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.

    If you watch British television on Friday March 15,you might be surprised to see celebrities wearing funny red noses and joking around. But don't worry. They're not mad. It's all part of a biannual fund-raising event called Red Nose Day.

    Organized by the charity Comic Relief, founded in 1985 by two British comedians, the aim of the event it is to raise money to fight poverty and injustice in the UK and Africa. Celebrities and public figures support the event by making appearances on comic TV shows broadcast by the BBC. This year, for example, UK Prime Minister David Cameron appeared in a music video by One Direction, which the band produced for the event.

    But Britons don't just raise money for charitable causes on one day a year. They do it all year round. One way of doing so is-by shopping in charity shops. These small, inconspicuous shops sell clothes, books and household goods just like any other shop But there's one big difference—everthing sold in the shops is second-hand.

    There are nearly 10,000 charity shops in the UK, according to the Charity Retail Association. Their business model is simple: Anybody who has things they don't want anymore can donate them to a charity shop, where they are checked for damage, cleaned and priced. Most items go back on sale at a small part of their original price and the money that is made by selling them is used for a charitable cause.

    The idea of buying used clothes may sound off-putting, but for shoppers who have less spending money, such as the elderly or those in low-paying jobs, it has been a welcome option for years. Now, shopping at charity shops is also becoming popular with young people looking for alternative fashion." You can find very unique clothes for a very cheap price. It doesn't bother me that other people may have worn them. I simply wash them before I wear them," said Anne Marie, a 19-year-old Internet user from the US, in a comment on a Yahoo forum.

    So next time you spot a charity shop, why not go inside? Who knows, you might find a lovely dress for just a few pounds. Even better, you can enjoy wearing it in the knowledge that your money helped a good cause.

    In the late 1990s, Google was just a start-up company operating out of a garage in PaloAlto, California. Co-founders Larry Page and Sergey Brin started the company while studying at Stanford University. Google's founders and its employees, then understood some of the challenges that entrepreneurs(创业者) around the world may face. An entrepreneur is a person who starts a business. They must be willing to risk financial loss in order to make money.

    Mary Grove is the director of a program called Google for Entrepreneurs. She said Google wants to help new start-up businesses grow and be successful.

Google for Entrepreneurs has opened campuses around the world. Entrepreneurs in each city can use Google's

    buildings without paying.Entrepreneurs can work with each other and learn from people who are more experienced in business.

    Yeram Kwon is the head of a company in South Korea.Her business is called L.M.Lab. It makes a product that helps people learn to perform the lifesaving technique called CPR. She said she has learned how to solve some of her business problems by attending Google events in Seoul.

    Outside of its own buildings in these cities, Google provides financial support and resources for partner organizations around the world. Building partnerships is a way for Google to spread the idea of entrepreneurialism around the world. Google can use its network to help find people who want to invest in start-up businesses. Those people need to be ready to take risks. That is something Kwon said that makes some Koreans uncomfortable. "Most

    Korean people think that it is much safer to work for big companies like Samsung and LG," she said. But, Kwon said the Korean government and technology companies are now supporting people willing to take business risks.

    For all the technological wonders of modem medicine, health care-with its fax machines and clipboards (写字板) —is out of date. This outdated era is slowly drawing to a close as the industry catches up with the artificial-intelligence (AI) revolution.

    Eric Topol, an expert in heart disease and enthusiast for digital medicine, thinks AI will be particularly useful for such tasks as examining images, observing heart traces for abnormalities or turning doctors' words into patient records. It will be able to use masses of data to work out the best treatments, and improve workflows in hospitals. In short, AI is set to save time, lives and money.

    The fear some people have is that AI will be used to deepen the assembly-line culture of modem medicine. If it gives a "gift of time" to doctors, they argue that this bonus should be used to extend consultations, rather than simply speeding through them more efficiently.

    That is a fine idea, but as health swallows an ever-bigger share of national wealth, greater efficiency is exactly what is needed, at least so far as governments and insurers are concerned. Otherwise, rich societies may fail to cope with the needs of ageing and growing populations. An extra five minutes spent chatting with a patient is costly as well as valuable. The AI revolution will also enable managerial accountants to adjust and evaluate every aspect of treatment. The autonomy of the doctor will surely be weakened, especially, perhaps, in public-health systems which are duty-bound to cut unnecessary costs.

    The Hippocratic Oath (誓言) holds that there is an art to medicine as well as a science and that "warmth, sympathy and understanding may outweigh the surgeon's knife or the chemist's drug". There's lots of sense in it: the patients of sympathetic physicians have been shown to recover better. Yet as the supply of human carers fails to satisfy the demand for health care, the future may involve consultations on smartphones and measurements monitored by chatbots. The considerately warmed stethoscope (听诊器), placed gently on a patient's back, may become a relic of the past.

    Each year, hundreds of thousands of wild animals around the world are killed in trophy hunting—the organized shooting of animals for pleasure. The hunters then bring parts of the animal home with them as their "trophy" to remember the hunting.

    Trophy hunters pay big money to kill animals. Some of the money goes to helping wildlife protection. Trophy hunting also attracts business, which encourages people to preserve land and breed(饲养) animals that would otherwise be endangered. Cathy Dean, head of the Save the Rhino Charity, says that at the start of the 1900s there were only 50–100 southern white rhinos. Now, there are around 18,000. This is partly because some of them were raised specially for trophy hunting.

    But things don't usually go on one way. According to WWF, elephant populations have fallen from 1.3 million to just over 400,000 since the 1980s. Over the same period, hunters from around the world have taken home more than 100,000 African elephant trophies. Trophy hunting is not illegal(非法的) but unfair on the animals. In 2015, Cecil the lion was shot by a US trophy hunter. Cecil was a beloved lion in Zimbabwe, Africa. Cecil was lured with bait(诱饵), shot with an arrow and struggled in blood for more than ten hours before his hunters tracked and finished killing him. His son, Xanda, met a similar fate two years later.

    Cecil's death caused worldwide outrage and protests(反抗) against trophy hunting. Countries including Australia, France and the Netherlands banned(禁止) the import of lion trophies—they stop hunters from being allowed to bring home parts of the animal they kill. They believe that people will stop trophy hunting because the activity might lose its attraction if hunters can't bring their trophies home.

    The UK Government said that it would consider a ban on trophy-hunting imports by 2017, but no action had been taken. In April 2019, a letter by protesters against trophy hunting was sent to the UK government asking to ban trophy-hunting imports. On 7 May, the official in charge of the environment, Michael Gove, said that the UK would not ban the imports for the time being. This left the world in a state of a shock. Hopefully the UK will place a ban on trophy-hunting imports, which would be an important message and inspire others to treat animals better. We're waiting for the day to come.

    If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.

    The scientists studied the genes of thousands of people between the ages of 16 and 102.The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.

    It is important to remember these are connections which are not proven causes. Scientists call this correlation. Just because something is connected to something else does not mean one of those things caused the other. And it's worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.

    Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance. He said sometimes there has been a huge amount of proof showing that people he was defending broke the law. He had them wear glasses and they weren't found guilty.

    Glasses are also used to show someone is intelligent in movies and on TV. Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and hip (时髦的). However, that hasn't stopped many celebrities from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.
