主題：Shortage of natural resources(自然資源短缺)

　　The prolonged development of human society proves that population and economic and social progress eventually cannot be achieved without natural resources.To save the limited resources, we must take some measures to handle appropriately the relationship between the population and resources.

　　該段首先進行總結：人類社會持續的發展證明，如果沒有自然資源，人口的繁衍、經濟和社會的發展最終都是不可能的。作者接著建議，為了節約有限的資源，我們必須采取一些措施，正確處理人口與資源的關系。

　�、芴嵝炎x者事物的兩面性

　　文章的結尾還可以以轉折的形式，提醒讀者任何事物都有兩面性，從而認識到其不足或負面的影響。例如：

　　主題：Solar Energy(太陽能)

　　However, solar energy has its disadvantages.One is that it is still very expensive for widespread practical use.Besides, solar systems would not work in cloudy or rainy days as well as at night.But in sunny areas, solar energy could help solve the energy crisis.

　　該段指出了太陽能的兩個缺點：一、太貴;二、太陽能系統在陰雨天和晚上無法工作，從而讓人們更全面地了解太陽能。值得注意的是，在指出某一事物的另一面時，不能用太多筆墨，否則會喧賓奪主，淡化主題思想。

　　(4)巧妙運用名言警句

　　名言警句的巧妙運用不僅會使文章有一定的文采，論證更加有說服力，更能顯示考生的英語功底。另外能夠適時引經據典，必定會讓閱卷人眼前一亮。

　　1)開頭段：名言警句或俗語諺語等作為文章的開頭，既文采斐然，又能突出中心。例如：

　　Just as the saying goes, “ so many people, so many minds”, it is quite understandable that views on this issue vary from person to person.To this issue, different people come up with various attitudes.

　　2)中間段：中間段主題句之后引用名言警句，有力證明論點，起到錦上添花的效果。例如：

　　As a classic proverb goes that no garden has no weeds.Computers do play a positive role in the development of people’ lives, despite a slice of unfavorable impacts.We should ,therefore, take advantage of the fruits and avoid the opposite facet.

　　3)結尾段：用名言警句收尾，意在引申文章內涵，充分表明考生自己的觀點，極具說服力，收到“言有盡而意無窮”的效果，起到了畫龍點睛的作用。例如：

　　Therefore, we should never underestimate our own ability but should believe in the proverb: “Where there is a will, there is a way.” Confidence is a must for success.
