In study, work and even life, everyone has come into contact with composition. Composition is the transition from internal language to external language, that is, from compressed and concise language that one can understand to developed language with standardized grammatical structure.

Transformation into external language forms that can be understood by others.

So, how to write an essay?

Below is a 400-word essay on potatoes that I compiled. You are welcome to share it.

Potato Essay 400 words 1 On Sunday, we went to grandma’s house to help plant potatoes.

As soon as I entered grandma's house, I saw many big fat babies-potatoes lying on the kang, covered with small sprouts like bamboo shoots. I asked strangely: "Grandma, these potatoes have sprouted, why haven't they sprouted yet?"

"Eat it?" Grandma said with a smile, "Silly boy, you know how to grow it." "Plant it?" I nodded in understanding and said to myself, "Plant it on potatoes."

How to grow potatoes?” After lunch, I finally started to plant potatoes. I saw my grandma and mother holding the potatoes with sprouts in their left hands, holding a knife in their right hand and carving a circle of deep cuts around the sprouts.

I grabbed the sprouts with my hands and twisted them, and a potato piece with sprouts was dug out. It was really interesting. I wanted to try it, but they said it was too dangerous to hold a knife and that my job was to grow potatoes.

In the afternoon, my parents, grandparents, and I went to the fields to plant potatoes.

Grandpa first dug out ditches in the ground with a small pickaxe. Dad was responsible for pouring water into the ditches. When the soil in the ditch became like mud, my mother and I would plant potato pieces with sprouts into the mud.

This is a technical job, which not only requires the buds to face upward, but also the distance between the two trees must be just right, neither too far nor too close.

I worked very hard, and the more I worked, the better I became. It didn’t take long for the potatoes to be planted.

Through this labor, I understand the hard work of farmer uncles in farming and how hard-earned food is. I will never waste food again in the future.

Potato Essay 400 words 2 After the beginning of spring, the earth is getting warmer.

Today is sunny and breezy, a great day for planting potatoes.

The backyard of my grandpa’s house is an independent vegetable garden, and we plan to plant a patch of potatoes.

Grandpa is weeding and loosening the soil with a hoe.

I help my grandma choose seeds.

Grandma told me that potato seeds should be chosen with round heads and thicker buds.

Looking at the hundreds of potato seeds, I felt a little dizzy.

How many to choose?

It’s a waste of time to pick too much, and you have to run up and pick again if you pick too little.

I thought about it for a moment, hey, I have it.

I ran to the backyard and saw that my grandpa was already digging a hole: "Grandpa, how long is this plot?" Grandpa said with a smile: "Let's measure it with a hoe handle. A hoe handle is about 1.8 meters." We.

Put the hoe handle on the ground, one hoe, and then another, about three and a half. I silently calculated that the length of this hoe was about 6.3 meters.

The width is about 1.5 meters.

Grandpa also told me that the distance between pits is about one and a half inches, about 25 centimeters.

My mind was spinning rapidly. Ha, it happened to be the tree planting problem we learned in fifth grade.

This is a "don't lose at both ends" type.

The pits that can be dug on the long side: 630÷25≈25-1=24 (pieces), the pits that can be dug on the wide side: 150÷25-1=5 (pieces) Then, the total number of pits to be dug is: 24×5

=120 (pieces) I ran upstairs and told my grandma that we needed to pick 120 potato seeds.

With data support, we selected the species in less than half an hour.

My grandparents always praised me for being smart, and asked me to do calculations in advance next time I went to plant potatoes in a field a thousand meters away.

This way grandma doesn’t have to go all the way to pick too many potatoes to plant in the field, nor does she have to run back home to get them because she doesn’t have enough potatoes.

Using the "tree planting problem" to grow potatoes is really getting twice the result with half the effort!

Potatoes Essay 400 Words 3 The teacher walked into the classroom with many potatoes in his arms, and the class immediately exploded, "Teacher, are you going to give us French fries?" "Are you going to eat the potatoes raw?" The students were all talking about it, and the teacher

He smiled and said, "Give you a straw and use it to penetrate the potatoes!" When the students heard this, they kept saying that the teacher was lying to us.

Although everyone didn't believe that the straw could penetrate the potatoes, they still tried it.

We are like a bunch of headless flies, mindlessly poking around with straws, but we can't pierce them.

There was really no other way, so we asked Teacher Cheng to demonstrate for us.

I saw him pressing the end of the straw with his thumb and quickly piercing the potato. Unexpectedly, the thick potato was pierced, with some mashed potatoes mixed with it.

The students were stunned. They picked up their straws and potatoes and pricked the potatoes again according to the teacher's method.

Unexpectedly, this time, the potato was actually pierced.

Why can soft straws pierce thick potatoes?

It turns out that it relies on the effect of atmospheric pressure.

When your thumb touches the mouth of the straw, the air is trapped inside, and when you quickly stab the potato, the straw becomes hard, so it penetrates the potato.

This experiment is really interesting.
