二、常用搭配与固定表达
除了单独使用外，许多介词常与动词、形容词或名词搭配，形成固定短语。例如：
- look after（照顾）
- take care of（照看）
- agree with（同意）
- depend on（依赖）
- wait for（等待）
- think about（考虑）
- run into（遇到）
- get along with（与…相处）
这些固定搭配在日常交流中非常常见，建议结合实际语境进行记忆和练习。
三、注意事项
1. 介词后接动名词：很多动词后面需要接介词加动名词结构，如：
- I am interested in learning Chinese.
- She is good at playing the piano.
2. 介词不能单独作谓语：介词本身不独立构成句子，必须与其他词搭配使用。
3. 介词的位置：在疑问句或否定句中，介词通常放在句尾：
- Where did you go to?
- I didn’t go anywhere.
4. 介词选择易混淆：如“in”与“on”、“at”与“in”在时间上的区别，需结合具体语境判断。
四、小结
英语中介词虽然数量不多，但其用法多样且灵活。掌握常见的介词及其搭配是提高英语水平的关键之一。通过不断积累和实践，学习者可以更自然地运用介词来表达清晰的意思。
