由“what”引导的感叹句：修饰名词（被强调部分），单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是：

what+(a/an)+adj.+n.+主语+谓语+(it

is).

如：

What

a

clever

girl

she

is!

What

an

interesting

story

it

is!

What

good

children

they

are!

What

beautiful

flowers

they

are!

What

delicious

food

it

is!

二、由"how"引导的感叹句：用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，这类句子的结构形式是：

How+adj.（adv.）+主语+谓语+(it

is).

如：How

cold

it

is

today!

How

nice

the

pictures

are!How

well

she

sings!How

hard

they

are

working

now!

三、在表示同一意义时，英语感叹既可用“what”引导，也可用“how”引导。如：

What

a

hot

day

it

is!

=How

hot

the

day

is

!

What

tall

buildings

they

are!

=How

tall

the

buildings

are!

What

bad

weather

it

is!

=How

bad

the

weather

is!

What

bright

sunshine

it

is!

=How

bright

the

sunshine

is!
