一时 can describe only the present moment, never a past event.
一时 is not restricted to now. 一度 highlights a period or occasion, as in 曾一度想放弃, without specifying how long the phase lasted. 一时 describes a passing state of excitement at that earlier moment.
Repair the form before interpreting it
- The form he / him他o'clock时one / a一happy高兴 needs repair here. Write he / him他a period of time一时happy高兴 instead; keep the word or frame in its demonstrated order.
- Form and meaning are separate checks. After the repair, explain the sentence in its situation rather than treating a familiar translation as a universal rule.
Rewrite the demonstrated repair exactly: 他时一高兴
The demonstrated form is 他一时高兴. 一时 describes a passing state of excitement at that earlier moment.
Keep the distinction
- a period of time一时 describes a passing state of excitement at that earlier moment. Check the relevant speaker, time or group in the surrounding context.
- a period of time一时 is not restricted to now. at one time一度 highlights a period or occasion, as in great- (grandfather…曾at one time一度want / think / miss想to renounce放弃, without specifying how long the phase lasted.

Which means “at one time / once (in the past)”?
一度 often points to a phase; 一时 to a brief state. 一时高兴 can describe excitement during a past event.
In 这首歌前几年一度很流行，现在没人听了, the popularity is described as a past phase.
前几年 and 现在 provide the time contrast. 一度 alone does not specify the length of a phase.
A person once made a hasty decision while briefly excited. Close the examples. Say a Mandarin response, then write it in Chinese. Explain briefly in English what the lesson’s pattern adds. Compare with the model, then change one detail and try again.
This is supported productive practice. Compare meaning and structure; your answer need not copy the model. A partner or teacher must hear the spoken response to comment on pronunciation.
