【英语从属连词知识点归纳】在英语语法中,从属连词(subordinating conjunctions)是连接主句和从句的重要工具。它们用来引导从句,并表明从句与主句之间的逻辑关系,如时间、原因、条件、让步、目的等。掌握这些连词的用法,有助于提高英语写作和阅读理解能力。
以下是对常见英语从属连词的总结,包括其含义、用法及例句,便于理解和记忆。
一、从属连词分类及功能
| 类型 | 常见连词 | 功能说明 | 例句 |
| 时间 | when, while, as, before, after, until, since, once, whenever | 表示时间关系,说明主句动作发生的时间 | I will call you when I arrive. |
| 原因 | because, since, as, for, owing to, due to | 表示原因或理由 | She stayed home because she was sick. |
| 条件 | if, unless, provided that, as long as, in case | 表示假设或条件 | If it rains, we will stay indoors. |
| 让步 | although, though, even though, despite, in spite of | 表示让步,即使有某种情况 | Although it was cold, we went out. |
| 目的 | so that, in order that, to | 表示目的或意图 | He studied hard so that he could pass the exam. |
| 结果 | so...that, such...that | 表示结果 | It was such a beautiful day that we decided to go for a walk. |
| 比较 | than, as...as | 表示比较 | She is as tall as her brother. |
| 方式 | as, like, just as | 表示方式或方式对比 | Do it as I told you. |
二、使用注意事项
1. 从属连词引导的是一个完整的句子:不能单独使用,必须与主句结合。
- 正确:I didn’t know that he was coming.
- 错误:I didn’t know he was coming.
2. 有些连词可以互换使用,但语义略有不同:
- since 和 because 都表示“因为”,但 since 更常用于书面语,语气更正式。
- although 和 though 可以互换,但 though 更口语化。
3. 注意连词的位置:
- 从属连词通常放在从句开头,有时也可置于句中,但需注意句子结构。
- 例如:Although it was raining, we went out.
或:We went out although it was raining.
4. 避免重复使用连词:
- 不要在一个句子中使用多个从属连词来引导同一从句,除非是为了强调或特殊表达。
三、常见错误与辨析
| 常见错误 | 正确表达 | 解释 |
| I don't know if he will come. | I don't know whether he will come. | “whether” 用于正式语境,而 “if” 更口语化。 |
| I will go unless it rains. | I will go unless it rains. | “unless” 是 “if not” 的缩写,无需再加 “not”。 |
| He works hard because he wants to succeed. | He works hard in order to succeed. | “because” 表示原因,“in order to” 表示目的。 |
