Section A
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。
【区别】hardly与hard
① hardly不是hard加后辍所构成的，它是副词，常与can或any连用。
② 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
Section B
知识要点
1. 【区别】maybe, may be
maybe是副词，意思是“也许，可能”，相当于perhaps, 常用于句首。如：
Maybe he will call you tomorrow. 或许他明天给你打电话。
may be是由情态动词may和系动词be构成，译成汉语为“可能是”，在句中作谓语。如：Tom may be at home. 汤姆可能在家。
Maybe和may be有时可以互相转换。如：Maybe he is right.可等同于：He may be right. 2. although的用法
although表示“虽然”，是从属连词，引导让步状语从句，语气较重，且比较正式，所引导的从句放在主句前后均可，可用though替换。注意：though/ although不能和but同时出现在一个句子中，但可以和yet连用。如：
Although/Though it is snowing, it is not very cold.=It is snowing, but it is not very cold.= Although/ Though it is snowing, yet it is not very cold. 虽然下着雪，但并不是很冷。 随堂达标 一、单项选择
