An oral drug, named ERDRP-0519, was invented. It is specifically designed to protect people who got infected measles(麻疹) from spreading the virus to others. Like the flu, measles spreads through the air by breathing, coughing or sneezing. There is typically a time, about two weeks, between becoming infected with the virus and the beginning of symptoms like skin rash(皮疹), runny nose, heavy cough and high fever.
“This therapy application determines the desired characteristics of the drug, which are orally available, cost-effective manufacture and high stability,” Richard Klemperer, professor of Georgia State University, told reporters last Wednesday.
“With these criteria in mind, we have developed a small drug that blocks the measles virus over the past years, which is essential for copy of the virus.”
The researchers tested the drug in rats infected with canine distemper virus(犬瘟病) , which is a close relative of measles virus. They found that all of the infected rats treated with the drug survived the deadly infection, showed no clinical signs of disease and developed a strong protective immune response.
The drug could be used to treat friends, family and other social contacts of a person infected with measles virus, which have not developed symptoms yet but are at risk of having caught the disease, Klemperer said truthfully.
“The emergence of strong antiviral immunity(抗病毒免疫力) in treated animals is particularly encouraging, since it suggests that the drug may not only save an infected individual from disease but contribute to closing measles immunity gaps in a population,” Klemperer said.
The researchers emphasized the drug is not intended as a substitute for vaccination, but as an additional weapon to get rid of the measles. They planned to test the drug’s safety in larger animals, before moving into clinical trials in humans.
“If our next series of studies confirms that the human situation mirrors what we have seen in rats, then this drug may make a major contribution to getting rid of measles by preventing local outbreaks” Klemperer said.
Despite the existence of an effective vaccine, annual measles deaths worldwide have remained constant at around 150,000 since 2007. The reasons for this are the highly infectious nature of the virus, in the developing world largely due to issues of resources, and in many developed countries in particular in the European region due to parental concerns regarding vaccination safety.
1.If a boy got infected by measles virus, he might NOT show the symptom like ________.
A. runny nose B. bad cough
C. high fever D. sick stomach
2. From what Klemperer said, we know that the drug _________.
A. is only intended as a substitute for vaccination
B. can only save those infected individuals from disease
C. is cost-effective and high stability for curing measles
D. has the same effect on human as on larger animals
3.The best title of the passage is_________ .
A. the Introduction of a New Oral Drug
B. the Desired Characteristics of Drugs
C. the Common Symptoms of Getting Measles
D. the Application of Post-exposure Therapy

It may seem as if Mother's Day was invented by a company named Hallmark, but people have been taking time on the calendar to give a shout-out to Mom for a long time. The Greeks and Romans had mother goddess festivals — although their celebrations didn't involve the menfolk taking their underappreciated mothers out to dinner. A more recent tradition wasMothering Sunday, which developed in the British Isles during the 16th century. On the fourth Sunday in April, young men and women who were living and working apart from their families were advised to return to their mothers’ houses.
Mother's Day as it is observed in the United States started in the 1850s with Ann Jarvis, a West Virginia woman who held “Mothers' Work Days” to promote health and hygiene(卫生) at home and in the workplace. During the Civil War, Jarvis organized women to improve sanitary conditions for soldiers on both sides, and after the war she became a peacemaker, furthering the cause by bringing together mothers of Union and Confederate soldiers and promoting a Mother's Day holiday.
Jarvis's work inspired another 19th-century woman, Julia Ward Howe. In 1870 Howe published her “Mother's Day Proclamation”, which envisioned the day not as appreciation of mothers by their children but as an opportunity for women to exercise their collective power for peace. Howe started holding annual Mother's Day celebrations in Boston, her hometown, but after about a decade she stopped footing the bill and the tradition faded away.
It was Jarvis's daughter Anna who succeeded in getting Mother’s Day recognized as a national holiday. After her mother died, in May 1905, Anna started holding yearly ceremony on the anniversary and conducting a tireless PR campaign to have the day made a holiday. In 1908 she succeeded in enlisting the support of John W anamaker, the Philadelphia department store magnate and advertising pioneer, and by 1912 West Virginia and a few other states had adopted Mother's Day. Two years later, President Woodrow Wilson signed a resolution declaring the second Sunday in May a national holiday.
It wasn't long, though, before whatever ideals the day was supposed to celebrate were buried under an amount of greeting cards and candy. By the 1920s Anna Jarvis was campaigning against the holiday she had been instrumental in creating. “I wanted it to be a day of emotionalism, not profit,” she said.
1.The first paragraph suggests that .
A.mothers didn't get enough appreciation
B.Mother's Day was invented by Hallmark
C.young people returned to their mothers' houses
D.Greeks and Romans were the first to celebrate Mother's Day
2.Who plays the most important role in creating Mother's Day?
A.Ann Jarvis. B.Julia Ward Howe.
C.Woodrow Wilson. D.Anna Jarvis.
3.Why did Anna Jarvis object to Mother's Day at last?
A.Because it was an emotional day.
B.Because the festival was not profitable.
C.Because the celebrations went against the original spirit.
D.Because the day was buried under greeting cards and candy.
4.Which of the following would be the best title for the passage?
A.The Objection to Mother’s Day
B.The Argument on Celebrating Mother's Day
C.The Story Behind the Creation of Mother's Day
D.Different Form of Celebrations on Mother's Day

