发现一
发现语法规律
频率副词always(总是), usually(通常), often(经常), sometimes(有时候), 还有hardly ever(几乎不), never(从不),谈论习惯性、经常性的动作或状态，常常与一般现在时连用。
例如：他总是上课迟到。He always arrives late for class.
她通常晚上做家庭作业。She usually does her homework at night.
他们几乎不看电视。 They hardly ever watch TV.
What do you usually do on weekends I always exercise.
What do they do on weekends They often help with housework.
What does she do on weekends She sometimes goes shopping.
发现二
在一般现在时的特殊疑问句中，当主语为第一人称、第二人称或第三人称复数时，在疑问词后，主语之前加助动词do, 当主语为第三人称单数时，在疑问词后加助动词does, 其句型结构为：
①特殊疑问词+do+主语(第一人称，第二人称，第三人称复数)+动词原形+其他？②特殊疑问词+does+主语(第三人称单数)+动词原形+其他？
例如：How do they get to school What time does she get to school
特殊疑问句的答语句型结构为：
①主语(第一人称，第二人称，第三人称复数)+动词原形+其他。
②主语(第三人称单数)+动词原形加(s\es…)(三单形式)+其他。在一般现在时的一般疑问句中，助动词do\does要放在句首。如：他们通常在周未锻炼吗？
___ they often _______ on weekends
她一周上网二次吗？____ she ____ the Internet twice a week
Do exercise
Does use
What do you usually do on weekends I always exercise.
What do they do on weekends They often help with housework.
What does she do on weekends She sometimes goes shopping.
How often do you go to the movies I go to the movies maybe once a month.
How often does he watch TV He hardly ever watches TV.
发现三
how often 意为 “__________”，是用于提问表示 ____ 的特殊疑问词组。其答语应为表示 _____ 的副词或副词词组。句子的时态一般是_____________，也可以是一般过去时。答语（1）频度副词 alway， usually，often，sometimes，hardly ever，never
(2)every+名词单数everymorning/afternoon/evening/day /Sunday/weekend/week/month/term/year/…
(3)次数+一段时间 once a week/month/year twice a week /month/year three times a week/month/year four times a week/month/year

：频度副词以及对频率提问
概念：在一般现在时态的句子中，常出现usually，often，
sometimes，never等表示频率的状语。这些词在英语
中被称为频度副词。
频度副词强弱顺序。always(100％)>usually(80％)>often (60％) >sometimes(40％)>seldom(20％)>hardly(10％)
>hardly ever(5％)>never(0％)。seldom、hardly、hardly ever、never具有否定意义。
一般用how often…对频度副词进行询问。
频度副词的位置：
通常放在行为动词之前 ，其他动词（ be动词、助动词、情态动词）之后，运用时需注意句中时态的一致。 sometimes 有时可位于句首或句末。
The weather is usually hot in summer.
My parents are never late for work.
I often go to the movies with my friends .
We usually play football after school.
She always gets up at 6:30.
He sometimes watches TV.= Sometimes he watches TV.
He hardly ever goes out these days.
主语是三人称单数的时候，频度副词也不需要发生变化。
回答：never (从不） ……
every day / night
once a week / month
twice a week / month
three times a week / month
once or twice a week / month
每天/每夜
一周/一个月一次
一周/一个月两次
一周/一个月三次
一周/一个月一次或两次
how often “多久一次”， 常用来询问某一动作
或事情发生的频率。
对频度副词和表示事件发生频率的短语提问时，都要用how often。
注意一：how often、how long、how soon、how many times
how often 意为“多久一次”，用来提问频率。
how long 意为“（延续）多长时间”，用来询问时间的长短；也可询问某物的长度。回答时用for 或since引导的时间状语。
how soon 意为“还要多久（时间）才……”，一般用将来时态，回答用in 引导的时间状语。
how many times 意为“多少次”，用于询问次数，回答用once, three times等。
中考对接： (山东潍坊中考）—______do you go to Weifang Theatre —Once a month.
A . How soon B . How often
C . How much D . How long
巧记 sometimes, some times, sometime与some time
“有时”相聚加s（sometimes）,
“几次”分开带s（some times）。
相聚为“某时（sometime）”，
分开“一段时间（some time）”。
__________ I get up very late. 有时候我起床很晚。
I have read the story __________. 我已经看过这个故事很多次了。
I’ll go to Shanghai __________ next week. 下周我要去上海一段时间。
I will stay here for __________. 我某个时候会在这里待。
Sometimes
some times
sometime
some time
注意二：sometimes, some times, sometime与some time
注意三：hardly与hard
hardly用作副词，意为“几乎不，几乎没有”，表示否定意义，其同义短语为 almost not。 含有 hardly 的句子是否定句。可修饰动词或与ever连用构成词组。
例：I can hardly see. 我几乎什么都看不见。
hard 作副词，意为“努力地，猛烈地”修饰动词；它作形容词，意为“困难的，硬的”，修饰名词。
例：It is raining hard. 雨下得很大。（作副词）
The stone is very hard. 石头很硬。（作形容词）
一次 once， 两次 twice，
三次或三次以上用基数词加上 times,
three times, five times, one hundred times.
表示“……几次”的表达方法是：
once a day / a week / a month / a year
twice a day / a week / a month / a year
three times a day / a week / …
“次数”的表达方法
这些表次数的词后与一段时间连用，表示动作多长时间发生几次，即动作的频率。

语动词意为“可能是”,只能用在句中。它们有时也可互换。
Maybe you are right. =You may be right.
Maybe he likes running. = He may like running.
Maybe I’m not very healthy =I may be not very healthy.
注：副词maybe可以单独做答语，而may be 不能。
