知识要点

1. How often多久(一次)：How often do you exercise? 你多久锻炼一次身体?

How often does your mother go shopping? 你妈妈多久购一次物?

【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”，是用来提问做某事的次数的，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.

2. hardly几乎不，简直不

There are hardly any students in the classroom.几乎没有学生在教室里。

There is hardly a cloud in the sky. 天空中几乎没有云。
