作文 篇1

厨房里的一袋土豆发芽了，妈妈准备扔掉，可我觉得很有趣，准备把发芽的土豆种到花盆里。

A bag of potatoes in the kitchen sprouted, and my mother was going to throw it away, but I thought it was very interesting, and I was going to plant the sprouted potatoes in the flowerpot.

我回想着爷爷种土豆的方法，先把泥土翻松，接着挖了一个洞，把土豆放到洞里，然后把泥土盖上，把土豆的芽露出地面，最后还浇了一些水，土豆就这样种好了。

I recalled my grandfather's method of growing potatoes. First, I loosened the soil, then dug a hole, put the potatoes in the hole, covered the soil, exposed the potato buds to the ground, and finally watered some water, so the potatoes were planted.

我经常给这盆土豆浇水。过了几天，我惊喜地发现土豆慢慢长出了小小的两片叶子。土豆一天天长大，由于放在阳台上没有太多的阳光照射，土豆的茎长得又细又长，而且没有一片绿色的叶子。妈妈说这样的土豆是没有营养的，长不出小土豆。可我不甘心，还是照常给它浇水，希望她快快长出小土豆。

I often water this pot of potatoes. A few days later, I was pleasantly surprised to find that the potato slowly grew into two small leaves. Potatoes grow up day by day. Because there is not much sunlight on the balcony, the stems of potatoes grow thin and long, and there is no green leaf. Mother said that such potatoes are not nutritious and can not grow into small potatoes. But I was not reconciled, so I still watered it as usual, hoping that she would grow small potatoes soon.

过了一个多月，我发现土豆芽越长越黄了，我以为它已经枯萎了，就把土豆一下子拔掉了，可没想到竟然挖出了一个小小的土豆。我惊喜极了，心想：不止是一个吧！我再挖又挖出了一个，比刚才又大了一点。

After more than a month, I found that the potato sprout was growing and yellowing. I thought it had withered, so I pulled out the potato at once, but unexpectedly a small potato was dug out. I was so surprised that I thought: more than one! I dug another one, which was a little bigger than before.

我高兴地拿着两个小土豆跑到妈妈面前，大声欢呼：“妈妈，瞧，这是我的劳动果实！”妈妈也为我高兴。

I happily ran to my mother with two small potatoes and shouted: "Mom, look, this is the fruit of my labor!" Mom is happy for me, too.

这是我第一次种出的两个小土豆，我感到很自豪。

This is the first time I planted two small potatoes, and I am very proud.

写观察日记 篇2

8月19日星期六晴

Saturday, August 19, sunny

那一天早上，一只大大的蜗牛爬到了我的花坛上，于是我带着好奇心去观察这只大大的蜗牛。

That morning, a big snail climbed onto my flower bed, so I went to observe the big snail with curiosity.

它长着一个大壳，身体上好像背着一个“房子”似的。它的身体软绵绵的，比海绵还柔软。头上长着两只眼睛，两只触角。

It has a big shell and seems to have a "house" on its back. Its body is soft, softer than a sponge. He has two eyes and two antennae on his head.

我接着观察的时候，发现那只大大的蜗牛竟然睡着了，于是我把那只蜗牛拿了起来。我在心里想：该怎样把蜗牛叫醒呢？我绞尽脑汁，苦思冥想，终于想到了科学老师说过，蜗牛正在睡觉的时候，如果你把它放进水里，那只蜗牛就会把头伸出来，找一样可以立体的东西爬上水面。

When I continued to observe, I found that the big snail had fallen asleep, so I picked up the snail. I thought to myself: How can I wake up the snail? I racked my brains and thought hard. Finally, it occurred to me that the science teacher said that if you put the snail into the water when it was sleeping, the snail would stick its head out and find something that could be three-dimensional and climb up to the water.

于是，我试着把那只蜗牛放进水里面。果然，那一只蜗牛把头伸了出来，我立刻把那只蜗牛拿出来，生怕它被淹死。

So I tried to put the snail into the water. Sure enough, the snail stuck its head out, and I took the snail out immediately, for fear that it would drown.

突然，那只蜗牛吃我的手指，仿佛对我说：“我的肚子好饿！”于是我把蜗牛放到菜叶旁边。

Suddenly, the snail ate my finger, as if to say to me: "My stomach is so hungry!" So I put the snail next to the vegetable leaves.

过了一会儿，那只蜗牛拉出了一些白色的珠子。我想：为什么蜗牛会拉出白色的珠子呢？我立刻去看《十万个为什么》，里面说到：蜗牛拉珠子就是正在生宝宝。

After a while, the snail pulled out some white beads. I thought: Why do snails pull out white beads? I immediately went to see "One Hundred Thousand Whys", which said that the snail pulling the bead was giving birth to a baby.

过了几个星期，那几只小蜗牛出生了，但同时，那一只大蜗牛，也就去世了。

A few weeks later, the little snails were born, but at the same time, the big one died.

多么可爱的蜗牛啊！

What a lovely snail!

写观察日记 篇3

今天，李老师给我们布置了一个小任务，写观察日记。

Today, Miss Li assigned us a small task to write an observation diary.

首先，我拿出绿豆、纸巾、纸杯这些材料，我先把纸巾塞进被子里，拿着杯子去装些水，再把绿豆放进去等待它探出头来，可是过了半个小时！绿豆还是没有动静；我很生气！心里想着：“竟然无视我。真是大胆！”爸爸走过来说：“你太心急了，明天它就会探出头来的！”

First of all, I took out mung beans, paper towels, paper cups and other materials. First, I put the paper towels into the quilt, took the cup to fill some water, and then put the mung beans in to wait for them to stick their heads out, but after half an hour! The mung bean is still quiet; I'm angry! I thought, "How dare you ignore me!" Dad came up and said, "You are too anxious. Tomorrow it will stick its head out!"

第二天，放学回家，我飞奔到阳台发现豆芽长出来了，我好奇地摸了一下，“哟！有点硬”。长出来新的叶子，有一些是青绿色，有些是青紫色的，中间还空了一点儿呢！躲在绿色衣裳里，迟迟不肯出来，如一个“害羞的小女孩”一天天长大，一天天变老啊！

The next day, when I came home from school, I ran to the balcony and found that the bean sprouts had grown. New leaves grow, some are green, some are purple, and there is a little space in the middle! Hiding in green clothes and refusing to come out, you are like a "shy little girl" growing up and getting old day by day!

两天后，发现有一颗绿豆已经变高了，大约有五六米了，其他的只有三四厘米，差别真大。茎很细，毛有点粗糙的感觉。还有四五根绿豆弯弯的、低着头，像挨了训一样。叶子有点儿皱儿，给我点不太新的鲜的感觉，但是却好香啊！

Two days later, I found that one green bean had become taller, about five or six meters, and the others were only three or four centimeters. The difference was really big. The stem is very thin, and the hair is a little rough. There are also four or five mung beans bending and lowering their heads, as if they had been trained. The leaves are a little wrinkled, giving me a little fresh feeling, but they are so fragrant!

第五天，绿豆变得更高了，比前天高了两三厘米，香味扑鼻而来。叶子绿绿的，似乎变得新鲜点儿。

On the fifth day, the mung beans became taller, two or three centimeters higher than the day before, and the smell came. The leaves are green and seem to be fresh.

啊！大自然的植物真是神奇！

Ah! The plants in nature are amazing!
