Australia is the world's smallest continent and largest island, a relatively young nation established in an ancient land. Its development represents a triumph(胜利)over remoteness and a harsh landscape.
It is generally accepted that Australia's original inhabitants, the aboriginal(土著的)people, have lived on the continent for 40,000 to 60,000 years. They were also its sole(唯一的)human inhabitants until two centuries ago. Indonesian traders probably visited Australia's northwest but it was unknown to the rest of the world until the 1600s. A huge south land appeared on maps before 200 AD but its existence was not confirmed until the 17th century when Portuguese, Spanish and Dutch merchants ventured into Asia.
The first European settlement of the continent--by the British--began in 1788, on the site now occupied by Sydney, Australia's largest city. There were then about 1500 Europeans and an estimated 300,000 aboriginal people in Australia. The population has reached 2.25 million by 1881, 5.41 million by 1921 and 7.4 million by the end of World War II(1945). It increased sharply, partly because of a large postwar immigration program, and reached more than 17 million in 1991, despite a decline that began in the 1970s in the natural increase and net immigration. The rate of population increase in the 40 years after world war II, about two percent, has halved.
Australia is one of the most urbanized countries in the world, with about 70 percent of the population living in the 10 largest cities. Australians have a high standard of living by world standards. The flag of Australia is the only one to fly over a whole continent in the world. The small Union Jack represents the historical link with Britain, the largest star has six points for each of the states and one point for the territories, and the small stars form. the Southern Cross - a prominent of the southern hemisphere night sky.

未分类题The journey two divers(潜水员)made some time ago to the very deepest point on the earth make us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small ball to find out if there are any ocean currents(水流)or signs of life.It was necessary to set out early, so that the ball would come to the surface in daylight, and so be easily found by the mother ship which would be waiting for it. The divers began preparations(准备)early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.The divers felt as if they were going down steps as they passed through warm and cold layers(层)of water. In time, the temperature dropped to freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth(深度)of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking(爆裂)noise: even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer(外部的)windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of 'dust' made up of small dead sea-creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure(压力). But they did not dare to leave the lights on for long , as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint(微弱的)but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none the worse for their experience.1. The purpose of the diver's journey to the deepest point on the earth was to find _____.A. if there are water currents and life in the great depthsB. if people can stand the severe cold in the great depthsC. if there are steps in the great depthsD. if the telephone works well in the great depths2. The divers set out early in the morning so that _____.A. they could return to the surface during the dayB. they could see at the bottom of the oceanC. they could avoid the cold at nightD. they could stay long at the bottom3. Which of the following statements is true?A. The ocean water temperature decreases steadily with the depthB. There are steps on the way to the bottom of the Pacific OceanC. There are steps between the water layers of different temperatureD. The water layers of different temperatures made the divers feel as if they were going down steps4. As the divers went down to the ocean floor, the telephone _____.A. kept working all the timeB. stopped working at a depth of 3,000 feet and began working again after they reached the bottomC. stopped working at a depth of 3,000 feet and began working at 30,000 feetD. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth5. On the ocean floor, the divers found that _____.A. there was no life but some small dead sea-creaturesB. fish were swimming as freely as they do near the surfaceC. fish were not swimming freely in the dark waterD. fish were not swimming freely under the high water pressure

未分类题Tim Berners-Lee is the man who wrote the software(软件)programme that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners-Lee both worked on one of the earliest commercial(商业的)computers and talked about their work at home. As a child he would build models of computers from packaging material. After graduating from Oxford University he went on to the real thing. In the 1980s scientists were already communicating using a primitive version(原始版本)of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a programme, which let him store these messages. This gave him another idea: write a programme that will let academics(学术界人士)from across the world share information on a single place. In 1990 he wrote the HTTP(服务程序所用的协议)and HTML(超文本链接标示语言)programmes which form. the basis of the World Wide Web.The next year his programmes were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used his codes(编码)to work with different operating systems. New things like web browsers(浏览器)and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000.In 1994 Tim Berners-Lee formed the newly formed World Wide Web Consortium(协会)，or W3C. More than 200 leading companies and laboratories are represented(代表)by W3C. Together they make sure that everyone can share equally on the web. 'The Web can help people understand the way that others live and love and are human. It helps us understand the humanity of people, 'he says.1. From the lines we can infer that Tim Berners-Lee is _____.A. BritishB. AmericanC. SwissD. French2.

