Let's sit in a circle first. Jia Jia gave us a handkerchief, so we asked Jaga to throw it away first.
The game has begun. Although everyone clapped their hands and sang the song "The Lost Handkerchief", I dare not relax at all. My heart was pounding, and I thought, don't leave it behind me ... but Jiajia just left the handkerchief behind me. After I found it, I quickly grabbed my handkerchief and jumped up, catching up quickly, but I didn't catch up at last. Then it was my turn to lose.
As I walked, I thought: I have to find a slower target. So, I quietly went around behind Yang Yang, gently put down my handkerchief and ran as fast as I could. As I expected, when I finished a lap and then ran to her position, she only ran half a lap. In this way, we chase and play in a tense and relaxed atmosphere.
Happy time is always so short, and it feels dark after not playing for long. We all reluctantly left the park and went home.
2. How to write a complete handkerchief?
Today, Mr. Feng gave us a special composition class. This time, Mr. Feng did not bring Chinese books into the classroom as usual, but brought many scientific tools. Is Mr. Feng going to give us a lesson?
I saw Mr. Feng put the iron shelf, plates, beakers, a box of matches, handkerchiefs and other scientific appliances on the podium. Then he picked up his handkerchief and asked us, "What is this?" We replied with one voice, "Handkerchiefs!" Teacher Feng said, "Yes, today we are going to do an experiment. The topic is" Unfired Handkerchiefs ". Because this handkerchief is insured by the insurance company, no matter how it is burned, it will not burn out. If it burns out, the insurance company will lose money! " "Impossible ..." The students began to talk about it. I think: handkerchiefs are like silk. If they touch or burn immediately, I think this handkerchief will suffer.
The experiment began, and we all stared at Mr. Feng's every move. She first soaked the handkerchief in a beaker full of alcohol, then put it on a plate and poured a little alcohol. So, Mr. Feng picked up a match and struck it with a bang. A flame immediately appeared on the plate. I thought to myself, the handkerchief must have burned out with such a big fire. Alas, poor handkerchief! After a while, Mr. Feng took out a towel soaked in water and covered it on the flame. The fire went out. What happened to the child's handkerchief? It must be a lot less. Teacher Feng lifted the handkerchief with tweezers. Wow, intact. It was completely out of my expectation.
Teacher Feng said, "It's interesting that I said I was insured by an insurance company. Actually, it is scientific to do this experiment. As we all know, when alcohol burns, the temperature above is high and the temperature below is low. The teacher uses 70% alcohol, which is volatile and helpful. When a handkerchief soaked in alcohol burns, it burns alcohol, but a handkerchief soaked in 30% water can't burn. Of course, if this 30% water is boiled, the handkerchief will also burn. " After listening to Teacher Feng's words, I suddenly realized that this little experiment still contains scientific principles. I must study science and build the motherland in the future!
3. I miss the old handkerchief composition 600 words "I have a cold, it's really uncomfortable!" Oh, I'm out of tissues. I want to roll a roll. "
"The table is dirty. Who will donate some paper towels to wipe? " At this moment, I was taking a tissue that I had just wiped my mouth and preparing to throw it away. Looking at the white paper towel in my hand, I don't know from which corner of my body, I feel a kind of inexplicable sadness. Nowadays, blowing your nose, wiping the table, wiping your mouth ... Many daily lives are inseparable from paper towels, which have become a necessity.
Indeed, paper towels are very convenient. Take it out when you use it, and throw it away when you are finished. Now everyone knows the word "tissue", but they don't know what a handkerchief is.
Handkerchiefs are gradually being replaced by paper towels. Miss handkerchiefs, I miss the softness of handkerchiefs.
You may argue that paper towels are softer than handkerchiefs nowadays, but they are different in texture-handkerchiefs are made of thread, while paper towels are made of pulp. What is pulp? It comes from wood pulp, where wood pulp comes from, where wood comes from, where wood comes from, and forests. I knew this for a long time, and the result made me very sad.
