听力原文：Paper is one of the most important products ever invented by man. Widespread use

听力原文： Paper is one of the most important products ever invented by man. Widespread use of written language would not have been possible without some cheap and practical material to write on. The invention of paper meant that more people could be educated because more books could be printed and distributed. Together with the printing press, paper provided an extremely important way to communicate knowledge.

How much paper do you use every year？ Probably you cannot answer that question quickly. In 1900 the world's use of paper was about one kilogram for each person a year. Now some countries use as much as 50 kilograms of paper for each person a year. Countries like the United States, England and Sweden use more paper than other countries.

Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before the year 1400. The Egyptians wrote on a kind of material made of a water plant. Europeans used parchment for many hundreds of years. Parch-ment was very strong; it was made from the skin of certain young animals. We have learnt of the most important facts of European history from records that were kept on parchment.

(29)

A．More jobs could be provided than before.

B．More people could be educated than before.

C．More books could be printed and distributed.

D．More ways could be used to exchange knowledge.

听力原文： Movies are the most popular form. of entertainment for millions of Americans. They go to the movies to escape their normal everyday existence and to experience a life more exciting than their own. They may choose to see a particular film because they like the actors or because they've heard the film has a good story. But the main reason why people go to the movies is to escape. Sitting in a dark theatre, watching the images on the screen, they enter another world that is very real to them. They become involved in the lives of the characters in the movie, and for two hours, they forget all about their own problems. They are in a dream world where things often appear to he more romantic and beautiful than in real life. The biggest "dream factories" are in Hollywood, the capital of the film industry. Each year, Hollywood studios make hundreds of movies that are shown all over the world.

American movies are popular because they tell interesting stories and they are well-made. They provide the public with heroes who do things the average person would like to do but often can't. People have to cope with many problems and frustrations in real life, so they feel encouraged when they see the "good guys" win in the movies.

(20)

A．To enjoy a good story.

B．To see the actors and actresses.

C．To experience an exciting life.

D．To escape their everyday life.

As he wiped sweat from his face on a crowded bus, Wang Jun spoke angrily, " it is simply t

oo hot today. They say it is 35 degrees, but who believes them？"

Mr. Wang, a retired worker, was echoing the feelings of thousands of Beijing people as summer entered its hottest stage.

Thursday was the hottest day of the year so far, with the temperature officially reported as 36 degrees. But many people believe the government understates the real figure because regulations (条例 ) passed in the 1950s allow workers to stay at home for all or half day if the temperature is higher than 38 degrees.

" It was at least 40 degrees on Thursday, " said Liang Guojun, a middle school teacher. " It was unbearable. But the newspaper said only 36 and forecast rain. Of which there was none.

In Beijing, visitors to Daguanyuan Park in the southwest of the city said the ground temperature reached 55 degrees on Thursday.

The Beijing Evening News reported yesterday that more than 3 , 000 people had been admitted to hospitals suffering from heat stroke (中暑) , while local power companies were struggling to meet the demand for electricity.

A heat wave is sweeping much of the mainland, with temperatures in parts of Beijing, Shandong and Hebei provinces reaching as high as 39 degrees. Xinhua said the average temperature in Beijing on Thursday was 36 degrees but in the northern part of Tanghe Kou it was 39 degrees.

Hundreds of people suffering fevers were treated at hospitals. The Chaoyang hospital in northeast Beijing reported 55 such cases on Wednesday. They said most were caused by the difference in temperature between air-conditioned areas and outdoors.

Mr. Liang said the regulation on stopping work when the temperature reached 38 degrees was passed in the 1950s when Beijing had no air-conditioning and depended on fans—either handheld or electric.

"But in those days the temperature rarely reached 38 degrees, so the rule was not actually used. Now we have had years of global warming and industrial pollution and the summers get hotter each year, which means that the temperature is often higher than 38.

But an official from the Beijing Meteorological Observatory (北京气象台) said they had no knowledge of any such regulation.

Whom does the underlined word "they" (Paragraph 1) refer to？

A．Bus drivers.

B．Weather reports.

C．Newspaper editors.

D．Passengers on the bus.
