频度副词

表示动作频繁程度的副词叫做频度副词。常见的频度副词

有always,sometimes,usually,often,never等。

★常见的频度副词按频率大小排列如下：always(总是100%)

usually(通常80%-90%)often(经常50%-70%)

sometimes(有时20%-40%)never(从不0%)。

★频度副词的位置：频度副词通常放在实义动词之前，be动

词、助动词或情态动词之后，但有些频度副词如often,

sometimes等位置比较灵活，还可以放在句首或句尾。

e.g.Mybrotherusuallyhasaneggforbreakfast.Samisalwayshappy.

Youshouldalwaysgotoschoolontime.

Herdadsometimesgoestoworkonfoot./Sometimes

herdadgoestoworkonfoot./Herdadgoestoworkon

footsometimes.

Shecallsmeoften.

注意：如果句子中有两个助动词，频度副词通常放在第一个助

动词之后。

e.g.Wehaveneverbeengiventhechancetotalktohim.

★当对频度副词及表示事件发生频率的短语提问时，常用howoften。howoften意为“多久一次”。

e.g.Isometimeslistentomusicintheevening.(对划线部分提问)

→Howoftendoyoulistentomusicintheevening?
