参考答案和解析
正确答案：
My Opinion on Campus Disciplines In recent years, universities in China have tried to admit more students. While meeting public demand for higher education, these universities are usually troubled with various problematic behaviors on the students' part, such as skipping classes, eating breakfast in the classroom, and too intimate behaviors between student lovers. To deal with these problems, many universities carried out more strict disciplines. Though many students are against them, I believe that these disciplines are necessary and helpful.
First, these disciplines are necessary to establish a proper environment for teaching and learning. Teaching and learning are tough mental activities that require great concentration. If students eat breakfast in the classroom, they cannot pay attention to study at the same time. If students move in and out of classroom as they wish, the teacher and other students will definitely be interrupted. Besides, learning is also a long term process. If students skip classes frequently, they will not get a complete understanding of the knowledge system of the course, and thus be unable to learn the course well.
Second, these disciplines are necessary to prepare students for their future careers. Many students are not aware that there are very strict disciplines concerning one's behavior in the working place. If they do not cultivate proper mentality towards disciplines at university, they will not be used to disciplines in the future, and this will be a potential threat to their success. I learned from a friend that a graduate from a key university was fired because he had not followed the company's discipline of not coming to office late, and he admitted that he had been late for class frequently when he was at university. It can be seen from this example that if students do not cultivate a sense of discipline at school, they will have various failures in store for them.
Finally, strict campus disciplines are also necessary for the sound development of the society. Those who are against disciplines on the basis of personal freedom have a serious misconception about right and freedom. Being an adult does not mean you can do anything you like without caring about others' interests. If universities cannot dissolve this misconception before their graduation, these students may very possibly develop into people without due respect for law and regulations, and this may pose potential threat to the country's effort of building a law-abiding society.
From the above analysis, we can see that campus disciplines are indispensable. It can create environment to ensure educational quality, prepare students for future job market, and help cultivate a hw-abiding society. So we have every reason to call for more strict disciplines.
