As we approach the 21st century，it is clearer than ever that science and technology are changging the way we live and work．The breakthroughs in bioengineering science are helping to reveal the mysteries of life，holding out new hope for lifesaving cures to some of our most dreaded diseases．

In 1997，the great news shocked the whole world that the British scientists created a lamb, named Dolly from a single cell．Miraculously，the cell had been taken from the under of an adult sheep，which marks the first time an adult animal had been successfully cloned．

But it soon caused worldwide concern over its ethical，social，and scientific implications．Cloning is especially controversial because it raises the prospect of“making”humans genetically idenfical to an existing man or woman．Some people claim attempting to use these cloning techniques to actually clone a human being is untested and unsafe and morally unacceptable．

How to look upon this new technique?When it comes to a discovery like cloning,we must move with caution，care and deep concern about the impact of our actions．First，cloning should be greatly esteemed and great thanks should be given to its inventors．Meanwhile，great efforts should be made to place this technique under strict control．Especially we should adopt a document against human cloning since past experience tells us a new invention may cause troubles if it is misused．
