There are many toys in my family, but my favorite toy is the high-tech gift "Remote Control Racing" which won the first prize in the popular science contest.

This car is 20 cm long, 9 cm high and 8 cm wide. The hood is gold, and the body is black and purple, which is very eye-catching, just like a wild cat. The four wheels are made of tank tracks. Although they are heavy, they can actually fly quickly on very smooth glass. Whenever I am free, I always like racing with my friends. Every time, my car is the fastest and smartest turning and climbing. Friends are envious.

My racing car also has a special function. The antenna on the roof can not only receive the instructions from the remote controller, but also predict whether there are sharp and dangerous obstacles ahead. If there is, it will send a signal to the remote control, and it will also send out an alarm sound of "beep, beep, beep". I will immediately reverse the car until it is safe. This antenna can be used in jewelry stores, museums and other places where valuables and documents are stored.

Once in the cold winter, we ran a race on the icy ground. When other cars meet a flat road, they spin around. The remote control doesn't work, but my car still runs very fast. Another time after the rain, my friends and I were going to a wetland competition. With the start, my racing car rushed forward at a high speed like a runaway wild horse. Unexpectedly, it rushed into the puddle. My friends and I are very worried. Everyone stopped and ran to check it out, but my car was safely out of the puddle. I lovingly and carefully wiped off the muddy water on it to prevent it from getting a little dirty.

I love this car! At this time, an idea came to my mind: I want to be a racing designer in the future and design a unique racing car, which can race on land, sail in water and fly at low altitude. It is a multifunctional high-tech racing car for sea, land and air, which will add more convenience and fun to people's lives.

There is a pomegranate tree in my yard. Before I was born, it had gone through eleven spring and autumn periods. Every day when I come back from school, it always looks at me, as if to say, "What's the matter? Are you still happy today? " Watching, every day's troubles seem to have disappeared. Our family took good care of him for a whole year.

In spring, pomegranate trees grow slender new branches and green leaves. I think it's time to take off his "cotton coat" for the pomegranate tree. On this day, it happened to be Sunday, and my cousin and I were fighting for the pomegranate tree to take off his cotton-padded clothes. Dad gave us a good idea. My cousin is young and starts at the bottom. I am tall, starting with the top rope. On the last lap, we both want to solve it. As a result, my cousin took an extra turn and was caught up again, which made us all laugh.

In summer, flaming pomegranate blooms, adding infinite charm to the lush pomegranate trees. From a distance, pomegranate flowers hang on trees like lovely little red corners, which makes people fondle. I can't help touching the lovely pomegranate petals, which are soft. I went up and smelled it, and a smell came to my nose, which made people crazy.

In autumn, naughty pomegranate babies cracked their mouths and the branches were bent. It's time to collect the bill. We have a division of labor, my father is responsible for picking pomegranates, I am responsible for collecting them on the left, and my mother is responsible for collecting them on the right. In less than 30 minutes, the bag was full of pomegranates. When I got home, I picked a pomegranate with a split mouth and broke it in half. I saw the dense pomegranate grains crowded but arranged orderly. I put a few in my mouth, a cool feeling, a gentle bite, and the sweet and sour juice splashed. When I taste pomegranate, I intend to give it to my relatives and friends, so that everyone can taste the fruits of my family's labor together.

In winter, the cold wind is howling, and we are going to put on cotton-padded clothes for pomegranate trees. Although the weather is very cold, we are still holding hemp rope with great interest. My father and I dressed pomegranate in cotton-padded clothes round and round, and my mother sent me and my father hot tea to supplement the heat. The pomegranate tree has been covered with cotton-padded clothes. I hope it will bear more fruits next year.

I love my pomegranate tree!

Lingfeng, plum blossoms are in bloom.

Walking into Lingfeng, I saw plum trees standing on the edge of the grass from a distance. Hongmei seems to have been dyed with pigment, and it is bright and dazzling. A piece of red plum looks like a bunch of jumping flames. As I approached, I found that there were still a few red berries in bud, and there was a small hole in the bud, like a bottle mouth, like a shy little girl blushing; A few flowers still show their faces; There are also some blooming flowers.

I was intoxicated with the beautiful scenery of red plums when suddenly there was a faint fragrance behind me. There is a plum tree behind me. In the distance, I saw a lot of Bai Mei blooming on that plum tree, as white as snow on the tree, and white butterflies playing in the branches. Nearby, the flower is like a golden bowl on a silver plate, with white petals and golden stamens, which are even more beautiful than the red plum.

A burst of laughter broke out at the edge of the plum tree. I saw an elderly man, leaning on crutches, slowly looking at the tree, seeing that this tree is beautiful and that tree is beautiful; An uncle stood by the Bai Mei tree, admiring the delicate plum blossoms carefully, and occasionally making some exclamation sounds; The children ran around the plum tree and played hide-and-seek games. I picked up a fallen plum blossom and stuffed it into my pocket.

Standing in the plum garden, I feel like a plum blossom, dressed in snow-white clothes and bathed in sunshine. I am happy to say hello to other companions and play with birds in the sky ... It took me a long time to remember that I am not Mei, but Mei.

Plum blossoms bloom in the cold wind. Whenever everything dries up in winter, plum blossoms still bloom proudly. In spring, everything revives, but plum blossoms remain alone. Could it have opened the door to spring?
