【日记】我学会了游泳观察日记400字：记录十天学游泳的变化

十天学游泳的观察日记怎么写：只挑三天详写，其余一笔带过

观察日记记录的是变化。十天学游泳，每天都有事发生，但并不是每天都值得写满一整段。想把这组日记写清楚，第一步反而是做减法：从十天里挑出三个最重要的日子，其余的日子用一句话带过。

第一个要详写的日子是第一天，任务是写怕水。别只写我害怕，要写怕水长什么样子：站在池边不敢把脚伸进水里，水刚过肩膀心就咚咚跳，手指死死扣着浮板，指节都发白了。观察日记的重点是观察，先把自己在池边的样子看清楚，再落到纸上。

第二个详写的日子是第五天，任务是写漂浮。这是十天里第一个真正的进步点。写漂浮要写身体的感觉：后背贴着水面，耳朵一半泡在水里，听见嗡嗡的声音，手一松，身子居然没有往下沉。把这种又轻又稳的感觉写出来，读者就能明白这一天为什么值得记。

第三个详写的日子是第十天，任务是写游出一段。这一段要写出距离感：蹬了六下腿，手一撑，指尖碰到了池壁。用数动作的办法量出距离，比写我游到了对岸更具体。结尾收一句当天的真实感受就够了，不用写坚持就是胜利之类的大道理。

剩下的七天怎么处理？挑一两天补一句过渡就行，比如第三天又呛了一口水，第七天敢独自扶板漂了。其余日子可以合并成一句：中间几天都在练换气，进步不快，但没有退步。

最后一个小技巧：每则日记开头写一句当天的天气或水温，比如今天太阳很大，水摸着不凉。观察日记观察日记，有了这些观察点，整组日记才像观察，而不是一堆普通日记凑在一起。

还有一点：三个详写的日子顺序不能乱。有人想把最精彩的第十天放在最前面，再回头写第一天。观察日记是按日期排的，第一天的怕，正是为了和第十天对照。顺序对了，读者才会在第十天真正替你高兴，也为第一天的你捏一把汗。

How to Write a Ten-Day Swimming Observation Diary: Detail Three Days, Summarize the Rest

An observation diary records change. Ten days of swimming lessons are full of events, but not every day deserves a full entry. The first step is subtraction: pick the three most important days and let the rest pass in one sentence.

The first day to write in detail is day one, and its task is fear. Do not just write that you were scared; write what fear looks like: standing at the pool edge without daring to put a foot in, heart pounding when the water reaches your shoulder, fingers gripping the kick board until they turn pale. Observation comes first; look closely at yourself by the pool, then put it on paper.

The second detailed day is day five, and its task is floating. This is the first real progress point. Describe the feeling of the body: your back resting on the water, one ear half submerged humming with sound, and when you let go, your body does not sink. Capture that light, steady feeling and readers will understand why this day matters.

The third detailed day is day ten, and its task is swimming a distance. Give the distance a measure: six kicks, one push, and your fingertips touch the wall. Counting movements beats writing that you reached the other side. End with one honest feeling from that day; skip the big lesson about perseverance.

What about the other seven days? Add one or two short bridges, such as swallowing water again on day three or floating alone with the board on day seven. Merge the rest into one line: the middle days were all breathing practice, slow progress but no retreat.

One last trick: open each entry with the weather or water temperature, such as a blazing sun and water that felt warm. These small observations turn a stack of diary pages into a real observation record.

One more point: the three detailed days must keep their order. Some writers want to put exciting day ten first, then look back at day one. An observation diary follows dates. The fear of day one exists precisely to contrast with day ten; keep the order and readers will truly cheer for you on day ten, while still worrying about the you of day one.

