Climate change, pollution, overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze, India’s Ganges and Africa’s Nile, WWF said on Tuesday．At the global launch of its report “World’s Top 10 Rivers at Risk”, the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic life．

 “If these rivers die, millions will lose their livelihoods, biodiversity will be destroyed on a massive scale, there will be less fresh water and agriculture, resulting in less food security,” said Rayi Singh, secretary-general of WWF-India．The report launched ahead of “World Water Day” today, also cited the Rio Grande in the United States, the Mekong and Indus in Asia, Europe’s Danube, La Plata in South America and Australia’s Murray-Darling as in need of greater protection．

Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up．Dams have destroyed habitats and cut rivers off from their flood plains while climate change could affect the seasonal water flows that feed them, the report said．Fish populations, the top source of protein and overall life support for hundreds of thousands of communities worldwide, are also being threatened, it found… The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization, damming and huge influxes of sediment from land conversion．

Climate change, including higher temperatures, also means serious consequences for fishery productivity, water supply and political security in Africa’s arid Nile basin．Tributaries flowing into the Ganges are drying up because of irrigation, WWF said．

What does the text mainly talk about?

      A．Saving fresh water in our life．             B．How to protect our rivers．

      C．An important discovery．                  D．World’s top 10 rivers are at risk．

We can infer from the text that _____．

      A．rivers’ dying out could affect food security  

       B．there are four Asian rivers mentioned in the passage  

       C．the Yangtze is polluted thanks to the lack of enough tributaries 

       D．higher temperatures couldn’t affect fishery productivity

The top 10 rivers are fast dying as a result of the following EXCEPT _____．

      A．climate change    B．wasting water   

       C．pollution              D．dams

WWF is probably a name of _____．

      A．a(chǎn)n organization      B．a(chǎn) newspaper         C．a(chǎn) magazine           D．a(chǎn) report

XI'AN - China's conservation work for the endangered crested ibis（朱鹮）is facing new challenges, including an increasing mortality rate due to inbreeding, and the conflict between the need to expand natural habitats and local communities' economic interests, bird experts have warned.
The crested ibis, once widespread in Japan, China, Russia and the Korean Peninsula, almost became extinct in the first half of the 20th century.
Before 1981, when seven crested ibis were accidentally found in Yangxian county, in Northwest China's Shaanxi province, academics thought the species had been extinct in China for almost 17 years.
Due to the huge effort put into species protection since 1981, the number of crested ibis in China has risen to an estimated 1,617, including 997 in the wild, the State Forestry Administration said at a meeting on crested ibis protection in Xi'an on Monday.
However, although the ibis population exceeds 1,000, the birds are still not free from the threat of extinction, said Fang Shengguo, director of the State Conservation Center for Gene Resources of Endangered Wildlife at Zhejiang University.
“Ornithologists used inbreeding in the early stages of protection so that numbers of the precious birds could increase quickly, but that method had consequences,” Fang said.
"Studies have proved that as a result of inbreeding, crested ibis have the lowest genetic diversity of all endangered birds," Fang said.
"It means a high mortality rate and more physical defects for hatched chicks."
“The government should collect genetic information from all crested ibis and establish a genetic database as soon as possible, then design a scientific mating plan for the species,” Fang said.
So far, about 90 percent of crested ibis live in Shaanxi province, and fewer than 140 ibis live in three zoos in other parts of the country, including Beijing Zoo, according to Liu Dongping, an assistant researcher at the National Bird Banding Center of China, which is affiliated to the Chinese Academy of Forestry.
The bird has lost the ability to migrate, he said, adding that if an unexpected natural disaster occurred in Shaanxi province or an infectious disease spread through the area, the ibis population could be greatly reduced.
Experts also warned that the increased population of ibis, whether in the wild or in captivity, requires a larger and more varied natural habitat.
Rampant hunting, the massive loss of habitat caused by deforestation and the overuse of pesticides, which killed aquatic insects on which the ibis feed, are believed to be the main reasons for the sharp reduction in the ibis population before 1981.
So, in 1983, a State-level natural reserve was set up in Shaanxi province to protect the bird. But the struggle for living space between human and animal has never stopped, said Lu Baozhong, deputy director of the Shaanxi Crested Ibis Conservation Station.
"For example, ibis often look for loaches in farmers' rice fields. Sometimes their claws trample the rice seedlings. In another case, villagers discovered some land with abundant mineral resources which happened to be a habitat for ibis," said Lu, who has devoted 30 years to ibis protection.
A long-term win-win solution for ibis and local communities needs to be developed, one that would provide ecological compensation for local residents, Lu said.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.
Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.
The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr.Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on -one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says.
If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use. Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.
【小題1】From the first two paragraphs, we can know                   ．

A．cell phones have become as addictive as cigarettes
B．cell phone addiction is good for building personal relationships
C．people are longing to have their own cell phones
D．cell phones are the same as cigarettes
【小題2】Cell phone addiction has caused the following effects EXCEPT            .
A．a(chǎn) barrier to personal contactB．fewer friends
C．a(chǎn)n escape from realityD．a(chǎn) serious illness
【小題3】The underlined word "curb" in Paragraph 2 means “           ．”
A．ignoreB．controlC．developD．rescue
【小題4】The example of a woman talking on the phone in the car supports the idea that        .
A．women Use cell phones more often than men
B．talking on the phone while driving is dangerous
C．cell phones do not necessarily bring people together
D．cell phones make one - on - one personal contact easy
【小題5】Which of the following is the best title for the passage?
A．Cell phones Are the New Cigarettes
B．Cell phones Are Harmful to the Society
C．The New Report about the Cell phone
