介词短语:含例句的完整指南

介词短语:含例句的完整指南

介词短语是英语中最常见的结构之一,几乎出现在你阅读或说出的每一个句子中。尽管使用频率极高,许多学习者仍难以正确识别和使用介词短语。理解介词短语的工作原理将提升你的写作水平,使你的语法更加精准,帮助你更清晰地表达自己。

本指南涵盖你需要了解的一切:介词短语是什么、它在句子中如何发挥作用、最常见的例子,以及需要避免的错误。无论你是在复习基础英语语法,还是在提高高级技能,掌握介词短语都至关重要。

什么是介词短语

介词短语是以介词开头、以名词、代词或名词短语(称为介词宾语)结尾的一组词。这个短语作为一个整体,修饰句子中的其他词或提供附加信息。

基本结构:

介词 + (可选修饰语)+ 介词宾语

例如: - "on the table"(介词:"on",宾语:"table") - "in the morning"(介词:"in",宾语:"morning") - "with my best friend"(介词:"with",宾语:"friend",修饰语:"my best") - "between the two buildings"(介词:"between",宾语:"buildings",修饰语:"the two")

介词短语有两种主要语法功能:

1. 形容词短语 — 修饰名词或代词,回答"哪一个?"或"什么类型?"的问题 - The book on the shelf is mine.(哪本书?架子上那本。) - The woman in the red dress is my teacher.(哪个女人?穿红裙子的那个。)

2. 副词短语 — 修饰动词、形容词或另一个副词,回答"在哪里?""什么时候?""怎么样?"或"为什么?"的问题 - She studied at the library.(她在哪里学习?) - We arrived before noon.(我们什么时候到达?) - He spoke with confidence.(他是怎么说的?)

理解这种区别有助于你准确分析句子并构建更清晰的句子。要了解这些结构如何融入整体画面,请参阅我们的英语语法规则完整指南。

英语中有数百个起固定表达作用的介词短语。将这些短语作为固定整体来学习,而不是每次都试图确定正确的介词,是提高流利度最有效的方法之一。

以下是按介词分类的最常用介词短语:

与"in"搭配: "in time," "in fact," "in charge of," "in common," "in detail," "in favor of," "in general," "in addition to," "in case," "in touch"

与"on"搭配: "on time," "on purpose," "on behalf of," "on the other hand," "on average," "on the whole," "on the way," "on foot"

与"at"搭配: "at first," "at last," "at least," "at once," "at risk," "at the moment," "at the same time"

与"by"搭配: "by accident," "by all means," "by heart," "by mistake," "by the way," "by yourself"

与"for"搭配: "for example," "for good," "for instance," "for the time being," "for sure"

与"out of"搭配: "out of breath," "out of date," "out of order," "out of the question," "out of practice"

与"under"/"with"搭配: "under control," "under pressure," "under the circumstances," "with regard to," "with the exception of," "without a doubt"

用这些固定介词短语来扩充你的英语词汇量,将帮助你在写作和对话中听起来更自然、更流利。

句子中的介词短语

单独理解介词短语很有用,但了解它们在完整句子中如何发挥作用,才能真正发展流利度。让我们来看看介词短语如何融入更复杂的写作和表达中。

单个介词短语: - The cat sat on the mat.

这里,"on the mat" 是一个副词短语,告诉我们猫坐在哪里。

一句话中有多个介词短语: - The students in the classroom studied for three hours without a break.

这句话包含3个介词短语:"in the classroom"(修饰students的形容词短语)、"for three hours"(修饰studied的副词短语)和"without a break"(修饰studied的副词短语)。

叠加介词短语: - The painting on the wall in the hallway of the museum is famous.

有时介词短语会串联在一起。每个短语修饰前一个短语的宾语:画在墙上,墙在走廊里,走廊属于博物馆。

句首的介词短语: - After the lecture, the students discussed the topic. - In addition to grammar, pronunciation requires daily practice. - During the summer, many international students enroll in intensive English programs.

用介词短语开头是在写作中增添变化、在主句前提供背景信息的常用方式。

修饰形容词的介词短语: - She is good at math. - He was tired of studying alone. - They were ready for the exam.

在这些情况下,介词短语补充形容词的含义。英语中许多形容词与介词的搭配是固定的,需要记忆。

正式与非正式语境中的介词短语:

正式:The report was submitted on behalf of the committee. 非正式:I did it on my own.

正式:The decision was made with respect to the new policy. 非正式:She made extra effort to help me.