How much wood will I waste with a paper towel that I use alone every day? How much wood will be wasted in a class? More than 65.438+300 million people in China will …, although I don't know if anyone has done this statistic, it can be concluded that it must be very shocking. There are too many things that waste wood in the world. Why waste it? Maybe waste paper can be recycled, but it will definitely be lost halfway. In addition, other energy sources will definitely be used to produce paper towels. Isn't this a waste? From a humanitarian point of view, it takes many years for a tree to grow into a talent, and it is cut down as soon as it becomes a talent or even before it becomes a talent. What a pity!
I miss handkerchiefs and the fun they bring. I remember once upon a time, several of our partners played the game of "throwing handkerchiefs" together. Now we can only search for that childlike interest in our memory.
Well, I could have relived my memory, but it's not easy to find a handkerchief now. I miss handkerchiefs. I miss all kinds of handkerchiefs.
For convenience, paper towels replaced handkerchiefs. We are ahead of natural resources, or we have overdrawn natural resources. I wonder how long the earth can support mankind. .

5. How to write the composition of apples There are many fruits I like, such as watery lychees and oranges in Huang Chengcheng ... Among them, I like eating red apples best.
The shape of an apple is round, with holes recessed from top to bottom, which looks like a balloon. Apple skin is slippery. If you wash the apple, it will "run away" and accidentally play hide-and-seek with you.
The color of the apple is red, with two white spots on it, which is a sign of apple maturity. It looks like my brother's little red face and a shy little girl, so you can't help biting.
The taste of apples is from My Sweetie, crisp and raw, which makes people want to eat. It is really "sweet in the mouth and sweet in the heart". Apple's flesh is watery and tastes sweet and fragrant. Take a bite, delicate and soft, refreshing.
Every autumn, apples will be covered with branches, and the naughty tree mother will bend her waist. Apples are crystal clear and juicy. If you put them in the refrigerator for a while, they will become more refreshing and delicious.
Therefore, I like apple very much, and I like its lovely appearance.
6. How to write "Lose the handkerchief, lose the handkerchief ……" Every time I hear this nursery rhyme, I will think of the scene of losing my handkerchief with my classmates after school. It was a Thursday afternoon after school, and we rushed to the playground like the tide to prepare for the game of losing handkerchiefs. The game started, and my chest kept jumping like a kangaroo. After Wang Yu walked around with a handkerchief, I suddenly found that the handkerchief in her hand was gone. We all looked back in unison. At this moment, Takumi Inui found a handkerchief behind him, so he grabbed it and chased it out. However, it was already late, and Wang Yu, the "Scud", had already run behind Takumi Inui. According to the rules, Takumi Inui will give a performance. However, Takumi Inui can neither tell stories nor dance, so he can only croak like a frog. The students laughed at this. The game continues. The children clapped their hands and sang the song The Lost Handkerchief. I found Takumi Inui smiling mysteriously. I thought, "She won't leave her handkerchief behind me!" " I quickly looked behind me. Sure enough, the handkerchief was behind me. I grabbed my handkerchief and ran. Who was left behind? I walked behind Wang Yu and thought, "Her feet are too long. What can I do if I catch up with her? " ? Yes, I left it behind ... "I secretly laughed and left my handkerchief behind Lin. I ran for half a lap before he found that when he picked up his handkerchief and chased me slowly, I was already in his seat ... The sun set and our game ended in cheerful laughter.
7. How to write an explanation for the ingredients of apples? Rosaceae; Apples are propagated and cultivated by grafting.
There are two kinds of rootstocks: arbor rootstocks and dwarf rootstocks. Commonly used tree rootstocks are Juglans mandshurica, Haitang Xifu and Vitex negundo, and dwarf rootstocks are mainly imported from Britain.
Wide rows and close planting are adopted, and the behavior is north-south. The soil in southern China is planted before freezing in autumn and winter, and in northern China it is planted during thawing in spring.
Apple is weak in self-fruiting, so pollination trees must be arranged when planting. Resource distribution: native to Southeast Europe, Asia Minor and South Caucasus.
1870 was introduced to Yantai, China, and has been widely cultivated in the southeast of Northeast China, North China and Northwest China in recent years. Garden use, flowering period for viewing; In the fruit-bearing season, fruits are numerous, colorful and attractive.
