Manners nowadays in big cities like London are particularly non-existent. It's nothing for a big, strong schoolboy to push an elderly woman aside in the dash for the last remaining seat on a bus, much less stand up and offer his seat to her, as he ought to. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly always one from the older generation.

    This question of giving up seats in public transport is much argued by young men, who say that, since women have claimed equality, they no longer deserve to be treated with courtesy and that those who go out to work should take their turn in the rat race like anyone else. Women have never claimed to be physically as strong as men. Even if it's not agreed, however, that young men should stand up for older women, the fact remains that courtesy should be shown to the old, the sick and the burdened. Are we really so lost to all ideals of unselfishness that we can sit there indifferently reading the paper or a book, saying to ourselves "First come, first served", while a gray-haired woman, a mother with a young child or a cripple stands? Yet this is too often seen.

    Older people, tired and easy annoyed from a day's work, aren't angels, either-far from it. Many an argument or an insulting quarrel breaks out as they feel tired of pushes in the queue and shove(猛推) each other to get on buses.

    If cities are to remain pleasant places to live in at all, however, it seems necessary, not only that communication in transport should be improved, but also that communication between human beings should be kept smooth and polite. Shop assistant won't bother to assist, taxi drivers shout at each other as they dash dangerously round comers, bus conductors pull the bell before their desperate passengers have had time to get on or off the bus, and so on. It seems to us that it's up to the young and strong to do their small part to stop such deterioration(恶化).

    Everyone can benefit a lot from reading books. The following is about various benefits of reading books.

    {#blank#}1{#/blank#} Whenever you read something, you learn information that you wouldn't have known. If you want to learn new words, reading books is a great way to enlargeyour vocabulary.

    {#blank#}2{#/blank#} Similar to solving puzzles, reading books allows your mind to practice its processing skills. Going without books for too long will turn your mind into mess.

    One of the primary benefits of reading books is its ability to develop your thinking skills. {#blank#}3{#/blank#} Wherever you are faced with a similar problem in real life, your mind is able to put its mystery solving skills to a test.

    The information in books can be referred to over and over again. For example, reading a cookbook allows you the chance to review the cooking steps whenever you need to. {#blank#}4{#/blank#} Don't even think about writing the information down because you may lose the paper sooner or later.

    These are just some of the wonderful benefits of reading books. {#blank#}5{#/blank#} If you can't even go outside, you can download free e­books online and read them on your computer. That way, you can see how useful reading can be for yourself.

    Life is full of funny moments, and not just for humans.

    Over the years, studies by various groups have suggested that monkeys, dogs and even rats love a good laugh. People, meanwhile, have been laughing since before they could talk.

    Jaak Panksepp, a professor at Bowling Green State University, US, said he would not be surprised if positive feelings could be produced in some animals. Dolphins, for example, have long attracted animal researchers because of the complex (复杂的) ways in which they communicate: a rich variety of sounds of different rhythms. A decade ago, researchers studying dolphins at the Kolmarden Wildlife Park in Sweden noticed a set of sounds the dolphins made during play-fighting. They concluded that the purpose of the sound was to suggest that the situation was pleasant and to prevent it from a real fight.

    Panksepp has even seen evidence of joy in crayfish (小龙虾). When given small amounts of drugs such as cocaine (可卡因) in a certain place, they appear to connect that location with pleasure. “Given the chance, they will always return to that place, perhaps in the hope of getting more,” he says. Panksepp wasn't sure it equals the same happiness that humans get from cocaine, but said it “could be in the same evolutionary category”.

    More studies are needed to really understand animals' laughter. Strangely enough, the answers may help with our own desires for cures for mental illnesses. Panksepp's experiments may soon lead to a new antidepressant (抗抑郁) drug that works by using the pathways in the brain behind positive feelings and joy. Perhaps pleasure and laughter in the animal world will help solve the depression in our own species one day.

    As a Chinese saying goes, “Taste is actually a memory of childhood”. Local specialty food may not be popular among all people, but it offers outsiders a glimpse of local culture and history.

    Gongcheng “oil tea” is such a kind of food that would be considered “weird” by many first-time visitors to the remote county in the north of the Guangxi Zhuang Autonomous Region. Many people dislike its bitter and astringent（涩的）flavor when they take a sip.

