The Cheater

      Donald was not very good at math. He could not understand the teacher's explanations. “Never mind,”Donald told himself. “I'll cheat in the math exam, then I won't be in trouble.”

      The day of the exam came, and Donald sat next to Brian Smith, who always was at the top of the class in math. Donald carefully copied Brian's answers on to his own exam paper.

      The teacher collected the papers and graded (打分) them. Then she said, “Well, I've decided to give a prize to the student who got the highest grade. It's difficult for me to decide who to give the prize to, because two students, Donald and Brian, got the same grade.

“Let them share it,” one of the other students said. “I've thought about that,” the teacher said, “but I've decided to give the prize to Brian.” Donald stood up and said, “That's not fair. I got the same grade as Brian.”

“That's true,” the teacher said. “However, Brian's answer to Question 18 was ‘I don't know'. Yours was ‘Neither do I'.”

    One day, a farmer was walking along a road with his son Thomas. The father said, "Look! There's a horseshoe. Pick it up arid put it in your bag. "Thomas said." It isn't worth(值得) the trouble. "His father said nothing but he picked it up himself. When they got to a nearby town, they had a rest. There the farmer sold the horseshoe and with the few pennies he bought some cherries(樱桃).

    The father and the son continued their way. The sun was well up in the sky, and there wasn't a house or even a tree where they could have a rest. Thomas felt too thirsty(口渴的) to walk on. At the moment, his lather dropped a cherry on the ground and Thomas picked it up quickly and ate it. After a while, his father dropped another cherry and once again, his son picked it up and put it in his mouth.

    And so they went on. The old farmer dropped the cherries and the son picked them up. When Thomas had caught' up all the cherries, his father said to him," My dear son, if you had bent(弯腰) down in the beginning to pick up that horseshoe, you wouldn't have bent so many times for the cherries. Always remember this lesson：If someone don't worry about the little things, he will find it impossible for him to do the great things."

My name is Zhao Nan. I'm {#blank#}1{#/blank#} eleven-year-old schoolgirl. I'm from Zhejiang Province. I'm in Class 2, Grade 7 in Sunshine School. 

{#blank#}2{#/blank#}is the woman in the red jacket? She's my aunt, my {#blank#}3{#/blank#} (father) sister. She's in the same school as me. {#blank#}4{#/blank#}she's not a student. She works in {#blank#}5{#/blank#} (we) school library. She likes her job. She {#blank#}6{#/blank#} (think) it is interesting and relaxing. She can read {#blank#}7{#/blank#} (book) there, too. My aunt is good at English, but I am not. So she often helps me with my English. She likes {#blank#}8{#/blank#} (spell) English words with me. She teaches me to sing English songs, {#blank#}9{#/blank#}. She says, "Nannan, you can {#blank#}10{#/blank#} (do) well in English. "

Once upon a time, there were two fishermen called Luke and Jim. They were good at fishing. One day they went fishing by the lake. Jim {#blank#}1{#/blank#} fishing alone. Luke was an outgoing person who loved to make {#blank#}2{#/blank#} with different people.

When Luke found that some tourists at the lake couldn't catch any fish, he said to them,"I can teach you how to fish. If you catch ten fish, give me one fish as compensation (报酬). But {#blank#}3{#/blank#} you get fewer than ten, you don't need to give me anything." The tourists and Luke came to an agreement {#blank#}4{#/blank#}. After that, Luke started to {#blank#}5{#/blank#} them some fishing skills. After he finished teaching a {#blank#}6{#/blank#}, he went to teach another group. Hours later, he asked the tourists to give {#blank#}7{#/blank#} one fish for ten fish that they caught. At the end of the day, Luke got a full bucket of fish, and also made a lot of {#blank#}8{#/blank#} friends. The tourists regarded him as {#blank#}9{#/blank#} good teacher for teaching them how to fish.

As for Jim,{#blank#}10{#/blank#} fishing for a whole day alone, he looked into his fish bucket, and found he had far fewer fish than his friend. He felt very upset.

If we help others succeed, we will harvest(收获) both success and friends.

Young scientist Li Yuehua works at Zhejiang Lab(之江实验室) in Hangzhou, Zhejiang Province. There is something special about the lab— as Li enters it, she feels out of this world. It brings her to one of the earth's closest neighbors: Mars.

The lab simulates(模拟) the environment, such as the ground and light, on the red planet. In the lab, Li and her team develop and test AI technology to make future Mars rovers(火星车) smarter.

Zhurong, China's first Mars rover, got to Mars in 2021. As Zhurong moves on Mars, it sends information back to the earth. The ground team checks the information before it can move on. The process can take up to 40 minutes.

" Today's rovers are like babies. They can perceive what's around them but they're not able to understand them. Scientists on the earth must tell them how to communicate with the environment," said Li." We hope our AI technology will help Mars rovers learn about the environment and decide where to go on their own."

Li's team needed a better place to do that. Is there anywhere similar to Mars on the earth? The answer was found in the deep desert of Dunhuang, Gansu Province. The team went there in summer and soon started to work. However, it was so hot that several machines stopped working and some team members got sick. Although it was really hard, they didn't give up. Finally, the team developed a better technology.

" An important part of science is facing failure(失败)," Li said." It is like climbing. You face difficulties and try to solve them time after time."
