“is appropriate to”用法详解与例句大全

在英语学习中，“is appropriate to”是一个常用于正式或书面语境的表达，用来说明某事对特定场合、对象或情境是“合适的”或“恰当的”。本文将系统讲解其结构、用法、常见误区及实用例句。

两者常被混淆，但有细微差别：

• Appropriate to：强调与某人身份、地位、场合等内在属性相匹配。
  例：The dress was appropriate to the occasion.（这条裙子与场合很相称。）

四、使用注意事项

• “is appropriate to”后接名词或代词时，“to”为介词；后接动词原形时，“to”为不定式符号，二者语法功能不同。
• 该短语多用于正式文体，日常口语中可用“suitable for”或“okay for”替代。
