需 注 意 几 个 细 节 知 识
1. exercise 的用法：
exercise作不及物动词，意思是“运动，锻炼”
My father exercises (动词单三)three times a day.我父亲每天锻炼三次。
作可数名词意为“练习，操”
I have a lot of exercises （可数名词复数）to do after school every day.
每天放学后我有许多练习要做。
do morning exercises做早操; do eye exercises做眼保健操.
作不可数名词，意思是“运动，锻炼”
You should take more exercise （不可数名词）if you want to be healthier.如果你想更健康，应该多运动。（每年常考more 和healthier两个比较级 much—more; healthy---healthier ）
2.here 的用法：(常考查主谓一致 和倒装问题，请掌握)
here位于句首时，主语如果为代词则用半倒装，即谓语在主语之后；主语如果为名词则用全倒装，即谓语在主语之前。
Here comes the bus.车来了。（动词comes在名词bus之前）
Here he comes.他来了。（动词comes在代词he之后）
here be 结构中，be的单复数取决于最靠近be这个名词的单复数。
Here are (be) your books.你的书在这儿。
Here is (be) your tea.你的茶在这儿。
3.maybe 与may be的区别：(常考查二者同义句的转化，请掌握)
① maybe是副词，意为“或许；大概”相当于perhaps，probably 放在句首作状语。
Maybe he can help you.
② may be 是情态动词may+动词原形be组成的，是动词短语常作谓语。
He may be at home. = Maybe he is at home.
3. although 与but (常考查二者同义句的转化，请掌握)
Although为从属连词，意思是“虽然，尽管”，引导让步状语从句；but为并列连词，与although不能同时使用，但although可与still和yet连用①Although; / ② /; although ③ /; but (正确)
Although he is old, he is still healthy.= He is old, but he is still healthy.尽管他很老，但是仍然健康

10.how与what的区分考查：
What…think of… How…like…
What…do with… How…deal with…
What…like about… How…like…
What’s the weather like today How’s the weather today
What to do How to do it
e.g. What do you think of this book =How do you like this book
I don’t know what I should do with the matter.=I don’t know how I should deal with it.
What do you like about China =How do you like China
I don’t know what to do next step =I don’t know how to do it next step

1. 表频率的词汇和短语：
always， usually ，often ，never， hardly， ever
sometimes， seldom， once a day， twice a month
three times a week ，every two weeks， once in a while
2. 模糊频率副词
以下些词都是表示事情发生频率的副词，也是不准确地说某事在一段时间内发生的次数。
always 总是 usually 通常 often 经常
sometimes 有时 hardly ever 几乎不 never 从来不
例如：
On weekends I always surf the Internet. I usually watch TV.
I often sleep late. I sometimes listen to music.
I hardly ever play computer games. I never play soccer.
我们按照频率发生的高低，可以将这几个词排列为always > usually > often > sometimes > hardly ever > never。
3．精确的频率副词
以下这些频率副词可以准确地表达事情发生的频率。
一次 once 两次 twice 三次 three times
四次 four times 五次 five times 六次 six times
注意：在记忆时，我们只要记住once（一次）和twice（二次）就可以了。其他发生次数只要用“数字＋times”来表达就可以了。例如：
I drink milk and eat vegetables every day.我每天喝牛奶，吃疏菜。
I exercise once a week.我每周锻炼一次。
I eat Mcdonald's twice a month.我一个月吃两次麦当劳。
I visit my grandmother four times a year.我一年去看奶奶四次。
4、其他的表达法：
every day 每天 once a week 一周一次 twice a month 一个月两次
four times a year 一年四次 once two weeks 两周一次 twice three months 三个月两次
4.频率副词常放在行为动词前，当句中有情态动词、助动词或be动词时，则放在这类动词后。
I often see her walk in the park.（行为动词）We must always remember this. (情态动词后)
5. 对频率副词提问的句型※How often... ※
“how often”的意思是“多久，多长时间”，用来专门询问事情发生的明确频率。回答的时候，就要用到刚才我们所学的once，twice，three times，four times等等这些词。 例如：How often do you brush your teeth I brush my teeth twice a day. What do you do on weekends
八年级上第一单元相关知识
1、问次数用how many times ；
I often go home three times a month. →How many times do you often go home a month
I often go home three times a month. → How often do you go home
2、hard 与hardly
①hard既可作形容词，修饰名词 hard work（艰苦的工作），又可作副词，常放在动词之后修饰动词work hard（努力地工作）
It rained hard / heavily yesterday afternoon.昨天下午天下大雨。
②hardly不是hard的副词，本身为否定意义的副词，意为“几乎不”。相当于almost not / seldom常考查其所在句子的反义疑问句。前否后肯。
Tom hardly went to the movies last week, did he
Tom went to the movies last week, didn’t he
3、health（副词） healthy（形容词） →healthily
Luck（副词） lucky （形容词）→luckily
noise（副词） noisy （形容词）→noisily
