Listen to the passages carefully and then answer

16、 the questions that follow. 1 【听力原文】 We have no idea about when men first began to use salt, but we do know that it has been used in many different ways throughout history. For example, it has been recorded in many history books that people who lived over three thousand years ago ate salted fish. Th

17、ousands of years ago in Egypt, salt was used to preserve the dead. In some periods of history, a person who stole salt was thought to have broken the law. Take the eighteenth century for example. If a person was caught stealing salt, he would be thrown into prison. History also records that only in

18、England about ten thousand people were put into prison during that century for stealing salt! About four hundred and fifty years ago, in the year 1553, if a man took more than his share of salt, he would be thought to have broken the law and would be seriously punished, and his ear would be cut off.

21、y of the innovations in fire fighting that we will be seeing today were developed right here in America. As you can see from these photos, one of the earliest steam powered fire engines, the Joe Ross, was built in 1850 and operated right here in Cincinnati. Driven by four large horses, the ten-ton m

22、achine was steered by a single front wheel that was attached directly to the horse team. The steam motor on the Joe Ross was used to power the water pump that the big machine used to fight fires. Over here, we have an actual truck which was built in 1900 by the Waterous Fire Engine Works of Minneapo

23、lis. This was the very first fire engine to utilize a single steam motor for pulling the engine as well as pumping the water. As you may notice at the top of the truck, there is a circular platform that holds one end of a long ladder; the revolving platform operates almost like a record turntable in

24、 order to make it easier for ladder-operators to access buildings from difficult angles. The idea of the ladder turntable is credited to a San Francisco fireman by the name of Daniel Hayes.

26、ing this century, archaeologists have discovered that trees can be a valuable tool for measuring time. In scientific terms, this method is called dendrochronology. Dendrochronology is based on the scientific discovery that each year a tree grows a new layer of wood. When you cut down a tree, for exa

27、mple, you can see and count the layers of concentric circles. The layers vary in color and in thickness. These variations are a result of differing climate conditions from year to year that affects the growth of the annual rings. Cold weather, for example, creates thinner and lighter rings while hot

28、 weather produces thicker and darker rings. All trees that grow in the same region will have roughly the same pattern of annual rings, and this can be used as a source of comparison and measurement. Early in this century, archaeologists began using the rings to date ruined structures and figures bui

29、lt in the southwestern United States. They did this by comparing the rings of the wood found in the ruins with the rings of recently cut trees. Slowly but surely, the system was extended backwards in time to measure older ruins. The heavy forestry of the United States, coupled with the relative yout

31、l Defoe(about 1660-1731)was an important novelist in the English literature. When he was young, he served as a soldier and had been to Spain, Italy, France and Germany. At the same time, he went in for politics. He cared much about the development of capitalism. He wrote a lot of articles against it

32、 and he was put into prison twice for that. It was not until he was nearly sixty that he began to write the famous novel Robinson Crusoe, which was published in May, 1719. It spread so rapidly that the story was known to every household very soon. Robinson Crusoe can be divided into three parts. The

33、 first part is about Crusoes three voyages, the second about his hunting, hiding in caves, farming and his hard struggles against nature on a small deserted island, the third is about the things which happened after his return from the deserted island. The second part is the body of the novel, in wh

34、ich Robinsons characters are clearly shown. Defoe wrote his novel in a simple style and his language is easy to understand. His novel writing set a milestone of the modern English novel.

36、g been a subject of discussion among e-conomists. It has been argued that the supply of good land is limited. To feed a large population, inferior land must be cultivated and the good land worked intensively. Thus, each person produces less and this means a lower average income that could be obtaine

37、d with a smaller population. Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify them. One of the difficulties in carryin

38、g out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In a developing country where a vastly expanded population is pressing h

39、ard upon the limits of food, space and natural resources, it will be the first concern of government to place a limit on the birthrate. In a highly industrialized society the problem may be more complex. A decreasing birthrate may lead to unemployment. When the pressure of population on housing decl

40、ines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline. 13 【正确答案】 D 【试题解析】 细节题。文章开头讲到由于人口数量大，对土质不好的田地也要进行耕作，对良

42、不景气的问题。故选 B。 【知识模块】 短文听力 17 【听力原文】 Most people think of astronomers as people who spend their time in cold observatories peering through telescopes every night. In fact, a typical astronomer spends most of his/her time analyzing data and may only be at the telescope for a few weeks of the year. Some

43、 astronomers work on purely theoretical problems and never use a telescope at all. You might not know how rarely images are viewed directly through telescopes. The most common way to observe the skies is to photograph them. The process is very simple. First a photographic plate is coated with a ligh

44、t-sensitive material. The plate is positioned so that the image received by the telescope is recorded on it. Then the image can be developed, enlarged and published so that many people can study it. Because most astronomical objects are very remote, the light we receive from them is rather feeble. B

45、ut by using a telescope as a camera, 1ong time exposures can be made. In this way, objects that are a hundred times too faint to be seen can be photographed by just looking through a telescope. 17 【正确答案】 A 【试题解析】 细节题。原文说 “大部分人都认为天文学家就是每个晚上都在冰冷的天文台用望远 镜观察天空的人 ”。故 A项符合题意。 【知识模块】 短文听力 18 【正确答案】 C 【试题解析】 细节题。文章指出通过对天空拍照，照片可以被冲洗出来，并被放大和发表，这样就可以有很多人来参与研究。故选 C项。 【知识模块】 短文听力 19 【正确答案】 D 【试题解析】 细节归纳题。文中说照相平盘可以记录下由望远镜捕捉到的物体，然后把其拍成照片，故 D项意思正确。 【知识模块】 短文听力 20 【正确答案】 B 【试题解析】 细节题。文章后面讲到由于大部分天体距离 很远，所以我们能捕捉到的它们所发出的光线也很微弱，但如果用望远镜充当照相机就可以进行长时间曝光，以此将物体拍下来。故 B项正确。 【知识模块】 短文听力
