Animal experience 800 words universal

When we have new experiences in life, we can record our thoughts anytime and anywhere. Experience helps us sum up the experience of things. What do you usually write about your experience? I specially collected and sorted out the animal experience, so I might as well refer to it. I hope you like it!

Animal Experience 1 Our experiments are all done with nude mice. In the previous experiment, I had a needle, 4-5 needles, but I didn't get a needle. Later, a nurse from our department came to stick it, but it couldn't get in! Moreover, it is stressful to compare the experimental group and the control group, so the amount of tumor cells that need to be scored should be the same! The little boss is very strict. If he can't play well, he will be criticized!

Naked mice are expensive, and the practice space is small! Later, other experimental groups in our animal room had to deal with the mice after the experiment, so I begged them to let the nude mice die somewhere else, and I helped him raise them, then I could practice. Later, after my own exploration and contact, the probability of successful injection of tail vein is above 80%. The experience is summarized as follows:

2. Put the mouse into the device just now. Before tail vein injection, soak in a water bubble at about 50℃ for 65438 0 minutes. Never use very hot water, it will burn your tail off and then get infected. After soaking, you will see that the tail vein is obviously filled (this step is very important).

3, and then it's time for an injection. At first, I was looking for a plane, that is, a plane that can make the tail vein parallel. I can stand up or pull the tail vein into a plane by hand! The general principle is to flatten and tighten the tail vein.

As long as you stick to your dream, even if people around you laugh at you, even if you will give your life, don't give up and don't be disappointed, because as long as you stick to it, it will definitely come true!

Zootopia has benefited me a lot. Persistence, cute and brave rabbit Judy, handsome and smart fox Nick are all examples I want to learn. Judy had a dream since she was a child, that is, to be a policeman. Through hard work, she succeeded in becoming a policeman and met Red Fox Nick. Although the intrigue of Vice Mayor Yang was difficult to deal with, and he almost paid his own life, they worked together for the ideal of Qi Xin and finally succeeded. Judy is really great. She became a friend of Mr. Da and beat Vice Mayor Yang with Nick. If I were you, I would do the same, but it might be slower. Of course, the most handsome, cool and talented person is Nick. He saved America again and again, but his childhood was so bad that he was laughed at and bullied by his friends. So he vowed not to let anyone see his weakness. Of course, what makes me laugh is lightning. Although he speaks slowly, driving is powerful, steady and fast, which makes me laugh.

I also have a dream, that is to be a star, a shining star. When I fail again and again, I fall. I stand up again and again, but when I encounter problems, I am a little nervous and worried. But I still stood up scarred and continued to climb, because there is only one road to success, and-work hard!

In today's modern life, human beings are the best in the world, and animals are just humble accessories for some people. They can hurt as much as they want, and abuse as much as they want. For example, 56 rare animals were killed a few days ago, and some were caught outside. It's because they won't cry out for pain or injustice. Although not everyone agrees with this idea now, cruelty to small animals happens from time to time. You know, human ancestors evolved from these small animals. Therefore, we and these small animals are originally a family, and the family should help each other happily and help those stray cats and dogs. In that case, why should we kill each other? Animals are good friends of human beings. Why should we hurt them? Take the following as an example! On a sunny afternoon, Yang Yang and some good friends and I went to explore the ancient forest. As soon as we got there, we found a doll-like thing wrapped in bedding in a cave and asked adults to come and have a look. Wow! It was an unrecognizable puppy, with several deep scars under its white fur, as if it had been beaten by someone, beaten with a whip, and a rib mark on its neck. The dog's hair is scattered on the lawn, which makes people feel particularly sad. After returning home, I thought a lot: some people will only be cold-blooded killers with the sign of protecting animals. They don't think from the standpoint of small animals, but only care about their own happiness and build their happiness on the suffering of others. In recent years, réndà has caught sharks for an expensive shark fin soup and a shark skin swimsuit. As long as you are happy, everything else seems to have nothing to do with yourself. Small animals are also alive. Don't look at those land and sea killers. They need to be taken care of like people. If there were no animals on the earth, it would be a lifeless world. Just like we can only see the endless blue sky, but we can't see the white clouds with different shapes in the sky. So let's all protect animals, so that our home will become better!

