【哪些介词后面要加ing形式】在英语语法中，介词的使用是一个非常重要的部分。许多学习者在使用介词时常常会遇到困惑，尤其是在介词后是否应该接动词的-ing形式（即动名词或现在分词）。其实，有一些常见的介词在固定搭配中后面必须接-ing形式，而有些则不能。以下是对这些介词的总结。
一、常见需要接ing形式的介词
在英语中，有一些介词在使用时通常后面接动名词（即动词+ing），这种结构常用于表达动作、状态或习惯等。以下是常见的这类介词：
| 介词 | 举例说明 |
| about | I'm thinking about going to the party. |
| after | She is interested in learning English. |
| before | He was tired of working all day. |
| by | The book is written by a famous author. |
| despite | She succeeded despite the difficulties. |
| during | We had a meeting during the lunch break. |
| for | He is responsible for organizing the event. |
| from | She is different from her sister. |
| in | He is good in math. |
| like | She looks like her mother. |
| of | He is proud of his success. |
| on | They are talking on the phone. |
| to | She is used to living in the city. |
| with | He is good with children. |
二、需要注意的情况
虽然上述介词通常接-ing形式，但在某些情况下，也可能接其他形式，尤其是当句子结构发生变化时。例如：
- after 后面有时也可以接动词原形，如：I will call you after I finish my work.
- before 后面也有可能接动词原形，如：He left before I arrived.
不过，在大多数情况下，尤其是当介词后面跟的是一个完整的动作或状态时，ing形式是更常见和自然的选择。
三、总结
总的来说，一些常见的介词在使用时后面通常接动名词（-ing形式），这在英语中是一种固定搭配。掌握这些介词的用法有助于提高语言表达的准确性和流畅性。建议在学习过程中多结合例句进行练习，并注意语境对语法结构的影响。
