restrictive relative clause 限制性定语从句
It gives essential information to identify or define the noun (antecedent先行词) it modifies. Without it, the meaning of the noun would be unclear.
Please read the following sentences from your textbook. Work with your partner to translate them into Chinese.
Task 1:Read and Translate (阅读并翻译)
The couple who live next to us volunteered to help.
The supplies which were provided to the disaster area were collected...
Mr Li is an architect whose designs for the new town have won praise.
A doctor with whom James used to work died...
Activity 1:Observe and Analyze (观察与分析)
Task 2:Identify Antecedents & Relative Pronouns (找出先行词和关系代词)
Circle the antecedent (先行词) in each sentence.
Underline the relative pronoun (关系代词) that introduces the clause.
Summary of Rules (规则总结)
先行词 (Antecedent) 关系代词 (Relative Pronoun) 功能 (Function) 示例 (Example) 备注 (Notes)
人 (Person) who / that 作从句的主语或宾语 The couple who live next to us... that 在此作主语可互换 who
物 (Thing) which / that 作从句的主语或宾语 The supplies which were provided... that 在此作主语可互换 which
人 / 物 (Person/Thing) whose 作从句的定语,表示“...的” Mr Li is an architect whose designs... 表示所属关系

Key Takeaway (重点):
Restrictive Relative Clauses provide essential information to identify the noun. (限定性定语从句提供必不可少的信息来限定先行词。)。Whose is used to show possession for both people and things, meaning "of whom" or "of which".
