常見錯誤
What are common mistakes with "Fitness"?Which "Fitness" sentences look correct but are wrong?
×I want to improve my fitness level.
✓I want to improve my fitness.
在英文中，'fitness' 本身已包含身體狀況或健康水平的概念，加上 'level' 是多餘的。直接使用 'improve my fitness' 即可。
×He has a good fitness.
✓He is very fit. / He has a good level of fitness.
'Fitness' 是不可數名詞，前面不能直接加 'a'。若要形容一個人體能好，應使用形容詞 'fit'，或使用 'a good level of fitness' 這樣的片語。
×I go to the fitness every day.
✓I go to the gym every day. / I work on my fitness every day.
'Fitness' 是一個抽象概念（體能、健康），不是一個具體的地點。想表達去健身的場所，應使用 'gym'（健身房）。若想強調進行健身活動，則說 'work on my fitness'。
×The fitness of the room is perfect for the meeting.
✓The room is perfectly suited for the meeting. / The suitability of the room is perfect for the meeting.
這裡混淆了 'fitness' 的兩個主要意思。在談論身體健康或體能時才用 'fitness'。表示某物是否『適合』某個目的，應使用 'suitability', 'appropriate', 或 'suited'。
×I bought a new fitness.
✓I bought some new fitness equipment. / I joined a new fitness program.
'Fitness' 是不可數的抽象名詞，不能直接與 'a' 連用或表示單個物品。必須具體說明是什麼，例如 'fitness tracker'（健身手環）、'fitness class'（健身課程）或 'fitness equipment'（健身器材）。
