I like little dolphins. Little dolphins are the cleverest. They can be good assistants to scientists. They can imitate poetry.

Dolphin, not laughing.

There is a science class on Wednesday afternoon.

Teacher Wang said

Dolphins didn't really laugh.

It just looks like it's laughing.

If the corners of my mouth

Like a dolphin, it keeps rising.

Grow close to the eyes

Does everyone think I'm laughing?

If I hadn't laughed

But it looks like laughing.

What strange things will happen?

Live in a noisy aquarium

I thought I was laughing, too

There is nothing to eat.

I thought I was laughing, too

Practice heading every day.

I thought I was laughing, too

Endless performances every day.

I thought I was laughing, too

When you are sad, you seem to be smiling.

When you are angry, you seem to be laughing.

I seem to be laughing when I am sad.

When you cry, you seem to be laughing.

There is a science class on Wednesday afternoon.

Teacher Wang said

A dolphin that seems to be laughing.

Actually, I've never laughed.

Such a dolphin

What kind of mood will you have?

If the dolphin's mouth becomes u-shaped,

world

Will it be better?
