频度副词的用法
表示频率的副词有:
always,.
usually,.
often.,
sometimes.
Hardly,ever,
never.,once等。它们通常放在助动词之后,实义动词之前、在句中作状语。它们各自所表示的频率高低不同。下面我们着重说明如下
★
always
always意为“总是”,与进行时态连用时,可以表示赞扬,也可以表示讨厌等感彩。例如:
(1)I
shall
always
remember
my
first
day
at
school.我将永远记住我上学的第一天。
(2)
He
is
always
smoking.他总是抽烟。
★
usually
usually可以指通常的动作,但是侧重已经形成的习惯,它是从已经形成的角度来说明动作。例如:
(1)I
usually
do
some
shopping
with
my
parents
on
Sundays.
我经常在星期天和我的父母一起去买东西。
(2)He
usually
goes
to
school
by
bike.
他通常骑自行车上学。
★
often
often是指经常性的动作,意思为“常常;经常”。例如:
(1)Children
don't
often
do
homework.
孩子们经常不写作业。
(2)
He
is
often
late
for
school.他经常上学迟到。
★
sometimes
sometimes意思为“有时;不时”,表示次数较少(低于
often所表达的次数),常常与一般现在时或一般过去时连用。例如:
(1)Sometimes
he
goes
to
work
by
bike,
and
sometimes
he有时候他骑目行车上班,有时候他乘公共汽车上班。
(2)Sometimes

my
parents

★

(1)
He
hardly
drinks.他几乎不喝酒。
(2)

★
never
never意思为“决不;从未”,表示一次也没有。例如:
(1)
He
never
lives
there.他从来都没有在那儿住过。
(2)
She
never
has
anything
to
do..她一向无所事事。
【模糊频度副词】
以下这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.几乎从不never从来不
例如：
On
weekends
I
always
use
the
Internet.周末我总是上网。
I
usually
watch
TV..我通常看电视。
I
often
sleep
late.我经常睡得晚
I
sometimes
listen
to
music.我有时候听音乐。
I
hardly
ever
play
computer
games..我几乎不玩电脑游戏
I
never
play
soccer,.我从不踢足球。
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.
【精确的频度副词】
以下这些频度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
次
four
times五次
five
times六次
six
tin
注意:在记忆时,我们只要记住once“一次”和
twice“"二次可以了。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,吃蔬菜。
I

once
a
week.我每周锻炼一次。
I

s
twice
a
month..我一个月吃两次麦当劳。

【其他的表达法】
