4. The composition "Golden October" is in urgent need of help. You can also contribute.
Spring is a beautiful season, summer is a colorful palace and winter is a silver world. What is autumn? Autumn is a golden brush, painting a dazzling watercolor painting. Xiao He composition network
Quietly, in autumn, she came to us with a smile. Like a fairy in a golden robe. Her light sleeves brushed away the heat of the scorching sun, but sprinkled freshness on the earth. Xiao He composition network
Slowly, the leaves turn yellow and fly down. Falling in the air, dancing like an elegant butterfly. Swish swish ... Pave a golden road, and it will be as soft as a carpet. Grass babies also changed into yellow pajamas, got into the warm embrace of Mother Earth, and fell into a sweet dream. Xiaohe composition network can also contribute.
By the stream, fish are playing in the water and frogs are singing happily. A little reptile is lying on a leaf, covered with a leaf, and sleeping lazily. There are two small ants who push a big leaf into the water with great strength. They sat on it and started their journey in the water. Chrysanthemum girl How brilliant it is to have a smiling face. There are red ones, pink ones and white ones, but Jin Ju is even more dazzling. Hard-working little bees carry small honey buckets and exchange beautiful songs for nectar from Chrysanthemum Girl.
On the Yuan Ye, there is a golden ocean. Look, in the orchard, big red apples are smiling at us, and fresh yellow pears are waving to us. The field is full of harvest. Wheat with big ears swayed from side to side with the breeze, singing cheerful songs. The farmer's uncle couldn't rest for half an hour, harvesting the hard fruit of a year with a sharp sickle. Jewel-like sweat trickled down their cheeks and backs and penetrated into their clothes, but it increased their joy of harvesting and their happy mood of returning home with a full load.
The sky is blue in autumn, and the sun is not as hot as before. Baiyun, like a little sheep, drifts around naughtily, enjoying the warmth brought by Grandfather Sun. Grandma Qiu Feng came, and those "little sheep" seemed to have taken "stimulants" and became lively. At the same time, it also sent a little coolness to the farmer's uncle.
Look, goose. They are arranged in the shape of "I" for a while, and in the shape of "people" for a while, flying to the south in an orderly way, bringing vitality to the blue sky. They will use this golden autumn to fly to the south for the winter. In the near spring, I think they will fly back with their babies.
Each season has different characteristics, such as plants sprouting in spring, Bai Niao competing for beauty in summer and heavy snow in winter. Autumn is a golden season and a beautiful season. I like autumn.
One day in October, I came to Lin Yuan Park in Liaoyuan City alone. First of all, Lin Yuan Park has four gold-plated characters hanging in the middle, and the trip begins.
First of all, I came to the Woods, which is the most beautiful at this time. These leaves swirl and fall like burning spirits, and rustle from time to time. If this is a painting depicting autumn, the artist's skill is too great.
Further down is the garden. At this time, it is the turn of chrysanthemums to compete for beauty. At this time, the fragrance of chrysanthemum is intoxicating. A bunch of red flowers also bloomed, and I looked at the place where a bunch of red flowers were planted. It was red. It feels no worse than a rose.
Walking into the field, the wheat in the field is golden and full, looking from a distance, like a golden ocean. At noon, the sun shines on the wheat, and some people go to harvest it and then carry it out, which naturally reminds people of the harvest season in the countryside.
Then there is the fitness center. I saw some grandfathers playing gateball, which was very good. I think this fitness center is specially designed for them.
Finally, I came to the fish pond. I see fish playing, goldfish and carp in the water. Look, look, there is a frog. This fish pond is really interesting!
I won't introduce some scenery one by one. I hope you can come and see it sometime.
639.8 billion writing analysis: This question can be written as a numerical sequence table. Write a few in the numerical list, and write 0 without looking; Omitting the mantissa after 1 100 million means rounding to 1 100 million digits. After rounding, omit the number after 1 100 million and write the unit "1 100 million".
... one billion, one hundred million, ten million, one million, one hundred thousand, ten thousand, one hundred, ten, one hundred.
3 2 8 0 0 0 0 0 6 0,
This number says: 3280000060,
328000060 ≈ 3.3 billion.
So, the answer is: 3280000060,33. Comments: Writing numbers with numerical tables can better avoid the situation of missing 0, especially reading a 0 in the middle of this problem. This is a common method, so you should master it skillfully. Pay attention to the difference between rewriting it into a number in billions and omitting the number after billions. The latter needs to be rounded to get a similar figure.
