Unit 3 Keep Fit
核心语法:频度副词
一、什么是频度副词?
频度副词是表示动作或状态发生频率的副词,用来回答“How often... ”(多久一次?)的问题。
二、常见频度副词及频率程度
频率从高到低排列:
频度副词 含义 频率程度(估算)
always 总是 100%
usually 通常 约80%
often 经常 约60%
sometimes 有时 约40%
seldom/rarely 很少 约20%
hardly ever 几乎不 约5%
never 从不 0%
记忆口诀:
总是总是always,通常usually记心上;
经常often常出现,sometimes有时也不忘;
很少seldom要留意,几乎不hardly ever;
从不never是底线,频率高低心中藏。
三、频度副词在句中的位置
学习的重点和难点!频度副词有三个主要位置:
1. 在实义动词之前(最常用)
I always get up at 6:30.(我总是6:30起床。)
She often goes to the library.(她经常去图书馆。)
They usually have lunch at school.(他们通常在学校吃午饭。)
2. 在be动词之后
He is always late for school.(他总是上学迟到。)
We are sometimes busy on weekends.(我们周末有时很忙。)
She is never angry with me.(她从不生我的气。)
3. 在情态动词或助动词之后
I can always help you.(我总是能帮助你。)
You should often review your lessons.(你应该经常复习功课。)
They don't usually watch TV.(他们通常不看电视。)
位置规律总结:
实义动词前,be动词后,情态助动夹中间。
四、特殊用法与注意事项
1. sometimes 的特殊位置
sometimes可以放在句首、句中或句末,位置比较灵活:
Sometimes I walk to school.(有时我步行上学。)
I sometimes walk to school.
I walk to school sometimes.
2. 频度副词与否定句
当句中有频度副词时,否定词not要放在频度副词之后:
She does not always come on time.(她不总是准时到。)
She always does not come on time.
3. 对频度提问
用 How often... 提问:
How often do you exercise (你多久锻炼一次?)
I exercise three times a week.(我每周锻炼三次。)
4. 频度副词与一般现在时
频度副词常与一般现在时连用,表示经常性、习惯性的动作:
My father never smokes.(我父亲从不吸烟。)
They often play basketball after school.(他们经常放学后打篮球。)
五、与频度副词连用的时间短语
时间短语 含义 示例
every day/week 每天/每周 I read English every day.
once/twice a week 一周一/两次 He swims twice a week.
three times a month 一月三次 We visit our grandparents three times a month.
on weekends 在周末 They sometimes go shopping on weekends.
from time to time 不时,偶尔 I see him from time to time.
六、易错点辨析
1. always 与 all the time
always:频度副词,用在句中
all the time:时间状语短语,常放在句末
He is always happy.(他总是很开心。)
He is happy all the time.(他一直都很开心。)
2. often 与 very often
very often 表示"非常经常",频率比often更高
I often go to the park.(我经常去公园。)
I very often go to the park.(我非常经常去公园。)
3. never 的否定含义
never 本身表示否定,句中不再加not
He never tells lies.(他从不说谎。)
He doesn't never tell lies.
七、情景应用与句型
1. 谈论日常习惯
I usually do my homework after dinner.
My mother always gets up early.
2. 描述个人喜好
I often listen to music in my free time.
