The current Ebola (埃博拉病毒) outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus —about 60 percent of people infected with it have died.
How is Ebola doing its harm?
When a person becomes infected with Ebola, the virus damages the body’s immune (免疫的) cells, which defend against infection, said a researcher at Lancaster University. But if a person’s immune system can stand up to this attack, then he is more likely to survive the disease.
The patients that survive it best are those who dont get such a bad disadvantage in immune system. But if the body isnt able to get rid of this attack, then the immune system becomes less able to regulate (调节) itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death.
What are the common symptoms of the disease?
Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.
How to prevent the spread of Ebola?
Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient.
We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates(灵长类). If you’re in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side.
Wear protective medical clothing if you’re around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you’re around infected patients.
How Do People Survive Ebola?
Doctors don’t know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection.
Our suggestions include:
Maintain your electrolytes (电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you’re feeling pain.
1.Ebola causes the death of a human being by ________.
A. attacking him with high fever
B. regulating his immune system
C. damaging his immune cells
D. harming all his organs directly
2.What is NOT mentioned as the symptom of Ebola?
A. Fever and chills. B. Swallowing difficulty.
C. Loss of blood. D. High blood pressure.
3.In order not to be infected by Ebola, we should _________.
A. have the clothing of the infected cleaned
B. avoid eating wild animals like monkeys
C. not travel to Africa, America or Europe
D. stay at home without going anywhere
4.It is true that ________.
A. a certain number of people survive Ebola
B. human has found a special cure for Ebola
C. oxygen can save infected people’s lives
D. low blood pressure is surely caused by Ebola

The deadliest Ebola(埃博拉病毒) outbreak in recorded 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 far it’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 or early 2014. It has since spread to Sierra Leone and Liberia, including some capital 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 New York 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 West Africa, many of the region’s health workers didn’t have experience or training in how to protect themselves or care for patients with this disease.
Journalist David Quammen put it well in a recent New York Times article, “Ebola is more dangerous to humans than perhaps any known virus on Earth, except rabies(狂犬病) and HIV. And it 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.
1.According to the passage, which of the following about Ebola is true?
A. The Ebola outbreak now is the biggest one in history.
B. Ebola breaks out quickly but it is under control now.
C. Ebola is deadly and common so it kills a lot of people.
D. Ebola killed about 60 thousand people quickly in 1976.
2.The Ebola virus was brought to Nigeria by .
A. a flying bird B. an infected passenger
C. hot African weather D. a health organization
3.The last paragraph mainly tells us that .
A. it will be a huge waste when researchers spend lots of money finding a cure
B. the vaccines can be effective to wild chimpanzees but not to the humans
C. there will be an optimistic future in which we can defeat the disease
D. we can use the vaccine to cure the patients completely in 2015’s spring
4.What is the best title of the passage?
A. Ebola ---- The African Local Disaster
B. Ebola ---- The Newly-Found Disease
C. Ebola ---- A More Effective Vaccine
D. Ebola ---- The Deadly Virus Outbreak

The largest outbreak of the deadly disease Ebola(埃博拉) was caused by an infected bat biting a toddler, say a group of international researchers.
The 17-strong team of European and African tropical disease researchers, ecologists and anthropologists have spent three weeks investigating the outbreak of the disease in Guinea, Liberia, Ivory Coast and Nigeria. The researchers captured the bats and other creatures near the village of Meliandoua in remote eastern Guinea, where the disease began in December 2013. The boy was bitten and passed the infection on to his mother and both died within a week. The disease was then spread far and wide by the people who came to the funeral.
Most of the previous outbreaks have been caused by meat from dead infected animals collected by hunters who then sell it on. Fruit bats, however, are widely eaten in rural West Africa.
The team, led by epidemiologist(流行病学家) Herr Leendertz, a disease ecologist at the Robert Koch Institute in Berlin, are expected to publish their results in a major journal soon.
Herr Leendertz’s team believe that an infected straw-colored fruit bat brought the disease to Guinea. The mammals are known to travel long distances and usually settle in forests near cities. Herr Leendertz said, “ The evidence is not 100 percent and we can only say that it is possible. They can travel far in one night. I don't think an individual bat or colony(群体) migrated all the way from Congo or Gabon to West Africa. These big colonies are connected. There is a possibility for the virus to mix between colonies. The bats share the same fruit. It is likely not to have even been one species of bat. The virus may jump from one species to another."
If the bat theory is confirmed, the locals would try to destroy the colonies, which, Herr Leendertz says, would be an ecological disaster, because bats pollinate(传授花粉) plants and kill insects. And bat hunts would also only increase human contact with potentially infected animals.
1.What’s the purpose of the 17-strong team?
A. To look into the outbreak of Ebola.
B. To help the people who suffer from Ebola.
C. To help cure the infected boy of Ebola.
D. To make a study of the bats including fruit bats.
2.In Herr Leendertz’s opinion, ______.
A. people can do nothing to prevent the disease
B. the disease Ebola may jump from one species to another
C. the result of the research should be published immediately
D. the straw-colored fruit bats usually settle in forests in the rural areas
3.If the bat theory is confirmed, ______.
A. the disease Ebola will be controlled
B. all the fruit bats in Africa would be killed
C. plants would not be pollinated in the future
D. the ecosystem in Africa might lose its balance
4.What’s the main idea of this passage?
A. A toddler was bitten by a bat and died.
B. The disease Ebola is incurable at present.
C. An infected bat caused the outbreak of Ebola.
D. The deadly disease Ebola broke out in Guinea.
5.This passage can probably be classified as ______.
A. a science fiction B. a news report
C. a lecture essay D. an auto-biography

The deadliest Ebola outbreak in history that has so far killed almost 1000 people in Guinea, Liberia, Sierra Leone and Nigeria in West Africa has caused fear around the world.
The outbreak is unprecedented（空前的）both in infection numbers and in geographic scope. Officials from the World Health Organization (WHO) said earlier this month the outbreak “is moving faster than our efforts to control it”, reported CNN. So far, the battle against the virus doesn’t appear to be slowing down.
The Ebola virus is terrifying no matter where it strikes: It’s a disease with no cure that causes headaches and fever, severe diarrhea(腹泻), vomiting and bleeding and has been known to kill up to 90 percent of its victims.
It is understandable for people to be panicked, but those living outside Africa shouldn’t be particularly concerned about contracting the virus, says a Washington Post article.
This is because transmission of Ebola requires direct contact with an infected person’s blood, vomit or other bodily fluids during the period that he or she is contagious(接触传染的). It is something that is extremely unlikely for anyone but healthcare workers. The virus is not spread by coughing or sneezing.
Media outlets in the US and the UK are using terrifying headlines, wrongly claiming that people infected with the virus have traveled to their countries.
James Ball at The Guardian says the Ebola outbreak in Africa is tragic, but it is important to keep a sense of proportion. Other infectious diseases, including common influenza, are far, far deadlier.
1.What does the author say about the Ebola outbreak in West Africa?
A. It has caused thousands of African deaths.
B. Its spreading speed is beyond people's imagination.
C. It has already traveled to the US and the UK.
D. The fight against it is slowing down.
2.The Ebola virus is terrifying because ________.
A. it cannot be cured at the moment
B. it is easily infected
C. it spreads faster than any other infectious disease
D. it has caused more deaths than other infectious diseases
3.The underlined phrase in the last paragraph means
A. keep a secret B. stay calm
C. keep silent D. stay away from it
4.What is the author's attitude towards people's panic?
A. Objective. B. Supportive. C. Doubtful. D. Understandable.
