There are many wetlands (湿地) in China ‒ and some of them have become the world's important wetlands. The Chinese Yellow Sea Wetlands are {#blank#}1{#/blank#} them. They are in Yancheng, Jiangsu Province. They are {#blank#}2{#/blank#} to many different kinds of animals. The world's {#blank#}3{#/blank#} Milu deer nature reserve (自然保护区) is on these wetlands. More than 700 Milu deer live there. There are not many red-crowned cranes (丹顶鹤) {#blank#}4{#/blank#} in the world, but every winter, you can see some in the red-crowned crane nature reserve in the Yellow Sea Wetlands.

    The {#blank#}5{#/blank#} in the wetlands is neither too high nor too low. There is  {#blank#}6{#/blank#} rain and sunshine, too. They are a good place for wildlife. But offering food and shelter for special kinds of animals is not the  {#blank#}7{#/blank#} reason we need to protect wetlands. Wetlands are important {#blank#}8{#/blank#} they also prevent floods. But some people want to {#blank#}9{#/blank#} the wetlands to make more space for farms and less space for wildlife.

    More people are beginning to realize the {#blank#}10{#/blank#} of wetlands and wildlife. Every year, on Feb 2, many activities are held to teach people about the wetlands.

    English playwright Arthur Wing Pinero said, "Where there's tea, there's hope." Similarly, a Chinese saying goes that "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are the seven necessities to begin a day."

    Tea is, without doubt, welcomed all over the world. According to Statista, a German website for statistics (数据), global tea production reached about 5.8 million tons in 2018. It has become the most consumed beverage (饮品) in the world – after water, of course.

    According to the UN, tea is much more than just a hot drink. It's a big part of many cultures around the world. You probably know that people in China use top-grade tea to show respect when receiving important guests. Meanwhile, the British tradition of afternoon tea is an important part of that country's identity. Making Malaysia's pulled tea has become a sort of art form, where drinkers take pride in its entertainment aspects.

    Apart from its cultural significance (意义), tea is also a medicine, used from ancient times to modern day. "Tea is cold and lowers the fire," Chinese Ming Dynasty herbalist Li Shizhen once said. The health benefits of tea are still being discovered today: preventing heart disease, obesity and cancer have all been linked to drinking green tea, according to the National Center for Biotechnology Information in the US.

    Hot or cold, bagged or loose-leaf, tea is more than a drink – it's a social custom and also a magic medicine, a link to the past and a way of life.

    Where were dominoes (多米诺骨牌) from? Modern dominoes first showed up in Italy during the 18th century. But it is believed that the earliest dominoes were Chinese playing cards. Italian missionaries (传教士) in China may have brought the game to Europe. Do you think so?

    Do you like to play with dominoes? Dominoes are small rectangular (长方形的) pieces made of wood or plastic (塑料). People can place dominoes in different shapes. Then, they push one domino down and the rest of the dominoes fall one by one. It is interesting to watch.

    But placing dominoes is hard. To make sure the dominoes fall smoothly, the space between each domino is important. According to domino—play. com, if a domino is about 4 cm long, then the space between two dominoes should be1—2 cm. If the space is too big, the dominoes will stop falling halfway. If the space is too small, the dominoes will fall too quickly and won't look interesting.

    Beginners can start by putting dominoes in a straight line. This is the easiest shape. Professional (专业的) players can place dominoes in many other shapes, including big circles, beautiful flowers and even famous paintings.

    Horses are beautiful animals. They can be in different colors, and can run quickly. People like to watch horses because they are strong and beautiful.

    Horses are mammals (哺乳动物). The mother horse usually has one baby in spring, and feeds the baby milk. Horses have long legs and big eyes, so they can see almost all the way around them. They can walk and jump.

    Horses can live up to 20 or 25 years. Sometimes people can tell how old a horse is by looking at its teeth! They usually sleep by standing up. Horses only need about three hours of sleep per day!

    People need to take care of the horses "hooves". If a horse is doing a lot of walking on hard ground, people put horseshoes on them. When the hooves need trimming (修剪), people take off the horseshoes, and then give them new ones.

    For food, horses eat food such as grass, corn, apples and carrots. They don't eat other animals. Their stomachs are small, so they eat a little at one time, but they eat many times.

    Some horses are very famous. For example, Bucephalus, the famous horse of Alexander the Great. When Alexander was a boy, he got a horse. Nobody else could ride on it. Alexander named the horse Bucephalus and the horse carried him in many battles (战役). Here is another example. Napoleon had many horses, and Marengo became famous after Battle of Waterloo.

    If you had billions of dollars, would you donate almost all of it to charity? Well, that's what Mark Zuckerburg, CEO and founder of Facebook, just said he would do.
    Zuckerburg and his wife Priscilla Chan promised to give 90% of their Facebook shares to society. Right now that is about $45 billion, and they plan to donate the money to things like science and education.
    Many billionaires have done similar things. Bill Gates, creator of Microsoft, made The Giving Pledge, an activity in which billionaires promise donate more than half of their wealth to charities. This started in 2010, and now 139 people from 15 countries joined it.
    But giving back and helping others isn't just for big billionaires. People like Zuckerberg, and Gates may have more to give, but people with less are doing it, too.
    Especially around the holidays, people want to do their part and give back to people who are less lucky than them. Schools may have food collections where people bring a few food items, and together they can make a big donation to places like homeless people's homes.
    People also host special events like concerts of runs to be creative while raising money. Regular people donate whatever they can to US charities like the United Way and the American Red Cross.
    Then these charities are able to help US communities in different ways like education, health and improving the lives of the poor. These individual donations come together to make a big difference.
