20年前，村里未了一位疯女人。父亲因家穷，35岁一直未娶媳妇，奶奶就收下疯女人给我父亲做了媳妇。娘生下了我，但因娘疯，我一生下来，奶奶就一直不让娘靠近我，我也从来不喊娘，我们之间的交流是以我“吼”为主。娘却从来不计较，总是以那原始的特有的母爱培我送饭送菜。在我上高中的时候，娘赶了几十里路，带着邻居婶婶帮忙炒的成莱和十几个野鲜桃来看我。因为我说了句“这桃挺甜的”，娘为了再摘到鲜桃，竟从几十米的峭壁上掉下去掉死了。当我看到娘的尸体时，悲痛得五脏俱裂，紧紧地抱住娘，说：“娘啊，我苦命的娘啊，几悔不该说那桃子甜啊，是儿子要了您命……”

The number of speakers of English in Shakespeare’s time is estimated 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 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.

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.
