　　③反面論證：使用in addition to引出“綠色校園”的第二層含義，即create a civilized atmosphere for the sake of students’ mental health.然后舉例進一步解釋此含義。如：For example, students will be severely punished in case of cheating in exams and plagiarizing in academic papers.

　　常見問題：用語過于直白或極端。如：We must…/ We should…等。

　　使用對策：要站在中庸的立場上，客觀地提出建議，可使用一些表示客觀立場的詞語，如：It is essential that …; Only by the co�瞖fforts of the whole society could “green campus” work smoothly.這樣使自己的觀點表達得既委婉又客觀。

　　Creating A Green Campus

　　Nowadays the topic of a green campus has been widely debated which has aroused public attention.Undoubtedly, a green campus, the indispensable part for the development of college students, has a profound impact on both individuals and society, for its significance cannot be denied.

　　The idea of “a green campus” is beyond a green environment.To begin with, campus construction refers to green environment preservation and protection, such as planting more trees and flowers, which makes campus an ecological and natural resort, and advocating green products.For example, students are encouraged to avoid using disposable plastic containers in campus dining hall and recycle wasted batteries and other electrical products properly.In addition to the environmentally friendly practice, we shall make every effort to improve the moral standard and ethical level of university students in order to create a civilized atmosphere for the sake of students’ mental health.For example, students will be severely punished in case of cheating in exams and plagiarizing in academic papers.

　　To bring “green campus” to its full play, effective measures should be taken.First, based on its education function, campus should bring the theory of “sustainable development” into classrooms, set environmental management rules and conduct environmental education activities.Second, it is essential that law and regulations be worked out and enforced by the government and school authorities.Only by the co-efforts of the whole society could “green campus” work smoothly and bring benefit to people’s well-beings.

　　(四)修改潤色

　　1.檢查

　　2.潤色

　　例如：Only by the co�瞖fforts of the whole society could “green campus” work smoothly and bring benefit to people’s well�瞓eings中使用倒裝句的結構，凸顯考生的語法功底。
