1 . Humans are not the only ones who underwent self-domestication. So did our close relatives, the bonobos, and the species we call our best friend. A tiny proportion of the genome differentiates dogs from wolves, and yet millions of dogs are comfortably curled up in our homes, while wolves move around at the edge of extinction.
When our research group began its work almost 20 years ago, we discovered that dogs also have extraordinary intelligence: they can read our gestures better than any other species. Wolves, in contrast, are mysterious and unpredictable. Their home is the wilderness, and that wilderness is shrinking.
But not so long ago the evolutionary race between dogs and wolves was so close, it was unclear who would win. Dogs, in fact, did not descend from wolves. Instead, dogs and wolves shared a wolflike ancestor.
Folklore supposes that humans brought wolf puppies into camp and domesticated them. Or as wolf expert David Mech wrote in 1974, “Evidently early humans tamed wolves and domesticated them, eventually selectively breeding them and finally developing the domestic dog from them.” But this story has not held up. Taming an animal occurs during its lifetime. Domestication happens over generations and involves changes to the genome.
So how did wolves turn into dogs? Back in the Ice Age, as our human populations grew more sedentary, we probably created more rubbish, which we then dumped outside our camps. These leavings would have included tempting pieces of food for hungry wolves. Not every wolf would have been able to scavenge, however. These animals would have had to be unafraid of humans, and if they displayed any aggression toward us, they would have been killed. After generations of selection for friendliness without intentional selection by humans, this special population of wolves would have begun to take on a different appearance. Coat color, ears, tails: all probably started to change.
Animals that could respond to our gestures and voices would be extremely useful as hunting partners and guards. They would have been valuable as well for their warmth and companionship, and slowly we would have allowed them to move from outside our camps to our firesides. We did not domesticate dogs. The friendliest wolves domesticated themselves.

2 . A 15-year-old Indian girl, Kumari, who pedalled her injured father more than a thousand kilometres across India, has been invited to try out for the national cycling team.
In January, a motor-bike driver, Mohan Paswan, who made a living by carrying passengers in New Delhi, was injured in a traffic accident. After the accident, Paswan couldn't drive. So his daughter, Kumari took a train across the country to take care of him. But without income, Paswan could no longer afford the rent and they were running out of food. They decided to go home. With the last $20, the 15-year-old girl bought an old bicycle, and planned to take her father to their home village across India --- in a heroic, life-saving ride.
Kumari rode a bicycle with her father, sitting on the pillion(后座)and holding their belongings from Gurugram city, near New Delhi, to their village in the northeastern state of Bihar. They arrived home on May 16 after covering 1,200 kilometres (745 miles) in seven days.
The father and daughter's arduous journey on a second-hand bike bought with their remaining funds made headlines. It also caught the attention of the Cycling Federation of India, which offered Kumari the chance to try out for the country's team. "She covered this long and difficult distance in seven days with her father and some luggage too. I thought she has something in her endurance level. We can try her," chairman Onkar Singh told the journalist.
“She said she only wants to pursue her studies. We told her that we also take care of studies at our academies. Singh said the federation would test Kumari to see if she is suitable for competitive cycling.
There were also other people who praised Kumari's efforts, describing it as a "'beautiful model of endurance and love."

