Environmental Investigation Report.

Survey location: Qiandao Lake streets.

Respondent: The source of environmental pollution in Qiandao Lake.

In recent years, with the rapid development of the regional economy, the problem of environmental pollution has become more and more serious, preventing environmental pollution, protecting the environment, and maintaining ecological balance has become an important measure of social development, and it is also the obligation of every citizen. The following is the report from the field investigation:

The pollution sources that cause environmental pollution are: 1. The feces discharged from public toilets emit an unpleasant smell and make people nauseous. 2. The wastewater discharged from the factory is black and smelly, and there are some filth floating in it.

3. The exhaust gas emitted from the factory is very pungent and will be emitted to all corners of the town. 4. The gas discharged from the fertilizer plant contains dust, lead, coal ash and other substances harmful to the human body. 5. There are often garbage discarded by visitors on the lawn of the park, which is not only unhygienic but also affects the city's appearance.

The pollutants that cause environmental pollution are: waste water, exhaust gas, feces, rotten meat, plastic bags, wooden chopsticks, garbage, etc.

Pollutants are very harmful to the environment and living things: they make the air turbid and have great harm to people's lungs; Poor disposal of domestic garbage will breed bacteria and seriously affect people's health; Sewage will affect domestic water and directly harm the human body.

After reading so much, are you a little worried about the current environment? Yes, the environment is closely related to our lives, and the protection of environmental sanitation starts from me, from now on: no spitting; No littering; Refuse to use disposable wooden chopsticks; Waste batteries and plastic bags should be disposed of; Plant more trees and do not trample on the lawn; Does not pollute water sources.

It is our duty to protect the environment!

5000 words?! It's up to you to figure it out.

For a moment, I burst into tears.

There are many kinds of tears. Tears of sorrow, tears of love, tears of gratitude......On the eve of Children's Day, I would like to share with you the tears I shed on Children's Day last year.

Last year's summer seemed to come very early, and the first day of June arrived with a stuffy atmosphere, unless you stay in an air-conditioned room, you will sweat a TV watch, this is not--

Mom, it's too hot, I'm going to buy some ice cream and come back! I said loudly to my mother while wiping the beads of sweat from my head.

Oh, be careful on the road! Mom replied unhurriedly.

I grabbed the key, stepped on my bike, and rushed to the supermarket, rushing straight to the cold drink cabinet, carrying a large handful of "cute" and "green mood". After paying, before I walked out of the supermarket, I felt that the temperature plummeted, as if it had fallen from midsummer to severe winter, and I heard a commotion outside. Broken!

I have a kind of foreboding, people say "June day, children's face, say change", I didn't expect to catch up on the first day of June! This is good, not only did my cold drink soak in the soup, but the new clothes on my body must have been soaked ......I wonder how my mother will scold me? Alas, it seems that this rain will not stop for a while and a half, and now I can only eat as much as I can, eat more and earn one!

I sat under the rain curtain in front of the supermarket and dried up a few ice creams one bite at a time.

Suddenly, a striking red umbrella appeared in the distance, isn't that my umbrella? Did my mother pick me up? No, it's so far!

Leave it alone, there are more of the same umbrellas! After a while, the umbrella was getting closer and closer, but the face was still not clear, and the umbrella had a clear goal - the supermarket! Closer, closer, the man with the umbrella, I finally saw clearly, it was really my respectable mother!

Mom was wearing a white shirt, her hair was messy from the rain, and she was like the usual neat mother, the only thing she had in common was that she still had a sweet smile on her face: "Go home......”

How she came, I don't know, why she came, I don't know. What I knew was that tears blurred my eyes, and my mother in the pouring rain blurred; The cold drink that was left in his hand was blurred; The supermarket in front of me couldn't see the ...... clearly

I can't remember exactly how I went back that day, but my mother's deep love for me and the bridge of love, the red umbrella, will always be engraved in my heart!

Deeply touched by the heart.

Moved, it seems, is only in an instant. However, in that moment, it can make me remember deeply, make me have endless aftertaste, and make me cry like rain!

During those days, my heart was darkened and I couldn't seem to pull it together. My grandfather died, my grandfather, who loved me the most, died, his tears had dried up, his eyes were no longer as clear as before, and he was staring at a certain place all day long.

The grades plummeted, and the teacher could only sigh frequently. I don't know what day I started, but I found a few more sheets of paper in my schoolbag that were stapled together with a stapler, on which the key points of the teachers of each subject were written. Beautiful and clean handwriting, who wrote it?

And why would he or she help me take an extra note?

I never looked, I threw it aside every time, and continued to think about my grandfather in a daze.