Animal experience 4 1, each animal has its own personality.

Ma-Bosek: I have a strong body and I have been working hard all my life. My dream is to build a windmill on the farm in my lifetime and live in that stable at retirement age. As a result, he couldn't get a pension when he reached retirement age, because the selfish pig, the ruler of the farm, was killed by Napoleon after he was injured in a work accident.

I've been with Bosek all my life. Because Bosek works too hard, she also works hard, and wants to help Bosek share some workload and make Bosek easier. Unfortunately, she saw Bosek being put on the bus at the slaughterhouse, and mobilized other animals to save Bosek, without success. Besides, she has another identity. When the seven commandments of the farm are broken, she will go to the commandments card to remind other animals, although her reminder has no effect.

Ma-Molly: Stupid and beautiful white mare who likes red ribbons and candy. After the animals occupied the farm, she had no more sugar to eat, and it was also stipulated that she could not wear ribbons. After seeing that one farm could not kill thousands of troops, she secretly ran to another farm, where she had her favorite red ribbon and favorite candy.

Pig Squealer: Napoleon's men are mainly responsible for brainwashing and reversing right and wrong. I don't know whether he is a successful brainwasher or other animals on the farm are brainwashed too easily. When the other animals saw the truth, Squealer persuaded them a little, and the other animals believed him.

Pig-Napoleon: Napoleon was an outstanding pig, good at planning, and finally drove Si Nuo Bauer out of the farm and realized dictatorship. Napoleon is a model of selfishness. He reminds me of King Shang Tang. He built his luxury on the hard work of other animals and tried to squeeze the proletarians.

There is another character who forgets who it is, has some wisdom, but is willing to be mediocre. Other animals, hey, don't talk about it, they get angry when they talk about it. What is worth pondering is, what role do you play in life?

Animals try their best to overthrow Jones's management. Napoleon is not the second Jones. Other animals have never left the farm and don't know the outside world. They were frightened when they heard Squealer lie that Jones was back. Napoleon's nine hounds barked fiercely and tore you to pieces after you confessed your unwarranted charges. Isn't Napoleon more terrible than Jones, but other animals don't know it.

This novel is relatively short. I finished my spare time at work in one day yesterday. Although it is short, there are many problems worth thinking about.

This afternoon, my parents and I went to the cinema to see a film called Zootopia. I will introduce this film to you.

This film mainly tells the story of a rabbit named Judy in Rabbit Nest Village. He really wants to be a policeman. It never gave up this dream, because no rabbit has ever been a policeman in Rabbit Nest Town. Although some people laughed at it, it didn't give up. Finally, through Judy's unremitting efforts, he became the best policeman.

Judy came to the animal city police station, and both the director and her classmates looked down upon her. Judy was assigned to the street to carry out traffic and post tickets. Very unhappy. Director Niu was criticizing Judy when someone came to report that 14 animals were missing. The angry director Niu saw Judy and asked Judy to solve the case within two days. If she can't finish it, she will go back to Rabbit Nest Village.

The clever Judy asked the fox swindler to help him finish the case by recording. The most interesting thing is that they checked the license plate. The sloth working in the DMV is really slow! Every movement seems to be in slow motion. Under normal circumstances, there will be a sudden mistake, and as a result, a license plate will be found from early to late.

They successfully solved the case after experiencing a difficult danger, but the case is not over yet. When Judy returned to Rabbit Nest Village, she found a flower called "Cow Night Howl". I heard that Uncle Judy ate this flower and bit Mother Rabbit. Judy suddenly found something else in the box and went to the fox to explain the misunderstanding. It turns out that the real behind-the-scenes person is Deputy Director Yang, and she planned everything.

After watching this movie, I feel that "whether you are big or small, as long as you are willing to work hard towards your dream, everything will come true."

I read a book these days, and its name is Animal Encyclopedia. This book is very thick, with more than 500 pages. It is divided into two parts. The first part is about the kinds of animals, including those in the sky, those in the water and those on the ground. The second part is about what you can't expect in the animal contest.

