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 (調(diào)節(jié)) 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(靈長(zhǎng)類(lèi)). 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 (電解質(zhì)) 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.

Shirley Temple Black, who lifted America’s spirit as a bright-eyed child movie star during the Great Depression, peacefully passed away at her California home on Monday evening at 85, surrounded by her family and caregivers.
Temple, born on April 23, 1928, started her entertainment career in the early 1930s and was famous by age 6. Temple was 3 when her mother put her in dance school, where a talent scout spotted her and got her in Baby Burlesks, a series of short movies with child actors playing in adult movies.
Movie studio directors took notice of her and in 1934 she appeared in the film Stand Up and Cheer! and her song and dance caught people’s attention. Movies such as Little Miss Marker and Bright Eyes featured her signature song. In 1935, she received a special Oscar for her “outstanding contribution to screen entertainment” in the movie Stand Up and Cheer!
She made some 40 feature movies, including The Little Colonel, Poor Little Rich Girl, Heidi and Rebecca of Sunnybrook Farm, in 10 years, starring with big-name actors like Randolph Scott, Lionel Barrymore and Jimmy Durante. Temple was a superstar before the term was invented. She said she was about 8 when crowds shouting their love for her made her realize she was famous. “I wondered why,” she recalled. “I asked my mother and she said, ‘Because your films make them happy.’ ”
Her child career came to an end at 12. She tried a few roles as a teenager—including opposite future president Ronald Reagan in That Hagen Girl – but retired from the screen in 1949 at 21.
Temple was only 17 when she married for the first time to John Agar, who would eventually appear with her in two movies. Their five-year marriage produced a daughter. In 1950 she wed Charles Black in a marriage that lasted until his death in 2005. She and Black had two children. Temple’s interest in politics was sparked in the early 1950s when her husband was called back into the Navy to work in Washington.
1.For which movie did Shirley Temple win the Oscar?
A. That Hagen Girl
B. Little Miss Marker
C. Stand Up and Cheer
D. The Little Colonel
2.When Temple first caught the audience’s eyes, ____.
A. she hoped to play a role in a series of movies
B. her family was offered
C. her mother sent her to a local dance school
D. the United States was in fact in financial straits
3.After Temple got married to Charles Black, ____.
A. she might have begun her political life
B. she had to raise her two young children
C. she decided to work for the Navy
D. she ended her film career on screen
4.It can be inferred from the fourth paragraph that ___.
A. people could find happiness in Temple’s films

【改編】Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal (玫瑰紅)was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer.
Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma(黑瘤), a type of skin cancer. More than 1,200 Australians die every year from the disease.
Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment.
“We believe it works by getting into the tumor(腫塊) cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It’s not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision(切除),”he said. “It’s useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred.”
About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal.
Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging.
Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg.
“I’ve had a lot of friends who just said ‘I thought it was just, you know, I’ll get a mole(痣) cut out and that’s it’, whereas I don’t think people realize how much danger they’re putting themselves into and how easy it is to stop something like this happening to you just from doing little things,”said Marock.
Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned(淺膚色的), are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.
1.Which can be the best title of the passage?
A. Rose Bengal —the cause of skin cancer.
B. Rose Bengal —a tool to fight against skin cancer.
C. Skin cancer—the first killer.
D. Melanoma—the threat to health.
2.What does the underlined word “fatal” mean?
A. Curable. B. Serious. C. Deadly. D. Self-healing.
3.From what Veronica Manock said , we can know _______.
A. people haven’t realized overexposure to the sun is dangerous
B. mole on the leg is dangerous.
C. people can do nothing to protect themselves from melanoma
D. nothing can be done to deal with the disease.
4.Who are likely to develop a melanoma?
A. Englishmen. B. Canadians.
C. Americans. D. Australians.
5.In which section of a newspaper does the passage possibly appear?
A. Economy. B. Agriculture. C. Health. D. Fashion.

Many families take their children on vacation. They will usually travel for a few days or weeks during school breaks. But Julie and Tim Rivenbark planned a longer vacation with their two children—the Rivenbark family is on a one-year trip around the world. They plan to visit 30 countries in all.
Right now, the four travellers are about halfway through their trip. Ms. Rivenbark says they are trying to see as much of the world as they can. She says “we have been through Europe, southern Africa, now we are kind of working our way through Asia. So we have been to a bunch of big cities, like Dubai, Johannesburg, Rome and Bangkok.”
The family has also spent time floating in kayaks(long narrow boats) in Italy, flying in hot air balloons in Myanmar, hiking to the Everest Base Camp in Nepal and going on a journey to see or hunt animals in South Africa.
Mr. Rivenbark says the family has also ridden on ostrich birds, elephants, and camels. But, he says, one of the most interesting experiences of the trip has been meeting new people.
“People have been extremely friendly, very welcoming and love our kids—interacting with them and their reaction to see our kids enjoying themselves in their country.”
Eleven-year old Tyler says he has enjoyed learning about the people they have met. “I learned in Africa that people have very different lifestyles compared to Americans.” His sister, 9-year-old Kara, discovered that she liked Thai food.
Ms. Rivenbark says that the extended trip teaches the children a lot more than short visits would have. “I think that the longer we travel, the more impact it has on how they see the world. I can see them changing more than they can see themselves.”
It took the family a year to prepare for the trip. They had to sell their house and cars. Ms. Rivenbark quit her job and her husband is using unpaid leave. They carry small bags filled with lightweight clothing and whatever else they need. Ms. Rivenbark says she enjoys being able to carry everything she needs on her back. She says she does not miss the things she has back home. “What has become more important is making these memories as a family and taking those with us instead.” Tyler and Kara each have iPads so they can communicate with teachers to stay current with their schoolwork. Tyler is also creating a 365-day video blog.
The Rivenbarks will continue to head east for the next six months. They plan to visit Laos, Cambodia, Vietnam, China and Australia. To follow their adventures, visit their website: earthtrekkers.com.
1.What makes the Rivenbarks different from other families is that _____.
A. they have their family trips during the children’s holidays
B. they have carefully planned their family trips for holidays
C. they plan to have a tour around the world without their children
D. they tour around the world with their kids not going to class
2.During the travel, _____ impressed the kids as well as the parents most.
A. floating in kayaks in Italy
B. hiking to the Everest Base Camp in Nepal
C. interacting with different people
D. riding on elephants and camels
3.The underlined word in Paragraph 7 extended is closest in meaning to _____.
A. expandedB. contented
C. shortenedD. intended
4.We can infer from the passage that _____.
A. It will take the family one year to prepare and finish their travel
B. The kids are finishing their current study with the help of the Internet
C. The family are likely to stay in Asia for the second part of their trip
D. To afford such a trip around the world is really something easy for the family
5.The passage is meant to _____.
A. share with the readers an extraordinary family trip
B. introduce some great parents and their jobs
C. remind us of the pleasure of getting close to nature
