Bob was only seven years old. One night Bob was at home {#blank#}1{#/blank#} while his parents were out for a party. He had often stayed alone before, so he wasn't afraid. As he waited for his parents to {#blank#}2{#/blank#} home, he watched a film on TV. His eyes became heavier and heavier as time {#blank#}3{#/blank#} by.

      Suddenly Bob's eyes opened wide-what was the {#blank#}4{#/blank#} in the next room? Bob heard the window being opened slowly. For a minute, Bob was so {#blank#}5{#/blank#} that he could not move, and his body felt like ice. He knew that he couldn't lose his head (惊慌失措) and began to think of the things he could do. Again he heard the sound of someone trying to climb into his home {#blank#}6{#/blank#} the window.

      Bob's drums were standing in the corner near the TV. "Wait, {#blank#}7{#/blank#} there is something I can do," thought Bob. He {#blank#}8{#/blank#} on his drums as hard as he could. The sound was so terrible that Bob {#blank#}9{#/blank#} even himself. He also surprised the man in the window, who {#blank#}10{#/blank#} away as fast as possible. How clever he was!

    Once upon a time, there was a rich man and a poor tailor(裁缝). They lived in {#blank#}1{#/blank#}same house. The rich man lived upstairs and the poor{#blank#}2{#/blank#}lived downstairs. The tailor liked to sing when he made clothes. He sang one {#blank#}3{#/blank#} after another. But the rich man liked to sleep a lot, and he couldn't get to sleep because of the singing. He felt very {#blank#}4{#/blank#}.

    One day, the rich man said, "Tailor, I will give you a bag full of {#blank#}5{#/blank#}every day if you stop singing. "Fine, "said the tailor. And so the tailor {#blank#}6{#/blank#}singing and became richer and richer. But the more money he got from the rich man, the {#blank#}7{#/blank#}he became, because he wanted very much to sing again.

    At last he brought all his money {#blank#}8{#/blank#}to the rich man. "Here, "he said, "take your money back. I won't be happy {#blank#}9{#/blank#} I can't sing. "He gave the money back to the rich man and went away singing. {#blank#}10{#/blank#}sang and sang and was happier than before.

An old man was sitting on the sofa with Mike, his 45-year-old son. Suddenly a dove (鸽子) landed on the ground. 

The father asked his son, "What is this?"

The son replied, "It is a dove."

After a few minutes, the father asked his son for the second time, "What is this?"

The son said, "Father, I have just told you. It's a dove."

After a little while, the old father asked his son for the third time, "What is this?"

This time Mike could not control his anger and shouted, "It's a dove, a dove. Why do you keep asking me the same question again and again? I have told you so many times 'IT IS A DOVE!' Don't you understand this?"

The old man silently took out an old diary, turned to a page and showed it to Mike. Though a little impatient (不耐烦), Mike began to read it. 

"Today my little son aged three was sitting with me on the sofa, when a dove landed on the ground, and my son asked me what it was. I smiled at him, said it was a dove and hugged (拥抱) him. After a while Mike asked me again and I did the same. Pointing to the same dove, little Mike asked me what it was 23 times and I kept on answering his question and hugging him every time."

Something gently touched Mike's heart. His face turned red with shame for being so impatient to his father and he hugged him tightly (紧紧地). 

Your parents have given you many things in their lifetime, but you may not realize that until they are gone. 

Martin is a boy full of questions. He asks questions all day long and{#blank#}1{#/blank#}(hope) to get the answers at once. 

One morning, he looked up at the sky{#blank#}2{#/blank#}asked, "What makes the day? What makes the night? And how?"

"The earth travels around the sun. It turns to face the sun to make the day and turns away from the sun to make the night, "said{#blank#}3{#/blank#}(he) father. "Now please, will you go and play?

But the boy didn't want{#blank#}4{#/blank#}(play). He looked up, down, and all around, and said, I can't feel the earth turning. Why?"

"The earth is so big. We're too small to feel it turn. "Dad replied in a much{#blank#}5{#/blank#}(loud)voice. "Now please, will you go and play{#blank#}6{#/blank#}a moment?"

Martin tried. He played with some{#blank#}7{#/blank#}(toy), and then studied the pictures of the sun and the earth, but questions were still everywhere!

At bedtime, while his mother{#blank#}8{#/blank#}(tell) him a story, Martin couldn't help asking. "{#blank#}9{#/blank#} can see the sun now?

"People on the other side of the earth, "Mom answered gently. "Hmm, "she thought, "maybe he will become{#blank#}10{#/blank#}great scientist in the future. "

Martin lay in his bed and kept on thinking about the sun, the earth, the moon and the stars. 

 Guo Guangpu, a university professor, can be a bit odd outside the classroom, especially when he is seen sniffing(闻) bird droppings, or even pretending to eat them for dramatic effect.

 This dramatic way of teaching has proved to be effective. To date, Guo has made more than  100 short science videos about animals and plants, as well as eco logy systems. People can find information on a wide range of interesting natural phenomena(现象) in Guo's educational videos on the popular short video- sharing platform Douyin.

 His followers have watched his trips to learn about unusual knowledge. For example, they can see lychee in Dongguan of Guangdong province, Asiatic toad (蟾蜍) in Zhejiang province, and weird fruits of various shapes and sizes in Yunnan province.

" Science videos are not easy to make. You have to be professional as well as lively and interesting. Only in this way can people with different levels of knowledge understand," Guo says. Therefore, he needs to look up plenty of information to make sure that there are no mistakes in his videos. While presenting the knowledge, he also tries his best to deliver the information in plain words.

 As a result, his efforts have attracted more than 14,000 followers since March. Some of his videos have received as many as 17,000 likes.

" With the help of Professor Guo,I am able to appreciate the beautiful land across the country even without leaving home," says Ren Jiaxi, one of Guo's Douyi n followers." His video encourages my interest in learning," Ren adds.

One very famous symbol in American culture is a cartoon. We all know and love the black mouse {#blank#}1{#/blank#} two large round ears — Mickey Mouse. Over 90 years ago, he first {#blank#}2{#/blank#}(appear) in the cartoon Steamboat Willie. When this cartoon came out in New York on November 18, 1928, it was the {#blank#}3{#/blank#}(one) cartoon with sound and music. 

Some people might ask why this cartoon animal became so popular. One of the main {#blank#}4{#/blank#}(reason) is that Mickey was like an ordinary man, but he always tried to face any danger. In {#blank#}5{#/blank#}(he) early films, Mickey was unlucky and had many problems. {#blank#}6{#/blank#}, he was always ready to try his best. People went to the cinema to see {#blank#}7{#/blank#} "little man" win. Most of them wanted to be like Mickey.

On November 18, 1978, Mickey became the first cartoon character {#blank#}8{#/blank#}(have) a star on the Hollywood Walk of Fame. Today's cartoons are usually not so simple {#blank#}9{#/blank#} little Mickey Mouse, but everyone still knows and loves him. Who has a pair of ears {#blank#}10{#/blank#}(famous) than Mickey's?
