小作文题目是：The graph below shows percentages of different types of household waste which were recycled in one city between 1992 and 2002.Summarize the information by selecting and reporting the main features，and make comparisons where relevant.
该柱状图难度中等，包含项目较多，既有动态趋势变化又有静态对比。不管题目多么复杂，先抓重点3W(when, where, what)。该图包含有三个过去的年份1992, 1997, 2002(when) 和4种家庭垃圾(what)的对比， 地点为某特定城市。时态为一般过去时或者过去完成时。考生可以以年份为主线分段也可以按照项目分段描述。
The bar chart compares 4 categories of domestic waste in terms of their recycling proportion in one specific city over a decade from1992 to 2002.
Generally, it can be seen that the household sectors had relatively low recycling rates in 1992 especially for plastic as merely 11% of it was collected. The remaining three kinds of trash including cans, paper and glass stood at an almost equal percentage 13%.
Five years later, the situation turned better off. There was a moderate increase in the amount of plastic and paper reused. While the rise was particularly noticeable in glass which nearly doubled in its recycling, a slight drop was actually found in cans.
The following half decade witnessed an overall upward trend except plastic which kept constant at about 12%. More cans and paper were recycled, with the proportion reaching more than 20% and almost 30% respectively. Also noteworthy is that glass remained the principal waste materials, approaching to as high as one half.
Overall, the gap between these waste recycling had enlarged in these years and while the vast quantities of glass and paper were recycled , plastic and cans remained unpopular.