3 . Social Networking Sites: Are They Changing Human Communication?
It is hardly news that people are using the Internet to communicate with others more and more. Some people fear that someday we will no longer feel the need to talk to one another face to face. However, some recent studies suggest that people communicate, or stay in touch, even more than they used to. Whichever side you fall on, what is clear and without a doubt is that human communication has changed in the 21st century. But results of recent scientific studies may have us reconsider just how much our new communication forms have changed our world.
In June 2008, a British psychiatrist, Himanshu Tyagi, warned that communicating on social networking sites could have a negative effect on the generation of people born after 1990. This generation has never known a world without the Internet. Tyagi says that these people use the Internet to communicate with others so much that they may have trouble forming real relationships. Tyagi is concerned that people may start and end relationships over the Internet. Describing the Internet he said, “It’s a world where everything moves fast and changes all the time, where relationships are quickly ended at the click of a mouse.”
Another psychologist, Dr. Aric Sigman, warned of the physical effects that come with using social networking sites. He suggests that the reduction in the amount of time we spend interacting (互动交流) with people face to face could have biological effects on the human body. The results of his study suggest that, without real personal interaction, the body does not react the same way it would if people were meeting face to face. As a result, immune responses, even hormone levels, can be changed. These changes may lead to the development of illnesses, such as cancer.
Despite these warnings, studies can be found that show the positive sides of social networking sites. The results of one study show that using social networking sites has increased the self-esteem (自尊心) of young adults. Another suggests that college students using these sites feel more “connected” with people when they use them. In addition to scientific studies, there are many who feel that the benefits of social networking sites outweigh the possible negative sides. Many people, especially those who spend a lot of time at home, for various reasons, find the Internet a lifeline. They are able to communicate with many people using these sites.
Perhaps the key to this new communication style is self-control and common sense. If someone spends all of his time on the Internet, and never actually sees friends face to face, that seems like an unhealthy way to live. But if someone spends time on the Internet, some of which is spent arranging meetings for “real” time together, then it seems almost complementary (互补的). Balance is the key to keeping communication alive and well in the 21st century.
1. Which of the following ideas may Himanshu Tyagi agree with?| A．Social networking sites harm people of all ages. |
| B．The Internet weakens young people’s relationships. |
| C．The use of the Internet improves people’s immune system. |
| D．The online world pushes people to live a faster and better life. |
| A．It will stop the face-to-face interaction. |
| B．It reduces the self-esteem of young adults. |
| C．It may cause some serious health problems. |
| D．It makes people feel less connected with others. |
| A．Are greater than. | B．Are heavier than. |
| C．Are more effective than. | D．Are more difficult than. |

4 . An elephant and a crocodile were once standing beside river. They were disputing which was the better animal.
“Look at my strength,” said the elephant. “I can pull up a tree, roots and all with my trunk”
“Ah! But your skin is not nearly so thick as mine,” replied the crocodile. “No knife or tooth can cut through it.”
Just as they were coming to blows, a lion happened to pass.
“My dear friends!” said the King of all animals, going up to them. “Let me know the cause of your disagreement.”
“Will you kindly tell us which is the better animal?” cried both at once.
“Certainly”, said the lion, pointing across the river. “Do you see the soldiers’ metal hat on that wall?”
“Yes!” replied the beasts.
“Well, then,” continued the lion, “go and get it, and bring it to me, and I shall be able then to decide between you.”
Upon hearing this, off they started. The crocodile, being used to the water, reached the opposite side of the river first, and was soon standing beside the wall.
Here he waited till the elephant came up. The elephant, seeing that the crocodile had no way of reaching their goal, raised his long trunk, and took down the hat quite easily.
They then made their way together back again across the river. The elephant was trying to keep up with the fast-moving crocodile in the water and became careless. When he was forced to turn sharply to avoid a floating tree branch, the elephant dropped the hat and it fell to the river bottom. The crocodile noticed the accident, so down he dived, and brought it up in his huge mouth. They then returned, and the crocodile laid the metal hat at the lion's feet. The King took it up, and turning to the elephant, said: “You, because of your size and trunk, were able to reach the hat on the wall but, having lost it, you were unable to get it back. And you,” said the lion to the crocodile, “although unable to reach the hat, were able to dive for it and save it. You are both wise and able in your own ways. One is no better than the other.”

5 . All Ric O Barry wants is to stop the dolphin-killing, so he is headed to this seaside Japanese town, Taiji. The American activist, who is the star of a new award-winning documentary that portrays the dolphin-killing here, got an unwelcome reception when he showed up here this week for the start of the annual hunt.
His movie, The Cove (海豚湾 ), directed by National Geographic photographer Louie Psihoyos, was released in the United States a month ago but has not yet to come out in Japan.
Scenes in the film, some of which were shot secretly, show fishermen banging on metal poles stuck in the water to create a wall of sound that scares the dolphins — which have supersensitive sonar (声呐系统) — and sends them fleeing into a cove.
There, the fishermen sometimes pick a few to be sold for aquarium shows, for as much as $150, 000. They kill the others, spearing the animals repeatedly until the water turns red. The meat from one dolphin is worth about 50, 000 yen, and is sold at supermarkets across Japan.
Greenpeace and other groups have tried to stop the hunt for years. Activists hope The Cove will bring the issue to more people internationally—and eventually in Japan.
Already, the Australian town of Broome dropped its 28-year sister-city relationship with Taiji last month, partly because of the movie.
“Some regions have a tradition of eating dolphin meat,” said fisheries official Toshinori Uoya. “Dolphin-killing may be negative for our international image, but it is not something orders can stop.”
The town government in Taiji — which has made whales and dolphins its trademark — refused to comment about The Cove, or the growing international criticism against dolphin-killing.
Many in Taiji take the dolphin hunt for granted as part of everyday life. They are defensive about The Cove, seeing themselves as powerless victims of overseas pressure to end a simple and honest way of making a living.

