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.

ATLANTA, Georgia--- Alternative medicine --- including yoga, meditation, herbs（草药）and the Atkins diet（艾特金斯饮食法）---appears to be growing in popularity in the United States, perhaps because of dissatisfaction with conventional care, the government said Thursday．

       More than a third of American adults used such practices in 2002, according to the government survey of 31,000 people, the largest study on non-conventional medical approaches in the United States．If prayer is included, about 62 percent of U．S．adults used some form of alternative medicine．

       The results seem to indicate more people are turning to alternative medicine, though the 2002 survey could not be directly compared to previous studies because of differences in size and survey methods, health officials said.

       The top alternative therapies（疗法）included prayer （43 percent of adults） , natural products（19 percent）,meditation（8 percent）and diets such as Atkins, Ornish, or the Zone（4 percent）．More people also are using natural products such as herbs or enzymes（酶）to treat chronic or recurring pain（慢性或经常性疼痛）,said Richard Nahin of the National Center for Complementary and Alternative Medicine, part of the National Institutes of Health．

       “Many conditions are not easily treated with conventional medicine,” Nahin sad. “It may be the public that is turning to complementary（补充的）and alternative medicine because it’s not getting relief from conventional medicine．”

       But people should not be turning away from conventional treatments that are proven safe, said Dr．Stephen Straus, director of the alternative medicine center．

“People are making individual decisions to neglect those therapies and we have concerns about those choices,” he said.

       Health officials said they were concerned that 13 percent of those surveyed said they turned to alternative medicine because regular medicine is too expensive．

       “It needs to be explored ---we need to find out whether they were insured or not” Nahin said.

Health officials also were surprised that 6．6 percent of those surveyed used the supplement kava（卡瓦提取物）, which has been associated with liver disease．

       “People make the assumption that because something is natural that it’s safe” Nahin said.       “But a number of studies have shown that natural products can be unsafe when used inappropriately or with other drugs．”

He said people considering using alternative medicine should consult their doctor first．

1．Which can be used as the proper title for the passage？

      A．Differences between alternative medicine and conventional medicine

       B．Comparison of the effects of different medicine

       A．because it has been proven safe to take

      B．because experts confirm it all sidedly

      C．because they are not satisfied with the conventional medicine

      D．because conventional medicine is expensive

3．What can probably be inferred from the passage？

      A．Most patients are blind in taking alternative medicine or conventional care．

       B．Experts still haven’t drawn an all-round and exact conclusion about alternative medicine．

      C．Alternative medicine will eventually take place of conventional care．

      D．Natural herbs are safer than the medicine processed by man．

4．Which of the following agrees with the article？

      A．Experts will carry out further studies on alternative medicine．
