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 don’t get such a bad disadvantage in immune system. But if the body isn’t 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.

The coronavirus outbreak has sparked panic buying of toilet paper and cleaning products in countries across the world, but one UK businessman is determined to spread some happiness among the anxiety and confusion.
Rob Braddick, 48, who owns Braddick’s Holiday Park in Westward Ho, Devon, in the southwest of England, has filled the toy grabber machines in his amusement park with two of the country’s most sought-after cleaning products.
Customers could previously try their hand at grabbing “Frozen 2” or “Peter Rabbit” toys from the machines, but no more. “They got removed this morning,” Braddick said of the toys, replacing them with toilet roll and hand sanitizer (洗手液). Visitors can now pay 50p for three goes on the toilet roll grabber, or a go for Carex, which Braddick described as the “Rolls- Royce of hand sanitizers.”
Braddick said that his decision was born of a desire to make people feel less stressed in uncertain times. “It’s a bit of light relief with everything that’s going on,” he said. “Hopefully it will raise a smile, which I think everybody needs.”
Around the world, travel plans have been severely affected, and tens of millions of people remain at home as part of global efforts to fight against coronavirus. Supermarkets have seen shortages of toilet paper and hand sanitizer as anxious consumers stockpile the products.
Braddick said the family business, which has been running since 1932, has received more than a dozen calls from potential customers who say they don’t want to travel abroad for their holidays and would rather stay in the UK. As for his own measures against coronavirus, Braddick said staff have been told to wash their hands every half hour, which is particularly important for those handling money.
1.What is the third paragraph mainly about?
A.New practice of the game. B.Prizes of the game.
C.Price for a try. D.People’s love for grabbing toys.
2.What’s the purpose of Braddick’s new idea?
A.To make higher profits. B.To attract more people to play the game.
C.To support his family business. D.To ease people’s anxiety.
3.What can be inferred from the passage?
A.Cleaning products will be in shortage for a long time.
B.Braddick’s business is experiencing a hard time.
C.Tourism may fall into a decline.
D.Everyone in the park is told to wash their hands every half hour.

Welcome to Olympic National Park!
The park is located in the western state of Washington and it covers more than 400,000 hectares. Each area of the park offers visitors something special. Here are some places to go.
Elwha Valley
The Elwha Valley is in the central part of the park. It is the Olympic Peninsula’s largest watershed (分水岭). Long ago, the rivers in this area held the most salmon (鲑鱼) outside of Alaska. In the 1920s, a growing community of settlers built two hydroelectric (水力发电) dams to provide energy for the local economy. The dams created many problems for the river. They decreased the water in the rivers, which caused the fish population in the area to decrease. This affected the other animals that depended on fish for food.
The community later decided to take some measures to solve these problems. Today, the Elwha River is the site of one of the largest ecosystem restoration projects in National Park Service history.
Hurricane Ridge
Hurricane Ridge is a mountain area in the northern part of the park. It is easy to enter, and provides incredible views of the Olympic Mountains.
The ridge has many hiking paths. In winter, people come here to ski. They also come here to take part in other fun winter activities, like sledding and snowboarding.
Hurricane Ridge usually has snow from December through the end of March. Visitors must be prepared for icy roads and severe weather.
The Coast
The westernmost part of the park is Pacific coastline. Olympic National Park has many breathtaking beaches.
Rialto Beach is known for its tall seastacks (海蚀柱). These formations are tall towers of rock standing in the sea. Kalaloch Beach is known for its white sand. It also has three national wildlife refuges, which protect the area’s bird and fish species.
The coastline areas offer hiking and camping. They are some of the most popular places in the park.
1.What happened to the Elwha River after the two dams were built?
A. Local settlers had enough energy.
B. Local settlers made more money.
C. The Elwha Valley was formed.
D. The ecosystem was greatly affected.
