【简答题】
The number of speakers of English in Shakespeare’s time is estimated(估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms. In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation. The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West. 小题1:What would be the best title for this passage? A.The Difficulties of Learning English B.International Communications C.The Standard Varieties of English D.English as a World Language 小题2:Which of the following statements is NOT true? A.Some 260 million people in the world have an adequate working knowledge of English. B.There are some 260 million native speakers of English in the world. C.It is almost impossible to estimate the number of people with an adequate working knowledge of English. D.People learn English for a variety of reasons. 小题3:According to the passage, what is the main reason for the widespread use of English? A.It was popular during Shakespeare’s time. B.It is used in former British colonies. C.It serves the needs of its native speakers. D.It is a world language that is used for international communication. 小题4:What forms an adequate working knowledge of English? A.The ability to read a newspaper. B.It is difficult to judge because it differs for each situation. C.Being a multilingual. D.Being a native speaker. 小题5:What type of developing countries would be most likely to use English? A.Those geographically close to the United States. B.Those interested in the culture of the United States. C.Former colonies of Great Britain. D.Countries where international conferences are held.
