然后你就转折,写 however,if in detail,citizens rarely know why is envirenment protection so important and how to protect environment.
于是你开始给环境分类:personally,environment could be grouped as x,x,and x.
然后你对每个环境分类进行展开,叙述 重要性,还有你认为可行的保护方法.
结尾就写 as the pollution getting severe,environmental protection could not only be written in govenment document but also be implemented and the subconciousness of which within citizens should be built up for possitive protection instead of passive.
