The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim(受害者)of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve(保护区)itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation"s land area, official figures showed.
"The country"s natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average(平均水平) of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment(投资) in such reserves at all levels.

A Chinese man called Cai Lun invented paper almost 2,000 years ago. He took the wood from trees and made it into paper. He then put these pieces of paper together and made them into a book.
Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting nearly 48,000 trees every day. Since it takes more than 10 years for a tree to grow, we must start using less paper now.
So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can use cotton handkerchiefs and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant gives us a paper bag, we can save it and reuse it later.
Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.

A.discovered Cai Lun invented paper | B.learned to make paper |

D.To grow more trees |
A.If we keep on wasting paper, we will have no paper to use one day. |
B.The Chinese used paper money much earlier than people in western countries. |
C.About 48,000 trees can be used to make 2,800 tons of paper. |
D.It is never too late to plant trees for paper. |
A.Saving Paper | B.The History of Paper |
C.Cotton Handkerchiefs Back Again | D.Cai Lun, the Inventor |
Why should man take the trouble of conquering space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way. The areas that will benefit are manifold. They include communication, generation of power, transportation and travel, food production, materials, fuels and many others. But to say definitely just what the practical results will be is almost impossible.

The most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.
The official origin of East-West trade along the road is usually placed in the late 2nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission(使命)across the desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthian for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury (奢侈品) markets in Rome.
But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.
小题1:The word “coupled” in the first paragraph could best be replaced by .
A.combined | B.contributed | C.doubled | D.produced |
A.Egyptians had probably travelled to China to buy silk |
B.new light can now be thrown on ancient trading practices |
C.historical research often achieves fascinating results |
D.trade along the Silk Road began earlier than once thought |
A.began a million years ago |
B.primarily benefited the Egyptians |
C.originated in the 2nd century BC |
D.extended human migration into eastern Asia |
A.he discovered the Silk Road |
B.he helped establish East-West trade |
C.he travelled as far as Afghanistan |
D.he brought back knowledge of Rome to the emperor |
