以下是对“because”用法的总结，并附上一些常见例句和结构，帮助大家更好地理解和使用这个连词。
一、基本用法总结
| 用法类型 | 说明 | 示例 |

| 与“why”搭配 | 用于疑问句中，询问原因 | Why did you leave? Because I was tired. |
| 与“so”搭配 | 表示因果关系，强调结果 | It was cold, so I wore a coat.（注意：这里不常用“because”） |

3. 口语中常用“’cause”：在非正式场合，人们常把“because”缩写为“’cause”。例如：
- I didn’t go ’cause I was busy.

1. 根据给出的原因，写出完整的句子。
- 原因：I was hungry
- 句子：I ate a sandwich because I was hungry.
2. 将两个简单句合并成一个复合句，使用“because”连接。
- 句子1：It rained.
- 句子2：We stayed inside.
- 合并后：We stayed inside because it rained.
3. 改写句子，将“because”替换为其他表达方式。
- 原句：He missed the train because he was late.
