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

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

I love seeing Europeans line up in airports to applaud arriving refugees. But humanitarianism (人道主义) will not guide policy for long. We liberals need to argue from Europe’s self-interest: our continent has the need, the space and the ability to accept people.

Many European countries are gradually turning into old people’s homes. Germany, Italy, Spain and others have some of the lowest birth rates in human history. It is predicted that about one-third of their populations will be aged over 65 in 2050. Germany needs to import at least 350,000 people a year to keep its workforce stable. Suddenly, young ambitious workers are pouring into the country as if called by a genie (精灵) with a lamp. No wonder Angela Merkel, German Chancellor, has been more welcoming than David Cameron, British Prime Minister. But all over Europe, carers for old people are already in need. Norway found oil under the seabed but it would have been better off if it had discovered 50,000 nurses there instead.

Many rightwingers think we have reached our limits. This feeling is widespread. And it’s true that Western Europe is one of the most densely populated regions on earth. Indeed, density has long been Europe’s unique selling point: with so many people of different nations closely packed together, we have always traded goods and exchanged ideas fast. That’s why the scientific revolution of the 16th and 17th centuries happened here.

But we have plenty more room. Many European cities aren’t dense enough. Now east Germany, north-western Spain and gorgeous mountain villages in Italy are losing people. Lots of cities have unused industrial land.

Humans inhabit a slice of the EU’s territory. Only about 2.5 per cent of the EU’s land is used for housing, estimates the European Commission. By contrast, a whopping 43 per cent was used for agriculture in 2009, it says. That’s too much. We could turn more land into forest or into green landscapes where people can relax and play. Making that transition is feasible because we now use agricultural land inefficiently.

Migrants often spend years locked up together in serious government-funded “migrant centers”. However, the way to learn a new country’s language, make friends and find work is to live with a local. This crisis has shown that lots of Europeans are willing to take refugees into their homes. After Iceland’s government said it could take only 50 Syrian refugees, many Icelanders came forward offering to take a far greater number into their own homes. People aren’t just sitting around waiting for government to do something.

We need migrants, and we can accommodate them. If opponents just don’t like foreigners, they should say so instead of pretending to be hardheaded pragmatists (实用主义者).

B. Migrants had better not live in migrant centers.

C. Everyone can live with migrants to help them fit in.

D. Everyone has done their own part to help migrants.

Thomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius.“ There is no such thing as genius,” Edison said. He said that what people called genius was mostly hard work.

But Edison was a dreamer as well as a worker.. From his earliest days as a child he wondered about the secrets of nature. Nature , he often said ,is full of secrets. He tried to understand them; then , he tried to learn what could usefully be done with them.

Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.

Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “ Work,” he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.

One night in February 1962, John H. Glenn. Jr., flew over Australia. The man in the Mercury(水星) capsule(宇宙飞行容器)was alone, but friendly voices reached him by radio. On the dark land 100 miles below, he saw a sprinkling of light. They marked the city of Perth, where people had turned on their lights as a greeting to him.

In Friendship7, Glenn radioed, “ The lights show up very well. Thank for everybody for turning them on.” His capsule raced on to the east.

During his three orbits(绕……轨道而行) of the earth, Glenn could always reach one of eighteen tracking stations. Some of them were on ship at sea. Others were in the United States.

Many of the stations had been built with the help of other countries. These countries allowed Americans to bring in radio equipment and set it up. Without the help of such lands as Nigeria(尼日利亚), Zanzibar(尚巴西,坦桑尼亚领土的一部分), and Mexico, there would have been breaks in the worldwide radio network.

John H. Glenn. Jr., was the first America to orbit the earth. For his flight, the tracking network(跟踪网络) covered 60,000 route miles. Five hundred men worked in the stations along the route. Since his flight, the network has grown. Today, it covers more than 100,000 route miles and has about one hundred stations. One-third of these stations are outside of the United States.

Jason had been watching the X Games on TV. Athletes from all over the world were competing in the most amazing sports. Just then his grandmother walked into the room. “I want to be extreme. Would you really let me do that? You always worry about my safety!” said Jason.

“You will have to follow some rules,” said his grandmother. “You can only ride in the park — never on the streets. You have to promise to wear a helmet (头盔). If you hurt yourself too much, I have the right to take your skateboard away. Is it a deal?”

“You bet!” Jason was so excited that he jumped off the sofa. A week later he had a board and a helmet.

On Saturday, his grandmother dropped him off near the park. He was happy to have a grandmother who let him try new things.

Kids in the park were moving quickly up and down the ramps (坡道). They flew into the air and landed as easily as birds. When he watched the X games, Jason felt like he was doing the tricks himself. But watching these kids up close, he knew that none of it was going to be easy. He felt a little bit scared.

Very slowly he carried his board to the ramp. Taking a deep breath, he put his right foot on the board. He kicked off with his left foot. For a few seconds he glided (滑行) along, just waiting to fall. Then he came to a stop. Kicking off again, he waited for the worst to happen. Again, he stayed up. The third time he kicked, lost his balance, and fell hard on his left knee.

It hurt, but it was no big deal! Why had he been so scared? Now he felt calm because things had gone wrong, and he was fine!

Next time he kicked off harder and went fast and farther. “Excellent!” said a girl as she passed him. “Extreme!” laughed Jason to himself. “Not quite.”

The more people I meet, the more I love my dog. Every day I am reminded why I love him so much.

Three weeks before Christmas in 2008 at about 2:00 in the morning, my dog woke us up out of a sound sleep because someone was knocking at our door. He barked in front of me as if to protect me from the stranger who was knocking. My husband answered, and it was a local police officer telling us that my father-in-law had called the police because he forgot our number. My mother-in-law was suffering from a brain disease and was in the hospital. We thanked the officer and raced to the hospital. We would have taken him, but the hospital would consider him to be a dirty pet.

After visiting the hospital we drove home and hugged our dog once more. At this point it was unlikely that little dog remembered waking us up. What he did remember was that we left him alone for several hours and he missed us. He thought we missed him, too, so he greeted us at the door with his tail wagging (摇摆).

Someone tried to break in our house that summer, but, once again, our little dog saved the day. Our curtains were damaged, but no one got in. When I got home from work, I found parts of my curtains lying on the floor. We called the police and the officer said that he did a great job.

My dog is a loving sweet dog who just wants some attention. I worked with him for months and now he sits, dances, sings, shakes hands, and so much more. The best part is he looks out for me as much as I look out for him.

My husband says the dog is spoiled (宠坏的); I say he finally has a loving home.
