文法句型

assume + that-clause

assume + noun phrase

用法筆記

Frequently followed by a that-clause. The speaker uses 'assume' when presenting an inference as their own judgment, not a confirmed fact. In past tense, the that-clause often backshifts: 'I assumed he was tired' rather than 'I assumed he is tired.'

常見錯誤

I assumed he is coming to the meeting.
I assumed he was coming to the meeting.
💡After past-tense 'assumed,' the verb in the that-clause should normally be in a past form.
I assume you will come tomorrow' (when the plan is confirmed)
I expect you to come tomorrow.
💡'Assume' should not be used for confirmed plans; use 'expect' or 'know.'

  • feign

    more formal, usually about emotions or physical states ('feign illness'); less common for identities

  • adopt

    neutral tone; 'adopt an accent' is similar, but 'adopt' does not imply deception as strongly

反義詞
  • reveal

    to show one's true identity or feelings, the opposite of hiding behind a pretended one

文法句型

assume + noun phrase (identity / feeling / manner)

用法筆記

The object is typically a publicly observable thing — an identity, name, expression, accent, or manner — that someone deliberately adopts. This sense is more formal than 'pretend' and implies a concrete change in appearance or behaviour, not just a mental act.

常見錯誤

She assumed a sad expression.
💡'Assume a look' or 'assume an expression' is more natural than 'assume a face.'
He assumed to be a doctor.
He assumed the identity of a doctor.' or 'He pretended to be a doctor.
💡'Assume' takes a direct noun object, not a to-infinitive.
