Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.

Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.

“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.

The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.

“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近亲交配) problems ... and at the end these species may disappear,” he added.

Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.

The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.

Other consequences could include the spread of invasive species and infectious diseases, it said.

The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(红树林), inland waters, forests, savannahs(非洲大草原) and grasslands.

The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.

The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.

It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.

The South China tiger could become extinct within 30 to 50 years if it does not receive protection. There are only 20 to 30 South China tigers in their earliest natural places, with Guangdong Province having only five left because forests are being destroyed as a result of rapid industrial growth.

The South China tiger can live 20 to 25 years, but the survival rate for the young is becoming lower as a result of rapid growth in industry and tourism. Even with hard work, it is hoped that the number of South China tigers can only reach 150 to 180 in the coming century.

68. The underlined word “extinct ” means ______.

  A. different       B. seriously ill      C. no longer exist     D. frightening

69. The best title for this news could be ______.

  A. The Life Span of the South China Tiger   

B. The Coming Century for the South China Tiger

C. Chinese Scientists Call SOS for South China Tigers

D. Industrial Growth—The Enemy of South China Tiger

A German company was concerned about talks in Moscow trying to sell some 100 million dollars worth of equipment to a Russian State company. Talks went smoothly but differences remained. So Martin Bayer himself, the CEO of the German Company, decided to come to Moscow to head the talks. Besides caring about his business, the CEO wanted to go to Russia to hunt bears.
Martin Bayer was one of the greatest hunters of our time (and the Russians knew about it). He went to the Sahara more than hundred times and hunted lions, crocodiles; he hunted polar bears in the North Pole and tigers in the rain forests of India. But he had never hunted Russian bears.
So the Russians decided to organize a bear hunt for Mr. Bayer to sweeten the talks. This wasn't a simple task. Some people in the west still believe that bears may be found and seen everywhere in Russian cities just like squirrels may be seen in our back yards. This is not true. The closest place one may find bears in the wild is maybe 2,500 miles away from Moscow. However, a solution was quickly found. The Russian businessmen went to Moscow Circus（马戏团）and for $2,000 bought a very old bear. This bear used to amuse and amaze audiences in many countries for 30 years, but got and looked too old, and was retired.
“Be careful, the Russian bears are very dangerous, and frightening,” they told to Mr. Bayer. “If compared to the Russian bears, your African lions are nothing more than harmless cats.” The bear was brought to a forest 50 miles from Moscow and was left there. Mr. Bayer was told that bears were plentiful in that forest and that many cattle and even people had been eaten in the surrounding villages.
Meanwhile, an 18-year old female drove through the forest on a motorcycle and suddenly saw a bear (no bears had been seen in those places for 200 years). She was frightened, fell, left her helmet and her motorcycle and ran away.
Mr. Bayer was excited and ready to hunt. This could become the most successful part of his extraordinary hunting experience. The next moment Mr. Bayer saw a bear in a helmet driving on a motorcycle through the forest in front of him. The bear had a happy expression on his face, as he was doing something he had been doing in the circus for 30 years: circling on a motorcycle!
Mr. Bayer lives in a private mental institution near Hamburg happily ever after. The equipment was never sold to Russia. It was sold to Iraq instead.
1. Why did the Russians invite Mr. Bayer to hunt bears?
A. Russian bears are famous for their cruelty.
B. They managed to find a bear for hunting.
C. They expected the trade to be successful.
D. There was a bear in Moscow Circus.
2. Why did the Russians say “Be careful, the Russian bears are very dangerous, and frightening”?
A. To tell Mr. Bayer that many people had been killed by bears.
B. To make Mr. Bayer feel the hunting really challenging.
C. To warn Mr. Bayer to mind his safety while hunting.
D. To tell Mr. Bayer that the bear is really dangerous.
3. We can infer from the last paragraph that __________.
A. Mr. Bayer has gone ma   
B. the bear injured him badly
C. he has worked in a mental institution since then
D. the trade has gone smoothly between Russian and Iraq
4. Which would be the best title of the passage?
A. Mr. Bayer, a Brave Hunter     B. Russian Bears, Dangerous Animals
C. Don’t Hunt in Russia       D. Don’t Deal with the Russians
