Once a group of 17-year-old schoolboys decided to break the world basketball marathon record ( 马拉松记录). They wanted to play for ninety hours and add six hours to the record. Each team had nine players, with five at a time. The boys decided each person would play 21.5 hours and then rest for 2 hours. Then it started between both of the sides at 6 o'clock in the evening.

    The first night was very hard for the players. When it was their turn to rest, they were too exited(兴奋的) to fall asleep at once. After sleeping for a short time, they had to play again.

    On the second night, they fell asleep as soon as they stopped. Some of them had trouble with their feet and hands, but the only serious problem was a psychological one. Each boy was thinking: Why am I doing this? How can I play any longer?

    After the third night, the players knew they could finish the ninety hours. The basketball on the fourth night was very slow. But in the final hours, the players got better. For the last few minutes, the players looked as fresh as when they started. How happy everyone was!

    The Boy Made It!

    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. 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 (蜷缩) 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 again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholaswas 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(一期节目) of Man vs. Wild, Grylls is abandoned in a wild area andhas 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.

    What do butterflies have in common with the human spirit? Meet Maggie, a middle-aged wife and mother who was about to find out.

    Maggie wasn't rich like a millionaire or poor in a manner of being homeless. She was living an average comfortable life. It was made even better when a baby girl came her way. She and her husband made sure their daughter had her needs met and they were still able to take a yearly vacation by the beach.

    Maggie was a partner in her husband's business. They both had a different set of duties and everything was in balance. One day a severe blow came to her husband's business, and over a three-year period the business dropped out of sight. Her husband had to totally reinvent himself and was eager to start a new business. She was happy for him and supported him fully, but still the money was not coming in.

    Maggie began to feel guilty that she wasn't contributing with any kind of income. She began job-hunting and found filling out applications somewhat difficult, especially the part asking for job references. She was self-employed with her husband for almost 20 years, which seemed to mean nothing as she was never called for an interview.

    When she was job-hunting her mom became more ill than she had been and ended up in the hospital for a week. Once Maggie's mom returned home she became her mom's helper one day a week. She did everything that her mother was not able to do any more. Of course her mom would pay her for her lime and labor but she still felt she needed to find another source of income.

    One of the first applications she had filled out finally came through. She passed the interview and was told she was exactly what they were looking for. Although it was only part-time it was exactly what she wanted. It was important for her to be home when her daughter arrived home from school.

    Within a few weeks, though, she received an e-mail saying that the company had changed the job into a full-time position so that she was not qualified. Maggie felt betrayed and felt she had been lied to. That evening she was alone at home. She welcomed the aloneness and wanted to put herself in the bathtub to kill the lonely time.

    As she knew she would, Maggie began to cry, softly at first just from the sharp pain of being rejected. Three long years of struggle had finally overwhelmed her.

    When she was able to cry no more, she became worn out and gave up. It was at that moment that a silent idea came to her: why not offer elderly people home care assistance? Using another talent for computers she printed off some flyers and cards and distributed them to her church, grocery stores and even placed a small ad in the newspaper. Within a week she had procured two new customers. Now, even though she's not a CEO of a major company she feels happy and productive again.

    Before a butterfly can come out of its chrysalis (茧) it has to go through a lot of struggling. Each time it pushes out to escape, acids are being removed from its wings. If someone were to come along and break the chrysalis open for it then the butterfly would die from those acids. Actually the struggle is necessary for the butterfly to survive. Then in the stillness, when the struggle is over, the butterfly can come out and share its beauty with the world.

    We as humans are not any different.

    Cultures are based on social and linguistic(语言的) communities.

    In South Africa, we exist amongst diverse groups which are culturally different. This makes us multicultural. Toit, one sociologist in the U.S., explains that multiculturalism is more than the expression of cultural variety, and it also concerns communication. He adds that for multiculturalism to “succeed”, meaningful communication is a requisite.

