People all over the world today are beginning to hear and learn more and more about the problem of pullution. Pollution is caused either by man’s release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance, such 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 can’t 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 everyone can help to solve by cutting out unnecessary buying, excess use and careless disposal of the products we use in our daily lives.
26. The main cause of pollution is __________.
A. the release of artificial or natural substances into the environment B. the production of new industrial goods C. increased amounts of a natural substance
D. our ever-increasing population
27. Much of the pollution could be controlled if only ________. A. people would pay more attention to the problem B. governments would take effective measures C. all sides concerned would make more efforts D. farmers would use less artificial fertilizers
28. Food packages, bottles and tins for drinks can cause ____________. A. air and water pollution
B. both a litter problem and a waste of resources C. to pay for the service D. to produce the receipt
29. Which of the following can not help solving the problem of pollution? A. Cutting out unnecessary buying B. Eating
C. Reduce excess use
D. Carefully dispose our daily products
30. What does the underlined word ‘ litter” mean in paragraph 2? A. not many B. serious problem C. bits of waste things D. industrial pollution 短文理解2
Benjamin Disraeli, the famous nineteenth century prime minister, said, “London is not a city, it it a nation.” Today this is an understatement; London, 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 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 London.
