2、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 th

3、e movie? -Once a week. 对划线部分提问：e.g. She usually comes to see her grandpa four times a month. （呼和浩特市中考题） _ _ _ she usually come to see her grandpa? 即时练解析：How often does。划线部分four times a month涉及频率，应用How often提问，同sometimes、usually、often、always、once、twice、once a week、twice a year等。句中动词comes为单三式，改为疑为句时应添

4、加助动词does，动词还原。（2012菏泽中考）- Steve, _ do you play basketball after school? - Twice a week. It can keep me healthy. A. how far B. how soon C. how long D. how often解析：选D。考查疑问词辨析。how far“多远”，问路程； how soon“多久；多久之后” ，对将来的一段时间之内或之后提问； how long “多长时间”，问时段；how often“多久一次”，问频率。由答语“Twice a week.”可知问频率, 故选D。1aLoo
