What was the biggest mistake I made when I worked

When I just joined in my work,I didn’t know what I should care.Once after lunch I took the children to go for a walk.They lined up one after another and walked.Suddenly,I heard someone crying,so I looked for who was crying.Finally I found it was the last boy was crying.Then I asked him what was happened.He didn’t tell me and still cried.At that time,an older teacher came here and looked around the boy.Then she told me that he hit the door.She said :”Look!When he goes through the door,his head hit the door.There is a red bruises (不确定是不是能这样说)on his head.”At that moment ,I didn’t know what I should do.I was very nervous.That teacher gave me a towel with water and let me put it on his bruises.After while,the bruises on his head was not very red.
After class,When the boy’s mother took him away,I said sorry to her.That was my mistake.I didn’t take good care of her son.She was very nice.She said it doesn’t matter and didn’t care it. 
Through the accident,I know that I must look after every children.No matter where are they,I should look at them all the time.Don’t let them hurt and make them happy in the kindergarten.I won’t make these mistakes.This is my duty and work experience.

小细节稍加注意就是一篇还不错的小文了，继续加油~

How Internet Changes My Life

I had my first computer when I was(活学活用) ten years old.I was very happy that my parents bought it to me.Then I surfed on the internet.I searched for (单独的search sb为搜身)something about study and something interesting on it.
There isn't a computer in every family before 1990s.When my parents were children,they didn't know computer.If there were something important happened,they had to write a letter to tell distant relatives.It needed seven days or more days.That was too slow.
Now I have my second computer.I can listen to the music,watch the movies,study English,play the game,finish my work and talk to my friends on the internet.I can know everything in the world at home. My cousin is in another city.Sometimes we can see each other on the internet.It is very convenient and quick.
I am sure that internet changes everybody's life in the world.

Hola Hello, I am learning it one hour in the afternoon everyday!

The people who I hate

I hate the people who are hypocritical.Some people think they have a lot of money.They can buy big houses and expensive cars.In fact,a big house doesn't mean a happy family(这句超级赞~).If they think money is everything,they will be poorer and poorer.No matter where you live ,as long as you live with your love,you will be very happy.
I hate the people who are two-faced.Some people say something good to you  ,  (去掉逗号)when you are face to face.But behind you, they say something bad about you.I hate them.
I like the people who are easygoing.They are always happy and make me happier and happier.

The hardest problem I've met in my work

There is something difficult in my work.Because I'm a kindergarten teacher,there are many children in the kindergarten(maybe you can say "around me").They are very lovely,but sometimes they're troublesome.

When they came in the kindergarten in the beginning,they left their most dependable person.So they cried loudly.I had to coax them.To make matters worse,they cried more loudly and said "Where's my mother?I want my mother.Could you call my mother ,teacher?"I answered:"Your mother is going to work.She will take you away(pick you up) as soon as it is afternoon."At that moment,they stopped crying.(why don`t you describe how they change when they uesd to the life in the kindergarten?Because you use past tense in this paragraph. )

(you`d better start another paragraph.)On the other hand ,I‘m the closest person to them. Parents can't understand it is the hardest problem.Most of parents think their children are the best.In fact,children are overprotected at home.It makes their children are very naughty and selfish.They hit others for getting a toy and can't sit down in the class.I must criticize them.After all,I'm concerned about them.I hope they will become friendly and helpful.
To be frank,this job is very hard,we must help them to have dinner and put on their clothes.

After work,I feel so tired.Therefore,I need more understanding.

(Very good composition. It describes the true thoughts in your mind and is expressed correctly and clearly.✿✿✿✿✿)

BTW:Take a rest when you are exhausted~:)

Practice makes perfect

I think practice makes perfect.Whatever you do.（这第一句是啥意思？）（可以改成Whatever you do,I think practice makes perfect makes sense .（自己回去搜make sense））When I was a child,I learned to play the violin.I liked it very much.So I tried my best to learn and practice it every day.As a result,I could play the violin well.I was very happy.
When I had my first job,I could't doing anything(用know nothing about it比较好。你的本意是什么都不会做？).But I worked hard.I practiced drawing and playing the piano.If I had some questions ,I asked my colleagues for help.They were very helpful.
Now I learn English every day.I read English and recite words very hard.I often write some compositions.My English is better than before.After all ,I am trying my best.I do  believe that practice makes perfect.(do在这里是强调语气，我确实相信XXX。这里用believe in不太适合，不能做信仰的，还不如就用从句了。)
