There once was a forest filled with happy animals. One day a raccoon (浣熊) found some socks left behind by picnickers, and {#blank#}1{#/blank#}(decide) to wear them. They fitted so well, and felt so {#blank#}2{#/blank#}(comfort), that he kept them on. He spent his days {#blank#}3{#/blank#}(walk) through the forest in his new socks.

    Other animals became envious(嫉妒) of the raccoon's new look and followed his trend. First it was squirrels in {#blank#}4{#/blank#}(shirt), then rabbits {#blank#}5{#/blank#}hats on, and finally birds wearing underpants!

    Doctor Bear, the forest physician, disapproved and tried to warn the clothes-wearers. But no one listened. Instead, they urged him to follow the {#blank#}6{#/blank#}(late) trend too.

    Soon, the problems started. The squirrel caught his shirt on a branch and crashed to the ground. The rabbit tried entering his hole while wearing his hat and got stuck. Even the raccoon, thanks to his {#blank#}7{#/blank#}(bright) coloured socks, slipped into the river and almost died.

    When the {#blank#}8{#/blank#}(injure) animals came to see Doctor Bear, he told them, “Your clothes are killing you. You don't need {#blank#}9{#/blank#}.”

    Those {#blank#}10{#/blank#} listened to the doctor's advice finally understood they didn't need clothes. They'd only started wearing clothes to make others envy them.

    As is known to all, we live in a world of germs（细菌）. It is impossible to avoid exposure. Genetic makeups may give some people {#blank#}1{#/blank#} advantage over others. However, it does not stop people from becoming sick.

    All of us have been a victim of an {#blank#}2{#/blank#} (ill) at some point in our lives. Moreover, it is likely that we {#blank#}3{#/blank#} (get) sick again in the future. Our best chances of avoiding sickness {#blank#}4{#/blank#} (be) by exercising and employing good {#blank#}5{#/blank#} (habit).

    While good hygiene and exercise serve as obvious advice to most people, eating {#blank#}6{#/blank#} (healthy) is not always obvious. If you cannot define “healthy”, then your immune system will be happy {#blank#}7{#/blank#} (tell) you. The immune system is the foundation of our health. It works for us every day to keep us well. Ask {#blank#}8{#/blank#} (you): “Are you making its job easier {#blank#}9{#/blank#} harder?”

    Like any system, the immune system is not different. It has a tolerance too. If you eat unhealthily, your immune system will make you aware of it.

    Take a step in the right direction {#blank#}10{#/blank#} including some healthy food in your diet.

    A smiling face with tears, or “Tears of joy”, was chosen as the most popular emoji globally in 2016, according to a report{#blank#}1{#/blank#}（publish）by Chinese tech startup Kika.

    In 2015,emoji was the country's fastest-growing language in the UK and “Tears of joy”also became the Oxford English Dictionary's word of the year,{#blank#}2{#/blank#}（make）it popular on social media worldwide.

    As a language expert pointed out, the reasons{#blank#}3{#/blank#}this are as follows. For one thing, with the development of the Internet, especially the {#blank#}4{#/blank#}（popular）of smartphones, English alone is proving not enough to meet the needs of 21st-century digital communication. For{#blank#}5{#/blank#}emojis can offer greater freedom than verbal language. Meanwhile, compared with text messages, they are often more intuitive（直观的）and{#blank#}6{#/blank#}（simple）,which is also the reason why more and more People choose{#blank#}7{#/blank#}（express）their emotions and ideas by using emojis.

    Even if you don't send emojis yourself, you will{#blank#}8{#/blank#}（probable）receive them.

    However, nobody can definitely-tell {#blank#}9{#/blank#}emojis will finally come to look something more like traditional language that we understand and use daily some day or they are just in fashion for{#blank#}10{#/blank#}while like many things. “After all, it's an addition to language rather than a language itself,”Dr Drummond says.

    We think that life in Chinese high school is an adventure in which we have to survive mountains of homework and exams. Yet would it be {#blank#}1{#/blank#} (surprise) if I tell you that high school life in the US is almost as stressful and demanding as it is in China?

    In US high school, everything {#blank#}2{#/blank#} (record) and graded, including your grades on quizzes, tests and final examinations. Failing {#blank#}3{#/blank#} (turn) in your homework on time will directly affect your grade for a certain course. Perhaps contrary to {#blank#}4{#/blank#} we used to think of the US high school students, they pay great attention to their academic performance to try to get into distinguished university.{#blank#}5{#/blank#} they'll be disappointed after graduation from high school.

    Like university students, US high school students have the {#blank#}6{#/blank#} (free) to choose the courses that most interest {#blank#}7{#/blank#} (they). Even a 9th-grader can sit {#blank#}8{#/blank#} the same classroom as 12th-graders. But this also means he or she has to work very hard, because the teacher will not treat him or her {#blank#}9{#/blank#} (difference) just because he or she is a few years {#blank#}10{#/blank#} (young).
