雅思话题作文:电脑替代老师（2）

　　The computer is widely used in education，and some people think teachers do not play important roles in the classroom. To what extend do you agree or disagree?

　　In this period of communication,computer has been used in all kinds of fields widely, and plays a particular role in our lives. Especially computer has become more and more important in educational field, therefore dozens of people considered teachers could be replaced computers that will go with the current of the times. The above point is certainly wrong; this essay will outline three reasons.

　　The main reason is that peoples brain better than computer. Firstly, people design all kinds of computers programs. Secondly, computer doesnt have logistic ideation. Computer only can defend on that designer inputted computers programs to judge a questions right or wrong. In other words, computer cant defend on thinking that computer independently analyzes a questions right or wrong. In case, designer inputted programs that are wrong. Computer output the result that also will be wrong. If this kind of problem happened in classroom, students would be infused plenty of wrong information.

　　Another reason is that computers programs designed software of education that could be amended difficultly.If software of education of bugs were found, commonly these of problems couldnt be solved in the classroom. The software was amended that means total of program were corrected, not only parts of program were inserted or amended usually.

　　Last but not the least reason is computer is mechanical,it couldnt be suited all kinds of students and different demands. As students intellect is different, same of software couldnt base on every status of student to set a perfect project.

　　In conclusion, computers couldnt instead of the position of teachers in the classroom, however computer is an absolutely good helper for teacher.
