Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset （思维模式） helps them embrace learning a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    Yellowstone National Park.☞文章内容an easy day hike or boat trip can turn into a battle for survival.

    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. 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 attempts or tries to increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, and bicycle riding 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 pass 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.

    China is known for its long history, rich culture, and cute pandas. It's also known for some of the worst air quality in the world. But the Asian country is now using a natural weapon against air pollution – trees.

    In February, China's government announced plans to cover at least 32,400 square miles with forest. That is about the size of Ireland. Some 60,000 soldiers will take charge of the tree-planting program. Most of the trees will be planted in Hebei Province. That is an area surrounding China's capital, Beijing.

    Huang Wei is an environmentalist who works for Greenpeace East Asia. She is optimistic about the plan. “Trees act as a sink to absorb carbon dioxide and other pollutants,” she said. Carbon dioxide is a gas that traps the Earth's heat. It contributes to global warming.

    Why is China's air filled with harmful chemicals? It's because the country relies on coal-fired power plants. When coal is burned, PM2.5 is produced, PM2.5 is a pollutant. It can cause shortness of breath, heart attacks, and even death.

    Just two years ago, pollution levels were so high in Beijing that schools and factories had to close. Huang hopes China's tree-planting plan will reduce the nation's suffering from air pollution.

    The Chinese government is getting help from others in its drive to make the nation greener. Stefano Boeri is an Italian architect and urban planner. He is leading an effort to plant vertical（垂直的）forests in China.

    Boeri's designs have already taken root in the city of Nanjing, China. That's where the Nanjing Green Towers are under construction. The building has two towers. Thousands of trees and hanging plants will grow on the balconies and rooftops.

    Boeri says his goal is to design buildings that help the environment and improve air quality. He also hopes to encourage a new generation of green architects.

    ⒈Siem Reap, Cambodia

    Siem Reap is a fast-growing city with plenty of new hotels, restaurants and nightclubs. But many people are here not because of the city itself, but for the things nearby: amazingly well-preserved ancient temples. Even if you have the worst jet lag (时差反应) ever, drag yourself out of bed to be at Angkor Archaeological Park when it opens. The sunrise over Angkor Wat is worth losing sleepover.

    ⒉Rome, Italy

    Rome is a city of contrasts (差异) — where else on earth could be home to both the Vatican and La Dolce Vita? Rome is unique in that it offers a great combination of different art, culture and food. If your preference is for sports, then Rome also has a lot to offer. In terms of music and live entertainment, a lot of the most famous Italian and international artists also tend to include Rome on European and world tours.

    ⒊New York, America

    The first time you go to New York, go ahead and be a sightseer- everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighborhood and go deep. You will find hole-in-the-wall bars, strange shops...Exploring the non-touristy side of New York is an extremely rewarding experience for a traveler.

    ⒋Istanbul, Turkey

    Europe and Asia meet in Istanbul. Throughout this energetic city, you will find centuries-old churches and markets happily coexisting (共存) with modem restaurants, galleries and nightclubs. Though no longer a capital, Istanbul is the heart of the Republic of Turkey and the financial center with a large population.

Chinese President Xi Jinping once said. "Heroes come from the people." Every year, there are ordinary people spreading positive energy (正能量) and touching our hearts. Let's take a look at some of them.
