一般过去时在英语语法体系中承担两个关键作用:
功能类型 | 典型例句 | 语法解析 |
---|---|---|
特定时间动作 | The delegation arrived at noon precisely | 明确时间状语last spring等 |
状语从句替代 | She promised to call when ready | 条件从句中的特殊用法 |
Her brother taught chemistry(侧重过往经历)
Her brother teaches chemistry(强调现职状态)
We completed the task this morning(下午陈述)
We've completed the task this morning(仍在上午)
在复合句中需特别注意时态呼应,例如:"She assured us the package would be delivered once the payment cleared" 中主从句时态的逻辑关联。
1. 建立时间轴笔记法记录典型例句
2. 每周进行时态转换专项训练
3. 通过英语日记强化时态应用
