    Every April, there is a special day when people remember and honor their ancestors (祖先). It is called Tomb (坟墓)-Sweeping Day, also known as Qingming Festival. This year, the day 1 on April 4th.

    Tomb-Sweeping Day is a(n)2 Chinese festival. It began over 2,000 years ago. A well-known poem by the Tang Dynasty poet Du Mu 3 the day: “Rains fall heavily as Qingming comes, and passersby with lowered spirits go. A drizzling rain falls on the mourning Day, the mourner's heart is breaking on his way.”

    Tomb-Sweeping Day has been a public 4 on the Chinese mainland since 2008. On this day,5 bring flowers, food and wine to their ancestors' tombs (坟墓). They put food like cakes and fruits in front of the tombs. After that, they 6 the dirt (尘土) off the tombs and remember their dead family members.

    7 do Chinese people do this? That's because people think that visiting tombs during Qingming Festival is to 8 respect (尊重) to their dead family members.

    However, Tomb-Sweeping Day is not only about this. During that time, the weather is getting 9. So Tomb-Sweeping Day also means finally being able to garden and enjoy outdoor activities in China. Families often 10 for outings or fly kites at this time.

29.【历史上重大改革回眸】

材料:明代中叶,田赋制度发生了重大变化,其中最引人注目的,一是金花银的出现,而是苏(州)松(江)府等地的均田均粮活动。金花银即货币化的田赋,它是封建国家为保证朝廷财赋收入对实物田赋制进行的灵活改革。“以太祖尝折纳税粮于陕西、浙江,民以为便。遂仿其制,米麦一石,折银二钱五分。南畿、浙江、江西、湖广、福建、广东、广西米麦共四百余万石,折银白万余两,入内承运库,谓之金花银,其后概行于天下。”与金花银几乎同时发生的还有明中叶江南的均田、均粮活动。这里所说的均田、均粮不是平均地权,而是“欲因田以平其赋,使无不税之田”。
