On Monday, World Health Organization (WHO) stated a plan to rid the world's food supply of trans fats（反式脂肪）. These unhealthy things have been related to many illnesses. WHO is a United Nations organization {#blank#}1{#/blank#} works to improve good health around the world. Its plan is called REPLACE. The step-by-step guide is designed {#blank#}2{#/blank#} (help) world governments remove trans fats {#blank#}3{#/blank#} their foods within the next five years.

    Trans fats {#blank#}4{#/blank#} (use) in baked goods and fried foods. Food companies use trans fats to keep foods for longer periods of time. But the things can be deadly. WHO says that{#blank#}5{#/blank#}(eat) foods with trans fats results in more than 500,000 deaths from heart disease every year. Trans fats are a harmful substances and can be removed {#blank#}6{#/blank#} (easy) without major cost and without any effect on the quality of the foods.

    Denmark {#blank#}7{#/blank#} (be) the first country to ban trans fats 15 years ago. The United States and 40 other {#blank#}8{#/blank#} (country) soon followed. “Why should our children have such {#blank#}9{#/blank#} unsafe substance in their foods?” Dr. Tedros Ghebreyesus asked in an interview. He is WHO's director-general. He said that the plan could “make food systems much {#blank#}10{#/blank#} (healthy) for future generations.”

    China is rich in tourist {#blank#}1{#/blank#} (attract). The long Chinese history and splendid culture {#blank#}2{#/blank#} (leave) it with many places of interest over the past centuries. The ancient Chinese laboring people created lots of world wonders, {#blank#}3{#/blank#} (include)the Great Wall. It is {#blank#}4{#/blank#} long that you can't see the end of it. From {#blank#}5{#/blank#} distance, it looks like a dragon on tops of mountain chains. Another {#blank#}6{#/blank#} (history) site in China is the Potala Palace, {#blank#}7{#/blank#} was once served {#blank#}8{#/blank#} the office building of Tibet local government. {#blank#}9{#/blank#} (fortunate), to help preserve the buildings, only a few people {#blank#}10{#/blank#} (admit) each day.

    It is quite clear that air planes provide {#blank#}1{#/blank#}efficient and convenient way to travel. Thanks to planes, the world we live in has become a {#blank#}2{#/blank#}(small) place. {#blank#}3{#/blank#} getting to somewhere by air can cause a lot of stress for people sometimes.

    There are many reasons {#blank#}4{#/blank#} an unpleasant journey, such as long lines at the airport or screaming kids who seat {#blank#}5{#/blank#}(them) behind you. However, recent {#blank#}6{#/blank#}（study) conducted by US travel platform Expedia have found that more than half of the people{#blank#}7{#/blank#}(survey) say what annoys them most are the passengers {#blank#}8{#/blank#} continually kick, bump or grab airplane seats.

    Why do they do that? Are they bored, nervous or just {#blank#}9{#/blank#}(complete) unaware? There is no sure answer to that question, it seems. According to Expedia, this behavior is likely{#blank#}10{#/blank#}(remain) one of the most common and hated parts of travelling by air.

    One morning, I was waiting at the bus stop, worried about {#blank#}1{#/blank#} (be) late for school. There were many people waiting at the bus stop, {#blank#}2{#/blank#} some of them looked very anxious and {#blank#}3{#/blank#} (disappoint).When the bus finally came, we all hurried on board. I got a place next {#blank#}4{#/blank#} the window, so I had a good view of the sidewalk. A boy on a bike {#blank#}5{#/blank#} (catch) my attention. He was riding beside the bus and waving his arms. I heard a passenger behind me shouting to the driver, but he refused {#blank#}6{#/blank#} (stop) until we reached the next stop. Still, the boy kept {#blank#}7{#/blank#} (ride). He was carrying something over his shoulder and shouting. Finally, when we came to the next stop, the boy ran up to the door of the bus. I heard an excited conversation. Then the driver stood up and asked, “Did anyone lose a suitcase at the last stop?” A woman on the bus shouted, “Oh, dear! It's {#blank#}8{#/blank#} (I).”She pushed her way to the driver and took the suitcase thankfully. Everyone on the bus began talking about {#blank#}9{#/blank#} the boy had done, and the crowd of strangers {#blank#}10{#/blank#} (sudden) became friendly to one another.

    Letters as a way of communication have long given way to phone calls and WeChat messages. But a TV show, LettersAlive, is helping bring this old way to keep in touch back {#blank#}1{#/blank#} the present.

    LettersAlive took {#blank#}2{#/blank#} (it) idea from a UK program, LettersLive, released in 2013. Both {#blank#}3{#/blank#} (show) feature famous actors and actresses, but there {#blank#}4{#/blank#} (be) no eye-catching visual effects or any regular showbiz(娱乐圈) activities. Instead, it's just a live event {#blank#}5{#/blank#} remarkable letters selected from a wide time span and a diverse range of subjects are read. There is, for example, a passionate letter from Huang Yongyu to playwright Cao Yu 30 years ago to criticize his lack of {#blank#}6{#/blank#} (create).

    Every letter is like a small piece of history. By hearing them being read, it's as if we are being sent back in time {#blank#}7{#/blank#} (experience) a moment that we would otherwise never have had the chance to.

    Compared to{#blank#}8{#/blank#} (publish) texts, letters also {#blank#}9{#/blank#} (natural) come with a personal touch. As well as celebrating the pain, joy, wisdom and humor, LettersAlive{#blank#}10{#/blank#} (commit) to promoting Chinese literature since first run.
