2．The World Health Organization reports a number of people have died of the Ebola virus in central Africa during the last few months．Ebola，also known as Ebola hemorrhagic （出血） fever or Ebola viral disease．is a rare and deadly illness with high death rates in humans and primates．The natural source of Ebola virus remains unknown，although bats seem to be the most likely source．
The Ebola virus began spreading after victims were discovered in northeastern Cabon．So far，it is the third time Ebola has spread through Cabon since 1994．Health officials believe people moving across the border spread the disease from Cabon co Congo Ebola is highly infectious and kills up to 80% of its victims．Researchers do not know the method with which the virus first appears in humans，but they believe it is through infected animals．The disease then spreads from person to person through blood and other body liquids．
Ebola victims treated early have the base chance of survival．Signs of Ebola include a high temperature，diarrhea，muscle pains and bleeding inside the body．in severe cases，victims experience chest pains and death．There is no known cure for the disease and no way yet to prevent it．
Scientists at the American National institutes of Health are working to develop a vaccine（疫苗） to prevent Ebola．Doctor Cary Nobel is leading the research effort at N-l-H testing center in the eastern state of Maryland．He says that during the past two years，the vaccine has been tested on small animals and monkey a for safety and effectiveness．
In the most recent study，four monkeys who had been given the vaccine were completely protected from a deadly injection of the Ebola virus．the study was described in November in Nature magazine．Doctor Nobel says the tests appear to have moved scientists one step closer to a vaccine for humans．

1．One day，Mr．Arnold was teaching a lesson，and things were going as normally as ever．He was explaining the story of mankind to his pupils．He told them that，in the beginning，men were nomads； they never stayed in the same place for very long．Instead，they would travel about，here and there，in search of food，wherever it was to be found．And when the food ran out，they would move off somewhere else．
He taught them about the invention of farming and keeping animals．This was an important discovery，because by learning to cultivate（耕作）the land，and care for animals，mankind would always have food steadily available．It also meant that people could remain living in one place，and this made it easier to set about tasks that would take a long while to complete，like building towns，cities，and all that were in them．All the children were listening attracted by this story，until Lucy jumped up：
"And if that was so important and improved everything so much，why are we nomads all over again，Mr．Arnold？"
Mr．Arnold didn't know what to say．Lucy was a very intelligent girl．He knew that she lived with her parents in a house，so she must know that her family were not nomads； so what did she mean？
"We have all become nomads again，"continued Lucy，"The other day，outside the city，they were cutting the forest down．A while ago a Gsherman told me how they fish．It's the same with everyone：when there's no more forest left the foresters go elsewhere，and when the fish run out the fishermen move on．That's what the nomads did，isn't it？9，
The teacher nodded，thoughtfully．Really，Lucy was right Mankind had turned into nomads．Instead of looking after the land in a way that we could be sure it would keep supplying our needs，we kept developing it until the land was bare．And then off we would go to the next place!The class spent the rest of the afternoon talking about what they could do to show how to be more civilized．
The next day everyone attended class wearing a green T-shirt，with a message that said"I am not a nomad!"
And，from then on，they set about showing that indeed they were not．Every time they knew they needed something，they made sure that they would get it using care and control．If they needed wood or paper，they would make sure that they got the recycled kind．They ordered their fish from fish farms，making sure that the fish they received were not too young and too small．They only used animals that were well cared for，and brought up on farms．
And so，from their little town，those children managed to give up being nomads again，just as prehistoric men had done，so many thousands of years ago．
