If you ask anyone who invented television, they will tell you that it was John Logie Baird. While Baird was, of course, extremely important in the history of television, it would be more accurate to see his role as part of a (31) _____ of events which finally led to television as we know it today.

The history of television really begins in 1817 with the discovery by Berzelius, a Swedish chemist, of the chemical selenium. It was found that the amount of electric current that selenium could carry depended on how much light struck it.

This discovery directly led to G. R. Carey, an American inventor, (32) _____ up with the first real television system in 1875. His system used selenium to transmit a picture along wires to a row of light bulbs. This picture was not very clear, however.

Over the next few years, a number of scientists and inventors simplified and improved on Carey's system. It was not until1923 that Baird made the first practical transmission. Once again, the picture was (33) _____ through wires, but it was much clearer than Carey's had been almost fifty years before.

The Second World War (34)  _____the development of television. After the war, television sets began to flood the market, with the first mass TV audience watching the baseball World Series in the USA in 1947. Within a few years, television had captured the (35) _____ of the whole world.

Read the following passage and mark the letter A, B, C, D on your answer sheet to indicate the correct answer to each of the questions from 35 to 41.

Stars have been significant features in the design of many United States coins and their number has varied from one to forty-eight stars. Most of the coins issued from about 1799 to the early years of the twentieth century bore thirteen stars representing the thirteen original colonies.

Curiously enough, the first American silver coins, issued in 1794, had fifteen stars because by that time Vermont and Kentucky has joined the Union. At that time it was apparently the intention of mint officials to add a star for each new state. Following the admission of Tennessee in 1796, for example, some varieties of half dimes, dimes, and half-dollars were produced with sixteen starts.

As more states were admitted to the Union, however, it quickly became apparent that this scheme would not prove practical and the coins from A798 on were issued with only thirteen stars-one for each of the original colonies. Due to an error at the mint, one variety of the A828 half cent was issued with only twelve stars. There is also a variety of the large cent with only A2 stars, but this is the result of a die break and is not a true error.

Why was a coin produced in 1828 with only twelve stars?

A. There was a change in design policy

B. There were twelve states at the time

C. The mint made a mistak

D. Tennessee had left the Union

Few men have influenced the development of American English to the extent that Noah Webster did. Born in West Hartford, Connecticut, in 1758, his name has become synonymous with American dictionaries. Graduated from Yale in 1778, he was admitted to the bar in 1781 and thereafter began to practice law in Hartford. Later, when he turned to teaching, he discovered how  inadequate the available schoolbooks were for the children of a new and independent nation.

In response to the need for truly American textbooks, Webster published A Grammatical Institute of the English Language, a three-volume work that consisted of a speller, a grammar, and a reader. The first volume, which was generally known as The American Spelling Book, was so popular that eventually it sold more than 80 million copies and provided him with a considerable income for the rest of his life. While teaching, Webster began work on the Compendious Dictionary of the English Language, which was published in 1806.

In 1807 Noah Webster began his greatest work, An American Dictionary of the English Language. In preparing the manuscript, he devoted ten years to the study of English and its relationship to other languages and seven more years to the writing itself. Published in two volumes in 1828, An American Dictionary of the English Language has become the recognized authority for usage in the United States. Webster‟s purpose in writing it was to demonstrate that the American language was developing distinct meanings, pronunciation, and spellings from those of British English. He is responsible for advancing simplified spelling forms: develop instead of the British form develope; theater and center instead of theatre and centre; color and honor instead of colour and honour.

In 1840 Webster brought out a second edition of his dictionary, which included 70,000 entries instead of the original 38,000. This edition has served as the basis for many revisions that have been produced under the Webster name.

Why did Webster write A Grammatical Institute of the English Language?

A. He felt that British books were not appropriate for American children.

B. American children at that time did not know how to spell. 

C. He wanted to supplement his income. 

D. There were no books available after the Revolutionary War.

The first two decades of this century were dominated by the microbe hunters. These hunters had tracked down one after another of the microbes responsible for the most dreaded scourges of many centuries: tuberculosis, cholera, diphtheria. But there remained some terrible diseases for which no microbe could be incriminated: scurvy, pellagra, rickets, beriberi. Then it was discovered that these diseases were Câused by the lack of vitamins, a trace substance in the diet. The diseases could be prevented or cured by consuming foods that contained the vitamins. And so in the decades of the 1920‟s and 1930‟s, nutrition became a science and the vitamin hunters replaced the microbe hunters.

In the 1940‟s and 1950‟s, biochemists strived to learn why each of the vitamins was essential for health. They discovered that key enzymes in metabolism depend on one or another of the vitamins as coenzymes to perform the chemistry that provides cells with energy for growth and function. Now, these enzyme hunters occupied center stage.

You are aware that the enzymes hunters have been replaced by a new breed of hunters who are tracking genes – the blueprints for each of the enzymes – and are discovering the defective genes that Câuse inherited diseases – diabetes, cystic fibrosis. These gene hunters, or genetic engineers, use recombinant DNA technology to identify and clone genes and introduce them into bacterial cells and plants to create factories for the massive production of hormones and vaccines for medicine and for better crops for agriculture. Biotechnology has become a multibillion-dollar industry.

In view of the inexorable progress in science, we can expect that the gene hunters will be replaced in the spotlight. When and by whom? Which kind of hunter will dominate the scene in the last decade of our century and in the early decades of the next? I wonder whether the hunters who will occupy the spotlight will be neurobiologists who apply the techniques of the enzyme and gene hunters to the functions of the brain. What to call them? The head hunters. I will return to them later.

The author implies that the most important medical research topic of the future will be ___________ 

A. the structure of genes 

B. inherited diseases 

C. the functions of the brain 

D. the operation of vitamins
