1、【题目】The discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called “the heroic age of Antarctic exploration”. By their tremendous heroism, men such as Shakleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogsthat earlier discoverers found so invaluable and hardly comparable.
Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the maping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper,coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes.
The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day. Present flying routes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey.
The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that they survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the consequences that ordinary and extraordinary sickness and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the latter keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world.
Plans are already on foot to set up permanent bases on the shores of this continent, and what so few years ago was regarded as a “dead continent” now promises to be a most active center of human life and endeavor.
1.When did man begin to explore the Antarctic?
A.About 100years ago.
B.In this century.
C.At the beginning of the 19th century.
D.In 1798.
2.What must the explorers be, even though they have modern equipment and techniques?
A.Brave and tough
B.Stubborn and arrogant.
C.Well-liked and humorous.
D.Stout and smart.
3.The most healthy climate in the world is___.
A.in South America.
B.in the Arctic Region.
C.in the Antarctic Continent.
D.in the Atlantic Ocean.
4.What kind of metals and minerals can we find in the Antarctic?
A.Magnetite, coal and ores.
B.Copper, coal and uranium.
C.Silver, natural gas and uranium.
D.Aluminum, copper and natural gas.
5.What is planned for the continent?
A.Building dams along the coasts.
B.Setting up several summer resorts along the coasts.
C.Mapping the coast and whole territory.
D.Setting up permanent bases on the coasts.

1、【题目】Part V Writing
Directions: For this part, you are allowed 30 minutes to write a composition on the topic: Keeping Fit. You should write at least 100—120 words and you should base your composition on the outline (given in Chinese) below:
1、保持健康的重要性;
2、保持健康的有效途径;
3、我的做法。
答案：
Keeping Fit
Obviously, health is more important than anything else we have in this world. Good health is a necessity for us to enjoy our life and pursue our dreams in the society. On the other hand, poor health may lead to poor chances in our career, making us pessimistic about our future. In other words, good health means more chances and much happier life in the world.
There are some effective ways to keep us healthy. Firstly, we have to form a good habit in our daily life. Franklin once said that early to bed and early to rise made one healthy and wealthy. That is to say, a good habit of life is very important for us to be successful in our career. Besides, drinking and smoking do great harm to our health, so you have to keep away from them. Secondly, exercises may keep us very strong. Although each of us is very busy with our daily work and study, we will never forget to spend some time doing exercises. Thirdly, a balanced diet is a must to keep us healthy. We’d better not have too much fat and sugar, which may cause us to become overweight. Vegetables and fruits provide us various vitamins; therefore, do not hesitate to enjoy these foods.
In conclusion, health is very valuable for each of us. If you could follow the advice we’ve proposed above, you will be sure to keep fit and enjoy your happy life.

最近，一些地方大学开始将方言列为某些学生的必修课程，学生们要学习当地方言，然后被评分以作为毕业的依据之一。一方面，支持此种做法的人认为，将方言列为必修课可防止其消失，从而使当地传统文化和文化多样性得以弘扬，同时城市独特的个性得以保留。另一方面，反对此种做法的人争论说，当地学生与外地学生相比有很多绝对优势，因此将方言列为必修课会引起教育不公平的问题。而且，将方言列为必修课程还会引起一些其他问题，如教材使用、师资问题和考试标准等。在我看来，方言作为传统文化不可缺少的一部分和一种交流工具，可以让学生自愿学习和使用，而不是强制完成。
答案：
Recently, it has been practiced by some local universities that dialect is made a compulsory course for some students, under which students are subject to learning the local dialect and then graded as one of the judging factors for them to graduate. On the one hand, people approving the practice maintain that it will help to prevent the dialect from extinguishing so that the local traditional culture and the cultural diversity can be enhanced, and the unique urban identity can be preserved simultaneously. On the other hand, people in opposition to the practice contend that it will give rise to the appearance of educational inequality, for the local students will enjoy absolute advantages over those from other places. Moreover, the inclusion of dialect in compulsory courses will bring forth other problems like teaching material, teachers and examination standards. As far as I am concerned, dialects, as an indispensable part of local traditional culture as well as a tool for communication, can be acquired and used voluntarily, not compulsorily.

1、【题目】Without regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging.
Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secret chemical agents that are conveyed by the bloodstream and regulate distant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participation of the nervous system.
The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. The term “endocrine” was introduced shortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.
1.What is the author’s main purpose in the passage?
A.To explain the specific functions of various hormones.
B.To provide general information about hormones.
C.To explain how the term “hormone” evolved.
D.To report on experiments in endocrinology.
2.The passage supports which of the following conclusions?
A.The human body requires large amounts of most hormones.
B.Synthetic hormones can replace a person’s natural supply of hormones if necessary.
C.The quantity of hormones produced and their effects on the body are related to a person’s age.
D.The short child of tall parents very likely had a hormone deficiency early in life.
3.It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed that chemical integration occurred only___.
A.during sleep.
B.in the endocrine glands.
C.under control of the nervous system.
D.during strenuous exercise.
4.The word “liberate” could best be replaced by which of the following?
A.Emancipate B.Discharge C.Surrender D.Save
5.According to the passage another term for exocrine glands is___.
A.duct glands
B.endocrine glands
C.ductless glands
D.intestinal glands.

1、【题目】We can begin our discussion of “population as global issue” with what most persons mean when they discuss “the population problem”: too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to “a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes.”
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world’s population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.
1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?
A.A virtually stable or slightly decreasing period and then a sudden explosion of population.
B.A slow growth for a long time and then a period of rapid, dramatic increase.
C.Too many people on earth and a few rapid increase in the number added each year.
D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lower mortality.
2.During the first period of demographic history, societies were often in danger of extinction because___.
A.only one in ten persons could live past 40.
B.there was higher mortality than fertility in most places.
C.it was too dangerous to have babies due to the poor conditions.
D.our ancestors had little enthusiasm for more children.
3.Which statement is true about population increase?
A.There might be an increase of 2.2 billion persons from now to the year 2000.
B.About 50,000 babies are born every six hours at present.
C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.
D.The population increased faster between 8000BC and 1650 than between 1650 and the present.
4.The author of the passage intends to___.
A.warn people against the population explosion in the near future.
B.compare the demographic growth pattern in the past with that after 1650.
C.find out the cause for rapid increase in population in recent years.
D.present us a clear and complete picture of the demographic growth.
5.The word “demographic” in the first paragraph means___.
A.statistics of human.
B.surroundings study.
C.accumulation of human.
D.development of human.
