逸闻趣事以日常生活中的事情入手，描述一些鲜为人知的事。幽默故事是其主要内容。选材多来源于日常生活，给人似曾相识之感，但随着故事的发展、展开、结束，给人以意外的感觉。逸闻趣事类文章有以下趋势： 1．特点：文章简短，描述一个片断。 2．命题：多考查对事件的发生、发展和结局进行合理的推断。 3．选材：描述“另类”，标新立异。 In 2001，scientists at Texas AM University successfully cloned a cat for the first time，but this copy cat is no mirror image of the original.Copy Cat (CC) was the first cat ever cloned.In 2001，researchers at Texas AM University created the clone from the DNA of a calico cat (三色猫)named Rainbow after a failed attempt at cloning a dog. Interestingly，Rainbow and Copy Cat are different in many ways.Rainbows coat is brown，and white，while CCs is gray and white; Rainbow is shy，but CC is outgoing and curious. The differences in the two cats indicate that identical DNA wont necessarily create similar appearances or personalities because there are many other factors that contribute to both surface characteristics and temperament(性情)． CC has since gone on to have three healthy kittens(小猫) via the natural method，and the research that led to her creation became the foundation for a California—based pet cloning company called Genetic Savings Clone，Inc. However，the cat cloning project caused criticism from animal welfare groups，which pointed out that millions of cats are killed in shelters each year due to pet overpopulation.They argued that the large sums of money spent on creating more cats could be put to better use providing homes for strays. There are also objections to the cloning process itself.Many people consider cloning cruel，as it is a process that can lead to deformities and other problems，which is evident in the fact that many clones die within months or even days of creation. Much to the delight of animal welfare advocates(提倡者)，after cloning five cats in total，Genetic Savings Clone shut down in 2006.The reason for the companys close was its inability to make its cloning technology affordable and thus accessible to mainstream consumers. 1．What is the best title of the passage?
