2024届上海市高考英语语法专题二：时间状语从句 讲义

考点二：时间状语从句 1. 什么是时间状语从句？ 时间状语从句是复合句中的一个从句，用来描述主句中的动作发生的时间。时间状语从句通常由从属连词引导，它们与主句之间存在一定的关系。 2. 时间从属连词的分类 Simple Time Clauses（简单时间状语从句）： 描述具体的时间点。 when（当）： 用于特定的时间点。 Example: I will meet you at the park when the sun sets. while（当...的时候）： 表示两个动作在同一时间段内发生。 Example: She likes to read while she waits for the bus. as soon as（一...就...）： 表示主句动作紧跟在从句动作之后发生。 Example: I will call you as soon as I arrive home. Continuous Time Clauses（持续时间状语从句）： 描述主句中动作的持续时间。 while（当...的时候）： 描述两个动作在时间上的同时性。 Example: She watched TV while I was cooking dinner. as（当...时候）： 描述主句中动作发生的整段时间。 Example: I felt tired as I was working all night. 3. 易混淆的时间从属连词 when vs. while： "when" 强调两个事件在时间上的先后顺序。 "while" 强调两个事件在时间上的同时性。 as soon as vs. as： "as soon as" 表示主句紧跟在从句之后。 "as" 强调主句和从句的动作几乎同时发生。 例句： When I arrived at the party, everyone was already dancing. She loves to listen to music while she exercises. I will call you as soon as I finish my work. He started feeling better as the medicine began to take effect. 4.时间状语从句语法填空题 阅读下面的短文，根据文意和所给首字母，填入适当的词使短文完整。 The global economy has undergone remarkable changes over the past few decades.
