Write a composition about falling objects +0 10O Grade two.

1. My view on preventing falling objects from high altitude is: the years are long, the waves are flickering, and the bubbles gather and disperse ... In the long history of China for thousands of years, it has gone through many vicissitudes, from drilling for fire, from rusty machetes to gunpowder guns. Today's development changes with each passing day. In the 1980s, low-rise bungalows were long gone, replaced by high-rise buildings and skyscrapers, which were numerous and dazzling. ...

Recently, the "So-so" broadcast on the science and education channel caught my attention, especially the latest issue of "Falling Objects from High Altitude", which benefited me a lot and gave me a new understanding of falling objects from high altitude. ...

In the program, the verifier tests at different heights. When the verifier opened the window on the eighth floor, in an instant, the cold wind roared in, which was very dangerous. I saw the reporter's hand holding the nail shaking outside the window. The nail is sharp and cold, which is very scary. What will happen if you accidentally get hit? The verifier released his finger with doubt, and it began to rain with nails. One nail after another fell vertically, and a pit appeared where the nail was hit, which was daunting.

When tested in 14 layer, the change of gypsum is surprising. As the nail went down steadily, the flawless plaster with a swish was riddled with holes, which made people tremble with fear. ...

But there are such things in life. Some people with cleanliness are too lazy to throw them into the trash can and out of the open window. It may be convenient for them, so can they ignore the danger of others?

Life is beautiful because it is short. A short and beautiful life, you should make good use of it and cherish it. ...

2. Ninth grade composition

Of course, because it is a high-rise building and parabolic behavior belongs to instantaneous behavior, it is difficult to find or monitor dead corners in time by these means, so the fundamental solution is to strengthen the quality of the owners themselves.

Second, fulfill the obligation of publicity and reminder. In order to strengthen the owner's own quality, the property management company can carry out regular publicity in the publicity column to inform the owner of the hazards or related cases of throwing objects at high altitude, so as to attract the owner's attention and remind all owners to supervise. Some children at home lose things unconsciously. Property companies can regularly issue some information to remind adults to pay attention to education and supervise children's behavior. Some owners decorate at home, and the decoration workers directly throw the decoration garbage out of the window for convenience. As the supervision department of decoration, the property management company should remind the decoration workers and owners to sign the safety responsibility letter before the decoration enters the site, and such incidents are strictly prohibited.

In addition to the dangers caused by parabolic objects in the owner's home, there are also hanging objects and falling objects caused by falling objects in the air caused by public areas or external factors, which are all issues that property companies attach importance to. What measures should be taken to deal with these problems? There are several kinds here.

1, to avoid falling objects caused by natural forces. In windy weather, the property management company should know the weather information in time, check whether there are any potential safety hazards in public areas, close the windows of public areas and put down items that may be blown down by the wind. Remind the owner to go out and close the window to avoid the flowerpots and other things placed on the balcony being blown off by the wind.

2. Avoid placing shelves and hanging items on the external walls of public areas. The most common shelving and hanging objects in residential areas are flowerpots on balconies, outdoor air conditioners and bay windows. The property management company shall promptly remind the owner to place and install according to relevant requirements.

Third, take protective measures when working high above the ground. When the property management company carries out aerial work such as aerial maintenance and external wall cleaning, it shall take protective measures to prevent articles from falling carelessly, and set up signs to remind passers-by to bypass or arrange special personnel to guide pedestrians during the operation.

Fourth, pay attention to the maintenance and conservation of public areas. In many cases of personal injury or property loss caused by falling objects from high altitude, there are also many accidents caused by damage or falling of public facilities, which reminds property management companies to do a good job in daily maintenance of equipment and facilities, so as to avoid damage to owners caused by falling of public facilities such as external walls, glass and windows in public areas.

Fifth, avoid risks. It is suggested that the property company buy public liability insurance, and when the damage is caused by negligence and negligent behavior, the economic responsibility will be transferred to the insurance company to avoid heavy losses.

In our daily life, there may be many dangers caused by falling objects or falling objects that we could have avoided. Here, we advocate property management companies to do meticulous work, find potential safety hazards from trivial matters and take precautions in advance. After all, ensuring personal safety and property safety is the top priority of property management.

It is not easy to see waterfalls in the second grade. We must visit Wuxie Reservoir by boat. The mountain looks like flawless green jade from a distance, and there is clear water flowing under the mountain: when it is quiet, it looks like a beautiful mirror; When moving, the water surface is full of waves ... surrounded by peaks, just like the "Yangtze River Canyon".

The cruise ship took us to the dock and we went up the hill along the stone steps. There was a loud noise in the distance, and I think the waterfall is just ahead. Sure enough, without climbing a few stone steps, the first discharge came into our eyes, and the waterfall rushed down like a silver satin or veil. When the wind blows, smoke is like fog, water drops fall like Bai Mei, and it is drizzling.

There are many tourists in the swimming pool. Some of them are catching small crabs to scare their relatives and friends. Some are splashing water to play; Some people are taking pictures as a souvenir ... I couldn't help it anymore, so I took off my shoes and got into the water to have a good time. Everyone is experiencing the harmony of nature with laughter and splashing water.

