China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities.

    First, you must be punctual (准时的) with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late!

    It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surpri if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have “dress down Friday”, when people wear casual (随便的) clothes.

    In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names.

    In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive（肯定的） things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business!

    So, use these tips, and you will be on your way to a successful international business career!

    Buck's first day in the frozen Northland was like a bad dream. Every hour was filled with shock and surprise. Here was neither peace, nor rest, nor a moment's safety—only continual noise and movement. At evey moment life itself was in danger, because these dogs and men were not town dogs and men. They knew only the law of club and tooth.

    He had never seen dogs fight as these wolfish creatures fought, and his first experience taught him an unforgettable lesson. Curly was the victim(牺牲者). She tried to make friends with a Husky, a dog only half as large as she was. There was no warning. The dog jumped on Curly, his teeth closed together, then he jumped away, and Curly's face was torn open from eye to mouth.

    Wolves fight like this, biting and jumping away, but the fight did not finish then. Thirty or forty more dogs ran up and made a circle around the fight, watching silently. Curly tried to attack the dog who had bitten her; he bit her a second time, and jumped away. When she attacked him again, he knocked her backwards, and she fell on the ground. She never stood up again, because this was what the other dogs were waiting for. They moved in, and in a moment she was under a crowd of dogs.

    So sudden was it, and so unexpected, that Buck was taken aback. He saw Spitz run out his tongue in a way he had of laughing; and he saw Francois, swinging an axe, spring into the mess of dogs. Three men with clubs were helping him to scatter them. It did not take long. Two minutes later the last of the dogs was chased away. But Curly lay dead in the snow, her body torn almost to pieces. Curly's death often came back to Buck in his dreams. He understood that once a dog was down on the ground, he was dead. He also remembered Spitz laughing, and from that moment he hated him.

    Before he had recovered from the shock caused by the death of Curly, he received another surprise. Francois put a harness on him. Buck had seen harnesses on horses, and now he was made to work like a horse, pulling Francois on a sledge into the forest and returning with wood for the fire. Though his dignity was deeply hurt by becoming a work animal, he was too wise to rebel(反抗). It was all new and strange, but Buck did his best. Buck learned easily and under the combined teaching of Francois and his two mates, Dave and Spitz, two experienced sled dogs, he made remarkable progress. Before they returned to camp he knew enough to stop at "ho," to go ahead at "mush," to swing wide on the bends, and to stay clear when the heavy came shot downhill.

"Those three are very good dogs," Francois told Perrault. "That Buck pulls very well, and he's learning quickly."

    Perrault had important letters and official papers to take to Dawson City, so that afternoon he bought two more dogs, two brothers called Billee and Joe. Billee was very friendly, but Joe was the opposite. In the evening Perrault bought one more dog, an old dog with one eye. His name was Solleks, which means The Angry One. Like Dave, he made no friends; all he wanted was to be alone.

    That night Buck discovered another problem. Where was he going to sleep? Francois and Perrault were in their tent, but when he went in, they shouted angrily and threw things at him. Outside it was very cold and windy. He lay down in the snow, but he was too cold to sleep.

    He walked around the tents trying to find the other dogs. But, to his surprise, they had disappeared.

    He walked around Perrault's tent, very, very cold, wondering what to do. Suddenly, the snow under his feet fell in, and he felt something move. He jumped back, waiting for the attack, but heard only a friendly bark. There, in a warm hole under the snow, was Billee.

    So that was what you had to do. Buck chose a place, dug himself a hole and in a minute he was warm and asleep. He slept well, although his dreams were bad.

    I had reached the age of twenty-eight. Still, I doubted the letter from my past would make it to me, all these years later. It was a simple creative writing assignment from when I was eighteen. The teacher collected our letters to our future selves in self-addressed envelopes with stamps and promised to mail them ten years later. Yet so much time had passed. Would he even remember?

    Thinking back on the letter, I vaguely recalled giving my future self some advice. When you're eighteen years old, twenty-eight seems like a grown-up age but I wasn't feeling as grown up as I believed my younger self had expected me to be.

    When the letter finally reached me, I opened it eagerly. It began," How much do you bet this letter will never get to you "It continued to greet me casually as if we were having an IM (instant messaging) chat. My eighteen-year-old self was so stressed! As a senior in high school, facing the SATS and college applications, I was apparently not quite happy and hoped I wouldn't worry so much in the future, and that I wouldn't forget to be present and enjoy my life!

    Contrary to my belief, my eighteen-year-old self did not have any demands of me, or expectations I might have failed to meet. Instead, she wrote," I'll stand by whatever you do. Even if you are not who I'm imagining now, I'll support you, because maybe who I' m imagining is someone else, and you are-well you're not someone else, you're me."

