这篇文档是针对高中英语教学的,具体模块是Module Music Grammar,主要探讨了时间状语从句和过去完成时态这两个语法知识点。以下是这些知识点的详细解释:
1. **时间状语从句**:
- 时间状语从句用于描述一个动作在另一个动作发生时的状态或者与之同步发生的情况。常见的引导词包括:when, while, as, before, after, until/till, since, ever since, whenever, as soon as, no sooner… than, hardly / scarcely… when等。
- **When**:除了表示"当...时候",在某些句型中,如"Somebody was doing something when…",它还有"这时"或"那时"的意思,用来表达突然发生的事件。
- **While**:通常强调在某段时间内的同时发生,常与延续性动词连用。例如:"While they were doing homework, someone broke into the house."
- **As**:可以表示两个动作同时进行,强调伴随关系,有时也可译为"随着"。例如:"As he grew older, he found it difficult to compose good music."
2. **过去完成时态**:
- 过去完成时态表示过去某一时间或某一动作之前已经完成的动作或存在的状态,通常与by, before, until, when, after等连用。
- 例如:"I had just made the mistake when the teacher came in." 在老师进来之前,我已经犯了错误。
学习目标包括:
1. 学生应能独立掌握时间状语从句和过去完成时态的基本用法。
2. 通过合作学习,将所学应用于句型写作中。
3. 通过练习巩固这两个语法点。
课堂活动包括:
- 分析不同时间状语从句的用法和例句。
- 完成相关练习题以检验理解和应用能力。
- 小组合作,翻译句子,并进行展示和点评。
给出的练习题答案示例:
1. "When he returned from the school, his mother was cooking."
2. "While he was reading, his wife was cooking."
