It is clear in cities in the world .The first city with more than a million people was Rome in 133 BC. However, in the 20th century very big cities with populations of millions became common worldwide.There are two main reasons why people move to cities: to find either a better job or a life with better quality. In 1950 only 30% of the world's population lived in cities, while in the year 2000 about half of the people throughout the world lived in cities.The growth of the population in cities has created a number of problems. Houses get smaller and buildings get taller. There are fewer parks and open areas and more cars. Overcrowded cities often have to deal with several serious problems, such as unemployment(失业), traffic, pollution and crime.In developing countries the situation is even worse. A large number of people can't afford a house or a flat, so they live in huts.By looking at the table below one can see that the problems will get worse in the future. Therefore, it is important for these countries to improve the quality of life in these cities in the future.21. Why do people move to cities according to the passage?A. Because there are many tall buildings in cities.B. Because cities can help people improve the quality of jobs.C. Because cities will have smaller population and less crime.D. Because people want to find better jobs and improve the quality of life.22. In the year 2000, about ________ of the world's population lived in cities.A. 15%B. 30%C. 50%D. 60%23. Many people live in huts, for the fees for houses and flats are ________.A. lowB. impossibleC. unknownD. high24. From the table, we know the population of ________ is the largest.A. TokyoB. New YorkC. Mexico CityD. Shanghai25. Which of the following is TRUE according to the passage?A. In developing countries most people live in flats in town.B. A large number of big cities were created in the 20th century.C. The population of cities in developing countries will stop growing.D. Helping people get jobs is very important in developing country.四、短文填空(每小题1. 5分, 共15分)选择合适的词并用其适当形式完成短文。

It is a population control method （控制方法）.The Chinese government aimed（打算）to control the increasing population at that time. Many Chinese couples understood that and followed this policy for nearly 40 years. Everyone should be responsible for our country.However, as time goes by, some problems appear in our society. At present, these problems are mainly about:●The number of workers changed from about 960 million in 2023 to 940 million in 2023. The number changed to 930 million in 2023 and fell by29 million by 2023.●China is now getting into an aging society. There will be more old people in the following years. But the society will be short of doctors and nurses to take care of them.●The population of China will become smaller and smaller if the one-child policy continues（持续）.It's the basic reason that leads to the two problems above.That's why the Chinese government began the second-child policy on January 1st, 2023. It allows each family to have a second child. The government expects it can help solve those social problems gradually（逐渐地）.This policy will help offer enough workers in the future and prevent our country from entering the aging society. It is reported that there will be around 2.5 million newly-born babies each year.11.From the passage, we know that ______.A. our government is facing 3 main problemsB. the one-child policy started on January 1st, 2023C. our population increased a lot from 2023 to 2023D. the second-child policy won't work at all12.The underlined word "that" in Paragraph 2 means ______.A. the familyB. the increasing populationC. the one-child policyD. the second-child policy13.The number of workers was ______ in 2023.A. 960 millionB. 940 millionC. 930 millionD. 29 million14.You may read this passage in the ______ part in a magazine.A. Travelling and TransportationB. Society and HistoryC. Food and HealthD. Science and Art15.The writer thinks it is ______ to announce（宣布）the second-child policy.A. impossibleB. uselessC. meaninglessD. necessaryBThe world itself is becoming much smaller by using modern traffic and modern communication means（工具）.Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it. Man has been polluting the earth. The more people there are, the more pollution there is. Many years ago, the problem was not so seriousbecause there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.Man is now slowly polluting the whole world.Air pollution is still the most serious. It's bad for all living things in the world,but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by sulfur dioxide （SO2）is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution. The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must pay attention to the rise in pollution at the same time.16.According to the passage,_____, our world isbecoming much smaller.A. because of the rise in pollutionB. thanks to the science developmentC. because the earth is being polluted day and nightD. because the earth is blown away by the wind every year17.Hundreds of years ago, life was ____ it is today.A. as easy asB. much easier thanC.as hard asD. much harder than18.In Paragraph 1, the underlined word " it" means ____.A. rubbishB. noise pollutionC. air pollutionD. water pollution19.Which of the following is NOT trueA. Many countries are making rules to fight pollution.B. The pollution of the earth grows as fast as the world population does.C. The problem of the pollution is not so serious because there are not so many people living on the earth.D. If people could go to work by bus or by bike instead of by car or by motorbike, it would be helpful in fighting against the problem of SO2.三、补全对话A.Do you know what the worlds population is todayB.I’m reading a book about the world's population these days.C.I think we must do something to control the population.D.It’s too bad.E.It was no more than 2 billion.A : What are you up toB:① _______A:Sounds good! What’s it aboutB:It says that 1,000 years ago ,the world’s population was very small.②_____A : ReallyB:Yes, but during the last three or four hundred years, the world’s population has grown very quickly. Today ,it is growing faster than ever.③______A:Sorry, I don't know.B: It’s more than 7 billion.A: It’s so large. ④_______B:Yes.
