Pollution is caused either by mans release of completely new and often artificial (An 0, ) substances into the environment, or by releasing greatly increased amounts of a natural substancesuch as oil from oil tankers into the sea.Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three of four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cant be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metal and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need,but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyonecan help to solve by cutting out unnecessary buying, excess use and careless disposal (处理) of the products we use in our daily lives.26.

Today this is an understatement; London, with its vast range of different ethnic groups, is aworld. 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 Car- Chinese marriages will go to school with children of Russian - Irish couples. None of them will i bbean be English, but all of them will be Londoners. Most of Britains 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 mingrant 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 diferent 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 travellers without leaving their home - town.31. Why does the writer think that Benjamin Disraelis statement is an understatement? Because he thinks London is D . A. part of the world B. even larger than some countries in the world C. not a nation at all D. a miniature world thanks to its great cultural diversity32.

London accommodates about 330,000 refugees and asylum seekers from many other countries D. many young people are immigrants from different backgrounds33.

Her father was a soldier and was sent by the governmentto India. He took all his family with him, and they lived in Calcutta, in a house which the army gave them. Joan liked living in India. She liked the food and the warm weather. As a child, she would go to school in the morning, but in the afternoon, she used to go out riding on her horse.When she was 20, the British left India and family returned to Liverpool. Joan didnt want to return with them, so she decided to get a job and stay in India. In the 1940s in India there were not many jobs that an English woman could bo, so she decided to study to become a nurse and work in a hospital there. Joan finished her studies in 1950 and started working in a large hospital caring for sick children. She was a very good nurse because she was very kind and worked very hard.When she was working at the hospital, she met a doctor named Gupta. Joan and Gupta started going to restaurants and the cinema together, and soon decided to get married. Joans family returned to India for the wedding. After two more years working in the hospital with Gupta, Joan decided that she wanted to bo more to help the sick children in the city. She knew that the hospital only helped the children whose parents could pay for the medicine the children needed. Joan decided to start a charity to help children whose parents didnt have enough money.The charity Joan started has now become the largest childrens charity in India. It has helped over 40,000 children since it was set up in 1955. It has grown and now helps children in other cities as well as Calcutta. In 1992 the charity built its own hospital in Calcutta.
