- The school has an important role in communicating knowledge to students. Students can acquire knowledge from a variety of sources, but knowledge at the school remains the most important because it is standardized, highly accurate and oriented.
The role of the education sector in general and the school is very important in training talents, creating the nation's natural resources.
- In the school who directly impart knowledge is the contingent of teachers. They are all trained in the Pedagogical schools. They are not only skilled but also conscientious and ethical. So they always have a sense of professional development, updating information to improve the quality of teaching hours to give students the standard understanding.
- His father from a long time has greatly appreciated the role of the school in spreading knowledge. Van Mieu Quoc Tu Giam has been built since the first centuries of the feudal nation of Dai Viet. The advanced countries in the world are developing fast and strongly because they attach importance to the role of education, in which schools occupy the leading position.
- In the current information age, there are many sources of knowledge supply, the role of spreading knowledge from the school becomes more important than ever.
- In the transmission of cultural knowledge, in addition to the important role of teachers, students also need to have a proactive attitude.

The enveronment is everything around us, both natural and made by man. A major problem in the world today is the destruction of the natural environment.
This is complecated problem. We burn fuel and throw away plastic bags these cause pollution . We have made thousands of new chemicals, factories that made or use chemicals always chemical wastes. These are often poesonous, and thay also stay in the environment.
What should we do at school or at home to minimize pollution ? for me, We could pick up garbage littered and put it into a gabage bin, we can reuse bottles and cans, use banana leaves or papers to wrap foot, not throw trash into the water or ground. That is how we can keep the school yard clean and protect the environement.
Moreover, using the public buses can reduce exhaust fume and threefore we can keep the air cleaner.
I think that it is not enough simply to talk about the problem . We must act now before it too late to do anything about it . Join us now to protect the environment. That is how we can save the Earth.