Let's introduce animals first. All the animals mentioned in the book are great. The law of nature is the law of the jungle. I will talk about the most powerful animals. Sharks have dagger-like teeth, a pair of clairvoyance, the most powerful nose in the world, thermal sensors, radar and streamlined body, which makes them the perfect underwater overlord. There are many kinds of it, such as lemon shark, great white shark, double halberd shark, whale shark and so on.

Let's introduce 009 in Skyhawk. It has a pair of keen eyes and flies freely in the sky. When flying in the air, it is actually looking for prey. Once it finds its prey, its eyes are fixed on it, and it can sneak past it with lightning speed and catch it at once. But this kind of animal is very rare, because humans use a lot of pesticides, which makes the eggshell under the eagle very thin and easy to break, which affects its reproduction.

Animals are wonderful, we humans are on the earth, but have you ever thought that humans are destroying the natural environment day by day, making it impossible for animals to survive? Scientists predict that if human beings continue to destroy the environment at this rate, coral will be the first extinct species on earth, this biological chain will be broken, other species will also perish, and human beings will disappear.

I have been in California for 1 month. I just got my school ID card yesterday, and finally I can formally receive animal experimental training. This morning, an Indian doctor was supposed to be in charge of training, but later she had to go to class and temporarily changed to a China doctor (he didn't speak Chinese, and I only heard him say "haircut"). This doctor Chen is very chivalrous, and he takes the initiative to help everything. He told me that he was at my disposal these days, which moved me very much. This article is also a summary of the experience of the United States in 1 month.

What I want to learn is how to make an animal model of brain injury after neurosurgery, that is, to cut off about 1/6 parts of the mouse brain. The most important thing in this experiment is to keep the consistency of the operation process. Because the operation is prone to cerebral hemorrhage, the operation should be as gentle as possible.

I came to the lab early before 9 o'clock this morning. 10, Dr. Chen came over and said, we can start now. I said it was a pity that 12 had to leave, because my daughter's physical examination was scheduled for 1, fearing that the first experiment would not be finished. The implication is that I will wait until tomorrow. He said it doesn't matter, you can leave at any time to any extent. I said to myself how embarrassing it was. If the experiment is halfway through, the teacher will be responsible for the follow-up arrangement. But I also wanted to start work early, so I accepted it. After all, it was a little sudden at first. I intend to finish all the work independently under his guidance. As a result, he helped me do most of the things, including taking animals from the animal room to the laboratory, preparing surgical instruments and preparing surgical microscopes. In the whole experiment, almost all the preparatory work was done by Dr. Chen, and I only did the core work. I remember that when I was studying for a doctorate in China, many technical jobs started with apprentices.

Because it was the first time to do this experiment, the movement was slow, and finally the brain was cut off at 12, so there was no time for later suture and animal care. These contents are left to Dr. Chen.

Before we started, Dr. Chen asked me why I used this model. Isn't this model used for cerebral hemorrhage? I say it mainly because I think this injury is a planned injury, which is more in line with clinical practice and very suitable for pretreatment research. In addition, I think it is rarely used in China at present, and I hope this model can be introduced into China. He was very happy after listening to it. He thought my opinion was good, and so did he.

Combined with the recent internship training, I think there are many places worth learning in animal experiments here. Here are only a few experiences for the time being.

First, the management of animals is very strict. The conditions in the animal room are very good, even better than the sanitary conditions in the laboratory. The living space is clearly divided, and there can only be two mice in a big cage. You must register to enter the animal room and take away a few animals. The serial number of the animal and the purpose of the experiment should be recorded in detail.

Second, the record of the experimental steps is very detailed. Detailed records can better reflect the specific experimental process. Each animal has a file, number, weight, anesthesia time and operation time, and each specific operation step is recorded in detail. After the animal model is made, it needs to be registered and returned to the animal house after it is properly restored. Before killing animals, everyone needs to record their behavior and observe and record the general situation of animals. Then the animal is killed, and euthanasia must be used to kill the animal. After the animal is killed, the brain should be taken out for photographic recording, and then the brain tissue should be processed according to the experimental purpose. In short, the whole process of animal experiments is recorded in great detail. If that animal is likely to have abnormal results, you can go back and find the reason. In the past, many teachers often suggested making original records when supervising graduate students' training, but they all emphasized how to standardize the record book and didn't care about the content and details. In fact, this method is not an ideal recording method. The original records don't have to be reflected in a book.

