Do you believe that we can have an important influence on anyone we meet? The right words at just the right time could 1someone's life.

    When I was 3 years old, my parents discovered I was2. After asking many doctors and parents of other deaf children, they decided not to put me in a special school. Although I seemed outgoing, my self-esteem（自尊心）was quite low. On my first day at school, the other kids3 me because of my hearing aid andthe way I talked. I was hurt deeply and I saw myself as a(n)4kid.

    Mrs. Green, my5,changed all of that with a simple three-word phrase. One morning, she asked the class a question. Sitting at my desk silently, I 6 herlips（嘴唇）and raised my hand right away. She called on mein front of the blackboard. I took a deep breath and7 answered Mrs. Green's question.

    I will8forget what happened next. Mrs. Green pointed directly at me. With sparkling （闪光的）eyes and a big smile she cried:         "That's right, Ben!"

    For the first time in my young life, my confidence（自信）rose. At that moment, I decided that no matter how many9 I may face, I can overcome（克服）them. Thanks to those three 10 words, my whole life changed from that moment.

    Years ago, I celebrated my 40^th birthday with friends in a 1 restaurant. Many arrived earlier and waited outside the restaurant, as I was on the roadside, a homeless man came near to me and 2money. I let him know I didn't have any cash (现金)with me. With a quiet smile on his face, he moved on.

    Just then a friend arrived and called out, "Happy Birthday!" Hearing this, the man turned and asked, "Hey, man, it's your birthday？""Yes, "I said. He walked 3, smiled and said, "Happy Birthday!" I was not 4 ready for what happened next. He took out a dollar from his dirty bag, and gave it to me, saying, "Here man, take this. Happy Birthday! "That's 5. I expected he was making a joke!

    Although I 6 deeply by his generosity (慷慨), accepting money from a homeless man was embarrassing for me. I felt very uncomfortable. 7I replied, "Thanks, but…"Looking directly into my eyes, he said, "God, so good to me Every night, I always end up with a place to sleep and enough food to eat. Please take this. "I held out my hand-8 thinking twice, saying," thank you"

    This was one of my9 life lessons— however poor we may feel, we always have something valuable to share with others. From then on I often helped people in need and treated everyone with kindness and 10, spreading love and joy everywhere I went.

Nature was Chen Rui's "childhood home". The 37-year-old researcher at the Chinese Academy of Sciences' Institute of Zoology was not able to talk until he was 4 years old because of the way his brain processes sensory (感官) information. 

This made him "strange" in some people's minds. So, he didn't have friends who were around his age, which led him to turn his attention to nonhuman things around him. He became enraptured by the world of insects. "The happiest time of my childhood was in the farm fields," says Chen. "I squatted there, observing the actions of insects. I had so many questions about their activities and was full of curiosity about this world." These experiences planted a seed in his heart. 

Many years later, he's an expert in life-science research. He has visited the Amazon rainforest several times, and has found around 100 new species (物种), many of which are named after him. 

"I was a child who was ‘cured (治愈)' by nature," he says. "I wanted to grow up to share the power of nature with more young people and to popularize understanding of animals, including insects. I wanted to start classes to bring children to learn in the open air and experience the gifts nature gives." These led him to recently publish the popular science book, Du Chong Ji (Reading About Insects) 

"Insects were the earliest creatures that could fly and feed themselves by farming. They have survived three mass extinctions (大规模灭绝). No other living things have won such victories." He hopes that people will learn and draw inspiration from the "superpowers" of insects and use it to improve their own lives. 

Every year, Australia hosts a 543. 7-mile-long ultra-marathon(超级马拉松) race. 

In 1983, a potato farmer named Cliff Young showed up at the start of the race. People {#blank#}1{#/blank#}(意识到) that he was 61 years old and the race was dangerous for him. Cliff Young might {#blank#}2{#/blank#}(死) of tiredness, so some people tried to stop him. 

However, Cliff Young surprised everyone with an amazing {#blank#}3{#/blank#}(胜利). He not only won the race, but {#blank#}4{#/blank#}(设法完成) to break the race record. 

So how did Cliff Young make it? Well, he {#blank#}5{#/blank#}(继续) running throughout the night while other runners were {#blank#}6{#/blank#}(休息). He really had a very strong {#blank#}7{#/blank#}(意志). 

When Cliff Young was awarded the winning prize of $10, 000, he said he {#blank#}8{#/blank#}(实在；的确) didn't know there was a prize. He gave away his prize money to the rest of the runners after him. 

After the win, Cliff Young {#blank#}9{#/blank#}(参加) many ultra- marathon races to raise money for homeless children. His running style which is still popular {#blank#}10{#/blank#}(在国外) is called " The Cliff Shuffle". 

How tall is a tree? Usually trees in parks are over a few metres tall. But in Xizang, a fir(冷杉) is about 83. 4m tall! It is the tallest tree in China until 2022. The tree is about 380 years old. It is still growing well. 

Chinese scientists measured it in August. How did they measure such a tall tree? Scientists climbed up to the top of the tree. It took them about seven to eight hours to get to the top. They put down a 100-metre-long metal tape(金属卷尺) to the ground. Scientists measured this tree with a drone(无人机) in May. They said it was 83. 2m at that time. This time, they measured the tree more carefully and found it was 83. 4m. 

Scientists used a drone to take photos of the tree. The drone took three to six photos every few metres. It got over 160 photos. Putting them together, scientists got a full-size photo of the tree!
