A year's plan lies in spring. " In this spring and March when flowers are in full bloom, it is the busiest season of the year, and schools are no exception. However, at the beginning of the semester, my grades were not satisfactory. This has caused a serious blow to my mood. So, I decided to play in the park.
Sighed, looked up at the treetops, new leaves have quietly appeared, and several birds are standing on the branches, singing carefree. "Oh, how relaxed this bird is. If only I were a happy bird." "Son, you can't understand the law of the jungle in nature." When I was talking to myself, a voice that had experienced the vicissitudes of time came into my ear, and I couldn't help looking inside.
An old man with gray hair was sitting in a wheelchair not far away, and I shivered. How like withered flowers in winter! Seeing that I turned my head, he continued, "naturally." If you are not strong enough, you will often starve to death or even be eaten by other animals. Therefore, if you don't want to be buried by the wind and sand of the times, you have to prove that you are strong enough and you are still young. "
Although I don't understand these principles, it calms my mood a little.
After returning home, I carefully analyzed and corrected the test paper, but I remembered the weather-beaten voice and vicissitudes of the old man I met in the park. It makes sense to think about it carefully. Yes, I am still young. Isn't this more precious than the spring of a year? Don't wait until you are white-haired. The plan of the year lies in spring, so we must work hard from now on.
In the math exam, I got the ideal result as I wished.
"Where is spring? Where is spring? " The children are singing cheerful songs. I know that we young people are like flowers in spring, and the future of our motherland is in our hands, so start working hard now!

On Sunday, I enjoyed my father's cactus at home. Suddenly found that cactus, cactus, cactus whip and other cactus plants have a common feature, that is, the stems are thick green, with many spikes on them.
I asked my father, "Why does cactus look like this?" Dad said: "Because the plants of the family Immortaceae originated in Latin America and gradually evolved and survived in the arid desert, their structures have strong drought-resistant characteristics." I look around and admire this special flower curiously. Why does cactus have no leaves, only thorns that sting people? Without leaves, how can it absorb and transport nutrients? How can you live so well?
Through careful observation and searching for relevant information, I finally discovered a secret. It turns out that the thorns on the cactus are changed by leaves. Because cactus lives in the desert for a long time, where it is hot and dry, if it grows big leaves, a lot of water will evaporate from the leaves. Therefore, the leaves of cactus become thorns, and the fleshy stems store sticky pulp, which can better absorb and maintain water in the body. Ah, the thorns on the cactus are leaves! I finally understand that cactus is thick and prickly, which is the result of adapting to the arid environment.
In addition, my father also told me that the large area of cactus thorns will not only reduce water loss, but also make other animals afraid to hurt it. I didn't believe it, so I touched the prickle of cactus with my hand. It really hurts! No wonder people dare not touch it.
Cactus is too clever. It knows how to change itself flexibly in order to survive.
A thorn is a leaf, and a leaf is a thorn. This is the secret of cactus I discovered. I believe that problems in life are everywhere. As long as you are good at observing, you will find more secrets.

What is happiness? Have I ever been happy in my life? Why can't I find a happy figure? I often think about these things because I think happiness is invisible in my life, and maybe there is no happiness at all.
Because getting up, brushing your teeth, eating and going to school are trivial things every day, you have to listen to teachers with heavy eyelids and growling stomachs at school, and sometimes you even feel dizzy, thinking that "the line segment between two points is the shortest" and "the surface between two points is the shortest". Or you have to accept the physical torture of teachers-heavy homework and daunting exams every day, mental torture, and you have to report to your mother if you fail the exam, but what you get is lion roars-like thunder, and life is worse than death.
Or listening to MP4 and playing games in my spare time, I have to be impressed by my parents' truth, so I have to lock up my interest and study and practice alone, feeling that life is so boring. But I suddenly found that life is not as boring and helpless as I thought. In fact, happiness is everywhere, it depends on whether you are willing to bend down to pick it up!
When you are at school, you can study with your classmates. If you want to, you are not alone, there are many classmates working with you, and you will find happiness.
When you trudge into the house after a hard day's study, your heart will be relaxed and you will find happiness with your mother's kind smile and eating the dishes cooked by your mother.
When you help people in need, you leave a fragrance on your hands.
Words of comfort when repeatedly frustrated.
I find that happiness is everywhere, but you need to pay attention to it with your heart, so that you will be full of happiness.

On Sunday afternoon, it was very sultry. I walked into the yard and fiddled with Grandpa's "precious flowers and plants". Suddenly, I saw a snail slowly climb up the leaves. "Are snails pests or beneficial insects?" "Why does it always leave a long line where it passes?" "Where are its nose and eyes?" A series of question marks came to my mind.
I ran into the room and asked my father who was reading the newspaper. Father smiled and said, "since you want to know the secret of snails, why don't you experiment yourself?" "Yes! Why didn't I think of that! " So I decided to try it myself.
Are snails pests or beneficial insects? I adopted the method of "testing turtles with various food products" to test snails. First, I found Chinese cabbage leaves, steamed bread and small mosquitoes, and then I caught some snails. I numbered them separately and put them in front of these foods. Probably they were all hungry and climbed to their favorite food, but every snail chose Chinese cabbage leaves and chewed them, but they didn't smell other food. Soon, the leaves of Chinese cabbage shit. Snails are a big pest. Then, I conducted a second experiment: "Why does a snail crawl and leave a long line?" I grabbed it high first, and when its head stuck out of its shell, I touched its big plate. Before my hand touched it, it shrank back again, thinking, this snail is really a "coward"! I did it several times, but it didn't work. I am really depressed. At this time, my father came over and said, "I am discouraged when things are not done. I want to be a scientist when I grow up!" " "I was so excited by what my father said, and I was excited again. Suddenly a way flashed through my mind. " Okay, okay. ""I'm dancing with joy. I carefully cracked the snail's shell with a sharp stone, pulled out the meat and touched its bottom with my hand. I saw that the sticky thing below was its foot, which was snail's excrement to help the snail crawl.
Finally, I want to see the snail's eyes. Where is its nose? I put a cabbage leaf in front of a snail, and the snail touched it with a pair of long tentacles, then touched it with another pair of short tentacles below, and then I swallowed it in one gulp. I think: maybe one pair is eyes and the other is nose. But which pair are eyes and which pair are noses? I took another leaf and another cabbage leaf about the same size and put it in front of another snail. Because the difference is not very big, snail's eyes are useless! I saw it touching with a small tentacle, and I knew which one was a cabbage leaf and which one was a leaf. Now, I have discovered another secret: the big tentacle has the function of eyes, and the small tentacle has the function of nose.
Through this series of experiments, it is really rewarding! I not only discovered the secret of snails, but also understood a truth: if you want to make inventions when you grow up, you must find problems from an early age and learn to solve them.
Hope to adopt, O(∩_∩)O Thank you.
