Respect life

After people fully understand the mystery of life, it has become the dream of many people to assemble and modify life at will. This is neither Arabian Nights nor as simple as people think. However, this happened. That's cloning technology that ignores life. Its appearance has disturbed the world, and now a just voice is shouting: respect life and oppose cloning!

Life is the most respectable thing in the world. For thousands of years, people only know that it is unique. However, in June of 1986, 1 1, a unique boar was born in Baelz, USA. This pig is about the same size as an ordinary pig, but it has reddish-brown hair all over, a pair of squints squeezed into a wrinkled face, swollen legs and feet, and severe arthritis. It turned out that the researchers implanted a cow's growth hormone gene into the embryo cell of this boar, instructing the boar's cells to grow cow's growth hormone. The original intention of the researchers was to hope that boars would grow as big and strong as cows, but disappointingly, this did not happen. This kind of genetic pig has no significant attraction value to human beings. However, it has since announced to the world that the uniqueness of our lives is facing challenges.

10 years later,1August, 996, another shocking event happened in the field of biology: Dolly the cloned sheep was born at the Luslin Institute outside Edinburgh, Scotland. It was not until1Feb. 27th, 997 that scientists from Luslin Institute suddenly announced to the world that they had successfully cloned a sheep from somatic cells for the first time in the world. When the news came out, the world was in uproar. Some people hail this as an epoch-making breakthrough, while others exclaim that cloning will become a weapon to destroy mankind ... In short, Dolly, a little cloned sheep, has kept the relatively calm world of 1997 busy for quite a while. When Dolly officially began to face the world, seven months had passed. At this time, "Dolly" was snow-white, with slender and curved hair, a bulging nose and a Zhang Xiaohong card on her right ear, weighing 45 kilograms. Why did little Dolly cause such a big sensation? It is the first mammal cloned from somatic cells in the world. In the past, mammalian cloning technology only took the embryo out during the embryonic period and transplanted it into another egg, so that many twins could be produced, but "cloned sheep" was different. As long as the living cells of sheep are found, it is possible to replicate several sheep and dozens of sheep. ...

With "cloned pigs" and "cloned sheep", will "cloned people" be far behind? Although technically speaking, it is impossible to "clone" at present, who can guarantee that one day there will be such a frightening sound in a small corner of the earth: the clone "Dolly" was born and the world officially entered the cloning century! However, human beings are not fully prepared for psychological, physiological and ethical systems. Once the "clone" is born, human beings will be helpless. Imagine: thousands of Hitler and bin Laden appeared overnight, or "pirated". It goes without saying that life is no longer unique and precious, and the world will become chaotic.

Because of this, biotechnology is restricted by law. In the United States, human cloning experiments have been banned, and Japan, Britain, France and other countries have also introduced similar regulations. Some countries even ban research on cloned animals. Of course, scientists themselves don't want to be accused of being crazy. Dolly's father, Dr. Vermouth, repeatedly claimed: "We never thought about cloning human beings. Cloning human beings is meaningless for research. " ..... In short, it doesn't seem to be of much value to take pains to discuss the significance of the emergence of Dolly the cloned sheep, because its appearance is far from reaching a milestone height, and it is only a small prelude to biotechnology in the whole 2 1 century, although Dolly is so likable and world-famous. However, one fact that must be seen is that "Dolly" makes the only thing in life history.

People are seriously thinking about such a question: what will the world look like when biotechnology develops to omnipotence? When cloning appears, life becomes a replica, but cloning is a replica and can never replace life. Life should be unique in the world. Cloning is an invention that disturbs the world, a contempt for life and a weapon to destroy mankind. We should do our best to respect life and oppose cloning and reproduction of life! Let life always be the only and precious synonym.

Test analysis: The first material says that in order to make flowers bloom well, we must first raise the roots, stems and leaves of flowers. The second material said that running a new car, haste makes waste; Materials mean to cultivate talents, and it is harmful to pull out the seedlings and encourage them. Material 3 emphasizes that "it doesn't matter whether you are ahead at the start of long-distance running", and you may lose the race if you are eager for success; From the analysis of the materials, we can easily find their similarities: they all want quick success and instant benefit. From this, we can imagine that success can only be achieved by following objective laws or step by step. The best way of thinking: ① respect objective laws; Don't rush for success; (3) Laying a good foundation is very important for success; (4) Pay attention to accumulation, and accumulate over time; ⑤ We should have a long-term vision, not just look at the immediate interests.
