1. A composition describing swallows. In spring, swallows fly back. In spring, who is flying in the fields?

There are cuckoos flying.

Who is flying in the fields in spring?

The cuckoo is flying.

Who is flying in the fields in spring?

There are larks flying.

Who else is flying over the fields in spring?

Swallows are flying freely over the fields.

The swallow was tired of flying and landed on the telephone pole, vaguely looking at the scenery of the field.

On the field, there are one patch of green, one patch of green, one patch of yellow, and only one old ox pulling the plow.

The old scalper seemed to be fascinated by the scenery of the fields. He stared at everything in front of him for a long time. If the farmer hadn't patted him, he might not have been able to turn his head.

In the sky, swallows are in groups of three and five, as if they are starting a flying competition!

Some flew from the pine tree here to the willow tree there. The tip of their tail occasionally touched the water, and they saw ripples rippling around in circles.

Some swallows stopped beside the flowing stream, chirping non-stop, as if to say: "Your water is so clear, like a mirror, can you let me preen my feathers here?" Yes

Half of the swallow's body is already in the river, as if taking a bath there.

That time, I witnessed with my own eyes the process of swallows building their nests under the beams of my uncle’s house.

I was playing in the yard when suddenly two swallows flew to the house, circled in front of the house, chirped, and then landed on a tree in front of the door to look around.

They seem to be saying that this place is so nice, why not let us build a nest here!

I saw clearly that they were a couple, one male and one female.

Two cute little swallows, wearing gray coats with white shirts exposed on their chests, have bright little black eyes.

After a while, they flew away, which I felt a little sorry for.

But I still wait patiently, hoping that they will come again.

After a while, the two little swallows flew back, this time with mud in their mouths.

I was overjoyed because I knew that the swallow was going to settle down in the corner of my uncle’s house.

I saw the swallows sticking mud to the corner of the wall, one flew out, and the other was still sticking.

After a while, that one flew back with mud in its mouth, and this one went out to hold mud again, and they continued to make nests with mud in their mouths.

After an unknown period of time, the little swallow finally built its nest into a semicircle, with both ends of the semicircle tightly connected to the corner of the wall.

The little swallow flew out again and flew back to make another circle in the semicircle.

One day, two days, the little swallows circled more and more, and the nest became bigger and bigger. It was almost completed. There was only one door left in the front, and finally it could only accommodate the swallows.

They also brought in many leaves and feathers and prepared their nests.

When it was done, I saw the pair of little swallows getting into the nest, sticking their heads out, and shouting excitedly.

I'm also happy for their success.

Although the little swallow's nest is not the most beautiful masterpiece in the world, it is built bit by bit with small mouths. It is the crystallization of sweat and hard work, the crystallization of wisdom and perseverance.

Ah, little Yanzi, you are an amazing construction expert in the world.

In spring, the swallows fly back. Have you noticed it?

2. A composition describing a swallow. A body of jet-black feathers, a pair of scissor-like tails, and a pair of strong and brisk wings make up such a lively and cute little swallow.

The little swallow's black and shiny feathers seemed to be oiled, and its white belly looked like it was wearing a white shirt.

Swallows are so beautiful when they fly.

Those long and narrow wings, that forked tail, all look like they were painted by the most skilled painter, and there is no single pose that is not beautiful.

In the tender blue sky, there are a few thin lines connecting the poles, and there are a few small black dots parked on the lines, which are swallows.

How like a piece of music waiting to be played!

A swallow's nest is like half a rice bowl, with the top opening open and covered with soft feathers, hay and soft debris.

Sometimes the flocks of swallows are like long swords that sweep across the sky, stabbing across the sky; sometimes they are like a swarm of fighter jets, swooping in, flying and echoing in the air around the place where they stay.

Swallows are still swarming in the sky, which always has dotted lines.

The flight of swallows gives people a feeling of lightness and grace, and the arrival of swallows gives people a sense of auspiciousness and tranquility.

Swallows are the messengers of spring.

The swallow has a scissor-like tail and flies diagonally through the air.

Spring swallows fly back and forth, filling the air with murmuring sounds.

Swallows know their old owners. Every year when the weather starts to get warmer, a pair of swallows will return to the old hall of my house.

The young couple held grass stalks in their mouths and mud balls in their mouths, and worked together to build a small nest.

They chase moths, catch caterpillars, and share food with swallows with yellow fur and mouth.

The swallow's nest is never fortified, and it spends its days and months with its owner, sipping, squeaking, chatting and laughing, and is very happy.

Swallow, Swallow, I know you became so nimble only through labor!

I also know that you are working and absorbing the light of the sun, which makes your black feathers so shiny; even your fiery red lips are painted with the color of the sun to become so gorgeous!