    I was blown away, and tears welled up in my eyes at this self-acceptance through time. I had put a lot of pressure on myself to be the best version of myself that I could be. However, I came to realize what I would have accomplished in ten years' time would pale in comparison to how I'd feel and who I'd be.

    One night in 1966, Michael Chapman rushed into a folk-music club in Cornwall, England to get out of the rain, and soon found himself onstage playing the guitar.

    "They offered me a job to play for the rest of the summer. And I've been playing ever since," Chapman says. "I've told that story so many times, but it's absolutely true. If it hadn't been raining that night, I wouldn't be talking to you."

    The British guitar player has spent the 50 years since then on the road. He released some praised albums in the 1970s, but his health went downhill in the 80s and 90s. Like a lot of British artists in the 1960s, Chapman taught himself to play the guitar by listening to American jazz and blues records.

    Chapman actually taught photography, but quit when he was 26 to play music full time. When he was starting out, he was often compared to other British acoustic (原声的) guitar heroes of the time, like John Martyn and Bert Jansch.

    "The fascinating thing about Michael Chapman is that he doesn't fit in with those guys of his generation," says Andrew Male, a music journalist. "He's always- been an outsider. He never moved to London."

    And while he never became part of the London music scene, Chapman was noticed by those musicians. "The 70s caught up with him in the 80s," Male says. "He had a huge heart attack at the end of the 80s that nearly finished him off. When he made his way back into the world in the early 90s, people had forgotten about him."

    But not everyone. A younger generation of musicians in America, including Thurston Moore of Sonic Youth and a younger singer and guitarist named Steve Gumi, recently rediscovered Chapman.

    "We wanted to capture Michael's voice and character where he is now. You know, it's a little road-weary, but he still has it," Gunn says. "For me, it was really important to get that right," "He's the right old musician for present times," Male says. "I think the music he makes seems quite in tune with where we're at."

Two weeks earlier,my son,Ben,had got in touch.He'd moved to England with his mum when he was three and it had been 13 years since I'd 1 seen him.So imagine my 2 when he emailed me saying he wanted to come to visit me.

I was 3 !I arrived early at Byron Bay where we were supposed to 4 .The bay was 5 in sunshine,and there was a group of kayakers around 150m off the shore.Getting a little 6 ,I realized one kayak(皮划艇) was in 7 ."Something's not 8 !"I took off my T-shirt and 9 into the water.I saw there were two instructors on board and a man lying across the middle.He was 10 violently.Linking arms with one of the instructors,I helped 11 the young man out of the water.He was unconscious and as I looked at his face,something 12 to me.Those brown eyes were very 13 ."What's his name?"I asked the instructor."Ben,"he replied,and immediately I 14 .That stranger was my son! 

The instructors called an ambulance.15 ,after a brief stay in hospital,Ben was well enough to be allowed to 16 and later the family met up for dinner.We chatted about everything and then Ben 17 to me."I just want to say thank you,"he said."You 18 my life!"

I still can't believe what a 19 it was.I'm just so glad I was there 20 to help my son.

There was an encounter that later sparked scientists' investigations into using jellyfish as a greater source of food, as well as a potential ingredient in medicines and nutraceuticals. In the summer of 2013, while Stefano Piraino was wandering along the rocky shoreline, he noticed a washed-up jellyfish. Then, he tore off a piece and put it in his mouth. It was salty, crunchy and crispy from the sun. "It was very tasty, " remembers Piraino, a zoologist. After a few days of lying on the shore, their stinging cells(刺细胞)are deactivated, Piraino explains. Still, he warns that people should not eat jellyfish straight out of the sea, because raw jellyfish contains bacteria that can cause food poisoning. 

Recently, there have been numerous reports of jellyfish blooms—seasonal events where there is a large and sudden increase in jellyfish numbers. These population explosions break the balance of ocean ecosystems, and have the potential to harm biodiversity and reduce fish stocks. 

Some scientists, such as Piraino, believe one solution is broadening our palates(口味)since the world is in urgent need of sustainable food resources. Jellyfish can be integrated into traditional recipes and local cuisine. Not only are they high in protein, but the microalgae inside the cells of some jellyfish are rich in fatty acids. In fact, jellyfish is already eaten across Asia. In China, jellyfish has been eaten for more than 1, 000 years, with jellyfish salad a popular delicacy. 

Jonathan Houghton, a senior lecturer in marine biology, believes that jellyfish can be a better source of collagen(胶原蛋白). There are a number of companies already using jellyfish as a substitute(替代品) for cow and pig collagen, which is often used in medical treatments for humans. One British company says collagen from jellyfish offers a better choice, because their collagen can work with a wide variety of human cell types.
