Flashlight is a kind of daily necessities that people are very familiar with. Almost every family has it and everyone has used it. When I was a child, it was a great honor to have a flashlight. At night, I took it out and turned on the switch to shine in the distance, like a white column, which was very beautiful and powerful.

At first, the flashlight at home was old-fashioned. There were children with thick and thin arms and more than 20 cm long. Install two No. 1 batteries. In the last century, there was a shortage of electricity and saving everywhere. Many places where lights should be turned on are not turned on, and areas where lights should be turned on are not turned on. The function of flashlight is highlighted. For example, there are three shifts at home, and there is a flashlight on the middle shift and night shift. It's very convenient. Not afraid of night, not afraid of rough roads, not afraid of meeting bad people, the family is also at ease. At that time, our courtyard used a public toilet. The two huts were behind a courtyard wall. The light was poor. When the light bulb broke, it was not replaced in time, and it was dark. Many people go to the bathroom to pick up a box of matches and scratch to identify the situation. The weather was fine and OK. In case of wind and rain, the match couldn't be lit at all. At this time, the flashlight is used.

As a child, there were no more toys to play with. He often took out his flashlight, caught a cricket, dug out a bird's nest, drilled a cave, and played hide and seek. Sometimes they get together to take photos everywhere and "fight" with a light column is much better than playing with rolling "iron rings" and "slingshot". But this kind of play is mostly short-lived. Because it consumes batteries. A No. 1 battery costs more than 20 cents. The flashlight needs less than two sessions. It's fun to play. You can use almost all the electricity in one night. Adults will never let children be so extravagant. So some people's flashlights are locked in drawers by adults, so they don't have to take them out.

Later, the flashlight was upgraded, not only the performance was improved, but also a new style. Pocket size is one of them. The thumb is thick and thin, with two No. 5 batteries. The appearance is very fine and beautiful. It's very convenient to put it in your pocket. I've always expected such a flashlight, but it's hard to see in the market. One year, a rural relative came to the family and said that there was a problem in their village supply and marketing cooperatives. I was so happy that I begged him to bring one when he came next time. When he came back, he spread his hands and said: it's out of stock. At that time, I didn't understand what it meant to be out of stock, and I chased him to inquire. It's funny and pathetic.

When I was in college, a man in the dormitory next door brought a big flashlight with four batteries, which came out directly through the glass like a searchlight. Later, I learned that his father was engaged in defense and had such special tools. When there is a power failure, they hang the flashlight on the ceiling. It's like the day. They should read and write. It's not affected at all. It's really enviable.

Now there are more and more kinds of flashlights, and the performance is changing with each passing day. Children are no longer rare and used as widely as before. But every family still has it, which is a good thing. Youdao is to be prepared. At the critical moment, the flashlight plays a great role!
