语法精讲精练二
1.频度副词的定义与分类
频度副词(Adverbs of Frequency)用来表示动作发生的频率,回答“How often.?”的问
题。常见频度副词按频率从高到低排列如下:
频度副词
大致频率
示例
always
100%(总是)
I always get up at 6:00.
usually
80%(通常)
He usually walks to school.
often
60%(经常)
She often reads books.
sometimes
40%(有时)
We sometimes play football.
seldom
20%(很少)
They seldom eat meat.
hardly ever
5%(几乎不)
I hardly ever watch TV.
never
0%(从不)
She never lies.
【中考考点】注意频率的递减顺序,以及seldom/hardly ever/never常用于否定含义,
但在反意疑问句中视为否定。
2.频度副词在句中的位置(三大核心规则)
★规则一:放在be动词/助动词/情态动词之后
结构:be/助动词/情态动词+频度副词+实义动词(如有)
例:
He is always happy.(be动词后)
I have never been to Beijing.(助动词have后)
You can always call me.(情态动词can后)
★规则二:放在实义动词之前
结构:频度副词+实义动词(注意:实义动词前无be/助/情态时)
例:
She often goes shopping.
They seldom eat outside.
★规则三:sometimes可放在句首、句中、句尾(灵活)
例:
Sometimes I walk to school.
I sometimes walk to school.
I walk to school sometimes
【易错点】
①always不可用在句首(祈使句除外),never可放句首加强语气。
②否定句中频度副词通常放在否定词之前或之后?
Idon't often eat fast food.(not在often前)
I often don't eat fast food.(不常见,但语法可)
中考常考dont/doesn't/didn't+always/often等结构,意为“不总是/不经常”。
3.频度副词与疑问句
对频度提问用How often..?
例:一How often do you exercise?
-I usually exercise three times a week
回答方式:
I可直接用频度副词:always/never等
I也可用具体频率短语:once a week/twice a month/every day等
【中考考点】注意区分How often(频率)与How long(时长)/How many times(次
数)。
4.频度副词的比较级与最高级(拓展)
部分频度副词有比较级和最高级(中高考偶考):
often-oftener /more often->oftenest/most often
seldom/never/always一般不用比较级和最高级。
例:He comes to school more often than I do.
5.易混辨析
always vs usually:always表示“总是”(毫无例外),usually表示“通常”(大多
数情况)
sometimes vs sometime
sometimes是频度副词,“有时候”;sometime是副词,
“某个时候”
hardly ever vs hardly:hardly ever是“几乎从不”,hardly是“几乎不”(程度副
词),后面接ever则加强否定。
例:I hardly understand.(几乎不明白)
I hardly ever go to the cinema..(几乎不去)
