如何正确使用英语介词

作者：Wordvice China165更新于 2026年10月12日

介词是描述单词之间关系的词。介词能够描述某物或某人的位置。

Example: The cup is on the table.

在上例中，介词“on”描述了杯子和桌子之间的关系。介词也能描述事件发生的时间和方式。

Example: I arrived before him.

Example: I arrived by bus.

在上例中，介词“before”描述的是“I”何时到达的时间与“him”有关，而介词“by”表示的是乘坐“bus”是到达的方式。介词的主要作用是指示地点、时间和方式。另外，介词也可用于指示所有权和目的。

Example: The purpose of this study was to develop a highly heat resistant composite with a carbon fiber base.

Example: A book is for reading.

简单介词

简单介词描述两个词（通常是名词）在位置或时间上的关系。常用的简单介词包括：at, for, in, by, off, on, over, under。

Example: The sample was placed under a microscope.

Example: We have added additional information in the revision.

Example: The board meeting starts at 9:00 am.

Example: The sample was placed under a UV light for 30 minutes.

双介词

双介词通常表示方向，由两个简单介词组成。常见的双介词包括：into, onto, upon, up to, inside, outside of, out of, from within。

Example: We ran into the apartment.

Example: Progressively higher weights were placed upon the composite.

Example: The man walked up to the officer.

Example: Strange groans came from within the box.

复合（复杂）介词

复合介词表示位置，至少由两个词组成。常见的复合介词包括：in addition to, in front of, at the back of, along with, alongside of, in comparison to, in contrast to。

Example: In addition to the tests to evaluate heat resistance, we also submerged the samples in water to test their varying degrees of hydrophobia.

Example: I left the package in front of the door.

Example: He picked up a soda along with the pizza.

Example: Sample 1 demonstrated high heat resistance in comparison to sample 2.

分词介词

分词介词是作为介词使用的分词。它们以“-ed”或“-ing”结尾。常用的分词介词包括：considering, including, excluding, during, regarding, provided。

Example: Considering its high protein content, the sample’s resistance to heat was surprising.

Example: All of the samples, including the gold composite, were moved to a vacuum chamber.

Example: The professor talked about chirality during her lecture.

Example: The class will begin in five minutes, provided that all students are present.

短语介词（介词短语）

短语介词（又称介词短语）由介词、介词的宾语和修饰宾语的词组成。短语介词通常以这些词开头：for example, for instance, on time, under the influence of。

Example: They arrived at the restaurant on time.

Example: You should not drive under the influence of alcohol.

Example: For example, composite A did not degenerate when heat was applied.

Example: She appreciates the flowers from her children.

用介词结束句子

人们通常认为句子不能以介词结尾。这种假设其实不对。有时，在句末不使用介词会造成句子不够自然流畅。

不自然: Is this the movie about which you told me?

自然: Is this the movie you told me about?

另外，把介词移到句子中靠前的位置能够使句子显得更加正式。

非正式: What journal was your last paper published in?

正式: In which journal was your last paper published?

在上例中，这两个句子都正确，但后一句比前一句更加正式。因此，在学术写作中，介词很少用在句子末尾。

非正式: This is a topic we previously wrote about.

正式: This is a topic that we discussed in a previous paper.

当把介词移到句子中靠前的位置时，需要注意去掉在句子末尾的介词。

错误: In which journal was your last paper published in?

正确: What journal was your last paper published in?
In which journal was your last paper published?

避免不必要的介词

像形容词一样，介词也经常被滥用，即使母语是英语的作者也如此。为了确保介词使用正确，除了请经验丰富的英语母语编辑协助检查外，还可以用在线语法检查器找出并修正文章中的介词错误。滥用介词包括两种情况。第一种情况是在句子中错误使用介词。

错误: Where is the other student at?

正确: Where is the other student?

在上例中，介词“at”在语法上是多余和错误的。第二种情况是句子结构的写法不好，使用了太多介词。

Example: An understanding of gold composites is necessary for any company in the semiconductor industry at this time.

这种句子最好在结构上重写，使得无需使用那么多介词，示例如下。

Example: Understanding gold composites is necessary for companies in the semiconductor industry.
