Jumping off random cliffs(悬崖) into the sea is not clever. However, as a sport, coasteering uses local experts to help groups travel around the coast so they can then jump safely and have a lot of fun in the process. But coasteering is also so much more than cliff jumping.

    A usual day's coasteering will involve swimming, climbing, scrambling(攀岩) and cliff jumping. All trips begin with a safety brief and equipment check. You will be equipped with a helmet, wetsuit and life vest. You will need to wear some old sneakers you don't mind getting wet.

    From here it could be a short swim to the first jump site. Following an instructor, you swim through rock pools, around rough rocks and right up to the next jump spot. A brief climb and you'll be standing on the edge wondering, “Why the hell did I agree to this?” Then, and to the yell of your friends, you're leaping in, with a smile that's guaranteed to last the rest of the day.

    Coasteering is certainly more than cliff jumping. If ever a sport could claim to be confidence building, this is it. And it's also a perfect activity for groups of friends or for adventurous families who want to explore the coast. Many companies offer daily trips, so even if you are on your own or a couple you can join in with a large group. Companies use trained guides with much knowledge of local tides and weather conditions. These people lead the show and are qualified lifesavers as well.

    Coasteering is already popular around the UK. At least now you won't have to ask “What is coasteering?” if someone you know gives it a go.

    In Korea, it is rude to wear shoes inside someone's house because it is considered dirty. In Saudi Arabia, you should not bring food to someone's house because taking food or drink suggests that you think the host cannot afford the meal. More and more people around the world are travelling abroad to study, to go on vacation, or to work, and while it can be a great way to learn about other cultures, there may be times when travelers accidentally annoy their host.

    The same gesture can have very different meanings in different countries. The gesture meaning OK in the United States means something completely different in Brazil as Ella Yao discovered. Ella had travelled to Brazil to study and was living with a host family. During dinner, her host asked Ella if she was enjoying the meal. Because her mouth was full of food, Ella made a sign with her hand that to her meant OK. Although Ella meant the food was good, this symbol in Brazilian culture is extremely rude and her host was deeply annoyed.

    While travelling in Thailand, Elizabeth Brown learned that there are differences in food in the United States and Thailand. She stopped at a small, family-owned restaurant in Chiang Mai and ordered spring rolls. She was really enjoying eating them until she got the last one and noticed that there was an insect inside. She complained to the server. Later, she discovered that although insects are disgusting to most Americans, they are considered a delicacy(佳肴) in some countries.

    All these mistakes can be avoided with some research on cultural differences before you go abroad. However, if you do accidentally annoy someone, quickly apologize, and learn from your mistake.

    People who have lost the ability to understand or use words due to brain damage are called aphasics（失语症患者）.Such patients can be extremely good at something else.From the changing expressions on speakers' faces and the tones of their voices,they can tell lies from truths.

    Doctors studying the human brain have given a number of examples of this amazing power of aphasics.Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.

    Recently,scientists carried out tests to see if all that was said about aphasics was true.They studied a mixed group of people.Some were normal;others were aphasics.It was proved that the aphasics were far ahead of the normal people in recognizing false speeches—in most cases,the normal people were fooled by words,but the aphasics were not.

    Some years ago,Dr.Oliver Sacks wrote in his book about his experiences with aphasics.He mentioned a particular case in a hospital.Some aphasics were watching the president giving a speech on TV.Since the president had been an actor earlier,making a good speech was no problem for him.He was trying to put his feelings into every word of his speech.

    But his way of speaking had the opposite effect on the patients.They didn't seem to believe him.Instead,they burst into laughter.The aphasics knew that the president did not mean a word of what he was saying.He was lying!

    Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words.However,according to Dr.Sacks,they are more gifted than normal people.Normal people may get carried away by words.Aphasics seem to understand human expressions better,though they cannot understand words.

    Disease, poverty, hate, love — Charles Dickens' stories opened his readers' eyes to the most important themes of his age. Two hundred years later, his stories still speak volumes across the world, proving that Dickens' legacy (遗产) was far greater than just "great-literature".

    February 7 marks the 200th anniversary of the writer's birthday. To mark this date, BBC writer Alex Hudson listed six things Dickens gave the modern world. Let's take a look at two of them.

    A White Christmas

    Dickens is described as "the man who invented Christmas"— not the religious festival, but the cultural aspects that we associate with the festive season today.

    In the early 19th century, Christmas was barely worth mentioning, according to critic and writer Leigh Hunt. The committee which ran the Conservative Party even held ordinary business meetings on Christmas Day — unthinkable in the West nowadays, when everyone but the most necessary workers takes at least three days off.

    Many people believe that Dickens' popular descriptions of the festive period became a blueprint for generations to come. In his classic novel, A Christmas Carol, he not only put forward the idea of snow at Christmas, but also painted a picture of glowing warmth —“home enjoyments, affections and hopes".

    In his biography of Dickens, Peter Ackroyd wrote:" Dickens can be said to have almost single-handedly created the modern idea of Christmas."

    "Dickensian" poverty

    Dickens was one of the first to take an honest look at the underclass and the poor of Victorian London.

    He helped popularize the term "red tape" to describe situations where people in power use needless amounts of bureaucracy (官僚作风) in a way that particularly hurts the weaker and poorer members of society.

    "Dickensian" has now become a powerful word for describing an unacceptable level of poverty. In 2009, when the president of the Association of Teachers and Lecturers in the UK wanted to talk about poverty in some areas of Britain, she did not use words like "terrible" or "horrific", but rather described it as "life mirroring the times of Dickens".

    Earlier this month, two rock climbers achieved what many thought impossible: They climbed up the 3,000-foot-high Dawn Wall in Yosemite National Park without specialized equipment. Climbing without this equipment is called "free-climbing." Until now, no one had free-climbed to the top of the rock face, which is a part of the mountain EI Capitan.

    EI Capitan, which means "the captain" or "the chief" in Spanish, has always presented a challenge to climbers. But the Dawn Wall, on the mountain^'s southeast face, is a particularly difficult route to the summit (顶峰). It is a rock formation that is both steep and relatively smooth. This makes free-climbing the rock face seem almost impossible.

    About seven years ago, professional climber Tommy Caldwell spotted a possible route up the wall. It took years of planning and preparation, but this month, Caldwell, 36, and his friend Kevin Jorgeson, 30, finally make the climb.

    Free climbers do use ropes and other basic safety equipment to catch them if they fall — and Caldwell and Jorgeson fell often. Before starting their climb, they broke down their route into 32 sections. Each section was based on a rope length called a "pitch." The rope was secured into the rock face to catch the climbers if they fell.

    Caldwell and Jorgeson's goal was to climb the Dawn Wall without returning to the ground. If they fell, they had to start that pitch all over again. The two men started climbing on December 27. They slept in hanging tents, and a team of friends brought them food each day.

    The men had spent years rehearsing (排练) the movements it would take to get through each pitch. They made it through the first half of the climb relatively easily. But halfway up, Jorgeson ran into trouble. In one difficult spot, he fell each time he attempted to climb. After 10 days of trying, Jorgeson finally made it to the next pitch.

    Getting through that troublesome pitch gave both climbers renewed energy. They finished the rest of the climb five days later, on January 14.
