It's a fine day. The White family gets up at seven o'clock. They have breakfast at seven forty. And then they go to the park. They take a basket of food and a carpet (地毯). The park is not far from their home, so they ride bikes there. When they get to the park, it's half past eight. Mr. and Mrs. White are talking with each other. Their son, Ted, is playing with a ball. Their daughter, Jenny, is taking photos.

    After about an hour, Ted and Jenny sit down to relax. At that time, they see a squirrel eating a pine nut (松子) in a big tree. When they see the squirrel eating, they feel hungry. They go to help their parents take the food out of the basket. Ted has a hamburger. Hamburgers are his favorite food. Jenny has an apple. Mr. and Mrs. White have some bread. They have a great time in the park.

The erhu is a traditional Chinese musical instrument. It is the most popular of the huqin family. In the Song Dynasty, musicians began to use this type of huqin to perform different kinds of music, and it became quite a popular instrument. With the rise of some forms of folk art, the art of the erhu developed quickly during the Ming and Qing Dynasties. It became an important accompanying (伴奏) instrument in different folk music. Now it is used in both traditional and modern music. It has even become a solo (独奏的) instrument. One of the most famous musical pieces played on the erhu is Erquan Yingyue by Abing.

The erhu used to be mainly played by common people, As the playing skills were passed down by oral (口传) tradition, there are few written records about the erhu that can be found. To study the history and the development of the erhu, historians usually turn to ancient paintings, sculptures and murals (雕塑和璧画). The earliest pictures of this instrument were found in Yulin Caves and Eastern Thousand Buddha Caves in Gansu Province.

Because of so many people's effort, the erhu becomes more and more popular around the world. In fact, we can hear the familiar sound of the erhu in many Hollywood productions, such as Kungfu Panda in 2012 and most recently, the Oscar nominated(提名)film Up in the Air(《在云端》). When people watch these movies, they also enjoy the special music of the erhu. The erhu is also called "Chinese violin" by many westerners, but in many ways, they are quite different.

Back home, Qian at once {#blank#}1{#/blank#} helping China develop a space program. He started the Institute of Mechanics in Beijing, where he trained young scientists. He worked on many important space {#blank#}2{#/blank#}. In 1960, China's first rocket and first missile were launched(发射) {#blank#}3{#/blank#}. In 1970, China launched its first satellite. It is largely because of Qian's {#blank#}4{#/blank#} that China so quickly developed a space program, and became only the third country to send a manned rocket into space in

2003. 

Qian watched this rocket launch on television. He was by he will always be {#blank#}5{#/blank#} for his great contributions(贡献). He working so hard for his country, even through difficult times, helping develop the space program that pushed China into the future. 

"Our teas can help protect your teeth and your heart, possibly even helping to prevent cancer," said Luo Shengkai, one of four student hosts from Sichuan University High School. They 1 introduced three self-made health teas through a livestream (直播) on Douyin 2 March 27, 2022, and they 3 for several weeks by now. The livestream got over 60 4 likes and many online orders, with all profits (收入) going to local tea farmers.

"It's 5 first time we have sold tea online. We not only need to introduce 6 tea, but we also need to interact with the audience and answer their questions," said Luo. "We've learned a lot from the process, 7 it's tiring."

Luo is one of a group of students 8 take part in a two-year course on tea research. They learn about tea planting and picking, tea making, package design and marketing through research and fieldwork.

However, 9 a new and popular tea isn't easy. Luo and his team members 10 a tea to better protect students' eyesight. They first met with a professional from Chengdu University of Traditional Chinese Medicine and researched the properties (特性) of local tea. Then they learned 11 functions of ingredients such as goji berries (枸杞), mangosteen (山竹果) and cassia seed (决明子) and did experiments to find what would happen if they 12 all together. They ended up with a cassia seed tea and then added 13 ingredients based on people's feedback.

"Through the tea course, students 14 learn how to be creative and improve their hands-on skills. They also learn to respect tea workers and how to contribute to rural vitalization (乡村振兴). That's 15 our educational means." said Mi Yunlin, the principal of the school.