The third is the spirit of cooperation. I have been here for a month, and the most frequently asked question is, what research do you want to do? Can we talk? In fact, everyone is very concerned about other people's research content, and we can discuss it with each other at any time. You can also see what we ask each other at any time, and many people come out and ask how to explain it. My research involves several basic contents, one of which is animal model, because I have never done it before and need to learn it from scratch. In this way, at least half of the people in this group take the initiative to ask for guidance. Even those who don't take the initiative to watch their experiments will always stop to show me and patiently explain the details to me. The general feeling is that they all want to impart all their experiences and skills to you without reservation. Another research content is animal behavior test, which is a double-blind control because it needs the help of others. As a result, someone has made an appointment to help solve it. In a word, the spirit of mutual cooperation is very common here. You won't see anyone afraid that others will know your thoughts and master your unique skills.

Zootopia is a surprise, so I suggest you go to the cinema! I always thought that China's cartoons were for children and American cartoons were for adults! I watched Inside Out last year and benefited a lot. I want to say that this movie has given me more surprises!

Friends say this is America, and this is a question of racial integration.

I said, for people like me who don't like thinking and thinking when watching movies, and for beginners like me who learn to appreciate and appreciate movies, I'm not good at this grand analysis. What I want to talk about today is also my understanding of combining my life with movies in recent years!

Judy rabbit is the main character in the movie. From this, we can see the shadow of Qian Qian's real life. Maybe you, you, you! Now let me tell you what time it is!

1, Judy Rabbit's dream is to be a policeman and make everyone's life better! In the eyes of many people, this is simply a delusion, so it has been ridiculed and hit by many people, including their parents. In the secular view, rabbits can only grow carrots on farms, and the protection of world peace is left to those animals that are huge or fierce in nature. But Judy Rabbit is not bound by these secular eyes, but insists on her dream and must be a policeman. In our real life, how many people's dreams are stifled by others' eyes and parents' expectations. How many people can really stick to their dreams and not be influenced by others? But Judy Rabbit did it. She encountered many difficulties in customer service, graduated from the police academy with excellent results and became a real policeman. I think many people think this is an old-fashioned and tacky plot with some idealizations. Because of the gap between reality and dream, I think everyone knows that I failed to stick to my dream anyway and chose a road that others expected. I think only I can understand this pain and suffering. Sometimes, when we are faced with a choice, we have to ask ourselves whether we are willing to enjoy the praise of others or to obey and appease our hearts. Of course, I have experienced setbacks that are not setbacks in recent years. What I finally understand is that life is my own, and all roads must be chosen by myself, so that there is motivation. If you live according to others' wishes blindly, you will feel like a walking corpse and lifeless over time. In addition, your choice should be able to bear the consequences and be responsible for yourself. No matter which way we choose, we can live a good life, that is, try to get what we want and lose what we gave up, that's all!

2. Nick Fox, who appeared as a liar at first, finally found himself misunderstood when he was a child, thinking that the fox was cunning and untrustworthy, so he finally chose to be the bad guy in others' eyes to protect himself. This incident tells us that we must be kind to people and things around us. Sometimes, a small expression or a faint sentence of yours may have a great influence on others, even for life.

3. Judy Rabbit thought she had succeeded after catching the mayor of the lion, but found herself disrupting the life of carnivores and making them live badly. Very depressed and sad, I left my beloved police post voluntarily. When the reality and its dream hit again, it chose its own heart. Although its dream has always been to be a policeman, it found that the purpose of being a policeman was to make everyone live better, but found that it could not be done, so it chose to give up. In fact, sometimes it is more difficult to give up than to persist.

Courage is the most precious treasure in Judy Rabbit, and it is also what I lack. Judy rabbit bravely walked well on a road that no one else was optimistic about. It didn't give up after encountering difficulties, but faced difficulties and overcame them by giving full play to its own advantages; After hurting friends, it can bravely apologize and seek forgiveness from friends; When I found that I had done something wrong, I dared to take it and finally caught the real behind-the-scenes person.

Its courage is what I need to learn most.
