要点讲解
- always 总是(100%),usually 通常(90%),often 经常(70%),sometimes 有时(50%),seldom 很少(20%),never 从不(0%)。
- 位置:be 动词/情态动词之后,实义动词之前:He is always kind to us. / He often goes fishing on Sundays.
- sometimes 也可放在句首、句末:Sometimes I watch TV. / I watch TV sometimes.
- 对频度副词提问用 How often:—How often do you exercise? —Twice a week.
- 频率短语:once a week 每周一次,twice a month 每月两次,three times a day 每天三次。

易错提醒
- 频度副词在否定句中要注意部分否定:He doesn't often go there. 他不常去那里(不是"从不")。
