The German shepherd runs off and noses around in the grass of Kenya’s Laikipia Plateau. “OK, Oakley,” the dog’s handler orders, “Find it!”
Oakley sniffs (嗅) until he comes to a bush, then stops, sits, and looks up at his handler. She bends to see what he has found: the waste of an endangered African wild dog. “Good dog!” she praises. The handler pulls a tennis ball from her pocket. Oakley jumps for his reward.
“He doesn’t actually want the waste,” says Aimee Hurt, a founding member of the U.S.-based group Working Dogs for Conservation. Hurt is in Kenya to train both Oakley and his handler. “He finds it so he can play with his ball. We’re the ones who want the waste.”
Detection dogs are sometimes taught to locate actual animals. Black-footed ferrets (雪貂) have been studied with their help. But more often the dogs learn to locate the waste of creatures such as bears, wolves and mountain lions.
What the dogs find provides scientists with data about a species. Scientists can use the DNA collected from animal waste to identify individuals, sex, and population sizes — all without ever seeing the animal itself. “It can take years to gather this kind of information if you have to trap animals,” Hurt explains.
Waste analysis might make a huge difference when wild species are accused of attacking domestic livestock (家畜). Hurt says, “A good detection dog will find the waste so we can see what the animal is actually eating.” This may help reduce problems between people and wildlife.
The underlined word “She” in Paragraph 2 refers to  “_____”.

A.the German shepherd
B.an African wild dog
C.Aimee Hurt
D.the handler

Oakley is interested in finding the waste because _____.

A.he wants to study endangered animals
B.he can get a tennis ball to play with
C.he wants to eat it
D.he wants to play with it

Which of the following is TRUE according to the passage?

A.Trapping animals is not difficult.
B.People are making efforts to protect the environment.
C.Detection dogs attack domestic livestock frequently.
D.Collecting animal waste is a good way to gather information.

What is the main idea of the passage?

A.Detection dogs can help scientists study wildlife.
B.Detection dogs can defend wildlife.
C.Detection dogs can help the police catch the criminals.
D.Detection dogs can help local people defend domestic livestock.

Dear Malia and Sasha,
I know that you've both had a lot of fun these last two years on the campaign trail, going to picnics and parades and state fairs, eating all sorts of junk food your mother and I probably shouldn't have let you have. But I also know that it hasn't always been easy for you and Mom, and that as excited as you both are about that new puppy, it doesn't make up for all the time we've been apart. I know how much I've missed these past two years, and today I want to tell you a little more about why I decided to take our family on this journey.
When I was a young man, I thought life was all about me—about how I'd make my way in the world, become successful, and get the things I want. But then the two of you came into my world with all your curiosity and mischief and those smiles that never fail to fill my heart and light up my day. And suddenly, all my big plans for myself didn't seem so important anymore. I soon found that the greatest joy in my life was the joy I saw in yours. And I realized that my own life wouldn't count for much unless I was able to ensure that you had every opportunity for happiness and fulfillment in yours. In the end, girls, that's why I ran for President: because of what I want for you and for every child in this nation.
I want all our children to go to schools worthy of their potential—schools that challenge them, inspire them, and instill in them a sense of wonder about the world around them. I want them to have the chance to go to college—even if their parents aren't rich. And I want them to get good jobs: jobs that pay well and give them benefits like health care, jobs that let them spend time with their own kids and retire with dignity.
I want us to push the boundaries of discovery so that you'll live to see new technologies and inventions that improve our lives and make our planet cleaner and safer. And I want us to push our own human boundaries to reach beyond the divides of race and region, gender and religion that keep us from seeing the best in each other.
Sometimes we have to send our young men and women into war and other dangerous situations to protect our country—but when we do, I want to make sure that it is only for a very good reason, that we try our best to settle our differences with others peacefully, and that we do everything possible to keep our servicemen and women safe. And I want every child to understand that the blessings these brave Americans fight for are not free—that with the great privilege of being a citizen of this nation comes great responsibility.
That was the lesson your grandmother tried to teach me when I was your age, reading me the opening lines of the Declaration of Independence and telling me about the men and women who marched for equality because they believed those words put to paper two centuries ago should mean something.
She helped me understand that America is great not because it is perfect but because it can always be made better—and that the unfinished work of perfecting our union falls to each of us. It's a charge we pass on to our children, coming closer with each new generation to what we know America should be.
I hope both of you will take up that work, righting the wrongs that you see and working to give others the chances you've had. Not just because you have an obligation to give something back to this country that has given our family so much—although you do have that obligation. But because you have an obligation to yourself. Because it is only when you hitch your wagon to something larger than yourself that you will realize your true potential.
These are the things I want for you—to grow up in a world with no limits on your dreams and no achievements beyond your reach, and to grow into compassionate, committed women who will help build that world. And I want every child to have the same chances to learn and dream and grow and thrive that you girls have. That's why I've taken our family on this great adventure.
I am so proud of both of you. I love you more than you can ever know. And I am grateful every day for your patience, poise, grace, and humor as we prepare to start our new life together in the White House.
Love, Dad

