逗号

3. 引导词的不同

1) He’s a man people like at first sight. (省略了_____________)
2) I have lost the bananas I bought this morning. (省略了______________)
3) I passed him a glass of beer, which he drank immediately. (__________不可省略)
总结:在限制性定语从句中,关系词有时可以省略,而在非限制性定语从句中关系词一律*不能省略。如在限制性定语从句中,that在从句中做____________时(成分),通常可以省略;而在非限制性定语从句中,关系代词不可省略。例如:
that/who

名称 意义 结构要求 功能 引导词 翻译法
限制性定语从句 起限定作用, 指特定的人或物, 不可省略,否则原句的句意不完整 紧跟先行词, 同先行词之间一般不加逗号 修饰先行词 关系代词、关系副词that作宾语时可省略 一般译为“...的”
非限制性定语从句 仅作补充或说明,若省略掉,原句的句意也完整 用逗号与主句隔开 修饰先行词或整个主句 一般不用that、why 可译为并列分句
