This is VOA. The National Cryptologic Museum is on Fort George G. Meade, a military base near Washington, DC. The method of hiding exact meanings is called coding. People have used secret codes throughout history to protect important information. The National Cryptologic Museum celebrated 60 years of cryptologic excellence in 2012. One event there marked the sixtieth anniversary of the National Security Agency. Two former NSA workers shared their memories of operating a code machine called Sigaba.
In 1940, an American woman named Genevieve Grotjan found some information being repeated in Japanese coded messages. Her discovery helped the United States understand secret Japanese diplomatic messages. After the United States understood the code, it was possible to study messages from the Japanese ambassador to Germany and to his supervisors in Japan.
Understanding these messages helped the United States prepare for a possible war in the Pacific with Japan. After the attack on Pearl Harbor, an American Naval officer named Joseph Rochefort struggled to understand the Japanese navy code. He worked on the American base at Pearl Harbor. It was early in 1942. The American naval commander in the Pacific Ocean was Chester Nimitz. His forces were much smaller than the Japanese Naval forces. And the Japanese had been winning many victories. Joseph Rochefort had worked for several months to read the secret Japanese Naval code called JN-25. If he could understand enough of the code, he would be able to give Admiral Nimitz very valuable information.
From the beginning of 1942, the Japanese code discussed a place called "AF." Joseph Rochefort felt the Japanese were planning an important battle aimed at "AF." After several weeks, he and other naval experts told Admiral Nimitz that their best idea was that the "AF" in the Japanese code was the American-held island of Midway. Admiral Nimitz said he must have more information to prepare for such an attack.
The Navy experts decided to trick Japan. They told the American military force on Midway to broadcast a false message. The message would say the island was having problems with its water-processing equipment. The message asked that fresh water be sent to the island immediately. This message was not sent in code.
Several days later, a Japanese radio broadcast in the JN-25 code said that "AF" had little water. Joseph Rochefort had the evidence he needed. "AF" was now known to be the island of Midway. He also told Admiral Nimitz the Japanese would attack Midway on June 13.The battle that followed was a huge American victory.  That victory was possible because Joseph Rochefort learned to read enough of the Japanese code to discover the meaning of the letters "AF."
One American code has never been broken. Perhaps it never will. It was used in the Pacific during World War Two. For many years the government would not discuss this secret code. Listen for a moment to this very unusual code. Then you may understand why the Japanese military forces were never able to understand any of it.
The code is in the voice of a Native American. The man you just heard is singing a simple song in the Navajo language. Very few people outside the Navajo nation are able to speak any of their very difficult language.
At the beginning of World War Two, the United States Marine Corps asked members of the Navajo tribe to train as Code Talkers.
The Cryptologic Museum says the Marine Corps Code Talkers could take a sentence in English and change it into their language in about 20 seconds. A code machine needed about 30 minutes to do the same work.
The Navajo Code Talkers took part in every battle the Marines entered in the Pacific during World War Two. The Japanese were very skilled at breaking codes. But they were never able to understand any of what they called "The Marine Code."
The Cryptologic Museum has many pieces of mechanical and electric equipment used to change words into code. It also has almost as many examples of machines used to try to change code back into useful words.
The NSA was founded__________.

A.in 1940 B.1942 C.in 1952 D.in 2012

A man sat at a metro station in Washington DC and started to play the violin; it was a cold January morning. He played six Bach pieces for about 45 minutes. During that time, since it was rush hour, 1,100 people went through the station, most of them on their way to work.
Three minutes went by, and a middle aged man noticed there was musician playing. He slowed his pace, and stopped for a few seconds, and then hurried up to meet his schedule.
A minute later, the violinist received his first dollar tip: a woman threw the money in the money box without stopping, and continued to walk.
A few minutes later, someone leaned against the wall to listen to him, but the man looked at his watch and started to walk again. Clearly he was late for work.
The one who paid the most attention was a 3-year-old boy. His mother tagged him along, hurried, but the kid stopped to look at the violinist. Finally, the mother pushed hard, and the child continued to walk, turning his head all the time. This action was repeated by several other children. All the parents, without exception, forced them to move on.
In the 45 minutes the musician played, only 6 people stopped and stayed for a while. About 20 gave him money, but continued to walk their normal pace. He collected $32. When he finished playing and silence took over, no one noticed it. No one applauded, nor was there any recognition.
No one knew this, but the violinist was Joshua Bell, one of the most talented musicians in the world. He had just played one of the most beautiful pieces ever written, on a violin worth $3.5 million dollars.
Two days before his playing in the subway, Joshua Bell sold out at a theater in Boston where the seats averaged $100.
This is a real story. Joshua Bell’s playing in the metro station was organized by the Washington Post as part of a social experiment.
The outlines were: in a common environment at an inappropriate hour: Do we enjoy beauty? Do we stop to appreciate it? Do we recognize the talent in an unexpected situation?
One of the possible conclusions from this experience could be: If we do not have a moment to stop and listen to one of the best musicians in the world playing the best music ever written, how many other things are we missing?”
Few people stopped to listen to Joshua Bell playing because______.

