Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gesture and by making questioning noises.

    Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can't be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation leads on to deliberate imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.

    It is a problem we need to get our teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world. Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however, whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.

    Information Overload

    One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn't have food, water, a phone, or other supplies. He was getting colder by the minute.

    Nicholas had no idea where he was. He tried not to panic(惊慌). He thought about all the survival shows he had watched on TV. It was time to put the tips he had learned to use.

    He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn't, his body temperature would get very low, which could quickly kill him.

    Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.

By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could— he huddled in his cave and slept.

    The next day, Nicholas went out to look for help, but he couldn't find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.

    Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls'survival show Man Vs. Wild. That's where he learned the tips that saved his life. In each episode of Man Vs. Wild, Grylls is abandoned in a wild area and has to find his way out.

    When Grylls heard about Nicholas'amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple—eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be the so–called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV—where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too. The researchers added, "Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start."

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, "This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful."

    If you're looking to fully experience Africa's breathtaking scenery, and have an eye for adventure, then there's only one place to be. Here, inside Africa picks four of the best hikes from across the continent.

    ⒈Kilimanjaro

    Make it to the top of Tanzania's 5,895-meter Kilimanjaro, and you'll be standing at Africa's highest point. The mountain is Africa's most-visited hiking destination, attracting tens of thousands of tourists and adventures every year.

    You don't have to a technical climber to climb Mount Kilimanjaro; you just need not be pretty physically fit. There are six routes to choose from difficulty, scenery and success. No special equipment

    ⒉Atlas mountains

    The High Atlas is an impressive mountainous range in central Morocco that hosts North Africa's highest peak. Mount Toubkal, at 4,165 meters. There's a variety of routes to follow during your climb but inexperienced climbers should note that the hike through the mountain's challenging zones is quite demanding.

    ⒊Mount Kenya

    A long-extinct volcano. Mount Kenya is Africa's second-highest peak, at 5,199 meters.

    Lying just south of the equator, the mountain's deep valleys and diverse wildlife will guarantee you wonderful scenery and a fantastic hiking experience.

    The climb, however, to the mountain's steep ice-capped peaks is quite challenging, making it the most technical, probably, in that East African area.

    ⒋Mount Meru

    Mount Meru may forever exist in the shadow of its neighbor, Kilimanjaro, but Tanzania's second-highest mountain (4,565 meters) has its own devotees.

    It's less known, but Mount Meru is for the true enthusiast who wants to experience what very few people actually do.

    Mount Meru is often used by mountaineers to accustom themselves before trying to conquer Kilimanjaro, or by those wanting a hike with the local Massai.

    Being highly successful in any field is pretty rare. It takes a combination of natural talent, luck, determination, and plenty of outside support for someone to make it big in sports, entertainment, or business. But what if competing is all that matters to you, whether you are likely to succeed or not? This was the goal of Michael Eddie the Eagle Edwards, and that he reached that goal was an amazing achievement.

    Born in the U.K. in 1963, Michael was an enthusiastic downhill skier whose dream was to compete for Britain in world-class competitions. He would have liked to represent his country in the 1984 Winter Olympics, but there were a large number of downhill competitors, and Edwards didn't qualify. Seeing his chance elsewhere, he switched to ski jumping. Ski jumping didn't cost nearly as much, and there was almost no competition for a place on the Britain team.

    But number of hurdles (障碍)could have meant the end of Edwards' dream. He weighed more than most competitors, which put him at a disadvantage. He had no financial support for his training. Poor eyesight meant that he had to wear glasses under his goggles (护目镜)- not a good thing when they steamed up at high altitudes. But he couldn't let any of this discourage him. He saw himself as a true lover of the sport who simply wanted the chance to compete. Winning wasn't the point. Having the opportunity to try was all he cared about. And nothing could stop him from trying.

    In the end, Edwards took 55th place in the 1987 World Championships. He then went on to the Calgary Olympics in 1988, where he finished last in both of his events. Many athletes would have been embarrassed by this result, but he is proud of his achievement to this day. His determination to fight against all the odds made him a global hero, and in 2016, the inspiring film Eddie the Eagle was made about his life.
