something + happen

用法筆記

The subject is always an event, situation, or process — never a person performing the action. Frequently used in past tense forms (happened, had happened) in everyday conversation.

常見錯誤

❌I happened an accident yesterday.
✅An accident happened yesterday.
💡happen is intransitive; events happen, but people do not 'happen' things as an action.

同義詞
  • befall

    very formal, literary; used for serious or dramatic events

  • come over

    used only for people and feelings ('What came over him?')

文法句型

something + happen + to + someone/something

用法筆記

The affected person or thing is the object of the preposition 'to'. Common subjects include 'something terrible', 'nothing', 'what', 'the same thing', or a specific event.

常見錯誤

❌My arm happened a problem.
✅A problem happened to my arm.
💡the affected thing cannot be the subject of 'happen'; it must follow 'to'.

    less common, slightly more literary ('I chanced to meet him')

反義詞
  • plan to

    doing something deliberately rather than by chance

文法句型

someone + happen + to + infinitive

用法筆記

Always followed by a 'to'-infinitive. Not used in progressive or continuous forms (✓ I happen to know — ✗ I am happening to know).

常見錯誤

❌I am happening to know her from school.
✅I happen to know her from school.
💡happen in this sense never takes a continuous form.

同義詞
  • stumble upon

    similar in meaning but more informal; suggests a slightly accidental discovery

  • come across

    very common; can be used in all registers

反義詞
  • look for

    searching deliberately, opposite of finding by chance

文法句型

someone + happen + upon/on/across + something/someone

用法筆記

Must be followed by a preposition (upon, on, or across) — the verb cannot be used transitively. 'Happen upon' and 'happen across' are the most common forms in current English.

常見錯誤

❌I happened my old friend at the mall.
✅I happened upon my old friend at the mall.
💡this sense always needs a preposition (upon, on, or across).