6 . It was late one evening. I can’t remember what it was about, but my Dad and I had a very big argument when my mother was away. We both said things we didn’t mean, and in the end I said, “I’m leaving.” And he said, “Good. The sooner, the better.”
I threw a few things in the suitcase and closed the door violently behind me, not knowing where I was going. After walking aimlessly for 20 minutes, I stopped at a local supermarket. Then my phone rang. It was my mom calling. She said, “Hey, Mary. Where are you? Dad is worried about you.”
“How can he worry about me? I’ve been away for nearly half an hour, but he didn’t call.” I said with annoyance. My anger returned and I remembered all the hateful things he’d shouted to me. “Listen, Mom. You can tell Dad that I’m fine. I’ll call you tomorrow.” I said and hung up.
I walked around the supermarket, trying to get my thoughts together. By the time I paid for my purchases, it had been much later than I used to be out alone. When I left the supermarket, a large piece of white paper was in front of me. On the piece of white paper were these words: “Please come home! I miss you and I’m worried about you!”
Then a car pulled up beside me. Hanging out of the window was my Dad. Besides him, smiling gently, sat my mom. And that’s when I started laughing. I laughed so hard that I cried. Despite(尽管) my best effort to run away from home, my father finally managed to track me down. I couldn’t leave now, not with him sitting there with caring eyes.

7 . One of the most inspiring quotes I ever heard was by Brian Tracy. He said: “The difference between successful people and unsuccessful people is that successful people fail many more times than unsuccessful people.” I personally experienced the wisdom of that understanding right after my first book was published. Like many authors，I expected hundreds of bookstore customers lining up for me to sign copies for them. I’m afraid to say, it didn’t quite happen like that.
My first signing was arranged at the largest bookstore in the city. Filled with anticipation，I was put into a private signing room in the beautiful store. Despite a nice sign placed outside the room exhibiting images of both me and my book, not a single customer entered the room. As each minute passed, I became increasingly anxious.
Do they not like the title? I wondered. Do they not like the book cover?
After 90 minutes of this torture, I was absolutely distraught.
For the four years writing the book, I had felt a sense of mission and purpose like never before in my life. Working a full 8-hour day in my clinic, I had to get into bed by 9:30 pm every day, so I could wake up at 5:30 in the morning and have two hours of writing before heading into my clinic. Before I ever began each writing session, I would close my eyes for 10 minutes and then whisper, “Please grant me the words to touch just one person’s life”
Now, sitting there alone at my first book signing，I wondered if my entire life wasn’t just a big joke. At that moment, just when I couldn’t feel any worse, a middle-aged couple walked into the room. I managed to hide my emotions and introduced myself and my book. There was something different about the way they were looking at me that I couldn’t quite identify. But I didn’t know what else to say. The couple turned to each other, and the husband nodded to his wife. She then told me, “I think we’ll get the book.” My heart began to pound. But I realized the woman was trying to say something else.
“The reason we’re buying it，” she said hesitantly, “is because our son committed suicide two years ago. Maybe your story will help us get over it.”
At that moment, I knew if I never sold another copy of the book, my four years of writing it had served its purpose. Although I would have many more challenging years until my book caught on and sold well, this couple’s story was all the motivation I needed at that point to keep me moving ahead. Thanks to them, I would come to the realization that the greatest of lives are made all in the same way: One challenge... one hurdle... one step... and one small victory at a time.

