    A new study suggests climate conditions in the Sahara Desert, one of hottest, driest and most deserted areas in the world, have changed from wet to dry a about every 20,000 years.

    But previous evidence has suggested the Sahara did not always experience such extreme heat and dry conditions. At times, the Sahara Ranged to a very wet climate. This permitted plants and animals to develop and grow and led to the creation of human settlements. Now, they have discovered more evidence, which, the lead researcher David Mc Gee says, supports the idea that the Sahara's climate kept changing between wet and dry about every 20,000, years.

    McGee reported these climate changes were mainly driven by changes in the Earth's(地轴)as the planet travels round the sun .This process affects the amount of sunlight between seasons. Every 20,000 years the Earth receives more strong summer sunlight. When the Earth's axis changes again, the amount of sunlight is reduced. This season change happened continuously every 20,000 years. The other part of the season produced rainy conditions, resulting in a wetter, greener, plant-rich environment. When the rainy activity weakens, the climate becomes hot and dry, like the Sahara remains today.

    The scientists based their research on dust collected from ocean sediment(沉积物)in the Atlantic Ocean bottom off the coast of West Africa. The dust contained layers (层)of ancient sediment built up over millions of years. Each layer could contain traces of Saharan dust as well as the remains of life forms. This information was used to assess over what time period the dust had built up. This led to the overall finding that the Saharan changes from wet to dry climates happened every 20,000 years.

David McGee said that today we only see the Sahara Desert as an extremely deserted and "inhospitable" place. The new study suggests that the area's climate has changes between grasslands and a much wetter environment, and back to dry climates, even over the last quarter million years. McGee says he thinks the latest research can be valuable in studying the Sahara's history as it relates to human settlement.

    My first week in the United States was a cultural shock. Everything felt new to me, including the style of conversation, the community I lived in and even the type of food people ate.

    In our community back home, people eat mutton and chicken. Pork and beef are also common among other communities, but eating beef is taken as an illegal act. Unlike Nepal, eating beef is common in the West where most of the people follow religions other than Hinduism.

    Food is just an example. When people move from one part of the world to another, they should adapt(适应)themselves to the new culture. For example, going to the bars or getting drunk is not acceptable in my community, but it is common in the US after a certain age.

    I was raised in a traditional Hindu family in Nepal. We have a conservative(保守的,谨慎的)opinion towards marriage. Arranged marriages(包办婚姻)are common in which families decide whether the two should get married. Free love marriages are not allowed and are seldom seen. Same-sex marriage is also considered impossible.

    To me, culture is a matter of habit. The culture is so deep-rooted in people's minds that most people are against changes. It is always easy for them to do what they have been doing throughout their life. It may be difficult for anyone to adapt to a new culture.

    However, with travel being an unavoidable thing for modern people, one always comes across different cultures. In such cases, one should be respectful and adaptive to the culture other people follow. The world is always a better place to live in when we have spaces for people of all cultures.

    Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.

    One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.

    Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.

    Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.

    Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.

    Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer's theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.

    According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.

    The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK's University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”

    As is often the case, however, there are others who find the theory less convincing. Cambridge University's paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It's only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.

    While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.

    Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize—which is often referred to as the Nobel Prize in architecture—on February 28. He is the first Chinese citizen to win this award.

    Wang serves as head of the Architecture Department at the China Academy of Art (CAA). His office is located at the Xiangshan campus (校园) of the university in Hangzhou, Zhejiang Province. Many buildings on the campus are his original creations.

    The style of the campus is quite different from that of most Chinese universities. Many visitors were amazed by the complex architectural space and abundant building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.

    Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional techniques to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements (元素).

    Wang's works show a deep understanding of modern architecture and a good knowledge of traditions. Through such a balance, he had created a new type of Chinese architecture, said Tadao Ando, the winner of the 1995 Pritzker Prize.

    Wang believes traditions should not be sealed in glass boxes at museums. "That is only evidence that traditions once existed," he said.

    "Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created," he said.

    "Today, many Chinese people are learning Western styles and theories rather than focusing on Chinese traditions. Many people tend to talk about traditions without knowing what they really are," said Wang.

    The study of traditions should be combined with practice. Otherwise, the recreation of traditions would be artificial and empty, he said.

    The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other forever. He sent his camera crew out one evening to film the sunset for him.

    The next morning he said to the men, "Have you provided me with that sunset?"

    "No, sir," the men answered.

    The director was angry. "Why not?" he asked.

    "Well, sir," one of the men answered, "we're on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset."

    "But I want a sunset!" the director shouted. "Go to the airport, take the next flight to the west coast, and get one."

    But then a young secretary had an idea. "Why don't you photograph a sunrise," she suggested, "and then play it backwards? Then it'll look like a sunset."

    "That's a very good idea!" the director said. Then he turned to the camera crew and said, "Tomorrow morning I want you to get me a beautiful sunrise over the sea."

    The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o'clock they took it to the director. "Here it is, sir," they said, and gave it to him. He was very pleased.

    They all went into the studio. "All right," the director explained, "now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the 'sunset' behind them."

    The "sunset" began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.

    The birds in the film were flying backwards, and the waves on the sea were going away from the beach.
