With the Chinese language growing in popularity,the UK government plans to invest（投资）10 million pounds to help more kids learn Mandarin（普通话）.Do you think it is necessary for the UK pupils to learn Mandarin?Some people share their opinions online.

    Ted(UK): The learning of any language can be valuable and rewarding,but it is not suitable for everyone. Chinese is a difficult language to learn and the UK has a poor reputation for teaching foreign languages.Why should they learn Chinese when most people in the world speak English?

    Mark(US): I studied French for 2 years in high school and German for 4 years in college.I studied Mandarin informally for about 4 months before moving to China.Now I speak Mandarin every day as my wife doesn't speak English.But it is far from being fluent.Learning additional languages is a great thing,which offers a different perspective on the world around us.Nowadays,it's almost necessary to be able to speak more than just your native tongue.

    George(UK): No,unless they're taught from a very early stage of childhood.Mandarin is so difficult.If China really is going to dominate the world,it'll have to do so by speaking the world's dominant language—English.

    Sam(UK): I don't think Chinese will become as widely spoken throughout the world as English.It is too difficult to learn as a second language.To learn Chinese you completely have to devote yourself to learning how to write and read it.If you have to learn it besides other subjects you can't be good at it.But Chinese will become more popular, and that is a good thing.

    Mew Zealand's chief conservation (环保)officer，Lou Sanson, caused an argument in October suggesting that it should be time to start charging tourists for entering national parks. New Zealanders are keen fans of these parks. Many would be annoyed at having to pay. But many also worry about the incoming foreign tourists who have been seeking the same fun.

    In 2016 New Zealand hosted 3.5m tourists from overseas; by 2022 more than 4.5m are expected every year—about the same as the country's population. Tourism has become the biggest export. The national parks, which make up about one-third of the country, are a huge draw. About half of the foreign tourists visit one. They are keen to experience the natural beauty promised by the country's “100% Pure New Zealand” advertising campaign (and shown off in the film adaptations of “The Lord of the Rings” and “The Hobbit”，which were shot in New Zealand's breath-taking wilderness).

    But for every happy foreign couple posing for a selfie next to a tuatara (楔齿蜥)there is a NewZealander who remembers the way things used to be-when you could walk the tracks without running into crowds at every clearing. Many locals now wonder why their taxes, as they see it, are paying for someone else's holiday. Mr. Sanson would seem to agree. Entry fees could be used to upgrade facilities such as car parks and trails. A charge could also help reduce numbers at some of the popular locations by making it cheaper to use lesser-known, but no less beautiful, trails far away from home.

    Some are not so sure it would work. Hugh Logan, a former chief of conservation for the government who now runs a mountain climbing club, worries it would cost too much to employ staff to take money from hikers at entrances. It would also be difficult to prevent tourists from entering the parks without paying.

    Some argue that it would be easier to charge visitors a “conservation tax” when they enter the The Green Party the third-largest in parliament says that adding around NZ$18($12.50)is still acceptable to foreign tourists. But some travel companies don't quite agree with the idea. They note that tourists already contribute around NZ $l.l bn through the country's 15% sales fetter, such firms say, to use foreign tourists' contribution to this tax for the protection of the parks.

    Among the fiercest critics of a charge are those who point out that free access to wilderness areas is an important principle for New Zealanders, It is documented in a National Parks Act (法案) which inspires almost constitution-like devotion among the country's nature-lovers. Mr. Sans on has a rocky path ahead.

    Imagine a brand-new, magical pill which can measurably improve your memory, overall cognitive (认知的) performance, ability to learn new information, mood, ability to handle problems and more. Would you buy it?

    Yeah, yeah, you saw this coming: That pill exists, but not in pill form. You can have all of those benefits for free, and all it takes is going to bed a little bit earlier. So what are we to do to get a better night's sleep?

    First, learn how much sleep you need. Generally, if you're waking up tired, you're not getting enough. However, the gold standard of eight hours per night might not be right for you. A study from 2015 brought into question whether we need that magical number, so following your body is the best way to figure out the right rhythm. The only real guideline is to get as much sleep as you need to feel refreshed and energized the next day.

    Next, figure out your body's natural rhythm. Maybe after years of trying, you need to acknowledge that you're just not a morning person. And that's perfectly fine! Click the link and take the quiz to find out what kind of sleeper you are, and don't fight your body's natural sleep tendencies.

    Last, keep a consistent sleep schedule. This can be the most important part of your overall sleep quality We're all equipped with circadian clock (生物钟), which s that internal 24-hour timer that naturally tells us when to sleep, and the best way to getting rest and feeling rested is to keep this consistent. Fall asleep and wake up at the same time every day, and try to build as much regularity into your schedule as possible. And don't forget to keep your bedroom cool.

    Judy Wright and her husband decided to move closer to their son, Chris, who lived in Georgia. About a month after the move, Judy fell ill, suffering from her ongoing battle against Parkinson's disease.

    Her condition worsened rapidly and she required medical care at home. The family hired a nursing aid who canceled at the last minute. Instead, a woman named TunDe Hector showed up in her place.

    One day, TunDe shared a story with Judy and her family. She remembered a particularly difficult day in 2014, when a stranger had helped her with a kind gesture. She had run out of gas, and with only$5 in her pocket, was walking to a gas station, gas can in hand. A man saw her walking and turned his car around. He paid for her gas and gave her all the cash left in his wallet. Upon hearing the story, Judy's son, Chris, took off his hat and said, "That was me!” He was the stranger that had helped TunDe on that difficult day.

    During the care of Judy, the Wright family learned about TunDe's family and her own dream. The nursing aid, TunDe hoped that one day she could become an OB-GYN nurse.Her tuition was past due(逾期) and she had a family to care for, but she was determined to achieve that goal for herself and her family.

    Judy died on July 9,2017. Instead of flowers, her family asked mourners(悼念者) to donate to TunDe's education , to assist her in paying for her nursing school. In less than a week, they raised more than $8,000 and presented her with the surprise check.

    Mother Teresa (August 26, 1910-September 5, 1997) was a great woman, who did a lot to improve the social condition of mankind. Due to her contribution in serving the society, she was awarded the Nobel Peace Prize aged 69.

    She was brought up in a Catholic family. When she was only seven, she lost her father. Even as a young child, she was interested in the life of missionaries (传教士). At the age of 18, she decided that she would become a nun. She left her home and went to join the Sisters of Loreto. It was the first step that she made towards providing services for mankind.

    On the 7th of October in the year 1950, Mother Teresa received Vatican permission to start the Missionaries of Charity in Calcutta, the mission of which would be to take care of the needy, the homeless, and people who were shunned by the society. Then it had a number of branches all over the country. The journey of Mother Teresa's Missionaries of Charity started with the setting up of homes for "the Dying".

    In the year 1983, Mother Teresa suffered from a serious heart attack, while she was in Rome. However, she recovered. But, later in 1989, she again got an attack. Her health went worse and in the year 1991, she suffered from pneumonia. Taking her health problems into consideration, Mother Teresa decided to resign (辞职) from the post of head of the order.

    A secret vote was conducted in which all the nuns voted for the stay of Mother Teresa except herself. So, she agreed to continue serving as head of the Missionaries of Charity. Day by day her health was getting worse. On September 5, 1997, exactly nine days after her 87th birthday, this great soul departed for heaven.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play, catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, extra learning trials (尝试) increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables (乘法口诀表) are an exception (例外) to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.
