2.
频度副词在句中的位置

E.g.

never
eat
junk
food.

sometimes
very
busy.

say
a
word.
(2)有些频度副词也可位于句首，但表示不同含义
sometimes
常位于句首，和位于句中区别不大。
E.g.
Sometimes
Jack
plays
computer
games.
often
用于句首时，通常表示强调，且其前一般有quite，very
修饰
E.g.Very
often
he
goes
online.
Usually
也可位于句首，其前不用修饰语。
E.g.
Usually
my
father
goes
up
early.
Always
一般不用于句首，但可以用在祈使句中。
E.g.
Always
remember
this.
3.
对频度副词提问时，用how
often

---Once
a
month
