The young artist and potter Allan had a wife and two fine sons. One night, his older son developed a severe stomachache. Neither Allan nor his wife took the condition very {#blank#}1{#/blank#} (serious), but the boy died suddenly that night.

    Knowing the death could {#blank#}2{#/blank#} (avoid) if he had only realized the seriousness of the situation, he always felt he was guilty. Worse still, his wife left him a short time later,{#blank#}3{#/blank#} (leave) him alone with his 6-year-old younger son. Unable to stand the hurt and pain, he turned to alcohol and became{#blank#}4{#/blank#} alcoholic.

    As the alcoholism {#blank#}5{#/blank#} (progress), Allan began to lose everything he possessed and finally died alone in a small bar. Hearing of his death, I thought, “{#blank#}6{#/blank#} a complete failure!”

    As time went by, I began to revalue my {#blank#}7{#/blank#} (early) rough judgment. I knew Allan's now adult son, Ernie, one of the kindest and most caring men I've ever known. I hadn't heard him talk much about his father. One day, I worked up my courage to ask him what {#blank#}8{#/blank#} earth his father had done so that he became such a special person. Ernie said quietly, “As a child until I left home at 18, Allan came into my room every night, gave me a kiss and said, ‘love you, son'.”

    Tears came to my eyes as I realized what I had been a fool to judge Allan {#blank#}9{#/blank#} a failure. He had not left any material{#blank#}10{#/blank#} (possess) behind. But he had been a kind loving father, and left behind his best love.

    As a listening child,I often heard{#blank#}1{#/blank#}(old) people say:"What dreams I had!"and"If only I had my life to live over."I{#blank#}2{#/blank#}(understand) that these men and women had missed the fullness of life somehow.

    But I wasn't going to miss it,I decided at the age of fourteen.In a slightly{#blank#}3{#/blank#}(use) copy book,I made a full list of what I wanted from life.I would be devoted to{#blank#}4{#/blank#}(realize) them one by one.{#blank#}5{#/blank#},as years went by,I was middle aged and alone.My children had left to make their own full life somewhere.I,too,didn't realize even half the amount {#blank#}6{#/blank#}what I had planned.One rainy night,I went to the bookstore to get a paperback book to read{#blank#}7{#/blank#}(me) to sleep on.I picked up an Emile Zola book,{#blank#}8{#/blank#}reminded me of something I had read long ago: Zola had said,“To have a child,to plant a tree,to write a book.”That,he said,was a full life!A great stillness grew about me as I realized I had a child,I'd planted a tree,and in fact,I'd even written a book.

    Eventually,I came to a clear{#blank#}9{#/blank#}(conclude),and it is{#blank#}10{#/blank#}university one: To live,to struggle,to be in love with life is fulfillment.

    Why do different people like different colors? The answer depends largely {#blank#}1{#/blank#} cultural values. To the Egyptians, green is a color {#blank#}2{#/blank#} stands for the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. During the Spring Festival in China, children {#blank#}3{#/blank#}(give) money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect {#blank#}4{#/blank#} (they) against evils.

    People's {#blank#}5{#/blank#}(choose) of colors is also influenced by their bodies' reactions toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally {#blank#}6{#/blank#} physically. When{#blank#}7{#/blank#}(work) in green environment, people have fewer stomach aches. Red can make a person's blood pressure{#blank#}8{#/blank#} (rise) and increase people's appetite. Many decorators will include different shades of red in the restaurant. And many commercial websites will have a red “Buy Now” button because red is a color that {#blank#}9{#/blank#}(easy) catches a person's eye. Unlike red, blue is believed to cause people to lose appetite. Therefore,{#blank#}10{#/blank#} you want to eat less, eating from blue plates can help.

    Savanna, 11, is possibly one of our next great experts of the heart disease. After visiting her Sunday school teacher, who was about to perform a heart {#blank#}1{#/blank#} (operate) at the hospital, Savanna's curiosity led towards a deep appreciation of the heart and its importance to the human body.

    Encouraged by her parents to research further matters of the heart, Savanna learned that one in three of her peers (同龄人) {#blank#}2{#/blank#} (be) suffering from childhood fatness, {#blank#}3{#/blank#} can lead to heart diseases. She began making YouTube videos sharing with the world ways to have a better health and create a happy, healthy heart.

    In 2016, Happy Heart Advice launched its Happy Heart Challenges, {#blank#}4{#/blank#} (provide) over 300 hundred children and families {#blank#}5{#/blank#} education and free resources for healthy living. In June, she {#blank#}6{#/blank#} (invite) as an important speaker at the 9th Biennial Obesity Conference where she shared valuable information on how to form healthy eating {#blank#}7{#/blank#} (habit) and everyday lifestyles, and was honored by the American Heart Association for her work and effects in the health community at such {#blank#}8{#/blank#} early age.

    She's currently working on an app that will make it {#blank#}9{#/blank#}(easy) for moms and families to shop for “Happy Heart-approved Food”. She makes it her life's goal {#blank#}10{#/blank#} (make) sure kids have healthy hearts.

    Why do many of us find {#blank#}1{#/blank#} difficult or impossible to fall asleep in a bed other than our own? Is it because the bed is {#blank#}2{#/blank#} (comfort)? According to a new study published in Current Biology, a significant reason is {#blank#}3{#/blank#} the scientists call "first night effect". They believe that one side of the brain acts as a "night watch" to warn us about potential dangers. It forces us {#blank#}4{#/blank#} (stay) awake on the first night in a new environment.

    For the study, 35 young volunteers {#blank#}5{#/blank#} (ask) to sleep in a sleep lab for several days. Meanwhile, researchers watched their brain activities.

    According to the researchers, on their first night, the left brains were {#blank#}6{#/blank#} (active) than the right brains and people had a hard time sleeping. However, left-brain activity decreased as days went by, {#blank#}7{#/blank#} (fall) even to the point of complete calm. In this process, the participants got an increasingly better sleep experience.

    The {#blank#}8{#/blank#} (finding) suggest that the different rhythms of the sides of the brain affect our sleep. When the two sides work {#blank#}9{#/blank#} (different), the balance between them is broken. Thus, the brain can't relax and is sensitive to anything strange in the surroundings, just {#blank#}10{#/blank#} it is in the daytime.
