An absolute description of the threat hanging over the world's mammals,reptiles,amphibians and other life forms has been published by the well-known scientific journal,Nature.A special analysis carried out by the journal indicates that an astonishing 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened.
Many species are already critically endangered and close to extinction,including the Sumatran elephant,Amur leopard and mountain gorilla.But also in danger of vanishing（消失）for the wild,it now appears,are animals that are currently rated as merely being endangered.
In each case,the finger of blame points directly at human activities.The continuing spread of agriculture is destroying millions of hectares of wild habitats every year,leaving animals without homes,while the introduction of newly-come species,often helped by humans,is also damaging native populations.At the same time,pollution and overfishing are destroying ocean ecosystems.
"Habitat destruction,pollution or overfishing either kill off wild creatures and plants or leaves them badly weakened," said Derek Tittensor,an ocean ecologist at the World Conservation Monitoring Centre in Cambridge. "The trouble is that in coming decades,the additional threat of worsening climate change will become more and more common and could then kill off these survivors."
The problem,according to Nature,is worsened because of the huge gaps in scientists knowledge about the planet's biodiversity.Evaluations of the total number of species of animals and plants alive vary from 2 million to 50 million.In addition,evaluations of current rates of species' disappearances vary from 500 to 36,000 a year. "That is the real problem we face," added Tittensor. "The scale of uncertainty is huge."
In the end,however,the data indicate that the world is heading cruelly towards a mass extinction-which is defined as one involving a loss of 75% of species or more.This could arrive in less than a hundred years or could take a thousand,depending on extinction rates.

Everyone needs a break, and vacations are not meant for serious study. 1.The Spring Festival is coming up so this is the perfect time to discuss some great English language literature to take on a long train journey.
Before getting into the recommendations, you need to determine your English reading comprehension level. If you’re at the beginner level, there are two options: reading a children’s book or reading a book that you’ve read in Chinese translation. 2. If you’re at the intermediate level, popular books like pop fiction, mysteries and thrillers are good options. For advanced readers, classic works of literature or modern prize winners (Nobel, Pulitzer) are good options.
3. When I pick up a book I like, even though the first few chapters are really hard to get through, I would try to get accustomed to the language the author uses. Generally, after the first few chapters, things get a lot easier, especially if I get involved in the story.
Another great way to keep yourself motivated is to find a friend who’s interested in reading the same book. You can make goals that you both want to achieve. 4.
Some quick recommendations: Harry Potter, start with the first book and go on from there; the Narnia series; anything by U.S. writer Michael Crichton; and if you like horror, U.S. writer Stephen King is always unusual and fun. 5. Happy reading!
A. If you pick a book which is so challenging, it will be too stressful.
B. The most important thing is to pick a book that you’re really interested in.
C. You may also enjoy your reading when hanging out with your family.
D. You should just find a topic or author you’re interested in, and the rest will go from there.
E. You can also discuss plot lines or vocabulary issues with each other by SMS or e-mail.
F. Instead, they’re a great way to take a break and enjoy a good book.
G. This will help you get over any unfamiliar words or phrases, since you’re already familiar with the story.