A.people were in a hurry
B.they were not interested in music
C.it was too cold in the subway
D.the performance was not good enough

When children stopped to look at the violinist, their parents ______.

A.would give him some money
B.would stop to enjoy the music
C.would applaud for the performance
D.would urge them to continue walking

Joshua Bell played in the metro station in order to ______.

A.make more money
B.practice his skills in playing music
C.made an advertisement for his concert
D.find out people’s reaction under such a circumstance

The purpose of the passage is to _____.

A.set us to think about our life

It’s the place where smart people make smart machines work even smarter. It’s also in the heart of sunny California, a great place to start a family and raise kids. What could be better?
But something is happening to their children. Up until the age of two they develop normally. But then everything seems to go backwards. The children become locked into their own small world, unable to communicate at all.
They call it the “curse(诅咒)of Silicon Valley,” but the medical name for the condition is autism(自闭症). It used to be thought that autism was a kind of mental illness. Now doctors are sure that it is a neurological disease transmitted genetically. It seems that the people leading the communications revolution are having children who cannot communicate at all.
But even the parents have trouble communicating. Asperger’s Syndrome is a mild version of autism. People who have it are highly intelligent and often brilliant with numbers or system but have no social skill. This very combination of symptoms makes Asperger’s sufferers into ideal computer professionals.
The Asperger’s sufferer has always been a well—known figure in popular culture. He or she was the eccentric but dedicated scholar or the strange uncle or auntie who never married. But the high numbers of such people in Silicon Valley mean that they can meet others who understand them and share their interests. And while they might not be personally attractive, they can earn truly attractive amounts of money. They can get married and have kids. Unfortunately, many of the children of two Asperger’s parents seem to be developing serious autism.
There is little anyone can do. It takes hours of work just to make autistic child realize that anyone else exists. And there is no cure in sight. Some argue that no cure should be found. “It may be that autistics are essentially different from normal people, but that these differences make them invaluable for the evolution of the human race,” says Dr. Kirk Whilhelmsen of the University of California. “To eliminate the genes for autism could be disastrous. ”
It seems that the children of Silicon Valley are paying the price of genius.
What does Dr Kirk Whilhelmsen think of autism?

A.It is disastrous to society.
B.It is not completely a bad thing.
C.It is a punishment to those working in Silicon Valley.
D.People with autism should never marry.

What can we learn about autism according to the passage?

A.It is believed to be a king of mental illness that can be cured.
B.People with autism can’t find people sharing their interests.
C.They do not care about the presence of others.
D.They are a burden for the society.

Why do people call autism “curse of Silicon Valley”?

A.Because autistic people live in Silicon Valley.
B.Because many people working in Silicon Valley have autism children.
C.Because people with autism will be driven out of Silicon Valley.
D.Because people with autism are not personally attractive and not liked by others.

What can we know about Asperger’s Syndrome according to the passage?

A.Asperger’s sufferers are ideal computer professionals.
B.Asperger’s sufferers never get married and have children.
C.Asperger’s sufferers are ashamed of themselves and locked into their own world.
D.Asperger’s sufferers can be beneficial to society if they are cured.

The popular US drama series “House of Cards”, which has already started its second season, features Chinese elements in its storyline. Traditional heroes are no longer sought after anymore. Today, it’s unconventional leading figure -like Francis J. Underwood from “House of Cards” who are winning audiences’ hearts.
The political drama, which airs on the Internet service Netflix, has won the applauses of viewers around the world since its debut(首次亮相) on February 1, 2013. And it has caught the attention of real politicians, including US President Barack Obama.
Kevin Spacey plays Francis J. Underwood, a cold-blooded Democrat who moves his way up the political ladder by any means necessary. He often uses his under-exposure in media to carry out misdeeds that will later benefit him.
The revenge(报仇) theme plays a heavy role throughout the storyline, Underwood, who had high hopes for an appointment as Secretary of State in the first season, was betrayed by the US President and his former colleagues. He and his wife then conducted a plan of revenge and swore to unseat those who turned their backs against him. Through their plan, Underwood’s own hunger for power grew and empowered him to get rid of whoever stood in his Way.
The release of the trailer(预告片) of the second season excited millions of viewers around the world, including US President Barack Obama, who has been a loyal fan since the series debuted. Obama expressed his admiration for Underwood. “This guy’s getting a lot of stuff done,” he said. Although the President is anxious to watch the story unfold, he’d like to do it at his own pace. After the release of the second season on February 14, 2014, Obama sent words on his Twitter account, “Tomorrow: @HouseOfCards. No spoilers , please.”
The second season has promised to be darker, with more unexpected turnouts, and is to include more Chinese elements. “Perhaps the team, including myself, has realized that in the next decade, Asia will be an extensively important region, and China will play an active role in its transition and change,” says Spacey.

