【because和becauseof的区别】在英语学习中,"because" 和 "because of" 是两个常见的表达方式,它们都用于解释原因,但在用法上存在明显差异。掌握它们的区别有助于更准确地表达自己的意思。
一、基本区别总结
| 项目 | because | because of |
| 词性 | 连词(conjunction) | 介词短语(prepositional phrase) |

| 是否可以单独使用 | 可以 | 不可单独使用,需搭配介词 |
| 例句 | I stayed home because it was raining. | I stayed home because of the rain. |
二、详细解析
1. because 的用法