未分类题A greenhouse is a building made of glass which is used for keeping plants when the outside temperature is low. In a similar way there are several gases in the atmosphere which trap(捕捉)the heat produced by the sun and prevent it from escaping. These gases are known as'greenhouse gases'，and the way in which they trap heat in the atmosphere is called the 'greenhouse effect'. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forests. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide(二氧化碳)in the atmosphere doubles, there will probably be a rise in the earth's temperature of between 1 and 4 degrees. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.1. The'greenhouse effect'means _____.A. the way in which gases are used for keeping plants warmB. a natural course which is some degree helpful to usC. the way'greenhouse gases'trap heat on the earthD. the whole course in which greenhouse gases prevent heat2. If there were no greenhouse effect, _____.A. no plants would grow on our planetB. earth would be thirty degrees colderC. man could not live on the earthD. All of the above answers are correct3. Which of the following is NOT true? _____A. Burning too much coal and oil produces lots of greenhouse gases.B. It has become warmer on the earth now than in the past.C. Gases put into the atmosphere now will affect the earth years later.D. The temperature in a greenhouse is as high as that in the atmosphere.4. Suppose the earth's temperature rose by 3 degrees, _____.A. great harm would be done to mankindB. the sea level would go by 10 centimetresC. all the land in the world would be floodedD. crops would be unable to grow on the earth5. This passage mainly deals with _____.A. the concept(概念)and harm of greenhouse effectB. the relation between greenhouse gases and manC. the concept and change of greenhouse effectD. the effect of the rise of the earth's temperature

未分类题Maybe ten-year-old Elizabeth put it when she said to father, 'But, Dad, you can't be healthy if you're dead.'Dad，in a hurry to get home before dark so he could go for a run，had forgotten to wear his safety belt - a mistake 75% of the US population make every day.The big question is why.There have been many myths about safety belts ever since their first appearance in cars forty years ago. The following are three of the most common.Myth Number One：It's best to be 'thrown clear' of a serious accident.Truth：Sorry, but any accident serious enough to'throw you clear'is also going to be serious enough to give you a very bad landing. And chances are you'll have travelled through a windshield(挡风玻璃)or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are 'thrown clear'.Myth Number Two：Safety belts 'trap' people in cars that are burning or sinking in water.Truth：Sorry again, but studies show that people knocked unconscious(昏迷)due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations, not to be trapped in them.Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour(mph).Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.1. Why did Elizabeth say to her father, 'But, Dad, you can't be healthy if you're dead'? _____A. He was driving at great speed.B. He was running across the street.C. He didn't have his safety belt on.D. He didn't take his medicine on time.2. The reason Elizabeth's father was in a hurry to get home was that he _____.A. wasn't feeling very wellB. hated to drive in the darkC. wanted to take some exerciseD. didn't want to be caught by the police3. According to the text, to be 'thrown clear' of a serious accident is very dangerous because you _____.A. may be knocked down by other carsB. may get seriously hurt going thrown out of the carC. may find it impossible to get away from the seatD. may get caught in the car door4. Some people prefer to drive without wearing a safety belt because they believe _____.A. the belt prevents them from escaping in an accidentB. they will be unable to think clearly in an accidentC. they will be caught when help comesD. cars catch fire easily5. What is the advice given in the text? _____A. Never drive faster than 30 miles an hour.B. Try your best to save yourself in a car accident.C. Never forget to wear the safety belt while driving.D. Drive slowly while you're not wearing a safety belt.
