One Possible Version：
Recently in my class there is a heated debate about“To clone or not to clone”．The students for cloning say that cloning can help the wildlife in danger，and we can have more and more wildlife in the world，and it can help the old and the sick，for example，some cloned organs can be tranplanted in their bodies．
However，the students against it say that cloning can speed up the rate of growing old and death．What’s worse，cloning Can make our society confused．There would be two or more of you，two and more of your parents and SO on．
In my opinion，cloning is new technology，SO socientists should do their best to make full use of it to help human beings．
Step 4．Homework
1．Finish the writing task．
2．Finish the rest of the exercises in the Workbook．。