在Columbia West College (CWC)这样注重口语的项目中,学生在正式和非正式两种语境下练习使用介词短语。CWC独特的English Speaking Success (ESS)项目通过多个层面实现这一目标:

  • 每天80分钟的口语课,配合"Connection Questions"等练习 — 学生在自发的对话场景中练习目标语法结构,而非填空练习
  • 综合课程 — 上午9点在语法课学到的介词短语规则,在上午10:30的口语课中立即得到练习,并在阅读与写作课中再次得到强化。一天内三次接触,每次在不同的语境中
  • 每周演讲,学生有意识地融入正在学习的语法结构,同时培养专业沟通技能和日常口语流利度

想在语境中练习语法吗? CWC的强化英语项目将结构化语法教学与每日口语练习相结合,让介词短语用法等规则变得自然而然。探索CWC的项目。

介词短语的常见错误

即使是英语高级学习者也会在介词短语上犯错。以下是最常见的错误及如何避免。

错误1:使用错误的介词。

这是最常见的错误。许多介词短语是固定表达,介词不能随意替换。

  • 错误:She is good in math.
  • 正确:She is good at math.

  • 错误:I arrived to the airport.

  • 正确:I arrived at the airport.

  • 错误:He depends from his parents.

  • 正确:He depends on his parents.

困难在于介词的选择往往不遵循逻辑规则,这只是英语发展的方式。最好的方法是将完整的介词短语作为一个整体来学习,而不是仅凭意思来判断正确的介词。

错误2:添加不必要的介词。

英语中某些动词不需要介词,但学习者因为母语需要而添加了介词。

  • 错误:She entered into the room.(在此语境中,"enter"不需要"into"。)
  • 正确:She entered the room.

  • 错误:We discussed about the problem.

  • 正确:We discussed the problem.

  • 错误:He reached to the top.

  • 正确:He reached the top.

错误3:省略必要的介词。

反过来的问题也会出现——省略英语所需的介词。

  • 错误:I listened the teacher.
  • 正确:I listened to the teacher.

  • 错误:She agreed my suggestion.

  • 正确:She agreed with my suggestion.

错误4:混淆时间和地点中的"in"、"on"和"at"。

这3个介词遵循一般规律:

时间: - At 用于具体时间:at 3 p.m., at noon, at night - On 用于具体日期:on Monday, on July 4th, on my birthday - In 用于较长时期:in January, in 2026, in the morning

地点: - At 用于具体地点:at the bus stop, at the door, at 123 Main Street - On 用于表面:on the table, on the wall, on the second floor - In 用于封闭空间:in the room, in the car, in Los Angeles

错误5:介词短语悬空或位置错误。

介词短语应放在它所修饰的词附近,以避免混淆。

  • 不清楚:She served cake to the children on paper plates. (是孩子们在纸盘上,还是蛋糕在纸盘上?)
  • 清楚:She served cake on paper plates to the children.

  • 不清楚:The man walked the dog with a red hat. (是男人还是狗戴着红帽子?)

  • 清楚:The man with a red hat walked the dog.

在CWC,经验丰富的教师会在口语课进行中立即发现介词短语错误。纠正过程不仅仅是指出错误:

  1. 示范正确形式,让学生重复
  2. 建议更自然的介词选择的替代表达
  3. 以支持性方式纠正 — 目标是建立信心,而非制造焦虑

CWC所有教师至少持有学士学位和最少3年ESL教学经验,CWC还投资于每月的专业发展研讨会。即时反馈与积极学习环境的结合能防止错误成为根深蒂固的习惯。

错误6:以介词结束句子(何时需要注意)。

你可能听说过"不要以介词结束句子"的旧规则。在现代英语中,这条规则在口语和随意语境中已基本过时。"Who are you waiting for?" 是完全自然的表达。然而,在非常正式的写作中,对句子进行重组("For whom are you waiting?")可能更受欢迎。

常见问题

最常见的介词短语有哪些?

英语中最常见的介词短语包括 "in fact," "on time," "at least," "in front of," "because of," "in addition to," "on behalf of," "at the same time," "by the way," 和 "out of"。这些短语在口语和书面语的各种语境中频繁出现。以"in"、"on"和"at"开头的短语尤为常见。将这些高频介词短语作为固定整体来学习,比每次从规则构建更有效率。有关完整参考,请参阅我们的100+例句介词短语列表。

如何在句子中识别介词短语?

要识别介词短语,请找介词(如in, on, at, by, for, with, about, between, through, during)后面跟着名词或代词的结构。短语包括介词、介词与宾语之间的修饰语,以及宾语本身。例如,在"The book on the old wooden shelf is mine"中,介词短语是"on the old wooden shelf"——介词"on"、修饰语"the old wooden"和宾语"shelf"。一个有用的测试是问:删除该短语后,句子是否仍然语法完整?如果是,你很可能找到了一个介词短语。

一个句子可以有多个介词短语吗?

可以,句子中经常包含多个介词短语,语法上没有数量限制。例如:"The student from Brazil in my class studied at the library with her friends for three hours during the afternoon." 这一句话包含6个介词短语,每个都添加了关于谁、在哪里、和谁、多长时间以及何时的具体信息。在学术和专业写作中,含3或4个介词短语的句子极为常见。关键是将每个短语放在它所修饰的词附近,使句子保持清晰易懂。
