ladies and gentlemen,
i have had a lot of teachers in my school who have given me much help in my study. for their help i will never forget them. but today i am going to talk about a special teacher of mine. this teacher is not a human being and its name is“computer”. it has been teaching me a lot of knowledge and i appreciate it very much.
with the development of modern science and technology, computers are widely used in every teritories (1) including education. how can a computer be my teacher? how does a computer teach me? multimedia(多媒體)helps a lot in this aspect in recent years, and computer-based training (cbt) has become a popular educational medium (手段). even before the multimedia come (2) up, many different learning systems appeared, using the components and techniques we now associate with the term “multimedia”. multimedia components, such as graphics (動畫) , animations , sound and video, make the learning process easier through visualization. animations can present many complex subjects dynamically, but human teachers can not do this on blackboards.
multimedia makes our study more lively and interesting. for example, a cd-rom disk named “encarta encyclopedia” contains 650 mb
information including images, graphics, music clips, video clips, animations , texts, hotwords, and database search functions. fields involved includes physical sciences, performance arts, social
sciences, politics, military, education and so on. when pressing a button, i can hear american president clinton's speech clip. i may enjoy playing all kinds of musical instruments in the world. i can also see the animation of many physical phenomena. this makes
physical concept to be understood deeply (3). the audio features of
multimedia can greatly help me learning (4) foreign languages. with its speech output capabilities, i'm no longer dependent on an instructor for proper pronunciation.
how can i interact with a computer? there are many ways,
including keyboard, mouse pointer, and touch screen. i often use a
keyboard. when i press right keys, i can see and hear whatever i want. information world is at my fingertip. i wish that true speech input-output system would be invented one day.
as teachers, computers have a lot of virtues： they are positive, they have good memories and never lose any information stored in them. they have much knowledge in every field. they can let out all kinds of sounds, and can also improve the efficiency of our study. for example, if i want to, i can skip some chapters so that i can study at my own pace.
although computers will never take the place of human teachers, they are welcomed by more and more learners. computers will continue to evolve(發展)with the aid of modern technologies. computers are so powerful, helpful and important that everybody needs it, especially in the future! i love my computer teacher!
thank you.

Students, guests , teachers and Honorable Judges
Good morning !
My great pleasure to share my dream with you today. my dream is to become a teacher....
As the whole world has its boundaries, limits and freedom coexist in our life. I don’t expect complete freedom, which is impossible. I simply have a dream that supports my life.
I dream that one day, I could escape from the deep sea of thick schoolbooks and lead my own life. With my favorite fictions, I lie freely on the green grass, smelling the spring, listening to the wind singing, breathing the fresh and cool air and dissolve my soul in nature at last. Simple and short enjoyment can bring me great satisfaction.
I dream that one day the adults could throw their prejudice of comic and cartoon away. They could keep a lovely heart that can share sorrow and happiness with us while watching cartoon or doing personal things. That’s the real communication of heart to heart.
I have the belief that my dreams should come true. I am looking forward to some day coming when I am like a proud eagle, which flies to the blue and vast sky.
