【21年12月英语四级真题作文】In recent years, with the rapid development of society and the continuous improvement of people's living standards, the issue of environmental protection has become a topic of widespread concern. As an important part of the national education system, the College English Test (CET) often reflects social hotspots in its writing questions. The writing topic for the December 2021 CET-4 exam was "The Importance of Environmental Protection," which not only tests students' language skills but also encourages them to think about their role in building a sustainable future.

Environmental protection is no longer just a slogan; it has become a global responsibility. From the perspective of individuals, every small action can make a difference. For example, reducing the use of plastic bags, saving electricity, and recycling waste are all simple yet effective ways to contribute to environmental conservation. On a larger scale, governments and enterprises must take more active measures to promote green technologies and reduce pollution. Only through joint efforts can we achieve long-term ecological balance.

Moreover, the importance of environmental protection is closely related to human health and quality of life. Polluted air, water, and soil directly affect people’s well-being. By protecting the environment, we are actually protecting ourselves. Therefore, it is essential for everyone to raise awareness and take action from now on.

In conclusion, environmental protection is a critical issue that requires the participation of all members of society. As college students, we should not only master professional knowledge but also cultivate a sense of social responsibility. Through our actions, we can contribute to a cleaner and greener world.
