill, in Newfoundland, to prevent attacks from the outside. Flags were also flown there to warn sailors of bad weather. It's fitting, then, the Italian Gulielmo Marconi should have chosen this site（场所） to receive the world's first radio signal - in Morse code - from England on December 12, 1901.

    Marconi, combining earlier ideas with his own, led us to a new communications age. For the next 50 years, until the appearance of television, radio ruled the air waves.

    Today, it's the TV that rules. No single person can say to have invented television.

    In 1884, the German Paul Nipkow invented a device (设备) that sent pictures mechanically (机械地), and in 1906, Boris Rosing, a Russian, used a ray and a disc to create the world's first TV system. Then in the early 1920s, another Russian, Vladimir Zworykin，invented a picture display tube. He took out a patent (专利) for color TV, even though it wouldn't be developed for another 25 years.

    In 1924, a Scot entered the scene - John Logie Baird. He first succeeded in sending a moving picture and a year later got the first actual TV picture. In 1926, Baird showed TV in a London laboratory. Two years later in New York, Felix the Cat became the first TV star.

TV excited everyone's imagination, but hardly anyone had a set, with just two thousand in use worldwide in the mid-1930s.

Since the late 1940s, TV technology has developed very quickly. Computers may finally be combined with all televisions to give people a total all-in-one communications network.

Today, it's possible to sit and watch TV in the middle of a forest or in the Arctic. It's surpris-

ing when one considers that Marconi was on Signal Hill in the same century.

1．We can learn from the text that Signal Hill was once used as _________.

       A．a site of communication            

       B．a weather station

       C．a factory to produce weapons    

       D．a battle field to fight enemies from the outside

2．When the writer says that today it is the TV that rules, he means that the TV _________.

    A．has led to a new communications age

    B．is a major means of today's communication

       C．is a device invented with ideas from Marconi

       D．has replaced the radio in today’s communication

3．What is the main idea of Paragraphs 4 and 5?

       A．London is the pace where TV is invented.

       B．John Logie Baird was the chief inventor of television.

       C．A number of people contributed to the invention of television.

       D．Russian scientists played an important role in the invention of television.

4．The writer believes that the day will come when        .

       A．the future computers will be able to do the work TV is now doing

       B．the future computers will become available to everyone in the world

       C．the future computers will be connected to create one international network

       D．the future computers will take the place of televisions and radios

The first people who gave names to hurricanes were those who knew them best - the people of Puerto Rico. The small island of Puerto Rico is in the West Indies, off the coast of Florida. This is where all the hurricanes begin that strike the east coast of the United States. Often they pass near Puerto Rico or cross it on their way north. The people of Puerto Rico expect some of these unwelcome visitors every year. Each one is named after the Saint's Day on which it arrives. Two of the most destructive storms were the Santo Ana in 1840 and the San Ciriaco in 1899.

    Giving girls’ names to hurricanes is a fairly new idea. It all began with a story called "Storm", written by George Stewart in 1941. In it a weatherman amused himself by naming storms after girls he knew. He named one Maria. The story describes how she Maria grew and developed, and how she changed the lives of people when she struck the United States.

    Weathermen of the U.S. Army and Navy used the same system during World WarⅡ. They were studying weather conditions over the Pacific Ocean. One of their duties was to warn American ships and planes when a storm was coming. Whenever they spotted one, they gave it a girl's name. The first one of the year was given a name beginning with [A]. The second one got a name beginning with [B]. They used all the letters from A to W, and still the storms kept coming. They had to use three lists from A to W to have enough names to go around. This was the first list of hurricane names that followed the alphabet. It served as a model for the system the Weather Bureau (局) introduced in 1942.

    Before 1950 the Weather Bureau had no special system for naming hurricanes. When a hurricane was born down in the West Indies, the Weather Bureau simply collected information about it. It reported how fast the storm was moving and where it would go next. Weather reports warned people in the path of the hurricane, so that they could do whatever was necessary to protect themselves.

    This system worked out fine as long as weather reports talked about only one hurricane at a time. But one week in September 1950 there were three hurricanes at the same time. The things began to get confused. Some people got the hurricanes mixed up and didn't know which was which. This convinced the Weather Bureau that it needed a code for naming the storms in order to avoid confusion in the future.

1．Hurricanes were first named after the ________.

A．date on which they occurred                 B．place where they began

C．amount of destruction they did              D．particular feature they have

2．The practice of giving girls' names to hurricanes was started by __________.

      A．a radio operator                                   B．an author     

C．a sailor                                               D．local people

3．The purpose for which weathermen of the army and navy began using girls' names for hurri-

canes was __________.

     A．to keep information from the enemy

      B．to follow the standard method of the United States

      C．not given in the article

      D．to remember a certain girl

4．The Weather Bureau began naming hurricanes because it would help them __________.

       A．collect information more rapidly           B．warn people more efficiently

       C．make use of military (军事的) records D．remember them

    On the night of July 6,1943, a plane took off from an Air Force base in England to intercept (截击) German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a fantastic rate of speed. An old experienced flyer, he had never seen anything like them. Thinking they might be a new German weapon, he decided to give chase. But when he swung the plane around and headed directly for the lights, they disappeared.

Captain Nash may have been the first to see such orange lights but he wasn't the last. His experience was repeated many times by pilots during World WarⅡboth in Europe and the Far East. Pilots in the Korean War also reported seeing the strange lights.

What were they? No one knows for sure, but there is an interesting theory to account for them. According to this theory, the orange lights are space animals - animals specially adapted to life in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea.

These space animals, the theory says, live so far up in the atmosphere that they are not visible from earth. They feed partly on the air and partly on energy from sunlight. Being almost pure energy themselves, they can adjust their bodies to glow (发光) at night. During the day they become invisible.

Before World War II, continues the theory, there was little radiated (发射的) energy available on the earth's surface. Then came the development of rockets, atomic reactors (核反应堆), and hydroelectric plants (水力发电厂). The space creatures are attracted to these sources of energy of food. At night when there is no energy from sunlight, they go down into the lower levels in search of a meal. They may even drift into the range of human eyesight. This explains the fact that they have been sighted regularly from the earth since 1943.
