Every living thing has genes. Genes carry information. ¡¾1¡¿ They make sure that humans give birth to humans and cows give birth to cows. However, genetic engineers take genes from one species¡ªfor example, a snake, and transfer them to another¡ªfor example£¬corn£® ¡¾2¡¿ Such new life forms have been described as a real-life Frankenstein£®

Genetic engineers put duck genes into chicken to make the chickens bigger£®They put genes from flowers into beans and from fish into tomatoes£® ¡¾3¡¿ It just makes them easier and faster for the farmer to grow£®

The effects of genetic engineering on the natural world may be disastrous£®The engineers may create strange life beings£¬or monsters£®that we cannot contro1£® ¡¾4¡¿ They¡¯11have to find one£¬fight for one¡ªor kill for one£®It may be your land they fight for¡ªor you that they kill£®

We would all like a better£¬healthier and longer life£¬and genetic engineering might give us this£®On the other hand£¬it may be a dangerous experiment with nature£®In the story of Frankenstein£¬the doctor created such a terrible and dangerous monster that he had to destroy it£® ¡¾5¡¿

A£®In this way a new life form is created£®

B£®Then they feed the tomatoes to the fish£®

C£®This doesn¡¯t make them cheaper, tastier, or healthier£®

D£®The new life forms have no natural habitat or home£®

E£®They are passed on from generation to generation£®

F£®The information tells us what to do or what not to do£®

G£®We must make sure that this tale remains a story¡ªand no more than that£®
