1. Introduction

In Mandarin Chinese, the character 由 (yóu) is used to indicate the passive voice, which highlights who or what is responsible for an action. This is particularly useful when the focus is on the action or the person affected rather than the doer of the action.

Detailed Explanation

The structure of a passive sentence using 由 (yóu) typically follows this pattern:

• Subject + 由 (yóu) + Agent + Verb + (Object)

Structure

• Subject: the entity that undergoes the action

• Agent: the doer of the action
• Verb: the action being performed

• Passive Voice with 被 (bèi): While 由 (yóu) introduces the agent in the passive construction, 被 (bèi) omits the agent and can sometimes imply a stronger sense of passiveness or negative connotation.
  • Example with 被: 这本书被张老师教了 (This book was taught by Teacher Zhang).
  • Example with 由: 这本书由张老师教 (This book is taught by Teacher Zhang).

5. Cultural Notes

Cultural Relevance

In Chinese culture, it's common to emphasize the action or outcome rather than the agent, reflecting social norms of modesty and the collectivist mentality. Using 由 (yóu) maintains politeness by acknowledging the doer's role, which is appreciated in formal settings.

Idiomatic Expressions

• 由你决定 (Yóu nǐ juédìng): "It's up to you to decide."
  • This expression invites someone to take responsibility in decision-making.

6. Common Mistakes and Tips

Error Analysis
