Scientists say they have discovered a possible cure for all five known Ebola viruses. Antibodies (抗体) that are used in the cure were discovered in the blood of a survivor.
Kartik Chandran of the Albert Einstein College of Medicine helped discover the antibodies. They are described online in the journal Cell. Chandran says studies of the antibody in non-human primates (非灵长类动物) have shown positive results. He says he is optimistic that the antibodies can be used to protect and treat people, too.
he virus was given the name Ebola because the first recorded outbreak of the disease took place along the Ebola River in the Democratic Republic of Congo (DRC) — then known as Zaire
— in 1976.
Since then, there have been about 24 Ebola outbreaks in Africa, including one happening now in the DRC. Nine people have been infected and three people have died. The most recent Ebola epidemic took place from 2013 to 2016. It killed more than 11,000 people and infected
29,000 in Liberia, Guinea and Sierra Leone.
During that epidemic, researchers were studying an anti-Ebola drug called Zmapp. Doctors began using it even before the study was complete. Zmapp uses antibodies discovered in mice. They use the body’s natural immune system to fight infection. If the drug is given within five days after Ebola infection symptoms appear, it can cure the disease.
Promising results
But researcher Kartik Chandran says Zmapp is effective only against Ebola Zaire. It does not fight the other four known Ebola viruses.
Chandran says the recently discovered human antibodies attack and destroy all five of the viruses. Researchers say the antibodies work by interfering with a process that the disease uses to infect and multiply inside cells. Chandran says scientists discovered the antibodies in just six months.
The drug company Mapp Pharmaceutical Incorporated is now testing the antibodies in monkeys that have been exposed to Ebola. Spokespeople for the company say the antibodies have
so far been safe and effective．
Chandran says he hopes the antibodies can also be tested in people soon. And, he says, he hopes they can finally be used both as a treatment and as a vaccine (疫苗) to prevent people from getting Ebola in the first place.

Do you think telling lies, whether a little or a lot, isn’t that big of a deal? Well, that depends on the situation. If someone asks, “Does this dress make me look fat?” we might all lie somewhat. We might say, “Of course not. You look great.” Lying to spare someone’s feelings is one thing. Lying to destroy someone’s character or fame is another.
“What’s really terrible is that you can’t undo a big lie,” says a minister we’ll call Morgan. “I promise if you go house to house to say, ‘I feel terrible I wrongly accused my neighbor of stealing,’ the lie will spread like a fire fueled by gasoline. You can’t call back a lie very easily.”
Morgan goes on to say that lies have hurt people more than guns.
“We have a grandfather in our church whose former son-in-law told people the man treated his own children cruelly,” Morgan says. “To this day, we don’t know whether it is true or not. I would tend to doubt it, but I can’t take a chance, especially if he is working with young people in our church.”
Disarming someone who lies is tough. It’s like disarming someone who’s prepared to fire.
That’s why our society is full of people who are forced to cover up the lies of other people.
“I worked with a man who was stealing money from our employer,” says a man we’ll call Fred. “He was so good at lying and doctoring the books (做假账) that it would have taken an FBI agent to stop him. I worried, ‘If I turned him in, and he got out of the trouble, my career at our company would come to an end.’”
Fred says he came up with a plan to drop hints ( 暗 示 ) to the company owner. “I found printed materials on monitoring possibly dishonest employees. I started mailing them to the company owner without leaving my name. Then one day, over lunch, I told my boss he should have the books checked carefully. He got the hint.”
Fred told us that when the books were checked, the dishonest co-worker tried to blame him for the errors. However, Fred told the company owner he had been dropping hints for some time. The boss got the picture. Fred kept his job. The dishonest guy was fired.
Figuring out how to make a liar public takes work. It can be done, but you might have to move at the pace of a turtle. The slower you move, the more control you will have. You have to give others time to take in the truth.

A. By listing numbers.

D. By following order of time.
4.What can we know from the passage?
A. It was true that the grandfather treated his own children cruelly.
B. It is not difficult to persuade a dishonest man into telling the truth.
C. Fred’s boss believed the dishonest employee’s words and fired Fred.

Dear Mr. Baker,
Please find below, my impression of the Soundproof Swing concert last Sunday.
I’ve been to a half dozen Soundproof Swing shows in the last few years, but this performance at the Alice Motorplex was the most fascinating I have ever seen. It seemed an old place for a jazz concert, but it was full of energy. I have never seen them so chatty with the crowd! If they were trying to build up harmony, it worked. The audience ate up every note, chord( 和弦), word, and stanza. The atmosphere was simple electric, and the open air was a surprisingly fine compliment(恭敬) to the music, played masterfully as always. A good time was had by all! Check their website(www. Spswing.com) for the next tour stop!
Thanks for the opportunity! Love your magazine!