Birthdays often involve surprises. But this year's surprise on the birthday of the great British playwright William Shakespeare is surely one of the most dramatic.
On April 22, one day before his 441st birthday anniversary, experts discovered that one of the most recognizable portraits of William Shakespeare is a fake. This means that we no longer have a good idea of what Shakespeare looked like. “It's very possible that many pictures of Shakespeare might be unreliable because many of them are copies of this one,” said an expert from Britain's National Portrait Gallery.
The discovery comes after four months of testing using X-rays, ultraviolet light, microphotography and paint samples. The experts from the gallery say the image —commonly known as the “Flower portrait”— was actually painted in the 1800s, about two centuries after Shakespeare's death. The art experts who work at the gallery say they also used modern chemistry technology to check the paint on the picture. These checks found traces of paint dating from about 1814. Shakespeare died in 1616, and the date that appears on the portrait is 1609.
“We now think the portrait dates back to around 1818 to 1840. This was when there was a renewed interest in Shakespeare's plays,” Tarnya Cooper, the gallery's curator (馆长), told the Associated President.
The fake picture has often been used as a cover for collections of his plays. It is called the Flower portrait because one of its owners, Desmond Flower, gave it to the Royal Shakespeare Company.
“There have always been questions about the painting,” said David Howells, curator for the Royal Shakespeare Company. “Now we know the truth, we can put the image in its proper place in the history of Shakespearean portraiture.”
Two other images of Shakespeare, are also being studied as part of the investigation and the results will come out later this month.________.
What makes the birthday of Shakespeare dramatic this year?

A.It was found that he painted a portrait in 1814 instead of in 1609.
B.The Flower portrait has been found to be a fake.
C.Three portraits of Shakespeare are being tested to identify a real one.
D.It was found that there was a renewed interest in Shakespeare's plays around 1818 to 1840.

Which statement is True according to the passage?

A.Portraits of Shakespeare are all unreliable.
B.“Flower portrait” was a portrait of Shakespeare given to Desmond Flower.
C.1814 might be when the portrait was drawn.
D.The Flower portrait is not often used as a cover for Shakespeare's play.

How many methods were used to test the portrait?

A.Not mentioned. B.Two
C.Three D.At least four.

The best title for this passage is ________.

A.Birthdays often involve surprises
B.The surprise on the 441st birthday of Shakespeare

Which is the best sentence to fill in the blank in the last paragraph?

A.Soon we'll know which portrait is reliable.
B.Maybe we cannot find a real portrait of Shakespeare.
C.If the two portraits are found to be false, they will test more.
D.For now what Shakespeare really looked like will remain a mystery.

The Hunan Satellite TV(HNTV) show “Where are we going, Dad?” is a big hit. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the “how to be a good father”. As the young parents today are too busy to take care of their children, this new form of “Lost on the way” played by nanny Daddy and cute kids triggered(触发)a lot of people’s emotional resonance(共鸣). Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.
The TV shows like “Children are hard to support!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becoming more and more popular. All of these show the new parents’ confusion in children’s education and the appeal for the balance between career and family.
In real life, on the one hand the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand they continue to do so. The data collected by HNTV shows that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34.We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. The participation of mother in the children’s education is also very low.
It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that “Where are we going,Dad?” shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go.
In raising a child in modern society, parents should ________.

A.play computer games with their children
B.keep their children at home to avoid socializing
C.balance well between family and career
D.break down the barrier between children and teachers

Which of the following can be inferred in the passage?

A.Parents shouldn’t entirely leave the education of children to the old.
B.36% of the audience of the program are female aged from 25-34.
C.The program shows us the confusion where the parents and children will go to play.
D.In a modern family it is often mothers who are responsible for raising a child.

Which one is the best title of the passage?

A.Confusion Behind “Where are we going, dad?”
B.Modern Education is Important
C.Nanny Daddy and Cute Kids
D.New problems in Modern Children’s Education

What attitude towards modern family education does the author express in the second paragraph?

A.Proud. B.Worried.
C.Optimistic. D.Indifferent.

Here are a few tips to help you, the workaholic, re-focus and get the best out of life.
EIGHT HOURS OF SLEEP! Make it a point to get at least eight hours of sleep and plenty of rest. Don't believe that you can always "catch some sleep or rest later." Your body cannot make up for lost sleep or rest time because it is not physiologically possible.
STRICTLY FAMILY ON WEEKENDS! Resolve to make Saturdays and Sundays strictly for family time. And stick to this! Mondays until Fridays you make an excuse not to relax and spend time with your family because it's work time, why not make a similar excuse for Saturdays and Sundays? "I can't work today because I'm spending time with my family."
GET SOME FOOD IN! Make sure you get food in your stomach. Workaholics are known to be food-skippers. If you can't afford to get off your desk or from doing paperwork, have food delivered to you. It's always a good idea if you have crackers on your drawer to ease the hunger pangs.
CONFINE WORK! Resolve to confine work in your office. Don't bring work to your home! Keep those files in your office desk where they belong. Practice working only within your working hours. If you have an eight-to-five working schedule, stick to it.
WORK UP THOSE MUSCLES! Exercise, exercise, exercise! Set aside at least an hour each day or every other day for exercise. You body needs to be conditioned, and working non-stop isn't going to give it the proper physical conditioning it needs. Since most workaholics tend to have their behinds stuck on their chairs, it's even more important that you get some exercise.
MAKE A PLAN! Plan your day. Work on only one or two things at a time. It's much easier to work on something and finish it first and then move on to the next rather than do a number of things all at the same time and never finish or accomplish anything at the end of the day. Make out a list of priorities. Write down things that need to be worked on immediately or are urgent, keeping the least ones at the bottom of your list. After you've done this, be guided by this list. Turning this activity into a habit will also help you manage your time better, be more organized, and accomplish more.

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

According to the passage, which one is not right?

A.“Cryptologic” implies containing some hidden information
B.The US decoded “AF” and won the victory in Midway Islands
C.Both Rchefort and Nimitz were American navy commanders
D.The US Marine Corps was fallen for in Midway Islands battle

A. unusual language was successfully used for codes
B.it was commonly used in coding system worldwide
C.the United States Marine Corps invented it then
D.it was the most beautiful language in the world

This passage is probably adapted from ____________.