In order to see the other four beautiful faces, we continued on our way, but this time it was not as easy as the first one. The stone steps climbed steeper and steeper, and I was sweating profusely. I even used the "dog crawl"! We finally appreciate the other four leaks, and the second leak is as witty as a little girl; The third drain is like a white snake, lying on the cliff; The fourth drainage ditch is like a straight jade belt, built on a cliff several meters high; The fifth drainage ditch drips gently like a bead curtain.

The beauty of Wuxie lies in that the waterfalls in the same vein present five different styles in different positions. It's really varied and unique, and the picture is wonderful.

One day in the summer vacation, my parents took me to the swimming pool and asked me to practice swimming there first, then I signed up for a swimming class.

I thought: the way the aunts on TV fell into the water is really beautiful. I will come once. I put on my glasses and took a life buoy. I went to the deep water area and jumped away.

Unexpectedly, my body couldn't turn around, and the lifebuoy didn't hold steady, so I sank into the water at once. I grabbed the lifebuoy in a panic, but it was too slippery to catch! Fortunately, I have been holding my breath and running fast in the water. I jumped up before I stopped

That was close! The second time, I ran and jumped, but I didn't expect to succeed and didn't jump in. I also used the "high wind run" to brush past others and flew into the water.

Before I sank, I swam to the deep water area by rotating my hands and flapping my feet up and down. Took a deep breath, spit the bubbles in the saliva, and grabbed the ladder to breathe.

I suddenly wanted to play a prank, trying to pull my mother down and get her up again, which scared her. She put on her swimming glasses, lowered her head and chased me below.

I can't breathe. I jump, I breathe, so does my mother. I suddenly feel that I can't go on. My mom pulled me down.

I put my "frog jump" on the water, and then I switched my "Squirrelflight" feet up and down. I put my hand back, finally put my hand in front, and finally I can move freely. This is really interesting.

5. Pay attention to the composition of things 15o The ancients said, "A clever woman can't cook without rice." . Indeed, even the best chef can't make a satisfactory banquet without a variety of dishes and spices. The same is true of writing exercises. We must solve the problem of writing content, that is, materials, in order to fundamentally improve our writing level and ability.

It is a hard and long-term job to accumulate writing materials. As a primary school student, a very important way and method to accumulate writing materials is to develop the habit of observing things around. However, in daily life, the phenomenon of turning a blind eye and turning a deaf ear can be seen everywhere. Our school once inspected the implementation of the code of conduct: on the way from the school gate to the classroom, students consciously placed several very obvious illegal items, such as a broom head, a piece of paper, a rag and a dropped stool.

Then let the students walk over one by one. After testing, less than one fifth of the students can handle these projects correctly.

6. Fire, electricity and falling objects: 300 words fire, electricity and water. We have been used to this kind of "three defenses" since childhood, and we don't need to say much to know how important it is. There are many fires and disasters caused by hydropower all over the country every day. Think about it, how many people were killed! It is because of our negligence that we will hurt ourselves and others at the same time. Disaster happens to everyone, regardless of wealth, gender and age. If you lack due vigilance and don't know the basic safety knowledge, then once the danger comes, the bad luck you might have avoided will come unexpectedly. Some students have many hidden dangers, especially in fire prevention, electricity prevention and waterproof safety, which are mainly manifested in: poor awareness of safety responsibility, fluky psychology, lack of awareness of safety prevention and self-protection; Playing with fire, water and electrical appliances in violation of discipline; Carrying kindling and playing with fire in violation of discipline; Setting off firecrackers in festivals does not pay attention to occasions; Bring fire into the mountain forest area to play during the closing period; Use fire, electricity, oil, gas, etc. Violation of operating procedures.

Safety first! Only by paying attention to safety and caring for life can we try our best not to regret what we have done. There is only one life, and there is only one life. Pay attention to safety and make life colorful. Otherwise, it will hurt not only you, but also others and your family.

7. A 200-word composition for the second grade of primary school 10. At this moment, the sky and clouds, mountains and water are white.

It's all white except hazy or hazy. On the willow tree with all the leaves, it is covered with fluffy and shiny silver bars; Evergreen pines and cypresses in winter and summer are full of fluffy pines and heavy snowballs.

It is really "like a strong wind in spring, which blows at night and blows open the petals of ten thousand pear trees". The snow is getting bigger and bigger, and it gradually turns into a small white snowball.

Clouds and clusters of snowflakes fly down, like countless broken cotton balls falling from the sky. I can't help thinking of Xie Lang's saying that "the difference between salting and air can be simulated" and Xie Daowen's saying "If catkins don't rise from the wind".

Yes, when the wind blows, it seems that there are countless balls moving irregularly in the air, which reminds me of the movement state of molecules in science. It is spectacular. Snowballs covered branches, roads and crops, bent branches, sent a warm white coat to crops and put a white cloak on roads.

Overlooking the distant mountains, it is also a snowy country. Seeing the scenery of a water town in the south of the Yangtze River like Zhejiang, where thousands of miles are frozen and Wan Li is snowing, people can't help but wonder if they arrived in the northeast in an instant.

The snow came in such a hurry that it left in a hurry. After a while, it began to get smaller.

Slowly, it gets smaller ... until it disappears. The world between heaven and earth is still a silvery white world, and you can't tell the southeast from the northwest.

The snow has stopped and left. There is still snow on the roof, as if it were an elegant veil ... Yes, the snow has gone, it came quietly and left silently, leaving only surprises for people.
