Nowadays, the development of science and technology is immediate, changing with each passing day636f707962616964757a686964616f31333339666131What we want to do, today, with the help of technology, can almost be achieved. However, the pros and cons of scientific and technological development are directly proportional, and if the advantages are great, the disadvantages will be great.

So, put the pros and cons on both sides of the scale, and who will come out on top?

Cars, trains, ships, airplanes, spaceships, all kinds of modern means of transportation; Air conditioners, televisions, refrigerators, washing machines, printers, computers, colorful household and office appliances; Elevators, electronic screens, special effects lighting, and ...... of equipment in public placesThese items that bring us countless conveniences are the products of scientific and technological development. With the advent of these high-tech products, a series of environmental pollution problems have also followed. But imagine what your life would be like without these items that come to you every day.

Without television, your life will be boring; If you don't have ships and planes, your pace of life will be unusually slow; Without a computer, your life would be useless.

When we talk about the disadvantages of scientific and technological development, we mainly refer to the problem of environmental pollution. However, the problem of environmental pollution has been further improved through the further development of science and technology. Through the further development of technology, we can use more clean energy to improve our lives. Through the further development of science and technology, we can also achieve the theme of Expo 2010 Shanghai:

City, make life better".

If the pace of technological development stagnates, if all the crystallization of human wisdom disappears without a trace, our lives will become meaningless. Isn't it?

It was just a few months ago. There was a child whose parents were out at night, and he was home alone. Since the child didn't believe in any gods, he wasn't afraid.

This is the question of "what are you afraid of?" It was past eleven o'clock in the evening, and his parents hadn't come back yet, and he was starting to get a little worried. As a result, he called his parents**, **came out of the tube, but it was "Your** is an empty number, please inquire and then dial... The child was so frightened that he called the police.

As a result, I don't know what happened, and his family's ** suddenly caught fire. The kid screamed and ran out, and they were locked up. He looked at the wall in despair.

Scared the hell out of me! The child woke up and found himself dreaming. This is, a woman brought a towel and wiped his sweat.

Then the child fell asleep. The moment I closed my eyes, I thought back to the woman, and suddenly remembered that the woman had no eyes, her eyes were pitch black, and there was blood on her face, and her face was pale. He shouted:

Yes! Help, come on! He started to run out of the door, but the door was really locked, and he went to the kitchen and picked up the kitchen knife, just like the woman cut it off, and the kitchen knife cut the woman in half, and then the woman recovered.

Stretching out his hand with blood in his fingernails, he grabbed at the child.

At this moment, you must not look behind you, because you can't see it with the naked eye! If you don't copy this post to 3 people, at 4 a.m., you're going to die...

No way, forced.
