In this information age, computer is becoming more and more vital in many areas, and education field is no exception. As a result, a new question has been asked: whether the computer will replace teachers. Some people approve of it while others argue against them.

As far as I'm concerned, although the computer can get involved in the classroom and teaching procedure, teachers still can't be replaced by the computer. It has been universally acknowledged that teachers need the qualification, not all the people who acquire knowledge can teach students.Different age groups need different ways of teaching, which varies from infant to senior. If a student is confused about not only the result and calculation process, but also how to express their confusion appropriately, the significance of human teacher is conspicuous. They can illustrate the abstract question, point out students' s errors and remind to avoid similar eoorrs next time.

On the contrary, computer can just offer students a final result and calculation process.However, it can't contact students emotionally and help them handle some physical and mental problems.

Moreover, teaching students in accordance with their aptitude is important to students, but computer can hardly achieve it.

In a word, human teachers can't be replaced of computers simply because they have great and unique responsibilities, and computer can't assume them successfully.
