【正文】 news that Dolly had been born was announced in 1997. However, Dolly‘s death raised many opinions about cloning. Personally, I would like to agree that cloning may do no good to our human beings. Firstly, seeing Dolly, we may think that cloning animals can easily develop a disease. They can‘t live long. Secondly, we can‘t clone animals that have been extinct longer than 10000 years, even if the DNA of dinosaurs could survive this long. Thirdly, based on what we know now, human cloning is just a matter of time but the assumption that human clones have already been born hasn‘t been proved yet. In one word, personally, the chances of cloning animals and cloning human beings living on the earth naturally are merely a dream. Assignment 1. Try to correct the position . 2.
