六、易错点
How often 问频率，回答用 every day / once a week。
学会了就试一试
这一课，我会用了
学习目标：能用 how often 询问活动频率，并用 every day、twice a week 等回答。
自己说一说
设想一位虚构人物的活动安排，问 How often do you...?，再用 once a week、twice a week 或 every day 回答；不评价他人的健康状况。
答对至少三题，再完成“自己说一说”。
过几天再想一想
- 明天：不看页面，分别用 once a week 和 twice a week 造句。
- 三天后：换一种活动，用 How often...? 完成一次问答。
