文法句型

strenuous + noun (exercise, work, hike, task)

be + strenuous

用法筆記

Commonly used before nouns that describe physical activities (exercise, work, hike) or mental tasks (study, research). Can also be used predicatively: 'The hike was strenuous.' The word does not describe how a person feels — it describes the activity itself.

常見錯誤

❌I felt strenuous after the run.
✅I felt exhausted after the strenuous run.
💡strenuous describes the activity, not how a person feels after doing it.
❌He is a strenuous person.
✅He enjoys strenuous activities.
💡strenuous is rarely used to describe a person's character; it describes actions, tasks, or efforts.

反義詞

文法句型

strenuous + noun (effort, opposition, objection, attempt)

用法筆記

Frequently appears in the patterns 'strenuous + noun' where the noun names a goal-directed action (effort, attempt, campaign) or a reaction to it (opposition, objection). The focus is on the vigour and determination behind the action, not the difficulty of the task.

常見錯誤

❌She made a strenuous climb up the stairs.' (when meaning a determined effort, not a physically hard climb).
✅She made a strenuous effort to climb the stairs despite her injury.
💡Use 'strenuous effort/attempt' for determination; use 'strenuous climb/exercise' for physically demanding activity.
