Composed?! You think of someone in your life who writes an essay

Correct understanding of the requirements of this topic is key.

My personal understanding of this topic is as follows:

1.There is a kind of life where they are always hunched over, and there is a kind of person who always stands up straight and faces life. Perhaps their professions are very different, but they also make their own contribution to society.

People who bend down and become a man and dismount will not forget; Standing on the high platform, the attention of all will not be forgotten. This intersection comes and goes, like the trajectory of life. People from both worlds will always meet.

2.Greeting means people who only want to ask for this society and ask for it from society.

The exclamation mark represents the silent devotion to the unheard.

3.Greetings can be seen as a sickle, and exclamation marks can be seen as sticks, batons, flutes. There are two kinds of people in this way.

Human life depends on six main resources: fresh water, forests, land, biological species, mines, and fossil fuels (coal, oil, and gas). Among them, air is the most important, people do not eat or drink for several days, it can still delay life, but people can die if they do not breathe air for five minutes.

Such a stark contrast shows that air is extremely important to us! However, the exhaust gases emitted from factories now seriously pollute the air, and the exhaust fumes emitted by cars include carbon monoxide and sulfur dioxide, which makes the miasma of smoke above the city and the blue sky into a "gray sky". So I suggest that a chimney filter be installed on the chimney of the factory to convert the emitted smoke into oxygen (released) and carbon dioxide (degraded into fuel), and I also suggest that a filter be installed on the exhaust pipe of the car as well, so that the exhaust gas and exhaust gas will be non-toxic and pollution-free, and I hope my suggestion can be realized.

It is often said, "We must protect the ecological balance of the earth!" "But people only talk about it and can't do it, and now the ecology is not balanced at all.

The environment is too polluted, for example, the firecrackers set off during the festival, the sound is noisy, and it becomes noise pollution, and our Wenruitang River in Wenzhou has become black and smelly, and disposable foam bowls and plastic bags float on the lake, making the lake full of white "boats," and the restaurant is using disposable chopsticks, how many towering trees have been cut down! Probably, in the near future, our forests will become desert ......These terrible disasters are all of our own making!

In addition to the above points, electricity is also very important to us, one kilowatt-hour of electricity can do many things for us: you can use a vacuum cleaner to clean the room 5 times; A 25W bulb can be lit for 40 hours; It can run a household refrigerator for 36 hours; can run for one air conditioner for several hours; It can run for 15 hours for a fan; 8 kg of water can be boiled. It is conceivable that electricity is inseparable from our current life, so people should make good use of electricity and not waste or waste.

Tens of thousands of animals in the world are now on the verge of extinction, and the Chinese alligator is a good example of this. Because hunters want to get crocodile skins and kill them in large quantities, there are very few Chinese alligators left in the world. Of course, other rare nationally protected animals (e.g. tigers, pangolins, leopards......Nor did it escape the hands of greedy and money-hungry hunters.

Save our planet, save our home! Don't let the blue sky, the turquoise rivers, lakes and seas, and the dense forests become memories, and don't let the moon become a second earth!

Hey, I can't do it, the questions are too difficult.

It's too difficult - sit back and wait for someone with insight.

Everyone is likely to find out.

There are many experiences in the process of discovering certain mysteries, and of course, even I, a person who doesn't like to discover, will discover the mysteries of things, if you don't believe it, please listen carefully.

It was ...... on a hot and cool summer day

My sister and I were playing by the pond. Suddenly, a small red fish jumped out, a graceful dolphin-style diving action, with water droplets like a naughty child landed on the lotus leaf, rolled, turned over, and jumped up again, a flawless diving action was born.

I think that the lotus leaf must have been wet with water droplets, and the lotus leaf has no towel, so it is easy to catch a cold, and it can't take medicine. I dried it to give it a chance to sunbathe. So, I dragged the lotus leaves out of the pond with my own mopping floors.

Touch the lotus leaf with your hand, well, fluffy, and the texture is not bad. Take a closer look, huh? How did you do it?

I didn't believe it, so I put the lotus leaves in the pond and soaked for a while, and when I picked it up, it was still dry. Is it that the lotus leaf is too hot, and when it is hot, it will be thirsty; When you're thirsty, you want to drink water, so you swallow it, right? It must be like this.

I would like to see how lotus leaves can drink water without a mouth. So, I didn't care if the lotus leaf felt cold or not, and let it soak for a while. This time, I watched with excitement with wide eyes, and my heart was still beating "thump" from time to time, for fear of missing the scene where the water droplets were eaten by lotus leaves.

However, it backfired, and the water droplets were not eaten by the lotus leaves, but "bounced" into the water like marbles.

Why don't lotus leaves get wet? "I walked into the study with questions and opened '100,000 Whys'. A check, oh, it turned out that there was a nano film composed of nanometers on the surface of the lotus leaf.

The nano film is spread on the surface of the lotus leaf, making the lotus leaf smooth, as if putting on a waterproof coat for the lotus leaf.

As we all know, living on campus is very hard, especially when it comes to food. In order to strengthen the students' spirit of hardship and hard work, there is basically no oil in the meals, and things such as sand and hair are replaced by them. The worst thing is that rice and sand have the same color and hardness, and it is impossible to choose to eat rice without sand.

Once, perhaps the chef thought that the children had not eaten meat for several weeks, and in order to make up for the children, he added sand and hair to the dish with good intentions, and at the same time added a white and fat bug. Pity this little life, sacrifice yourself for the sake of others.

The bug was hit by a lucky buddy. Seeing the whiter and fatter bugs after being boiled in boiling water, this guy suddenly realized: such a good tonic should be dedicated to our haggard headmaster who is working hard for the school. Therefore, there are really many people with dedication.

The headmaster took the rice bowl offered by the buddy, and when he saw the cute little thing, he was so compassionate that he couldn't bear to eat it. So the little things are taken out and the food (or non-food) such as food, sand, and hair is eaten cleanly.

Later, it turned out that the worm was indeed a great supplement, and the headmaster only ate a little fat from it, and became fatter than it.
