那么，频率副词在句中应该放在什么地点呢？我们来看看底下的端正：

假如句子中有一个动词（比如没有助动词），我们通常将副词放在句子的正中，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.

汤姆常常开车去去公司。

Mary often asks me for help.

玛丽常常请我帮助。

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.

汤姆常常迟到。

Anne isn't usually sick.

安妮通常不怎样抱病。

Peter isn't always right.

彼得并不总是对的。

假如我们将频率副词放在句子的开头或开头表现重申，则情况并非云云。并且此端正也不实用于简略回复：

Is she usually on time?

她通常定时吗？

Tell her not to be late.

报告她不要迟到。

Yes, she usually is.

是的，她通常是。

She never is.

她向来不。

假如句子中有多个动词（比如助动词），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/助动词或模样形状动词/副词/主动词/谓语

I can never forget his name.

我向来都不会忘记他的名字。

Anne doesn't usually smoke.

安妮通常不吸烟。

The children have often complained about the playground facilities.

孩子们常常埋怨游乐场的办法。

例外：

在含有“have to”的句子中，频率副词位于一切动词之前：

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.

我们常常要等公用汽车。

She never has to do any housework.

她从不做任何家务。

为了表现重申，我们可以将频率副词放在句子的开头或开头。

起首，把它放在最初是很少见的。我们通常只在我们忘记把它放在开头时才把它放在开头。

adverb / subject / main verb / predicate

副词/主语/主动词/谓语

Sometimes we go to school by bus.

偶尔分我们乘公用汽车上学。

Often he waits for her after class.

他常常在课后等她。

subject / main verb / predicate / adverb

主语/主动词/谓语/副词

We go to school by bus sometimes.

我们偶尔乘公用汽车去学校。

They like to watch TV often.

他们常常喜顺眼电视。

例外情况：

“Always” 不克不及放在句子的开头或开头。

“Never”,“seldom”,“rarely”不克不及放在句子开头。他们只用于“报告”的句子开头。然后他们必需依照疑问句的词序：

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

从未有过比这更好的机会来克制我们的不合。

Rarely do we have an opportunity like this.

我们很少有如此的时机。

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?

你常去影戏院吗？

Do they usually come late to class?

他们常常上课迟到吗？

例外：

“Never”,“seldom”,“rarely”以及带有否定涵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.

他们不常常去影戏院。

Peter doesn't normally want to come with us.

彼得通常不想和我们一同来。
