Exercise这个单词在英语中可以用作动词或名词。作为动词时,它的第三人称单数形式为exercises,而作为名词时,它的复数形式是exercises。
那么,什么情况下会用到exercise的复数形式呢?通常,当我们需要指代多个不同种类的体育锻炼或健身活动时,就需要用到exercises的复数形式了。例如:
- She does a variety of exercises to stay in shape, including running, swimming, and weightlifting.(她做各种各样的锻炼来保持身材,包括跑步、游泳和举重。)
- Our gym offers a range of exercises for people of all fitness levels.(我们的健身房提供适合各种身体状况的锻炼。)
- The personal trainer designed a customized program with exercises that target specific muscle groups.(私人教练设计了一个定制的计划,包括针对特定肌肉群的锻炼。)
需要注意的是,当我们指代同一种体育锻炼或健身活动时,通常不需要使用exercises的复数形式。例如:
- He does yoga every morning to start his day.(他每天早上做瑜伽开始新的一天。)
- Running is a great way to improve cardiovascular health.(跑步是改善心血管健康的好方法。)
- She enjoys swimming laps in the pool for exercise.(她喜欢在泳池里游泳锻炼。)
总之,exercise作为名词时,其复数形式为exercises,通常用于指代多种体育锻炼或健身活动。
