20 words in grade one are wonderful enough to come up with the shortest composition in the world.

When the last person on earth was sitting alone in the room, there was a knock on the door that I hadn't heard for a long time. He knew that his end was coming. ...

This is a double agent. And the President of the United Nations. At that time, it was he who created the twentieth world war. At the fiercest moment of the twentieth world war, Martians had the opportunity and finally occupied the earth. It turns out that in 2 100 years, people have confirmed that there is life on Mars. Moreover, the technology of these lives is much more advanced than that of the earth. It is natural for the United Nations to find aliens. The president of the United Nations ordered people to take gifts to visit Mars. But Martians are very cold. They even want to occupy the earth. Because Martians have a high reproductive rate. Such delicious food is hanging in front of their eyes. Who can not be greedy? Of course, this idea, the earth people don't know. The President of the United Nations responded positively to this attitude. And said: "Martians are more advanced than our technology, and they should have this right." In fact, he has guessed the Martians' intentions, and he wants to please them. So he persuaded people not to trust Martians, and they humiliated us. This caused two kinds of ideas, which led to disputes. Coupled with the encouragement of the president, the twentieth world war began and achieved good results. Martians easily occupied two continents and three oceans. The President of the United Nations keeps sending everything on the earth and destroying it step by step. But Martians are not fools.

Someone knocked at the door. The president's hand holding the doorknob has been shaking. The door finally opened and a tall and burly Martian came in. "Mr. President, I can gently push, open the door, and then twist your head off like a leaf. We didn't do it out of courtesy. You should also know what will happen if you don't listen to us. Now, please come with me to see the leader. " Life on mars persists. The president's hand is so tight that he will ask the leader to let him live anyway.

The president was taken to a room as white as snow, with a screen inside, and the Martian leader turned his back on him. "Mr. President, you finally came." The leader's deep voice came out: "In order to make you happy, we decided to let you meet your compatriots on the earth. The so-called' going to the west'. You will be well treated when you get there, won't you? " The humor of the leader of Mars is terrible for the President. Before he could make any noise, a Martian took out a laser beam pistol. Silently, the heart of the last man on earth stopped beating. ...
