A Thanksgiving Day story in the newspaper told of a school teacher {#blank#}1{#/blank#} asked her class of first graders to draw a picture of something they were thankful for. She {#blank#}2{#/blank#} (think) of how little these children from poor neighbourhood actually had to be thankful for. But she knew that most of them would draw pictures of turkeys or tables full {#blank#}3{#/blank#} food. The teacher was taken back with the picture Douglas handed in—a small childishly hand!

    But whose hand? The class was {#blank#}4{#/blank#} (puzzle) by the abstract drawing. “I think it must be the hand of God {#blank#}5{#/blank#} brings us food,” said one child, “a farmer,” said another, “because he feeds turkeys.” Finally, when the others were at work, the teacher {#blank#}6{#/blank#} (bend) over at Douglas' desk and asked whose hand it was. “It's your hand, Teacher,” he said in a low voice.

    She remembered that {#blank#}7{#/blank#} (frequent) at break she had taken Douglas, a small lonely child, by {#blank#}8{#/blank#} hand. She often did that with the {#blank#}9{#/blank#} (child). But it meant so much to Douglas. Perhaps this was everyone's Thanks-giving, not for the material things {#blank#}10{#/blank#} (give) to us but for the chance, in whatever small way, to give to others.

    My grandfather is a{#blank#}1{#/blank#} (retire) worker. On summer evenings, we often sat together outside the house {#blank#}2{#/blank#} (enjoy) the cool air. It was the time that he told me lots of his experiences before liberation.

    When my grandfather was fourteen years old, he worked in a coal mine. One day, when he and his two workmates were working in the tunnel, an{#blank#}3{#/blank#} (fortune) thing suddenly happened. A part of the tunnel fell down, and they were shut in it. They had no food {#blank#}4{#/blank#}(eat). When they were hungry, they only drank some water there. It was very cold in it. In order to keep warm, they hugged one another. In the darkness, they didn't know whether it was day{#blank#}5{#/blank#}night, they only felt they had stayed there for a very long time. They were too hungry to speak or move, and thought they{#blank#}6{#/blank#}(die). At last, the tunnel {#blank#}7{#/blank#}(dig) through. They were saved. They had been there for fourteen days! My grandfather said they weren't let out at once. If{#blank#}8{#/blank#}，they would have died. They were kept at the entrance to the tunnel {#blank#}9{#/blank#}it was very dim, and they were fed{#blank#}10{#/blank#}some thin porridge. After a day or two, they had recovered a bit, and they were helped out.

    One day, about ten years ago, while working at the cash register (收银机) in the gift shop at my University Museum of Natural History, I saw {#blank#}1{#/blank#} elderly couple come in {#blank#}2{#/blank#} a little girl in a wheelchair. As I looked closer at this girl, I found that she was {#blank#}3{#/blank#} (fix) on her chair. I then realized she had no arms {#blank#}4{#/blank#} legs, just a head, a neck and upper body, dressed in a little white skirt. As the couple wheeled her up to me, I turned my head toward the girl. When I took the money from her grandparents, I looked back at the girl, {#blank#}5{#/blank#} was giving me the most optimistic, {#blank#}6{#/blank#} (large) smile I had ever seen. All of a sudden, her handicap (缺陷) was gone and all I saw was this beautiful girl, {#blank#}7{#/blank#} smile just melted me and almost immediately gave me a {#blank#}8{#/blank#} (complete) new sense of what life is all about. She took me from a poor, unhappy college student and {#blank#}9{#/blank#} (bring) me into her world; a world of smiles, love and {#blank#}10{#/blank#} (warm). I'm a successful business man now and whenever I think about the troubles, I think about that little girl and the remarkable lesson about life that she taught me.

    I won't call myself the most accomplished person when it comes to {#blank#}1{#/blank#} (hold) chopsticks. In fact, I'm pretty sure that my technique looks clumsy at times. I tend to hold {#blank#}2{#/blank#} (I) in the middle, more beginner than expert.

