Your productivity is improved. Exercising makes you
more awake and ready to handle whatever is ahead of you for the day. You can
keep your head clear for 4—10 hours after
exercise.
请问这里的 after exercise 用得对吗?我感觉应该用 after exercising,是这样吗?
这是 2018高考英语全国卷Ⅱ的阅读理解七选五中的一个句子。
用 after exercise 或 after exercising 都可以。
用 after exercise 时,exercise 是名词(不可数);用 after exercising 时,exercise 是动词,exercising 是动名词。又如:
Your pulse rate increases after exercise. 运动之后,脉搏会加快。
It is nice to take a shower after exercising. 运动后淋浴是很舒服的。
原句:Your productivity is improved. Exercising makes you more awake and ready to handle whatever is ahead of you for the day. You can keep your head clear for 4—10 hours after exercise.
大意:你的生产力得到了改善。锻炼使你更加清醒,而且让你准备好去处理这一天中等着你去解决的任何事情。你能在运动过后 4-10 小时内保持头脑清醒。
