那么,频率副词在句中应该放在什么位置呢?我们来看看下面的规则:

如果句子中有一个动词(例如没有助动词),我们通常将副词放在句子的中间,即在主语之后,动词之前:

subject / adverb / verb / predicate

主语/副词/动词/ 谓语

Tom usually goes to work by car.

汤姆经常开车去上班。

Mary often asks me for help.

玛丽经常请我帮忙。

频率副词通常放在“be”动词之后:

subject /be verb / adverb / predicate

主语/be动词/副词/谓语

Tom is often late.

汤姆经常迟到。

Anne isn't usually sick.

安妮通常不怎么生病。

Peter isn't always right.

彼得并不总是对的。

如果我们将频率副词放在句子的开头或结尾表示强调,则情况并非如此。而且此规则也不适用于简短回答:

Is she usually on time?

她通常准时吗?

Tell her not to be late.

告诉她不要迟到。

Yes, she usually is.

是的,她通常是。

She never is.

她从来不。

如果句子中有多个动词(例如助动词),我们通常将频率副词放在第一个动词之后:

subject / helping verb or modal / adverb / main verb / predicate

主语/助动词或情态动词/副词/主动词/谓语

I can never forget his name.

我从来都不会忘记他的名字。

Anne doesn't usually smoke.

安妮通常不抽烟。

The children have often complained about the playground facilities.

孩子们经常抱怨游乐场的设施。

例外:

在含有“have to”的句子中,频率副词位于所有动词之前:

subject / adverb / have to / main verb / predicate

主语/副词/have to/主动词/谓语

We often have to wait for the bus.

我们经常要等公共汽车。

She never has to do any housework.

她从不做任何家务。

为了表示强调,我们可以将频率副词放在句子的开头或结尾。

首先,把它放在最后是很少见的。我们通常只在我们忘记把它放在开头时才把它放在结尾。

adverb / subject / main verb / predicate

副词/主语/主动词/谓语

Sometimes we go to school by bus.

有时候我们乘公共汽车上学。

Often he waits for her after class.

他经常在课后等她。

subject / main verb / predicate / adverb

主语/主动词/谓语/副词

We go to school by bus sometimes.

我们有时乘公共汽车去学校。

They like to watch TV often.

他们经常喜欢看电视。

never什么时候学的(cannever还是nevercan)(4)

例外情况:

“Always” 不能放在句子的开头或结尾。

“Never”,“seldom”,“rarely”不能放在句子结尾。他们只用于“陈述”的句子开头。然后他们必须遵循疑问句的词序:

Never has there been a better time to overcome our differences.

从未有过比这更好的时机来克服我们的分歧。

Rarely do we have an opportunity like this.

我们很少有这样的机会。

在疑问句中使用频率副词时,请将副词放在主动词之前:

auxiliary verb / subject / adverb / main verb / predicate

助动词/主语/副词/主动词/谓语

Do you often go to the cinema?

你常去电影院吗?

Do they usually come late to class?

他们经常上课迟到吗?

例外:

“Never”,“seldom”,“rarely”以及带有否定含义的其他频率副词通常不会在疑问句中使用。

当在否定句中使用频率副词时,请将频率副词放在主动词之前:

Subject / helping verb / adverb / main verb / predicate

主语/助动词/副词/主动词/谓语

They don't often go to the cinema.

他们不经常去电影院。

Peter doesn't normally want to come with us.

彼得通常不想和我们一起来。
