2. Composition on Yam 1 10 Digging yam may sound simple, but the fact is one word: difficult? But I had such an experience once. Why don't you listen to me?

A few days ago, our good friends Xiaoxiao's family were going for a ride in the suburbs. Xiaoxiao asked several of our good friends to go together. Along the way, we talked and laughed and had a good time. Ten minutes later, we arrived at the so-called yam base. As soon as we got off the bus, we rushed over. Huh? Is this a yam base? What a big pit. After asking, I realized that these big pits are all traces of people digging yam, and these yams have all been dug. Hearing this, we were very depressed and thought, "This time it must be for nothing, but …" This is the uncle who dug yam. "We still have a small piece of land left there, so we can dig it with tools." Hearing this, we jumped three feet high happily, grabbed our tools and ran to the field. composition

When we got there, we saw two boys digging yam. There are many yams piled up next to them. We will learn from them how to dig. They stopped working and told us that this land is sand. You need to sweep it by hand, and you can see the yam roots with thick fingers. Then you can dig along the roots, and you can dig.

After listening to the boy's words, we got busy: we were all digging up the soil and looking for roots. Everyone is so busy that it doesn't look like a rest at all. But just then, a partner shouted, "I quit." How can you dig? " Why is it always bad? Let's go and play something else. "When she finished, everyone responded easily and put down their tools to play something else. But I think we must dig yam to show them. At this moment, my good friend Mix said, "You'd better stop digging. Look at those two boys sweating. You can't dig yam. "I said to her," Before you decide whether you can do it, you must try something. You can play if you want. I want to dig here. " After I finished, he shook his head and left. I found a long, thick yam root and began to dig it up. At this time, I only heard a "click" and the yam broke. The boy next to him said, "You have to dig next to the yam root and get closer. Because yam grows vertically in the soil, if you dig up and down, it will definitely break. "After listening to his words, I picked another yam root and dug it around. Digging for nearly 20 centimeters, I found that I was a little depressed before I dug to the end, but then I thought: this shows that the yam I chose is good. So he dug up again with great interest. Half an hour passed. I looked up and saw a big, thick and long yam at my feet. I'm so happy. When I was about to pick it up and meet my friends, the big brother next to me said, "It's not easy for you to dig for so long. Let me give you two. "As he spoke, he sent me two yams he dug, and I happily said thank you to him. composition

In the evening, my mother fried a plate of yam and cooked porridge with yam. I think the yam in my mouth is so sweet, waxy and soft, because I dug it myself?

4. Write an article about iron stick yam with the word 100. Your first blossom is dead, but I'm still waiting for you and me to "blossom".

It was a beautiful afternoon, watching the friends playing happily outside the window and watching the disastrous results of the final exam. Somehow, a kind of sadness rushed from the body to the eyes at once. I want to shout, because no one understands; I want to cry because I have no sympathy. The once proud and self-respecting heart has vanished. I sank into the sea like that stone, except for a ripple, and then it was as silent as death.

"Let's go around the street!" The Spring Festival is coming, and the lively atmosphere has temporarily eased my sadness. Unconsciously, I came to the flower and bird market. Being in it is like being in a virgin forest. Suddenly, a strong fragrance came to the nose. I turned around and met you.

"Boss, what is this flower? How can it smell so sweet? " I gently picked you up and saw that the water bottle was covered with long stems and whiskers. There were two stamens at the bottleneck, and one of them was in full bloom, which was very touching. "Oh, you take this bottle called hyacinthus orientalis. Although small, its origin is not simple: it takes several years to hone from a seed to root and sprout. After that, two stamens were produced. The first one didn't last long, and the fragrance was very strong. The other one had to wait for a year in the ground to open, and the fragrance was even stronger. After that, hyacinthus orientalis completed the task and slowly withered. " The boss told me poetically.

I look at you in disbelief, small but full of energy. What can keep you in obscurity for years, just for the magnificent bloom of two volcanic eruptions? When the flowers bloom, you spend your whole life blooming amazing and fragrant flowers, but you die because of it. Isn't the true meaning of life the same? Instead of living an ordinary life, it is better to accumulate strength from now on and work hard for the only "bloom"! Thank you, hyacinthus orientalis. This wonderful meeting helped me out of the shadows.

I will take you home and take good care of you. Your first bud has been "fragrant", and I'm still waiting, waiting for you and me to "bloom" in hyacinthus orientalis. It's nice to meet you beautifully!

I made a 400-word composition for the first time. Last summer vacation, my mother and I went to Shan Zhi to plant a yam, hoping it could grow in nature. At first, I went to see it almost every day, and watered the yam from time to time, hoping that it would grow some yam for us to eat.

I haven't seen yam for a long time recently. But I still remember that my yam was buried by the sand washed down from the mountain by Typhoon Fete, but I still found it. Typhoon "Fete" was one of the biggest natural disasters in Cixi last year, which also triggered the debris flow in Liyou Mountain. To my surprise, my yam was still alive after it was found.

Today, I decided to go to Shan Zhi to see Chinese yam. I finally climbed the mountain and couldn't wait to see the yam. However, when I found a place where I could grow yam, I couldn't find it. But my mother doesn't think yam is dead. In a few years, that place will be full of yam.

At this time, you can come out. Ha, don't worry, it's very hot. You should cool it for a while, then pick up a paragraph and swallow it in one gulp. A faint "fragrance" and "sweetness" will come to my face, a bit like eating sweet potatoes, but if you taste them carefully, you will find that there is still a little "hemp" taste. After eating the first bite, I want to eat the second bite.

7. The specialty of my hometown is yam. Please write a 400-word composition around this sentence: "The river in my hometown, the river in my dream, your jubilant waves have nurtured the flowers in spring." Whenever I hear this song, I can't help thinking of the river in my hometown. Sometimes the river is sparkling and row upon row, sometimes it is as level as a mirror, sometimes fish leap out and splash a lot, and sometimes the petals of peach blossoms on the shore float into the river, just like a fairyland.

In spring, peach blossoms bloom on the shore. Yingchun opened her sleepy eyes and looked at the clear river. The children who just took off their winter clothes jumped and cheered and ran to the shore to see the beautiful peach blossoms in full bloom. The mandarin fish in the river were very fat. From time to time, they jump out of the water to meet the children on the shore! There are also some small fish playing in the crystal clear river, cheering the arrival of spring.

Time slipped away, the spring of March gradually left us, and the hot summer came. The river has become bluer. Fireball-like sunlight shines on the earth and rivers, and the rivers become warm. The fish in the water are bubbling in the water, and some small fish hide under the lotus leaves to resist the heat of the sun. At night, the temperature drops in the morning, and a cool breeze blows from time to time. People are talking to each other on the shore with chairs, and their laughter keeps rising and falling. The river rippled, as if listening to people on the shore, with beautiful smiling faces.

Unconsciously, it is cool autumn, and the flowers on the river bank are in full bloom, red as fire, pink as frost, yellow as gold and white as snow ... Flowers of different colors compete with each other and are reflected in the river, which is very beautiful. On the day I arrived in early autumn, the river became particularly blue and the sky was particularly clear. Compared with yesterday, the air immediately has the coolness of autumn. The children ran to the river to catch fish and touch shrimp, and they were very happy. Farewell to the coolness of autumn, the river in my hometown entered the solemnity of winter, the flowers on the shore also withered, and the river also bid farewell to people and entered a short sleep.

I love my hometown, and I love the river in my hometown even more.
