When I was in junior high school, I studied that set of textbooks, which were from a long time ago. That article was in the "Junior High School English Volume 5" at that time.

The main idea of ??the story: A group of farmers settled in Salt Lake City, growing crops and living. One day, a swarm of locusts suddenly flew from the sky and began to eat the farmers' crops. Just when the farmers didn't know what to do, a group of seagulls suddenly flew from the sky and ate the locusts, saving the farmers. The farmers built a monument to the seagulls and decided not to harm the seagulls from now on.

The seagulls of Salt Lake City

Salt Lake City is a beautiful city in the west of North America, which was founded over a hundred years ago. At that time, a group of men, women and children arrived at a valley with high mountains all around it. They had traveled a long way. They had begun their journey far away in the east. After they had crossed the mountains, they found the valley. In the middle of it there was a salt lake. This was where their city now lies.

The land seemed good, and they decided to stay there. They built their homes, and made their farms, and planted their crops. people had to work hard on their farms. If they did not grow enough food, they would have nothing to eat.

One day while they were working in the fields, some farmers saw something strange in the sky. "what is that?" asked one of them.

"Where?" asked another farmer, as he stopped to look.

"Over there," he answered.

They saw something coming towards them. It looked like a cloud, but it was too low in the sky. As they watched, it came nearer and nearer. Suddenly a shout went up: “Locusts! Millions of locusts!”

Every one stopped working, and looked at the sky. They were all frightened, because they knew what locusts could do. They had never seen so many of them before.

In no time the locusts came down and started eating their crops—the wheat, the vegetables, even the grass, and the leaves on the trees.

Everyone—men, women and children—tried to fight against the locusts. They tried everything, but while they were killing locusts in one place, millions more arrived in another.

What could they do?

Suddenly they heard a great noise. They looked up into the sky and saw another great cloud coming towards them. To their surprise, they saw not locusts, but seagulls. The farmers cried out, “They have come to eat what the locusts have left!”

But they found that the seagulls had come to eat, not their crops, but the locusts. Usually, the seagulls lived near the sea. But they had seen or smelt the locusts and had come to eat them. Now they were eating the locusts. In a short while they ate up millions of them. The farmers' crops were saved!

The people were very thankful. They decided that from then on no one should ever kill a seagull . And today, if you go to Salt Lake City, you can see a monument with seagulls on top of it.

I am deeply impressed by the text Salt Lake City Seagulls. I don’t remember it happening long ago, and the original text has also been released. No long long ago. Before I answer your question, does your mother still remember the gist of the story? If she can't remember, then maybe she remembered the long long ago wrongly. Otherwise, the article she studied was a different article. If that's the case, then I don't know. This article I learned has been learned by everyone in their 30s now. Haha, it was a unified national textbook at that time