    In multicultural countries, it is necessary that the education system encourages learners to become interculturally competent (胜任的). The process of becoming intercultural is a “personal transformation” from being cultural to being intercultural. This does not mean that a highly intercultural person's identity is culture-free. Rather, it is not rigidly bound by membership to anyone particular culture. Furthermore for learners to become interculturally competent, it is necessary that all involvers in the education system become aware of their own cultural background.

    Toit conducted a survey, the objective of which was to determine the problems experienced by learners in a multicultural learning environment. Two hundred questionnaires were administered. 55% believed that different values and beliefs were a major cause of the communication problems. Closer examination of the interactions showed that learners were in fact mostly associating with members of their own cultural groups. Toit points out that in an intercultural communication, people would be challenged by the sudden difference in culture, and this may force an evaluation or re-evaluation of their beliefs and values. 45% of the learners believed that there was lack of trust among their peers. The general lack of trust between two complete strangers leads to an uncomfortable situation. They said that when learners are asked to work in groups, they are unwilling to do so. They added that one of the many issues that contribute to such negative opinions was the language barrier.

    Last Sunday, my whole family went to the amusement park near our hometown. As we planned the day before, on my brother's 13th birthday. David was two years older than I.

The weather was perfect and everyone was happy. The park was not too crowded. "Fioda," said my brother, "do you want to go on that ride with me?" "Of course," I said. The ride was brand new. I saw commercials(广告) for this huge roller coaster(过山车） on television. I was so excited to ride it. As we got in line, we talked excitedly about what we might experience. We decided that we would both try to keep our hands in the air the whole time. We believed that would make it even more enjoyable. I was so busy talking to my brother that I missed the most important sign—-Empty your pockets before going on the ride. Something bad happened!

    The ride started. It was a really fast roller! Before I knew it, we were upside down. I felt my phone slipping（滑落） from my pocket. My hands were in the air, just as we had promised, and I didn't catch my phone in time. It hit me on the head, fell down to the ground and broke. My parents said I wouldn't have a new phone until I had enough money to pay for it. I need to be more careful. Next time, I'll pay better attention the warning signs as we wait in line for the ride.

    Six months after a Chinese scientist was widely condemned for helping to make the world's first gene­edited babies, he remains out of public view, and new information suggests that others may be interested in undertaking the same kind of work outside the United States.

    A clinic in the United Arab Emirates city of Dubai emailed scientist He Jiankui to seek training in gene editing, Stanford University bioethicist Dr. William Hurlbut said ahead of a speech Tuesday at the World Science Festival in New York.

    Hurlbut, whose advice He often sought, said He told him that scientists from multiple countries and families with inherited health problems had messaged support and interest in altering the genes of embryos(胚胎)to prevent or treat disease. Hurlbut gave The Associated Press the email the Dubai clinic sent to He in December but decided to hide the clinic's name.

    "It reveals what eagerness there is out there to use this technology" and the need "for some sort of practical governance" of it, Hurlbut said.

    Jennifer Doudna, a University of California, Berkeley, co­inventor of the CRISPR gene­editing tool that He used, said that she also has heard of others who want to edit embryos.

    "I think they're entirely credible," she said of such reports. Doudna, who was also a speaker at the New York festival, said the field needs to focus on setting specific principles for how and when such work should proceed.

    "The technology is frankly just not ready for clinical use in human embryos," although research should continue, she said. Doudna is paid by the Howard Hughes Medical Institute, which also supports AP's Health and Science Department.

    Scientists and policy leaders have been debating how to set international standards or controls since He claimed in November that he had altered the genes of twin girls at conception(怀孕)to try to help them resist possible future infection with the AIDS virus.

    Editing embryos is outlawed in many countries because it risks damaging other genes, and the DNA changes can be passed to future generations. Many scientists have condemned He's work, and attention has fallen on other scientists who knew or strongly suspected what He was doing.
