One of the most popular hobbies among people is reading books.More and more people spend their spare time in reading the books they are interested in.There are so many books in the world that it's impossible for anyone to read all of them,even if he spend his whole life on reading.Before we started reading,we should find out whether it is valuable for us to read it.Reading good books is one of the greastest pleasures in life.It can enrich our knowledge.It makes us learn lots of things we did not previously know,we can be aware of what had happened in the past as well as what is happening in the present time.The more books we read,the more knowledge we get.No matter how much education we recieve or how much money we have.We can't become a full man unless we keep reading.Reading bad books will lead you to a wrong way and prevents you from progressing.It's worse than reading nothing.

    Through reading a book,you can communicate with its author without others'transmission,you can understand the author's thoughts.In this way,you also learn a lot of things,we can absorb intelligence and wisdom,we can also be taught lessons.

    For me,my favourate kinds of books are detective novels.It's really stimulate when I am reading a detective story.It can easily attract me.I think that reading such books can improve our logical thingking and we can get happiness from thses books.

    So let me end up my speech with a famous sentence,books are instrumental in stepping up human civilization.
