Question:  Person1:     What are you reading about in that science magazine ?  
 Person2:  There are several interesting articles on recent scientific breakthroughs . I just finished reading one about cloning .  
 Person1:      I ’ m not sure I like the idea of that . I don ’ t want people copying me or other people . It could be very confusing .  
 Person2:  According to the article , you have no real need to worry . Research nowadays is focussing on cloning parts of a human body to replace damaged or lost parts , not on recreating a whole human .  
 Person1:      In the future , that could be possible .  
 Person2:  In this article , scientists say that if you took the genes from someone and tried to create a copy of a person , there ’ s no guarantee that the copy would look or act like the original !  
 Person1:      Really ? What else have you discovered ?  
 Person2:  I read about how scientists are using material from plants and animals to create new medicines . For example , an animal be immune to disease that affects human . So , scientists find out why it ’ s immune  
 Person1:      That ’ s great , because it uses natural materials rather than ones that scientists make themselves . I prefer natural remedies to man-made ones .