It was an international drug dealing case, one that involved a lot of money and a lot of violence. Agents who had entered the organization had worn wires and collected evidence for years. A conviction(法庭判决) depended on an accurate translation of their tape recordings. “Five languages were involved, “says Liz Elting, 44, one of the owners of TransPerfect, the translation company chosen for the job. “The slightest mistake could mean the criminals would go free.”
When Elting started her business 18 years ago with Phil Shawe, both were attending New York University’s Stern School of Business. Neither realized just how many situations would require their services. TransPerfect’s 4,000 linguists(通晓外语的人) cover more than 100 languages.
Getting Ahead with Liz Elting
What inspired you to start TransPerfect?
When I was eight, my dad bought a KFC in Portugal. Unfortunately, the Portuguese didn’t want anything American. They thought my dad was a CIA spy! That taught me how fast things can change. I’ve studied in Spain and worked in Venezuela. This business is the perfect combination of my love for languages, cultures and business.
Is the staff multilingual?
Many are. I speak French and Spanish. My partner, Phil, who is American, likes to say he speaks English on a good day.
What languages are requested most often?
Spanish and Japanese. Chinese, Middle Eastern, Indic(South Asia), and Eastern Europeans are on the rise.
How difficult is it to manage such a diverse workforce（员工团队）?
Our challenge is to be culturally appropriate in every country. When we hand our year-end bonuses in the US, for example, we have to remember that in India, bonuses are given in the fall.
Any advice for someone starting a business?
Get started before you have kids. In the beginning, I didn’t know how to do this business on the side. I wasn’t married, didn’t have kids, and wasn’t concerned about balancing my work and personal life. Now, with strong managers in place, I can spend more time with my family (husband Michael Burlant and sons Zachary, nine and Jacob, seven), traveling and playing baseball.
1.What is the purpose of the first paragraph?
A. To report on an international drug dealing case.
B. To encourage people to start a business before they have kids.
C. To present the importance of learning foreign languages.
D. To introduce Liz Elting and her company TransPerfect.
2.What does the underlined word “wires” mean in the passage?
A. A type of clothes costing a lot of money.
B. A piece of equipment designed to record messages.
C. Thin metal worn to protect yourself against violence.
D. A organization symbol made of thin metal.
3.Neither realized just how many situations would require their services. is ______________.
A. a company that offers international legal services
B. one which has branches in countries all over the world
C. one whose staff all have to speak several languages.
D. a company whose services are in great demand.
4.It can be inferred that _______________.

It is amusing that yogurt, which was invented to make milk last longer before the days of refrigeration, now makes grocery shopping last longer. Full-fat, or nonfat? Greek, or regular? 1.
A key recommendation when it comes to fat is to choose low-fat or fat-free yogurt. That's because dairy fat is mostly saturated (饱和的), the type linked with increased risk of heart disease. Besides, full-fat dairy has more calories than nonfat.
This view, however, has been challenged by a few recent studies. Researchers think that full-fat dairy might offer some as-yet-unknown health benefits. It might also help with weight management because the fat in it makes it more satisfying, helping keep our appetite in check.
2. Until there are further findings, it might be wiser to choose low-fat or fat-free yogurt and add healthy fat by topping it with nuts.
3. Many of them also have a hard time deciding whether to buy Greek yogurt or regular yogurt. Greek yogurt, which was rare about a decade ago, dominates the store shelves with dozens of flavors today. It has become popular partly because it features a thick, creamy texture (口感) and contains more protein and less sugar than regular yogurt.
Greek yogurt has these qualities because of its unique liquid-removing process. Unfortunately, lots of nutrients, including calcium (钙), are sometimes drained, too. Therefore, thickened yogurt and regular yogurt offer different nutritional benefits. 4.
Finally, it is worth mentioning that it's the added sugar, not the naturally- occurring sugar (which is removed in Greek yogurt), that should be the cause of our concern. Fruit-flavored yogurts that appear to be healthy may have little actual fruit and plenty of added sugar instead. 5.
A.Consumers, however. are not confused only about fat.
B.Mixing them up and enjoying both might be a good idea.
C.With so many conflicting headlines about fat these days, it's no wonder people are confused when buying dairy products.
D.Our best bet might be to buy plain yogurt and sweeten it ourselves using fresh fruit.
E.There are so many choices that we often find it hard to decide which yogurt to buy.
F.They're naturally ''packaged'' with so many important nutrients that it would be misguided to avoid them.
G.Yet more research needs to be done for us to fully understand dairy fat’s health impact .

