    When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.

    Salvador Dali (1904-1989) was one of the most popular modern artists. The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings, sculptures, drawings and more. Among the works and masterworks on exhibition the visitor will find the best pieces, most importantly The Persistence of Memory. There is also L'Enigme sans Fin from 1938, works on paper, objects, and projects for stage and screen and selected parts from television programmes reflecting the artist's showman qualities.

    The visitor will enter the World of Dali through an egg and is met with the beginning, the world of birth. The exhibition follows a path of time and subject with the visitor exiting through the brain.

    The exhibition shows how Dali draws the viewer between two infinities (无限). “From the infinity small to the infinity large, contraction and expansion coming in and out of focus: amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,” explains the Pompidou Centre.

    The fine selection of the major works was done in close collaboration (合作) with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg.

    Mark Twain, the famous American writer and a great master of humor, liked to play jokes on others. But once a joke was played on him. One day Mark Twain was invited to give a talk in a small town. At lunch he met a young man, one of his friends.

    The young man said that he had an uncle with him. He told Mark Twain that his uncle never laughed or smiled, and that nobody and nothing was able to make his uncle smile or laugh.

    "You bring your uncle to my talk this evening," said Mark Twain. "I'm sure I can make him laugh."

    That evening the young man and his uncle sat in the front. Mark Twain began to speak. He told several funny stories and made everyone in the room laugh. But the man never even smiled. Mark Twain told more funny stories, but the old man still kept quiet. Mark Twain continued to tell his funny stories. Finally he stopped. He was tired and quite disappointed.

    Some days later, Mark Twain told another friend what had happened." Oh," said his friend, "I know that man. He's been deaf for years."

    Houses fall down. Trees fall over. Large holes form in the ground. Could Alaska be sinking? That's what some villagers in Alaska have been asking themselves recently and scientists think they know why. Warmer temperatures may be causing Alaska's frozen ground to thaw (解冻).

    About 85 percent of Alaska's land surface has permafrost (永久冻结带). Permafrost supports the ground above it—including trees, houses, and roads. But why is the permafrost thawing?

    Some scientists say that human-caused pollution is leading to global warming. And most scientists agree that Alaska has been getting warmer. They say that the warmer temperature is causing permafrost to thaw in some areas. The thawing permafrost can cause problems for people, plants, and animals.

    The collapsing (倒塌) is a problem in the villages in Alaska which are built on permafrost, and some of them may have to move to safer ground, where there is no permafrost.

    The Alaskan town of Glennallen saw its old post office collapse. And, according to James Walters, a permafrost expert at the University of Northern Iowa, house-moving companies have been very busy.

    “Melting permafrost can also destroy trees and forests,” Walters said. “When holes in the ground form, trees fall into them and die. This could turn a forest into a swamp (沼泽), and animals which need the forests will have to move elsewhere.”

    “The melting could cause severe problems.” Walters says, “This could take hundreds of years, but in the end Alaska will look quite different from what it looks like now.”

    One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. "One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states." said Neville Alexander, Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town.

    In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions(规定) was the 1994 "Toubon law" in France, and the idea has been copied in many countries since then. Such efforts to govern language use are often considered as futile by language experts, who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.

    It is especially difficult for native speakers of English to understand the desire to maintain the "purity" of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world, but that has not been a barrier to acquiring superiority and power. Another reason for the failure of many native English speakers to understand the role of the state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.

    The need to protect national languages is, for most western Europeans, a recent phenomenon—especially the need to ensure that English does not unnecessarily take over too many fields. Public communication, education and new ways of communication promoted by technology, may be key fields to defend.
