在以“我的老师”为主题的演讲会上，这篇演讲出人意料地将计算机称作自己的老师，以吸引听众的.注意。然后又用事实与推理证明计算机确实是一个“老师”，从而赢得了听众的共鸣。某些语言上的不足之处点评修改如下：
(1)在every后，territory用复数，显然是错误的。另外，表示“各个领域”，用field为好。
(2)原文时态用错了。
(3)concept是可数名词。make后的宾语补语如果是不定式的话，要省略to。另外，一般不用被动不定式，而只用过去分词。deeply也有中国式英语之嫌。
(4)help sb. (to)do，不用 doing。
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.
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(发展)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.
