Of the 7,000 languages spoken in the world today, linguists (语言学家) say, nearly half are likely to disappear this century. In fact, one falls out of use about every two weeks.
Some languages die out in an instant, at the death of the only surviving speaker. Others are lost gradually in bilingual (双语的) cultures, as local tongues are edged out by the dominant (占主导地位的) language at school, in the marketplace and on television.
New research, supported by the National Geographic Society and the Living Tongues Institute for Endangered Languages, has found the five regions where languages are disappearing most rapidly. They are northern Australia, central South America, North America's upper Pacific coastal zone, eastern Siberia, and Oklahoma and the southwestern United States.
K. David Harrison, an associate professor of linguistics at Swarthmore College, US, said that more than half the languages had no written form and were vulnerable to loss and being forgotten." Their loss leaves no dictionary, no text, or no record of the accumulated knowledge and history of a disappeared culture.
Harrison and other researchers started their rescue project last year. They have been trying to identify and record endangered languages. They interviewed and made recordings of the few remaining speakers of a language and collected basic word lists. The individual projects, some lasting three to four years, involve hundreds of hours of recording speech, developing grammar and preparing children's readers in the obscure (逐渐没落的) language. The research has concentrated on preserving entire language families.
"These are probably languages that cannot be brought back, but at least we made records of them," said Gregory Anderson, director of the Living Tongues Institute, in Oregon, US.

Although Thomas Edison created the technologies behind three major 21st century industries electrical power，recorded music and movies—his greatest invention may have been the modern method of inventing．He basically came up with the modern system of research and development．Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds．Edison’s laboratories were the forerunners（ 先驱）of Apple，Google and Microsoft．
Yet for all his scientific gifts，he was no Steve Jobs or Bill Gates．He once said，“Anything that won’ t sell，I don’ t want to invent．” But Edison，unlike Jobs or Gates，had no real sense of what the public wanted or how to change his discoveries into products that might sell．It took him years to understand that the phonograph（ 留声机）was not a business tool but an entertainment invention．He helped create movies but resisted the idea that people might want to go into a theater to watch one．
We chose Edison this year because we need his example now more than ever．Though we live in a time of great reformation，the U．S．is in danger of losing its advantage in science and technology．American investment（ 投资）in research and development has not increased as a percentage of GDP since the mid一1980s，while the government’ s share has been dropping．And this is at a time when China is rapidly increasing its money on research and development．The U．S．was once among the leading nations．Now it ranks near the bottom of the 23 nations that collect such data．We hope that Edison’ s story might not only encourage reformation but also inspire more young Americans to study science and engineering．
1．The first paragraph is mainly about .
A．the number of Edison’ s great inventions
B．Edison’ s special personal characters
C．Edi son’ s modern system of research
D．Apple．Google and Microsoft and their forerunners
2．Which of the following is TRUE according to the passage?
A．All the things Edison invented sold well．
B．Edison wanted to invent things that sold well．
C．Edison’ s inventions were not valuable for being unpopular．
D．Edison had a gift for changing his discoveries into best sellers.
3．The author’ s main purpose is to ．
A．inform US of the danger the USA is in
B．get young Americans to study science
C．be in honor of Edison for his contributions
D．tell US how important Edison’ s inventions are
4．We can infer from the text that ．
A．the USA is no longer advanced in science and technology
B．the USA falls behind China in research and inventions
C．more and more young Americans will be interested in science
D．China is spending more and more money on research and development
Birds are the only animals with feathers, although some other animals, such as insects and bats, also have wings．Nearly all birds can fly, and even flightless birds, such as ostriches （鸵鸟）, penguins, evolved from flying ancestors．
Birds are found worldwide in many habitats．They can fly over some of the highest mountains on earth as well as both of the earth’s poles, dive through water to depths of more than 250m, and occupy habitats with the most extreme climates on the planet, including arctic tundra （冻土地带） and the Sahara Desert．Certain kinds of seabirds are commonly seen over the open ocean thousands of kilometers from the nearest land, but all birds must come ashore to raise their young．
Highly developed animals, birds are sensitive and responsive, colorful and graceful, with habits that excite interest and inquiry．People have long been fascinated by birds, in part because birds are found in the same habitats in which humans live．And like people, most species of birds are active during daylight hours．Humans find inspiration in birds’ capacity for flight and in their musical calls．Humans also find birds useful---their flesh and eggs for food, their feathers for warmth, and their companionship．Perhaps a key basis for our friendliness with birds is the similarity of our sensory worlds: Both birds and humans rely more heavily on hearing and color vision than on smell．Birds are useful indicators of the quality of the environment, because the health of bird populations mirrors the health of our environment．The rapid decline in birds populations and the accelerating extinction rates of birds in the world’s forests, grassland, wetlands, and islands are therefore reasons for great concern．
1.Which of the following would be the best title of the text?
