(二) What did you find out (探究语法规律)
探究一：频度副词与一般现在时的用法
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.
1.频度副词的概念及构成
在一般现在时态的句子中，常出现usually，often，sometimes，never等表示频率的副词。这些频度副词表示某一动作或状态出现的频率，即在一定时间内某一动作或状态重复出现的次数这些词在英语中被称为频度副词。一般来说可按频率大小排列为：always（总是100%）>usually（通常≥ 80%）>often（常常；经常≥ 60%）>sometimes（有时≥ 20%）>hardly ever（几乎从不＜ 5%）>never（从不0%）等。
2.频度副词的位置
频度副词放在系动词be、助动词或情态动词之后，行为动词之前。
eg：He is always asking for money.他总是要钱。
We often have lunch at school.我们经常在学校吃午饭。
They hardly ever make dinner.
I can never forget the day!
有些频度副词可放在句首或句尾，用来表示强调。
eg：Sometimes I walk home，and sometimes I go home by bus.
我有时步行回家，有时乘公共汽车回家。
never 位于句首，句子要倒装。eg：Never have I learnt this word.我从未学过这个单词。
Never 　　　　 （我能见到） this girl again.
探究二：助动词do 和does与一般现在时的用法
一般现在时中什么时候用do或does呢
在一般现在时疑问句或否定句中，当主语为第三人称单数时，则助动词用does;
她每天上网吗？ ____ she ____ the Internet every day
在一般现在时疑问句或否定句中，当主语不是第三人称单数时，则助动词用do。
他们通常在周未锻炼吗？ ___ they often _______ on weekends
助动词do 和does与一般现在时的句型结构
探究三：助动词do 和does与一般现在时的用法
How often 问句与一般现在时的用法和答语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。
翻译：你多久去游泳一次？一个星期三次。 ________________________________________________
How often + 助动词 do (does ) + 主语 + do sth. 疑问词 how often 是问频率 (多久一次),（这里助动词 do (does) 是起帮助构成疑问的作用）多与一般现在时连用,有时也和一般过去时连用。回答一般是用表示频率的副词。
答语有四种情况：
(1)频度副词 always， usually，often，sometimes，hardly ever，never
(2)every+名词单数every morning/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
(4)once every four years 每四年一次　seven times every two minutes每两分钟七次
Li Ming and his parents go to the park three or four times a month.
探究四：助动词do 和does与一般现在时的用法
how often与how long/far/soon的用法区别
【辨析】how often与how many times
how often 多久一次，用来询问在某一段时间内进行某个动作的次数。how many times 多少次，它不问动作发生的频率，只询问次数，即“多少次”。 其答语为once，twice，three times等。
eg：—How many times have you been to Beijing？ 你去过北京几次？
—Only twice.仅两次。
—How often do you go to Beijing？ 你多久去一次北京？
—Twice a month.每个月两次。
三、Post-grammar
1. plete the questions with do or does. Then match the questions and answers.
2.3b. Use the words given to write questions. Then ask and answer them with a partner.
3.Practice. What can you do to improve your English

5. Summary. Who is the best English student
6. Language points. Inquiry into knowledge by translation(翻译探究)
maybe & may be
maybe adv. ，意为“可能; 也许”。可以在句中的任何位置，通常位于句首，相当于perhaps。maybe是副词，在句子做状语。
may be modal v.，情态动词may 与动词原形be 一起构成句子的谓语动词，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。
---Does he like playing basketball ---Maybe. (Maybe not)