My name’s Geoffrey Chaucer. It was 16th April 1386, and I was in London at an inn in Southwark. Tomorrow I would go to Canterbury, to the shrine (圣地) of Saint Thomas Becket, together with twenty-nine other people. Before I say more, I want to tell you about some of the people with me.
First there was a knight, a good man who fought well and knew many different countries. He was a true friend to everyone, and always helped people when they needed it. His clothes were old, dark, and dirty from many years of fighting.
Then there was a businessman with an expensive hat on his head. The man, who looked wealthier than he truly was, always said, “I’m doing very well.” A very quick thinker, he talked about ships and the sea a lot, and showed much interest in changing money from different countries.
After the businessman came a franklin (乡绅) with a white beard. He asked people from near and far to visit him at home as he liked eating and drinking and having a good time with others. He was an important man, he knew right from wrong, and people listened to him.
There was a woman from Bath. Her face was open, and nice-looking, but she couldn’t hear very well. In her red dress, she was a big woman with a big smile and big teeth, laughing a lot and talking easily. She knew all about love.
So there we were, all thirty of us, at the inn. The landlord, a tall fat man, brought us the best dinner in London. He would also join our journey tomorrow. After we finished eating, the landlord smiled, suggesting “We’re going to Canterbury tomorrow, and that’s four days from here. One by one, let’s all tell a story on the road to make the time go quicker. And to the teller of the best story we can give a free dinner here at my inn when we get back. What do you say?” We all said “yes” happily to him. Then the question for us was: Who goes first?
1.Which of the following can be described as kind-hearted?
A. The knight. B. The businessman.
C. The franklin. D. The woman.
2.Which is TRUE of the people described in the text?
A. The knight always wore very expensive clothes.
B. The franklin usually spent time on his own.
C. The woman was deaf and loved the red color.
D. The businessman was not as rich as he seemed.
3.The underlined sentence most probably means “______”.
A. Who will be the first to be served at the inn
B. Who will be the first to tell a story on the road
C. Who will go at the front of the traveling group
D. Who will be the leader of the traveling group
4.According to the text, Chaucer would probably arrive in Canterbury on ______.
A. April 19th B. April 20th
C. April 24th D. April 28th

Preparing for Oral Exams
The oral exam is an opportunity for you to demonstrate your knowledge, your presentation/speaking skills, as well as your ability to communicate. 1. The exam can be formal, or informal, but you should consider all exams formal exchanges in order to make a good impression.2.
To do well on an oral exam requires a rather different set of skills than those called for on a written exam.3. Here are some ideas on what you can do to prepare:
Learn the requirements and criteria. When you are preparing for oral exams, you shouldn’t be doing it in the dark.4. You should ask your teachers and advisers, and if you are taking a standardized exam, you can even contact the authority that is organizing and collect that information. Usually this information is not a secret and your teachers would gladly explain to you what they expect to see during the examination in order to give you a good mark.
5. Get together in a small group or in pair. Ask each other the questions and actually take the time to verbally answer them. You will not get it right the first (or the second) time. Revise your outline to help you get a better track, and then try again. Discuss answering techniques with people in the field or who have had the test, which will give you the courage to face your oral exam with confidence.
A. Practice for the exam.
B. Learn something new.
C. It can also be good practice for job interviews!
D. So you should master some of them and aim at using them properly.
E. This means that you should make an active effort to learn that information.
F. For both types, you must listen carefully to the question, and answer directly.
G. So some previous experience is helpful: teaching, debating, oral presentations, class participation, etc.

I have forgotten the name of an old lady in my home town when I was a twelve-year-old boy. Yet it dwells in my memory that she taught me a lesson in forgiveness that I shall never forget.
On a winter afternoon, a friend and I were throwing stones onto the roof of the old lady’s house. As a result, the stone headed straight for a small window. We knew we were in trouble. We ran faster off her roof.
I was too scared about getting caught to be concerned about the old lady with the broken window in winter. However, a few days later, I started to feel guilty for her misfortune. She still greeted me with a smile each day when I gave her the paper, but I was no longer able to act comfortably.
I made up my mind to save my paper delivery money. In three weeks I had the seven dollars and put the money in an envelope with a note explaining that I was sorry for breaking her window and hoped that the seven dollars would cover the cost for repairing it. After that, I walked up to the old lady’s house secretly, and put the letter I didn’t sign through the letter hole. My soul felt relieved and I could have the freedom of, once again, looking straight into the old lady’s kind eyes.
The next day, I handed the old lady her paper and she thanked me for the paper, giving me a bag of cookies she had made herself. I thanked her and continued to eat the cookies while walking.
After several cookies, I felt an envelope and pulled it out of the bag. When I opened the envelope, I was shocked. Inside were the seven dollars and a short note that said, “I’m proud of you.”
1.What does the underlined word “dwell” refer to?
A. Appear. B. Change.
C. Happen. D. Exist.
2.What happened when the author and his friend were throwing stones?
A. The roof of the old lady’s house was broken.
B. The stone broke a small window of the old lady’s.
C. The old lady broke into her house secretly.
D. The old lady gave him a bag of cookies.
3.How did the author feel about his breaking the old lady’s window?
A. Lucky. B. Discouraging.
C. Regretful. D. Annoyed.
