[单项选择]Half the world’’s population will be speaking or learning English by 2015, researchers say. Two billion people are expected to start learning English within a decade and three billion will speak it,says a British Council estimate.
Other languages, such as French, risk becoming the casualties of this "linguistic globalization". But the boom will be over by 2050 and the English-language teaching industry will have become a victim of its own success, says David Graddol, author of the report, The Future of English.
Mr. Graddol’’s research was based on a computer model developed to estimate demand for English-language teaching around the world. The lecturer, who has worked in education and language studies at the Open University for the past 25 years, said the model charted likely student numbers through to 2050.
It was compiled by looking at various estimates from the United Nations Education, Scientific and Cultural Organization (Unesco) on education provision, demographic projec

[简答题]Concern for family values is reducing among younger Japanese as they pursue an inner world of private satisfaction. Data collected by the Japanese government in 1993 show that only 23% of Japanese youth are thinking about supporting their aged parents, in contrast to 63% of young Americans. It appears that many younger-generation Japanese are losing both respect for their parents and a sense of responsibility to the family. Experts attribute the change to Japanese parents’ over-spoiling of their children, material plentifulness, and growing concern for private matters. The shift toward individualism among Japanese is most striking among the very young. According to data provided in 1991, 50% of Japanese youth aged 16 to 19 can be labeled "self-centered", compared with 33% among those aged 25 to 29. To earn the label, the young people responded positively to such ideas as "I would like to make decisions without considering traditional values" and "I don’t want to do anything I can’t enj

[单项选择]The fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: "store in the refrigerator."
In my fridgeless fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.
The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed--natural cooling, drying, smoking, salting, sugaring, bottling...
