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.Ebola causes the death of a human being by ________.

Before Nicholas Clapp got there, he had half hoped that he might run into some of Ubar’s ruins sticking(凸出) out of the sand. But finding the city wasn’t that easy. During the summer, he and his 40 helpers dug at 35 different spots. The only things they found were ground spiders, giant ticks, and deadly snakes.
Just before Thanksgiving says Clapp, “We were within a whisker of total failure.”
But then Clapp’s team looked at the high-tech maps again and saw something surprising. Many of the caravan routes(沙漠商队路线)on the high-tech maps came together on the same spot marked “Omani Marketplace” on Ptolomy’s map. Two maps, made almost 2000 years apart, pointed the team toward the same area!
In December 1991, Clapp arrived at the spot where, according to the maps, the caravans met. Clapp had a handheld instrument that could detect(探测) objects below the ground. It showed ruins under the sand! He and his team started digging. And then they found it! A tower buried in the sand. They slowly unearthed a giant, eight-sided fortress(堡垒). It had nine towers and many rooms. People had lived in this fortress 2000 years ago. Outside its walls, they had found buried remains of nearly 40 campsites. They seemed to be camping areas for traders(商人).
More digging found shards, or pieces of pottery(陶瓷) from ancient Rome, Greece, China, Egypt, and Syria. Diggers and scientists agree that people were here for about 5000 years. Clapp and his team were excited as they continued to discover more pieces of the past that seemed to prove that it was the lost city of Ubar.
“We started with this hopeless myth(神秘),” says Clapp, “and then finally found the truth behind the myth.” But is this unearthed site really the once-great Ubar? Experts aren’t totally persuaded.
Donald Whitcomb is an archeologist(考古学家) at the University of Chicago. He doubts that Clapp really discovered Ubar. “There’s probably some truth to this myth,” he says. “But Ubar is described as a place with walls all made of gold, and the rubies and emeralds(宝石).” No gold or precious stones have been found by Clapp.
“I’m not sure whether they discovered Ubar because I’m not sure if Ubar really existed,” Whitcomb says.The following statements are true according to the reading EXCEPT_____.
| A．Clapp made this discovery with the help of caravan routes on the maps |
| B．Clapp made this discovery with the help of some high technology |
| C．Clapp was not sure that he had found Ubar |
| D．Donald Whitcomb was not sure if Clapp had found Ubar |
Which of the following is closest in meaning to the underlined part?
| A．We were ready for any failure |
| B．We were on the point of giving up hopes |
| C．We would never stop digging though there was difficulty. |
| D．We decided that we had failed to find Ubar. |
It can be inferred from the reading that Nicholas Clapp is _____
| A．a person of courage |
| B．a person of determination |
| C．a very young person |
| D．a person who is good for nothing |
Bringing Art into Hospitals.
The medical world is slowly realizing that the quality of the environment in hospitals may play an important role in helping patients to recover(康复).
As part of a nationwide effort in Britain to bring art out of the museums and into public places, some of the country’s best artists have been called in to change older hospitals and to soften the hard, modern buildings. Of the 2500 national health service hospitals in Britain, almost 100 now have collections of art in passages(走廊), waiting areas and treatment rooms.
These recent movements were first started by one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970’s. He felt the artist had lost his place in modern society, and that art should be enjoyed by more people.
A common hospital waiting room might have as many as 5000 visitors each week. What a good place to hold exhibitions(展览) of art! Senior held the first exhibition of his own paintings in the waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain’s first hospital artist, Senior was so much in demand that he was soon joined by a team of six young art school graduates.
The effect is amazing. Now in the passages and waiting rooms the visitors experience a full view of fresh colors, playful images(形象) and restful courtyards.
The quality of the environment may reduce the need for expensive drugs when a patient is recovering from an illness. A study has shown that a patient who had a view onto gardens needed half the number of strong pain killers compared with(与……相比) patients who had no view at all or only a brick wall to look at.Some best artists of Britain have been called in to_____
| A．set up new hospitals |
| B．make the corners of hospital collect paintings |
| C．bring art into hospitals |
| D．help patients recover from serious illness |

| A．patients no longer take drugs to kill their pains |
| B．patients don’t have to stay long in hospital |
| C．patients need fewer pain killers when they suffer from an illness |
| D．patients feel happy in hospital |
It can be inferred from the passage that_____
| A．the role of hospital environment is being recognized |
| B．hospital artists have done more than doctors |
| C．exhibitions attract more people in hospitals than in museums |
| D．the hospitals is a better place for people than the museum in Britain |
That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theater. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.
As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away any possible robbers(抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets.
About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck(垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, “Alisa Camacho?” I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eyes. “Is this what you’re looking for?” he asked, holding up a small square shape.
It was nearly 3 a.m. by the time I got into bed. I wouldn’t get much sleep that night, but I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were willing to help each other.How did the writer feel when she was walking home after work?

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time; if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’s. In the same way, children learn to do all the other things without being taught to walk, run, climb, whistle, ride a bicycle…They compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake. If it is a matter in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time in such routine(日常的) work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what he does not know.According to the passage, the best way for children to learn things is by_____.

People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days offer a chance to think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child-care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one stands for a living mother. A white one shows that the mother is dead. Many people attend religious services(宗教仪式) to honor parents. It is also a day when people whose parents are dead visit their graves. On these days, families get together at home and in restaurants. They often have outdoor BBQs for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephones companies and other stores do a lot of business during these holidays.Which is NOT a reason for children to show love and respect for parents?
