在英语中,频率副词后面应该加上动词的原形,而不是-ing形式。例如,“我经常在周末读书”应该是"I often read books on the weekends",而不是"I often reading books on the weekends"。即使有些动词本身就是-ing形式,使用频率副词时也要改成动词的原形。
事实上,频率副词后面应该加上动词的原形,而不是-ing形式。例如:
- I often read books on the weekends.(我经常在周末读书。)
- She seldom eats fast food.(她很少吃快餐。)
- They always arrive at the airport early.(他们总是提前到达机场。)
虽然有些动词本身就是-ing形式,但是在使用频率副词时,也要改成动词的原形。例如:
- She enjoys swimming in the pool.(她喜欢在游泳池里游泳。)
- He hates running in the morning.(他讨厌在早上跑步。)
