Today I watched a movie named'The Butterfly Effect'.The movie told a very complex and special story.It told us something related to destiny,something related to our psychical world,something related to sacrifice...... 
    Evan,is a boy who lived in a single-parent family.His father was put into jail and was believed a mad man because he always saying that he could go back to the old days,he can make the present situation better. 

    Well,Evan,with his three friends,Tommy .Tommy~s sister Keathy and Nanly,did something extremly bad and horrible when they are yough Firstly,Keathy`s father was a (恋童癖患者），he foced Keathy act(儿童色情）with Evan when their only 7 as producing a (儿童色情片）。All the process was seen by Tommy who hide behind the curtain,and due to this reason he became a （虐待狂).
