life 和book有什么共同之处

1 before we start a life, wo don't know what will happen. and before we start to read a book,we also don't know what the book will tell us.
2 life is full of happiness and sadness, book comtains comedy and tragedy.
3 life has an end however. book has an end,too.

Ladies and gentlemen,
Thanks for your attending.Today I will make a speech which is about lives.
In my opinion,lives are just like books.In a good book it must
include people's happiness,sandness and a lot.When we read a book we have to turn over one page to the other,such aslives,
we must live day by day.What's more,every book has an ending
,every people will die.
Finally,thanks for your attending.