8 . I received a private message on Facebook. It began harmlessly enough: “Hey, girl. Wanted to invite you to join my next challenge group—we’ll be focusing on fitting in 30 minutes of exercise and balanced nutrition.”
It was all becoming too much. Facebook was running my life, not me.
But what killed Facebook for me was when I posted a photo, and five minutes later my son asked me how many “likes” it had got. His question was a wake-up call.
“Likes” are signs of acceptance and approval. I had forgotten that acceptance and approval need to come from within and had unknowingly set him a bad example.
Before Facebook, surfing the internet was an occasional distraction and I spent a lot more time reading books and magazines. I checked in with friends through texts, emails and phone calls.
To recreate the simplicity of those days and set a healthier example to my son, I deactivated my Facebook account.
I’d been in the habit of checking Facebook many times a day, so I had to come up with some new habits. I carried a novel and a crossword puzzle book around with me. I rediscovered knitting. I started taking yoga classes.
I started to remember a few things. My body is fine just the way it is. I have friends who will help me out when I’m in trouble, and I will help them out. I do my best to be a good mother, and our son is happy and healthy. We are very lucky to be able to afford two vacations a year.
I stopped looking at the world through my cellphone. I felt completely present in the moment.
The break left me feeling better about myself, my family, my home and my life.
After a few weeks, I returned to Facebook. Now I look at the photos of my friends’ kids growing up and treasure how social media allows me to keep in touch with family far and wide. I look in on a daily basis, but no longer with the desire constantly to post updates.
It is not an addiction any more.

9 . Kevin, diagnosed with Dyslexia(读写困难症), rarely spoke a word in class, and if he did, it would be a “ Yes,” “No,” or “Maybe,” in response to questions. He always scored badly in tests and saw no hope for the future. That was until he met Sarah, an advisor at a youth centre Kidpreneur.
In 2012, Kevin attended a course called Ready Set Go in that centre. The course was for disadvantaged kids in Kingswood – a low – income area in Sydney’s western suburbs – and its goal was to teach the kids how to create businesses and offer value to the neighborhood.
At the end of the course, Sarah took the kids to the local area. She asked volunteers to share their business experiences – Kevin immediately put up his hand. His challenge was to trade his hot – dog selling service for free bread at a bakery. Although scared, Kevin was able to share his entrepreneur(创业) story with the shop owner and asked if he could exchange his service for some bread. Unexpectedly, the shop owner told Kevin how moved he was by his story and handed him some bread for free. By the end of the afternoon, his belief in himself and what was possible was at an all- time high.
The following week, Kevin sold 70 hot – dogs in two hours and made over $200. Soon after, he delivered public speeches in 20 schools, and was selected as part of his school’s leadership team. Now he heads a business group working on how to increase potential customer base.
All of his would not have been possible if Kevin had not found his passion and perseverance to improve himself, and those around him. The guidance and trust of his advisor also helped to kindle his enthusiasm to go after his goals and dreams in life.

10 . It is a question that has long puzzled scientists—exactly why are tigers orange? One might think it makes them more obvious-particularly against a leafy green forest background. William Blake summed it up in his famous poem known by generations of schoolchildren: “Tyger, tyger, burning bright / In the forest of the night.” But now the answer is at hand.
While obvious to us, computer simulations (模拟) of what the big cats look to the main animals they hunt for, deer, show a different picture. Humans with normal colour vision, can see red, blue and green colours. But deer can only pick up blue and green light, they are effectively colourblind to the colour red, like some humans. It means the tigers’ orange colouration looks green to them, allowing them to mix perfectly into the background, new research claims.
Dr John Fennell at the University of Bristol and colleagues said that they used computers to estimate how noticeable a given animal was. They did this by using images of the environment in which the animal lives, and then creating images to see whether the camouflage helps the animal to mix in.
Dr Fennell writes that by simulating what the world looks like to animals who are “two-colour vision”—someone who cannot discover the difference between red and green—“we also identify the most suitable colours for hiding and visibility”.
Dr Fennell writes in the Royal Society Journal Inter face: “Considering the coat of a tiger, it has fur that appears orange to a three-colour vision observer rather than some shade of green, though the latter should be more appropriate color for an attack hunter in forests. However, when viewed as a two-colour vision observer, the tiger’s colour is very effective.”
The question then arises as to why tigers don’t grow green coats. Dr Fennell and colleagues write that mammals (哺乳动物) are not able to produce green fur. To do so would “require a significant change to mammalian biochemistry”. There is only one mammal known to have green fur but this is achieved through what might be considered as, well, cheating, not exactly real.

| D．The way of hunting for something. |
| A．The colour of tigers sometimes cheats people. |
| B．Getting green may prevent tigers from being extinct. |
| C．There are no mammals with real green fur in the world. |
| D．The tigers’ fur will probably evolve into green in the future. |
