One possible version: Together with the modernest advances in science and technology, the news that Dolly had been born was announced in 1997. However, Dollys 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 cant live long. Secondly, we cant 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 hasnt 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. Assignment1. Try to correct the composition .2.
