Do you sometimes argue about what seems to you to be a simple fact? Do you argue whether it's cold outdoors or whether the car in front of you is going faster than the speed limit (限速)?

    If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant's trunk (象鼻) said it was like a snake. The second who felt the elephant's side said it was like a wall, while the third said it was like a spear( 矛 ) as he touched the animal's tusk. The fourth, who took hold of the elephant's tail insisted that it was like a rope. The fifth man said it looked liked a tree as he put his arms around one of the elephant's legs. The last, who was tall and got hold of the elephant's ears, said it was like a huge fan.

    Each man's idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it's often because his experience in the matter is different from yours.

    To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water (温水)in the third. Now put your left hand in the hot water. Put your right hand in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it is hot.

    After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

    Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

    The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf – grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park's red foxes, and completely drove away the park's beavers.

    As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

    The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone .Elk, deer, and coyote populations are down, while beavers and red fores have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

    The news of Harper Lee's second novel broke the internet. Go Set a Watchman would be published in July. Lee became a recluse (隐士)after the publication of her first book, To Kill a Mockingbird, in 1960. Although the author has been out of the public eye for more than 50 years, the wave that followed the announcement showed her novel's beloved place in the American literary works.

    In 1991, The Book of the Month Club and the library of Congress conducted a survey that made readers identify books that had made a difference in their lives. Lee's book followed only The Bible. Alongside the works of Shakespeare and Twain, To Kill a Mockingbird remains one of the most widely taught books nationwide, reaching an estimated 70% of American public schools. What makes it such a perfect read for young people?

    English class is a place where young Americans come to know themselves. In the folds of dusty books, students can make contact with humanity beyond the superficial(肤浅的) conversations of the school hallways. Literature promises relief, a place to figure out one's problems and get to know oneself better.

    To Kill a Mockingbird particularly distinguishes itself in this regard. It speaks in child's voice without treating its readership as children. People have called it an 'impossible' achievement, a children's book penned in the prose(散文) of a well-educated adult—it's unlikely that a child like Scout could exist in the real world. But that's exactly what makes it such a charming read for young people. It alludes to (转弯抹角地说到)the consciousness of a well-educated adult going through difficult realities, but shows it through the light and playful voice of a curious little girl.

    Why YOUR keyless car could be gone in 23 seconds: It's a crime wave reaching high proportions and the gadgets(小装置) used to hack into your car and steal it are being sold to thieves by High Street locksmiths.

    Car thieves are using high-tech gadgets to break into and steal cars in seconds. One thief stands by a house to pick up a signal from a car key using a relay. The relay broadcasts the signal to the car, where a second thief opens the door. The scheme, which does not involve breaking windows, steals cars in seconds.

    Thousands of cars across Britain are at risk of a new form of high-tech theft which allows thieves to fool bypass the security systems in keyless cars using a relay system to boost the signal. So-called 'relay' theft occurs when two thieves work together to break into keyless cars. They use equipment to capture electro-magnetic signals emitted by key fobs. Any vehicle with keyless entry could be easily stolen. These include cars from BMW, Ford, Audi, Land Rover, Volkswagen and Mercedes.

Brazil sports are out of control! Brazil may be one of the most sports­crazy countries in the world. Whether you are into watching or playing, Brazil sports have a lot to offer everyone.

Football in Brazil is more than a sport. It's a way of life. Football is popular in Brazil for several reasons. One reason is that it is fast paced and fun to watch. This is the reason why the World Cup Soccer is the most watched sports event in the world aside from the Summer Olympics. Also, you don't need anything to play soccer except for something to kick, and a big area in which to play. Few will argue if you say that Brazil leads the world in football. No nation has won as many world cups as Brazil.

Volleyball is a close second in Brazil sports. In the world of international volleyball, Brazil wins many championships of all kinds, including indoor and beach volleyball. Brazil has nearly 5,000 miles of coastline. If you go to a beach in Brazil, there will always be a volleyball game going on somewhere, and usually two or three.

Footvolley was created in Brazil in the 1960s. It is a mix of football and volleyball, where the players must use their feet and head to get the ball over the net and into the opponents' court, and is also played in sand. It is one of the most popular beach sports in Brazil.

Swimming, tennis, rugby, boxing, judo, sailing, golf, surfing, and handball are all greatly popular in Brazil.

We all know someone who holds court wherever they find themselves with amusing stories. For the rest of us, conversation can be trickier. Our editor asked Catherine Blyth, the author of The Art of Conversation for her tips on how to shine — and not get cancelled — at your next small-talk.

Consider what you want from a conversation

{#blank#}1{#/blank#}. In fact, a conversation is usually a way to get something we want, whether that's to making a friend, or to asking someone on a date. Knowing what you want will keep things flowing. "At least, what you can get from a conversation is an interesting adventure with another mind. {#blank#}2{#/blank#}." says Blyth.

Guide the other person to help you

"There's nothing more flattering (受宠若惊) than feeling like that you've helped someone," Blyth says. She suggests finding a way to make the other person useful to you. "{#blank#}3{#/blank#}, that allows you to reveal a bit of yourself while inviting them to help, which is a great way to get conversation started."

Listen attentively and purposefully

Are you listening to understand, or listening to respond? That's a perfect question a would-be conversationalist should ask themselves. "A good listener indicates what interests them. {#blank#}4{#/blank#}. If I'm conversing with someone who makes it all about themselves, I'll gently point that I'm not interested and shift us towards other topics." says Blyth.

Keep your phone out of sight and out of mind

"If you're chatting with someone with your phone next to you, what you're saying is ‘you're only as important as my next notification'," says Blyth. "Whatever you do on a screen isn't a conversation. Problems arises from comparing real conversation to text messaging. {#blank#}5{#/blank#}. We need to give each other some grace."

A. Seeing the world through the eyes of others is a reward itself

B. People feel bad about conversation because they think it's a performance

C. Your responses should show which topics are interesting and which aren't

D. The best mindset you bring to small-talk is the idea that it's a treasure hunt

E. A direct praise is good, but if it's something like ‘I love that coat, where did you buy it?'

F. In a real conversation, you can't look things up, think about how to phrase your thoughts

G. You have to constantly be listening with your ears, your mind, and be conscious of doing so
