how often are you staying there?---for a week的句子中哪个词错了

often 错了，应该是：long
How long are you staying there?---for a week
你在那待多久了？---一个星期
How long 多久 的意思
How often 是问频率的，例如：.—How often does my daughter take the medicine?
—Three times a day.
表示“在某段时间内某种动作的次数”的状语提问时，都要用how often。换句话说，如果要回答由how often提问的句子，我们通常要用频度副词或诸如every day, each week, once a week, twice a day, four times a month等来回答。例如：
4. —How often do you borrow books from the library?
—Twice a month.
5. —How often does your mother do the washing?
—She does it every day.
6. —How often can you go to the movie?
—Once a week.

how often 是指多久一次。显然和你的答案不一样。你的答案是在回答。how long.多长时间。即使没有for a week这个回答，你举了how often句子也说不通，时态不对。How often does she draw a picture?你多久画一次画？你时态应该是现在式，进行式是不合逻辑的。

how often 改成 how long

how often 换成 how long
