“Exercise”在英语中既可以作可数名词,又可以作不可数名词,具体用法取决于其含义。
“Exercise”:可数还是不可数?
不可数名词
当“exercise”表示体育活动或身体锻炼时,它是不可数名词。例如:
Exercise is good for your health.(锻炼对你的健康有好处。) I need to get more exercise.(我需要多锻炼。) The doctor recommended daily exercise.(医生建议每天锻炼。)
可数名词
当“exercise”表示一个特定的锻炼项目或动作时,它是可数名词。例如:
I did 10 exercises in my workout today.(我今天在锻炼中做了 10 个动作。) The exercise was too difficult for me.(这个动作对我来说太难了。) My physiotherapist gave me a list of exercises to do.(我的物理治疗师给了我一份要做的锻炼清单。)
特殊情况
在某些情况下,“exercise”既可以是可数名词,也可以是不可数名词。例如:
可数名词:I need to do some exercises for my back pain.(我需要做一些锻炼来缓解我的背痛。) 不可数名词:Exercise is essential for a healthy lifestyle.(锻炼对于健康生活方式至关重要。)
区分可数和不可数用法时,需要考虑语境和“exercise”在句子中的含义。一般来说,当“exercise”表示一个抽象概念或普遍活动时,它是不定量名词;而当它表示一个特定的动作或锻炼时,它是可以定量名词。
