Some scientists think that their preposterous① storylines are damaging the public understanding of science.Sidney Perkowitz, a professor of physics at Emory University in Atlanta, US, watched 123 sci fi films in 18 months while researching his book Hollywood Science. Speaking recently② at the American Association for the Advancement of Science, he said that many of the Hollywood's biggest scientific movies have begun seriously to affect the public's understanding of important issues. He named cloning as an example.“In a movie, if you clone a 30 year old, you immediately get another 30 year old, an identical③ twin with identical genetic make up.” he said.“In reality, you would have a new egg, which would turn into a new foetus④ and in 30 years' time you would have a 30 year old person. So there's a basic misunderstanding of how cloning works.” All around the world, teams of scientists are racing against time to collect DNA material from endangered animals before they disappear.They hope that if it is frozen and stored, it could help them to one day bring an extinct⑤ animal back to life with cloning technology.The program, called_Frozen_Ark⑥ ， was created by the Zoological Society of London ( 伦敦动物学会 ), the UK's Natural History Museum and the University of Nottingham. Scientists collect DNA material from animals in zoos and those in the wild and freeze and store them at the University of Nottingham.知识点击：①preposterous 荒谬的②speaking recently 为现在分词短语作状语，意为“当 / 在……时”。③identical 完全相同的④foetus 胎儿⑤extinct 灭绝的⑥called Frozen Ark 为过去分词短语作定语。
