There was once a man who couldn't sleep well because he was afraid that there was a stranger under his bed. He thought that as soon as he went to sleep, the stranger would come out from the bed and rob(抢劫)him. He was worried that the stranger might even kill him!

    Every night, after he got into bed, the man had to get up again and looked under the bed. There was never anyone there, but as soon as he got back into bed, he had to get up and looked under the bed again. This went on for hours until at last he fell asleep from exhaustion(筋疲力尽).

    The time came for the man to get married. He didn't tell his wife about his fear but she soon found out because he kept her awake all night.

     “You must go to see a doctor,” she told him. “He will make you become well. You won't have such silly fear again.”

    The man did as his wife told him. He told the doctor his problem, and the doctor said, “You can be well again, but it will take about two years. You must come and see me three times a week. The cost for each visit will be $75.”

    The next day the man called the doctor and said, “ I won't need to visit you again. I'm well.”

    The doctor was amazed.(惊奇地) “How?” he asked. “Who made you get well?”

     “My wife did,”the man said. “When I told her how much I would have to pay you, she cut the legs off the bed.”

    As usual, Betty was sitting alone during break. As she sat, she heard a quiet "meow" nearby and found a little cat with a band showing the name "Lucky".

    She picked up the cat and went to ask her teacher if she could help the cat find his home as a class project.

    "Are you willing to organize this project?" Mrs. Smith asked. She had tried for months to get Betty to speak up in class, but Betty had stayed quiet. Maybe this was her chance to shine!

    Betty thought for a moment and then said, "Okay, we need to put up signs around the neighborhood and call the local newspaper." Tony also suggested that they call the Animals' Home. Soon students were busy drawing posters. Two students were making phone calls. Mrs. Smith was surprised to find Betty was so confident and really showed an ability to lead.

    Betty, however, was not thinking about being a leader or being shy. Her mind was on finding this lost cat's home.

    The two students making phone calls came back and announced, "The Animals' Home said that a family reported a lost cat named Lucky! They said they'd call the family to come and get him!" The class cheered. Ten minutes later, a woman showed up and said with joy, "Thank you for returning Lucky! He was very 'lucky' to have been found by such a caring group of students!"

    The class celebrated their success. Mrs. Smith celebrated, too. Betty sat comfortably with her classmates for the first time, laughing and joking. Mrs. Smith believed it was indeed lucky that Betty had found the cat—lucky for both of them!

    There is an old man in a house. In the house there are many mice. The old man has a cat. Every day the cat catches the mice and eats them. One day, the old mouse says "All mice must come to my room this evening. We must find a way to deal with the cat." All the mice come. Many mice speak but they don't know what to do. At last a young mouse stands up and says "We must put a bell on the cat. When the cat comes near we can hear the bell and run away. So the cat can't catch us." "Who can put the bell on the cat" asks the old mouse. But no one answers.

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. 

My best friend Jenny and I got to the mall for shopping. She held up a white sweater and nice skirt. "Do you like them?" she asked. 

"They're great, " I said. Jenny smiled and keep looking while I moved about, touching the beautiful clothes. "I'll try them on, " Jenny walked towards the dressing room. After a while, she came out in the outfit (一套衣服). She looked beautiful. 

Part of me wanted to say how good she looked, but another part stopped the words coming out. Jenny was in such good shape( 外 形 )that she'd look good in the outfit. Sometimes, I regretted(后悔)choosing a best friend who was so pretty. God, why can't I be the one with the rich parents and the great look? More and more, I was envious (妒忌的) of her. 

"Well, Tina, what do you think?" Jenny asked more than once. "Do you like it?"

The outfit looked great on her, but I lied, "Not really. I think you need something with more colors. "

"You think so?" Jenny said doubtfully. 

"Just believe me. We'll find something better, " I told her, pushing her back into the dressing room. "You just can't buy the first thing you see. " I did my best to get Jenny out of the store, away from that outfit. As we left, Jenny gave the outfit one last look. 

Just down the mall, we passed an ice-cream place. "My treat, " Jenny said, pulling out her wallet(钱包). 

I could never say no to ice-cream, so we got some and sat down at a table. As Jenny talked without stopping about a million things, I thought about my feelings toward her. Those feelings weren't kind. 

Sitting there, I began to see Jenny in a new light! Jenny was attractive (吸引人的) not just because of her good luck, but more because of her kindness. Treating me to ice-cream was far from her only show of generosity(大方). She also let me drive her car and borrow her clothes. 

Finishing our ice-cream, we headed for the next clothing store. "Look at that red sweater, " Jenny said when we passed the window. "It would be nice for you. Soon maybe you'll have enough by saving your pocket money to buy something like that. "

A few minutes earlier, all I had heard was about saving my pocket money. I had hated the fact that Jenny could ask her parents for anything, and they'd buy it for her. This time, however, I heard more. I heard the voice of someone who loved for who I was. So I needed to express( 表达)the same to her.