    “It felt like drinking Chinese herbal medicine. I never expected that I would gradually accept it afterwards, and even become addicted to it,” said a traveler surnamed Zhang who comes from Shijiazhuang in northern China's Hebei province.

    Langshan village is said to be birthplace of Gongcheng “oil tea” whose ideal ingredients are green tea and fermented（发酵）tea. The village has preserved well its buildings and roads dating back to late Qing Dynasty (1644-1911), as well as its traditional way of making the special tea.

    Lin Fengyou, 60, introduced the cooking process. She looks younger than her age, and attributes this to the benefits of drinking “oil tea” throughout the year.

    The first procedure is to use a wooden hammer to pound the tea while heating it in an iron pot, and then add edible（可食用的）oil and boiled water afterwards. She filters off the solid residues（余渣）, and pours the glue-like green tea soup into bowls. Then, she adds salt, caraway seed（葛缕子籽）, green onion, dried rice, fried groundnuts, sliced taro（芋头）and fried beans.

    The taste of the “oil tea” is a mixture of the distinctive（特有的）flavors of all its ingredients. Local people usually eat it together with glutinous rice（糯米）balls, rice dumplings and glutinous rice cake.

    The villagers consume “oil tea” three times a day. The tea soup is a healthy and refreshing food. “The tea soup to us is coffee to Westerners”, said Lin. “But it is tastier.”

    You don't have to be a superhero to help the environment. Even small, simple actions can add up to big change. People around the world will celebrate Earth Day on April 22. But anyone – including kids – can work to help the earth at any time. TFK (Time for Kids) talked to a few kids about how they are protecting the planet. Let them inspire you!

    Mari, 10, lives in Flint, Michigan, where people have been without clean drinking water since 2014. That is when the water became polluted with lead（铅）. Children in Flint have suffered from health problems due to lead poisoning. Mari has worked hard to spread awareness of Flint's water crisis by organizing fundraisers and other events.

    At age 3, Ryan went with his dad to recycling center near his home, in Orange County, California. The next day, Ryan began collecting recyclables from neighbors. Soon, Ryan's Recycling Company was born. “Recycling keeps bottles and cans out of the ocean,” Ryan, now 8, told TFK, “so animals don't get sick from them and die.” So far, Ryan has helped customers recycle 320,000 bottles and cans. He has also donated nearly $6,000 to the Pacific Marine Mammal Center.

    Joris, 11, has always loved cheetahs. When he learned that the big cats might disappear in his lifetime, he set out to help protect them. Joris began raising money. So far, Joris has raised more than $14,000. The money goes to a wildlife sanctuary（避难所）in Namibia, a country in Africa. This helps prevent the animals from being killed. Jorin has spent three summers volunteering at the sanctuary.

    David Cameron is urging today's youngsters to abandon French to concentrate on the tongue of the future—Mandarin(普通话)。

    Cameron said: "I want Britain linked up to the world's fast-growing economies. And that includes our young people learning the languages to seal tomorrow's business deals.”

    "By the time the children born today leave school, China is to be the world's largest economy. So it's time to look beyond the traditional focus on French and German and get many more children learning Mandarin.” To strengthen his message , he quoted Nelson Mandela—the former president of South Africa who said "If you talk to a man in a language he understands that goes to his head; if you talk to him in his own language that goes to his heart.”

    Cameron said that a partnership between the British Council (英国文化协会) and Hanban will double the number of Chinese language assistants in the UK by 2016 and provide increased funding to schools of offering Mandarin as a language choice. In a development of the UK—China School Partnership programme , funding will also be provided for 60 headteachers to make study visits to China in 2014.

    In recent research the British Council found only 1% of the adult population speaks Mandarin to a level that allows them to conduct a basic conversation. Just 3,000 pupils in England, Wales and Northern Ireland entered for Chinese languages GCSEs in 2013, putting it far behind the traditional choices of French with 177,000, Spanish with 91,000 and German with 62,000 entrants(加入者), as well as Urdu, Polish and Arabic.

    Professor Dame Helen Wallace, the British Academy's foreign secretary, said, " a lack of qualified teachers could be a barrier to improve its popularity.”

    Laura Chan, one of the co—founders of a bilingual Mandarin—English primary school, said the prime minister's announcement was good news for the status of Mandarin. She said, "It's a great help. It will increase people's awareness of Mandarin as a language they can learn.”
