When I met Larry, my husband-to-be, he came with an eighteen-month-old daughter, Mckenna, and a four-year-old son, Lorin. I quickly {#blank#}1{#/blank#} (fall) in love with Lorin and Mckenna, {#blank#}2{#/blank#} the children's mother, Dia, was a different story.

    There was a feeling of hostility（敌意）between us. Sometimes I wished that she would simply disappear. Then the children could stay with us— {#blank#}3{#/blank#} (true) be mine—and we could be a “real” family.

    Years {#blank#}4{#/blank#} (pass) by, something changed. I began to enjoy talking to Dia about the Kids. And she realized that there were very few people in the world {#blank#}5{#/blank#} were as interested in her children {#blank#}6{#/blank#} I was. One year, Dia sent me a Mother's Day card thanking me for “co-mothering” her children.

    Thank you, Dia, for being kind enough {#blank#}7{#/blank#} (share) your children with me. Thank you for making Christmas morning {#blank#}8{#/blank#} exciting and warm time, so the children never had to feel sad on these important days. We all could sit around the tree. There {#blank#}9{#/blank#} were, you and your husband, Larry and me, the kids ... and {#blank#}10{#/blank#} (surprise), I felt at home.

    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 with a little girl in a wheelchair. As I looked {#blank#}2{#/blank#}(close) at this girl, I found that she was fixed on her chair. I then realized she had no arms or legs, just a head, a neck and upper body,{#blank#}3{#/blank#} (dress) 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 {#blank#}4{#/blank#} the girl, who was giving me the most optimistic, largest smile I had ever seen. All of a sudden, her handicap (障碍) was gone and all I saw was this beautiful girl,{#blank#}5{#/blank#}smile just melted me {#blank#}6{#/blank#}almost instantly gave me a completely new sense of {#blank#}7{#/blank#}life is all about. She took me from a poor, unhappy college student and {#blank#}8{#/blank#}(bring) me into her world; a world of smiles, love and {#blank#}9{#/blank#}(warm). I'm a successful business man now and whenever I think about the troubles of the world, I think about that little girl and the remarkable (非凡的) lesson about life that she taught {#blank#}10{#/blank#}.

    The Great Wall of China is more than 6,000 kilometres long. It winds {#blank#}1{#/blank#} (it) way from west to east, across deserts, over mountains, through valleys{#blank#}2{#/blank#}at last it reaches the sea. The Great Wall has a history of over twenty centuries. The first part of it {#blank#}3{#/blank#}(build) during the Spring and Autumn period. During the Qin Dynasty, {#blank#}4{#/blank#}(keep) the enemy out of his empire, Emperor Qin Shi Huang had all the walls {#blank#}5{#/blank#}(join) up. Thus, the Great Wall came into being. The Great Wall is wide enough at {#blank#}6{#/blank#}top for five horses or ten men to walk side by side. Along the wall are watchtowers, {#blank#}7{#/blank#}soldiers used to keep watch. Fires were lit on the towers as a {#blank#}8{#/blank#} (warn) when the enemy came.

    It was {#blank#}9{#/blank#}(extreme)difficult to build such a wall in the ancient days without any modern machines. All the work was done {#blank#}10{#/blank#}hand. Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth, but of the flesh and blood of millions of men.

    The "One Belt One Road" strategy(策略) proposed by President Xi Jinping has drawn public attention to {#blank#}1{#/blank#} oldest and longest trade route-Silk Road．The term in a narrow sense refers to an ancient overland trade route {#blank#}2{#/blank#} （form） in the Western Han Dynasty．This route stretched 4, 350 miles from Chang's an to western China，central Asia and even to Europe, {#blank#}3{#/blank#} （enable） theses regions to have better communications in diplomacy（外交），business and culture．

    China was the first country in the world to breed silkworms and produce silk fabric．This craft skill reached a {#blank#}4{#/blank#} （fair） advanced level in the Zhou Dynasty．As a major export to Europe， "silk" was used to name this great route by a German geographer．China's silk{#blank#}5{#/blank#} （introduce） into western countries through this old trade route．People were {#blank#}6{#/blank#} （familiar）with his product at the beginning，and made many guesses at {#blank#}7{#/blank#} it was produced．According to the record， the idea that silk was picked from trees was widely accepted by folks in Europe．

    {#blank#}8{#/blank#} （garment服装）made of this fabric were always best sellers，and were considered a social status symbol．Ever the gorgeous Egyptian queen，Cleopatra，was also a big fan of the silk．This fascination led {#blank#}9{#/blank#} an increasing demand for this product，and promoted the {#blank#}10{#/blank#}（develop） of this trading route．

    Everyone needs to know how to prevent a fire. It is also important to know what to do when it {#blank#}1{#/blank#}（break）out .

    Every year, over 11, 000 people {#blank#}2{#/blank#}（kill）or injured in house fires. These fires could have been avoided. Smokers who are {#blank#}3{#/blank#}（care）cause about 200 deaths and over 6,000 fires. More than half of those {#blank#}4{#/blank#} die in fires are poisoned or harmed by smoke.

    If fire happens, do not attempt to fight the fire unless it is small. Try putting out a small fire with water. If {#blank#}5{#/blank#} fire has spread or if the flames are more than 20 inches high, shut the door on it. Warn everyone else in the building and tell them to get out. You should leave and dial 119for the fire department.

    Before {#blank#}6{#/blank#}（go）into a room, check the door. If the handle or the door is hot, do not open it! Instead, put clothing or a wet towel at the bottom of it to keep smoke out. If the door is not hot, open it {#blank#}7{#/blank#}（slow）. If there's a rush of smoke or heat, close it again and shout to warn {#blank#}8{#/blank#}（other）in side.

    Now open the window and shout “Fire!”. See whether you can drop safely to the ground. Use this {#blank#}9{#/blank#} your escape course if you can. If you are not on ground level, break your fall by pushing a mat out first. Lower yourself at arm's {#blank#}10{#/blank#}（long）before dropping. Once outside, stay outside and make sure the fire department is called.

    Do you live in a city? You've probably noticed how noisy and crowded life in a city can be. {#blank#}1{#/blank#} if you could live next to a calm lake instead?

    As it turns out, {#blank#}2{#/blank#} (live) near bodies of water – lakes, rivers, ponds, even oceans – can help us feel both happier and healthier. Those who live less than a kilometer from the coast are around 22 percent less likely {#blank#}3{#/blank#} (have) mental health problems than those who live 50 kilometers or more away, according to a study by researchers from the University of Exeter, UK. People who visit the coast at least twice a week tend to experience {#blank#}4{#/blank#} (good) general and mental health as well.

    So how does "blue space" make us feel better? For one thing, aquatic environments tend to have less pollution and more sunlight, both of {#blank#}5{#/blank#} linked to better mental and physical health. People who get more sun tend to be happier than those who do not.

    There's also the air above {#blank#}6{#/blank#} sea. After spending time near the ocean, you might find that you feel more relaxed than usual. This is {#blank#}7{#/blank#} sea air is charged with negative ions (负离子). These ions balance our levels of serotonin (血清素), a chemical that affects our moods. With {#blank#}8{#/blank#} (balance) serotonin levels, we feel more calm and relaxed, according to Daily Mail.

    Finally, people who live near water tend to be more {#blank#}9{#/blank#} (physical) active, according to the Guardian. Water sports like swimming and rowing can help us stay {#blank#}10{#/blank#} shape, which in turn keeps us healthy.