十天观察日记范文：从不敢下水到碰到池壁，附逐则点评

下面节选一篇四年级观察日记的三则，每则后面跟一段点评，看看好日记好在哪，自己写的时候照着改。

第一则：十月一日，晴。今天第一次下水。水刚漫到肩膀，我的心就跳得很快，像有人从里面敲门。我双手扣着浮板，指节都白了，教练让我把脸埋进水里，我摇头，水花溅到鼻子上，呛得咳了半天。点评：这一则没有写一个怕字，但敲门的心跳、发白的指节、溅上鼻子的水花，全是怕的证据。写情绪不用点名情绪，把身体反应摆出来就够了。

第二则：十月五日，多云。今天练漂浮。教练托着我的背，让我全身放松。我一开始绷着，身子像一块木板压在水上；后来一松，肚子反而浮起来了，耳朵在水里嗡嗡响，像隔着一层墙听人说话。手一抬，脚就往下掉，原来人是靠后背躺在水上的。点评：绷着沉、松着浮，这个反常识的发现就是观察日记最值钱的部分。嗡嗡的耳朵是把听觉写进了日记，很多孩子只写眼睛看到的，忘了耳朵和皮肤。

第三则：十月十日，晴。今天不扶板了。我蹬壁出发，数着自己的动作：划手、蹬腿、划手、蹬腿，数到十二下，指尖碰到了池壁。我扒着池边喘气，水从下巴往下滴。十天，我从不敢把脸进水里，到游完了一整条泳道。点评：数到十二下是全文最亮的一笔，距离被数出来了，进步就有了刻度。结尾只写喘气和水滴，没有喊口号，反而让人信服。

三则连起来看，会发现详写的只有三天，中间的日子全部跳过。这正是观察日记的写法：不求天天有，但求写下的每一天都有画面、有证据。

自己改的时候，可以照着三步做：第一步，给每则日记补上日期和天气，让它先像观察记录；第二步，删掉重复的感叹，把同一句高兴只留一次；第三步，挑出画面最多的三则详写，其余合并成过渡句。改完把三则连着读一遍，如果读的时候脑子里能出现池边的画面，这组日记就算成了。

A Sample Ten-Day Observation Diary: From Fear to Touching the Wall, With Notes on Each Entry

Below are three entries from a fourth grader's observation diary, each followed by a short note showing what makes it work, so children can compare and revise their own pages.

Entry one: October 1, sunny. First time in the water. When it reached my shoulder, my heart pounded like someone knocking from the inside. I gripped the kick board until my knuckles went white. The coach asked me to put my face in; I shook my head, water splashed onto my nose, and I coughed for ages. Note: the entry never uses the word fear, yet the knocking heartbeat, white knuckles, and splashed nose are all evidence of it. Show the body, not the label.

Entry two: October 5, cloudy. Practicing floating. The coach supported my back and told me to relax. At first I stayed stiff, a board pressing on the water; then I let go, and my belly rose instead. My ears hummed under the surface, like hearing people through a wall. Lift a hand and the feet sink, so the body really lies on the water by its back. Note: stiff sinks, relaxed floats is a counterintuitive discovery, and discoveries are the most valuable part of an observation diary. The humming ears bring hearing into the page; many children only write what eyes see.

Entry three: October 10, sunny. No board today. I pushed off the wall and counted my moves: pull, kick, pull, kick, up to twelve, and my fingertips touched the wall. I hung on the edge gasping, water dripping from my chin. Ten days ago I could not put my face in water; today I finished a whole lane. Note: counting to twelve is the brightest stroke in the piece, because distance gains a scale and progress becomes measurable. The ending shows only gasping and dripping water, no slogan, and that is what convinces.

Read together, only three days are written in full; the middle days are skipped entirely. That is exactly how an observation diary works: not one entry per day, but every written day carrying a picture and evidence.

When revising your own set, follow three steps. First, add a date and the weather to each entry so it reads like an observation record. Second, delete repeated exclamations and keep each happy sentence only once. Third, pick the three entries with the most pictures to write in full and merge the rest into bridges. Then read the three entries straight through: if the pool edge appears in your mind while reading, the set has succeeded.