    Still, since I eat almost every meal with the eating utensil(器皿)of choice in China it's not uncommon for a new friend or acquaintance to come to a simple {#blank#}3{#/blank#} (conclude) after observing me that my Chinese husband, Jun, must {#blank#}4{#/blank#} (show) me how to use them.

    They are wrong. I've used chopsticks ever since I was a teenager, a time when my sister and mother were both fond of Chinese cuisine and introduced me {#blank#}5{#/blank#} many new dishes, along with the {#blank#}6{#/blank#} (prefer) utensils in China. We always kept bamboo chopsticks along with our {#blank#}7{#/blank#} (knife), forks and spoons, ready for whenever we happened to have Chinese food for dinner. It was my closest family {#blank#}8{#/blank#} observed my first mistakes I made in using chopsticks.

    Plus, I lived over two years in China before Jun and I started dating and I {#blank#}9{#/blank#} (expect) to use chopsticks in almost every restaurant, stand and bar. Trust me, when you're hungry you figure out pretty fast what it takes to down(咽下) {#blank#}10{#/blank#} meal with these utensils.

    According to a study published in the journal Nature Sustainability in February, China and India are{#blank#}1{#/blank#}(main) responsible for making the Earth greener over the past two decades. Since 2000, the Earth's green leaf area{#blank#}2{#/blank#} (increase) by 5 percent, or over 5 million square kilometers. That's{#blank#}3{#/blank#}area equal to the total area of the Amazon rainforest. It is basically the result of many big tree-planting{#blank#}4{#/blank#}(project) in China and intensive agriculture(集约农业)in both countries.

    China and India contribute{#blank#}5{#/blank#}one third of the increasing greening, but contain only 9 percent of the planet's land area covered in vegetation(植被). China was the major contributor,{#blank#}6{#/blank#} (add) 25 percent to this increase, while India added 6.8 percent.

    Over the past few decades, China has made great efforts to green the land. In 1978, China {#blank#}7{#/blank#}(begin) a national-level forestation project-the Three North Shelterbelt Forest Program, also{#blank#}8{#/blank#}(know) as the “Great Green Wall”. The program has seen many trees planted in northern China to act as windbreaks (防风林). By the end of 2017, the forest coverage rate had reached 13.57 percent, compared to 5.05 percent 40 years ago.

    In the light of China's{#blank#}9{#/blank#}(succeed) in greening the desert, the UN believes the country is a good example for others{#blank#}10{#/blank#}(follow) and has lessons to share with the world.

    Should naps(小睡) actually {#blank#}1{#/blank#} (take) during the day? Well, we certainly know from {#blank#}2{#/blank#} (evident) in the sleep center and that of many other scientists that naps can give you benefits for both your brain {#blank#}3{#/blank#} your body. But naps can actually be {#blank#}4{#/blank#} double-edged sword because while we're awake during the day, we're building up sleepiness or sleep pressure. So when you try to fall asleep at night, you'll fall asleep quickly and then you'll stay asleep. And when we sleep, we actually release that sleepiness so that we wake up the next morning feeling {#blank#}5{#/blank#} (refresh).

    So if you take a nap during the day, especially if you take it too late in the afternoon, you will actually release some of that sleepiness and it will make it much {#blank#}6{#/blank#} (hard) to fall asleep and stay asleep soundly throughout the night. So the advice would be if you don't struggle with your sleep and you can nap{#blank#}7{#/blank#} (regular), then naps are just fine.

    But if you do find it difficult {#blank#}8{#/blank#} (fall) asleep or stay asleep at night, then you should avoid naps and try to build up that healthy sleepiness in the evening.

    The ideal nap depends on {#blank#}9{#/blank#} you want from that nap. Different stages of sleep actually give you different types of brain and body  {#blank#}10{#/blank#} (benefit).
