2b Read the passage and answer the questions. (阅读短文并回答问题。)

Passage (原文):

Have you ever wondered what the most famous Chinese porcelain is? It is from Jingdezhen. Jingdezhen has been famous for its porcelain for over 1,000 years. The town is in Jiangxi Province, and it is known as the "Porcelain Capital" of the world.

The clay from the hills around Jingdezhen is very special. It is a white soft clay, and it is perfect for making porcelain. The process of making porcelain is complex. First, workers shape the clay into different kinds of objects, like bowls and vases. Then, they let the clay dry. After that, they put the clay pieces into a kiln at a very high temperature. The high heat makes the clay become hard and strong. Finally, workers paint the objects and fire them again to make the colors bright.

Today, Jingdezhen is not only a center for making traditional porcelain. It is also a modern center for creating new styles of porcelain art. In fact, Jingdezhen's porcelain is so popular that it can be found in homes and museums all over the world. Jingdezhen is a great example of traditional Chinese art that is still important today.

Translation (中文翻译):

你是否曾经好奇过中国最著名的瓷器是什么？它来自景德镇，景德镇以其瓷器闻名已有1000多年了，这个小镇位于江西省，被誉为世界“瓷都”。

景德镇周围山里的泥土非常特别，它是一种白色的软泥，非常适合制作瓷器，制作瓷器的工艺很复杂，工人们将泥土塑造成不同种类的物品，比如碗和花瓶，他们让泥土晾干，之后，他们把泥坯放入窑中，在非常高的温度下烧制，高温使泥土变得坚硬结实，工人们给物品上色，并再次烧制,使颜色更加鲜艳。

景德镇不仅是制作传统瓷器的中心，也是一个创造新型瓷器艺术的现代中心，景德镇的瓷器非常受欢迎，以至于在世界各地的家庭和博物馆里都能找到它,景德镇是一个至今仍然重要的中国传统艺术的绝佳典范。

第二部分：课文核心知识点解析

这篇短文是学习被动语态和“be made of/from/in”短语的绝佳材料。

核心短语：be made of/from/in

• be made of (由...制成)

  • 含义：指从成品中能看出原材料,物理结构没有改变。
  • 文中的应用：
    • The clay... is a white soft clay. (泥土是白色的软泥。)
    • workers shape the clay into different kinds of objects (工人们把泥土塑造成物品)
    • They paint the objects (他们给物品上色)
  • 虽然原文没有直接用 be made of，但整个过程描述了 of 的关系：物品是由泥土构成的。

• be made from (由...制成)

  • 含义：指从成品中看不出原材料,经过了化学变化或复杂的加工过程。
  • 文中的应用：这是本课的重点！
    • The clay... is perfect for **making** porcelain. (泥土非常适合制作瓷器。)
    • The high heat **makes** the clay **become** hard and strong. (高温使泥土变成坚硬结实的东西。)
    • Jingdezhen's porcelain can be found... all over the world. (景德镇的瓷器可以在世界各地找到。)
  • 语法点：这里大量使用了被动语态，瓷器是被制作出来的，泥土是被烧制变硬的，瓷器是被找到的。

• be made in (在...制造)

  • 含义：指产品的产地或制造地。
  • 文中的应用：
    • It is **from** Jingdezhen. (它来自景德镇。)
    • The town is **in** Jiangxi Province. (这个小镇在江西省。)
    • It is known as the "Porcelain Capital" **of** the world. (它被誉为世界“瓷都”。)
  • 注意：be made in 的被动形式是 be made in + 地点，This cup is made in Jingdezhen. (这个杯子是在景德镇制造的。)

核心语法：被动语态

短文中几乎每一步制作过程都使用了被动语态，强调了“瓷器”本身，而不是“谁”制作的。

• 被动语态结构：be + 动词的过去分词
• 文中的被动语态句子分析：
  1. Jingdezhen **has been famous** for its porcelain for over 1,000 years.
     • 时态：现在完成时被动语态 (has been + p.p.)
     • 含义：景德镇以瓷器闻名这个状态从过去一直持续到现在。
  2. The clay **is shaped** into different kinds of objects...
     • 时态：一般现在时被动语态 (is + p.p.)
     • 含义：泥土被塑造成物品。（省略了 by workers）
  3. `Then, it is let dry.**
     • 时态：一般现在时被动语态 (is + p.p.)
     • 注意：let 的过去分词是 let。
  4. After that, the clay pieces **are put** into a kiln...
     • 时态：一般现在时被动语态 (are + p.p.)
     • 含义：泥坯被放入窑中。
  5. The high heat **makes** the clay **become** hard and strong.
     • 这是一个主动语态，但 make sb/sth do sth 的结构在这里描述了一个因果关系，如果用被动，可以说 The clay is made hard and strong by the high heat. (泥土被高温变得坚硬结实。)
  6. Finally, the objects **are painted** and **are fired** again...
     • 时态：一般现在时被动语态 (are + p.p.)
     • 含义：物品被上色，被再次烧制。（并列的被动结构）
  7. `...it can be found in homes and museums all over the world.**
     • 时态：含有情态动词的被动语态 (can be + p.p.)
     • 含义：它可以在世界各地的家庭和博物馆里被找到。
