四、语法精讲：频率副词
1、定义
表示次数，频率的副词称为频度副词。常用的频度副词有always,
usually,
often,
sometimes,
hardly
ever,
seldom,
never
等。句中只有一个行为动词时，频率副词应位于动词之前；当有助动词、系动词、情态动词时，位于其后。
I
always
get
up
early.
我总是起得早。
The
workers
seldom
have
lunch
in
the
factory.
工人们很少在厂里吃午饭。
2、用法
1）常用频度副词的区别。
(1)
always
意为“总是，永远”，表示频度最高。
(2)
usually意为“通常”，即很少有例外，多用于一般现在时。
(3)
often意为“经常”，在频度上不如usually那么频繁。
(4)
sometimes意为“有时，偶尔”。
(5)
hardly
ever
意为“几乎不，很少
”，表示否定意义。
(6)
never
意为“从来没有，绝不”，表示否定意义。
以上几个频度副词所表示的频度，从高到低为：
Always(100%)→usually
→often
→sometimes
→hardly
ever
→never(0%)
2）提问频率用how
often,
意为“多久一次”。
E.g.
—How
often
do
you
cook?
你多久做一次饭？
—Three
times
a
week.
一周三次。
3、频率副词的特殊用法
always表示动作重复，表示频率最大，意思是＂总是，一直，永远＂。其反义词为never。always与进行时态连用，并不强调动作正在进行，而是表示说话人的＂赞叹、不满、厌烦＂等情绪，带有强烈的感彩，结构：be
always
doing
sth。
She
is
always
copying
the
homework.
她老是抄作业。(表示不满)
You
are
always
helping
others.
你总是帮助他人。（表示赞扬）

1.
How
often
do
you
watch
TV?

一次电视？
how
often
意为“多久一次”，用于对动作发生的频率进行提问。回答应该是频度副词或表示频率的词组，如always，usually，often，once
