The deadliest Ebola(埃博拉病毒) outbreak inrecorded history is happening right now. The outbreak is unprecedented(空前的) both in the number of people who have gotten sick and in the geographic scope. And so farit's been a long battle that doesn't appear to be slowing down.

    Ebola is both rare and very deadly. Since the first outbreak in 1976, Ebola viruses have infected thousands of people and killed roughly killed 60 percent of them. Symptoms can come on quickly and kill fast.

    The current outbreak started in Guinea sometime in late 2013 orearly 2014. It has since spread to Sierra Leone and Liberia, including somecapital cities. And one infected patient traveled on a plane to Nigeria, where he spread the disease to several others and then died. Cases have also popped up in various other countries throughout the world, including in Dallas and NewYork City in the United States.

    The Ebola virus has now hit many countries, including Guinea, Liberia, Sierra Leone, Nigeria, Senegal, and the United States. The virus, which starts off with flu-like symptoms and sometimes ends with bleeding, has infected about 6,500 people and killed more than 3,000 since this winter, according to the World Health Organization on September 30, 2014.

    There are some social and political factors contributing to the current disaster. Because this is the first major Ebola outbreak in WestAfrica, many of the region's health workers didn't have experience or trainingin how to protect themselves or care for patients with this disease.

    Journalist David Quammen put it well in a recent New York Timesarticle, “Ebola is more dangerous to humans than perhaps any known virus on Earth, except rabies(狂犬病) and HIV. Andit does its damage much faster than either.”

    Hopefully, researchers are working to find drugs, including a recent $50 million push at the National Institutes of Health. And scientists are working on vaccines(疫苗), including looking into ones that might be able to help wild chimpanzees, which are also susceptible to the disease. The first human Ebola vaccine trial is scheduled to start in the spring of 2015.

To be successful people

    Here are some opinions about successful and unsuccessful people.

    Make life plans and set goals

    You can't be successful without knowing where you are going. A life vision board, 10 years' plan and daily goals are useful tools of the successful people. {#blank#}1{#/blank#}

    Keep a "To-be" list for the future

    A "To-be" list is a great way to plan for the future. I want to be an elected official in the future. I want to be the CEO of a public company. {#blank#}2{#/blank#} Unsuccessful people have no idea what they want to be. How can you achieve success if you don't know what you want to be?

    Study every day

    {#blank#}3{#/blank#} Whether you are reading a magazine or a good book. You can learn and become knowledgeable as you read. While watching television may be good entertainment, you will hardly get anything out of TV to help you become more successful.

    Want others to succeed

    When you are in an organization with a group of people, in order to be successful, you all have to be successful. {#blank#}4{#/blank#} If you wish for their failures, why even work with them at all?

    Accept responsibly for your failures

    Where there are ups, there are most always downs. Being successful persons means always having to accept responsibly for your failures. {#blank#}5{#/blank#} It just puts other people down and no good comes from it.

    Smith entered Mr.Watson's office.The boss was a hard man.He fired people who didn't do well without giving them a second chance.

    “Smith，” said Mr.Watson，“this past year your department hasn't earned money.We're going to drop that department.It's finished.I'm sorry，—but you'll have to go.” “But，sir—if I just had a little more time.For the moment I need the job to keep my son at Riverside School.”

    “What's that！” said the boss.“Riverside！I didn't know you had a boy there.That's an expensive school for a man with your salary.”

    “I know，sir.But he likes it there so much！He's a star athlete and the best boxer in the school.The boys call him Champ (冠军)there.”

    The boss sat perfectly still for a long time—a faraway (恍惚的) look in his eyes.Then，suddenly，he said，“We've got to close your department，Smith. But you'll take over a new job in another department.It means longer hours—maybe more pay.Now get out.You're here for life.”

    Smith got out，with surprise on his face.Then the boss took a letter from the top drawer of his desk.It was Herbie's last letter from Riverside School—written a few days before he died.He had read it over and over again with sick pain.The letter read：

    I can't say the boys here are any nicer to me than the others were.I guess it's the same everywhere when you're a cripple (跛脚的人)．But don't worry about me，Dad.They've got a good chemistry department here.And there's one boy here who is really great.He's a track star and boxing champ and just tops in chemistry.The boys call him Champ.He made them stop throwing my books around.And he knocked a boy down who hit me.He is the best friend I ever had.Dad，when I grow up，I want to do something for Champ.Something big—that he won't even know about.

You might think people all over the United States have Wi-Fi—wireless Internet service—and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the U.S. capital, Washington D.C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

    There is a ban on Wi-Fi in Green Bank, along with anything else that can create electromagnetic(电磁的)waves. Officials say the waves could disturb the signals the telescope receives.

For many Americans, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs—because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

    The observatory(天文台)is one of the largest employers in the area. The federal National Science Foundation(NSF) spends about ＄8.2 million a year to operate the observatory, telescope and educational center.

    Jonah Bauserman is a technician. If he supposes there is signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

    People in the town respect the work of the scientists. And they say they are happy to live without Wi-Fi and mobile phones. "You know, instead of sitting here on our phones and other devices we're out fishing and hunting and going to each other's houses." Everyone knows each other and communication is almost always face-to-face.
