What is the 'biggest city in the world? That is, (21) city has the largest population? This seems like (22) question to answer, but actually it isn't.It's actually rather difficult to say which cities (23) the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large (24) area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.The second reason that it is difficult to 25 the population of different cities is this: it is almost impossible to get (26) about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an (27) of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for (28) different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.So we can say that these are our two (29) for comparing the populations of cities: one, it's difficult to determine the (30) of a city, and two, it is difficult to get accurate information.21. A. whatB. whichC. whereD. how

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.

The world’s population continues to grow. There now are about 4 billion of us on earth. That could reach 6 billion by the end of the century and 11 billion in a further 75 years. Experts have long been concerned about such a growth. Where will we find the food, water, jobs, houses, school and health care for all these people?A major new study shows that the situation may be changing. A large and rapid drop in the world’s birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from home instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population grow.China is one of the nations that have made great progress in reducing its population growth. China has already cut its rate of population growth by about half since 1970.Each Chinese family is now urged to have no more than one child. And the hope is to reach a zero population growth with the total number of births equaling the total number of deaths by the year 2000.Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.1. The world’s population could reach ____________.A. 6 billion in 75 yearsB. 11 billion in 2075C. 11 billion by the end of this centuryD. 600 million in 15 years2. Which of the following is true?A. The world’s birth rate is higher than ten years ago.B. There has been a slower population growth in the past ten years.C. Families are as large as before.D. Birth control has been well practiced in all nations.3. By the year 2000, the number of births and the number of deaths in China will _______.A. be greatly differentB. drop a great dealC. be equalD. become much larger4. According to the essay, China’s population control ________.A. is not quite successfulB. should be considered a big successC. is far from being successfulD. is a complete failure5. It may happen in the future that the people who are working in Europe will have to pay much higher taxes because___________.A. more and more children will be bornB. the number of retired people will become ever largerC. fewer and fewer children will be bornD. they will be making a lot of money

New Foods and the New WorldIn the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with. According to the passage,which of the following has changed the most in the last 500 years?A: Food.B: Chocolate.C:Potato.D: Coffee.
