Children across the world are taking pictures of their school meals. They are sending these pictures over the Internet to a young girl in Scotland. Then she shares the pictures and stories with people around the world.

    The girl's name is Martha. She likes to write. So Martha decided to start her own blog. Every day, Martha writes on the Internet about the meals she eats at school. She also takes pictures of the food.

    Martha is very honest about the food. She does not just describe the food. She judges (评价) the taste of the food. She also judges how healthy the food is. Sometimes she likes the food, and sometimes she does not. Now, other people send pictures to Martha. Students around the world share their pictures of their school food!

    Martha also started her blog for another important reason. She began to raise money for the organization (组织) Mary's Meals. Mary's Meals works in the East African country of Malawi . It provides food for children in schools. Martha encourages her readers to send money to Mary's Meals to help build a kitchen.

    Martha hoped to raise about 10,000 dollars. But the total reached 100,000 dollars and still keeps on growing!

    Martha's blog has also helped to improve meals at her school. Martha and her school friends found their meals improved since she started writing her blog.

    No one knows what will happen to Martha's blog in future. But already this girl has helped to change the eating experience of many children just by sharing pictures of her school meals.

    It was just three degrees above zero. "That's cold," thought Jane as she got ready to deliver her morning papers. Jane had 50 customers, and on cold mornings when she couldn't ride her bicycle, it took her more than an hour to make her rounds. As she collected her papers and put them into a big canvas bag, Jane regretted that she hadn't finished her math homework the night before. There was still time. She'd hurry with the papers and finish the math before breakfast.

    Less than an hour later, Jane was nearly finished. She had only five customers to go. She could then head for home to complete her math while her room fixed breakfast. As she rounded the corner, she saw a car in the middle of the street. It was Mr. Zimmerman, the elder man, who walked with a walking stick. His car was out of gas. "I'd like to help Mr. Zimmerman," thought Jane, "but if I do, I won't have time to do my homework." She hated to think what Mr. Roberts would say if she hadn't completed her papers.

    "It's his own fault for running out of gas," Jane talked to herself. "The station is only a half mile down the street. Surely Mr. Zimmerman can walk that far, even on a cold morning like this — can't he?" As she walked down the street, Jane wondered what to do.

How Do You Get to School Every Day? 

For most students in cities, it's 1 for them to get to school. They can walk or ride a bike to school. They can also get to school by bus or even by subway. It won't 2 them too long to get to school and go back home. 

But for some students in faraway villages, things are quite 3 . Life for them is hard. It's difficult for them to get to school every day. Usually they will spend a few 4 on the way. In one small village, there is a big river 5 the school and the village. The students can't get to school by boat because the river runs too 6 . They have to go on a ropeway to 7 the big river. Though it's dangerous, they are used to it and are not afraid. In their mind, going out to study is their 8 thing. 

But there are still many villagers who 9 leave their village. How they are looking forward to having a 10 ! I do hope one day their dream can come true. 

No one knows exactly when jazz was invented, or by whom. But it is {#blank#}1{#/blank#} (据说) that it began in the early 1900s. 

Jazz was a new kind of music for America and the world, and New Orleans was its birthplace. Who were the jazz pioneers? Most were blacks. This music was not {#blank#}2{#/blank#} (写) down, and at first only blacks played it. It was hard for white musicians to learn the new style. But soon they, too, were {#blank#}3{#/blank#} (弹奏) jazz. 

The popularity of this music {#blank#}4{#/blank#} (传播). From New Orleans, it traveled up the Mississippi to Chicago, then to Kansas City and New York. {#blank#}5{#/blank#} (在……以前) the time of the rise of America, there were many jazz musicians, both black and white. Many of them were famous. One man was {#blank#}6{#/blank#} (好) than the rest. His name was Louis Armstrong. 

Louis Armstrong was a born musician. He was not only talented but also hard- working. He also had a good sense of {#blank#}7{#/blank#} (幽默) and a big, good- nature d smile. These personal qualities were {#blank#}8{#/blank#} (有价值的) in his rise to fame. After he became famous, he traveled around the world. It seemed that everyone wanted to hear Louis play. 

But life was not always easy, especially at the beginning. Louis Armstrong was born in 1900 in New Orleans. His father {#blank#}9{#/blank#} (从不) went to school and his mother could hardly read. When Louis was still a kid, his parents separated, and Louis lived with his mother. How hard their life was can be imagined. And yet Louis smiled through everything. He later wrote, " My whole life has been happiness. Life was there for me and I accepted it. {#blank#}10{#/blank#} (无论什么) happened has been beautiful to me. I love everybody. "

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."

 In a small village, there is a girl named Lena. She is afraid of 1 in front of people. When she speaks, she is2 and her face turns red.

 One day, the water of 3 village dries up"One of us should go to the nearest town for help." a villager says.4 no one answers(回复) . Right at the moment, Lena 5 . She knows it is not just for herself, but for the village.

 Lena 6 to the town. When Lena gets there and faces the 7 , she feels nervous. She takes a deep breath(深呼吸) and 8 to tell the story of her village. Everyone in the 9 is moved (感动的) . At last, they decide to help the village. When Lena comes back with the10 news, all the villagers thank her again and again.

 Sometimes, the best way to solve a problem is to face it.
