"Only those who lie in the pit forever and don't look up at the sky will not fall into the pit." An argumentative essay is 800 words.

Thales, an ancient Greek philosopher, looked up at the starry sky and observed the stars, only to find that there was a deep pit in front of him, and he fell down with one foot. The result was saved by passers-by. When he said to passers-by, "It's going to rain tomorrow!" The man smiled and shook his head, telling Thales' prediction as a joke. It rained the next day.

Some people will say that Thales only knows what is in the sky, but he can't see what is under his feet. But when people live in the world, they will always encounter some deep pits of life, and they will fall into the air without taking precautions. These are inevitable for everyone, and no one's life is smooth sailing.

Pits, turbulence ... may be encountered at any time. What we should do is to think of it as the superposition of experience after experience. Remember that the next time you look up at the starry sky, you may have a pit under your feet, so be careful to fall in.

In the twelve years of our painstaking study, there will also be many deep pits. For example, failure in exams, failure in competitions, loss of honor ... these are some unexpected pits when we look up at the starry sky of knowledge. Falling into the pit is not terrible. The terrible thing is that after falling into the pit, we don't have the courage to climb out of the pit and continue to look up at the starry sky of knowledge, continue to appreciate the bright starry sky and continue to enrich our knowledge. Let others know that we are not only so rich in knowledge in the sky, but also can see things under our feet.

After listening to Thales' story, the German philosopher said, "Only those who lie in the pit forever and never look up at the sky will not fall into the pit." Just like a frog sitting in a well looking at the sky can't see the endless sky, there is a lot of knowledge waiting for us to explore and a lot of mysteries waiting for us to reveal.

The launch of China's "Shenzhou 5" and "Shenzhou VI" are two successful examples of exploring the mysteries of the sky. Those scientific and technological talents in our country are also looking up at the stars, getting up and continuing to work hard. Imagine, if they dare not get up after falling into the pit again, and lie in the pit forever without looking up at the sky, there will be no success of Shenzhou V and Shenzhou VI, and there will be no launch of Chang 'e I.

We bravely look up at the starry sky, no matter whether there is a deep pit ahead, we must always go forward bravely.
