swear在英语中有“咒骂”和“发誓”两种主要含义,可以作及物动词和不及物动词使用,常见搭配包括swear at(咒骂某人)、swear to do(发誓做某事)、swear an oath(宣誓)以及swear by(极其信赖)。掌握这些搭配并通过例句练习,能有效提升口语和写作中对该词的准确运用。

首先,理解swear的基本用法。当swear表示“咒骂”时,通常是不及物动词,后面需要接介词at,例如:He swore at the driver who cut him off.(他对着突然变道的司机骂了一句。)当表示“发誓”时,swear可以接that从句或不定式,例如:She swore that she would never lie again.(她发誓再也不说谎了。)I swear to tell the truth.(我发誓说实话。)此外,swear an oath是固定短语,意为“宣誓”,常用于法律或正式场合,例如:The president swore an oath to uphold the constitution.(总统宣誓维护宪法。)而swear by则有两种常用含义:一是“极其信赖”,如I swear by this brand of sunscreen.(我非常信赖这个防晒霜品牌);二是“以……的名义发誓”,如I swear by all the gods.(我以众神的名义发誓。)
为了帮助记忆,可以将swear的常见句型整理如下:1. swear + at + 某人/某物(咒骂)2. swear + to do/that从句(发誓)3. swear + an oath + to do(宣誓)4. swear + by + 某物(信赖)。在实际造句时,注意区分语境,避免混淆。例如,在描述愤怒情绪时用swear at,在表达决心时用swear to。
下面提供10个实用例句,覆盖不同用法:
- He swore loudly when he hit his thumb with a hammer. (他锤子砸到拇指时大声咒骂。)

- I swear I saw a UFO last night. (我发誓昨晚看到了UFO。)
- They swore to protect the kingdom at all costs. (他们发誓不惜一切代价保护王国。)
- The witness swore an oath to tell the whole truth. (证人宣誓说出全部真相。)

- She swore under her breath as she missed the bus. (错过公交车时,她低声咒骂了一句。)
- The two leaders swore an oath of friendship. (两位领导人宣誓建立友谊。)
在实际写作或口语中,可以通过替换主语、宾语和情态动词来灵活造句。例如,将“I swear”改为“He swore”或“They will swear”,将“to tell the truth”改为“to keep the secret”等。注意swear的过去式是swore,过去分词是sworn,不规则变化需牢记。

【常见问题】
问题1:用swear造句子时,如何区分“咒骂”和“发誓”的用法?
回答1:用swear造句子时,区分方法主要看上下文和搭配。如果后面接at(swear at someone),通常表示“咒骂”;如果接to do、that从句或an oath,则表示“发誓”。例如“He swore at the waiter”是咒骂,而“He swore to return”是发誓。
问题2:用swear造句子时,为什么不能直接说“He swore him”?
回答2:在英语中,swear表示“咒骂”时是不及物动词,不能直接加宾语,必须用介词at,即swear at him。如果表示“对某人发誓”,则用swear to sb,例如“He swore to his mother that he would be careful。”所以用swear造句子时,注意搭配介词。
问题3:用swear造句子时,常见的错误搭配有哪些?
回答3:常见错误包括:将swear at误用为swear to(如“He swore to the driver”应改为“He swore at the driver”);将swear by误用为swear in(swear in是“使宣誓就职”的意思,如“The president was sworn in”);以及忘记不规则变化(过去式swore,过去分词sworn)。用swear造句子时,建议先确认动词形式再写。
问题4:用swear造句子时,如何让句子更地道?
回答4:为了让用swear造的句子更地道,可以结合具体场景,例如愤怒时用“swear under one's breath”(低声咒骂),正式场合用“swear an oath”(宣誓),日常表达信赖用“swear by”。同时,使用副词如“loudly, angrily, firmly”来修饰,例如“He swore angrily at the broken computer。”这样句子更生动。
