I can't wait to take it again and experience the comfort and speed (that) the train can offer. 13 Yes, and it is the latest high‑speed train that runs between Shanghai and Beijing. Look and read. Presentation 02 Look at the pictures and read the sentences. Pay attention to the words in bold. Is it the fastest and most comfortable train that you have ever taken? 这就是那列你曾经乘坐过的速度最快、舒适度最高的火车吗？ I can't wait to take it again and experience the comfort and speed (that) the train can offer. 是的。我迫不及待想再坐一次，去感受这列火车所能带来的舒适与速度。 是的，它是往返于北京和上海之间最新型的高铁。 What sentences are these? Attributive clause (I) 定语从句 Presentation 02 Read and learn. 定语从句 Attributive clause (I) ✅基本概念 在复合句中，用来修饰名词 / 代词的从句叫定语从句。被修饰的名词叫先行词，紧跟先行词后面； that / which叫作关系代词，既连接主句和从句，又在从句内部充当句子成分（主语 / 宾语），翻译为 “…… 的”。 ✅核心关系代词用法 that：可指代人、动物、事物 which：只指代事物、动物 ⚠️注意：关系代词在从句中作主语，不能省略；作宾语，可以省略。 Presentation 02 Read and learn. 定语从句 Attributive clause (I) ✅三种句式拆解 ①关系代词作主语（不可省略 that/which） 结构：先行词 + that/which + 从句谓语 + 其他 例：It is the latest high‑speed train that runs between Shanghai and Beijing. 它就是那列往返于上海和北京之间运行的最新高铁。 👉that 指代 train，在从句作主语，后面直接跟动词 runs，that 不能删掉。 ②关系代词作宾语（可以省略 that/which） 结构：先行词 + (that/which) + 从句主语 + 谓语 Presentation 02 Read and learn. 例：experience the comfort and speed (that) the train can offer. 感受这列火车所能提供的舒适与速度。 👉that 指代 comfort and speed，作 offer 的宾语，括号表示 that 可以省略不写。 ③先行词被最高级修饰时，只能用 that，不能用 which 例：Is it the fastest and most comfortable train that you have ever taken? 这是你坐过的速度最快、最舒适的那列火车吗？ 👉先行词 train 前面有最高级 fastest /most comfortable，关系代词只能用 that。 Presentation 02 Read and learn. ✅使用标志词 见到先行词是人 / 物，后面用来修饰限定这个名词，就要考虑定语从句。 先行词前出现最高级（fastest, most…），关系代词优先选用 that。 ✅2 步判断技巧 1. 找先行词：看从句修饰的是哪个名词（人 / 物） 2. 看关系代词在从句里面做什么成分：   - 后面直接接动词 → 作主语，that/which不能省   - 后面接从句主语（人名 / 名词） → 作宾语，that/which可以省略 例： 主语：This is the book which tells old stories. 宾语：This is the book which I like. （which 不可省） （which 可省略） 作主语 作宾语 Presentation 02 Complete the table.
