第5题

Between the eighth and eleventh centuries A. D, the Byzantine Empire staged an almost un-

paralleled economic and cultural revival, a recovery that is all the more striking because it followed a long period of severe internal decline. By the early eighth century, the empire had lost roughly two thirds of the territory it had possessed in the year 600, and its remaining area was being raided by Arabs and Bulgarians, who at times threatened to take Constantinople and extinguish the empire altogether. The wealth of the state and its subjects was greatly diminished and artistic and literary production had virtually ceased. By the early eleventh century, however, the empire had regained al- most half of its lost possessions, its new frontiers were secure, and its influence extended far beyond its borders. The economy had recovered, the treasury was full, and art and scholarship had advanced.

To consider the Byzantine military, cultural, and economic advances as differentiated aspects of a single phenomenon is reasonable. After all, these three forms of progress have gone together in a number of states and civilizations. Rome under Augustus and fifth-century Athens provide the most obvious examples in antiquity.

Moreover, an examination of the apparent sequential connections among military, economic, and cultural forms of progress might help explain the dynamics of historical change. The common explanation of these apparent connections in the case of Byzantium would run like this: when the empire had turned back enemy raids on its own territory and had begun to raid and conquer enemy territory, Byzantine resources naturally expanded and more money became available to patronize art and literature. Therefore, Byzantine military achievements led to economic advances, which in turn led to cultural revival.

No doubt this hypothetical pattern did apply at times during the course of the recovery. Yet it is not clear that military advances invariably came first. Economic advances second and intellectual advances third. In the 860's the Byzantine Empire began to recover from Arab incursions so that by 872 the military balance with the Abbasid Caliphate had been permanently altered in the empire's favor. The beginning of the empire's economic revival, however, can be placed between 810 and 830. Finally, the Byzantine revival of learning appears to have begun even earlier. A number of notable scholars and writers appeared by 788 and, by the last decade of the eighth century, a cultural revival was in full bloom, a revival that lasted until the fall of Constantinople in 1453. Thus the commonly expected order of military revival followed by economic and then by cultural recovery was reversed in Byzantium. In fact, the revival of Byzantine learning may itself have influenced the subsequent economic and military expansion.

The primary purpose of the second paragraph is which of the following？

A．To show that Augustan Rome and fifth-century Athens are examples of cultural, economic, and military expansion against which all subsequent cases must be measured.

B．To suggest that cultural, economic and military advances have tended to be closely interrelated in different societies.

C．To argue that, while the revivals of Augustan Rome and fifth-century Athens were similar, they are unrelated to other historical examples.

D．To indicate that, wherever possible, historians should seek to make comparisons with the earliest chronological examples of revival.

听力原文：There are many reasons why family life in Britain has changed so much in the last

听力原文： There are many reasons why family life in Britain has changed so much in the last 50 years. The liberation of women in the early part of the 20th century and social and economic effects of the World War Two had a great impact on traditional family life. Women became essential to industry and the professions. During the war, they had worked in factories and proved their worth. Now, with the loss of millions of men, their services were indispensable to the nation. More recently great advances in scientific knowledge, and particularly in medicine have had enormous social consequences. Children are better cared for and are far healthier. Infant death rate is low. Above all, parents can now plan the size of their family if they wish through more effective means of birth control. Different attitudes to religion, authority and tradition generally have also greatly contributed to changes in family life. But these developments have affected all aspects of society. It is particularly interesting to know that the concept of the family as a social unit has survived all these challenges.

(30)

A．The liberation movement of British women.

B．Rapid economic development in Britain.

C．Changing attitudes to family life.

D．Reasons for changes in family life in Britain.

The history of technology is at least as old as humankind, if not older. Primitive too

ls have been discovered with almost every find of ancient human remains. Archaeologists (考古学家)have uncovered tools made by humanity's ancestors more than two million years ago, and the earliest direct evidence of tool usage, found in the Great Rift Valley, dates back to 2.5 million years ago. The hunter-gatherer lifestyle, characteristic of the Lower Paleolithic era, involved a limited use of technology, and the earliest tools, were developed to aid early humans in that role.

The discovery and utilization of fire, a simple energy source with many profound uses, was a turning point in the technological evolution of mankind. The exact date of its discovery is not known; evidence of burnt animal bones at the Cradle of Humankind suggests that the domestication of fire occurred before 1,000,000BCE; scholarly consensus indicates that Homo erectus had controlled fire by between 500,000BCE and 400,000BCE. Fire, fueled with wood and charcoal, allowed early humans to cook their food to increase its digestibility, thereby improving its nutrient value and broadening the number of foods that could be eaten.

Other technological advances made during the Paleolithic (旧石器时代的)era were clothing andshelter; the adoption ofboth technologies cannot be dated exactly, but they were key to humanity's progress.

As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as 380,000BCE, humans were constructing temporary wood huts. Clothing, adapted from the fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa by 200,000BCE and into other continents.

1.Which of the following statements is NOT true about the tools？()

A.The earliest tools were developed to aid early humans.

B.The earliest direct evidence of tool usage dates back to 2.5 million years ago.

C.The history of primitive tools is older than humankind.

D.Archaeologists have uncovered tools made more than two million years ago.

2.The turning point in the technological evolution of mankind is.()

A.the use of primitive tools by humanity ancestors

B.the adaptation of clothing from the fur and hides of hunted animals

C.the discovery and utilization of fire

D.the construction of temporary wood huts

3.The technological advances in clothing and shelter.()

A.were very important to humanity's progress

B.can be dated exactly

C.can be dated as early as 380,000BCE

D.helped people to move to any places they like

4.Which of the following can best replace the word "hides” in the third paragraph？()

A.leathers

B.hairs

C.places

D.skins

5.Which of the following is the best title for this passage？()

A.The discovery and utilization of fire.

B.The discovery of primitive tools.

C.The prehistory of technology.

D.The technological evolution of mankind.

In our society, we must communicate with other people. A great deal of communication is pe

rformed on a person-to-person basis by the simple means of speech. If we travel in buses or stand in football match queues, we are likely to have conversations in which we give information or opinions, and sometimes have our views challenged by other members of society. Face-to-face contact is by no means the only form. of communication and during the last two hundred years the art of mass communication has become one of the dominating factors of contemporary society. Two things above others have caused the enormous growth of the communication industry. Firstly, inventiveness has led to advances in printing, photography, and so on. Secondly, speed has revolutionized the transmission and reception of communications so that local news often takes a back seat to national news. No longer is the possession of information confined to a privileged minority. Forty years ago people used to flock to the cinema, but now far more people sit at home and turn on the TV to watch a program that is being channeled into millions of homes. Communication is no longer merely concerned with the transmission of information. The modern communications industry influences the way people live in society and broadens their horizons by allowing access to information, education and entertainment. The printing, broadcasting and advertising industries are all involved with their informing, educating and entertaining functions. Although a great deal of the material communicated by the mass media is very valuable to the individual and to the society of which he is a part, the vast modern network of communications is open to abuse. However, the mass media are with us for better, for worse, and there is no turning back.

The author probably means that speech on a person-to-person basis is the______means of communication.

A．primary

B．secondary

C．auxiliary

D．optional
