How do you keep cool during summer? Air conditioners or electric fans are good 1 in modern society. But 2 that, people could only use fans.

    Over 3,000 years ago, fans began to 3 They were made of feathers (羽毛), bamboo or silk. They came in different 4 , including round and square.

    Later, with the invention of paper, folding(可折叠) paper fans became popular5 the Song Dynasty.  There are usually beautiful 6on fans. Some are landscapes (风景). Others are flowers and animals. Moreover, many great people including Su Dongpo, a poet of the Song Dynasty, and Tang Yin, a scholar (学者) and painter of the Ming Dynasty, once painted their masterpieces(杰作) on fans. This made fans not only 7 tools in daily life but also great artworks.

    So, with its value of beauty, people take fans as a 8 of status(地位). That's why in old China, emperors and scholars often held fans.

    Today, fans are also great collectors' items(藏品) and gifts. On the opening ceremony of the 2008 Beijing Olympic Games, folding fans were9 to leaders and officials (官员) of other countries. While they were 10 fans to get cool, they were also experiencing Chinese culture.

    The American Computer &. Robotics Museum was open to visitors in 1990 in Bozeman, Montana. At first it was planned to build in Princeton, New Jersey. The founders moved to Bozeman in 1988 and after looking at the area they decided to build the museum there. With Yellowstone National Park to the south and Glacier National Park to the northwest, the museum attracts thousands of visitors from all 50 states and over 50 countries. The American Computer &.

    In the universe, as we know, there is the Sun, the moon, the Earth and a good many stars. Through our geography lessons, we know the Earth goes around the Sun, and the moon goes around the Earth. We have day and night because the Earth keeps turning all the time. When our part of the Earth turns to the Sun, it is day. When our part of the Earth turns away from the Sun, it is night.

    Just because the moon is closer to the Earth than the Sun, it looks much bigger than the Sun. Big things will look smaller when they are farther, and small things also look bigger when they are nearer.

    The Sun is bright enough to give out very strong light. The moon can't give any light at all, but it looks quite bright, too. Why？In fact, the light from the moon comes from the Sun. The moon looks much bigger and brighter than the stars. But actually (事实上) the stars are much bigger and brighter than the moon. They look smaller than the moon also because they are farther away from the Earth.

    There are still many other planets in the universe. But of all these planets, only on Earth there are living things and people can only live on Earth, too. But at 9∶00 am on October 15th 2003,Chinese astronaut Yang Liwei was set up to space. He stayed there for 21 hours. It was the first time for Chinese to get into space.

Buma Musical Festival, started by a band named wild sounds in 2021 is to help Yi students to go to school. {#blank#}1{#/blank#}(最近), this band has received much attention on the Internet. 

During a trip to Meigu, a village in the {#blank#}2{#/blank#} (东北) of Yi autonomous prefecture, They met some local boys. "Their clothes were old and dirty, but their eyes were {#blank#}3{#/blank#}（充满的）of kindness and hope, " said Chisha, who started the band. "Students there have trouble {#blank#}4{#/blank#} (上学) school and can't get higher education. They even meet with varied kinds of {#blank#}5{#/blank#} (困难，困境) when they just want to get out of their hometown. "

Then the band had a {#blank#}6{#/blank#}（讨论） about the plans for how to turn music into a charitable cause (慈善事业). "You can't find anything more {#blank#}7{#/blank#} (惊人的) than music. " said Chisha. They started the musical festival to raise money for the students. The news {#blank#}8{#/blank#} （传播）quickly on the Internet. As a result, more singers joined in. Now People {#blank#}9{#/blank#} (考虑，认为) the band as one of the most influential bands all over China. 

Even though it was not easy at the beginning, Buma has helped over thirty Liangshan teenagers go to universities. In 2023, a medal was {#blank#}10{#/blank#} (呈递，授予) to the band because of their great work in helping children in poor areas. This year, at least another 10 Yi teenagers will get help. 

A little girl in Hangzhou who loves baking(烘焙) has become popular. She watched videos on the Internet to learn how to bake and set up a stall(货摊) for sale during the summer holiday in2024. She can get several hundred yuan a day from her sales. 

Feng does well in making cakes. From an early age, Feng often watched her parents cook in the kitchen. She truly started baking in her second grade. She watched baking videos on the Internet first. After that, she tried to improve her baking skills. Sometimes she could spend all day baking in the kitchen. 

In the summer holiday of 2024, Feng came up with the idea of setting up a stall outside to sell cakes. She could earn(赚) up to 500 yuan a day at most. Her mother mainly wanted to develop her daughter's skills. She didn't expect her daughter to have such strong hands-on and social skills. To her surprise, Feng Rui did everything from baking the cakes to selling them. Sometimes when the cakes were not sold out, Feng Rui gave them to cleaners and friends. Now, she begins to teach some children to bake. 

Feng Rui will keep studying baking. Her mother was proud of her and said, "Stick to what you love is a beautiful thing. I hope she has a colourful life. "
