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 Gabon. So far, it is the third time Ebola has spread through Gabon since 1994. Health officials believe people moving across the border spread the disease from Gabon to 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 monkeys 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.Where does the Ebola virus come from?

Scott Langteau has this message for kids: Spend less time playing video games.
It’s a message that many a mom and dad has tried to impress upon many a youngster （and some not-so-youngsters） who spends perhaps a bit too much time with game controllers in hand.
But the 40-year-old Langteau isn’t a parent．He’s experienced at video games — one who played producer on three “Medal of Honor” games and co-founded his own game development company.
Langteau has just published a children’s book called “Sofa Boy,” which tells the story of a kid who spends too much time sitting on the couch with controller held in hand and the rather terrible consequences that follow.
It’s a fairy tale plucked straight from Langteau's own experiences as a lad with a fondness for video games and his own bouts with a bit of game addiction．But first, Langteau would like to make one thing clear: “I’m not saying that you shouldn’t play video games．I think video games are great, I think they do great things for kids”．Instead, Langteau says his book is all about a little something called “moderation.（克制）”
“It’s about being well rounded,” he says．“Just like with anything else, we all need to make sure that there’s a variety in what we do.”
Video gamers can be rather bad-tempered when it comes to accepting criticism about their favorite entertainment．And understandably so．After all, most people who go around talking about the dangers of playing video games tend to be outsiders — people who don’t play video games and certainly don’t understand that they can be a valuable and healthy form of entertainment.
But Langteau and “Sofa Boy” seem to be in a unique position to deliver a message of gaming moderation that the young game-savvy（有经验的） masses might actually listen to．After all, this is a man who understands what it means to be a kid with a passion for games．His early experience has taught him a lesson.Scott Langteau published “Sofa Boy” to．
| A．share his great skills on games |
| B．warn kids against game addiction |
| C．tell about his fairy tale as a kid |
| D．deliver a message for games |

| A．Langteau advises the young to play games within limits |
| B．Langteau advises the young not to play games |
| C．playing video games ruins the future of kids |
| D．playing video games is of no benefit to kids |
Why are the video gamers not accepted by the outsiders?
| A．Because they are bad-tempered. |
| B．Because they are dangerous to others. |
| C．Because they do nothing but play video games. |
| D．Because the value of the video games is not understood. |
By saying “It’s about being well rounded” Langteau thinks．20090506

Frank Woolworth was born in Rodman, New York., in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be farmer. He took a short business course, and went to work as a salesman in a large city.
Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.
Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly form the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.
By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world.

Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families. （词数155）The early language had ________.
