知识扩展：

1. how long 多久（用来提问有多长时间）

回答通常是more than two weeks、for a week、ten years等表示一段时间的状语。

例：-How long did you study English in China? -For three weeks.

2. how soon 用来提问"需要多长时间才会"，指某一动作要多长时间以后才能完成或发生。

回答通常是"in＋一段时间"

例：-How soon will you come back？ -In a week.

【活学活用】用how far, how often, how long填空。

1) does she usually exercise? 2) is it from your home to the school?

3) have you been away from (离开) your hometown?

4.【区别】How often和How many times

① How often用来提问某个动作间隔多久发生一次，即询问动作发生的频率。通常对一些表示频

率的副词进行提问；也可以对频度短语进行提问。

② How many times意思是"多少次"，用来提问做某事的次数，往往就once, twice, three times等

词语进行提问。

典型例题：

1）Li Ming does his homework every day. （就划线部分提问）→How often does Li Ming do his homework?

解析：every day属于频度短语，就频度短语提问用How often.

2）The old man went to the zoo three times this year.（就划线部分提问）→

How many times did the old man go to the zoo this year?

解析：这里就次数提问用how many times.

课堂巩固：

一、用所给词的正确形式填空

1. I watch TV _________ (one) a week. 2. He watches TV _________ (two) a week.

3. Katrina __________ (exercise) every day.
