My master is a naughty boy. He always forgets things at ordinary times and is looking for lost things in a hurry every day. Because of this bad habit, I was left on a chair in the park by him.

I sat in a chair for three whole days, which made my back ache and my legs cramp, and no one found me. On the third night, a strong wind suddenly blew, which made me dizzy and drifted into a small river unconsciously.

I drifted with the tide and didn't know where my destination was, so I floated on the water and fell asleep peacefully. When I opened my eyes in a daze, I couldn't help but be elated and drifted for a few days, and actually came to the blue sea.

Just as I was carefully observing the blue sky and sea, a huge net pulled me up with a large group of fat fish. It turned out to be a fisherman fishing! At this time, the fisherman found me and murmured, "Today is really lucky. I not only caught a group of fat fish, but also got five dollars."

After that, the fisherman went to the convenience store and bought a pack of cigarettes from me. The shopkeeper put me in a black wooden box.

I vaguely see many brothers and sisters locked up here, and an elderly grandfather (100 yuan notes have been crumpled). I twisted my injured little head hard and asked respectfully, "Old man, how long have you been here?" The old man screamed at the top of his voice and replied, "Cough … Cough … I have been here for so long that I don't remember.

Because my face value is too large, the shopkeeper has never found it out. Son, how did you get here? "Before I could answer, I was taken out by the shopkeeper and found a little boy.

On the way, the little boy playfully folded me into a paper plane and threw me out. I flew around in the air and landed on the roadside.

I can't help but say sadly, "Well, why don't people love me so much?" I'm going to wander again ... "Later, I was picked up by a little girl, then transferred to different hands, and went to different places, and I almost collapsed. Alas, I just wander around. I really hope people can treat me better! Otherwise, I will soon become as old as that grandfather.

3. How to write the composition of Band 4 on the back of one yuan scenic spot? The design on the back of the fifth set of RMB is very beautiful, with China's famous natural landscape, architecture and human history. What I like is the pattern on the back of one yuan.

On the back of one yuan RMB, the pattern is the famous three pools printing the moon, which is one of the ten scenic spots of West Lake in Hangzhou. Known as the first scene of the West Lake, it has beautiful scenery and quiet scenery, especially the three pools printing the moon. The pattern on the back of the dollar is really beautiful! The water in the West Lake is green, as if covered with a layer of turquoise gauze, and like intermittent threads, I seem to hear the gurgling sound of running water.

There are three stone towers in the water. These three stone pagodas defend the lake like three tall and straight soldiers. At the bottom of the stone tower is a circular base with an inverted semicircular bowl on it. Further up, there are five-hole round tiles. On the evening of August 15, the staff will put lighted candles inside. Each stone pagoda has five holes, one of which has fifteen holes, reflecting fifteen. It attracted countless tourists and sailed in the water on the night of 15 to celebrate this happy time with the moon. In the distance are rolling mountains, a stone arch bridge across the banks, next to lush forests.

One yuan is common, but there is such a wonderful scenery hidden behind it. I must go to Yin Yue Santan when I have the chance. :。

You come back from work at 7 o'clock every day to wash clothes, cook and check our homework. You raised me from a very young age to this age. Mom, I will help you with the housework in the future.

Mom, you have worked hard! You are too busy to eat well for our healthy growth. A few bites in a hurry will make you full, and you seldom eat it when it is delivered, resulting in a lot of nutrient loss. Mom, I have grown up. Mom, I love you!

How much my mother cares about me and loves me! Mom, my daughter will study hard and be a useful person.

7. Composition The second volume of the fourth grade buys about 900 words of stationery. On Sunday morning, when I was ready to do my homework, I found that I had run out of books and asked my mother to buy me stationery.

My mother looked at me gently and said, "You already know RMB, so practice it today. Go to the stationery store and buy it yourself!" " "Pass it directly to me 10 yuan. I thought: I will do my own thing, and I will finish the task.

So I took the money and set off happily. The sunshine in the morning is also radiant, and there are not many pedestrians along the way. Soon I came to the stationery store.

Ah! The stationery store has a dazzling array of goods, including neatly arranged notebooks, colored pencils and all kinds of rubber balls, which dazzles me. Just when I hesitated, my assistant aunt came up to me and said, "What do you want to buy, little friend?" I said, "Hello, Aunt, I want to buy some notebooks."

"Please come with me." Before coming to the counter selling books, my aunt made a detailed introduction. There are fruits, locks and cartoon characters, so I can choose according to my own needs.

I took a fancy to two beautiful sheep covers and took them to the cashier to pay the bill. One ***8 yuan brought back 2 yuan. I said to menstruation, "Thank you, menstruation. Goodbye. "

Aunt also waved goodbye to me. I skipped home, and my mother praised me for my skill.

8. The first time I went to the bank to withdraw money was in the composition "Extra 500 yuan" in the fourth grade of primary school. It was an unforgettable "first time".

That was in the fourth grade. In order to exercise my independence, my parents took me outside a savings office to explain the process and gave me a passbook for me to withdraw money myself. There aren't too many people in the bank, men and women, waiting in line in front of the window quietly.

Dad explained that finding a window with fewer people can reduce the waiting time. My parents and I have been to the bank several times, so I can't be regarded as a "rookie", so I quickly chose a row with fewer people to start waiting. After a while, I felt as if someone was waiting in line at the back.

I looked back and saw a middle-aged man with a beard. He was looking at me and smiling at me. I panicked. It's not a robber, is it I've seen a lot of gangster movies on TV. They all look like devils.

I quickly turned around and looked down. Those hostages squatted on the ground with their heads in their hands, and even the scene of being killed suddenly appeared in my mind. Won't be so unlucky? Suddenly I found my legs getting softer and softer, a little cold and a little calm! There are so many people in the bank that he won't rob them, will he? Usually robbers have accomplices. I began to look up and secretly looked around. Only seven or eight depositors. Which one will be his accomplice? "hello! Deposit or withdrawal? Huh? How is it a child? " A greeting interrupted my guess. The cashier should have just sent a customer away and was looking at me in surprise.

"What about you adults?" "I withdraw money, 500." I said in a voice that mosquitoes can't hear.

"Don't be afraid, son. What about you adults? " Aunt saver looked around with her eyes, but she was doomed to be disappointed. "I withdraw money, 500," I finally got up the courage to say loudly. "My father is waiting for me outside the savings office. I know the password! " "The password is ..." "Little girl, stop it. Enter it yourself later. Passwords should be kept secret. "

It's that scary uncle in the back! "Oh, thank you, uncle!" My uneasy heart finally let go, it seems that he is a good "egg"! "Don't be nervous, lose slowly and block with your left hand." Aunt saver smiled, too. "It's interesting that parents now come up with this way to exercise their children."

Don't be nervous, everything is going well! Holding 500 yuan's money tightly in my hand, I blushed and "escaped" from the savings office in the eyes of adults around me. It has been two years, but every time I pass by that bank, I have a wonderful feeling, because it is an unforgettable "first time" in my life.

If it helps you, please adopt it! ! Thank you ~ ~).