Apple originated in Europe, Central Asia, West Asia and Turkey, and was introduced to China in19th century. "An apple a day" is a well-known health slogan.
Indeed, apples are rich in sugars, organic acids, cellulose, vitamins, minerals, polyphenols and flavonoids, and are called "all-round healthy fruits" by scientists. So, what health care function makes it win such a good reputation? Hypolipidemic: The human experiment of Japan Fruit Research Institute showed that after eating two apples a day, the triglyceride level in subjects' blood decreased by 265,438+0% after three weeks, and the high triglyceride level was the chief culprit of arteriosclerosis.
After apple pectin enters the human body, it can combine with bile acids, absorb excess cholesterol and triglycerides like a sponge, and then excrete it. At the same time, the acetic acid decomposed by apple is beneficial to the catabolism of these two substances.
In addition, vitamins, fructose and magnesium in apples can also reduce their content. Lowering blood pressure: Excessive sodium is an important factor causing hypertension and stroke.
Apples contain enough potassium, which can be combined with excess sodium in the body and excreted, thus lowering blood pressure. At the same time, potassium ion can effectively protect blood vessels and reduce the incidence of hypertension and stroke.
Dr Susan Arlich, a famous British pharmacologist, found that polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases. Prevention of cancer: A study by Hirosaki University in Japan confirmed that polyphenols in apples can inhibit the proliferation of cancer cells.
A study in Finland is even more exciting: flavonoids contained in apples are an efficient antioxidant, not only the best vascular cleaner, but also the bane of cancer. If people eat more apples, the risk of lung cancer can be reduced by 46%, and the risk of other cancers can also be reduced by 20%.
The latest research by the French National Institute of Health Medicine also tells us that proanthocyanidins in apples can prevent colon cancer. Antioxidant effect: The research team of Cornell University in the United States soaked the brain cells of mice in a liquid containing quercetin and vitamin C, and found that the antioxidant capacity of brain cells was significantly enhanced.
Compared with other fruits and vegetables, quercetin in apples is the best, and red apples are better than yellow apples and green apples. Therefore, apples are the best food for patients with Alzheimer's disease and Parkinson's disease.
Strengthening bones: apples contain mineral elements boron and manganese that can strengthen bones. A study in the United States found that boron can greatly increase the concentration of estrogen and other compounds in the blood, which can effectively prevent calcium loss.
Medical experts believe that if menopausal women can consume 3 grams of boron every day, their calcium loss rate can be reduced by 46%, and menopausal women eat more apples, which is beneficial to the absorption and utilization of calcium and the prevention and treatment of osteoporosis. Maintain acid-base balance: 70% of diseases occur in people with acidic constitution, and apples are alkaline foods. Eating apples can quickly neutralize excessive acidic substances in the body (including acid produced by exercise and acidic metabolites produced by acidic foods such as fish, meat and eggs), and enhance physical strength and disease resistance.
Lose weight: apples will increase satiety, and eating before meals can reduce food intake and achieve the purpose of losing weight. As for whether to peel the apple, people have different opinions. Without peeling, it is possible to eat pesticide peeling. The most nutritious part of apple is the skin, and most of the fiber is also on the skin.
There are many kinds of fruits, such as crystal clear grapes, big and sweet watermelons, sour and sweet pineapples and delicious and beautiful peaches, but I only like apples. Just like a magician. Look, he has learned to change his face. There are red and green! Well, having said that, have you ever eaten an apple? It's like a musician! Have you ever heard its sound?

"You smell, there will be a faint fragrance naughty into your nostrils. Taste it, the immature one is sour and astringent, which seems to remind you that you can't eat it. When cooked, it is sour, sweet and delicious, and you will want to eat it. This bad apple is sour and bitter. Does it look like a taster to you? Touch its skin with your hands, some are smooth, like a baby's skin, and some are rough, like the face of a weather-beaten grandfather. Usually it is dry, but if it is washed with water, it will naturally become a "soaked chicken." You see, this ordinary apple has so many advantages! Now let's introduce its functions!
