Happiness means different things to different people. For Mary, who has {#blank#}1{#/blank#} severe sleeping problem, happiness is as simple as having a good night's sleep.

    Bed was once a place {#blank#}2{#/blank#} Mary went to rest after a long, hard day. {#blank#}3{#/blank#}, she has not had a full night's sleep in almost six months. Her doctor said that {#blank#}4{#/blank#} (count) sheep might help her fall asleep. She tried this, but soon got tired of it after it failed to work. She finds the nights without sleep almost {#blank#}5{#/blank#} (bear) . She is always sleepy and lacks energy during the day.

    Mary is not alone. Studies show that more than one in three people worldwide struggle with getting enough sleep. It often takes on different {#blank#}6{#/blank#} (form) : some people can get to sleep, but wake up much too early; some get a full night's sleep, but are {#blank#}7{#/blank#} (disappoint)  to find that they still feel tired when they wake up; others, like Mary, find {#blank#}8{#/blank#} difficult to fall asleep in the first place.

    Specialists say that people should not worry too much about this problem. In most cases , a lack of sleep {#blank#}9{#/blank#} (cause) by anxiety and pressure. It is important to keep yourself {#blank#}10{#/blank#} good spirits and to be positive. 

    It is {#blank#}1{#/blank#} (say) that in the year of 300 AD, there was a kind old man and his name was Saint Nicholas. He was always ready to help the poor and often gave {#blank#}2{#/blank#} (present) to them.

    Today, Father Christmas is {#blank#}3{#/blank#} imaginary figure, but {#blank#}4{#/blank#} (near) all young children believe in him. They think he is an {#blank#}5{#/blank#} (attract) old man with a long white beard {#blank#}6{#/blank#} a long red robe.

    {#blank#}7{#/blank#} the night of the twenty-fourth of December every year, Father Christmas from some cold northern land comes down the chimney of the fireplace  {#blank#}8{#/blank#} (put) presents by the beds of children or to fill their stockings. So children go to bed that night, {#blank#}9{#/blank#}  (hang) up their stockings, and on Christmas morning they wake to find them full of presents. Of course, it's really  {#blank#}10{#/blank#} (they) parents who fill the stockings.

    The best way to deal with sports injuries is to keep them from happening in the first place. Knowing the rules of the game you're playing and using the right {#blank#}1{#/blank#}(equip) can go a long way toward preventing injuries. If you think you've been injured, pull {#blank#}2{#/blank#}(you) out the game or stop {#blank#}3{#/blank#}(do) your activity or workout. Let a coach or parent know what happened in case you need to see a doctor. Serious head and neck injuries happen most often in athletes {#blank#}4{#/blank#} play body-contact sports like football. Keep the injured person still with his or her head {#blank#}5{#/blank#} (hold) straight while someone calls for emergency {#blank#}6{#/blank#}(medicine) help. If the person {#blank#}7{#/blank#}(lie) on the ground, do not try to move him or her.

    Your first question after a sport injury will {#blank#}8{#/blank#}(probable) be, “When can I play again?” This depends on the injury and what your doctor tells you. Even if you can't return to your sport right away, a doctor might have suggestions and advice {#blank#}9{#/blank#} what you can do to stay fit. Always check with your doctor {#blank#}10{#/blank#} trying any activity following an injury.

    For you, the "Clear and Bright" day that falls in every April might be no more than just another holiday — the fact that it comes with three days off school matters to most students {#blank#}1{#/blank#} more than the fact that it is part of the 24 solar terms.

But the UNESCO has recognized the importance of the 24 solar terms. This ancient system that Chinese people have used to keep track of the time of year {#blank#}2{#/blank#} (add) to the UNESCO list of Intangible Cultural Heritage of Humanity on Nov 30.

For starters, you may have heard your mom say: "The sanfu days are almost over. The heat won't be here for long." The sanfu days are a period of time that {#blank#}3{#/blank#} (fall) in summer, somewhere {#blank#}4{#/blank#} Minor Heat (in July) and Autumn Equinox (in September). The coldest days, or the sanjiu days, are similar. They cover the 27 days {#blank#}5{#/blank#} (follow) Winter Solstice.

    In some places, solar terms guide people's lives through special foods, {#blank#}6{#/blank#} (culture) events and healthy living tips. For example, people from northern China are in the habit of eating dumplings on the day of Winter Solstice. And on Start of Autumn, some people treat {#blank#}7{#/blank#} to a big feast, especially of meat, something they call "putting on autumn weight", or tieqiubiao.

    But no matter {#blank#}8{#/blank#} differently people celebrate the 24 solar terms, they have been here for a long time and could last forever.

    According to Chinese writer and academic Yu Shicun, unlike many other examples of intangible cultural heritage – Peking Opera and Chinese Zhusuan, for example – the solar terms are neither regional (地域的) nor a type of art or skill. Instead, the system is a philosophy of time, {#blank#}9{#/blank#} applies to everything. And this means they are {#blank#}10{#/blank#} (likely) to die out.

    Mochi (年糕) is a traditional food popular in Chinese and Japanese cooking, made from {#blank#}1{#/blank#} (special) treated rice. It is often presented in the form of a round cake, and is traditionally exchanged at the New Year.

Mochi is made by {#blank#}2{#/blank#} (put) sticky rice into water overnight, cooking it and pounding it into a sticky paste. The paste is made into shapes ranging from simple to complex rounds, some of {#blank#}3{#/blank#} are stuffed with sweet fillings. Mochi is often decorated with {#blank#}4{#/blank#} (flower) or fruits, especially when it is exchanged as {#blank#}5{#/blank#} gift at celebrations like birthdays and the New Year.

    Traditionally, wooden mortars (臼) and pestles (杵) {#blank#}6{#/blank#} (use) to pound mochi rice. Fresh mochi is usually cooked and served warm {#blank#}7{#/blank#} a variety of sauces. Steaming and boiling are both popular preparations in Japan, along with cooking. Fresh mochi is soft but it{#blank#}8{#/blank#} (hard) quickly. Prepacked mochi blocks, flattened and cut into square pieces or shaped into rounds, are available at grocery stores. Mochi can go bad easily, so it's {#blank#}9{#/blank#} (good) to cook soon than to keep it in your fridge.

    Hard mochi pieces can be cooked, deep-fried, boiled, and more. Cooked mochi is very sticky, so be careful not {#blank#}10{#/blank#} (choke) on it.
