【英语四级because的用法辨析】在英语四级考试中,"because" 是一个高频词汇,常用于表达原因。虽然其基本含义是“因为”,但在实际使用中,它的结构和搭配往往容易被考生混淆或误用。本文将对 "because" 的常见用法进行总结,并通过表格形式清晰展示其区别与注意事项。
一、基本用法
1. because + 句子
表示“因为……”,后面接完整的句子,引导原因状语从句。
- 例句:I stayed up late because I had a lot of work to do.
我熬夜了,因为我有很多工作要做。
2. because of + 名词/代词/动名词
表示“由于……”,后面接名词性成分,不能接完整的句子。
- 例句:He was late because of the traffic.
他迟到了,因为交通堵塞。
二、常见错误对比
| 错误用法 | 正确用法 | 解释 |
| I was tired because the weather. | I was tired because of the weather. | “because”后需接完整句子,而“because of”后接名词或短语。 |
| She failed the exam because she didn’t study. | She failed the exam because she didn’t study. | 正确,因为“because”后接句子。 |
| He missed the bus because of rain. | He missed the bus because of the rain. | “because of”后应接名词“the rain”。 |
| I couldn’t go because I was busy. | I couldn’t go because I was busy. | 正确,符合“because + 句子”的结构。 |
三、特殊用法与注意点
- 注意语气和正式程度
在正式写作中,“because of”比“because”更常见,尤其是在书面语中。例如:
- 正式:The meeting was canceled because of bad weather.
- 非正式:The meeting was canceled because it was raining.
- 不要与“since”或“as”混淆
虽然“since”和“as”也可以表示“因为”,但它们通常用于较正式或书面语中,且位置不同(多放在句首)。
- 例句:Since I was tired, I went to bed early.
As it was raining, we stayed indoors.
四、总结表格

| because of + 名词/短语 | because of + 名词/动名词 | She was absent because of illness. | 后接名词性成分 |
| 不同于 since / as | 语法结构不同 | Since he is busy, he can't help. | 用于正式语境,常置于句首 |
