区别】how often和how many times
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。
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。
区别】hardly与hard
hardly不是hard加后辍所构成的，它是副词，常与can或any连用。
hard可用作形容词，意思为“艰难的，困难的，勤奋的”可等同于“difficult”。它也可用作副词，意思是“努力地，刻苦地，猛烈地”。
典型例题：1) 学好英语不难。（翻译成英语。
解析： 答案是it’s not hard to learn english. 这里hard为形容词，艰难的，困难的。
2) we must努力学习).
解析：在英语中努力学习或努力工作，我们常用work hard来表示，这里hard是副词，修饰前面的动词work.故答案为：work hard
