Period One Listening and Speaking 1 Liangzhu culture: a glimpse into ancient China The Liangzhu culture, dating back 5,300 to 4,300 years, was an advanced civilization located in the Yangtze River Delta near modern Hangzhou. Known for its remarkable achievements, this culture offers key evidence supporting China's 5,000-year history. Building a large ancient city, the Liangzhu people created a well-organized society. The city centre included palaces, tombs, and altars, surrounded by massive walls and a complex water system. Using dams, canals, and reservoirs, they managed floods 主题素养积累 2 and irrigated rice fields, showing incredible engineering skills that still impress experts today. One of Liangzhu's most fascinating features is its jade (玉器) art. The people carved jade into objects like cong (tubes) and bi (disks), decorating them with patterns such as the “divine mask”. These items, which were buried in tombs of powerful leaders, symbolized both religious beliefs and social status. The famous King of Jade Cong, weighing 6.5 kilograms, is a masterpiece of ancient craftsmanship. 主题素养积累 Discovering the Liangzhu site has changed our understanding of Chinese history. In 2019, it became a UNESCO World Heritage Site, proving that advanced societies existed not only along the Yellow River but also in the Yangtze region. The ruins, including tools, pottery, and rice fields, reveal how these early people lived in harmony with nature. Today, Liangzhu teaches us about the creativity of Chinese ancestors. By studying their cities, art, and water systems, we learn how they laid the foundation for later Chinese culture, leaving a legacy (遗产) that continues to inspire the world.#1.5 主题素养积累 【主题词句背诵】 1.a glimpse into 对……的初步了解 2.(be) located in 位于;坐落于 3.craftsmanship n. 工艺；精湛技艺 4.in harmony with 与……和谐一致 5.lay the foundation for 为……奠定基础 主题素养积累 5 6.These items, which were buried in tombs of powerful leaders, symbolized both religious beliefs and social status. 这些被埋葬在权贵陵墓中的物品，既象征宗教信仰，也代表社会地 位。 7.In 2019, it became a UNESCO World Heritage Site, proving that advanced societies existed not only along the Yellow River but also in the Yangtze region. 2019年，它被联合国教科文组织列为世界遗产地，证明先进社会不 仅存在于黄河流域，还存在于长江地区。#7.1 主题素养积累 语言知识梳理 课后习题 7 1.creative adj.创造性的;有创造力的;有创意的 (1)create vt. 创造 (2)creatively adv. 创造性地;有创造力地 (3)creativity n. 创造力 语言知识梳理 8 【佳句背诵】 ［沪教必修二］ Sharing a creative spirit, Michelle and Jade decided to start their own fashion company. 米歇尔和杰德都富有创造力，于是决定创办自己的时尚公司。 语言知识梳理 9 【活学活用】 ◆单句填空 ①[2023·全国乙卷] Several studies have backed this up and found that indoor plants can improve _________(create), focus and memory. creativity ②[2022·新高考全国Ⅰ卷] I'm enjoying the ________(create) activities, and it feels great to have done something useful. ③If you want to succeed, you have to work hard and learn to think __________(creative). creative creatively 语言知识梳理 10 ◆完成句子 ④Congratulations to you again.

My grandparents insisted on repairing them, but I thought it a waste of time—why trouble with old buildings in a modern world? 1 2 3 4 5 6 7 8 课 后 习 题 42 However, I was asked to help document the process. I watched as elderly craftsmen carefully carved wooden patterns, their hands rough but steady, pausing now and then to compare them with old drawings to keep original styles. They explained that each detail carried stories of our ancestors' (祖先) lives. Villagers also joined in, bringing tools and sharing memories of growing up in the village. On a rainy afternoon, an elderly villager pointed to a cracked beam (横梁):“This is where my father taught me to fix 1 2 3 4 5 6 7 8 课 后 习 题 farm tools, and I played here with friends after school.” Her eyes shone with warm memories as she touched the worn wood gently. Suddenly, I realized the village wasn't just a group of buildings—it was a living record of our roots. As the repair work went on, many young people started visiting, attracted by the village's rich history and unique architecture shared online. Some even offered to help with digital documentation or designed cultural posters to promote it. The old village gradually came back to life, connecting the distance between age groups with new energy. 1 2 3 4 5 6 7 8 课 后 习 题 I once thought cultural heritage was something far away, preserved in museums. But this experience taught me it's right here, in the places we live and the stories we share. It's not about keeping things unchanged, but about passing on the values they stand for. Today, the ancient village stands proudly, a symbol of our cultural identity and a lively classroom for future generations. I understand now that protecting heritage is not a burden (负担), but a valuable gift we give to the future with love and responsibility.#7 1 2 3 4 5 6 7 8 课 后 习 题 【文章大意】本文是一篇记叙文。文章讲述了作者从最初认为修复 家乡古村落是浪费时间，到通过亲身参与和见证，最终领悟到这些 老建筑承载着家族记忆与文化根脉，其保护与传承具有重要意义。 1 2 3 4 5 6 7 8 课 后 习 题 46 ( )1.What did the author think of repairing the ancient village at first?

The local Hani ethnic group carved the terraces along the mountain slopes, passing down their agricultural practices through generations. Today, 305 canals crisscross the area, while canals channel water through the villages to irrigate (灌溉) the terraces. Locals regard the mountain forests as “sacred” (神圣的)， where there is a strict rule against cutting down trees. Ma Youde, a villager, says, “If anyone needs timber to build a 1 2 3 4 5 6 7 8 课 后 习 题 house, it must be allowed by the entire village.

The local government has carried out multiple measures, including village planning, ecological compensation (补偿) and a comprehensive monitoring system, to promote the high-level protection and utilization of the heritage. For example, the coming water system connectivity project will mix traditional irrigation wisdom with modern water technologies, developing local agriculture. 1 2 3 4 5 6 7 8 课 后 习 题 The terraces are not fields. They are an example of harmonious coexistence between human beings and nature, showing the ancient wisdom of adapting to and working with the natural environment.
