Benjamin Disraeli, the famous nineteenth century prime minister, said, "London is not a city, - it is a nation." Today this is an understatementLondon, with its vast range of different ethnic groups, is a world. Certainly, London is the most culturally diverse city in the world. The city was founded by the Romans and since then new arrivals have constantly added to its character and prosperity. Within 10 years 40% of Londoners will be from ethnic minority groups, including the growing number of Londoners of mixed ethnic origin, but most of them will have been born in Britain. Children of Caribbean-Chinese marriages will go to school with children of Russian-Irish couples. None of them will be English but all of them will be Londoners. Most of Britain's ethnic minority residents live in the capital, speaking over 300 languages. Nearly all of the African population and many of the Caribbean population of Britain live in London (83% and 58% respectively)39% of the Chinese population of Britain and 36% of the Asian population of Britain live in London. The largest migrant community is from the Irish Republic with 256,000 people, 3.8% of the total population of London. There are an estimated 330,000 refugees and asylum seekers living in London, with most recent arrivals coming from Eastern Europe, North Africa and Kurdistan. Young people, in particular, are skilled at dealing with a large number of different and hybrid cultures. They themselves often have several different ethnic identities since their parents and grandparents may come from several different backgrounds and their friends and partners do also. They are "skilled cross-cultural travelers" without leaving their home-town.1.Why does the writer think that Benjamin Disraeli's statement is an understatement? Because he thinks London is ().2.

完形填空Many of the world’s pollution problems have been caused by the crowding of large groups of people into cities.Satisfying the 21 of the people leads to further polluting by industry.If the rapid increase in human population 22 at the present rate (比率), there may be much greater harm.Some scientists speak of the 23 in number of people as “Population Pollution”.About 2000 years ago, the world 24 was probably about 250 million.It reached a billion in 1850.By 1930 the population was two billion.It is 25 three and a half billion.It is expected to double by the year 2000.If the population continues to grow at the same 26 , there would be 25 billion people in the world a hundred years from now.Man has been using the earth’s 27 more and more rapidly over the years.Some of them are almost gone.Now many people believe that man’s greatest 28 is how to control the growth of this population.The materials in the world will not support the human population in time to come if the present rate of increase continues.29 there is over crowding in the cities and hunger in some countries.Can man’s rate of increase continue?Many people believe that human survival (幸存者) in the future 30 on the answer to the question.21.A.needsB.suppliesC.serviceD.supports22.A.stopsB.continuesC.slows downD.adds to23.A.increaseB.reduceC.countryD.improvement24.A.peopleB.situationC.populationD.land25.A.nowB.in the pastC.in the futureD.then26.A.placeB.timeC.rateD.result27.A coalB.oilC.minesD.resources28.A.problemB.powerC.planD.idea29.A.AlreadyB.YetC.StillD.Often30.A.feedsB.livesC.keepsD.depends

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
