In the early 15th century, the British took over the continent of Australia and declared it “terra nullius”.() 此题为判断题(对，错)。
The continent of Australia is the largest, fattest and driest continent in the world.() 此题为判断题(对，错)。
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.1. The passage is written to _____.A. present a general picture of AustraliaB. persuade people to travel in AustraliaC. tell people the history of AustraliaD. describe the characteristic of Australia2. The first sentence in paragraph 1 mainly suggests that _____.A. Australia is a strange countryB. it is not easy to find AustraliaC. Australia has contradictory(矛盾的)featuresD. Australia is a continent and a country as well3. Which statement about Australia's population can NOT be inferred? _____A. The population change is a gradual increase.B. The population increased rapidly for a time owing to the government's special policy.C. The rates of population increase in different periods varied.D. The rate of population increase before World War II was about one percent.4. The word urbanized means _____.A. of towns or citiesB. of emergencyC. of suburbsD. of the countryside5. Which of the following statements is NOT true? _____A. The large star on the flag of Australia has seven points.B. People were certain of Australia's existence before 200 AD because it had appeared on maps.C. Australia enjoy relatively high standard of living compared with people in other countries.D. The aboriginal people of Australia were its only human inhabitants before the 18th century.

But the explorers can stay alive.What about animals?Can they survive?Do we find plants?Do we find life in the Arctic and in Antarctica?Yes,we do.There is life in the oceans.There is life on land.Antarctica,as we have seen,is a cold place indeed.But this has not always been the case. Expedition scientists have discovered that Antarctica has not always been a frozen continent.

共用题干Touring the Antarctic Brings Danger1 Ship tourism to Antarctica is on the rise.More than 35,000 tourists are expected to visit Antarctica this spring and summer. In 1992一1993,6,750 visited Antarctica,according to the Antarctic Treaty Secretariat. All of this tourism,however,is posing great danger to both tourists and the environment.2 Among the tourist ships that visit the continent,the Explorer,a Canadian ship,was one of the first. Launched in 1969,it was built to ferry tourists to Antarctica.Last week,however,it became the first commer- cial passenger ship to sink beneath the polar region's waters.Fortunately,all of the passengers and crew members were evacuated（撤离）from the ship. However , the sunken ship threatens the Antarctic'S fragile environment.The ship was estimated to be holding 48,000 gallons of marine diesel fuel.3 The accident was not unanticipated.Both the US and the UK had warned at a conference of Antarc- tic treaty nations in May that the tourism situation in the region was a potential disaster. The US said in a pa- per,"People should take a hard look at tourism issues now,especially those related to vessel safety.""The increasing number of ships operating in Antarctica means that ships are under greater pressures to meet the time slots for visiting key sites,"the British government wrote in a paper at the meeting of treaty nations.4 Although the Antarctic seas are relatively calm,floating ice poses a potential threat to ships.The owner of the Explorer attributed the sinking to a fist-size hole in the hull created by ice.Many of the other large cruise ships now visiting Antarctica have little or no ice reinforcement in their designs.Such ships generally can only come to the continent at the height of summer. But the tourist rush is pushing vessels into dangerous situations.5 As a natural frontier,Antarctica is in a legal muddle.There are no obvious answers as to who is re- sponsible for dealing with the threat that tourism may cause to human life and the environment.6 Jim Barnes,executive director of the Antarctic and Southern Ocean Coalition,told the New York Times,"There'S no military or coast guard for Antarctica."He asked,"Do we want this(the Antarctic)to become Disneyland,or do we want some controls?"The accident of the Explorer's sinking is__________.A:safeB:being hit by floating iceC:pollute the seaD:foreseenE:unclearF:dealing with the threat

问答题Practice 10 Glaciers in Antarctica are melting faster and across a much wider area than previously thought, a development that threatens to raise sea levels worldwide and force millions of people to flee low-lying areas. Researchers once believed that the melting was limited to the Antarctic Peninsula, a narrow tongue of land pointing toward South America. But satellite data and automated weather stations now indicate it is more widespread. The melting also extends all the way down to what is called west Antarctica. By the end of the century, the accelerated melting could cause sea levels to climb by 3 to 5 feet-levels substantially higher than predicted by a major scientific group just two years ago. Making matters worse, the ice shelves that hold the glaciers back from the sea are also weakening. For years, the continent at the bottom of the world seemed to be the only place on the planet not experiencing climate change. Previous research indicated that temperatures across much of Antarctica were staying the same or slightly cooling. The big surprise was exactly how much glaciers are melting in western Antarctica, a vast land mass on the Pacific Ocean side of the continent that is next to the South Pole and includes the Antarctic Peninsula. The glaciers are slipping into the sea faster because the floating ice shelf that would normally stop them—usually 650 t0980 feet thick—is melting. And the glaciers' discharge is making a significant contribution to increasing sea levels. Together, all the glaciers in west Antarctica are losing a total of around 114 billion tons per year because the melting is much greater than the new snowfall. That's equivalent to the current mass loss from the whole of the Greenland ice sheet, New research found that melting glaciers will add at least 7 inches to the world's sea level—and that's if carbon dioxide pollution is quickly capped and then reduced.
