Once my father and I went to see a circus(马戏团). A family was standing in front of us1  for tickets. The family had eight children. Their clothes were not expensive but they were clean. They were talking about the clowns(小丑) and elephants excitedly.

    "I want ten tickets, eight for children and two for adults(成人)."said the father to the ticket lady. The ticket lady told him the 2. When he heard that, the man couldn't believe his ears. He asked again," How much?" The ticket lady said again. The father looked 3 . Clearly, he didn't have 4money. My dad took a $ 20 bill and dropped it on the ground. Then he 5 the bill, and said to the man, "Sir, this fell out of your pocket." The man knew what was going on. He looked into my dad's eyes and took the bill." Thank you, thank you, Sir. This 6means a lot to me and my family." We didn't go to the circus that night, but we didn't feel sorry for it at all.   72    .

    It was a Sunday afternoon. It was 1 and Mike decided 2 swimming in the river. His 3, Jim, wanted to go with him.

    "Take him with you, Mike," said their father. "He will do 4 you say, I think."

    They 5 the river quickly. 6 people were swimming in it. Mike told Jim to play on the bank, and then he jumped 7 the river. About an hour later, Mike swam to the bank with a fish in his 8. Jim was very happy. He found a bottle(瓶) and put the fish in it.

    Jim did nothing but watch the fish that evening. Suddenly(突然) Mike heard Jim crying(哭) in the room. He ran to him and asked, "What's the matter(怎么了), Jim?"

    "The fish has died," Jim said. "I thought it was 9. So I took it out of the bottle and put it on the chair. I 10 wanted it to have a rest."

    I remember the first time I got on a horse. I was two years old and we were watching a friend of the family ride. My mom agreed to let me take a short ride around the ground with the friend and that was it' I became crazy about having a horse. From then on, I drove my parents mad beg­ging for a horse. Whenever I saw a horse, I would beg even harder.

    When I was four years old, problems appeared in my life. I had Selective Mutism (选择性缄默症). This is an unusual childhood disorder (失调) in which children stop speaking in certain social situations, many times at around the age of four. I spoke to my parents as usual, my brother and certain other people, but was silent at school and in social situations. I went days, weeks, months without a sound at school. At most, I might very quietly speak to a friend.

    My parents looked for a cure. One psychologist (心理医生) had an idea. Having discussed his plan with my parents in advance, one day I was asked by the psychologist what I wanted more than anything in the world. He explained that I was going to be given a chance to work for what I wanted. I couldn't believe my good luck, but I could not answer. I just stood there. Finally, I was allowed to whisper (低声说) the answer in my mother's ear. "A horse," was all I could say.

    I was to get a little horse, but before we could even start looking, I had to try to talk. I had a chart of weekly tasks I had to finish. I had to answer the phone five times every week, something I had never done before. I did everything that was asked of me and the day came when my parents found the perfect horse. His name was Sequoia, a strong little chestnut (栗子马). He was perfect, of course, and I fell in love immediately. It truly was a dream come true. When I was with Sequoia, I forgot all about my problems and felt strong and life.

    By connecting with them, I have learned to hug what I was once not able to do and I found my voice back.

{#blank#}1{#/blank#} ⑴The first thing to remember is that when a friend invites you over, you need to arrive on time. If your friend tells you to come "around 3:00", that means you can turn up a little bit after 3:00. But usually it is a good idea to arrive at the right time.

{#blank#}2{#/blank#} ⑵Often it is also nice to bring something to your friend's house. This could be a box of chocolate for you two to share, or maybe a movie that you can watch together. You can also bring some flowers. A little gift is a nice way to show your friend that you are excited to be at his house.

{#blank#}3{#/blank#} ⑶When you visit your friend's house, you may also meet his parents. You should tell them who you are and they may tell you their names, and then they may tell you to call them by their first names. Another way to show respect is to call them Madam or Sir.

{#blank#}4{#/blank#} ⑷As we all know, students should learn how to get on well with others. But in what ways? First of all, we should respect others. Everyone has their own way to do things, so we should understand each other. Besides, it is important for us to communicate with each other. What's more, we should be kind to others and offer necessary help to those who are in trouble.

{#blank#}5{#/blank#} ⑸Everybody has his parents. But not everybody gets on well with his parents. Well, first, we should respect our parents because they bring us up and care for us all the time. Second, we are supposed to do some housework at home. We should help clean the room, cook meals and so on. Third, we should care for them, have a talk with them about their work.

It seems that paleontology（古生物学） has nothing to do with fun. However，some online videos about it have become popular with young people. These videos are made by Fun Stuff，a science account（账户） on Bilibili. It has posted about 150 videos and most of them are for free. And these videos have been watched over 100 million times. 

The makers behind Fun Stuff are Tang Cheng and Cai Chunlin. They're a couple（夫妇） at the same university. Both of them studied science very hard and always discussed questions about science together. 

It all started on a small island in 2014，when Tang studied monkeys there. At the time，he started giving online classes to children. After one class，a student asked him what a cell（细胞） is. Then he decided to make more people fall in love with science. 

In 2018，Tang and Cai began to play some English science videos and share them on Bilibili. The next year，they began to make their own videos. They spent two months on their first video. It is about an amazing animal living in ancient times. In the video，Tang talks about the animal's look and habits and why it died out. The special and clear way to tell scientific facts soon made the video very popular. Since then，the couple has made lots of videos about ancient animals. 

"Fun Stuff has the interesting way to make science about the ancient world very interesting，" says a fan.
