To begin with, competition contributes to the progress in most societies; filled with competition everywhere, the societies develop faster and better.
Competition makes factories promote manufacturing efficiency; competition gives workers a higher spirit to work; competition accelerates the pace of everyday life. It is through competition that outstanding people come out of a campaign; it is through competition that higher efficiency substitutes the lower one. Competition is demanded and cannot be obviated. In light of this, competition exists and results in progress in almost every aspect and no one could deny the importance of competition, and neither could they afford the disappearance of competition in any aspect.

Contemporary life calls for a lot of different forms of documentation; providing vivid colorful pictures with original sound, the video camera has become increasingly popular in many aspects in our life. A journalist chooses to report most of the news through video camera; A student may use a video camera to record his/her school life and bring it home to his/her parents and friends; A professor may record his lectures with video camera and thus all the students could have the opportunity to "attend" it even if they were in fact absent from the lecture when the professor gave it. Video cameras can serve us wherever you are, whenever you are. No one could deny the increasingly popularity of video cameras in our society.

As for the basic freedom, everybody has the right to pursue it. You can choose your hairstyle, the color of your shirt; you can decide which restaurant to have lunch and what kind of laptop you will buy. And women should have their right to care about dress and to go to work, as well as children should have their right to play together and to go to the same school. For all black people, as Martin Luther King, the great black civil rights leader said, the basic freedom to choose to stop all discrimination should not be deprived. History is always replete with such examples. Actually, in a democratic society, no one could deny your pursuit of your basic freedom of choice in your life.

It's true that the speaker's assertion that education catering to individual needs and interests has many merits. Needs and interests are part-and-parcel of the studying progress. They two are always referred to as the best teachers. The more useful and interesting a student finds a course, the more time and efforts he/she is willing to devote; the more time and efforts he/she devotes, the more progress he/she is likely to make in the course; the more progress he/she make in a course, the more interested he/she is in the course. Therefore, needs and interests serve a vital part, as expected in the studying progress, as ink is to a pen or wheels are to a car(类比/比喻).
Were it removed from our educational system, how can you imagine that our students would learn by heart a number of disciplines every day which they cannot find any interest in; how can you imagine that test-takers would remember everything they have recited after the examination is over; and how can you imagine that our teachers' feelings would not be hurt when they see their pupils just doodle the class away?

The root cause behind this social phenomenon can be traced back to the long-held belief that “Seeing is believing”; Featured by the fast pace of our contemporary society, there is literally no chance for people to get to know other people or things over the long term. Employers have to decide who to recruit after ten minutes’ interview; voters have to decide who to vote (to vote whom) after each candidate’s ten-minute speech; consumers have to decide which product to buy via comparing the colorful packages.
Quick decisions are demanded. No wonder that appealing first impression plays a crucial role in this process. In light of this, no one could deny the importance of good images, and neither could they afford the damage of public images. (from the Internet)