The paper was piled higher and higher, and it was already a thick pile. What kind of person is it that has such time and perseverance? This mystery, which I had been puzzled about, was finally solved by me after a gym class.

After the physical education class ended that day, I walked back to the classroom with heavy steps, and as soon as I walked into the classroom, I accidentally saw a person in my place, who was that person? I saw that person slowly turning around, and he and I were shocked, it turned out to be him, who had been fighting against me in his studies! I immediately stepped forward and glared at him

What are you doing? Are you sympathizing with me, pity me? Remember, no matter how far I fall, I don't want your charity!

With that, I took out a few pieces of paper from my bag that he had just stuffed into and tore them off in style. In an instant, the entire classroom fell silent.

He didn't say a word, silently returned to his position, buried his head and began to write hard, and after a while, a note flew over, I opened it, and it was so beautiful and clean handwriting: Grandpa will not be happy to see you like this in heaven. Cheer up, no one is competing with me for the first place, I'm not used to it!

After reading it, I felt very uncomfortable, I had a complicated feeling, tears rolled in my eyes, and I couldn't bear it to let it fall. I walked up to him again and yelled at him, "You don't have to worry about my business!

If you don't get used to it, you won't get used to it, and it won't get in my way! Why are you tired of being the first one? You don't have to show off in front of me!

Throwing off the last word, I turned around again and returned to my seat. He kept his head down and didn't say a word.

The next day, I thought there would be no more notes, but unexpectedly, there were two more, yesterday and today. In an instant, tears splashed, and I suddenly woke up to ......

Before this, I was cold to everyone, but he melted my cold heart ......Since then, I have been sunny and happy, and I am optimistic about life!

What is moving? A kind smile? A loving aid? Or is it a sacrifice that will not hesitate?

The concept of emotion is too broad and too broad: as small as a concerned look, as big as a sacrifice of life. Sometimes, a ray of early morning sunshine, a gentle birdsong, or even a busy ant can move people.

Touched by the bottom of people's hearts, the slight waves and ripples will make people's hearts flutter. Actually, I'm a girl who can be easily moved. A trusting look, a word of encouragement, and a casual touch will move me.

After a night of struggle, a ray of morning sunshine often brings tears down my eyes. When I meet friends after a long absence, a cup of light tea often makes me feel a lot of emotion in my heart: isn't that faint fragrance just like the smile and care given to me by my friends--- refreshing and endless.

Touching is omnipotent, she can melt the frozen heart and heal the broken heart. I remember reading a science fiction book about a girl who had special abilities since she was a child, but she never used them because the price of her use was her life. Until one time, the girl used a special function to save her brother and awakened the brother of the sealed soul.

Her special function is to find a small gap in the closed part of the person's soul, invade the person's heart, stimulate all her good memories, make the small pieces of her heart begin to melt, and thus awaken the closed soul. It is true that the story is fictional, however, I firmly believe that the heart that saves souls is sincere.

Moved everywhere, moved by infinite power, moved to inspire people to forge ahead! With a moment of gratitude, you will find that life is touching everywhere, and the world is so beautiful!

Interesting Science Exhibition 450 words.

During the summer vacation, the teacher took us to the gymnasium for an interesting science exhibition.

Walking into the gymnasium, I saw a lot of strange sights. Hey, what is that, a faucet keeps flowing water, but it doesn't give it a joint to the water pipe. When I saw the introduction, I realized that there was a transparent water pipe hidden in the water.

Yes! It turns out that the water pipe is the water in the faucet, which is called "sourceless water". My favorite is "Mirage".

I stood a meter away, looking ahead, there was a spring hanging in the air, I curiously stretched out my hand to touch it, but I couldn't touch anything, it was a "mirage"!

Then I saw a very large screen. There are many peculiar patterns on it, the most striking is a big head with two people, and it is written below that this one has 9 faces, and it is said that all of them have an IQ of 180. I was curious about the area, and many teachers also came.

Alas, I only found three faces, and our Chinese teacher, Mr. Ma, was pointing behind my back, and after a while, I found 9 long faces, which is really worthy of being a teacher!

There are a lot of fun and interesting things, I stopped all the way, talked and laughed, and watched my classmates touch the big microphone with their hands to "rush to the crown"; Listen to the students playing the electronic piano "Doremi"; Feeling the laughter of my classmates, I really gained a lot.

I reluctantly left, and I think that the progress of science is really fast, and I am more and more fascinated. It also lets us know that there are some things that we can't be too superstitious about, and we must believe in science, which can lead us to explore many unknown secrets.

I think this popular science exhibition is very meaningful.
