     Hello, I'm Tom. I remember at one time, when we were running on the playground, I was too tired to go on. As I wanted to give up, some of my classmates cheered me up. My classmates' encouragements helped me finish the run. I'll never forget it.

     Hello, I'm Mary. When I was in Grade Two, I didn't prepare well for an English contest. I said sorry to my teacher. He said: “Any opportunity is important. You should never give it up easily.” Later on, I made good use of every opportunity. I'll never forget him.

     Hi, I'm Lucy. The time I traveled to Qingdao with my classmates was the most unforgettable experience. We swam in the sea and caught crabs (螃蟹) on the beach. We played games and enjoyed the beautiful scenery. I will never forget that trip.

     Hi, I'm Jim. I took part in the red song competition with my classmates last year. Every day, we rehearsed(排练) very hard in order to get a good result. Because of our hard work, we achieved a good result in the competition.

    The largest animal living on the earth is the blue whale. It weighs about 80 tons—more than 24 elephants. It is more than 30 metres long. A newborn baby whale weighs as heavy as a big elephant.

    Cats can survive(存活) when they fall down from a very high place because they can keep their bodies safe. One cat fell 32 floors onto the street, but it was just hurt a little.

    A bear can run as fast as a horse.

    A newborn panda is smaller than a mouse, and weighs about 100 grams.

    Elephants are the most careful animals in their love. A male elephant may show his love to a lady for up to three years until the lady accepts his love. They often show their love by touching each other's body.

    Usually, wolves don't attack(攻击) people. And wolves don't usually go together, but they may do this in winter.

    In China, learning some safety knowledge(知识) is becoming more and more important now. How should you keep yourself safe？

    {#blank#}1{#/blank#}

    At school：

    When students around you begin to push, try to hold onto something, or stay in a safer corner. {#blank#}2{#/blank#}

    On your way home or to school：

    Wait for the green traffic light. {#blank#}3{#/blank#} Wear clothes in bright colors, so the drivers can see you easily.

    {#blank#}4{#/blank#}：

    Stay calm and leave quickly. To keep clear of smoke (烟雾),use a piece of wet cloth to cover your mouth and nose.

    For riding on the escalator（自动扶梯）：

    {#blank#}5{#/blank#} You should hold onto handrails（扶手） and stand on the right side of the escalator, because right arms are stronger.

    Baozi is one of the common Chinese foods for breakfast. Who would have thought that this simple meal would become a leading character in a film, and even win an Oscar?

    On February 24, 2019, the short film Bao won the Oscar for Best Animated Short Film. In the film, a small baozi comes to life and becomes the "son" of a lonely Chinese woman in an immigrant(移民) family in Canada.

    Domee Shi, Pixar's first Chinese-canadian woman director, got the idea from her own experience. When Shi grew up, she was busy working and spent little time with her mother.

    Bao explores the life of an empty-nest Chinese Canadian mother who feels lonely after her son leaves home to go for his own life.

    In the film, many details show the way the Chinese woman loves her "son". She prepares delicious food, cleans up the house carefully and always buys him snacks. These details are true to the strong and protective love of Chinese parents for their children

    Traditionally, Chinese parents don't say 'I love you' to their kids. They express it with food or by fussing(小题大做) over them. "I didn't use dialogue in the film because I wanted it to be a story that spoke to everyone around the world." said Shi at an interview.

    Moreover, this film can serve as a bridge to help parents and children better understand each other and learn how to express love.

    Everyone loves chocolate- kids and grown-ups alike, and no matter what your age is, you are sure to enjoy learning more about chocolate. Read on to learn some fun facts.

    All the chocolate we eat comes from a special plant- the cacao tree. These trees produce a special kind of seeds. {#blank#}1{#/blank#} Then they are used to make chocolate.

    {#blank#}2{#/blank#} So they grow best when under the branches(树枝) of taller trees in the forest. They won't begin to bear fruit, however, until they are at least three to five years old. Cacao trees produce beautiful flowers all the year round. {#blank#}3{#/blank#} A kind of small flies pollinate(对......授粉) these small flowers. These flies are so small that they easily stand on the head of a needle(针状物). They beat their wings very fast—1, 000 beats a second! {#blank#}4{#/blank#} A cacao pod(可可果) has about 30—50 seeds. This is enough to make about seven milk chocolate candy bars!