A．Animals with Feathers and Wings
Our friendliness with birds
C．An introduction to Birds
D．Bird’s life
2.What does the second paragraph mainly tell us ?
A．Bird’s
friendship
Bird’s habitats

3.Which of following is NOT true according to the passage ?
A．Bird’s flying abilities and musical calls inspire humans greatly．
Birds live in the same surroundings in which humans live．
C．Both birds and humans rely more heavily on hearing and smell than on color vision．
D．Bird’s flesh and eggs for food, bird’s feathers for warmth, and their companionship are useful to us．
4.From the text it may imply but NOT state that __________．
A．the environment is being damaged seriously
if you want to raise birds, you should pay attention to
environment
C．the environment affects the human beings
D．bird populations decrease rapidly
The income gap between China's rural and urban residents(居民) has continued to widen during the past few years in spite of rapidly rising rural incomes, Agricultural Minister Sun Zhengcai said here on Wednesday.
The income ratio(比率) between urban and rural residents was 3.28:1 in 2006, against 3.23:1 in 2003, said Sun in his report on the promotion of building a new countryside in 2007. Sun also said the net income of rural residents in different regions also varied widely. The income gap is only one of several problems in rural areas, according to Sun's report. While listing the achievements in rural areas in recent years, Sun believed that rural development still followed behind urban development.
"We have bigger pressure to ensure the supply of major agricultural products such as grain," he said. "China's urbanization(都市化) has been speeded up and more rural residents have gone to urban areas," he said.
"In this case, more agricultural producers become farm produce consumers, which created more pressure for supply," he said.
Another problem facing China's agricultural development is inadequate application of science and technology.
"Only 30 percent of scient ific and technological achievements have been applied to agricultural production, which is 40 percentage points lower than developed countries," he said.
Despite increased government spending in rural areas, the infrastructure(基础下部组织) is still poor and easily hit by disasters.
According to Sun, the government spent 431.8 billion yuan ($59.15 billion) on agriculture, rural areas and farmers this year, an increase of 80.1 billion yuan over the previous year.
China set aside 11.38 billion yuan to promote a new rural cooperative medical care system and 27.98 billion yuan to support the new compulsory education mechanism in rural area to ensure that all citizens shared the fruits of China's reform and opening-up, Sun said.
68．Which of the following is TRUE according to the text?
A．Because of the rapidly rising rural incomes, the income gap between China's rural and urban residents will disappear this year.
B．The net income of rural residents in different regions is the same.
C．The government has taken measures to develop the economy in the rural areas.
D．Beca use of the rapidly rising rural incomes, the supply of major agricultural products is enough.
69．Can you infer the meaning of the underlined words in paragraph 5?
A．be made full use of B．be made little use of
C．be not made full use of D．be made good use of
70． How much is spent on agriculture, rural areas and farmers the previous year?
A．431.8 billion yuan B．511.9 billion yuan
C．351.7 billion yuan D．80.1 billion yuan
71． Which is NOT the problem in rural areas?
A．The income gap
B．The inadequate application of science and technology
C．The supply of major agricultural products
D．China's urbanization