The English test will be removed from China’s college entrance exam by 2020, according to details of exam and admission reform revealed by the Ministry of Education. The national college entrance exam, known as the “Gaokao” has been used to evaluate Chinese students for three decades. The Ministry of Education has worked out a plan for reforming exams and enrollment. The Ministry will solicit(征求) public opinions before its release. Instead, tests will be held several times a year to allow students to choose when and how often they sit the exam so as to alleviate study pressure and change China’s once-in-a-lifetime exam system.
The plan and suggestions for its implementation will be announced in the first half of next year. It will be piloted in selected provinces and cities and promoted nationwide from 2017. A new exam and admission system will be established by 2020, according to the education ministry.
The decision has aroused a heated discussion among Shanghai educators and parents who doubted the reform would reduce the burden of learning English or if the substitute test could reflect a student’s English skills and help students learn English better.
“The reform shows China is learning from the West to give students more test-taking chances. But more chances might become more of a burden since Chinese students are likely to repeat the test until they get the highest score,” said Cai Jigang, a professor at Fudan University’s College of Foreign Languages and Literature and chairman of the Shanghai Advisory Committee for College English Teaching at Tertiary Level.
Yu Lizhong, chancellor of New York University Shanghai, where classes are in English and students are required to have a high standard of English, said the most important aspect of the reform lay in what to test and how to test.
“ As far as I see, the reform doesn’t mean English is no longer important for Chinese students after it will be excluded from the unified college entrance exam,” Yu said. “In a way, English is even more important than before since the test would only serve as reference, while every college and university, even every major, can have different requirements of a student’s English skills under a diverse evaluation system. ”
Yu said some students will have their study pressure reduced if the major they choose doesn’t need excellent English while others still need to study hard if they want to be among the best students.
The education ministry said the reform would not affect students attending the college entrance exam over the next three years.
What can we learn from the first paragraph?

A.English will become less and less important in the stage of compulsory education.
B.It has been 30 years since English became one subject of national college entrance exam.
C.China’s once-in-a-lifetime exam system is unacceptable at all.
D.The system that tests are held several times does more good than once-in-a-lifetime exam system.

According to the passage, Shanghai educators and parents argue that _____.

A.the new exam and admission system will make no difference
B.English shouldn’t be removed from China’s college entrance exam
C.the reform may accomplish the very opposite
D.Western educational system does not apply to China

What does the passage try to express in the underlined sentence?

A.Students needn’t lay a good foundation during the period of high school.
B.Whether students should study hard English may depend on their major.

In December 2008, Caroline Kennedy — daughter of the late U.S. President John F. Kennedy—sat down, as a frontrunner for the Senate seat in New York, for a televised interview that helped decide the future of her campaign. The result was a disaster.
Her performance wasn’t well received, in part because her speech was full of filler words—“ums,” “ahs” and “you knows.” One listener counted 27 “ums” and 38 “you knows” in the space of five minutes. A few weeks after the interview, Kennedy ended her Senate campaign.
Filler words may seem natural in everyday speech, but they can be deadly in formal presentations. “Using excessive fillers is the most annoying speech habit,” said Susan Ward, a speech specialist. “They take your listener’s attention away often to the point that he doesn’t hear anything you say. Your message is entirely lost.”
Many speakers are afraid of pause. They believe their audience will think they are inarticulate (不善于表达) if they pause to think of what to say next, so they use filler words to avoid the silence. However, a pause is actually more impressive than a filler word. Listeners know that the speaker is thinking, trying to find the right word. Sometimes a pause can actually improve a speech, as when an actor uses a dramatic pause to hold the attention of his audience. A speaker shouldn’t be afraid to pause occasionally during a speech; it shows self-confidence.
It takes some work to cut out filler words. You can begin by taking a few seconds to think about what you want to say the next time you are asked a question. This pause will help you begin powerfully, and it will help you avoid using a filler word.
The same public speaking technique applies when you are shifting from one idea to another. While you may be tempted to fill the silence between ideas with a filler word, remember to allow yourself to pause and think about what you want to say next.
If you need help overcoming your “um” problem, consider asking a family member or a friend to point out when you use filler words. You also could record an upcoming presentation and then watch yourself in action. You may be amazed at how often you say “um” or “uh”!
Although we live in a fast-paced society that seemingly demands instant answers, we must use the pause to our advantage. Finally, we should only speak when we are ready.
In the first two paragraphs of the article the writer intends to ______.

A.introduce Caroline Kennedy to readers
B.illustrate how deadly filler words can be in the public speech
C.explain what filler words are
D.remind readers that they should count filler words used in public speeches

The reason why filler words are considered annoying by speech specialist is that ______.

A.they prevent the listener from focusing on what the speaker is saying.
B.they convey the speaker’s superiority to the listener.
C.they mean the speaker is not articulate at all.
D.they make the speaker appear self-confident.

When used properly, pauses in speeches can actually ______.

A.give the speaker more credibility
B.hold the attention of the audience
C.show the speaker’s deep insight
D.help the audience relax

Which of the following is NOT suggested as a way to get rid of filler words?

A.To have mental training in order to think faster.
B.To ask someone else to point out when you use filler words.
C.To watch a recording of your own speech.
D.To practice thinking for a moment before answering a question.
