today the point of my speech is my dream.as we all know,the dream is indisponsable to life.but,what do you think of dream?i think dream is worth the effort to win things.everyone has their own dream.maybe someone want to be a doctor,someone want to be a teacher or a business.similarty,i also have a dream:to be a cartoonist.maybe you will ask me:why?what I want to say is there is a world in comic.every one will have their own small world.and I hope to share my passion and my world to others.drawing anime is a very happy thing for me.i don't want to be excited about dreams with you standing here.because I know the road of dream can't let us sing songs.on the country,there's no such thing as a free lunch.if you want to achieve the goal must be to learn to give.nothing can be done easily.so I am going to continue trying and I believe I can realize my dream.this is what I want I want to share with you.thank you for your listening.
