Many years ago, when I worked as a volunteer at Stanford Hospital, I got to know a little girl {#blank#}1{#/blank#}(name) Liz who was suffering from a rare and serious disease. Her only chance of recovery appeared to be a blood transfusion（输血）{#blank#}2{#/blank#}her 5-year-old brother,{#blank#}3{#/blank#} had miraculously survived the same disease and had developed the antibodies needed to fight the {#blank#}4{#/blank#}(ill).

    The doctor explained the situation to her little brother, and asked the boy if he would be willing to give his blood to his sister. I saw him hesitate for a moment {#blank#}5{#/blank#}taking a deep breath and saying, “Yes, I'll do it {#blank#}6{#/blank#}it can save Liz.”

    {#blank#}7{#/blank#} the transfusion progressed, he lay in bed next to his sister and smiled, as we all did, {#blank#}8{#/blank#}(see) the color returning to her cheeks. Then {#blank#}9{#/blank#}face grew pale and his smile faded. He looked up at the doctor and asked with a trembling voice, “Will I start to die right away?”

Being young, the boy had{#blank#}10{#/blank#}(understand) the doctor; he thought he was going to have to give his sister all of his blood.

    I was staying in Destin for a few days with my family. One morning, I got up early{#blank#}1{#/blank#}(go) for a walk on the beach. As I was walking, I noticed at least a hundred or more empty beer cans which{#blank#}2{#/blank#}(leave) in one concentrated area in front of a hotel. I was{#blank#}3{#/blank#}(fascinate) by the beach, woods and nature so I wanted to keep{#blank#}4{#/blank#}(they) clean. Naturally, I picked up a few to take to a nearby rubbish can. {#blank#}5{#/blank#}my way back to the hotel. I saw {#blank#}6{#/blank#}man walking down the beach with a rubbish bag picking up the cans. I helped him get the rest and walked back to my place, but I couldn't help {#blank#}7{#/blank#} (think) about that man and how we need more people like that in the world. It really gave me some {#blank#}8{#/blank#}(inspire).

    In the following days when I stayed in Destin, I always went for a walk with a rubbish bag. The rubbish bag was {#blank#}9{#/blank#}(total) full by the time I got back to my hotel. I did not want to get any thanks but I hoped {#blank#}10{#/blank#}I did could inspire someone to do the same as well.

    In recent years, learning Chinese{#blank#}1{#/blank#}(become) popular among people around the world. Last month, I received an email from my friend Jack in Canada. He said he was enthusiastic about China, and asked me to find him some books which {#blank#}2{#/blank#} (intend) for Chinese beginners, I was pleased to do such a favor. So I went from one bookstore to another,{#blank#}3{#/blank#} (hope) to find something suitable for him. Finally I selected a set of Chinese textbooks among a variety of similar ones.

    Living a life with meaning and purpose is the key to improving your psychological well-being. Your purpose doesn't{#blank#}1{#/blank#}(necessary), have to involve changing the world or finding a career {#blank#}2{#/blank#}(devote) to helping others. Instead, you might make it your purpose to be kind every day.

    {#blank#}3{#/blank#}you feel like your life lacks purpose, don't worry. There are many ways you can find purpose in life and build a life that has more meanings. You can begin by thinking about the legacy(遗赠) you would like to leave behind. Write down how you'd like to {#blank#}4{#/blank#}(remember) at the end: of your life, or think about the impact you want to leave {#blank#}5{#/blank#}the planet. Then, establish some{#blank#}6{#/blank#}(objective)that can help you reach those goals. {#blank#}7{#/blank#}(work) toward your goals will give you a reason, to get out of bed every day, beyond earning money.

    Thinking positively{#blank#}8{#/blank#}(improve) your psychological well-being. In turn, as your psychological well-being improves,{#blank#}9{#/blank#} becomes easier to think positively and feel good overall. Spend time thinking about some of the best memories - of your life. Whether it's a family vacation you went on 10 years ago or you won an award at work two years ago, recalling the {#blank#}10{#/blank#}(happy) times in your life can bring more positivity to your thinking.
